-Perftools-Specific Install Notes
-================================
-
-*** Building from source repository
-
-As of 2.1 gperftools does not have configure and other autotools
-products checked into it's source repository. This is common practice
-for projects using autotools.
-
-NOTE: Source releases (.tar.gz that you download from
-code.google.com/p/gperftools) still have all required files just as
-before. Nothing has changed w.r.t. building from .tar.gz releases.
-
-But, in order to build gperftools checked out from subversion
-repository you need to have autoconf, automake and libtool
-installed. And before running ./configure you have to generate it (and
-a bunch of other files) by running ./autogen.sh script. That script
-will take care of calling correct autotools programs in correct order.
-
-If you're maintainer then it's business as usual too. Just run make
-dist (or, preferably, make distcheck) and it'll produce .tar.gz or
-.tar.bz2 with all autotools magic already included. So that users can
-build our software without having autotools.
-
-
-*** NOTE FOR 64-BIT LINUX SYSTEMS
-
-The glibc built-in stack-unwinder on 64-bit systems has some problems
-with the perftools libraries. (In particular, the cpu/heap profiler
-may be in the middle of malloc, holding some malloc-related locks when
-they invoke the stack unwinder. The built-in stack unwinder may call
-malloc recursively, which may require the thread to acquire a lock it
-already holds: deadlock.)
-
-For that reason, if you use a 64-bit system, we strongly recommend you
-install libunwind before trying to configure or install gperftools.
-libunwind can be found at
-
- http://download.savannah.gnu.org/releases/libunwind/libunwind-0.99-beta.tar.gz
-
-Even if you already have libunwind installed, you should check the
-version. Versions older than this will not work properly; too-new
-versions introduce new code that does not work well with perftools
-(because libunwind can call malloc, which will lead to deadlock).
-
-There have been reports of crashes with libunwind 0.99 (see
-http://code.google.com/p/gperftools/issues/detail?id=374).
-Alternately, you can use a more recent libunwind (e.g. 1.0.1) at the
-cost of adding a bit of boilerplate to your code. For details, see
-http://groups.google.com/group/google-perftools/msg/2686d9f24ac4365f
-
- CAUTION: if you install libunwind from the url above, be aware that
- you may have trouble if you try to statically link your binary with
- perftools: that is, if you link with 'gcc -static -lgcc_eh ...'.
- This is because both libunwind and libgcc implement the same C++
- exception handling APIs, but they implement them differently on
- some platforms. This is not likely to be a problem on ia64, but
- may be on x86-64.
-
- Also, if you link binaries statically, make sure that you add
- -Wl,--eh-frame-hdr to your linker options. This is required so that
- libunwind can find the information generated by the compiler
- required for stack unwinding.
-
- Using -static is rare, though, so unless you know this will affect
- you it probably won't.
-
-If you cannot or do not wish to install libunwind, you can still try
-to use the built-in stack unwinder. The built-in stack unwinder
-requires that your application, the tcmalloc library, and system
-libraries like libc, all be compiled with a frame pointer. This is
-*not* the default for x86-64.
-
-If you are on x86-64 system, know that you have a set of system
-libraries with frame-pointers enabled, and compile all your
-applications with -fno-omit-frame-pointer, then you can enable the
-built-in perftools stack unwinder by passing the
---enable-frame-pointers flag to configure.
-
-Even with the use of libunwind, there are still known problems with
-stack unwinding on 64-bit systems, particularly x86-64. See the
-"64-BIT ISSUES" section in README.
-
-If you encounter problems, try compiling perftools with './configure
---enable-frame-pointers'. Note you will need to compile your
-application with frame pointers (via 'gcc -fno-omit-frame-pointer
-...') in this case.
-
-
-*** TCMALLOC LARGE PAGES: TRADING TIME FOR SPACE
-
-You can set a compiler directive that makes tcmalloc faster, at the
-cost of using more space (due to internal fragmentation).
-
-Internally, tcmalloc divides its memory into "pages." The default
-page size is chosen to minimize memory use by reducing fragmentation.
-The cost is that keeping track of these pages can cost tcmalloc time.
-We've added a new flag to tcmalloc that enables a larger page size.
-In general, this will increase the memory needs of applications using
-tcmalloc. However, in many cases it will speed up the applications
-as well, particularly if they allocate and free a lot of memory. We've
-seen average speedups of 3-5% on Google applications.
-
-To build libtcmalloc with large pages you need to use the
---with-tcmalloc-pagesize=ARG configure flag, e.g.:
-
- ./configure <other flags> --with-tcmalloc-pagesize=32
-
-The ARG argument can be 8, 32 or 64 which sets the internal page size to
-8K, 32K and 64K repectively. The default is 8K.
-
-
-*** SMALL TCMALLOC CACHES: TRADING SPACE FOR TIME
-
-You can set a compiler directive that makes tcmalloc use less memory
-for overhead, at the cost of some time.
-
-Internally, tcmalloc keeps information about some of its internal data
-structures in a cache. This speeds memory operations that need to
-access this internal data. We've added a new, experimental flag to
-tcmalloc that reduces the size of this cache, decresaing the memory
-needs of applications using tcmalloc.
-
-This feature is still very experimental; it's not even a configure
-flag yet. To build libtcmalloc with smaller internal caches, run
-
- ./configure <normal flags> CXXFLAGS=-DTCMALLOC_SMALL_BUT_SLOW
-
-(or add -DTCMALLOC_SMALL_BUT_SLOW to your existing CXXFLAGS argument).
-
-
-*** NOTE FOR ___tls_get_addr ERROR
-
-When compiling perftools on some old systems, like RedHat 8, you may
-get an error like this:
- ___tls_get_addr: symbol not found
-
-This means that you have a system where some parts are updated enough
-to support Thread Local Storage, but others are not. The perftools
-configure script can't always detect this kind of case, leading to
-that error. To fix it, just comment out the line
- #define HAVE_TLS 1
-in your config.h file before building.
-
-
-*** TCMALLOC AND DLOPEN
-
-To improve performance, we use the "initial exec" model of Thread
-Local Storage in tcmalloc. The price for this is the library will not
-work correctly if it is loaded via dlopen(). This should not be a
-problem, since loading a malloc-replacement library via dlopen is
-asking for trouble in any case: some data will be allocated with one
-malloc, some with another. If, for some reason, you *do* need to use
-dlopen on tcmalloc, the easiest way is to use a version of tcmalloc
-with TLS turned off; see the ___tls_get_addr note above.
-
-
-*** COMPILING ON NON-LINUX SYSTEMS
-
-Perftools has been tested on the following systems:
- FreeBSD 6.0 (x86)
- FreeBSD 8.1 (x86_64)
- Linux CentOS 5.5 (x86_64)
- Linux Debian 4.0 (PPC)
- Linux Debian 5.0 (x86)
- Linux Fedora Core 3 (x86)
- Linux Fedora Core 4 (x86)
- Linux Fedora Core 5 (x86)
- Linux Fedora Core 6 (x86)
- Linux Fedora Core 13 (x86_64)
- Linux Fedora Core 14 (x86_64)
- Linux RedHat 9 (x86)
- Linux Slackware 13 (x86_64)
- Linux Ubuntu 6.06.1 (x86)
- Linux Ubuntu 6.06.1 (x86_64)
- Linux Ubuntu 10.04 (x86)
- Linux Ubuntu 10.10 (x86_64)
- Mac OS X 10.3.9 (Panther) (PowerPC)
- Mac OS X 10.4.8 (Tiger) (PowerPC)
- Mac OS X 10.4.8 (Tiger) (x86)
- Mac OS X 10.5 (Leopard) (x86)
- Mac OS X 10.6 (Snow Leopard) (x86)
- Solaris 10 (x86_64)
- Windows XP, Visual Studio 2003 (VC++ 7.1) (x86)
- Windows XP, Visual Studio 2005 (VC++ 8) (x86)
- Windows XP, Visual Studio 2005 (VC++ 9) (x86)
- Windows XP, Visual Studio 2005 (VC++ 10) (x86)
- Windows XP, MinGW 5.1.3 (x86)
- Windows XP, Cygwin 5.1 (x86)
-
-It works in its full generality on the Linux systems
-tested (though see 64-bit notes above). Portions of perftools work on
-the other systems. The basic memory-allocation library,
-tcmalloc_minimal, works on all systems. The cpu-profiler also works
-fairly widely. However, the heap-profiler and heap-checker are not
-yet as widely supported. In general, the 'configure' script will
-detect what OS you are building for, and only build the components
-that work on that OS.
-
-Note that tcmalloc_minimal is perfectly usable as a malloc/new
-replacement, so it is possible to use tcmalloc on all the systems
-above, by linking in libtcmalloc_minimal.
-
-** FreeBSD:
-
- The following binaries build and run successfully (creating
- libtcmalloc_minimal.so and libprofile.so in the process):
- % ./configure
- % make tcmalloc_minimal_unittest tcmalloc_minimal_large_unittest \
- addressmap_unittest atomicops_unittest frag_unittest \
- low_level_alloc_unittest markidle_unittest memalign_unittest \
- packed_cache_test stacktrace_unittest system_alloc_unittest \
- thread_dealloc_unittest profiler_unittest.sh
- % ./tcmalloc_minimal_unittest # to run this test
- % [etc] # to run other tests
-
- Three caveats: first, frag_unittest tries to allocate 400M of memory,
- and if you have less virtual memory on your system, the test may
- fail with a bad_alloc exception.
-
- Second, profiler_unittest.sh sometimes fails in the "fork" test.
- This is because stray SIGPROF signals from the parent process are
- making their way into the child process. (This may be a kernel
- bug that only exists in older kernels.) The profiling code itself
- is working fine. This only affects programs that call fork(); for
- most programs, the cpu profiler is entirely safe to use.
-
- Third, perftools depends on /proc to get shared library
- information. If you are running a FreeBSD system without proc,
- perftools will not be able to map addresses to functions. Some
- unittests will fail as a result.
-
- Finally, the new test introduced in perftools-1.2,
- profile_handler_unittest, fails on FreeBSD. It has something to do
- with how the itimer works. The cpu profiler test passes, so I
- believe the functionality is correct and the issue is with the test
- somehow. If anybody is an expert on itimers and SIGPROF in
- FreeBSD, and would like to debug this, I'd be glad to hear the
- results!
-
- libtcmalloc.so successfully builds, and the "advanced" tcmalloc
- functionality all works except for the leak-checker, which has
- Linux-specific code:
- % make heap-profiler_unittest.sh maybe_threads_unittest.sh \
- tcmalloc_unittest tcmalloc_both_unittest \
- tcmalloc_large_unittest # THESE WORK
- % make -k heap-checker_unittest.sh \
- heap-checker-death_unittest.sh # THESE DO NOT
-
- Note that unless you specify --enable-heap-checker explicitly,
- 'make' will not build the heap-checker unittests on a FreeBSD
- system.
-
- I have not tested other *BSD systems, but they are probably similar.
-
-** Mac OS X:
-
- I've tested OS X 10.5 [Leopard], OS X 10.4 [Tiger] and OS X 10.3
- [Panther] on both intel (x86) and PowerPC systems. For Panther
- systems, perftools does not work at all: it depends on a header
- file, OSAtomic.h, which is new in 10.4. (It's possible to get the
- code working for Panther/i386 without too much work; if you're
- interested in exploring this, drop an e-mail.)
-
- For the other seven systems, the binaries and libraries that
- successfully build are exactly the same as for FreeBSD. See that
- section for a list of binaries and instructions on building them.
-
- In addition, it appears OS X regularly fails profiler_unittest.sh
- in the "thread" test (in addition to occassionally failing in the
- "fork" test). It looks like OS X often delivers the profiling
- signal to the main thread, even when it's sleeping, rather than
- spawned threads that are doing actual work. If anyone knows
- details of how OS X handles SIGPROF (via setitimer()) events with
- threads, and has insight into this problem, please send mail to
- google-perftools@googlegroups.com.
-
-** Solaris 10 x86:
-
- I've only tested using the GNU C++ compiler, not the Sun C++
- compiler. Using g++ requires setting the PATH appropriately when
- configuring.
-
- % PATH=${PATH}:/usr/sfw/bin/:/usr/ccs/bin ./configure
- % PATH=${PATH}:/usr/sfw/bin/:/usr/ccs/bin make [...]
-
- Again, the binaries and libraries that successfully build are
- exactly the same as for FreeBSD. (However, while libprofiler.so can
- be used to generate profiles, pprof is not very successful at
- reading them -- necessary helper programs like nm don't seem
- to be installed by default on Solaris, or perhaps are only
- installed as part of the Sun C++ compiler package.) See that
- section for a list of binaries, and instructions on building them.
-
-** Windows (MSVC, Cygwin, and MinGW):
-
- Work on Windows is rather preliminary: we haven't found a good way
- to get stack traces in release mode on windows (that is, when FPO
- is enabled), so the heap profiling may not be reliable in that
- case. Also, heap-checking and CPU profiling do not yet work at
- all. But as in other ports, the basic tcmalloc library
- functionality, overriding malloc and new and such (and even
- windows-specific functions like _aligned_malloc!), is working fine,
- at least with VC++ 7.1 (Visual Studio 2003) through VC++ 10.0,
- in both debug and release modes. See README.windows for
- instructions on how to install on Windows using Visual Studio.
-
- Cygwin can compile some but not all of perftools. Furthermore,
- there is a problem with exception-unwinding in cygwin (it can call
- malloc, which can call the exception-unwinding-setup code, which
- can lead to an infinite loop). I've comitted a workaround to the
- exception unwinding problem, but it only works in debug mode and
- when statically linking in tcmalloc. I hope to have a more proper
- fix in a later release. To configure under cygwin, run
-
- ./configure --disable-shared CXXFLAGS=-g && make
-
- Most of cygwin will compile (cygwin doesn't allow weak symbols, so
- the heap-checker and a few other pieces of functionality will not
- compile). 'make' will compile those libraries and tests that can
- be compiled. You can run 'make check' to make sure the basic
- functionality is working. I've heard reports that some versions of
- cygwin fail calls to pthread_join() with EINVAL, causing several
- tests to fail. If you have any insight into this, please mail
- google-perftools@googlegroups.com.
-
- This Windows functionality is also available using MinGW and Msys,
- In this case, you can use the regular './configure && make'
- process. 'make install' should also work. The Makefile will limit
- itself to those libraries and binaries that work on windows.
-
-
-Basic Installation
-==================
-
- These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
- It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring. (Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.)
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
- The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'. You only need
-`configure.ac' if you want to change it or regenerate `configure' using
-a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. Run `./configure --help'
-for details on some of the pertinent environment variables.
-
- You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment. Here
-is an example:
-
- ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
-
- *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not support the `VPATH'
-variable, you have to compile the package for one architecture at a
-time in the source code directory. After you have installed the
-package for one architecture, use `make distclean' before reconfiguring
-for another architecture.
-
-Installation Names
-==================
-
- By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc. You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on. Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
- CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
- OS KERNEL-OS
-
- See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
- If you are _building_ compiler tools for cross-compiling, you should
-use the `--target=TYPE' option to select the type of system they will
-produce code for.
-
- If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
- Variables not defined in a site shell script can be set in the
-environment passed to `configure'. However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost. In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'. For example:
-
- ./configure CC=/usr/local2/bin/gcc
-
-will cause the specified gcc to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-`configure' Invocation
-======================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--version'
-`-V'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`--cache-file=FILE'
- Enable the cache: use and save the results of the tests in FILE,
- traditionally `config.cache'. FILE defaults to `/dev/null' to
- disable caching.
-
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-# serial 5 lt~obsolete.m4
-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else. This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-// A fast map from addresses to values. Assumes that addresses are
-// clustered. The main use is intended to be for heap-profiling.
-// May be too memory-hungry for other uses.
-//
-// We use a user-defined allocator/de-allocator so that we can use
-// this data structure during heap-profiling.
-//
-// IMPLEMENTATION DETAIL:
-//
-// Some default definitions/parameters:
-// * Block -- aligned 128-byte region of the address space
-// * Cluster -- aligned 1-MB region of the address space
-// * Block-ID -- block-number within a cluster
-// * Cluster-ID -- Starting address of cluster divided by cluster size
-//
-// We use a three-level map to represent the state:
-// 1. A hash-table maps from a cluster-ID to the data for that cluster.
-// 2. For each non-empty cluster we keep an array indexed by
-// block-ID tht points to the first entry in the linked-list
-// for the block.
-// 3. At the bottom, we keep a singly-linked list of all
-// entries in a block (for non-empty blocks).
-//
-// hash table
-// +-------------+
-// | id->cluster |---> ...
-// | ... |
-// | id->cluster |---> Cluster
-// +-------------+ +-------+ Data for one block
-// | nil | +------------------------------------+
-// | ----+---|->[addr/value]-->[addr/value]-->... |
-// | nil | +------------------------------------+
-// | ----+--> ...
-// | nil |
-// | ... |
-// +-------+
-//
-// Note that we require zero-bytes of overhead for completely empty
-// clusters. The minimum space requirement for a cluster is the size
-// of the hash-table entry plus a pointer value for each block in
-// the cluster. Empty blocks impose no extra space requirement.
-//
-// The cost of a lookup is:
-// a. A hash-table lookup to find the cluster
-// b. An array access in the cluster structure
-// c. A traversal over the linked-list for a block

-//
-// Used to override malloc routines on OS X systems. We use the
-// malloc-zone functionality built into OS X to register our malloc
-// routine.
-//
-// 1) We used to use the normal 'override weak libc malloc/etc'
-// technique for OS X. This is not optimal because mach does not
-// support the 'alias' attribute, so we had to have forwarding
-// functions. It also does not work very well with OS X shared
-// libraries (dylibs) -- in general, the shared libs don't use
-// tcmalloc unless run with the DYLD_FORCE_FLAT_NAMESPACE envvar.
-//
-// 2) Another approach would be to use an interposition array:
-// static const interpose_t interposers[] __attribute__((section("__DATA, __interpose"))) = {
-// { (void *)tc_malloc, (void *)malloc },
-// { (void *)tc_free, (void *)free },
-// };
-// This requires the user to set the DYLD_INSERT_LIBRARIES envvar, so
-// is not much better.
-//
-// 3) Registering a new malloc zone avoids all these issues:
-// http://www.opensource.apple.com/source/Libc/Libc-583/include/malloc/malloc.h
-// http://www.opensource.apple.com/source/Libc/Libc-583/gen/malloc.c
-// If we make tcmalloc the default malloc zone (undocumented but
-// possible) then all new allocs use it, even those in shared
-// libraries. Allocs done before tcmalloc was installed, or in libs
-// that aren't using tcmalloc for some reason, will correctly go
-// through the malloc-zone interface when free-ing, and will pick up
-// the libc free rather than tcmalloc free. So it should "never"
-// cause a crash (famous last words).
-//
-// 4) The routines one must define for one's own malloc have changed
-// between OS X versions. This requires some hoops on our part, but
-// is only really annoying when it comes to posix_memalign. The right
-// behavior there depends on what OS version tcmalloc was compiled on,
-// but also what OS version the program is running on. For now, we
-// punt and don't implement our own posix_memalign. Apps that really
-// care can use tc_posix_memalign directly.

-// Some of our malloc implementations can invoke the following hooks whenever
-// memory is allocated or deallocated. MallocHook is thread-safe, and things
-// you do before calling AddFooHook(MyHook) are visible to any resulting calls
-// to MyHook. Hooks must be thread-safe. If you write:
-//
-// CHECK(MallocHook::AddNewHook(&MyNewHook));
-//
-// MyNewHook will be invoked in subsequent calls in the current thread, but
-// there are no guarantees on when it might be invoked in other threads.
-//
-// There are a limited number of slots available for each hook type. Add*Hook
-// will return false if there are no slots available. Remove*Hook will return
-// false if the given hook was not already installed.
-//
-// The order in which individual hooks are called in Invoke*Hook is undefined.
-//
-// It is safe for a hook to remove itself within Invoke*Hook and add other
-// hooks. Any hooks added inside a hook invocation (for the same hook type)
-// will not be invoked for the current invocation.
-//
-// One important user of these hooks is the heap profiler.
-//
-// CAVEAT: If you add new MallocHook::Invoke* calls then those calls must be
-// directly in the code of the (de)allocation function that is provided to the
-// user and that function must have an ATTRIBUTE_SECTION(malloc_hook) attribute.
-//
-// Note: the Invoke*Hook() functions are defined in malloc_hook-inl.h. If you
-// need to invoke a hook (which you shouldn't unless you're part of tcmalloc),
-// be sure to #include malloc_hook-inl.h in addition to malloc_hook.h.

-// Unittest for the TCMalloc implementation.
-//
-// * The test consists of a set of threads.
-// * Each thread maintains a set of allocated objects, with
-// a bound on the total amount of data in the set.
-// * Each allocated object's contents are generated by
-// hashing the object pointer, and a generation count
-// in the object. This allows us to easily check for
-// data corruption.
-// * At any given step, the thread can do any of the following:
-// a. Allocate an object
-// b. Increment an object's generation count and update
-// its contents.
-// c. Pass the object to another thread
-// d. Free an object
-// Also, at the end of every step, object(s) are freed to maintain
-// the memory upper-bound.
-//
-// If this test is compiled with -DDEBUGALLOCATION, then we don't
-// run some tests that test the inner workings of tcmalloc and
-// break on debugallocation: that certain allocations are aligned
-// in a certain way (even though no standard requires it), and that
-// realloc() tries to minimize copying (which debug allocators don't
-// care about).

-// Produce stack trace.
-//
-// There are three different ways we can try to get the stack trace:
-//
-// 1) Our hand-coded stack-unwinder. This depends on a certain stack
-// layout, which is used by gcc (and those systems using a
-// gcc-compatible ABI) on x86 systems, at least since gcc 2.95.
-// It uses the frame pointer to do its work.
-//
-// 2) The libunwind library. This is still in development, and as a
-// separate library adds a new dependency, abut doesn't need a frame
-// pointer. It also doesn't call malloc.
-//
-// 3) The gdb unwinder -- also the one used by the c++ exception code.
-// It's obviously well-tested, but has a fatal flaw: it can call
-// malloc() from the unwinder. This is a problem because we're
-// trying to use the unwinder to instrument malloc().
-//
-// Note: if you add a new implementation here, make sure it works
-// correctly when GetStackTrace() is called with max_depth == 0.
-// Some code may do that.

-// Produces a stack trace for Windows. Normally, one could use
-// stacktrace_x86-inl.h or stacktrace_x86_64-inl.h -- and indeed, that
-// should work for binaries compiled using MSVC in "debug" mode.
-// However, in "release" mode, Windows uses frame-pointer
-// optimization, which makes getting a stack trace very difficult.
-//
-// There are several approaches one can take. One is to use Windows
-// intrinsics like StackWalk64. These can work, but have restrictions
-// on how successful they can be. Another attempt is to write a
-// version of stacktrace_x86-inl.h that has heuristic support for
-// dealing with FPO, similar to what WinDbg does (see
-// http://www.nynaeve.net/?p=97).
-//
-// The solution we've ended up doing is to call the undocumented
-// windows function RtlCaptureStackBackTrace, which probably doesn't
-// work with FPO but at least is fast, and doesn't require a symbol
-// server.

-<h1>TCMalloc : Thread-Caching Malloc</h1>
-
-<address>Sanjay Ghemawat</address>
-
-<h2><A name=motivation>Motivation</A></h2>
-
-<p>TCMalloc is faster than the glibc 2.3 malloc (available as a
-separate library called ptmalloc2) and other mallocs that I have
-tested. ptmalloc2 takes approximately 300 nanoseconds to execute a
-malloc/free pair on a 2.8 GHz P4 (for small objects). The TCMalloc
-implementation takes approximately 50 nanoseconds for the same
-operation pair. Speed is important for a malloc implementation
-because if malloc is not fast enough, application writers are inclined
-to write their own custom free lists on top of malloc. This can lead
-to extra complexity, and more memory usage unless the application
-writer is very careful to appropriately size the free lists and
-scavenge idle objects out of the free list.</p>
-
-<p>TCMalloc also reduces lock contention for multi-threaded programs.
-For small objects, there is virtually zero contention. For large
-objects, TCMalloc tries to use fine grained and efficient spinlocks.
-ptmalloc2 also reduces lock contention by using per-thread arenas but
-there is a big problem with ptmalloc2's use of per-thread arenas. In
-ptmalloc2 memory can never move from one arena to another. This can
-lead to huge amounts of wasted space. For example, in one Google
-application, the first phase would allocate approximately 300MB of
-memory for its URL canonicalization data structures. When the first
-phase finished, a second phase would be started in the same address
-space. If this second phase was assigned a different arena than the
-one used by the first phase, this phase would not reuse any of the
-memory left after the first phase and would add another 300MB to the
-address space. Similar memory blowup problems were also noticed in
-other applications.</p>
-
-<p>Another benefit of TCMalloc is space-efficient representation of
-small objects. For example, N 8-byte objects can be allocated while
-using space approximately <code>8N * 1.01</code> bytes. I.e., a
-one-percent space overhead. ptmalloc2 uses a four-byte header for
-each object and (I think) rounds up the size to a multiple of 8 bytes
-and ends up using <code>16N</code> bytes.</p>
-
-
-<h2><A NAME="Usage">Usage</A></h2>
-
-<p>To use TCMalloc, just link TCMalloc into your application via the
-"-ltcmalloc" linker flag.</p>
-
-<p>You can use TCMalloc in applications you didn't compile yourself,
-by using LD_PRELOAD:</p>
-<pre>
- $ LD_PRELOAD="/usr/lib/libtcmalloc.so" <binary>
-</pre>
-<p>LD_PRELOAD is tricky, and we don't necessarily recommend this mode
-of usage.</p>
-
-<p>TCMalloc includes a <A HREF="heap_checker.html">heap checker</A>
-and <A HREF="heapprofile.html">heap profiler</A> as well.</p>
-
-<p>If you'd rather link in a version of TCMalloc that does not include
-the heap profiler and checker (perhaps to reduce binary size for a
-static binary), you can link in <code>libtcmalloc_minimal</code>
-instead.</p>
-
-
-<h2><A NAME="Overview">Overview</A></h2>
-
-<p>TCMalloc assigns each thread a thread-local cache. Small
-allocations are satisfied from the thread-local cache. Objects are
-moved from central data structures into a thread-local cache as
-needed, and periodic garbage collections are used to migrate memory
-back from a thread-local cache into the central data structures.</p>
-<center><img src="overview.gif"></center>
-
-<p>TCMalloc treats objects with size <= 256K ("small" objects)
-differently from larger objects. Large objects are allocated directly
-from the central heap using a page-level allocator (a page is a 8K
-aligned region of memory). I.e., a large object is always
-page-aligned and occupies an integral number of pages.</p>
-
-<p>A run of pages can be carved up into a sequence of small objects,
-each equally sized. For example a run of one page (4K) can be carved
-up into 32 objects of size 128 bytes each.</p>
-
-
-<h2><A NAME="Small_Object_Allocation">Small Object Allocation</A></h2>
-
-<p>Each small object size maps to one of approximately 88 allocatable
-size-classes. For example, all allocations in the range 961 to 1024
-bytes are rounded up to 1024. The size-classes are spaced so that
-small sizes are separated by 8 bytes, larger sizes by 16 bytes, even
-larger sizes by 32 bytes, and so forth. The maximal spacing is
-controlled so that not too much space is wasted when an allocation
-request falls just past the end of a size class and has to be rounded
-up to the next class.</p>
-
-<p>A thread cache contains a singly linked list of free objects per
-size-class.</p>
-<center><img src="threadheap.gif"></center>
-
-<p>When allocating a small object: (1) We map its size to the
-corresponding size-class. (2) Look in the corresponding free list in
-the thread cache for the current thread. (3) If the free list is not
-empty, we remove the first object from the list and return it. When
-following this fast path, TCMalloc acquires no locks at all. This
-helps speed-up allocation significantly because a lock/unlock pair
-takes approximately 100 nanoseconds on a 2.8 GHz Xeon.</p>
-
-<p>If the free list is empty: (1) We fetch a bunch of objects from a
-central free list for this size-class (the central free list is shared
-by all threads). (2) Place them in the thread-local free list. (3)
-Return one of the newly fetched objects to the applications.</p>
-
-<p>If the central free list is also empty: (1) We allocate a run of
-pages from the central page allocator. (2) Split the run into a set
-of objects of this size-class. (3) Place the new objects on the
-central free list. (4) As before, move some of these objects to the
-thread-local free list.</p>
-
-<h3><A NAME="Sizing_Thread_Cache_Free_Lists">
- Sizing Thread Cache Free Lists</A></h3>
-
-<p>It is important to size the thread cache free lists correctly. If
-the free list is too small, we'll need to go to the central free list
-too often. If the free list is too big, we'll waste memory as objects
-sit idle in the free list.</p>
-
-<p>Note that the thread caches are just as important for deallocation
-as they are for allocation. Without a cache, each deallocation would
-require moving the memory to the central free list. Also, some threads
-have asymmetric alloc/free behavior (e.g. producer and consumer threads),
-so sizing the free list correctly gets trickier.</p>
-
-<p>To size the free lists appropriately, we use a slow-start algorithm
-to determine the maximum length of each individual free list. As the
-free list is used more frequently, its maximum length grows. However,
-if a free list is used more for deallocation than allocation, its
-maximum length will grow only up to a point where the whole list can
-be efficiently moved to the central free list at once.</p>
-
-<p>The psuedo-code below illustrates this slow-start algorithm. Note
-that <code>num_objects_to_move</code> is specific to each size class.
-By moving a list of objects with a well-known length, the central
-cache can efficiently pass these lists between thread caches. If
-a thread cache wants fewer than <code>num_objects_to_move</code>,
-the operation on the central free list has linear time complexity.
-The downside of always using <code>num_objects_to_move</code> as
-the number of objects to transfer to and from the central cache is
-that it wastes memory in threads that don't need all of those objects.
-
-<pre>
-Start each freelist max_length at 1.
-
-Allocation
- if freelist empty {
- fetch min(max_length, num_objects_to_move) from central list;
- if max_length < num_objects_to_move { // slow-start
- max_length++;
- } else {
- max_length += num_objects_to_move;
- }
- }
-
-Deallocation
- if length > max_length {
- // Don't try to release num_objects_to_move if we don't have that many.
- release min(max_length, num_objects_to_move) objects to central list
- if max_length < num_objects_to_move {
- // Slow-start up to num_objects_to_move.
- max_length++;
- } else if max_length > num_objects_to_move {
- // If we consistently go over max_length, shrink max_length.
- overages++;
- if overages > kMaxOverages {
- max_length -= num_objects_to_move;
- overages = 0;
- }
- }
- }
-</pre>
-
-See also the section on <a href="#Garbage_Collection">Garbage Collection</a>
-to see how it affects the <code>max_length</code>.
-
-<h2><A NAME="Large_Object_Allocation">Large Object Allocation</A></h2>
-
-<p>A large object size (> 256K) is rounded up to a page size (8K)
-and is handled by a central page heap. The central page heap is again
-an array of free lists. For <code>i < 128</code>, the
-<code>k</code>th entry is a free list of runs that consist of
-<code>k</code> pages. The <code>128</code>th entry is a free list of
-runs that have length <code>>= 128</code> pages: </p>
-<center><img src="pageheap.gif"></center>
-
-<p>An allocation for <code>k</code> pages is satisfied by looking in
-the <code>k</code>th free list. If that free list is empty, we look
-in the next free list, and so forth. Eventually, we look in the last
-free list if necessary. If that fails, we fetch memory from the
-system (using <code>sbrk</code>, <code>mmap</code>, or by mapping in
-portions of <code>/dev/mem</code>).</p>
-
-<p>If an allocation for <code>k</code> pages is satisfied by a run
-of pages of length > <code>k</code>, the remainder of the
-run is re-inserted back into the appropriate free list in the
-page heap.</p>
-
-
-<h2><A NAME="Spans">Spans</A></h2>
-
-<p>The heap managed by TCMalloc consists of a set of pages. A run of
-contiguous pages is represented by a <code>Span</code> object. A span
-can either be <em>allocated</em>, or <em>free</em>. If free, the span
-is one of the entries in a page heap linked-list. If allocated, it is
-either a large object that has been handed off to the application, or
-a run of pages that have been split up into a sequence of small
-objects. If split into small objects, the size-class of the objects
-is recorded in the span.</p>
-
-<p>A central array indexed by page number can be used to find the span to
-which a page belongs. For example, span <em>a</em> below occupies 2
-pages, span <em>b</em> occupies 1 page, span <em>c</em> occupies 5
-pages and span <em>d</em> occupies 3 pages.</p>
-<center><img src="spanmap.gif"></center>
-
-<p>In a 32-bit address space, the central array is represented by a a
-2-level radix tree where the root contains 32 entries and each leaf
-contains 2^14 entries (a 32-bit address space has 2^19 8K pages, and
-the first level of tree divides the 2^19 pages by 2^5). This leads to
-a starting memory usage of 64KB of space (2^14*4 bytes) for the
-central array, which seems acceptable.</p>
-
-<p>On 64-bit machines, we use a 3-level radix tree.</p>
-
-
-<h2><A NAME="Deallocation">Deallocation</A></h2>
-
-<p>When an object is deallocated, we compute its page number and look
-it up in the central array to find the corresponding span object. The
-span tells us whether or not the object is small, and its size-class
-if it is small. If the object is small, we insert it into the
-appropriate free list in the current thread's thread cache. If the
-thread cache now exceeds a predetermined size (2MB by default), we run
-a garbage collector that moves unused objects from the thread cache
-into central free lists.</p>
-
-<p>If the object is large, the span tells us the range of pages covered
-by the object. Suppose this range is <code>[p,q]</code>. We also
-lookup the spans for pages <code>p-1</code> and <code>q+1</code>. If
-either of these neighboring spans are free, we coalesce them with the
-<code>[p,q]</code> span. The resulting span is inserted into the
-appropriate free list in the page heap.</p>
-
-
-<h2>Central Free Lists for Small Objects</h2>
-
-<p>As mentioned before, we keep a central free list for each
-size-class. Each central free list is organized as a two-level data
-structure: a set of spans, and a linked list of free objects per
-span.</p>
-
-<p>An object is allocated from a central free list by removing the
-first entry from the linked list of some span. (If all spans have
-empty linked lists, a suitably sized span is first allocated from the
-central page heap.)</p>
-
-<p>An object is returned to a central free list by adding it to the
-linked list of its containing span. If the linked list length now
-equals the total number of small objects in the span, this span is now
-completely free and is returned to the page heap.</p>
-
-
-<h2><A NAME="Garbage_Collection">Garbage Collection of Thread Caches</A></h2>
-
-<p>Garbage collecting objects from a thread cache keeps the size of
-the cache under control and returns unused objects to the central free
-lists. Some threads need large caches to perform well while others
-can get by with little or no cache at all. When a thread cache goes
-over its <code>max_size</code>, garbage collection kicks in and then the
-thread competes with the other threads for a larger cache.</p>
-
-<p>Garbage collection is run only during a deallocation. We walk over
-all free lists in the cache and move some number of objects from the
-free list to the corresponding central list.</p>
-
-<p>The number of objects to be moved from a free list is determined
-using a per-list low-water-mark <code>L</code>. <code>L</code>
-records the minimum length of the list since the last garbage
-collection. Note that we could have shortened the list by
-<code>L</code> objects at the last garbage collection without
-requiring any extra accesses to the central list. We use this past
-history as a predictor of future accesses and move <code>L/2</code>
-objects from the thread cache free list to the corresponding central
-free list. This algorithm has the nice property that if a thread
-stops using a particular size, all objects of that size will quickly
-move from the thread cache to the central free list where they can be
-used by other threads.</p>
-
-<p>If a thread consistently deallocates more objects of a certain size
-than it allocates, this <code>L/2</code> behavior will cause at least
-<code>L/2</code> objects to always sit in the free list. To avoid
-wasting memory this way, we shrink the maximum length of the freelist
-to converge on <code>num_objects_to_move</code> (see also
-<a href="#Sizing_Thread_Cache_Free_Lists">Sizing Thread Cache Free Lists</a>).
-
-<pre>
-Garbage Collection
- if (L != 0 && max_length > num_objects_to_move) {
- max_length = max(max_length - num_objects_to_move, num_objects_to_move)
- }
-</pre>
-
-<p>The fact that the thread cache went over its <code>max_size</code> is
-an indication that the thread would benefit from a larger cache. Simply
-increasing <code>max_size</code> would use an inordinate amount of memory
-in programs that have lots of active threads. Developers can bound the
-memory used with the flag --tcmalloc_max_total_thread_cache_bytes.</p>
-
-<p>Each thread cache starts with a small <code>max_size</code>
-(e.g. 64KB) so that idle threads won't pre-allocate memory they don't
-need. Each time the cache runs a garbage collection, it will also try
-to grow its <code>max_size</code>. If the sum of the thread cache
-sizes is less than --tcmalloc_max_total_thread_cache_bytes,
-<code>max_size</code> grows easily. If not, thread cache 1 will try
-to steal from thread cache 2 (picked round-robin) by decreasing thread
-cache 2's <code>max_size</code>. In this way, threads that are more
-active will steal memory from other threads more often than they are
-have memory stolen from themselves. Mostly idle threads end up with
-small caches and active threads end up with big caches. Note that
-this stealing can cause the sum of the thread cache sizes to be
-greater than --tcmalloc_max_total_thread_cache_bytes until thread
-cache 2 deallocates some memory to trigger a garbage collection.</p>
-
-<h2><A NAME="performance">Performance Notes</A></h2>
-
-<h3>PTMalloc2 unittest</h3>
-
-<p>The PTMalloc2 package (now part of glibc) contains a unittest
-program <code>t-test1.c</code>. This forks a number of threads and
-performs a series of allocations and deallocations in each thread; the
-threads do not communicate other than by synchronization in the memory
-allocator.</p>
-
-<p><code>t-test1</code> (included in
-<code>tests/tcmalloc/</code>, and compiled as
-<code>ptmalloc_unittest1</code>) was run with a varying numbers of
-threads (1-20) and maximum allocation sizes (64 bytes -
-32Kbytes). These tests were run on a 2.4GHz dual Xeon system with
-hyper-threading enabled, using Linux glibc-2.3.2 from RedHat 9, with
-one million operations per thread in each test. In each case, the test
-was run once normally, and once with
-<code>LD_PRELOAD=libtcmalloc.so</code>.
-
-<p>The graphs below show the performance of TCMalloc vs PTMalloc2 for
-several different metrics. Firstly, total operations (millions) per
-elapsed second vs max allocation size, for varying numbers of
-threads. The raw data used to generate these graphs (the output of the
-<code>time</code> utility) is available in
-<code>t-test1.times.txt</code>.</p>

- <li> TCMalloc is much more consistently scalable than PTMalloc2 - for
- all thread counts >1 it achieves ~7-9 million ops/sec for small
- allocations, falling to ~2 million ops/sec for larger
- allocations. The single-thread case is an obvious outlier,
- since it is only able to keep a single processor busy and hence
- can achieve fewer ops/sec. PTMalloc2 has a much higher variance
- on operations/sec - peaking somewhere around 4 million ops/sec
- for small allocations and falling to <1 million ops/sec for
- larger allocations.
-
- <li> TCMalloc is faster than PTMalloc2 in the vast majority of
- cases, and particularly for small allocations. Contention
- between threads is less of a problem in TCMalloc.
-
- <li> TCMalloc's performance drops off as the allocation size
- increases. This is because the per-thread cache is
- garbage-collected when it hits a threshold (defaulting to
- 2MB). With larger allocation sizes, fewer objects can be stored
- in the cache before it is garbage-collected.
-
- <li> There is a noticeable drop in TCMalloc's performance at ~32K
- maximum allocation size; at larger sizes performance drops less
- quickly. This is due to the 32K maximum size of objects in the
- per-thread caches; for objects larger than this TCMalloc
- allocates from the central page heap.

-<p>Here we see again that TCMalloc is both more consistent and more
-efficient than PTMalloc2. For max allocation sizes <32K, TCMalloc
-typically achieves ~2-2.5 million ops per second of CPU time with a
-large number of threads, whereas PTMalloc achieves generally 0.5-1
-million ops per second of CPU time, with a lot of cases achieving much
-less than this figure. Above 32K max allocation size, TCMalloc drops
-to 1-1.5 million ops per second of CPU time, and PTMalloc drops almost
-to zero for large numbers of threads (i.e. with PTMalloc, lots of CPU
-time is being burned spinning waiting for locks in the heavily
-multi-threaded case).</p>

- Bound on the total amount of bytes allocated to thread caches. This

- applications with many threads, this may not be a large enough cache,
- which can affect performance. If you suspect your application is not
- scaling to many threads due to lock contention in TCMalloc, you can
- try increasing this value. This may improve performance, at a cost
- of extra memory use by TCMalloc. See <a href="#Garbage_Collection">

-<H2><A NAME="compiletime">Modifying Behavior In Code</A></H2>
-
-<p>The <code>MallocExtension</code> class, in
-<code>malloc_extension.h</code>, provides a few knobs that you can
-tweak in your program, to affect tcmalloc's behavior.</p>
-
-<h3>Releasing Memory Back to the System</h3>
-
-<p>By default, tcmalloc will release no-longer-used memory back to the
-kernel gradually, over time. The <a
-href="#runtime">tcmalloc_release_rate</a> flag controls how quickly
-this happens. You can also force a release at a given point in the
-progam execution like so:</p>
-<pre>
- MallocExtension::instance()->ReleaseFreeMemory();
-</pre>
-
-<p>You can also call <code>SetMemoryReleaseRate()</code> to change the
-<code>tcmalloc_release_rate</code> value at runtime, or
-<code>GetMemoryReleaseRate</code> to see what the current release rate
-is.</p>
-
-<h3>Memory Introspection</h3>
-
-<p>There are several routines for getting a human-readable form of the
-current memory usage:</p>
-<pre>
- MallocExtension::instance()->GetStats(buffer, buffer_length);
- MallocExtension::instance()->GetHeapSample(&string);
- MallocExtension::instance()->GetHeapGrowthStacks(&string);
-</pre>
-
-<p>The last two create files in the same format as the heap-profiler,
-and can be passed as data files to pprof. The first is human-readable
-and is meant for debugging.</p>
-
-<h3>Generic Tcmalloc Status</h3>
-
-<p>TCMalloc has support for setting and retrieving arbitrary
-'properties':</p>
-<pre>
- MallocExtension::instance()->SetNumericProperty(property_name, value);
- MallocExtension::instance()->GetNumericProperty(property_name, &value);
-</pre>
-
-<p>It is possible for an application to set and get these properties,
-but the most useful is when a library sets the properties so the
-application can read them. Here are the properties TCMalloc defines;
-you can access them with a call like
-<code>MallocExtension::instance()->GetNumericProperty("generic.heap_size",
-&value);</code>:</p>
-
-<table frame=box rules=sides cellpadding=5 width=100%>
-
-<tr valign=top>
- <td><code>generic.current_allocated_bytes</code></td>
- <td>
- Number of bytes used by the application. This will not typically
- match the memory use reported by the OS, because it does not
- include TCMalloc overhead or memory fragmentation.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>generic.heap_size</code></td>
- <td>
- Bytes of system memory reserved by TCMalloc.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>tcmalloc.pageheap_free_bytes</code></td>
- <td>
- Number of bytes in free, mapped pages in page heap. These bytes
- can be used to fulfill allocation requests. They always count
- towards virtual memory usage, and unless the underlying memory is
- swapped out by the OS, they also count towards physical memory
- usage.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>tcmalloc.pageheap_unmapped_bytes</code></td>
- <td>
- Number of bytes in free, unmapped pages in page heap. These are
- bytes that have been released back to the OS, possibly by one of
- the MallocExtension "Release" calls. They can be used to fulfill
- allocation requests, but typically incur a page fault. They
- always count towards virtual memory usage, and depending on the
- OS, typically do not count towards physical memory usage.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>tcmalloc.slack_bytes</code></td>
- <td>
- Sum of pageheap_free_bytes and pageheap_unmapped_bytes. Provided
- for backwards compatibility only. Do not use.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>tcmalloc.max_total_thread_cache_bytes</code></td>
- <td>
- A limit to how much memory TCMalloc dedicates for small objects.
- Higher numbers trade off more memory use for -- in some situations
- -- improved efficiency.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>tcmalloc.current_total_thread_cache_bytes</code></td>
- <td>
- A measure of some of the memory TCMalloc is using (for
- small objects).
- </td>
-</tr>
-
-</table>
-
-<h2><A NAME="caveats">Caveats</A></h2>
-
-<p>For some systems, TCMalloc may not work correctly with
-applications that aren't linked against <code>libpthread.so</code> (or
-the equivalent on your OS). It should work on Linux using glibc 2.3,
-but other OS/libc combinations have not been tested.</p>
-
-<p>TCMalloc may be somewhat more memory hungry than other mallocs,
-(but tends not to have the huge blowups that can happen with other
-mallocs). In particular, at startup TCMalloc allocates approximately
-240KB of internal memory.</p>
-
-<p>Don't try to load TCMalloc into a running binary (e.g., using JNI
-in Java programs). The binary will have allocated some objects using
-the system malloc, and may try to pass them to TCMalloc for
-deallocation. TCMalloc will not be able to handle such objects.</p>

-// Author: Geoff Pike
-//
-// This file provides a minimal cache that can hold a <key, value> pair
-// with little if any wasted space. The types of the key and value
-// must be unsigned integral types or at least have unsigned semantics
-// for >>, casting, and similar operations.
-//
-// Synchronization is not provided. However, the cache is implemented
-// as an array of cache entries whose type is chosen at compile time.
-// If a[i] is atomic on your hardware for the chosen array type then
-// raciness will not necessarily lead to bugginess. The cache entries
-// must be large enough to hold a partial key and a value packed
-// together. The partial keys are bit strings of length
-// kKeybits - kHashbits, and the values are bit strings of length kValuebits.
-//
-// In an effort to use minimal space, every cache entry represents
-// some <key, value> pair; the class provides no way to mark a cache
-// entry as empty or uninitialized. In practice, you may want to have
-// reserved keys or values to get around this limitation. For example, in
-// tcmalloc's PageID-to-sizeclass cache, a value of 0 is used as
-// "unknown sizeclass."
-//
-// Usage Considerations
-// --------------------
-//
-// kHashbits controls the size of the cache. The best value for
-// kHashbits will of course depend on the application. Perhaps try
-// tuning the value of kHashbits by measuring different values on your
-// favorite benchmark. Also remember not to be a pig; other
-// programs that need resources may suffer if you are.
-//
-// The main uses for this class will be when performance is
-// critical and there's a convenient type to hold the cache's
-// entries. As described above, the number of bits required
-// for a cache entry is (kKeybits - kHashbits) + kValuebits. Suppose
-// kKeybits + kValuebits is 43. Then it probably makes sense to
-// chose kHashbits >= 11 so that cache entries fit in a uint32.
-//
-// On the other hand, suppose kKeybits = kValuebits = 64. Then
-// using this class may be less worthwhile. You'll probably
-// be using 128 bits for each entry anyway, so maybe just pick
-// a hash function, H, and use an array indexed by H(key):
-// void Put(K key, V value) { a_[H(key)] = pair<K, V>(key, value); }
-// V GetOrDefault(K key, V default) { const pair<K, V> &p = a_[H(key)]; ... }
-// etc.
-//
-// Further Details
-// ---------------
-//
-// For caches used only by one thread, the following is true:
-// 1. For a cache c,
-// (c.Put(key, value), c.GetOrDefault(key, 0)) == value
-// and
-// (c.Put(key, value), <...>, c.GetOrDefault(key, 0)) == value
-// if the elided code contains no c.Put calls.
-//
-// 2. Has(key) will return false if no <key, value> pair with that key
-// has ever been Put. However, a newly initialized cache will have
-// some <key, value> pairs already present. When you create a new
-// cache, you must specify an "initial value." The initialization
-// procedure is equivalent to Clear(initial_value), which is
-// equivalent to Put(k, initial_value) for all keys k from 0 to
-// 2^kHashbits - 1.
-//
-// 3. If key and key' differ then the only way Put(key, value) may
-// cause Has(key') to change is that Has(key') may change from true to
-// false. Furthermore, a Put() call that doesn't change Has(key')
-// doesn't change GetOrDefault(key', ...) either.
-//
-// Implementation details:
-//
-// This is a direct-mapped cache with 2^kHashbits entries; the hash
-// function simply takes the low bits of the key. We store whole keys
-// if a whole key plus a whole value fits in an entry. Otherwise, an
-// entry is the high bits of a key and a value, packed together.
-// E.g., a 20 bit key and a 7 bit value only require a uint16 for each
-// entry if kHashbits >= 11.
-//
-// Alternatives to this scheme will be added as needed.

-\`configure' configures gperftools 2.4 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]

- --enable-stacktrace-via-backtrace
- enable use of backtrace() for stacktrace capturing
- (may deadlock)
- --enable-libunwind enable libunwind linking
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]

-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-tcmalloc-pagesize
- Set the tcmalloc internal page size to 8K, 32K or
- 64K
- --with-tcmalloc-alignment
- Set the tcmalloc allocation alignment to 8 or 16
- bytes
- --with-pic[=PKGS] try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
- --with-sysroot=DIR Search for dependent libraries within DIR
- (or the compiler's sysroot if not specified).
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CXX C++ compiler command
- CXXFLAGS C++ compiler flags
- CPP C preprocessor
- CXXCPP C++ preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-/* This file includes Linux-specific support functions common to the
- * coredumper and the thread lister; primarily, this is a collection
- * of direct system calls, and a couple of symbols missing from
- * standard header files.
- * There are a few options that the including file can set to control
- * the behavior of this file:
- *
- * SYS_CPLUSPLUS:
- * The entire header file will normally be wrapped in 'extern "C" { }",
- * making it suitable for compilation as both C and C++ source. If you
- * do not want to do this, you can set the SYS_CPLUSPLUS macro to inhibit
- * the wrapping. N.B. doing so will suppress inclusion of all prerequisite
- * system header files, too. It is the caller's responsibility to provide
- * the necessary definitions.
- *
- * SYS_ERRNO:
- * All system calls will update "errno" unless overriden by setting the
- * SYS_ERRNO macro prior to including this file. SYS_ERRNO should be
- * an l-value.
- *
- * SYS_INLINE:
- * New symbols will be defined "static inline", unless overridden by
- * the SYS_INLINE macro.
- *
- * SYS_LINUX_SYSCALL_SUPPORT_H
- * This macro is used to avoid multiple inclusions of this header file.
- * If you need to include this file more than once, make sure to
- * unset SYS_LINUX_SYSCALL_SUPPORT_H before each inclusion.
- *
- * SYS_PREFIX:
- * New system calls will have a prefix of "sys_" unless overridden by
- * the SYS_PREFIX macro. Valid values for this macro are [0..9] which
- * results in prefixes "sys[0..9]_". It is also possible to set this
- * macro to -1, which avoids all prefixes.
- *
- * This file defines a few internal symbols that all start with "LSS_".
- * Do not access these symbols from outside this file. They are not part
- * of the supported API.
- *
- * NOTE: This is a stripped down version of the official opensource
- * version of linux_syscall_support.h, which lives at
- * http://code.google.com/p/linux-syscall-support/
- * It includes only the syscalls that are used in perftools, plus a
- * few extra. Here's the breakdown:
- * 1) Perftools uses these: grep -rho 'sys_[a-z0-9_A-Z]* *(' src | sort -u
- * sys__exit(
- * sys_clone(
- * sys_close(
- * sys_fcntl(
- * sys_fstat(
- * sys_futex(
- * sys_futex1(
- * sys_getcpu(
- * sys_getdents64(
- * sys_getppid(
- * sys_gettid(
- * sys_lseek(
- * sys_mmap(
- * sys_mremap(
- * sys_munmap(
- * sys_open(
- * sys_pipe(
- * sys_prctl(
- * sys_ptrace(
- * sys_ptrace_detach(
- * sys_read(
- * sys_sched_yield(
- * sys_sigaction(
- * sys_sigaltstack(
- * sys_sigdelset(
- * sys_sigfillset(
- * sys_sigprocmask(
- * sys_socket(
- * sys_stat(
- * sys_waitpid(
- * 2) These are used as subroutines of the above:
- * sys_getpid -- gettid
- * sys_kill -- ptrace_detach
- * sys_restore -- sigaction
- * sys_restore_rt -- sigaction
- * sys_socketcall -- socket
- * sys_wait4 -- waitpid
- * 3) I left these in even though they're not used. They either
- * complement the above (write vs read) or are variants (rt_sigaction):
- * sys_fstat64
- * sys_llseek
- * sys_mmap2
- * sys_openat
- * sys_getdents
- * sys_rt_sigaction
- * sys_rt_sigprocmask
- * sys_sigaddset
- * sys_sigemptyset
- * sys_stat64
- * sys_write

-/* As glibc often provides subtly incompatible data structures (and implicit

- * These structures have been developed by using Linux 2.6.23 headers for

- * with the kernel, and in fact the kernel often does not have a single
- * API that works across architectures. Instead, we try to mimic the glibc
- * API where reasonable, and only guarantee ABI compatibility with the
- * kernel headers.
- * Most notably, here are a few changes that were made to the structures
- * defined by kernel headers:
- *
- * - we only define structures, but not symbolic names for kernel data
- * types. For the latter, we directly use the native C datatype
- * (i.e. "unsigned" instead of "mode_t").
- * - in a few cases, it is possible to define identical structures for
- * both 32bit (e.g. i386) and 64bit (e.g. x86-64) platforms by
- * standardizing on the 64bit version of the data types. In particular,
- * this means that we use "unsigned" where the 32bit headers say
- * "unsigned long".
- * - overall, we try to minimize the number of cases where we need to
- * conditionally define different structures.
- * - the "struct kernel_sigaction" class of structures have been
- * modified to more closely mimic glibc's API by introducing an
- * anonymous union for the function pointer.
- * - a small number of field names had to have an underscore appended to
- * them, because glibc defines a global macro by the same name.

- * Module for CPU profiling based on periodic pc-sampling.
- *
- * For full(er) information, see doc/cpuprofile.html
- *
- * This module is linked into your program with
- * no slowdown caused by this unless you activate the profiler
- * using one of the following methods:
- *
- * 1. Before starting the program, set the environment variable
- * "CPUPROFILE" to be the name of the file to which the profile
- * data should be written.
- *
- * 2. Programmatically, start and stop the profiler using the
- * routines "ProfilerStart(filename)" and "ProfilerStop()".
- *
- *
- * (Note: if using linux 2.4 or earlier, only the main thread may be
- * profiled.)
- *
- * Use pprof to view the resulting profile output.
- * % pprof <path_to_executable> <profile_file_name>
- * % pprof --gv <path_to_executable> <profile_file_name>
- *
- * These functions are thread-safe.

-gperftools 2.4rc is out!
-
-Here are changes since 2.3:
-
-* enabled aggressive decommit option by default. It was found to
- significantly improve memory fragmentation with negligible impact on
- performance. (Thanks to investigation work performed by Adhemerval
- Zanella)
-
-* added ./configure flags for tcmalloc pagesize and tcmalloc
- allocation alignment. Larger page sizes have been reported to
- improve performance occasionally. (Patch by Raphael Moreira Zinsly)
-
-* sped-up hot-path of malloc/free. By about 5% on static library and
- about 10% on shared library. Mainly due to more efficient checking
- of malloc hooks.
-
-* improved stacktrace capturing in cpu profiler (due to issue found by
- Arun Sharma). As part of that issue pprof's handling of cpu profiles
- was also improved.

-
-Most small improvements in this release were made to pprof tool.
-
-New experimental Linux-only (for now) cpu profiling mode is a notable
-big improvement.
-
-Here are notable changes since 2.2.1:
-
-* (issue-631) fixed debugallocation miscompilation on mmap-less
- platforms (courtesy of user iamxujian)
-
-* (issue-630) reference to wrong PROFILE (vs. correct CPUPROFILE)
- environment variable was fixed (courtesy of WenSheng He)

-
-* (issue-635) pprof now handles library paths that contain spaces
- (courtesy of user mich...@sebesbefut.com)
-
-* (issue-637) pprof now has an option to not strip template arguments
- (patch by jiakai)
-
-* (issue-644) possible out-of-bounds access in GetenvBeforeMain was
- fixed (thanks to user abyss.7)
-
-* (issue-641) pprof now has an option --show_addresses (thanks to user
- yurivict). New option prints instruction address in addition to

- proposed by user zndmitry)
-
-* incorrect detection of arm 6zk instruction set support
- (-mcpu=arm1176jzf-s) was fixed. (Reported by pedronavf on old
- issue-493)
-
-* new cpu profiling mode on Linux is now implemented. It sets up
- separate profiling timers for separate threads. Which improves
- accuracy of profiling on Linux a lot. It is off by default. And is
- enabled if both librt.f is loaded and CPUPROFILE_PER_THREAD_TIMERS
- environment variable is set. But note that all threads need to be
- registered via ProfilerRegisterThread.

-
-Here's list of fixes:
-

- fixes.
-
-* we now have mips and mips64 support! (courtesy of Jovan Zelincevic,
- Jean Lee, user xiaoyur347 and others)
-
-* we now have aarch64 (aka arm64) support! (contributed by Riku
- Voipio)
-
-* there's now support for ppc64-le (by Raphael Moreira Zinsly and
- Adhemerval Zanella)
-
-* there's now some support of uclibc (contributed by user xiaoyur347)
-
-* google/ headers will now give you deprecation warning. They are
- deprecated since 2.0
-
-* there's now new api: tc_malloc_skip_new_handler (ported from chromium
- fork)
-
-* issue-557: added support for dumping heap profile via signal (by
- Jean Lee)
-
-* issue-567: Petr Hosek contributed SysAllocator support for windows
-
-* Joonsoo Kim contributed several speedups for central freelist code
-
-* TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES environment variable now works
-
-* configure scripts are now using AM_MAINTAINER_MODE. It'll only
- affect folks who modify source from .tar.gz and want automake to
- automatically rebuild Makefile-s. See automake documentation for
- that.
-
-* issue-586: detect main executable even if PIE is active (based on
- patch by user themastermind1). Notably, it fixes profiler use with
- ruby.
-
-* there is now support for switching backtrace capturing method at
- runtime (via TCMALLOC_STACKTRACE_METHOD and
- TCMALLOC_STACKTRACE_METHOD_VERBOSE environment variables)
-
-* there is new backtrace capturing method using -finstrument-functions
- prologues contributed by user xiaoyur347
-
-* few cases of crashes/deadlocks in profiler were addressed. See
- (famous) issue-66, issue-547 and issue-579.
-
-* issue-464 (memory corruption in debugalloc's realloc after
- memallign) is now fixed
-
-* tcmalloc is now able to release memory back to OS on windows
- (issue-489). The code was ported from chromium fork (by a number of
- authors).
-
-* Together with issue-489 we ported chromium's "aggressive decommit"
- mode. In this mode (settable via malloc extension and via
- environment variable TCMALLOC_AGGRESSIVE_DECOMMIT), free pages are
- returned back to OS immediately.
-
-* MallocExtension::instance() is now faster (based on patch by
- Adhemerval Zanella)
-
-* issue-610 (hangs on windows in multibyte locales) is now fixed

-As a result of more than a year of contributions we're ready for 2.1
-release.
-
-But before making that step I'd like to create RC and make sure people
-have chance to test it.
-
-Here are notable changes since 2.0:
-
-* fixes for building on newer platforms. Notably, there's now initial
- support for x32 ABI (--enable-minimal only at this time))
-
-* new getNumericProperty stats for cache sizes
-
-* added HEAP_PROFILER_TIME_INTERVAL variable (see documentation)
-
-* added environment variable to control heap size (TCMALLOC_HEAP_LIMIT_MB)
-
-* added environment variable to disable release of memory back to OS
- (TCMALLOC_DISABLE_MEMORY_RELEASE)
-
-* cpu profiler can now be switched on and off by sending it a signal
- (specified in CPUPROFILESIGNAL)
-
-* (issue 491) fixed race-ful spinlock wake-ups
-
-* (issue 496) added some support for fork-ing of process that is using
- tcmalloc
-
-* (issue 368) improved memory fragmentation when large chunks of
- memory are allocated/freed
-
-== 03 February 2012 ==
-
-I've just released gperftools 2.0
-
-The `google-perftools` project has been renamed to `gperftools`. I
-(csilvers) am stepping down as maintainer, to be replaced by
-David Chappelle. Welcome to the team, David! David has been an
-an active contributor to perftools in the past -- in fact, he's the
-only person other than me that already has commit status. I am
-pleased to have him take over as maintainer.
-
-I have both renamed the project (the Google Code site renamed a few
-weeks ago), and bumped the major version number up to 2, to reflect
-the new community ownership of the project. Almost all the
-[http://gperftools.googlecode.com/svn/tags/gperftools-2.0/ChangeLog changes]
-are related to the renaming.
-
-The main functional change from google-perftools 1.10 is that
-I've renamed the `google/` include-directory to be `gperftools/`
-instead. New code should `#include <gperftools/tcmalloc.h>`/etc.
-(Most users of perftools don't need any perftools-specific includes at
-all, so this is mostly directed to "power users.") I've kept the old
-names around as forwarding headers to the new, so `#include
-<google/tcmalloc.h>` will continue to work.
-
-(The other functional change which I snuck in is getting rid of some
-bash-isms in one of the unittest driver scripts, so it could run on
-Solaris.)
-
-Note that some internal names still contain the text `google`, such as
-the `google_malloc` internal linker section. I think that's a
-trickier transition, and can happen in a future release (if at all).
-
-
-=== 31 January 2012 ===
-
-I've just released perftools 1.10
-
-There is an API-incompatible change: several of the methods in the
-`MallocExtension` class have changed from taking a `void*` to taking a
-`const void*`. You should not be affected by this API change
-unless you've written your own custom malloc extension that derives
-from `MallocExtension`, but since it is a user-visible change, I have
-upped the `.so` version number for this release.
-
-This release focuses on improvements to linux-syscall-support.h,
-including ARM and PPC fixups and general cleanups. I hope this will
-magically fix an array of bugs people have been seeing.
-
-There is also exciting news on the porting front, with support for
-patching win64 assembly contributed by IBM Canada! This is an
-important step -- perhaps the most difficult -- to getting perftools
-to work on 64-bit windows using the patching technique (it doesn't
-affect the libc-modification technique). `premable_patcher_test` has
-been added to help test these changes; it is meant to compile under
-x86_64, and won't work under win32.
-
-For the full list of changes, including improved `HEAP_PROFILE_MMAP`
-support, see the
-[http://gperftools.googlecode.com/svn/tags/google-perftools-1.10/ChangeLog ChangeLog].
-
-
-=== 24 January 2011 ===
-
-The `google-perftools` Google Code page has been renamed to
-`gperftools`, in preparation for the project being renamed to
-`gperftools`. In the coming weeks, I'll be stepping down as
-maintainer for the perftools project, and as part of that Google is
-relinquishing ownership of the project; it will now be entirely
-community run. The name change reflects that shift. The 'g' in
-'gperftools' stands for 'great'. :-)
-
-=== 23 December 2011 ===
-
-I've just released perftools 1.9.1
-
-I missed including a file in the tarball, that is needed to compile on
-ARM. If you are not compiling on ARM, or have successfully compiled
-perftools 1.9, there is no need to upgrade.
-
-
-=== 22 December 2011 ===
-
-I've just released perftools 1.9
-
-This change has a slew of improvements, from better ARM and freebsd
-support, to improved performance by moving some code outside of locks,
-to better pprof reporting of code with overloaded functions.
-
-The full list of changes is in the
-[http://google-perftools.googlecode.com/svn/tags/google-perftools-1.9/ChangeLog ChangeLog].
-
-
-=== 26 August 2011 ===
-
-I've just released perftools 1.8.3
-
-The star-crossed 1.8 series continues; in 1.8.1, I had accidentally
-removed some code that was needed for FreeBSD. (Without this code
-many apps would crash at startup.) This release re-adds that code.
-If you are not on FreeBSD, or are using FreeBSD with perftools 1.8 or
-earlier, there is no need to upgrade.
-
-=== 11 August 2011 ===
-
-I've just released perftools 1.8.2
-
-I was incorrectly calculating the patch-level in the configuration
-step, meaning the TC_VERSION_PATCH #define in tcmalloc.h was wrong.
-Since the testing framework checks for this, it was failing. Now it
-should work again. This time, I was careful to re-run my tests after
-upping the version number. :-)
-
-If you don't care about the TC_VERSION_PATCH #define, there's no
-reason to upgrae.
-
-=== 26 July 2011 ===
-
-I've just released perftools 1.8.1
-
-I was missing an #include that caused the build to break under some
-compilers, especially newer gcc's, that wanted it. This only affects
-people who build from source, so only the .tar.gz file is updated from
-perftools 1.8. If you didn't have any problems compiling perftools
-1.8, there's no reason to upgrade.
-
-=== 15 July 2011 ===
-
-I've just released perftools 1.8
-
-Of the many changes in this release, a good number pertain to porting.
-I've revamped OS X support to use the malloc-zone framework; it should
-now Just Work to link in tcmalloc, without needing
-`DYLD_FORCE_FLAT_NAMESPACE` or the like. (This is a pretty major
-change, so please feel free to report feedback at
-google-perftools@googlegroups.com.) 64-bit Windows support is also
-improved, as is ARM support, and the hooks are in place to improve
-FreeBSD support as well.
-
-On the other hand, I'm seeing hanging tests on Cygwin. I see the same
-hanging even with (the old) perftools 1.7, so I'm guessing this is
-either a problem specific to my Cygwin installation, or nobody is
-trying to use perftools under Cygwin. If you can reproduce the
-problem, and even better have a solution, you can report it at
-google-perftools@googlegroups.com.
-
-Internal changes include several performance and space-saving tweaks.
-One is user-visible (but in "stealth mode", and otherwise
-undocumented): you can compile with `-DTCMALLOC_SMALL_BUT_SLOW`. In
-this mode, tcmalloc will use less memory overhead, at the cost of
-running (likely not noticeably) slower.
-
-There are many other changes as well, too numerous to recount here,
-but present in the
-[http://google-perftools.googlecode.com/svn/tags/google-perftools-1.8/ChangeLog ChangeLog].
-
-
-=== 7 February 2011 ===
-
-Thanks to endlessr..., who
-[http://code.google.com/p/google-perftools/issues/detail?id=307 identified]
-why some tests were failing under MSVC 10 in release mode. It does not look
-like these failures point toward any problem with tcmalloc itself; rather, the
-problem is with the test, which made some assumptions that broke under the
-some aggressive optimizations used in MSVC 10. I'll fix the test, but in
-the meantime, feel free to use perftools even when compiled under MSVC
-10.
-
-=== 4 February 2011 ===
-
-I've just released perftools 1.7
-
-I apologize for the delay since the last release; so many great new
-patches and bugfixes kept coming in (and are still coming in; I also
-apologize to those folks who have to slip until the next release). I
-picked this arbitrary time to make a cut.
-
-Among the many new features in this release is a multi-megabyte
-reduction in the amount of tcmalloc overhead uder x86_64, improved
-performance in the case of contention, and many many bugfixes,
-especially architecture-specific bugfixes. See the
-[http://google-perftools.googlecode.com/svn/tags/google-perftools-1.7/ChangeLog ChangeLog]
-for full details.
-
-One architecture-specific change of note is added comments in the
-[http://google-perftools.googlecode.com/svn/tags/perftools-1.7/README README]
-for using tcmalloc under OS X. I'm trying to get my head around the
-exact behavior of the OS X linker, and hope to have more improvements
-for the next release, but I hope these notes help folks who have been
-having trouble with tcmalloc on OS X.
-
-*Windows users*: I've heard reports that some unittests fail on
-Windows when compiled with MSVC 10 in Release mode. All tests pass in
-Debug mode. I've not heard of any problems with earlier versions of
-MSVC. I don't know if this is a problem with the runtime patching (so
-the static patching discussed in README_windows.txt will still work),
-a problem with perftools more generally, or a bug in MSVC 10. Anyone
-with windows expertise that can debug this, I'd be glad to hear from!
-
-
-=== 5 August 2010 ===
-
-I've just released perftools 1.6
-
-This version also has a large number of minor changes, including
-support for `malloc_usable_size()` as a glibc-compatible alias to
-`malloc_size()`, the addition of SVG-based output to `pprof`, and
-experimental support for tcmalloc large pages, which may speed up
-tcmalloc at the cost of greater memory use. To use tcmalloc large
-pages, see the
-[http://google-perftools.googlecode.com/svn/tags/perftools-1.6/INSTALL
-INSTALL file]; for all changes, see the
-[http://google-perftools.googlecode.com/svn/tags/perftools-1.6/ChangeLog
-ChangeLog].
-
-OS X NOTE: improvements in the profiler unittest have turned up an OS
-X issue: in multithreaded programs, it seems that OS X often delivers
-the profiling signal (from sigitimer()) to the main thread, even when
-it's sleeping, rather than spawned threads that are doing actual work.
-If anyone knows details of how OS X handles SIGPROF events (from
-setitimer) in threaded programs, and has insight into this problem,
-please send mail to google-perftools@googlegroups.com.
-
-To see if you're affected by this, look for profiling time that pprof
-attributes to `___semwait_signal`. This is work being done in other
-threads, that is being attributed to sleeping-time in the main thread.
-
-
-=== 20 January 2010 ===
-
-I've just released perftools 1.5
-
-This version has a slew of changes, leading to somewhat faster
-performance and improvements in portability. It adds features like
-`ITIMER_REAL` support to the cpu profiler, and `tc_set_new_mode` to
-mimic the windows function of the same name. Full details are in the
-[http://google-perftools.googlecode.com/svn/tags/perftools-1.5/ChangeLog
-ChangeLog].
-
-
-=== 11 September 2009 ===
-
-I've just released perftools 1.4
-
-The major change this release is the addition of a debugging malloc
-library! If you link with `libtcmalloc_debug.so` instead of
-`libtcmalloc.so` (and likewise for the `minimal` variants) you'll get
-a debugging malloc, which will catch double-frees, writes to freed
-data, `free`/`delete` and `delete`/`delete[]` mismatches, and even
-(optionally) writes past the end of an allocated block.
-
-We plan to do more with this library in the future, including
-supporting it on Windows, and adding the ability to use the debugging
-library with your default malloc in addition to using it with
-tcmalloc.
-
-There are also the usual complement of bug fixes, documented in the
-ChangeLog, and a few minor user-tunable knobs added to components like
-the system allocator.
-
-
-=== 9 June 2009 ===
-
-I've just released perftools 1.3
-
-Like 1.2, this has a variety of bug fixes, especially related to the
-Windows build. One of my bugfixes is to undo the weird `ld -r` fix to
-`.a` files that I introduced in perftools 1.2: it caused problems on
-too many platforms. I've reverted back to normal `.a` files. To work
-around the original problem that prompted the `ld -r` fix, I now
-provide `libtcmalloc_and_profiler.a`, for folks who want to link in
-both.
-
-The most interesting API change is that I now not only override
-`malloc`/`free`/etc, I also expose them via a unique set of symbols:
-`tc_malloc`/`tc_free`/etc. This enables clients to write their own
-memory wrappers that use tcmalloc:
-{{{
- void* malloc(size_t size) { void* r = tc_malloc(size); Log(r); return r; }
-}}}
-
-
-=== 17 April 2009 ===
-
-I've just released perftools 1.2.
-
-This is mostly a bugfix release. The major change is internal: I have
-a new system for creating packages, which allows me to create 64-bit
-packages. (I still don't do that for perftools, because there is
-still no great 64-bit solution, with libunwind still giving problems
-and --disable-frame-pointers not practical in every environment.)
-
-Another interesting change involves Windows: a
-[http://code.google.com/p/google-perftools/issues/detail?id=126 new
-patch] allows users to choose to override malloc/free/etc on Windows
-rather than patching, as is done now. This can be used to create
-custom CRTs.
-
-My fix for this
-[http://groups.google.com/group/google-perftools/browse_thread/thread/1ff9b50043090d9d/a59210c4206f2060?lnk=gst&q=dynamic#a59210c4206f2060
-bug involving static linking] ended up being to make libtcmalloc.a and
-libperftools.a a big .o file, rather than a true `ar` archive. This
-should not yield any problems in practice -- in fact, it should be
-better, since the heap profiler, leak checker, and cpu profiler will
-now all work even with the static libraries -- but if you find it
-does, please file a bug report.
-
-Finally, the profile_handler_unittest provided in the perftools
-testsuite (new in this release) is failing on FreeBSD. The end-to-end
-test that uses the profile-handler is passing, so I suspect the
-problem may be with the test, not the perftools code itself. However,
-I do not know enough about how itimers work on FreeBSD to be able to
-debug it. If you can figure it out, please let me know!
-
-=== 11 March 2009 ===
-
-I've just released perftools 1.1!
-
-It has many changes since perftools 1.0 including
-
- * Faster performance due to dynamically sized thread caches
- * Better heap-sampling for more realistic profiles
- * Improved support on Windows (MSVC 7.1 and cygwin)
- * Better stacktraces in linux (using VDSO)
- * Many bug fixes and feature requests
-
-Note: if you use the CPU-profiler with applications that fork without
-doing an exec right afterwards, please see the README. Recent testing
-has shown that profiles are unreliable in that case. The problem has
-existed since the first release of perftools. We expect to have a fix
-for perftools 1.2. For more details, see
-[http://code.google.com/p/google-perftools/issues/detail?id=105 issue 105].
-
-Everyone who uses perftools 1.0 is encouraged to upgrade to perftools
-1.1. If you see any problems with the new release, please file a bug
-report at http://code.google.com/p/google-perftools/issues/list.
-
-Enjoy!

-IMPORTANT NOTE FOR 64-BIT USERS
--------------------------------
-There are known issues with some perftools functionality on x86_64
-systems. See 64-BIT ISSUES, below.
-
-
-TCMALLOC
---------
-Just link in -ltcmalloc or -ltcmalloc_minimal to get the advantages of
-tcmalloc -- a replacement for malloc and new. See below for some
-environment variables you can use with tcmalloc, as well.
-
-tcmalloc functionality is available on all systems we've tested; see
-INSTALL for more details. See README_windows.txt for instructions on
-using tcmalloc on Windows.
-
-NOTE: When compiling with programs with gcc, that you plan to link
-with libtcmalloc, it's safest to pass in the flags
-
- -fno-builtin-malloc -fno-builtin-calloc -fno-builtin-realloc -fno-builtin-free
-
-when compiling. gcc makes some optimizations assuming it is using its
-own, built-in malloc; that assumption obviously isn't true with
-tcmalloc. In practice, we haven't seen any problems with this, but
-the expected risk is highest for users who register their own malloc
-hooks with tcmalloc (using gperftools/malloc_hook.h). The risk is
-lowest for folks who use tcmalloc_minimal (or, of course, who pass in
-the above flags :-) ).
-
-
-HEAP PROFILER
--------------
-See doc/heap-profiler.html for information about how to use tcmalloc's
-heap profiler and analyze its output.
-
-As a quick-start, do the following after installing this package:
-
-1) Link your executable with -ltcmalloc
-2) Run your executable with the HEAPPROFILE environment var set:
- $ HEAPPROFILE=/tmp/heapprof <path/to/binary> [binary args]
-3) Run pprof to analyze the heap usage
- $ pprof <path/to/binary> /tmp/heapprof.0045.heap # run 'ls' to see options
- $ pprof --gv <path/to/binary> /tmp/heapprof.0045.heap
-
-You can also use LD_PRELOAD to heap-profile an executable that you
-didn't compile.
-
-There are other environment variables, besides HEAPPROFILE, you can
-set to adjust the heap-profiler behavior; c.f. "ENVIRONMENT VARIABLES"
-below.
-
-The heap profiler is available on all unix-based systems we've tested;
-see INSTALL for more details. It is not currently available on Windows.
-
-
-HEAP CHECKER
-------------
-See doc/heap-checker.html for information about how to use tcmalloc's
-heap checker.
-
-In order to catch all heap leaks, tcmalloc must be linked *last* into
-your executable. The heap checker may mischaracterize some memory
-accesses in libraries listed after it on the link line. For instance,
-it may report these libraries as leaking memory when they're not.
-(See the source code for more details.)
-
-Here's a quick-start for how to use:
-
-As a quick-start, do the following after installing this package:
-
-1) Link your executable with -ltcmalloc
-2) Run your executable with the HEAPCHECK environment var set:
- $ HEAPCHECK=1 <path/to/binary> [binary args]
-
-Other values for HEAPCHECK: normal (equivalent to "1"), strict, draconian
-
-You can also use LD_PRELOAD to heap-check an executable that you
-didn't compile.
-
-The heap checker is only available on Linux at this time; see INSTALL
-for more details.
-
-
-CPU PROFILER
-------------
-See doc/cpu-profiler.html for information about how to use the CPU
-profiler and analyze its output.
-
-As a quick-start, do the following after installing this package:
-
-1) Link your executable with -lprofiler
-2) Run your executable with the CPUPROFILE environment var set:
- $ CPUPROFILE=/tmp/prof.out <path/to/binary> [binary args]
-3) Run pprof to analyze the CPU usage
- $ pprof <path/to/binary> /tmp/prof.out # -pg-like text output
- $ pprof --gv <path/to/binary> /tmp/prof.out # really cool graphical output
-
-There are other environment variables, besides CPUPROFILE, you can set
-to adjust the cpu-profiler behavior; cf "ENVIRONMENT VARIABLES" below.
-
-The CPU profiler is available on all unix-based systems we've tested;
-see INSTALL for more details. It is not currently available on Windows.
-
-NOTE: CPU profiling doesn't work after fork (unless you immediately
- do an exec()-like call afterwards). Furthermore, if you do
- fork, and the child calls exit(), it may corrupt the profile
- data. You can use _exit() to work around this. We hope to have
- a fix for both problems in the next release of perftools
- (hopefully perftools 1.2).
-
-
-EVERYTHING IN ONE
------------------
-If you want the CPU profiler, heap profiler, and heap leak-checker to
-all be available for your application, you can do:
- gcc -o myapp ... -lprofiler -ltcmalloc
-
-However, if you have a reason to use the static versions of the
-library, this two-library linking won't work:
- gcc -o myapp ... /usr/lib/libprofiler.a /usr/lib/libtcmalloc.a # errors!
-
-Instead, use the special libtcmalloc_and_profiler library, which we
-make for just this purpose:
- gcc -o myapp ... /usr/lib/libtcmalloc_and_profiler.a
-
-
-CONFIGURATION OPTIONS
----------------------
-For advanced users, there are several flags you can pass to
-'./configure' that tweak tcmalloc performace. (These are in addition
-to the environment variables you can set at runtime to affect
-tcmalloc, described below.) See the INSTALL file for details.
-
-
-ENVIRONMENT VARIABLES
----------------------
-The cpu profiler, heap checker, and heap profiler will lie dormant,
-using no memory or CPU, until you turn them on. (Thus, there's no
-harm in linking -lprofiler into every application, and also -ltcmalloc
-assuming you're ok using the non-libc malloc library.)
-
-The easiest way to turn them on is by setting the appropriate
-environment variables. We have several variables that let you
-enable/disable features as well as tweak parameters.
-
-Here are some of the most important variables:
-
-HEAPPROFILE=<pre> -- turns on heap profiling and dumps data using this prefix
-HEAPCHECK=<type> -- turns on heap checking with strictness 'type'
-CPUPROFILE=<file> -- turns on cpu profiling and dumps data to this file.
-PROFILESELECTED=1 -- if set, cpu-profiler will only profile regions of code
- surrounded with ProfilerEnable()/ProfilerDisable().
-CPUPROFILE_FREQUENCY=x-- how many interrupts/second the cpu-profiler samples.
-
-TCMALLOC_DEBUG=<level> -- the higher level, the more messages malloc emits
-MALLOCSTATS=<level> -- prints memory-use stats at program-exit
-
-For a full list of variables, see the documentation pages:
- doc/cpuprofile.html
- doc/heapprofile.html
- doc/heap_checker.html
-
-
-COMPILING ON NON-LINUX SYSTEMS
-------------------------------
-
-Perftools was developed and tested on x86 Linux systems, and it works
-in its full generality only on those systems. However, we've
-successfully ported much of the tcmalloc library to FreeBSD, Solaris
-x86, and Darwin (Mac OS X) x86 and ppc; and we've ported the basic
-functionality in tcmalloc_minimal to Windows. See INSTALL for details.
-See README_windows.txt for details on the Windows port.
-
-
-PERFORMANCE
------------
-
-If you're interested in some third-party comparisons of tcmalloc to
-other malloc libraries, here are a few web pages that have been
-brought to our attention. The first discusses the effect of using
-various malloc libraries on OpenLDAP. The second compares tcmalloc to
-win32's malloc.
- http://www.highlandsun.com/hyc/malloc/
- http://gaiacrtn.free.fr/articles/win32perftools.html
-
-It's possible to build tcmalloc in a way that trades off faster
-performance (particularly for deletes) at the cost of more memory
-fragmentation (that is, more unusable memory on your system). See the
-INSTALL file for details.
-
-
-OLD SYSTEM ISSUES
------------------
-
-When compiling perftools on some old systems, like RedHat 8, you may
-get an error like this:
- ___tls_get_addr: symbol not found
-
-This means that you have a system where some parts are updated enough
-to support Thread Local Storage, but others are not. The perftools
-configure script can't always detect this kind of case, leading to
-that error. To fix it, just comment out (or delete) the line
- #define HAVE_TLS 1
-in your config.h file before building.
-
-
-64-BIT ISSUES
--------------
-
-There are two issues that can cause program hangs or crashes on x86_64
-64-bit systems, which use the libunwind library to get stack-traces.
-Neither issue should affect the core tcmalloc library; they both
-affect the perftools tools such as cpu-profiler, heap-checker, and
-heap-profiler.
-
-1) Some libc's -- at least glibc 2.4 on x86_64 -- have a bug where the
-libc function dl_iterate_phdr() acquires its locks in the wrong
-order. This bug should not affect tcmalloc, but may cause occasional
-deadlock with the cpu-profiler, heap-profiler, and heap-checker.
-Its likeliness increases the more dlopen() commands an executable has.
-Most executables don't have any, though several library routines like
-getgrgid() call dlopen() behind the scenes.
-
-2) On x86-64 64-bit systems, while tcmalloc itself works fine, the
-cpu-profiler tool is unreliable: it will sometimes work, but sometimes
-cause a segfault. I'll explain the problem first, and then some
-workarounds.
-
-Note that this only affects the cpu-profiler, which is a
-gperftools feature you must turn on manually by setting the
-CPUPROFILE environment variable. If you do not turn on cpu-profiling,
-you shouldn't see any crashes due to perftools.
-
-The gory details: The underlying problem is in the backtrace()
-function, which is a built-in function in libc.
-Backtracing is fairly straightforward in the normal case, but can run
-into problems when having to backtrace across a signal frame.
-Unfortunately, the cpu-profiler uses signals in order to register a
-profiling event, so every backtrace that the profiler does crosses a
-signal frame.
-
-In our experience, the only time there is trouble is when the signal
-fires in the middle of pthread_mutex_lock. pthread_mutex_lock is
-called quite a bit from system libraries, particularly at program
-startup and when creating a new thread.
-
-The solution: The dwarf debugging format has support for 'cfi
-annotations', which make it easy to recognize a signal frame. Some OS
-distributions, such as Fedora and gentoo 2007.0, already have added
-cfi annotations to their libc. A future version of libunwind should
-recognize these annotations; these systems should not see any
-crashses.
-
-Workarounds: If you see problems with crashes when running the
-cpu-profiler, consider inserting ProfilerStart()/ProfilerStop() into
-your code, rather than setting CPUPROFILE. This will profile only
-those sections of the codebase. Though we haven't done much testing,
-in theory this should reduce the chance of crashes by limiting the
-signal generation to only a small part of the codebase. Ideally, you
-would not use ProfilerStart()/ProfilerStop() around code that spawns
-new threads, or is otherwise likely to cause a call to
-pthread_mutex_lock!

---- COMPILING
-
-This project has begun being ported to Windows. A working solution
-file exists in this directory:
- gperftools.sln
-
-You can load this solution file into VC++ 7.1 (Visual Studio 2003) or
-later -- in the latter case, it will automatically convert the files
-to the latest format for you.
-
-When you build the solution, it will create a number of unittests,
-which you can run by hand (or, more easily, under the Visual Studio
-debugger) to make sure everything is working properly on your system.
-The binaries will end up in a directory called "debug" or "release" in
-the top-level directory (next to the .sln file). It will also create
-two binaries, nm-pdb and addr2line-pdb, which you should install in
-the same directory you install the 'pprof' perl script.
-
-I don't know very much about how to install DLLs on Windows, so you'll
-have to figure out that part for yourself. If you choose to just
-re-use the existing .sln, make sure you set the IncludeDir's
-appropriately! Look at the properties for libtcmalloc_minimal.dll.
-
-Note that these systems are set to build in Debug mode by default.
-You may want to change them to Release mode.
-
-To use tcmalloc_minimal in your own projects, you should only need to
-build the dll and install it someplace, so you can link it into
-further binaries. To use the dll, you need to add the following to
-the linker line of your executable:
- "libtcmalloc_minimal.lib" /INCLUDE:"__tcmalloc"
-
-Here is how to accomplish this in Visual Studio 2005 (VC8):
-
-1) Have your executable depend on the tcmalloc library by selecting
- "Project Dependencies..." from the "Project" menu. Your executable
- should depend on "libtcmalloc_minimal".
-
-2) Have your executable depend on a tcmalloc symbol -- this is
- necessary so the linker doesn't "optimize out" the libtcmalloc
- dependency -- by right-clicking on your executable's project (in
- the solution explorer), selecting Properties from the pull-down
- menu, then selecting "Configuration Properties" -> "Linker" ->
- "Input". Then, in the "Force Symbol References" field, enter the
- text "__tcmalloc" (without the quotes). Be sure to do this for both
- debug and release modes!
-
-You can also link tcmalloc code in statically -- see the example
-project tcmalloc_minimal_unittest-static, which does this. For this
-to work, you'll need to add "/D PERFTOOLS_DLL_DECL=" to the compile
-line of every perftools .cc file. You do not need to depend on the
-tcmalloc symbol in this case (that is, you don't need to do either
-step 1 or step 2 from above).
-
-An alternative to all the above is to statically link your application
-with libc, and then replace its malloc with tcmalloc. This allows you
-to just build and link your program normally; the tcmalloc support
-comes in a post-processing step. This is more reliable than the above
-technique (which depends on run-time patching, which is inherently
-fragile), though more work to set up. For details, see
- https://groups.google.com/group/google-perftools/browse_thread/thread/41cd3710af85e57b
-
-
---- THE HEAP-PROFILER
-
-The heap-profiler has had a preliminary port to Windows. It has not
-been well tested, and probably does not work at all when Frame Pointer
-Optimization (FPO) is enabled -- that is, in release mode. The other
-features of perftools, such as the cpu-profiler and leak-checker, have
-not yet been ported to Windows at all.
-
-
---- WIN64
-
-The function-patcher has to disassemble code, and is very
-x86-specific. However, the rest of perftools should work fine for
-both x86 and x64. In particular, if you use the 'statically link with
-libc, and replace its malloc with tcmalloc' approach, mentioned above,
-it should be possible to use tcmalloc with 64-bit windows.
-
-As of perftools 1.10, there is some support for disassembling x86_64
-instructions, for work with win64. This work is preliminary, but the
-test file preamble_patcher_test.cc is provided to play around with
-that a bit. preamble_patcher_test will not compile on win32.
-
-
---- ISSUES
-
-NOTE FOR WIN2K USERS: According to reports
-(http://code.google.com/p/gperftools/issues/detail?id=127)
-the stack-tracing necessary for the heap-profiler does not work on
-Win2K. The best workaround is, if you are building on a Win2k system
-is to add "/D NO_TCMALLOC_SAMPLES=" to your build, to turn off the
-stack-tracing. You will not be able to use the heap-profiler if you
-do this.
-
-NOTE ON _MSIZE and _RECALLOC: The tcmalloc version of _msize returns
-the size of the region tcmalloc allocated for you -- which is at least
-as many bytes you asked for, but may be more. (btw, these *are* bytes
-you own, even if you didn't ask for all of them, so it's correct code
-to access all of them if you want.) Unfortunately, the Windows CRT
-_recalloc() routine assumes that _msize returns exactly as many bytes
-as were requested. As a result, _recalloc() may not zero out new
-bytes correctly. IT'S SAFEST NOT TO USE _RECALLOC WITH TCMALLOC.
-_recalloc() is a tricky routine to use in any case (it's not safe to
-use with realloc, for instance).
-
-
-I have little experience with Windows programming, so there may be
-better ways to set this up than I've done! If you run across any
-problems, please post to the google-perftools Google Group, or report
-them on the gperftools Google Code site:

-Installing a binary distribution package
-========================================
-
-No official binary distribution packages are provided by the gflags developers.
-There may, however, be binary packages available for your OS. Please consult
-also the package repositories of your Linux distribution.
-
-For example on Debian/Ubuntu Linux, gflags can be installed using the
-following command:
-
- sudo apt-get install gflags
-
-
-Compiling the source code
-=========================
-
-The build system of gflags is since version 2.1 based on [CMake](http://cmake.org).
-The common steps to build, test, and install software are therefore:
-
-1. Extract source files.
-2. Create build directory and change to it.
-3. Run CMake to configure the build tree.
-4. Build the software using selected build tool.
-5. Test the built software.
-6. Install the built files.
-
-On Unix-like systems with GNU Make as build tool, these build steps can be
-summarized by the following sequence of commands executed in a shell,
-where ```$package``` and ```$version``` are shell variables which represent
-the name of this package and the obtained version of the software.
-
- $ tar xzf gflags-$version-source.tar.gz
- $ cd gflags-$version
- $ mkdir build && cd build
- $ ccmake ..
-
- - Press 'c' to configure the build system and 'e' to ignore warnings.
- - Set CMAKE_INSTALL_PREFIX and other CMake variables and options.
- - Continue pressing 'c' until the option 'g' is available.
- - Then press 'g' to generate the configuration files for GNU Make.
-
- $ make
- $ make test (optional)
- $ make install (optional)
-
-In the following, only gflags-specific CMake settings available to
-configure the build and installation are documented.
-
-
-CMake Option | Description
----------------------- | -------------------------------------------------------
-CMAKE_INSTALL_PREFIX | Installation directory, e.g., "/usr/local" on Unix and "C:\Program Files\gflags" on Windows.
-GFLAGS_NAMESPACE | Name of the C++ namespace to be used by the gflags library. Note that the public source header files are installed in a subdirectory named after this namespace. To maintain backwards compatibility with the Google Commandline Flags, set this variable to "google". The default is "gflags".
-GFLAGS_INCLUDE_DIR | Name of include subdirectory where headers are installed into.

-24 March 2015
--------------
-
-Released gflags 2.1.2 with fixes of ABI incompatibilities to 2.0 caused
-by namespace change. The deprecated "google" namespace is yet kept as primary
-namespace while sybmols are imported into the new "gflags" namespace by default.
-This can be configured using GFLAGS_NAMESPACE and GLAGS_INCLUDE_DIR. Problems
-with the (patched) CMake modules FindThreads.cmake and CheckTypeSize.cmake
-are resolved by re-enabling the C language again even though gflags is C++.
-
-Finalized move of gflags project from Google Code to GitHub.
-Email addresses of original issue reporters got lost in the process.
-Given the age of most issue reports, this should be neglibable.
-
-Please report any further issues using the GitHub issue tracker.
-
-
-30 March 2014
--------------
-
-I've just released gflags 2.1.1.
-
-This release fixes a few bugs in the configuration of gflags\_declare.h
-and adds a separate GFLAGS\_INCLUDE\_DIR CMake variable to the build configuration.
-Setting GFLAGS\_NAMESPACE to "google" no longer changes also the include
-path of the public header files. This allows the use of the library with
-other Google projects such as glog which still use the deprecated "google"
-namespace for the gflags library, but include it as "gflags/gflags.h".
-
-20 March 2014
--------------
-
-I've just released gflags 2.1.
-
-The major changes are the use of CMake for the build configuration instead
-of the autotools and packaging support through CPack. The default namespace
-of all C++ symbols is now "gflags" instead of "google". This can be
-configured via the GFLAGS\_NAMESPACE variable.
-
-This release compiles with all major compilers without warnings and passed
-the unit tests on Ubuntu 12.04, Windows 7 (Visual Studio 2008 and 2010,
-Cygwin, MinGW), and Mac OS X (Xcode 5.1).
-
-The SVN repository on Google Code is now frozen and replaced by a Git
-repository such that it can be used as Git submodule by projects. The main
-hosting of this project remains at Google Code. Thanks to the distributed
-character of Git, I can push (and pull) changes from both GitHub and Google Code
-in order to keep the two public repositories in sync.
-When fixing an issue for a pull request through either of these hosting
-platforms, please reference the issue number as
-[described here](https://code.google.com/p/support/wiki/IssueTracker#Integration_with_version_control).
-For the further development, I am following the
-[Git branching model](http://nvie.com/posts/a-successful-git-branching-model/)
-with feature branch names prefixed by "feature/" and bugfix branch names
-prefixed by "bugfix/", respectively.
-
-Binary and source [packages](https://github.com/schuhschuh/gflags/releases) are available on GitHub.
-
-
-14 January 2013
----------------
-
-The migration of the build system to CMake is almost complete.
-What remains to be done is rewriting the tests in Python such they can be
-executed on non-Unix platforms and splitting them up into separate CTest tests.
-Though merging these changes into the master branch yet remains to be done,
-it is recommended to already start using the
-[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration) branch.
-
-
-20 April 2013
--------------
-
-More than a year has past since I (Andreas) took over the maintenance for
-`gflags`. Only few minor changes have been made since then, much to my regret.
-To get more involved and stimulate participation in the further
-development of the library, I moved the project source code today to
-[GitHub](https://github.com/schuhschuh/gflags).
-I believe that the strengths of [Git](http://git-scm.com/) will allow for better community collaboration
-as well as ease the integration of changes made by others. I encourage everyone
-who would like to contribute to send me pull requests.
-Git's lightweight feature branches will also provide the right tool for more
-radical changes which should only be merged back into the master branch
-after these are complete and implement the desired behavior.
-
-The SVN repository remains accessible at Google Code and I will keep the
-master branch of the Git repository hosted at GitHub and the trunk of the
-Subversion repository synchronized. Initially, I was going to simply switch the
-Google Code project to Git, but in this case the SVN repository would be
-frozen and force everyone who would like the latest development changes to
-use Git as well. Therefore I decided to host the public Git repository at GitHub
-instead.
-
-Please continue to report any issues with gflags on Google Code. The GitHub project will
-only be used to host the Git repository.
-
-One major change of the project structure I have in mind for the next weeks
-is the migration from autotools to [CMake](http://www.cmake.org/).
-Check out the (unstable!)
-[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration)
-branch on GitHub for details.
-
-
-25 January 2012
----------------
-
-I've just released gflags 2.0.
-
-The `google-gflags` project has been renamed to `gflags`. I
-(csilvers) am stepping down as maintainer, to be replaced by Andreas
-Schuh. Welcome to the team, Andreas! I've seen the energy you have
-around gflags and the ideas you have for the project going forward,
-and look forward to having you on the team.
-
-I bumped the major version number up to 2 to reflect the new community
-ownership of the project. All the [changes](ChangeLog.txt)
-are related to the renaming. There are no functional changes from
-gflags 1.7. In particular, I've kept the code in the namespace
-`google`, though in a future version it should be renamed to `gflags`.
-I've also kept the `/usr/local/include/google/` subdirectory as
-synonym of `/usr/local/include/gflags/`, though the former name has
-been obsolete for some time now.
-
-
-18 January 2011
----------------
-
-The `google-gflags` Google Code page has been renamed to
-`gflags`, in preparation for the project being renamed to
-`gflags`. In the coming weeks, I'll be stepping down as
-maintainer for the gflags project, and as part of that Google is
-relinquishing ownership of the project; it will now be entirely
-community run. The name change reflects that shift.
-
-
-20 December 2011
-----------------
-
-I've just released gflags 1.7. This is a minor release; the major
-change is that `CommandLineFlagInfo` now exports the address in memory
-where the flag is located. There has also been a bugfix involving
-very long --help strings, and some other minor [changes](ChangeLog.txt).
-
-29 July 2011
-------------
-
-I've just released gflags 1.6. The major new feature in this release
-is support for setting version info, so that --version does something
-useful.
-
-One minor change has required bumping the library number:
-`ReparseCommandlineFlags` now returns `void` instead of `int` (the int
-return value was always meaningless). Though I doubt anyone ever used
-this (meaningless) return value, technically it's a change to the ABI
-that requires a version bump. A bit sad.
-
-There's also a procedural change with this release: I've changed the
-internal tools used to integrate Google-supplied patches for gflags
-into the opensource release. These new tools should result in more
-frequent updates with better change descriptions. They will also
-result in future `ChangeLog` entries being much more verbose (for better
-or for worse).
-
-See the [ChangeLog](ChangeLog.txt) for a full list of changes for this release.
-
-24 January 2011
----------------
-
-I've just released gflags 1.5. This release has only minor changes
-from 1.4, including some slightly better reporting in --help, and
-an new memory-cleanup function that can help when running gflags-using
-libraries under valgrind. The major change is to fix up the macros
-(`DEFINE_bool` and the like) to work more reliably inside namespaces.
-
-If you have not had a problem with these macros, and don't need any of
-the other changes described, there is no need to upgrade. See the
-[ChangeLog](ChangeLog.txt) for a full list of changes for this release.
-
-11 October 2010
----------------
-
-I've just released gflags 1.4. This release has only minor changes
-from 1.3, including some documentation tweaks and some work to make
-the library smaller. If 1.3 is working well for you, there's no
-particular reason to upgrade.
-
-4 January 2010
---------------
-
-I've just released gflags 1.3. gflags now compiles under MSVC, and
-all tests pass. I **really** never thought non-unix-y Windows folks
-would want gflags, but at least some of them do.
-
-The major news, though, is that I've separated out the python package
-into its own library, [python-gflags](http://code.google.com/p/python-gflags).
-If you're interested in the Python version of gflags, that's the place to
-get it now.
-
-10 September 2009
------------------
-
-I've just released gflags 1.2. The major change from gflags 1.1 is it
-now compiles under MinGW (as well as cygwin), and all tests pass. I
-never thought Windows folks would want unix-style command-line flags,
-since they're so different from the Windows style, but I guess I was
-wrong!
-
-The other changes are minor, such as support for --htmlxml in the
-python version of gflags.
-
-15 April 2009
--------------
-
-I've just released gflags 1.1. It has only minor changes fdrom gflags
-1.0 (see the [ChangeLog](ChangeLog.txt) for details).
-The major change is that I moved to a new system for creating .deb and .rpm files.
-This allows me to create x86\_64 deb and rpm files.
-
-In the process of moving to this new system, I noticed an
-inconsistency: the tar.gz and .rpm files created libraries named
-libgflags.so, but the deb file created libgoogle-gflags.so. I have
-fixed the deb file to create libraries like the others. I'm no expert
-in debian packaging, but I believe this has caused the package name to
-change as well. Please let me know (at
-[[mailto:google-gflags@googlegroups.com](mailto:google-gflags@googlegroups.com)
-google-gflags@googlegroups.com]) if this causes problems for you --
-especially if you know of a fix! I would be happy to change the deb
-packages to add symlinks from the old library name to the new
-(libgoogle-gflags.so -> libgflags.so), but that is beyond my knowledge
-of how to make .debs.
-
-If you've tried to install a .rpm or .deb and it doesn't work for you,
-let me know. I'm excited to finally have 64-bit package files, but
-there may still be some wrinkles in the new system to iron out.
-
-1 October 2008
---------------
-
-gflags 1.0rc2 was out for a few weeks without any issues, so gflags
-1.0 is now released. This is much like gflags 0.9. The major change
-is that the .h files have been moved from `/usr/include/google` to
-`/usr/include/gflags`. While I have backwards-compatibility
-forwarding headeds in place, please rewrite existing code to say
-```
- #include <gflags/gflags.h>
-```
-instead of
-```
- #include <google/gflags.h>
-```
-
-I've kept the default namespace to google. You can still change with
-with the appropriate flag to the configure script (`./configure
---help` to see the flags). If you have feedback as to whether the
-default namespace should change to gflags, which would be a
-non-backwards-compatible change, send mail to
-`google-gflags@googlegroups.com`!
-
-Version 1.0 also has some neat new features, like support for bash
-commandline-completion of help flags. See the [ChangeLog](ChangeLog.txt)
-for more details.
-
-If I don't hear any bad news for a few weeks, I'll release 1.0-final.

-<h2> <A NAME=intro>Introduction, and Comparison to Other Commandline
- Flags Libraries</A> </h2>
-
-<p><b>Commandline flags</b> are flags that users specify on the
-command line when they run an executable. In the command</p>
-<pre>
- fgrep -l -f /var/tmp/foo johannes brahms
-</pre>
-<p><code>-l</code> and <code>-f /var/tmp/foo</code> are the two
-commandline flags. (<code>johannes</code> and <code>brahms</code>,
-which don't start with a dash, are <b>commandline arguments</b>.)</p>
-
-<p>Typically, an application lists what flags the user is allowed to
-pass in, and what arguments they take -- in this example,
-<code>-l</code> takes no argument, and <code>-f</code> takes a
-string (in particular, a filename) as an argument. Users can use a
-library to help parse the commandline and store the flags in some data
-structure.</p>
-
-<p>Gflags, the commandline flags library used within Google,
-differs from other libraries,
-such as <code>getopt()</code>, in that flag definitions can be
-scattered around the source code, and not just listed in one place
-such as <code>main()</code>. In practice, this means that a single
-source-code file will define and use flags that are meaningful to that
-file. Any application that links in that file will get the flags, and
-the gflags library will automatically handle that
-flag appropriately.</p>
-
-<p>There's significant gain in flexibility, and ease of code reuse,
-due to this technique. However, there is a danger that two files will
-define the same flag, and then give an error when they're linked
-together.</p>
-
-<p>The rest of this document describes how to use the commandlineflag
-library. It's a C++ library, so examples are in C++. However, there
-is a Python port with the same functionality, and this discussion
-translates directly to Python.</p>
-
-<h2> <A name=cmake>Finding and Linking to gflags </A> using CMake</h2>
-
-<p> Using gflags within a project which uses <A href="http://www.cmake.org">CMake</A> for its build system is easy. Therefore, simply add the following CMake code to your <code>CMakeLists.txt</code> file.
-
-<pre>
- find_package (gflags REQUIRED)
- include_directories (${gflags_INCLUDE_DIR})
-
- add_executable (foo main.cc)
- target_link_libraries (foo gflags)
-</pre>
-
-<h2> <A name=define>DEFINE: Defining Flags In Program</A> </h2>
-
-<p> Defining a flag is easy: just use the appropriate macro for the
-type you want the flag to be, as defined at the bottom of
-<code>gflags/gflags.h</code>. Here's an example file,
-<code>foo.cc</code>:</p>
-
-<pre>
- #include <gflags/gflags.h>
-
- DEFINE_bool(big_menu, true, "Include 'advanced' options in the menu listing");
- DEFINE_string(languages, "english,french,german",
- "comma-separated list of languages to offer in the 'lang' menu");
-</pre>
-
-<p><code>DEFINE_bool</code> defines a boolean flag. Here are the
-types supported:</p>
-<ul>
- <li> <code>DEFINE_bool</code>: boolean
- <li> <code>DEFINE_int32</code>: 32-bit integer
- <li> <code>DEFINE_int64</code>: 64-bit integer
- <li> <code>DEFINE_uint64</code>: unsigned 64-bit integer
- <li> <code>DEFINE_double</code>: double
- <li> <code>DEFINE_string</code>: C++ string
-</ul>
-
-<p>Note that there are no 'complex' types like lists: the "languages"
-flag in our example is a list of strings, but is defined of type
-"string", not "list_of_string" or similar. This is by design. We'd
-rather use only simple types for the flags, and allow for complex,
-arbitrary parsing routines to parse them, than to try to put the logic
-inside the flags library proper.</p>
-
-<p>All DEFINE macros take the same three arguments: the name of the
-flag, its default value, and a 'help' string that describes its use.
-The 'help' string is displayed when the user runs the application with
-the <A HREF="#special"><code>--help</code> flag</A>.</p>
-
-<p>You can define a flag in any source-code file in your executable.
-Only define a flag once! If you want to access a flag in more than
-one source file, DEFINE it in one file, and <A
-HREF="#declare">DECLARE</A> it in the others. Even better, DEFINE it
-in <code>foo.cc</code> and DECLARE it in <code>foo.h</code>; then
-everyone who <code>#includes foo.h</code> can use the flag.</p>
-
-<p>
-Defining flags in libraries rather than in main() is powerful, but
-does have some costs. One is that a library might not have a good
-default value for its flags, for example if the flag holds a
-filename that might not exist in some environments. To mitigate such problems,
-you can use <a href="#validate">flag validators</a> to ensure prompt
-notification (in the form of a crash) of an invalid flag value.
-</p>
-
-<p>Note that while most functions in this library are defined in the
-<code>google</code> namespace, <code>DEFINE_foo</code> (and
-<code>DECLARE_foo</code>, <A HREF="#declare">below</A>), should always
-be in the global namespace.</p>
-
-
-<h2> <A name=using>Accessing the Flag</A> </h2>
-
-<p>All defined flags are available to the program as just a normal
-variable, with the prefix <code>FLAGS_</code> prepended. In the above
-example, the macros define two variables, <code>FLAGS_big_menu</code>
-(a bool), and <code>FLAGS_languages</code> (a C++ string).</p>
-
-<p>You can read and write to the flag just like any other
-variable:</p>
-<pre>
- if (FLAGS_consider_made_up_languages)
- FLAGS_languages += ",klingon"; // implied by --consider_made_up_languages
- if (FLAGS_languages.find("finnish") != string::npos)
- HandleFinnish();
-</pre>
-
-<p>You can also get and set flag values via special functions in
-<code>gflags.h</code>. That's a rarer use case, though.</p>
-
-
-<h2> <A name=declare>DECLARE: Using the Flag in a Different File</A> </h2>
-
-<p>Accessing a flag in the manner of the previous section only works
-if the flag was <code>DEFINE</code>-ed at the top of the file. If it
-wasn't, you'll get an 'unknown variable' error.</p>
-
-<p>The <code>DECLARE_type</code> macro is available when you want to
-use a flag that's defined in another file. For instance, if I were
-writing <code>bar.cc</code> but wanted to access the big_menu, flag, I
-would put this near the top of <code>bar.cc</code>:</p>
-<pre>
- DECLARE_bool(big_menu);
-</pre>
-
-<p>This is functionally equivalent to saying <code>extern
-FLAGS_big_menu</code>.</p>
-
-<p>Note that such an extern declaration introduces a dependency
-between your file and the file that defines the <code>big_menu</code>
-flag: <code>foo.cc</code>, in this case. Such implicit dependencies
-can be difficult to manage in large projects. For that reason we
-recommend the following guideline:</p>
-
-<blockquote>
-If you DEFINE a flag in <code>foo.cc</code>, either don't DECLARE it
-at all, only DECLARE it in tightly related tests, or only DECLARE
-it in <code>foo.h</code>.
-</blockquote>
-
-<p>You should go the do-not-DECLARE route when the flag is only needed
-by <code>foo.cc</code>, and not in any other file. If you want to
-modify the value of the flag in the related test file to see if it is
-functioning as expected, DECLARE it in the <code>foo_test.cc</code>
-file.
-
-<p>If the flag does span multiple files, DECLARE it in the associated
-<code>.h</code> file, and make others <code>#include</code> that
-<code>.h</code> file if they want to access the flag. The
-<code>#include</code> will make explicit the dependency between the
-two files. This causes the flag to be a global variable.</p>
-
-
-<h2> <A name=validate>RegisterFlagValidator: Sanity-checking Flag Values</A> </h2>
-
-<p>After DEFINE-ing a flag, you may optionally register a validator
-function with the flag. If you do this, after the flag is parsed from
-the commandline, and whenever its value is changed via a call to
-<code>SetCommandLineOption()</code>, the validator function is called
-with the new value as an argument. The validator function should
-return 'true' if the flag value is valid, and false otherwise.
-If the function returns false for the new setting of the
-flag, the flag will retain its current value. If it returns false for the
-default value, ParseCommandLineFlags will die.
-
-<p>Here is an example use of this functionality:</p>
-<pre>
-static bool ValidatePort(const char* flagname, int32 value) {
- if (value > 0 && value < 32768) // value is ok
- return true;
- printf("Invalid value for --%s: %d\n", flagname, (int)value);
- return false;
-}
-DEFINE_int32(port, 0, "What port to listen on");
-static const bool port_dummy = RegisterFlagValidator(&FLAGS_port, &ValidatePort);
-</pre>
-
-<p>By doing the registration at global initialization time (right
-after the DEFINE), we ensure that the registration happens before
-the commandline is parsed at the beginning of <code>main()</code>.</p>
-
-<p><code>RegisterFlagValidator()</code> returns true if the
-registration is successful. It return false if the registration fails
-because a) the first argument does not refer to a commandline flag, or
-b) a different validator has already been registered for this flag.</p>
-
-
-<h2> <A name=together>Putting It Together: How to Set Up Flags</A> </h2>
-
-<p>The final piece is the one that tells the executable to process the
-commandline flags, and set the <code>FLAGS_*</code> variables to the
-appropriate, non-default value based on what is seen on the
-commandline. This is equivalent to the <code>getopt()</code> call in
-the getopt library, but has much less overhead to use. In fact, it's
-just a single function call:</p>
-
-<pre>
- gflags::ParseCommandLineFlags(&argc, &argv, true);
-</pre>
-
-<p>Usually, this code is at the beginning of <code>main()</code>.
-<code>argc</code> and <code>argv</code> are exactly as passed in to
-<code>main()</code>. This routine might modify them, which is why
-pointers to them are passed in.</p>
-
-<p>The last argument is called "remove_flags". If true, then
-<code>ParseCommandLineFlags</code> removes the flags and their
-arguments from <code>argv</code>, and modifies <code>argc</code>
-appropriately. In this case, after the function call,
-<code>argv</code> will hold only commandline arguments, and not
-commandline flags.</p>
-
-<p>If, on the other hand, <code>remove_flags</code> is false, then
-<code>ParseCommandLineFlags</code> will leave argc unchanged, but will
-rearrange the arguments in argv so that the flags are all at the
-beginning. For example, if the input is <code>"/bin/foo" "arg1" "-q"
-"arg2"</code> (which is legal but weird), the function will rearrange
-<code>argv</code> so it reads <code>"/bin/foo", "-q", "arg1",
-"arg2"</code>. In this case, <code>ParseCommandLineFlags</code>
-returns the index into argv that holds the first commandline argument:
-that is, the index past the last flag. (In this example, it would
-return 2, since <code>argv[2]</code> points to <code>arg1</code>.)</p>
-
-<p>In either case, the <code>FLAGS_*</code> variables are modified
-based on what was <A HREF="#commandline">passed in on the
-commandline</A>.</p>
-
-
-<h2> <A name=commandline>Setting Flags on the Command Line</A> </h2>
-
-<p>The reason you make something a flag instead of a compile-time
-constant, is so users can specify a non-default value on the
-commandline. Here's how they might do it for an application that
-links in <code>foo.cc</code>:</p>
-<pre>
- app_containing_foo --nobig_menu -languages="chinese,japanese,korean" ...
-</pre>
-
-<p>This sets <code>FLAGS_big_menu = false;</code> and
-<code>FLAGS_languages = "chinese,japanese,korean"</code>, when
-<code>ParseCommandLineFlags</code> is run.</p>
-
-<p>Note the atypical syntax for setting a boolean flag to false:
-putting "no" in front of its name. There's a fair bit of flexibility
-to how flags may be specified. Here's an example of all the ways to
-specify the "languages" flag:</p>
-<ul>
- <li> <code>app_containing_foo --languages="chinese,japanese,korean"</code>
- <li> <code>app_containing_foo -languages="chinese,japanese,korean"</code>
- <li> <code>app_containing_foo --languages "chinese,japanese,korean"</code>
- <li> <code>app_containing_foo -languages "chinese,japanese,korean"</code>
-</ul>
-
-<p>For boolean flags, the possibilities are slightly different:</p>
-<ul>
- <li> <code>app_containing_foo --big_menu</code>
- <li> <code>app_containing_foo --nobig_menu</code>
- <li> <code>app_containing_foo --big_menu=true</code>
- <li> <code>app_containing_foo --big_menu=false</code>
-</ul>
-<p>(as well as the single-dash variant on all of these).</p>
-
-<p>Despite this flexibility, we recommend using only a single form:
-<code>--variable=value</code> for non-boolean flags, and
-<code>--variable/--novariable</code> for boolean flags. This
-consistency will make your code more readable, and is also the format
-required for certain special-use cases like <A
-HREF="#flagfiles">flagfiles</A>.</p>
-
-<p>It is a fatal error to specify a flag on the commandline that has
-not been DEFINED somewhere in the executable. If you need that
-functionality for some reason -- say you want to use the same set of
-flags for several executables, but not all of them DEFINE every flag
-in your list -- you can specify <A
-HREF="#special"><code>--undefok</code></A> to suppress the error.</p>
-
-<p>As in getopt(), <code>--</code> by itself will terminate flags
-processing. So in <code>foo -f1 1 -- -f2 2</code>, <code>f1</code> is
-considered a flag, but <code>-f2</code> is not.</p>
-
-<p>If a flag is specified more than once, only the last specification
-is used; the others are ignored.</p>
-
-<p>Note that flags do not have single-letter synonyms, like they do in
-the getopt library, nor do we allow "combining" flags behind a
-single dash, as in <code>ls -la</code>.</p>
-

-<h2> <A name=default>Changing the Default Flag Value</A> </h2>
-
-<p>Sometimes a flag is defined in a library, and you want to change
-its default value in one application but not others. It's simple to
-do this: just assign a new value to the flag in <code>main()</code>,
-before calling <code>ParseCommandLineFlags()</code>:</p>
-<pre>
- DECLARE_bool(lib_verbose); // mylib has a lib_verbose flag, default is false
- int main(int argc, char** argv) {
- FLAGS_lib_verbose = true; // in my app, I want a verbose lib by default
- ParseCommandLineFlags(...);
- }
-</pre>
-
-<p>For this application, users can still set the flag value on the
-commandline, but if they do not, the flag's value will default to
-true.</p>
-
-
-<h2> <A name="special">Special Flags</a> </h2>
-
-<p>There are a few flags defined by the commandlineflags module
-itself, and are available to all applications that use
-commandlineflags. These fall into
-three categories. First are the 'reporting' flags that, when found, cause
-the application to print some information about itself and exit.</p>
-
-<table><tr valign=top>
- <td><code>--help</code></td>
- <td>shows all flags from all files, sorted by file and then by name;
- shows the flagname, its default value, and its help string</td>
-</tr><tr valign=top>
- <td><code>--helpfull</code></td>
- <td>same as -help, but unambiguously asks for all flags
- (in case -help changes in the future)</td>
-</tr><tr valign=top>
- <td><code>--helpshort</code></td>
- <td>shows only flags for the file with the same name as the executable
- (usually the one containing <code>main()</code>)</td>
-</tr><tr valign=top>
- <td><code>--helpxml</code></td>
- <td>like --help, but output is in xml for easier parsing</td>
-</tr><tr valign=top>
- <td><code>--helpon=FILE </code></td>
- <td>shows only flags defined in FILE.*</td>
-</tr><tr valign=top>
- <td><code>--helpmatch=S</code></td>
- <td>shows only flags defined in *S*.*</td>
-</tr><tr valign=top>
- <td><code>--helppackage</code></td>
- <td>shows flags defined in files in same directory as <code>main()</code></td>
-</tr><tr valign=top>
- <td><code>--version</code></td>
- <td>prints version info for the executable</td>
-</tr></table>
-
-<p>Second are the flags that affect how other flags are parsed.</p>
-
-<table><tr valign=top>
- <td><code>--undefok=flagname,flagname,...</code></td>
- <td>for those names listed as the argument to <code>--undefok</code>,
- suppress the normal error-exit that occurs when
- <code>--name</code> is seen on the commandline, but
- <code>name</code> has not been DEFINED anywhere in the
- application
-</table>
-
-<p>Third are the 'recursive' flags, that cause other flag values to be
-set: <code>--fromenv</code>, <code>--tryfromenv</code>,
-<code>--flagfile</code>. These are described below in more
-detail.</p>
-
-<h3> <code>--fromenv</code> </h3>
-
-<p><code>--fromenv=foo,bar</code> says to read the values for the
-<code>foo</code> and <code>bar</code> flags from the environment.
-In concert with this flag, you must actually set the values in the
-environment, via a line like one of the two below:</p>
-<pre>
- export FLAGS_foo=xxx; export FLAGS_bar=yyy # sh
- setenv FLAGS_foo xxx; setenv FLAGS_bar yyy # tcsh
-</pre>
-<p>This is equivalent to specifying <code>--foo=xxx</code>,
-<code>--bar=yyy</code> on the commandline.</p>
-
-<p>Note it is a fatal error to say <code>--fromenv=foo</code> if
-<code>foo</code> is not DEFINED somewhere in the application. (Though
-you can suppress this error via <code>--undefok=foo</code>, just like
-for any other flag.)</p>
-
-<p>It is also a fatal error to say <code>--fromenv=foo</code> if
-<code>FLAGS_foo</code> is not actually defined in the environment.</p>
-
-<h3> <code>--tryfromenv</code> </h3>
-
-<p><code>--tryfromenv</code> is exactly like <code>--fromenv</code>,
-except it is <b>not</b> a fatal error to say
-<code>--tryfromenv=foo</code> if <code>FLAGS_foo</code> is not
-actually defined in the environment. Instead, in such cases,
-<code>FLAGS_foo</code> just keeps its default value as specified in
-the application.</p>
-
-<p>Note it is still an error to say <code>--tryfromenv=foo</code> if
-<code>foo</code> is not DEFINED somewhere in the application.</p>
-
-<h3> <code>--flagfile</code> </h3>
-
-<p><code>--flagfile=f</code> tells the commandlineflags module to read
-the file <code>f</code>, and to run all the flag-assignments found in
-that file as if these flags had been specified on the commandline.</p>
-
-<p>In its simplest form, <code>f</code> should just be a list of flag
-assignments, one per line. Unlike on the commandline, the equals sign
-separating a flagname from its argument is <i>required</i> for
-flagfiles. An example flagfile, <code>/tmp/myflags</code>:</p>
-<pre>
---nobig_menus
---languages=english,french
-</pre>
-
-<p>With this flagfile, the following two lines are equivalent:<p>
-<pre>
- ./myapp --foo --nobig_menus --languages=english,french --bar
- ./myapp --foo --flagfile=/tmp/myflags --bar
-</pre>
-
-<p>Note that many errors are silently suppressed in flagfiles. In
-particular, unrecognized flagnames are silently ignored, as are flags
-that are missing a required value (e.g., a flagfile that just says
-<code>--languages</code>).</p>
-
-<p>The general format of a flagfile is a bit more complicated than the
-simple, common case above. It is: a sequence of filenames, one per
-line, followed by a sequence of flags, one per line, repeated as many
-times as desired. Filenames in a flagfile can use wildcards
-(<code>*</code> and <code>?</code>), and the sequence of flags located
-after a sequence of filenames is processed only if the current
-executable's name matches one of the filenames. It is possible to
-start the flagfile with a sequence of flags instead of a sequence of
-filenames; if such a sequence of flags is present, these flags are
-applied to the current executable no matter what it is.</p>
-
-<p>Lines that start with a <code>#</code> are ignored as comments.
-Leading whitespace is also ignored in flagfiles, as are blank
-lines.</p>
-
-<p>It is possible for a flagfile to use the <code>--flagfile</code>
-flag to include another flagfile.</p>
-
-<p>Flags are always processed in the expected order. That is,
-processing begins by examining the flags specified directly on the
-command line. If a flagfile is specified, its contents are processed,
-and then processing continues with remaining flags from the command
-line.</p>
-
-
-<h2> <A name="api">The API</a> </h2>
-
-<p>In addition to accessing <code>FLAGS_foo</code> directly, it is
-possible to access the flags programmatically, through an API. It is
-also possible to access information about a flag, such as its default
-value and help-string. A <code>FlagSaver</code> makes it easy to
-modify flags and then automatically undo the modifications later.
-Finally, there are somewhat unrelated, but useful, routines to easily
-access parts of <code>argv</code> outside main, including the program
-name (<code>argv[0]</code>).</p>
-
-<p>For more information about these routines, and other useful helper
-methods such as <code>gflags::SetUsageMessage()</code> and
-<code>gflags::SetVersionString</code>, see <code>gflags.h</code>.</p>
-
-
-<h2> <A name="misc">Miscellaneous Notes</code> </h2>
-
-<p>If your application has code like this:</p>
-<pre>
- #define STRIP_FLAG_HELP 1 // this must go before the #include!
- #include <gflags/gflags.h>
-</pre>
-<p>we will remove the help messages from the compiled source. This can
-reduce the size of the resulting binary somewhat, and may also be
-useful for security reasons.</p>

-// This is an internal header file used by profiler.cc. It defines

-// handler to figure out the instruction that was being executed when
-// the signal-handler was triggered.
-//
-// To get this, we use the ucontext_t argument to the signal-handler
-// callback, which holds the full context of what was going on when
-// the signal triggered. How to get from a ucontext_t to a Program
-// Counter is OS-dependent.

-// is not properly set up (either before it's done being set up, or
-// after it's been torn down but before Bar() returns). In those

-//
-// Background and key design points of MemoryRegionMap.
-//
-// MemoryRegionMap is a low-level module with quite atypical requirements that
-// result in some degree of non-triviality of the implementation and design.
-//
-// MemoryRegionMap collects info about *all* memory regions created with
-// mmap, munmap, mremap, sbrk.
-// They key word above is 'all': all that are happening in a process
-// during its lifetime frequently starting even before global object
-// constructor execution.
-//
-// This is needed by the primary client of MemoryRegionMap:
-// HeapLeakChecker uses the regions and the associated stack traces
-// to figure out what part of the memory is the heap:
-// if MemoryRegionMap were to miss some (early) regions, leak checking would
-// stop working correctly.
-//
-// To accomplish the goal of functioning before/during global object
-// constructor execution MemoryRegionMap is done as a singleton service
-// that relies on own on-demand initialized static constructor-less data,
-// and only relies on other low-level modules that can also function properly
-// even before global object constructors run.
-//
-// Accomplishing the goal of collecting data about all mmap, munmap, mremap,
-// sbrk occurrences is a more involved: conceptually to do this one needs to
-// record some bits of data in particular about any mmap or sbrk call,
-// but to do that one needs to allocate memory for that data at some point,
-// but all memory allocations in the end themselves come from an mmap
-// or sbrk call (that's how the address space of the process grows).
-//
-// Also note that we need to do all the above recording from
-// within an mmap/sbrk hook which is sometimes/frequently is made by a memory
-// allocator, including the allocator MemoryRegionMap itself must rely on.
-// In the case of heap-checker usage this includes even the very first
-// mmap/sbrk call happening in the program: heap-checker gets activated due to
-// a link-time installed mmap/sbrk hook and it initializes MemoryRegionMap
-// and asks it to record info about this very first call right from that
-// very first hook invocation.
-//
-// MemoryRegionMap is doing its memory allocations via LowLevelAlloc:
-// unlike more complex standard memory allocator, LowLevelAlloc cooperates with
-// MemoryRegionMap by not holding any of its own locks while it calls mmap
-// to get memory, thus we are able to call LowLevelAlloc from
-// our mmap/sbrk hooks without causing a deadlock in it.
-// For the same reason of deadlock prevention the locking in MemoryRegionMap
-// itself is write-recursive which is an exception to Google's mutex usage.
-//
-// We still need to break the infinite cycle of mmap calling our hook,
-// which asks LowLevelAlloc for memory to record this mmap,
-// which (sometimes) causes mmap, which calls our hook, and so on.
-// We do this as follows: on a recursive call of MemoryRegionMap's
-// mmap/sbrk/mremap hook we record the data about the allocation in a
-// static fixed-sized stack (saved_regions and saved_buckets), when the
-// recursion unwinds but before returning from the outer hook call we unwind
-// this stack and move the data from saved_regions and saved_buckets to its
-// permanent place in the RegionSet and "bucket_table" respectively,
-// which can cause more allocations and mmap-s and recursion and unwinding,
-// but the whole process ends eventually due to the fact that for the small
-// allocations we are doing LowLevelAlloc reuses one mmap call and parcels out
-// the memory it created to satisfy several of our allocation requests.

-// Revamped and reorganized by Craig Silverstein
-//
-// This file contains the implementation of all our command line flags
-// stuff. Here's how everything fits together
-//
-// * FlagRegistry owns CommandLineFlags owns FlagValue.
-// * FlagSaver holds a FlagRegistry (saves it at construct time,
-// restores it at destroy time).
-// * CommandLineFlagParser lives outside that hierarchy, but works on
-// CommandLineFlags (modifying the FlagValues).
-// * Free functions like SetCommandLineOption() work via one of the
-// above (such as CommandLineFlagParser).
-//
-// In more detail:
-//
-// -- The main classes that hold flag data:
-//
-// FlagValue holds the current value of a flag. It's
-// pseudo-templatized: every operation on a FlagValue is typed. It
-// also deals with storage-lifetime issues (so flag values don't go
-// away in a destructor), which is why we need a whole class to hold a
-// variable's value.
-//
-// CommandLineFlag is all the information about a single command-line
-// flag. It has a FlagValue for the flag's current value, but also
-// the flag's name, type, etc.
-//
-// FlagRegistry is a collection of CommandLineFlags. There's the
-// global registry, which is where flags defined via DEFINE_foo()
-// live. But it's possible to define your own flag, manually, in a
-// different registry you create. (In practice, multiple registries
-// are used only by FlagSaver).
-//
-// A given FlagValue is owned by exactly one CommandLineFlag. A given
-// CommandLineFlag is owned by exactly one FlagRegistry. FlagRegistry
-// has a lock; any operation that writes to a FlagValue or
-// CommandLineFlag owned by that registry must acquire the
-// FlagRegistry lock before doing so.
-//
-// --- Some other classes and free functions:
-//
-// CommandLineFlagInfo is a client-exposed version of CommandLineFlag.
-// Once it's instantiated, it has no dependencies or relationships
-// with any other part of this file.
-//
-// FlagRegisterer is the helper class used by the DEFINE_* macros to
-// allow work to be done at global initialization time.
-//
-// CommandLineFlagParser is the class that reads from the commandline
-// and instantiates flag values based on that. It needs to poke into
-// the innards of the FlagValue->CommandLineFlag->FlagRegistry class
-// hierarchy to do that. It's careful to acquire the FlagRegistry
-// lock before doing any writing or other non-const actions.
-//
-// GetCommandLineOption is just a hook into registry routines to
-// retrieve a flag based on its name. SetCommandLineOption, on the
-// other hand, hooks into CommandLineFlagParser. Other API functions
-// are, similarly, mostly hooks into the functionality described above.

-# How to contribute #
-
-We'd love to accept your patches and contributions to this project. There are
-a just a few small guidelines you need to follow.
-
-
-## Contributor License Agreement ##
-
-Contributions to any Google project must be accompanied by a Contributor
-License Agreement. This is not a copyright **assignment**, it simply gives
-Google permission to use and redistribute your contributions as part of the
-project.
-
- * If you are an individual writing original source code and you're sure you
- own the intellectual property, then you'll need to sign an [individual
- CLA][].
-
- * If you work for a company that wants to allow you to contribute your work,
- then you'll need to sign a [corporate CLA][].
-
-You generally only need to submit a CLA once, so if you've already submitted
-one (even if it was for a different project), you probably don't need to do it
-again.
-
-[individual CLA]: https://developers.google.com/open-source/cla/individual
-[corporate CLA]: https://developers.google.com/open-source/cla/corporate
-
-Once your CLA is submitted (or if you already submitted one for
-another Google project), make a commit adding yourself to the
-[AUTHORS][] and [CONTRIBUTORS][] files. This commit can be part
-of your first [pull request][].
-
-[AUTHORS]: AUTHORS
-[CONTRIBUTORS]: CONTRIBUTORS
-
-
-## Submitting a patch ##
-
- 1. It's generally best to start by opening a new issue describing the bug or
- feature you're intending to fix. Even if you think it's relatively minor,
- it's helpful to know what people are working on. Mention in the initial
- issue that you are planning to work on that bug or feature so that it can
- be assigned to you.
-
- 1. Follow the normal process of [forking][] the project, and setup a new
- branch to work in. It's important that each group of changes be done in
- separate branches in order to ensure that a pull request only includes the
- commits related to that bug or feature.
-
- 1. Do your best to have [well-formed commit messages][] for each change.
- This provides consistency throughout the project, and ensures that commit
- messages are able to be formatted properly by various git tools.
-
- 1. Finally, push the commits to your fork and submit a [pull request][].

-benchmark
-=========
-[](https://travis-ci.org/google/benchmark)
-
-A library to support the benchmarking of functions, similar to unit-tests.
-
-Discussion group: https://groups.google.com/d/forum/benchmark-discuss
-
-Example usage
--------------
-Define a function that executes the code to be measured a
-specified number of times:
-
-```c++
-static void BM_StringCreation(benchmark::State& state) {
- while (state.KeepRunning())
- std::string empty_string;
-}
-// Register the function as a benchmark
-BENCHMARK(BM_StringCreation);
-
-// Define another benchmark
-static void BM_StringCopy(benchmark::State& state) {
- std::string x = "hello";
- while (state.KeepRunning())
- std::string copy(x);
-}
-BENCHMARK(BM_StringCopy);
-
-// Augment the main() program to invoke benchmarks if specified
-// via the --benchmarks command line flag. E.g.,
-// my_unittest --benchmark_filter=all
-// my_unittest --benchmark_filter=BM_StringCreation
-// my_unittest --benchmark_filter=String
-// my_unittest --benchmark_filter='Copy|Creation'
-int main(int argc, const char* argv[]) {
- benchmark::Initialize(&argc, argv);
- benchmark::RunSpecifiedBenchmarks();
- return 0;
-}
-```
-
-Sometimes a family of microbenchmarks can be implemented with
-just one routine that takes an extra argument to specify which
-one of the family of benchmarks to run. For example, the following
-code defines a family of microbenchmarks for measuring the speed
-of `memcpy()` calls of different lengths:
-
-```c++
-static void BM_memcpy(benchmark::State& state) {
- char* src = new char[state.range_x()]; char* dst = new char[state.range_x()];
- memset(src, 'x', state.range_x());
- while (state.KeepRunning())
- memcpy(dst, src, state.range_x());
- state.SetBytesProcessed(int64_t(state.iterations) * int64_t(state.range_x()));
- delete[] src;
- delete[] dst;
-}
-BENCHMARK(BM_memcpy)->Arg(8)->Arg(64)->Arg(512)->Arg(1<<10)->Arg(8<<10);
-```
-
-The preceding code is quite repetitive, and can be replaced with the
-following short-hand. The following invocation will pick a few
-appropriate arguments in the specified range and will generate a
-microbenchmark for each such argument.
-
-```c++
-BENCHMARK(BM_memcpy)->Range(8, 8<<10);
-```
-
-You might have a microbenchmark that depends on two inputs. For
-example, the following code defines a family of microbenchmarks for
-measuring the speed of set insertion.
-
-```c++
-static void BM_SetInsert(benchmark::State& state) {
- while (state.KeepRunning()) {
- state.PauseTiming();
- std::set<int> data = ConstructRandomSet(state.range_x());
- state.ResumeTiming();
- for (int j = 0; j < state.rangeY; ++j)
- data.insert(RandomNumber());
- }
-}
-BENCHMARK(BM_SetInsert)
- ->ArgPair(1<<10, 1)
- ->ArgPair(1<<10, 8)
- ->ArgPair(1<<10, 64)
- ->ArgPair(1<<10, 512)
- ->ArgPair(8<<10, 1)
- ->ArgPair(8<<10, 8)
- ->ArgPair(8<<10, 64)
- ->ArgPair(8<<10, 512);
-```
-
-The preceding code is quite repetitive, and can be replaced with
-the following short-hand. The following macro will pick a few
-appropriate arguments in the product of the two specified ranges
-and will generate a microbenchmark for each such pair.
-
-```c++
-BENCHMARK(BM_SetInsert)->RangePair(1<<10, 8<<10, 1, 512);
-```
-
-For more complex patterns of inputs, passing a custom function
-to Apply allows programmatic specification of an
-arbitrary set of arguments to run the microbenchmark on.
-The following example enumerates a dense range on one parameter,
-and a sparse range on the second.
-
-```c++
-static benchmark::internal::Benchmark* CustomArguments(
- benchmark::internal::Benchmark* b) {
- for (int i = 0; i <= 10; ++i)
- for (int j = 32; j <= 1024*1024; j *= 8)
- b = b->ArgPair(i, j);
- return b;
-}
-BENCHMARK(BM_SetInsert)->Apply(CustomArguments);
-```
-
-Templated microbenchmarks work the same way:
-Produce then consume 'size' messages 'iters' times
-Measures throughput in the absence of multiprogramming.
-
-```c++
-template <class Q> int BM_Sequential(benchmark::State& state) {
- Q q;
- typename Q::value_type v;
- while (state.KeepRunning()) {
- for (int i = state.range_x(); i--; )
- q.push(v);
- for (int e = state.range_x(); e--; )
- q.Wait(&v);
- }
- // actually messages, not bytes:
- state.SetBytesProcessed(
- static_cast<int64_t>(state.iterations())*state.range_x());
-}
-BENCHMARK_TEMPLATE(BM_Sequential, WaitQueue<int>)->Range(1<<0, 1<<10);
-```
-
-In a multithreaded test, it is guaranteed that none of the threads will start
-until all have called KeepRunning, and all will have finished before KeepRunning
-returns false. As such, any global setup or teardown you want to do can be
-wrapped in a check against the thread index:
-
-```c++
-static void BM_MultiThreaded(benchmark::State& state) {
- if (state.thread_index == 0) {
- // Setup code here.
- }
- while (state.KeepRunning()) {
- // Run the test as normal.
- }
- if (state.thread_index == 0) {
- // Teardown code here.
- }
-}
-BENCHMARK(BM_MultiThreaded)->Threads(2);
-```
-
-Linking against the library
----------------------------
-When using gcc, it is necessary to link against pthread to avoid runtime exceptions. This is due to how gcc implements std::thread. See [issue #67](https://github.com/google/benchmark/issues/67) for more details.

-// HandleCommandLineHelpFlags() will check what 'reporting' flags have
-// been defined, if any -- the "help" part of the function name is a
-// bit misleading -- and do the relevant reporting. It should be
-// called after all flag-values have been assigned, that is, after
-// parsing the command-line.

-// A simple mutex wrapper, supporting locks and read-write locks.
-// You should assume the locks are *not* re-entrant.
-//
-// This class is meant to be internal-only and should be wrapped by an
-// internal namespace. Before you use this module, please give the
-// name of your internal namespace for this module. Or, if you want
-// to expose it, you'll want to move it to the Google namespace. We
-// cannot put this class in global namespace because there can be some
-// problems when we have multiple versions of Mutex in each shared object.
-//
-// NOTE: by default, we have #ifdef'ed out the TryLock() method.
-// This is for two reasons:
-// 1) TryLock() under Windows is a bit annoying (it requires a
-// #define to be defined very early).
-// 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG
-// mode.
-// If you need TryLock(), and either these two caveats are not a
-// problem for you, or you're willing to work around them, then
-// feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs
-// in the code below.
-//
-// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy:
-// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html
-// Because of that, we might as well use windows locks for
-// cygwin. They seem to be more reliable than the cygwin pthreads layer.
-//
-// TRICKY IMPLEMENTATION NOTE:
-// This class is designed to be safe to use during
-// dynamic-initialization -- that is, by global constructors that are
-// run before main() starts. The issue in this case is that
-// dynamic-initialization happens in an unpredictable order, and it
-// could be that someone else's dynamic initializer could call a
-// function that tries to acquire this mutex -- but that all happens
-// before this mutex's constructor has run. (This can happen even if
-// the mutex and the function that uses the mutex are in the same .cc
-// file.) Basically, because Mutex does non-trivial work in its
-// constructor, it's not, in the naive implementation, safe to use
-// before dynamic initialization has run on it.
-//
-// The solution used here is to pair the actual mutex primitive with a
-// bool that is set to true when the mutex is dynamically initialized.
-// (Before that it's false.) Then we modify all mutex routines to
-// look at the bool, and not try to lock/unlock until the bool makes
-// it to true (which happens after the Mutex constructor has run.)
-//
-// This works because before main() starts -- particularly, during
-// dynamic initialization -- there are no threads, so a) it's ok that
-// the mutex operations are a no-op, since we don't need locking then
-// anyway; and b) we can be quite confident our bool won't change
-// state between a call to Lock() and a call to Unlock() (that would
-// require a global constructor in one translation unit to call Lock()
-// and another global constructor in another translation unit to call
-// Unlock() later, which is pretty perverse).
-//
-// That said, it's tricky, and can conceivably fail; it's safest to
-// avoid trying to acquire a mutex in a global constructor, if you
-// can. One way it can fail is that a really smart compiler might
-// initialize the bool to true at static-initialization time (too
-// early) rather than at dynamic-initialization time. To discourage
-// that, we set is_safe_ to true in code (not the constructor
-// colon-initializer) and set it to true via a function that always
-// evaluates to true, but that the compiler can't know always
-// evaluates to true. This should be good enough.
-//
-// A related issue is code that could try to access the mutex
-// after it's been destroyed in the global destructors (because
-// the Mutex global destructor runs before some other global
-// destructor, that tries to acquire the mutex). The way we
-// deal with this is by taking a constructor arg that global
-// mutexes should pass in, that causes the destructor to do no
-// work. We still depend on the compiler not doing anything
-// weird to a Mutex's memory after it is destroyed, but for a
-// static global variable, that's pretty safe.

-// This file is needed for windows -- unittests are not part of the
-// gflags dll, but still want to include config.h just like the
-// dll does, so they can use internal tools and APIs for testing.
-//
-// The problem is that config.h declares GFLAGS_DLL_DECL to be
-// for exporting symbols, but the unittest needs to *import* symbols
-// (since it's not the dll).
-//
-// The solution is to have this file, which is just like config.h but
-// sets GFLAGS_DLL_DECL to do a dllimport instead of a dllexport.
-//
-// The reason we need this extra GFLAGS_DLL_DECL_FOR_UNITTESTS
-// variable is in case people want to set GFLAGS_DLL_DECL explicitly
-// to something other than __declspec(dllexport). In that case, they
-// may want to use something other than __declspec(dllimport) for the
-// unittest case. For that, we allow folks to define both
-// GFLAGS_DLL_DECL and GFLAGS_DLL_DECL_FOR_UNITTESTS explicitly.
-//
-// NOTE: This file is equivalent to config.h on non-windows systems,
-// which never defined GFLAGS_DLL_DECL_FOR_UNITTESTS and always
-// define GFLAGS_DLL_DECL to the empty string.

-
-<p>This is the heap checker we use at Google to detect memory leaks in
-C++ programs. There are three parts to using it: linking the library
-into an application, running the code, and analyzing the output.</p>
-
-
-<H1>Linking in the Library</H1>
-
-<p>The heap-checker is part of tcmalloc, so to install the heap
-checker into your executable, add <code>-ltcmalloc</code> to the
-link-time step for your executable. Also, while we don't necessarily
-recommend this form of usage, it's possible to add in the profiler at
-run-time using <code>LD_PRELOAD</code>:</p>
-<pre>% env LD_PRELOAD="/usr/lib/libtcmalloc.so" <binary></pre>
-
-<p>This does <i>not</i> turn on heap checking; it just inserts the
-code. For that reason, it's practical to just always link
-<code>-ltcmalloc</code> into a binary while developing; that's what we
-do at Google. (However, since any user can turn on the profiler by
-setting an environment variable, it's not necessarily recommended to
-install heapchecker-linked binaries into a production, running
-system.) Note that if you wish to use the heap checker, you must
-also use the tcmalloc memory-allocation library. There is no way
-currently to use the heap checker separate from tcmalloc.</p>
-
-
-<h1>Running the Code</h1>
-
-<p>Note: For security reasons, heap profiling will not write to a file
--- and is thus not usable -- for setuid programs.</p>
-
-<h2><a name="whole_program">Whole-program Heap Leak Checking</a></h2>
-
-<p>The recommended way to use the heap checker is in "whole program"
-mode. In this case, the heap-checker starts tracking memory
-allocations before the start of <code>main()</code>, and checks again
-at program-exit. If it finds any memory leaks -- that is, any memory
-not pointed to by objects that are still "live" at program-exit -- it
-aborts the program (via <code>exit(1)</code>) and prints a message
-describing how to track down the memory leak (using <A
-HREF="heapprofile.html#pprof">pprof</A>).</p>
-
-<p>The heap-checker records the stack trace for each allocation while
-it is active. This causes a significant increase in memory usage, in
-addition to slowing your program down.</p>
-
-<p>Here's how to run a program with whole-program heap checking:</p>
-
-<ol>
- <li> <p>Define the environment variable HEAPCHECK to the <A
- HREF="#types">type of heap-checking</A> to do. For instance,
- to heap-check
- <code>/usr/local/bin/my_binary_compiled_with_tcmalloc</code>:</p>
- <pre>% env HEAPCHECK=normal /usr/local/bin/my_binary_compiled_with_tcmalloc</pre>
-</ol>
-
-<p>No other action is required.</p>
-
-<p>Note that since the heap-checker uses the heap-profiling framework
-internally, it is not possible to run both the heap-checker and <A
-HREF="heapprofile.html">heap profiler</A> at the same time.</p>
-
-
-<h3><a name="types">Flavors of Heap Checking</a></h3>
-
-<p>These are the legal values when running a whole-program heap
-check:</p>
-<ol>
- <li> <code>minimal</code>
- <li> <code>normal</code>
- <li> <code>strict</code>
- <li> <code>draconian</code>
-</ol>
-
-<p>"Minimal" heap-checking starts as late as possible in a
-initialization, meaning you can leak some memory in your
-initialization routines (that run before <code>main()</code>, say),
-and not trigger a leak message. If you frequently (and purposefully)
-leak data in one-time global initializers, "minimal" mode is useful
-for you. Otherwise, you should avoid it for stricter modes.</p>
-
-<p>"Normal" heap-checking tracks <A HREF="#live">live objects</A> and
-reports a leak for any data that is not reachable via a live object
-when the program exits.</p>
-
-<p>"Strict" heap-checking is much like "normal" but has a few extra
-checks that memory isn't lost in global destructors. In particular,
-if you have a global variable that allocates memory during program
-execution, and then "forgets" about the memory in the global
-destructor (say, by setting the pointer to it to NULL) without freeing
-it, that will prompt a leak message in "strict" mode, though not in
-"normal" mode.</p>
-
-<p>"Draconian" heap-checking is appropriate for those who like to be
-very precise about their memory management, and want the heap-checker
-to help them enforce it. In "draconian" mode, the heap-checker does
-not do "live object" checking at all, so it reports a leak unless
-<i>all</i> allocated memory is freed before program exit. (However,
-you can use <A HREF="#disable">IgnoreObject()</A> to re-enable
-liveness-checking on an object-by-object basis.)</p>
-
-<p>"Normal" mode, as the name implies, is the one used most often at
-Google. It's appropriate for everyday heap-checking use.</p>
-
-<p>In addition, there are two other possible modes:</p>
-<ul>
- <li> <code>as-is</code>
- <li> <code>local</code>
-</ul>
-<p><code>as-is</code> is the most flexible mode; it allows you to
-specify the various <A HREF="#options">knobs</A> of the heap checker
-explicitly. <code>local</code> activates the <A
-HREF="#explicit">explicit heap-check instrumentation</A>, but does not
-turn on any whole-program leak checking.</p>
-
-
-<h3><A NAME="tweaking">Tweaking whole-program checking</A></h3>
-
-<p>In some cases you want to check the whole program for memory leaks,
-but waiting for after <code>main()</code> exits to do the first
-whole-program leak check is waiting too long: e.g. in a long-running
-server one might wish to simply periodically check for leaks while the
-server is running. In this case, you can call the static method
-<code>NoGlobalLeaks()</code>, to verify no global leaks have happened
-as of that point in the program.</p>
-
-<p>Alternately, doing the check after <code>main()</code> exits might
-be too late. Perhaps you have some objects that are known not to
-clean up properly at exit. You'd like to do the "at exit" check
-before those objects are destroyed (since while they're live, any
-memory they point to will not be considered a leak). In that case,
-you can call <code>NoGlobalLeaks()</code> manually, near the end of
-<code>main()</code>, and then call <code>CancelGlobalCheck()</code> to
-turn off the automatic post-<code>main()</code> check.</p>
-
-<p>Finally, there's a helper macro for "strict" and "draconian" modes,
-which require all global memory to be freed before program exit. This
-freeing can be time-consuming and is often unnecessary, since libc
-cleans up all memory at program-exit for you. If you want the
-benefits of "strict"/"draconian" modes without the cost of all that
-freeing, look at <code>REGISTER_HEAPCHECK_CLEANUP</code> (in
-<code>heap-checker.h</code>). This macro allows you to mark specific
-cleanup code as active only when the heap-checker is turned on.</p>
-
-
-<h2><a name="explicit">Explicit (Partial-program) Heap Leak Checking</h2>
-
-<p>Instead of whole-program checking, you can check certain parts of your
-code to verify they do not have memory leaks. This check verifies that
-between two parts of a program, no memory is allocated without being freed.</p>
-<p>To use this kind of checking code, bracket the code you want
-checked by creating a <code>HeapLeakChecker</code> object at the
-beginning of the code segment, and call
-<code>NoLeaks()</code> at the end. These functions, and all others
-referred to in this file, are declared in
-<code><gperftools/heap-checker.h></code>.
-</p>
-
-<p>Here's an example:</p>
-<pre>
- HeapLeakChecker heap_checker("test_foo");
- {
- code that exercises some foo functionality;
- this code should not leak memory;
- }
- if (!heap_checker.NoLeaks()) assert(NULL == "heap memory leak");
-</pre>
-
-<p>Note that adding in the <code>HeapLeakChecker</code> object merely
-instruments the code for leak-checking. To actually turn on this
-leak-checking on a particular run of the executable, you must still
-run with the heap-checker turned on:</p>
-<pre>% env HEAPCHECK=local /usr/local/bin/my_binary_compiled_with_tcmalloc</pre>
-<p>If you want to do whole-program leak checking in addition to this
-manual leak checking, you can run in <code>normal</code> or some other
-mode instead: they'll run the "local" checks in addition to the
-whole-program check.</p>
-
-
-<h2><a name="disable">Disabling Heap-checking of Known Leaks</a></h2>
-
-<p>Sometimes your code has leaks that you know about and are willing
-to accept. You would like the heap checker to ignore them when
-checking your program. You can do this by bracketing the code in
-question with an appropriate heap-checking construct:</p>
-<pre>
- ...
- {
- HeapLeakChecker::Disabler disabler;
- <leaky code>
- }
- ...
-</pre>
-Any objects allocated by <code>leaky code</code> (including inside any
-routines called by <code>leaky code</code>) and any objects reachable
-from such objects are not reported as leaks.
-
-<p>Alternately, you can use <code>IgnoreObject()</code>, which takes a
-pointer to an object to ignore. That memory, and everything reachable
-from it (by following pointers), is ignored for the purposes of leak
-checking. You can call <code>UnIgnoreObject()</code> to undo the
-effects of <code>IgnoreObject()</code>.</p>
-
-
-<h2><a name="options">Tuning the Heap Checker</h2>
-
-<p>The heap leak checker has many options, some that trade off running
-time and accuracy, and others that increase the sensitivity at the
-risk of returning false positives. For most uses, the range covered
-by the <A HREF="#types">heap-check flavors</A> is enough, but in
-specialized cases more control can be helpful.</p>
-
-<p>
-These options are specified via environment varaiables.
-</p>
-
-<p>This first set of options controls sensitivity and accuracy. These
-options are ignored unless you run the heap checker in <A
-HREF="#types">as-is</A> mode.

-<h2>Tips for Handling Detected Leaks</h2>
-
-<p>What do you do when the heap leak checker detects a memory leak?
-First, you should run the reported <code>pprof</code> command;
-hopefully, that is enough to track down the location where the leak
-occurs.</p>
-
-<p>If the leak is a real leak, you should fix it!</p>
-
-<p>If you are sure that the reported leaks are not dangerous and there
-is no good way to fix them, then you can use
-<code>HeapLeakChecker::Disabler</code> and/or
-<code>HeapLeakChecker::IgnoreObject()</code> to disable heap-checking
-for certain parts of the codebase.</p>
-
-<p>In "strict" or "draconian" mode, leaks may be due to incomplete
-cleanup in the destructors of global variables. If you don't wish to
-augment the cleanup routines, but still want to run in "strict" or
-"draconian" mode, consider using <A
-HREF="#tweaking"><code>REGISTER_HEAPCHECK_CLEANUP</code></A>.</p>
-
-<h2>Hints for Debugging Detected Leaks</h2>
-
-<p>Sometimes it can be useful to not only know the exact code that
-allocates the leaked objects, but also the addresses of the leaked objects.
-Combining this e.g. with additional logging in the program
-one can then track which subset of the allocations
-made at a certain spot in the code are leaked.
-<br/>
-To get the addresses of all leaked objects
- define the environment variable <code>HEAP_CHECK_IDENTIFY_LEAKS</code>
- to be <code>1</code>.
-The object addresses will be reported in the form of addresses
-of fake immediate callers of the memory allocation routines.
-Note that the performance of doing leak-checking in this mode
-can be noticeably worse than the default mode.
-</p>
-
-<p>One relatively common class of leaks that don't look real
-is the case of multiple initialization.
-In such cases the reported leaks are typically things that are
-linked from some global objects,
-which are initialized and say never modified again.
-The non-obvious cause of the leak is frequently the fact that
-the initialization code for these objects executes more than once.
-<br/>
-E.g. if the code of some <code>.cc</code> file is made to be included twice
-into the binary, then the constructors for global objects defined in that file
-will execute twice thus leaking the things allocated on the first run.
-<br/>
-Similar problems can occur if object initialization is done more explicitly
-e.g. on demand by a slightly buggy code
-that does not always ensure only-once initialization.
-</p>
-
-<p>
-A more rare but even more puzzling problem can be use of not properly
-aligned pointers (maybe inside of not properly aligned objects).
-Normally such pointers are not followed by the leak checker,
-hence the objects reachable only via such pointers are reported as leaks.
-If you suspect this case
- define the environment variable <code>HEAP_CHECK_TEST_POINTER_ALIGNMENT</code>
- to be <code>1</code>
-and then look closely at the generated leak report messages.
-</p>
-
-<h1>How It Works</h1>
-
-<p>When a <code>HeapLeakChecker</code> object is constructed, it dumps
-a memory-usage profile named
-<code><prefix>.<name>-beg.heap</code> to a temporary
-directory. When <code>NoLeaks()</code>
-is called (for whole-program checking, this happens automatically at
-program-exit), it dumps another profile, named
-<code><prefix>.<name>-end.heap</code>.
-(<code><prefix></code> is typically determined automatically,
-and <code><name></code> is typically <code>argv[0]</code>.) It
-then compares the two profiles. If the second profile shows
-more memory use than the first, the
-<code>NoLeaks()</code> function will
-return false. For "whole program" profiling, this will cause the
-executable to abort (via <code>exit(1)</code>). In all cases, it will
-print a message on how to process the dumped profiles to locate
-leaks.</p>
-
-<h3><A name=live>Detecting Live Objects</A></h3>
-
-<p>At any point during a program's execution, all memory that is
-accessible at that time is considered "live." This includes global
-variables, and also any memory that is reachable by following pointers
-from a global variable. It also includes all memory reachable from
-the current stack frame and from current CPU registers (this captures
-local variables). Finally, it includes the thread equivalents of
-these: thread-local storage and thread heaps, memory reachable from
-thread-local storage and thread heaps, and memory reachable from
-thread CPU registers.</p>
-
-<p>In all modes except "draconian," live memory is not
-considered to be a leak. We detect this by doing a liveness flood,
-traversing pointers to heap objects starting from some initial memory
-regions we know to potentially contain live pointer data. Note that
-this flood might potentially not find some (global) live data region
-to start the flood from. If you find such, please file a bug.</p>
-
-<p>The liveness flood attempts to treat any properly aligned byte
-sequences as pointers to heap objects and thinks that it found a good
-pointer whenever the current heap memory map contains an object with
-the address whose byte representation we found. Some pointers into
-not-at-start of object will also work here.</p>
-
-<p>As a result of this simple approach, it's possible (though
-unlikely) for the flood to be inexact and occasionally result in
-leaked objects being erroneously determined to be live. For instance,
-random bit patterns can happen to look like pointers to leaked heap
-objects. More likely, stale pointer data not corresponding to any
-live program variables can be still present in memory regions,
-especially in thread stacks. For instance, depending on how the local
-<code>malloc</code> is implemented, it may reuse a heap object
-address:</p>
-<pre>
- char* p = new char[1]; // new might return 0x80000000, say.
- delete p;
- new char[1]; // new might return 0x80000000 again
- // This last new is a leak, but doesn't seem it: p looks like it points to it
-</pre>
-
-<p>In other words, imprecisions in the liveness flood mean that for
-any heap leak check we might miss some memory leaks. This means that
-for local leak checks, we might report a memory leak in the local
-area, even though the leak actually happened before the
-<code>HeapLeakChecker</code> object was constructed. Note that for
-whole-program checks, a leak report <i>does</i> always correspond to a
-real leak (since there's no "before" to have created a false-live
-object).</p>
-
-<p>While this liveness flood approach is not very portable and not
-100% accurate, it works in most cases and saves us from writing a lot
-of explicit clean up code and other hassles when dealing with thread
-data.</p>
-
-
-<h3>Visualizing Leak with <code>pprof</code></h3>
-
-<p>
-The heap checker automatically prints basic leak info with stack traces of
-leaked objects' allocation sites, as well as a pprof command line that can be
-used to visualize the call-graph involved in these allocations.
-The latter can be much more useful for a human
-to see where/why the leaks happened, especially if the leaks are numerous.
-</p>
-
-<h3>Leak-checking and Threads</h3>
-
-<p>At the time of HeapLeakChecker's construction and during
-<code>NoLeaks()</code> calls, we grab a lock
-and then pause all other threads so other threads do not interfere
-with recording or analyzing the state of the heap.</p>
-
-<p>In general, leak checking works correctly in the presence of
-threads. However, thread stack data liveness determination (via
-<code>base/thread_lister.h</code>) does not work when the program is
-running under GDB, because the ptrace functionality needed for finding
-threads is already hooked to by GDB. Conversely, leak checker's
-ptrace attempts might also interfere with GDB. As a result, GDB can
-result in potentially false leak reports. For this reason, the
-heap-checker turns itself off when running under GDB.</p>
-
-<p>Also, <code>thread_lister</code> only works for Linux pthreads;
-leak checking is unlikely to handle other thread implementations
-correctly.</p>
-
-<p>As mentioned in the discussion of liveness flooding, thread-stack
-liveness determination might mis-classify as reachable objects that
-very recently became unreachable (leaked). This can happen when the
-pointers to now-logically-unreachable objects are present in the
-active thread stack frame. In other words, trivial code like the
-following might not produce the expected leak checking outcome
-depending on how the compiled code works with the stack:</p>
-<pre>
- int* foo = new int [20];
- HeapLeakChecker check("a_check");
- foo = NULL;
- // May fail to trigger.
- if (!heap_checker.NoLeaks()) assert(NULL == "heap memory leak");
-</pre>

-
-<p>This is the heap profiler we use at Google, to explore how C++
-programs manage memory. This facility can be useful for</p>
-<ul>
- <li> Figuring out what is in the program heap at any given time
- <li> Locating memory leaks
- <li> Finding places that do a lot of allocation
-</ul>
-
-<p>The profiling system instruments all allocations and frees. It
-keeps track of various pieces of information per allocation site. An
-allocation site is defined as the active stack trace at the call to
-<code>malloc</code>, <code>calloc</code>, <code>realloc</code>, or,
-<code>new</code>.</p>
-
-<p>There are three parts to using it: linking the library into an
-application, running the code, and analyzing the output.</p>
-
-
-<h1>Linking in the Library</h1>
-
-<p>To install the heap profiler into your executable, add
-<code>-ltcmalloc</code> to the link-time step for your executable.
-Also, while we don't necessarily recommend this form of usage, it's
-possible to add in the profiler at run-time using
-<code>LD_PRELOAD</code>:
-<pre>% env LD_PRELOAD="/usr/lib/libtcmalloc.so" <binary></pre>
-
-<p>This does <i>not</i> turn on heap profiling; it just inserts the
-code. For that reason, it's practical to just always link
-<code>-ltcmalloc</code> into a binary while developing; that's what we
-do at Google. (However, since any user can turn on the profiler by
-setting an environment variable, it's not necessarily recommended to
-install profiler-linked binaries into a production, running
-system.) Note that if you wish to use the heap profiler, you must
-also use the tcmalloc memory-allocation library. There is no way
-currently to use the heap profiler separate from tcmalloc.</p>
-
-
-<h1>Running the Code</h1>
-
-<p>There are several alternatives to actually turn on heap profiling
-for a given run of an executable:</p>
-
-<ol>
- <li> <p>Define the environment variable HEAPPROFILE to the filename
- to dump the profile to. For instance, to profile
- <code>/usr/local/bin/my_binary_compiled_with_tcmalloc</code>:</p>
- <pre>% env HEAPPROFILE=/tmp/mybin.hprof /usr/local/bin/my_binary_compiled_with_tcmalloc</pre>
- <li> <p>In your code, bracket the code you want profiled in calls to
- <code>HeapProfilerStart()</code> and <code>HeapProfilerStop()</code>.
- (These functions are declared in <code><gperftools/heap-profiler.h></code>.)
- <code>HeapProfilerStart()</code> will take the
- profile-filename-prefix as an argument. Then, as often as
- you'd like before calling <code>HeapProfilerStop()</code>, you
- can use <code>HeapProfilerDump()</code> or
- <code>GetHeapProfile()</code> to examine the profile. In case
- it's useful, <code>IsHeapProfilerRunning()</code> will tell you
- whether you've already called HeapProfilerStart() or not.</p>
-</ol>
-
-
-<p>For security reasons, heap profiling will not write to a file --
-and is thus not usable -- for setuid programs.</p>
-
-<H2>Modifying Runtime Behavior</H2>
-
-<p>You can more finely control the behavior of the heap profiler via
-environment variables.</p>

-<H2>Checking for Leaks</H2>
-
-<p>You can use the heap profiler to manually check for leaks, for
-instance by reading the profiler output and looking for large
-allocations. However, for that task, it's easier to use the <A
-HREF="heap_checker.html">automatic heap-checking facility</A> built
-into tcmalloc.</p>
-
-
-<h1><a name="pprof">Analyzing the Output</a></h1>
-
-<p>If heap-profiling is turned on in a program, the program will
-periodically write profiles to the filesystem. The sequence of
-profiles will be named:</p>
-<pre>
- <prefix>.0000.heap
- <prefix>.0001.heap
- <prefix>.0002.heap
- ...
-</pre>
-<p>where <code><prefix></code> is the filename-prefix supplied
-when running the code (e.g. via the <code>HEAPPROFILE</code>
-environment variable). Note that if the supplied prefix
-does not start with a <code>/</code>, the profile files will be
-written to the program's working directory.</p>
-
-<p>The profile output can be viewed by passing it to the
-<code>pprof</code> tool -- the same tool that's used to analyze <A
-HREF="cpuprofile.html">CPU profiles</A>.
-
-<p>Here are some examples. These examples assume the binary is named
-<code>gfs_master</code>, and a sequence of heap profile files can be
-found in files named:</p>
-<pre>
- /tmp/profile.0001.heap
- /tmp/profile.0002.heap
- ...
- /tmp/profile.0100.heap
-</pre>
-
-<h3>Why is a process so big</h3>
-
-<pre>
- % pprof --gv gfs_master /tmp/profile.0100.heap
-</pre>
-
-<p>This command will pop-up a <code>gv</code> window that displays
-the profile information as a directed graph. Here is a portion
-of the resulting output:</p>
-
-<p><center>
-<img src="heap-example1.png">
-</center></p>
-
-A few explanations:
-<ul>
-<li> <code>GFS_MasterChunk::AddServer</code> accounts for 255.6 MB
- of the live memory, which is 25% of the total live memory.
-<li> <code>GFS_MasterChunkTable::UpdateState</code> is directly
- accountable for 176.2 MB of the live memory (i.e., it directly
- allocated 176.2 MB that has not been freed yet). Furthermore,
- it and its callees are responsible for 729.9 MB. The
- labels on the outgoing edges give a good indication of the
- amount allocated by each callee.
-</ul>
-
-<h3>Comparing Profiles</h3>
-
-<p>You often want to skip allocations during the initialization phase
-of a program so you can find gradual memory leaks. One simple way to
-do this is to compare two profiles -- both collected after the program
-has been running for a while. Specify the name of the first profile
-using the <code>--base</code> option. For example:</p>
-<pre>
- % pprof --base=/tmp/profile.0004.heap gfs_master /tmp/profile.0100.heap
-</pre>
-
-<p>The memory-usage in <code>/tmp/profile.0004.heap</code> will be
-subtracted from the memory-usage in
-<code>/tmp/profile.0100.heap</code> and the result will be
-displayed.</p>
-
-<h3>Text display</h3>
-
-<pre>
-% pprof --text gfs_master /tmp/profile.0100.heap
- 255.6 24.7% 24.7% 255.6 24.7% GFS_MasterChunk::AddServer
- 184.6 17.8% 42.5% 298.8 28.8% GFS_MasterChunkTable::Create
- 176.2 17.0% 59.5% 729.9 70.5% GFS_MasterChunkTable::UpdateState
- 169.8 16.4% 75.9% 169.8 16.4% PendingClone::PendingClone
- 76.3 7.4% 83.3% 76.3 7.4% __default_alloc_template::_S_chunk_alloc
- 49.5 4.8% 88.0% 49.5 4.8% hashtable::resize
- ...
-</pre>
-
-<p>
-<ul>
- <li> The first column contains the direct memory use in MB.
- <li> The fourth column contains memory use by the procedure
- and all of its callees.
- <li> The second and fifth columns are just percentage
- representations of the numbers in the first and fourth columns.
- <li> The third column is a cumulative sum of the second column
- (i.e., the <code>k</code>th entry in the third column is the
- sum of the first <code>k</code> entries in the second column.)
-</ul>
-
-<h3>Ignoring or focusing on specific regions</h3>
-
-<p>The following command will give a graphical display of a subset of
-the call-graph. Only paths in the call-graph that match the regular
-expression <code>DataBuffer</code> are included:</p>
-<pre>
-% pprof --gv --focus=DataBuffer gfs_master /tmp/profile.0100.heap
-</pre>
-
-<p>Similarly, the following command will omit all paths subset of the
-call-graph. All paths in the call-graph that match the regular
-expression <code>DataBuffer</code> are discarded:</p>
-<pre>
-% pprof --gv --ignore=DataBuffer gfs_master /tmp/profile.0100.heap
-</pre>
-
-<h3>Total allocations + object-level information</h3>
-
-<p>All of the previous examples have displayed the amount of in-use
-space. I.e., the number of bytes that have been allocated but not
-freed. You can also get other types of information by supplying a
-flag to <code>pprof</code>:</p>
-
-<center>
-<table frame=box rules=sides cellpadding=5 width=100%>
-
-<tr valign=top>
- <td><code>--inuse_space</code></td>
- <td>
- Display the number of in-use megabytes (i.e. space that has
- been allocated but not freed). This is the default.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>--inuse_objects</code></td>
- <td>
- Display the number of in-use objects (i.e. number of
- objects that have been allocated but not freed).
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>--alloc_space</code></td>
- <td>
- Display the number of allocated megabytes. This includes
- the space that has since been de-allocated. Use this
- if you want to find the main allocation sites in the
- program.
- </td>
-</tr>
-
-<tr valign=top>
- <td><code>--alloc_objects</code></td>
- <td>
- Display the number of allocated objects. This includes
- the objects that have since been de-allocated. Use this
- if you want to find the main allocation sites in the
- program.
- </td>
-
-</table>
-</center>
-
-
-<h3>Interactive mode</a></h3>
-
-<p>By default -- if you don't specify any flags to the contrary --
-pprof runs in interactive mode. At the <code>(pprof)</code> prompt,
-you can run many of the commands described above. You can type
-<code>help</code> for a list of what commands are available in
-interactive mode.</p>
-
-
-<h1>Caveats</h1>
-
-<ul>
- <li> Heap profiling requires the use of libtcmalloc. This
- requirement may be removed in a future version of the heap
- profiler, and the heap profiler separated out into its own
- library.
-
- <li> If the program linked in a library that was not compiled
- with enough symbolic information, all samples associated
- with the library may be charged to the last symbol found
- in the program before the library. This will artificially
- inflate the count for that symbol.
-
- <li> If you run the program on one machine, and profile it on
- another, and the shared libraries are different on the two
- machines, the profiling output may be confusing: samples that
- fall within the shared libaries may be assigned to arbitrary
- procedures.
-
- <li> Several libraries, such as some STL implementations, do their
- own memory management. This may cause strange profiling
- results. We have code in libtcmalloc to cause STL to use
- tcmalloc for memory management (which in our tests is better
- than STL's internal management), though it only works for some
- STL implementations.
-
- <li> If your program forks, the children will also be profiled
- (since they inherit the same HEAPPROFILE setting). Each
- process is profiled separately; to distinguish the child
- profiles from the parent profile and from each other, all
- children will have their process-id attached to the HEAPPROFILE
- name.
-
- <li> Due to a hack we make to work around a possible gcc bug, your
- profiles may end up named strangely if the first character of
- your HEAPPROFILE variable has ascii value greater than 127.
- This should be exceedingly rare, but if you need to use such a
- name, just set prepend <code>./</code> to your filename:
- <code>HEAPPROFILE=./Ägypten</code>.

-<BODY>

-<h1><code>pprof</code> and Remote Servers</h1>
-
-<p>In mid-2006, we added an experimental facility to <A
-HREF="cpu_profiler.html">pprof</A>, the tool that analyzes CPU and
-heap profiles. This facility allows you to collect profile
-information from running applications. It makes it easy to collect
-profile information without having to stop the program first, and
-without having to log into the machine where the application is
-running. This is meant to be used on webservers, but will work on any
-application that can be modified to accept TCP connections on a port
-of its choosing, and to respond to HTTP requests on that port.</p>
-
-<p>We do not currently have infrastructure, such as apache modules,
-that you can pop into a webserver or other application to get the
-necessary functionality "for free." However, it's easy to generate
-the necessary data, which should allow the interested developer to add
-the necessary support into his or her applications.</p>
-
-<p>To use <code>pprof</code> in this experimental "server" mode, you
-give the script a host and port it should query, replacing the normal
-commandline arguments of application + profile file:</p>
-<pre>
- % pprof internalweb.mycompany.com:80
-</pre>
-
-<p>The host must be listening on that port, and be able to accept HTTP/1.0
-requests -- sent via <code>wget</code> and <code>curl</code> -- for
-several urls. The following sections list the urls that
-<code>pprof</code> can send, and the responses it expects in
-return.</p>
-
-<p>Here are examples that pprof will recognize, when you give them
-on the commandline, are urls. In general, you
-specify the host and a port (the port-number is required), and put
-the service-name at the end of the url.:</p>
-<blockquote><pre>
-http://myhost:80/pprof/heap # retrieves a heap profile
-http://myhost:8008/pprof/profile # retrieves a CPU profile
-http://myhost:80 # retrieves a CPU profile (the default)
-http://myhost:8080/ # retrieves a CPU profile (the default)
-myhost:8088/pprof/growth # "http://" is optional, but port is not
-http://myhost:80/myservice/pprof/heap # /pprof/heap just has to come at the end
-http://myhost:80/pprof/pmuprofile # CPU profile using performance counters
-</pre></blockquote>
-
-<h2> <code><b>/pprof/heap</b></code> </h2>
-
-<p><code>pprof</code> asks for the url <code>/pprof/heap</code> to
-get heap information. The actual url is controlled via the variable
-<code>HEAP_PAGE</code> in the <code>pprof</code> script, so you
-can change it if you'd like.</p>
-
-<p>There are two ways to get this data. The first is to call</p>
-<pre>
- MallocExtension::instance()->GetHeapSample(&output);
-</pre>
-<p>and have the server send <code>output</code> back as an HTTP
-response to <code>pprof</code>. <code>MallocExtension</code> is
-defined in the header file <code>gperftools/malloc_extension.h</code>.</p>
-
-<p>Note this will only only work if the binary is being run with
-sampling turned on (which is not the default). To do this, set the
-environment variable <code>TCMALLOC_SAMPLE_PARAMETER</code> to a
-positive value, such as 524288, before running.</p>
-
-<p>The other way is to call <code>HeapProfileStart(filename)</code>
-(from <code>heap-profiler.h</code>), continue to do work, and then,
-some number of seconds later, call <code>GetHeapProfile()</code>
-(followed by <code>HeapProfilerStop()</code>). The server can send
-the output of <code>GetHeapProfile</code> back as the HTTP response to
-pprof. (Note you must <code>free()</code> this data after using it.)
-This is similar to how <A HREF="#profile">profile requests</A> are
-handled, below. This technique does not require the application to
-run with sampling turned on.</p>
-
-<p>Here's an example of what the output should look like:</p>
-<pre>
-heap profile: 1923: 127923432 [ 1923: 127923432] @ heap_v2/524288
- 1: 312 [ 1: 312] @ 0x2aaaabaf5ccc 0x2aaaaba4cd2c 0x2aaaac08c09a
- 928: 122586016 [ 928: 122586016] @ 0x2aaaabaf682c 0x400680 0x400bdd 0x2aaaab1c368a 0x2aaaab1c8f77 0x2aaaab1c0396 0x2aaaab1c86ed 0x4007ff 0x2aaaaca62afa
- 1: 16 [ 1: 16] @ 0x2aaaabaf5ccc 0x2aaaabb04bac 0x2aaaabc1b262 0x2aaaabc21496 0x2aaaabc214bb
-[...]
-</pre>
-
-
-<p> Older code may produce "version 1" heap profiles which look like this:<p/>
-<pre>
-heap profile: 14933: 791700132 [ 14933: 791700132] @ heap
- 1: 848688 [ 1: 848688] @ 0xa4b142 0x7f5bfc 0x87065e 0x4056e9 0x4125f8 0x42b4f1 0x45b1ba 0x463248 0x460871 0x45cb7c 0x5f1744 0x607cee 0x5f4a5e 0x40080f 0x2aaaabad7afa
- 1: 1048576 [ 1: 1048576] @ 0xa4a9b2 0x7fd025 0x4ca6d8 0x4ca814 0x4caa88 0x2aaaab104cf0 0x404e20 0x4125f8 0x42b4f1 0x45b1ba 0x463248 0x460871 0x45cb7c 0x5f1744 0x607cee 0x5f4a5e 0x40080f 0x2aaaabad7afa
- 2942: 388629374 [ 2942: 388629374] @ 0xa4b142 0x4006a0 0x400bed 0x5f0cfa 0x5f1744 0x607cee 0x5f4a5e 0x40080f 0x2aaaabad7afa
-[...]
-</pre>
-<p>pprof accepts both old and new heap profiles and automatically
-detects which one you are using.</p>
-
-<h2> <code><b>/pprof/growth</b></code> </h2>
-
-<p><code>pprof</code> asks for the url <code>/pprof/growth</code> to
-get heap-profiling delta (growth) information. The actual url is
-controlled via the variable <code>GROWTH_PAGE</code> in the
-<code>pprof</code> script, so you can change it if you'd like.</p>
-
-<p>The server should respond by calling</p>
-<pre>
- MallocExtension::instance()->GetHeapGrowthStacks(&output);
-</pre>
-<p>and sending <code>output</code> back as an HTTP response to
-<code>pprof</code>. <code>MallocExtension</code> is defined in the
-header file <code>gperftools/malloc_extension.h</code>.</p>
-
-<p>Here's an example, from an actual Google webserver, of what the
-output should look like:</p>
-<pre>
-heap profile: 741: 812122112 [ 741: 812122112] @ growth
- 1: 1572864 [ 1: 1572864] @ 0x87da564 0x87db8a3 0x84787a4 0x846e851 0x836d12f 0x834cd1c 0x8349ba5 0x10a3177 0x8349961
- 1: 1048576 [ 1: 1048576] @ 0x87d92e8 0x87d9213 0x87d9178 0x87d94d3 0x87da9da 0x8a364ff 0x8a437e7 0x8ab7d23 0x8ab7da9 0x8ac7454 0x8348465 0x10a3161 0x8349961
-[...]
-</pre>
-
-
-<h2> <A NAME="profile"><code><b>/pprof/profile</b></code></A> </h2>
-
-<p><code>pprof</code> asks for the url
-<code>/pprof/profile?seconds=XX</code> to get cpu-profiling
-information. The actual url is controlled via the variable
-<code>PROFILE_PAGE</code> in the <code>pprof</code> script, so you can
-change it if you'd like.</p>
-
-<p>The server should respond by calling
-<code>ProfilerStart(filename)</code>, continuing to do its work, and
-then, XX seconds later, calling <code>ProfilerStop()</code>. (These
-functions are declared in <code>gperftools/profiler.h</code>.) The
-application is responsible for picking a unique filename for
-<code>ProfilerStart()</code>. After calling
-<code>ProfilerStop()</code>, the server should read the contents of
-<code>filename</code> and send them back as an HTTP response to
-<code>pprof</code>.</p>
-
-<p>Obviously, to get useful profile information the application must
-continue to run in the XX seconds that the profiler is running. Thus,
-the profile start-stop calls should be done in a separate thread, or
-be otherwise non-blocking.</p>
-
-<p>The profiler output file is binary, but near the end of it, it
-should have lines of text somewhat like this:</p>
-<pre>
-01016000-01017000 rw-p 00015000 03:01 59314 /lib/ld-2.2.2.so
-</pre>
-
-<h2> <code><b>/pprof/pmuprofile</b></code> </h2>
-
-<code>pprof</code> asks for a url of the form
-<code>/pprof/pmuprofile?event=hw_event:unit_mask&period=nnn&seconds=xxx</code>
-to get cpu-profiling information. The actual url is controlled via the variable
-<code>PMUPROFILE_PAGE</code> in the <code>pprof</code> script, so you can
-change it if you'd like.</p>
-
-<p>
-This is similar to pprof, but is meant to be used with your CPU's hardware
-performance counters. The server could be implemented on top of a library
-such as <a href="http://perfmon2.sourceforge.net/">
-<code>libpfm</code></a>. It should collect a sample every nnn occurrences
-of the event and stop the sampling after xxx seconds. Much of the code
-for <code>/pprof/profile</code> can be reused for this purpose.
-</p>
-
-<p>The server side routines (the equivalent of
-ProfilerStart/ProfilerStart) are not available as part of perftools,
-so this URL is unlikely to be that useful.</p>
-
-<h2> <code><b>/pprof/contention</b></code> </h2>
-
-<p>This is intended to be able to profile (thread) lock contention in
-addition to CPU and memory use. It's not yet usable.</p>
-
-
-<h2> <code><b>/pprof/cmdline</b></code> </h2>
-
-<p><code>pprof</code> asks for the url <code>/pprof/cmdline</code> to
-figure out what application it's profiling. The actual url is
-controlled via the variable <code>PROGRAM_NAME_PAGE</code> in the
-<code>pprof</code> script, so you can change it if you'd like.</p>
-
-<p>The server should respond by reading the contents of
-<code>/proc/self/cmdline</code>, converting all internal NUL (\0)
-characters to newlines, and sending the result back as an HTTP
-response to <code>pprof</code>.</p>
-
-<p>Here's an example return value:<p>
-<pre>
-/root/server/custom_webserver
-80
---configfile=/root/server/ws.config
-</pre>
-
-
-<h2> <code><b>/pprof/symbol</b></code> </h2>
-
-<p><code>pprof</code> asks for the url <code>/pprof/symbol</code> to
-map from hex addresses to variable names. The actual url is
-controlled via the variable <code>SYMBOL_PAGE</code> in the
-<code>pprof</code> script, so you can change it if you'd like.</p>
-
-<p>When the server receives a GET request for
-<code>/pprof/symbol</code>, it should return a line formatted like
-so:</p>
-<pre>
- num_symbols: ###
-</pre>
-<p>where <code>###</code> is the number of symbols found in the
-binary. (For now, the only important distinction is whether the value
-is 0, which it is for executables that lack debug information, or
-not-0).</p>
-
-<p>This is perhaps the hardest request to write code for, because in
-addition to the GET request for this url, the server must accept POST
-requests. This means that after the HTTP headers, pprof will pass in
-a list of hex addresses connected by <code>+</code>, like so:</p>
-<pre>
- curl -d '0x0824d061+0x0824d1cf' http://remote_host:80/pprof/symbol
-</pre>
-
-<p>The server should read the POST data, which will be in one line,
-and for each hex value, should write one line of output to the output
-stream, like so:</p>
-<pre>
-<hex address><tab><function name>
-</pre>
-<p>For instance:</p>
-<pre>
-0x08b2dabd _Update
-</pre>
-
-<p>The other reason this is the most difficult request to implement,
-is that the application will have to figure out for itself how to map
-from address to function name. One possibility is to run <code>nm -C
--n <program name></code> to get the mappings at
-program-compile-time. Another, at least on Linux, is to call out to
-addr2line for every <code>pprof/symbol</code> call, for instance
-<code>addr2line -Cfse /proc/<getpid>/exe 0x12345678 0x876543210</code>
-(presumably with some caching!)</p>
-
-<p><code>pprof</code> itself does just this for local profiles (not
-ones that talk to remote servers); look at the subroutine
-<code>GetProcedureBoundaries</code>.</p>

- they will rot your brain.
-
- The assembly code sequences for all architectures is in this one
- file. This is because this file must be stand-alone, and we don't
- want to have multiple files.
-
- For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
- value gets put in the return slot, so that everything works when
- this is executed not under Valgrind. Args are passed in a memory
- block, and so there's no intrinsic limit to the number that could
- be passed, but it's currently five.
-
- The macro args are:
- _zzq_rlval result lvalue
- _zzq_default default value (result returned when running on real CPU)
- _zzq_request request code
- _zzq_arg1..5 request params
-
- The other two macros are used to support function wrapping, and are
- a lot simpler. VALGRIND_GET_NR_CONTEXT returns the value of the
- guest's NRADDR pseudo-register and whatever other information is
- needed to safely run the call original from the wrapper: on
- ppc64-linux, the R2 value at the divert point is also needed. This
- information is abstracted into a user-visible type, OrigFn.
-
- VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
- guest, but guarantees that the branch instruction will not be
- redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
- branch-and-link-to-r11. VALGRIND_CALL_NOREDIR is just text, not a
- complete inline asm, since it needs to be combined with more magic
- inline asm stuff to be useful.

-/* This section defines magic (a.k.a appalling-hack) macros for doing
- guaranteed-no-redirection macros, so as to get from function
- wrappers to the functions they are wrapping. The whole point is to
- construct standard call sequences, but to do the call itself with a
- special no-redirect call pseudo-instruction that the JIT
- understands and handles specially. This section is long and
- repetitious, and I can't see a way to make it shorter.
-
- The naming scheme is as follows:
-
- CALL_FN_{W,v}_{v,W,WW,WWW,WWWW,5W,6W,7W,etc}
-
- 'W' stands for "word" and 'v' for "void". Hence there are
- different macros for calling arity 0, 1, 2, 3, 4, etc, functions,
- and for each, the possibility of returning a word-typed result, or
- no result.

- nastyness is that it is only by luck that the stack still appears
- to be unwindable during the hidden call - since then the behaviour
- of any routine using this macro does not match what the CFI data
- says. Sigh.
-
- Why is this important? Imagine that a wrapper has a stack
- allocated local, and passes to the hidden call, a pointer to it.
- Because gcc does not know about the hidden call, it may allocate
- that local in the redzone. Unfortunately the hidden call may then
- trash it before it comes to use it. So we must step clear of the
- redzone, for the duration of the hidden call, to make it safe.
-
- Probably the same problem afflicts the other redzone-style ABIs too
- (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
- self describing (none of this CFI nonsense) so at least messing
- with the stack pointer doesn't give a danger of non-unwindable
- stack. */

-// For atomic operations on reference counts, see atomic_refcount.h.
-
-// Some fast atomic operations -- typically with machine-dependent
-// implementations. This file may need editing as Google code is
-// ported to different architectures.
-
-// The routines exported by this module are subtle. If you use them, even if
-// you get the code right, it will depend on careful reasoning about atomicity
-// and memory ordering; it will be less readable, and harder to maintain. If
-// you plan to use these routines, you should have a good reason, such as solid
-// evidence that performance would otherwise suffer, or there being no
-// alternative. You should assume only properties explicitly guaranteed by the
-// specifications in this file. You are almost certainly _not_ writing code
-// just for the x86; if you assume x86 semantics, x86 hardware bugs and
-// implementations on other archtectures will cause your code to break. If you
-// do not know what you are doing, avoid these routines, and use a Mutex.
-//
-// These following lower-level operations are typically useful only to people
-// implementing higher-level synchronization operations like spinlocks,
-// mutexes, and condition-variables. They combine CompareAndSwap(), a load, or
-// a store with appropriate memory-ordering instructions. "Acquire" operations
-// ensure that no later memory access can be reordered ahead of the operation.
-// "Release" operations ensure that no previous memory access can be reordered
-// after the operation. "Barrier" operations have both "Acquire" and "Release"
-// semantics. A MemoryBarrier() has "Barrier" semantics, but does no memory
-// access.
-//
-// It is incorrect to make direct assignments to/from an atomic variable.
-// You should use one of the Load or Store routines. The NoBarrier
-// versions are provided when no barriers are needed:
-// NoBarrier_Store()
-// NoBarrier_Load()
-// Although there are currently no compiler enforcement, you are encouraged
-// to use these. Moreover, if you choose to use base::subtle::Atomic64 type,
-// you MUST use one of the Load or Store routines to get correct behavior
-// on 32-bit platforms.
-//
-// The intent is eventually to put all of these routines in namespace
-// base::subtle

-//

-//
-// The second argument to the macro is the name of the variable. If
-// the expression is false, most compilers will issue a warning/error
-// containing the name of the variable.
-//
-// Implementation details of COMPILE_ASSERT:
-//
-// - COMPILE_ASSERT works by defining an array type that has -1
-// elements (and thus is invalid) when the expression is false.
-//
-// - The simpler definition
-//
-// #define COMPILE_ASSERT(expr, msg) typedef char msg[(expr) ? 1 : -1]
-//
-// does not work, as gcc supports variable-length arrays whose sizes
-// are determined at run-time (this is gcc's extension and not part
-// of the C++ standard). As a result, gcc fails to reject the
-// following code with the simple definition:
-//
-// int foo;
-// COMPILE_ASSERT(foo, msg); // not supposed to compile as foo is
-// // not a compile-time constant.
-//
-// - By using the type CompileAssert<(bool(expr))>, we ensures that
-// expr is a compile-time constant. (Template arguments must be
-// determined at compile-time.)
-//
-// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
-// to work around a bug in gcc 3.4.4 and 4.0.1. If we had written
-//
-// CompileAssert<bool(expr)>
-//
-// instead, these compilers will refuse to compile
-//
-// COMPILE_ASSERT(5 > 0, some_message);
-//
-// (They seem to think the ">" in "5 > 0" marks the end of the
-// template argument list.)
-//
-// - The array size is (bool(expr) ? 1 : -1), instead of simply
-//
-// ((expr) ? 1 : -1).
-//
-// This is to avoid running into a bug in MS VC 7.1, which
-// causes ((0.0) ? 1 : -1) to incorrectly evaluate to 1.

-// This file is a compatibility layer that defines Google's version of
-// command line flags that are used for configuration.
-//
-// We put flags into their own namespace. It is purposefully
-// named in an opaque way that people should have trouble typing
-// directly. The idea is that DEFINE puts the flag in the weird
-// namespace, and DECLARE imports the flag from there into the
-// current namespace. The net result is to force people to use
-// DECLARE to get access to a flag, rather than saying
-// extern bool FLAGS_logtostderr;
-// or some such instead. We want this so we can put extra
-// functionality (like sanity-checking) in DECLARE if we want,
-// and make sure it is picked up everywhere.
-//
-// We also put the type of the variable in the namespace, so that
-// people can't DECLARE_int32 something that they DEFINE_bool'd
-// elsewhere.

-// A simple mutex wrapper, supporting locks and read-write locks.
-// You should assume the locks are *not* re-entrant.
-//
-// To use: you should define the following macros in your configure.ac:
-// ACX_PTHREAD
-// AC_RWLOCK
-// The latter is defined in ../autoconf.
-//
-// This class is meant to be internal-only and should be wrapped by an
-// internal namespace. Before you use this module, please give the
-// name of your internal namespace for this module. Or, if you want
-// to expose it, you'll want to move it to the Google namespace. We
-// cannot put this class in global namespace because there can be some
-// problems when we have multiple versions of Mutex in each shared object.
-//
-// NOTE: TryLock() is broken for NO_THREADS mode, at least in NDEBUG
-// mode.
-//
-// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy:
-// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html
-// Because of that, we might as well use windows locks for
-// cygwin. They seem to be more reliable than the cygwin pthreads layer.
-//
-// TRICKY IMPLEMENTATION NOTE:
-// This class is designed to be safe to use during
-// dynamic-initialization -- that is, by global constructors that are
-// run before main() starts. The issue in this case is that
-// dynamic-initialization happens in an unpredictable order, and it
-// could be that someone else's dynamic initializer could call a
-// function that tries to acquire this mutex -- but that all happens
-// before this mutex's constructor has run. (This can happen even if
-// the mutex and the function that uses the mutex are in the same .cc
-// file.) Basically, because Mutex does non-trivial work in its
-// constructor, it's not, in the naive implementation, safe to use
-// before dynamic initialization has run on it.
-//
-// The solution used here is to pair the actual mutex primitive with a
-// bool that is set to true when the mutex is dynamically initialized.
-// (Before that it's false.) Then we modify all mutex routines to
-// look at the bool, and not try to lock/unlock until the bool makes
-// it to true (which happens after the Mutex constructor has run.)
-//
-// This works because before main() starts -- particularly, during
-// dynamic initialization -- there are no threads, so a) it's ok that
-// the mutex operations are a no-op, since we don't need locking then
-// anyway; and b) we can be quite confident our bool won't change
-// state between a call to Lock() and a call to Unlock() (that would
-// require a global constructor in one translation unit to call Lock()
-// and another global constructor in another translation unit to call
-// Unlock() later, which is pretty perverse).
-//
-// That said, it's tricky, and can conceivably fail; it's safest to
-// avoid trying to acquire a mutex in a global constructor, if you
-// can. One way it can fail is that a really smart compiler might
-// initialize the bool to true at static-initialization time (too
-// early) rather than at dynamic-initialization time. To discourage
-// that, we set is_safe_ to true in code (not the constructor
-// colon-initializer) and set it to true via a function that always
-// evaluates to true, but that the compiler can't know always
-// evaluates to true. This should be good enough.
-//
-// A related issue is code that could try to access the mutex
-// after it's been destroyed in the global destructors (because
-// the Mutex global destructor runs before some other global
-// destructor, that tries to acquire the mutex). The way we
-// deal with this is by taking a constructor arg that global
-// mutexes should pass in, that causes the destructor to do no
-// work. We still depend on the compiler not doing anything
-// weird to a Mutex's memory after it is destroyed, but for a
-// static global variable, that's pretty safe.

-// Running:
-// ./heap-checker_unittest
-//
-// If the unittest crashes because it can't find pprof, try:
-// PPROF_PATH=/usr/local/someplace/bin/pprof ./heap-checker_unittest
-//
-// To test that the whole-program heap checker will actually cause a leak, try:
-// HEAPCHECK_TEST_LEAK= ./heap-checker_unittest
-// HEAPCHECK_TEST_LOOP_LEAK= ./heap-checker_unittest
-//
-// Note: Both of the above commands *should* abort with an error message.
-
-// CAVEAT: Do not use vector<> and string on-heap objects in this test,
-// otherwise the test can sometimes fail for tricky leak checks
-// when we want some allocated object not to be found live by the heap checker.
-// This can happen with memory allocators like tcmalloc that can allocate
-// heap objects back to back without any book-keeping data in between.
-// What happens is that end-of-storage pointers of a live vector
-// (or a string depending on the STL implementation used)
-// can happen to point to that other heap-allocated
-// object that is not reachable otherwise and that
-// we don't want to be reachable.
-//
-// The implication of this for real leak checking
-// is just one more chance for the liveness flood to be inexact
-// (see the comment in our .h file).

-<h1>Google CPU Profiler Binary Data File Format</h1>
-
-<p align=right>
- <i>Last modified
- <script type=text/javascript>
- var lm = new Date(document.lastModified);
- document.write(lm.toDateString());
- </script></i>
-</p>
-
-<p>This file documents the binary data file format produced by the
-Google CPU Profiler. For information about using the CPU Profiler,
-see <a href="cpuprofile.html">its user guide</a>.
-
-<p>The profiler source code, which generates files using this format, is at
-<code>src/profiler.cc</code></a>.
-
-
-<h2>CPU Profile Data File Structure</h2>
-
-<p>CPU profile data files each consist of four parts, in order:
-
-<ul>
- <li> Binary header
- <li> Binary profile records
- <li> Binary trailer
- <li> Text list of mapped objects
-</ul>
-
-<p>The binary data is expressed in terms of "slots." These are words
-large enough to hold the program's pointer type, i.e., for 32-bit
-programs they are 4 bytes in size, and for 64-bit programs they are 8
-bytes. They are stored in the profile data file in the native byte
-order (i.e., little-endian for x86 and x86_64).
-
-
-<h2>Binary Header</h2>
-
-<p>The binary header format is show below. Values written by the
-profiler, along with requirements currently enforced by the analysis
-tools, are shown in parentheses.
-
-<p>
-<table summary="Header Format"
- frame="box" rules="sides" cellpadding="5" width="50%">
- <tr>
- <th width="30%">slot</th>
- <th width="70%">data</th>
- </tr>
-
- <tr>
- <td>0</td>
- <td>header count (0; must be 0)</td>
- </tr>
-
- <tr>
- <td>1</td>
- <td>header slots after this one (3; must be >= 3)</td>
- </tr>
-
- <tr>
- <td>2</td>
- <td>format version (0; must be 0)</td>
- </tr>
-
- <tr>
- <td>3</td>
- <td>sampling period, in microseconds</td>
- </tr>
-
- <tr>
- <td>4</td>
- <td>padding (0)</td>
- </tr>
-</table>
-
-<p>The headers currently generated for 32-bit and 64-bit little-endian
-(x86 and x86_64) profiles are shown below, for comparison.
-
-<p>
-<table summary="Header Example" frame="box" rules="sides" cellpadding="5">
- <tr>
- <th></th>
- <th>hdr count</th>
- <th>hdr words</th>
- <th>version</th>
- <th>sampling period</th>
- <th>pad</th>
- </tr>
- <tr>
- <td>32-bit or 64-bit (slots)</td>
- <td>0</td>
- <td>3</td>
- <td>0</td>
- <td>10000</td>
- <td>0</td>
- </tr>
- <tr>
- <td>32-bit (4-byte words in file)</td>
- <td><tt>0x00000</tt></td>
- <td><tt>0x00003</tt></td>
- <td><tt>0x00000</tt></td>
- <td><tt>0x02710</tt></td>
- <td><tt>0x00000</tt></td>
- </tr>
- <tr>
- <td>64-bit LE (4-byte words in file)</td>
- <td><tt>0x00000 0x00000</tt></td>
- <td><tt>0x00003 0x00000</tt></td>
- <td><tt>0x00000 0x00000</tt></td>
- <td><tt>0x02710 0x00000</tt></td>
- <td><tt>0x00000 0x00000</tt></td>
- </tr>
-</table>
-
-<p>The contents are shown in terms of slots, and in terms of 4-byte
-words in the profile data file. The slot contents for 32-bit and
-64-bit headers are identical. For 32-bit profiles, the 4-byte word
-view matches the slot view. For 64-bit profiles, each (8-byte) slot
-is shown as two 4-byte words, ordered as they would appear in the
-file.
-
-<p>The profiling tools examine the contents of the file and use the
-expected locations and values of the header words field to detect
-whether the file is 32-bit or 64-bit.
-
-
-<h2>Binary Profile Records</h2>
-
-<p>The binary profile record format is shown below.
-
-<p>
-<table summary="Profile Record Format"
- frame="box" rules="sides" cellpadding="5" width="50%">
- <tr>
- <th width="30%">slot</th>
- <th width="70%">data</th>
- </tr>
-
- <tr>
- <td>0</td>
- <td>sample count, must be >= 1</td>
- </tr>
-
- <tr>
- <td>1</td>
- <td>number of call chain PCs (num_pcs), must be >= 1</td>
- </tr>
-
- <tr>
- <td>2 .. (num_pcs + 1)</td>
- <td>call chain PCs, most-recently-called function first.
- </tr>
-</table>
-
-<p>The total length of a given record is 2 + num_pcs.
-
-<p>Note that multiple profile records can be emitted by the profiler
-having an identical call chain. In that case, analysis tools should
-sum the counts of all records having identical call chains.
-
-<p><b>Note:</b> Some profile analysis tools terminate if they see
-<em>any</em> profile record with a call chain with its first entry
-having the address 0. (This is similar to the binary trailer.)
-
-<h3>Example</h3>
-
-This example shows the slots contained in a sample profile record.
-
-<p>
-<table summary="Profile Record Example"
- frame="box" rules="sides" cellpadding="5">
- <tr>
- <td>5</td>
- <td>3</td>
- <td>0xa0000</td>
- <td>0xc0000</td>
- <td>0xe0000</td>
- </tr>
-</table>
-
-<p>In this example, 5 ticks were received at PC 0xa0000, whose
-function had been called by the function containing 0xc0000, which had
-been called from the function containing 0xe0000.
-
-
-<h2>Binary Trailer</h2>
-
-<p>The binary trailer consists of three slots of data with fixed
-values, shown below.
-
-<p>
-<table summary="Trailer Format"
- frame="box" rules="sides" cellpadding="5" width="50%">
- <tr>
- <th width="30%">slot</th>
- <th width="70%">value</th>
- </tr>
-
- <tr>
- <td>0</td>
- <td>0</td>
- </tr>
-
- <tr>
- <td>1</td>
- <td>1</td>
- </tr>
-
- <tr>
- <td>2</td>
- <td>0</td>
- </tr>
-</table>
-
-<p>Note that this is the same data that would contained in a profile
-record with sample count = 0, num_pcs = 1, and a one-element call
-chain containing the address 0.
-
-
-<h2>Text List of Mapped Objects</h2>
-
-<p>The binary data in the file is followed immediately by a list of
-mapped objects. This list consists of lines of text separated by
-newline characters.
-
-<p>Each line is one of the following types:
-
-<ul>
- <li>Build specifier, starting with "<tt>build=</tt>". For example:
- <pre> build=/path/to/binary</pre>
- Leading spaces on the line are ignored.
-
- <li>Mapping line from ProcMapsIterator::FormatLine. For example:
- <pre> 40000000-40015000 r-xp 00000000 03:01 12845071 /lib/ld-2.3.2.so</pre>
- The first address must start at the beginning of the line.
-</ul>
-
-<p>Unrecognized lines should be ignored by analysis tools.
-
-<p>When processing the paths see in mapping lines, occurrences of
-<tt>$build</tt> followed by a non-word character (i.e., characters
-other than underscore or alphanumeric characters), should be replaced
-by the path given on the last build specifier line.

-
-<p>This is the CPU profiler we use at Google. There are three parts
-to using it: linking the library into an application, running the
-code, and analyzing the output.</p>
-
-<p>On the off-chance that you should need to understand it, the CPU
-profiler data file format is documented separately,
-<a href="cpuprofile-fileformat.html">here</a>.
-
-
-<H1>Linking in the Library</H1>
-
-<p>To install the CPU profiler into your executable, add
-<code>-lprofiler</code> to the link-time step for your executable.
-(It's also probably possible to add in the profiler at run-time using
-<code>LD_PRELOAD</code>, e.g.
-<code>% env LD_PRELOAD="/usr/lib/libprofiler.so" <binary></code>,
-but this isn't necessarily recommended.)</p>
-
-<p>This does <i>not</i> turn on CPU profiling; it just inserts the
-code. For that reason, it's practical to just always link
-<code>-lprofiler</code> into a binary while developing; that's what we
-do at Google. (However, since any user can turn on the profiler by
-setting an environment variable, it's not necessarily recommended to
-install profiler-linked binaries into a production, running
-system.)</p>
-
-
-<H1>Running the Code</H1>
-
-<p>There are several alternatives to actually turn on CPU profiling
-for a given run of an executable:</p>
-
-<ol>
- <li> <p>Define the environment variable CPUPROFILE to the filename
- to dump the profile to. For instance, if you had a version of
- <code>/bin/ls</code> that had been linked against libprofiler,
- you could run:</p>
- <pre>% env CPUPROFILE=ls.prof /bin/ls</pre>
- </li>
- <li> <p>In addition to defining the environment variable CPUPROFILE
- you can also define CPUPROFILESIGNAL. This allows profiling to be
- controlled via the signal number that you specify. The signal number
- must be unused by the program under normal operation. Internally it
- acts as a switch, triggered by the signal, which is off by default.
- For instance, if you had a copy of <code>/bin/chrome</code> that had been
- been linked against libprofiler, you could run:</p>
- <pre>% env CPUPROFILE=chrome.prof CPUPROFILESIGNAL=12 /bin/chrome &</pre>
- <p>You can then trigger profiling to start:</p>
- <pre>% killall -12 chrome</pre>
- <p>Then after a period of time you can tell it to stop which will
- generate the profile:</p>
- <pre>% killall -12 chrome</pre>
- </li>
- <li> <p>In your code, bracket the code you want profiled in calls to
- <code>ProfilerStart()</code> and <code>ProfilerStop()</code>.
- (These functions are declared in <code><gperftools/profiler.h></code>.)
- <code>ProfilerStart()</code> will take
- the profile-filename as an argument.</p>
- </li>
-</ol>
-
-<p>In Linux 2.6 and above, profiling works correctly with threads,
-automatically profiling all threads. In Linux 2.4, profiling only
-profiles the main thread (due to a kernel bug involving itimers and

-<h1><a name="pprof">Analyzing the Output</a></h1>
-
-<p><code>pprof</code> is the script used to analyze a profile. It has
-many output modes, both textual and graphical. Some give just raw
-numbers, much like the <code>-pg</code> output of <code>gcc</code>,
-and others show the data in the form of a dependency graph.</p>
-
-<p>pprof <b>requires</b> <code>perl5</code> to be installed to run.
-It also requires <code>dot</code> to be installed for any of the
-graphical output routines, and <code>gv</code> to be installed for
-<code>--gv</code> mode (described below).
-</p>
-
-<p>Here are some ways to call pprof. These are described in more
-detail below.</p>
-
-<pre>
-% pprof /bin/ls ls.prof
- Enters "interactive" mode
-% pprof --text /bin/ls ls.prof
- Outputs one line per procedure
-% pprof --gv /bin/ls ls.prof
- Displays annotated call-graph via 'gv'
-% pprof --gv --focus=Mutex /bin/ls ls.prof
- Restricts to code paths including a .*Mutex.* entry
-% pprof --gv --focus=Mutex --ignore=string /bin/ls ls.prof
- Code paths including Mutex but not string
-% pprof --list=getdir /bin/ls ls.prof
- (Per-line) annotated source listing for getdir()
-% pprof --disasm=getdir /bin/ls ls.prof
- (Per-PC) annotated disassembly for getdir()
-% pprof --text localhost:1234
- Outputs one line per procedure for localhost:1234
-% pprof --callgrind /bin/ls ls.prof
- Outputs the call information in callgrind format
-</pre>
-
-
-<h3>Analyzing Text Output</h3>
-
-<p>Text mode has lines of output that look like this:</p>
-<pre>
- 14 2.1% 17.2% 58 8.7% std::_Rb_tree::find
-</pre>
-
-<p>Here is how to interpret the columns:</p>
-<ol>
- <li> Number of profiling samples in this function
- <li> Percentage of profiling samples in this function
- <li> Percentage of profiling samples in the functions printed so far
- <li> Number of profiling samples in this function and its callees
- <li> Percentage of profiling samples in this function and its callees
- <li> Function name
-</ol>
-
-<h3>Analyzing Callgrind Output</h3>
-
-<p>Use <a href="http://kcachegrind.sourceforge.net">kcachegrind</a> to
-analyze your callgrind output:</p>
-<pre>
-% pprof --callgrind /bin/ls ls.prof > ls.callgrind
-% kcachegrind ls.callgrind
-</pre>
-
-<p>The cost is specified in 'hits', i.e. how many times a function
-appears in the recorded call stack information. The 'calls' from
-function a to b record how many times function b was found in the
-stack traces directly below function a.</p>
-
-<p>Tip: if you use a debug build the output will include file and line
-number information and kcachegrind will show an annotated source
-code view.</p>
-
-<h3>Node Information</h3>
-
-<p>In the various graphical modes of pprof, the output is a call graph
-annotated with timing information, like so:</p>
-
-<A HREF="pprof-test-big.gif">
-<center><table><tr><td>
- <img src="pprof-test.gif">
-</td></tr></table></center>
-</A>
-
-<p>Each node represents a procedure. The directed edges indicate
-caller to callee relations. Each node is formatted as follows:</p>
-
-<center><pre>
-Class Name
-Method Name
-local (percentage)
-<b>of</b> cumulative (percentage)
-</pre></center>
-
-<p>The last one or two lines contains the timing information. (The
-profiling is done via a sampling method, where by default we take 100
-samples a second. Therefor one unit of time in the output corresponds
-to about 10 milliseconds of execution time.) The "local" time is the
-time spent executing the instructions directly contained in the
-procedure (and in any other procedures that were inlined into the
-procedure). The "cumulative" time is the sum of the "local" time and
-the time spent in any callees. If the cumulative time is the same as
-the local time, it is not printed.</p>
-
-<p>For instance, the timing information for test_main_thread()
-indicates that 155 units (about 1.55 seconds) were spent executing the
-code in <code>test_main_thread()</code> and 200 units were spent while
-executing <code>test_main_thread()</code> and its callees such as
-<code>snprintf()</code>.</p>
-
-<p>The size of the node is proportional to the local count. The
-percentage displayed in the node corresponds to the count divided by
-the total run time of the program (that is, the cumulative count for
-<code>main()</code>).</p>
-
-<h3>Edge Information</h3>
-
-<p>An edge from one node to another indicates a caller to callee
-relationship. Each edge is labelled with the time spent by the callee
-on behalf of the caller. E.g, the edge from
-<code>test_main_thread()</code> to <code>snprintf()</code> indicates
-that of the 200 samples in <code>test_main_thread()</code>, 37 are
-because of calls to <code>snprintf()</code>.</p>
-
-<p>Note that <code>test_main_thread()</code> has an edge to
-<code>vsnprintf()</code>, even though <code>test_main_thread()</code>
-doesn't call that function directly. This is because the code was
-compiled with <code>-O2</code>; the profile reflects the optimized
-control flow.</p>
-
-<h3>Meta Information</h3>
-
-<p>The top of the display should contain some meta information
-like:</p>
-<pre>
- /tmp/profiler2_unittest
- Total samples: 202
- Focusing on: 202
- Dropped nodes with <= 1 abs(samples)
- Dropped edges with <= 0 samples
-</pre>
-
-<p>This section contains the name of the program, and the total
-samples collected during the profiling run. If the
-<code>--focus</code> option is on (see the <a href="#focus">Focus</a>
-section below), the legend also contains the number of samples being
-shown in the focused display. Furthermore, some unimportant nodes and
-edges are dropped to reduce clutter. The characteristics of the
-dropped nodes and edges are also displayed in the legend.</p>
-
-<h3><a name=focus>Focus and Ignore</a></h3>
-
-<p>You can ask pprof to generate a display focused on a particular
-piece of the program. You specify a regular expression. Any portion
-of the call-graph that is on a path which contains at least one node
-matching the regular expression is preserved. The rest of the
-call-graph is dropped on the floor. For example, you can focus on the
-<code>vsnprintf()</code> libc call in <code>profiler2_unittest</code>
-as follows:</p>
-
-<pre>
-% pprof --gv --focus=vsnprintf /tmp/profiler2_unittest test.prof
-</pre>
-<A HREF="pprof-vsnprintf-big.gif">
-<center><table><tr><td>
- <img src="pprof-vsnprintf.gif">
-</td></tr></table></center>
-</A>
-
-<p>Similarly, you can supply the <code>--ignore</code> option to
-ignore samples that match a specified regular expression. E.g., if
-you are interested in everything except calls to
-<code>snprintf()</code>, you can say:</p>
-<pre>
-% pprof --gv --ignore=snprintf /tmp/profiler2_unittest test.prof
-</pre>
-
-
-<h3>Interactive mode</a></h3>
-
-<p>By default -- if you don't specify any flags to the contrary --
-pprof runs in interactive mode. At the <code>(pprof)</code> prompt,
-you can run many of the commands described above. You can type
-<code>help</code> for a list of what commands are available in
-interactive mode.</p>
-
-<h3><a name=options>pprof Options</a></h3>
-
-For a complete list of pprof options, you can run <code>pprof
---help</code>.
-
-<h4>Output Type</h4>
-
-<p>
-<center>
-<table frame=box rules=sides cellpadding=5 width=100%>
-<tr valign=top>
- <td><code>--text</code></td>
- <td>
- Produces a textual listing. (Note: If you have an X display, and
- <code>dot</code> and <code>gv</code> installed, you will probably
- be happier with the <code>--gv</code> output.)
- </td>
-</tr>
-<tr valign=top>
- <td><code>--gv</code></td>
- <td>
- Generates annotated call-graph, converts to postscript, and
- displays via gv (requres <code>dot</code> and <code>gv</code> be
- installed).
- </td>
-</tr>
-<tr valign=top>
- <td><code>--dot</code></td>
- <td>
- Generates the annotated call-graph in dot format and
- emits to stdout (requres <code>dot</code> be installed).
- </td>
-</tr>
-<tr valign=top>
- <td><code>--ps</code></td>
- <td>
- Generates the annotated call-graph in Postscript format and
- emits to stdout (requres <code>dot</code> be installed).
- </td>
-</tr>
-<tr valign=top>
- <td><code>--pdf</code></td>
- <td>
- Generates the annotated call-graph in PDF format and emits to
- stdout (requires <code>dot</code> and <code>ps2pdf</code> be
- installed).
- </td>
-</tr>
-<tr valign=top>
- <td><code>--gif</code></td>
- <td>
- Generates the annotated call-graph in GIF format and
- emits to stdout (requres <code>dot</code> be installed).
- </td>
-</tr>
-<tr valign=top>
- <td><code>--list=<<i>regexp</i>></code></td>
- <td>
- <p>Outputs source-code listing of routines whose
- name matches <regexp>. Each line
- in the listing is annotated with flat and cumulative
- sample counts.</p>
-
- <p>In the presence of inlined calls, the samples
- associated with inlined code tend to get assigned
- to a line that follows the location of the
- inlined call. A more precise accounting can be
- obtained by disassembling the routine using the
- --disasm flag.</p>
- </td>
-</tr>
-<tr valign=top>
- <td><code>--disasm=<<i>regexp</i>></code></td>
- <td>
- Generates disassembly of routines that match
- <regexp>, annotated with flat and
- cumulative sample counts and emits to stdout.
- </td>
-</tr>
-</table>
-</center>
-
-<h4>Reporting Granularity</h4>
-
-<p>By default, pprof produces one entry per procedure. However you can
-use one of the following options to change the granularity of the
-output. The <code>--files</code> option seems to be particularly
-useless, and may be removed eventually.</p>
-
-<center>
-<table frame=box rules=sides cellpadding=5 width=100%>
-<tr valign=top>
- <td><code>--addresses</code></td>
- <td>
- Produce one node per program address.
- </td>
-</tr>
- <td><code>--lines</code></td>
- <td>
- Produce one node per source line.
- </td>
-</tr>
- <td><code>--functions</code></td>
- <td>
- Produce one node per function (this is the default).
- </td>
-</tr>
- <td><code>--files</code></td>
- <td>
- Produce one node per source file.
- </td>
-</tr>
-</table>
-</center>
-
-<h4>Controlling the Call Graph Display</h4>
-
-<p>Some nodes and edges are dropped to reduce clutter in the output
-display. The following options control this effect:</p>
-
-<center>
-<table frame=box rules=sides cellpadding=5 width=100%>
-<tr valign=top>
- <td><code>--nodecount=<n></code></td>
- <td>
- This option controls the number of displayed nodes. The nodes
- are first sorted by decreasing cumulative count, and then only
- the top N nodes are kept. The default value is 80.
- </td>
-</tr>
-<tr valign=top>
- <td><code>--nodefraction=<f></code></td>
- <td>
- This option provides another mechanism for discarding nodes
- from the display. If the cumulative count for a node is
- less than this option's value multiplied by the total count
- for the profile, the node is dropped. The default value
- is 0.005; i.e. nodes that account for less than
- half a percent of the total time are dropped. A node
- is dropped if either this condition is satisfied, or the
- --nodecount condition is satisfied.
- </td>
-</tr>
-<tr valign=top>
- <td><code>--edgefraction=<f></code></td>
- <td>
- This option controls the number of displayed edges. First of all,
- an edge is dropped if either its source or destination node is
- dropped. Otherwise, the edge is dropped if the sample
- count along the edge is less than this option's value multiplied
- by the total count for the profile. The default value is
- 0.001; i.e., edges that account for less than
- 0.1% of the total time are dropped.
- </td>
-</tr>
-<tr valign=top>
- <td><code>--focus=<re></code></td>
- <td>
- This option controls what region of the graph is displayed
- based on the regular expression supplied with the option.
- For any path in the callgraph, we check all nodes in the path
- against the supplied regular expression. If none of the nodes
- match, the path is dropped from the output.
- </td>
-</tr>
-<tr valign=top>
- <td><code>--ignore=<re></code></td>
- <td>
- This option controls what region of the graph is displayed
- based on the regular expression supplied with the option.
- For any path in the callgraph, we check all nodes in the path
- against the supplied regular expression. If any of the nodes
- match, the path is dropped from the output.
- </td>
-</tr>
-</table>
-</center>
-
-<p>The dropped edges and nodes account for some count mismatches in
-the display. For example, the cumulative count for
-<code>snprintf()</code> in the first diagram above was 41. However
-the local count (1) and the count along the outgoing edges (12+1+20+6)
-add up to only 40.</p>
-
-
-<h1>Caveats</h1>
-
-<ul>
- <li> If the program exits because of a signal, the generated profile
- will be <font color=red>incomplete, and may perhaps be
- completely empty</font>.
- <li> The displayed graph may have disconnected regions because
- of the edge-dropping heuristics described above.
- <li> If the program linked in a library that was not compiled
- with enough symbolic information, all samples associated
- with the library may be charged to the last symbol found
- in the program before the library. This will artificially
- inflate the count for that symbol.
- <li> If you run the program on one machine, and profile it on
- another, and the shared libraries are different on the two
- machines, the profiling output may be confusing: samples that
- fall within shared libaries may be assigned to arbitrary
- procedures.
- <li> If your program forks, the children will also be profiled
- (since they inherit the same CPUPROFILE setting). Each process
- is profiled separately; to distinguish the child profiles from
- the parent profile and from each other, all children will have
- their process-id appended to the CPUPROFILE name.
- <li> Due to a hack we make to work around a possible gcc bug, your
- profiles may end up named strangely if the first character of
- your CPUPROFILE variable has ascii value greater than 127.
- This should be exceedingly rare, but if you need to use such a
- name, just set prepend <code>./</code> to your filename:
- <code>CPUPROFILE=./Ägypten</code>.
-</ul>

-/* This file defines dynamic annotations for use with dynamic analysis
- tool such as valgrind, PIN, etc.
-
- Dynamic annotation is a source code annotation that affects
- the generated code (that is, the annotation is not a comment).
- Each such annotation is attached to a particular
- instruction and/or to a particular object (address) in the program.
-
- The annotations that should be used by users are macros in all upper-case
- (e.g., ANNOTATE_NEW_MEMORY).
-
- Actual implementation of these macros may differ depending on the
- dynamic analysis tool being used.
-
- See http://code.google.com/p/data-race-test/ for more information.
-
- This file supports the following dynamic analysis tools:
- - None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
- Macros are defined empty.
- - ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
- Macros are defined as calls to non-inlinable empty functions
- that are intercepted by Valgrind. */

- Annotations useful when implementing condition variables such as CondVar,
- using conditional critical sections (Await/LockWhen) and when constructing
- user-defined synchronization mechanisms.
-
- The annotations ANNOTATE_HAPPENS_BEFORE() and ANNOTATE_HAPPENS_AFTER() can
- be used to define happens-before arcs in user-defined synchronization
- mechanisms: the race detector will infer an arc from the former to the
- latter when they share the same argument pointer.
-
- Example 1 (reference counting):
-
- void Unref() {
- ANNOTATE_HAPPENS_BEFORE(&refcount_);
- if (AtomicDecrementByOne(&refcount_) == 0) {
- ANNOTATE_HAPPENS_AFTER(&refcount_);
- delete this;

- Example 2 (message queue):
-
- void MyQueue::Put(Type *e) {
- MutexLock lock(&mu_);
- ANNOTATE_HAPPENS_BEFORE(e);
- PutElementIntoMyQueue(e);
- }
-
- Type *MyQueue::Get() {
- MutexLock lock(&mu_);
- Type *e = GetElementFromMyQueue();
- ANNOTATE_HAPPENS_AFTER(e);
- return e;
- }
-
- Note: when possible, please use the existing reference counting and message

-//
-// void MyFunc() {
-// if (FLAGS_verbose) printf("Records %d-%d\n", FLAGS_start, FLAGS_end);

-// --- A note about thread-safety:
-//
-// We describe many functions in this routine as being thread-hostile,

-//
-// thread-safe: it is safe for multiple threads to call this routine
-// (or, when referring to a class, methods of this class)
-// concurrently.
-// thread-hostile: it is not safe for multiple threads to call this
-// routine (or methods of this class) concurrently. In gflags,
-// most thread-hostile routines are intended to be called early in,
-// or even before, main() -- that is, before threads are spawned.
-// thread-compatible: it is safe for multiple threads to read from
-// this variable (when applied to variables), or to call const
-// methods of this class (when applied to classes), as long as no
-// other thread is writing to the variable or calling non-const
-// methods of this class.

-// Now come the command line flag declaration/definition macros that

-// variables in global constructors and have that not crash, even if
-// their global constructor runs before the global constructor here.
-// (Obviously, we can't guarantee the flags will have the correct
-// default value in that case, but at least accessing them is safe.)
-// The only way to do that is have flags point to a static buffer.
-// So we make one, using a union to ensure proper alignment, and
-// then use placement-new to actually set up the flag with the
-// correct default value. In the same vein, we have to worry about
-// flag access in global destructors, so FlagRegisterer has to be
-// careful never to destroy the flag-values it constructs.
-//
-// Note that when we define a flag variable FLAGS_<name>, we also
-// preemptively define a junk variable, FLAGS_no<name>. This is to
-// cause a link-time error if someone tries to define 2 flags with
-// names like "logging" and "nologging". We do this because a bool
-// flag FLAG can be set from the command line to true with a "-FLAG"
-// argument, and to false with a "-noFLAG" argument, and so this can
-// potentially avert confusion.
-//
-// We also put flags into their own namespace. It is purposefully
-// named in an opaque way that people should have trouble typing
-// directly. The idea is that DEFINE puts the flag in the weird
-// namespace, and DECLARE imports the flag from there into the current
-// namespace. The net result is to force people to use DECLARE to get
-// access to a flag, rather than saying "extern GFLAGS_DLL_DECL bool FLAGS_whatever;"
-// or some such instead. We want this so we can put extra
-// functionality (like sanity-checking) in DECLARE if we want, and
-// make sure it is picked up everywhere.

-// Bash-style command line flag completion for C++ binaries
-//
-// This module implements bash-style completions. It achieves this
-// goal in the following broad chunks:
-//
-// 1) Take a to-be-completed word, and examine it for search hints
-// 2) Identify all potentially matching flags
-// 2a) If there are no matching flags, do nothing.
-// 2b) If all matching flags share a common prefix longer than the
-// completion word, output just that matching prefix
-// 3) Categorize those flags to produce a rough ordering of relevence.
-// 4) Potentially trim the set of flags returned to a smaller number
-// that bash is happier with
-// 5) Output the matching flags in groups ordered by relevence.
-// 5a) Force bash to place most-relevent groups at the top of the list
-// 5b) Trim most flag's descriptions to fit on a single terminal line

-//
-// Implement helpful bash-style command line flag completions
-//
-// ** Functional API:
-// HandleCommandLineCompletions() should be called early during
-// program startup, but after command line flag code has been
-// initialized, such as the beginning of HandleCommandLineHelpFlags().
-// It checks the value of the flag --tab_completion_word. If this
-// flag is empty, nothing happens here. If it contains a string,
-// however, then HandleCommandLineCompletions() will hijack the
-// process, attempting to identify the intention behind this
-// completion. Regardless of the outcome of this deduction, the
-// process will be terminated, similar to --helpshort flag
-// handling.
-//
-// ** Overview of Bash completions:
-// Bash can be told to programatically determine completions for the
-// current 'cursor word'. It does this by (in this case) invoking a
-// command with some additional arguments identifying the command
-// being executed, the word being completed, and the previous word
-// (if any). Bash then expects a sequence of output lines to be
-// printed to stdout. If these lines all contain a common prefix
-// longer than the cursor word, bash will replace the cursor word
-// with that common prefix, and display nothing. If there isn't such
-// a common prefix, bash will display the lines in pages using 'more'.
-//
-// ** Strategy taken for command line completions:
-// If we can deduce either the exact flag intended, or a common flag
-// prefix, we'll output exactly that. Otherwise, if information
-// must be displayed to the user, we'll take the opportunity to add
-// some helpful information beyond just the flag name (specifically,
-// we'll include the default flag value and as much of the flag's
-// description as can fit on a single terminal line width, as specified
-// by the flag --tab_completion_columns). Furthermore, we'll try to
-// make bash order the output such that the most useful or relevent
-// flags are the most likely to be shown at the top.
-//
-// ** Additional features:
-// To assist in finding that one really useful flag, substring matching
-// was implemented. Before pressing a <TAB> to get completion for the
-// current word, you can append one or more '?' to the flag to do
-// substring matching. Here's the semantics:
-// --foo<TAB> Show me all flags with names prefixed by 'foo'
-// --foo?<TAB> Show me all flags with 'foo' somewhere in the name
-// --foo??<TAB> Same as prior case, but also search in module
-// definition path for 'foo'
-// --foo???<TAB> Same as prior case, but also search in flag
-// descriptions for 'foo'
-// Finally, we'll trim the output to a relatively small number of
-// flags to keep bash quiet about the verbosity of output. If one
-// really wanted to see all possible matches, appending a '+' to the
-// search word will force the exhaustive list of matches to be printed.
-//
-// ** How to have bash accept completions from a binary:
-// Bash requires that it be informed about each command that programmatic
-// completion should be enabled for. Example addition to a .bashrc
-// file would be (your path to gflags_completions.sh file may differ):
-
-/*
-$ complete -o bashdefault -o default -o nospace -C \
- '/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \
- time env binary_name another_binary [...]
-*/
-
-// This would allow the following to work:
-// $ /path/to/binary_name --vmodule<TAB>
-// Or:
-// $ ./bin/path/another_binary --gfs_u<TAB>
-// (etc)
-//
-// Sadly, it appears that bash gives no easy way to force this behavior for
-// all commands. That's where the "time" in the above example comes in.
-// If you haven't specifically added a command to the list of completion
-// supported commands, you can still get completions by prefixing the
-// entire command with "env".
-// $ env /some/brand/new/binary --vmod<TAB>
-// Assuming that "binary" is a newly compiled binary, this should still
-// produce the expected completion output.

-# This script is invoked by bash in response to a matching compspec. When
-# this happens, bash calls this script using the command shown in the -C
-# block of the complete entry, but also appends 3 arguments. They are:
-# - The command being used for completion
-# - The word being completed
-# - The word preceding the completion word.
-#
-# Here's an example of how you might use this script:
-# $ complete -o bashdefault -o default -o nospace -C \
-# '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \
-# time env binary_name another_binary [...]
-
-# completion_word_index gets the index of the (N-1)th argument for
-# this command line. completion_word gets the actual argument from
-# this command line at the (N-1)th position
-completion_word_index="$(($# - 1))"
-completion_word="${!completion_word_index}"
-
-# TODO(user): Replace this once gflags_completions.cc has
-# a bool parameter indicating unambiguously to hijack the process for
-# completion purposes.
-if [ -z "$completion_word" ]; then
- # Until an empty value for the completion word stops being misunderstood
- # by binaries, don't actually execute the binary or the process
- # won't be hijacked!
- exit 0
-fi
-
-# binary_index gets the index of the command being completed (which bash
-# places in the (N-2)nd position. binary gets the actual command from
-# this command line at that (N-2)nd position
-binary_index="$(($# - 2))"
-binary="${!binary_index}"
-
-# For completions to be universal, we may have setup the compspec to
-# trigger on 'harmless pass-through' commands, like 'time' or 'env'.
-# If the command being completed is one of those two, we'll need to
-# identify the actual command being executed. To do this, we need
-# the actual command line that the <TAB> was pressed on. Bash helpfully
-# places this in the $COMP_LINE variable.
-if [ "$binary" == "time" ] || [ "$binary" == "env" ]; then
- # we'll assume that the first 'argument' is actually the
- # binary
-
-
- # TODO(user): This is not perfect - the 'env' command, for instance,
- # is allowed to have options between the 'env' and 'the command to
- # be executed'. For example, consider:
- # $ env FOO="bar" bin/do_something --help<TAB>
- # In this case, we'll mistake the FOO="bar" portion as the binary.
- # Perhaps we should continuing consuming leading words until we
- # either run out of words, or find a word that is a valid file
- # marked as executable. I can't think of any reason this wouldn't
- # work.
-
- # Break up the 'original command line' (not this script's command line,
- # rather the one the <TAB> was pressed on) and find the second word.
- parts=( ${COMP_LINE} )

-

-// work that may be required for this OS. (Note we cannot entirely
-// control when tcmalloc is initialized, and the system may do some
-// mallocs and frees before this routine is called.) It may be a
-// noop.
-//
-// Every libc has its own way of doing this, and sometimes the compiler

-dnl
-dnl @summary figure out how to build C programs using POSIX threads
-dnl
-dnl This macro figures out how to build C programs using POSIX threads.
-dnl It sets the PTHREAD_LIBS output variable to the threads library and
-dnl linker flags, and the PTHREAD_CFLAGS output variable to any special
-dnl C compiler flags that are needed. (The user can also force certain
-dnl compiler flags/libs to be tested by setting these environment
-dnl variables.)
-dnl
-dnl Also sets PTHREAD_CC to any special C compiler that is needed for
-dnl multi-threaded programs (defaults to the value of CC otherwise).
-dnl (This is necessary on AIX to use the special cc_r compiler alias.)
-dnl
-dnl NOTE: You are assumed to not only compile your program with these
-dnl flags, but also link it with them as well. e.g. you should link
-dnl with $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS
-dnl $LIBS
-dnl
-dnl If you are only building threads programs, you may wish to use
-dnl these variables in your default LIBS, CFLAGS, and CC:
-dnl
-dnl LIBS="$PTHREAD_LIBS $LIBS"
-dnl CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
-dnl CC="$PTHREAD_CC"
-dnl
-dnl In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute
-dnl constant has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to
-dnl that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
-dnl
-dnl ACTION-IF-FOUND is a list of shell commands to run if a threads
-dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands to
-dnl run it if it is not found. If ACTION-IF-FOUND is not specified, the
-dnl default action will define HAVE_PTHREAD.
-dnl
-dnl Please let the authors know if this macro fails on any platform, or
-dnl if you have any other suggestions or comments. This macro was based
-dnl on work by SGJ on autoconf scripts for FFTW (www.fftw.org) (with
-dnl help from M. Frigo), as well as ac_pthread and hb_pthread macros
-dnl posted by Alejandro Forero Cuervo to the autoconf macro repository.
-dnl We are also grateful for the helpful feedback of numerous users.

-// Sampler to decide when to create a sample trace for an allocation
-// Not thread safe: Each thread should have it's own sampler object.
-// Caller must use external synchronization if used
-// from multiple threads.
-//
-// With 512K average sample step (the default):
-// the probability of sampling a 4K allocation is about 0.00778
-// the probability of sampling a 1MB allocation is about 0.865
-// the probability of sampling a 1GB allocation is about 1.00000
-// In general, the probablity of sampling is an allocation of size X
-// given a flag value of Y (default 1M) is:
-// 1 - e^(-X/Y)
-//
-// With 128K average sample step:
-// the probability of sampling a 1MB allocation is about 0.99966
-// the probability of sampling a 1GB allocation is about 1.0
-// (about 1 - 2**(-26))
-// With 1M average sample step:
-// the probability of sampling a 4K allocation is about 0.00390
-// the probability of sampling a 1MB allocation is about 0.632
-// the probability of sampling a 1GB allocation is about 1.0
-//
-// The sampler works by representing memory as a long stream from
-// which allocations are taken. Some of the bytes in this stream are
-// marked and if an allocation includes a marked byte then it is
-// sampled. Bytes are marked according to a Poisson point process
-// with each byte being marked independently with probability
-// p = 1/tcmalloc_sample_parameter. This makes the probability
-// of sampling an allocation of X bytes equal to the CDF of
-// a geometric with mean tcmalloc_sample_parameter. (ie. the
-// probability that at least one byte in the range is marked). This
-// is accurately given by the CDF of the corresponding exponential
-// distribution : 1 - e^(X/tcmalloc_sample_parameter_)
-// Independence of the byte marking ensures independence of
-// the sampling of each allocation.
-//
-// This scheme is implemented by noting that, starting from any
-// fixed place, the number of bytes until the next marked byte
-// is geometrically distributed. This number is recorded as
-// bytes_until_sample_. Every allocation subtracts from this
-// number until it is less than 0. When this happens the current
-// allocation is sampled.
-//
-// When an allocation occurs, bytes_until_sample_ is reset to
-// a new independtly sampled geometric number of bytes. The
-// memoryless property of the point process means that this may
-// be taken as the number of bytes after the end of the current
-// allocation until the next marked byte. This ensures that
-// very large allocations which would intersect many marked bytes
-// only result in a single call to PickNextSamplingPoint.

- <profile> is a remote form. Symbols are obtained from host:port$SYMBOL_PAGE
-
- Each name can be:
- /path/to/profile - a path to a profile file
- host:port[/<service>] - a location of a service to get profile from
-
- The /<service> can be $HEAP_PAGE, $PROFILE_PAGE, /pprof/pmuprofile,
- $GROWTH_PAGE, $CONTENTION_PAGE, /pprof/wall,
- $CENSUSPROFILE_PAGE, or /pprof/filteredprofile.
- For instance:
- pprof http://myserver.com:80$HEAP_PAGE
- If /<service> is omitted, the service defaults to $PROFILE_PAGE (cpu profiling).
-pprof --symbols <program>
- Maps addresses to symbol names. In this mode, stdin should be a
- list of library mappings, in the same format as is found in the heap-
- and cpu-profile files (this loosely matches that of /proc/self/maps
- on linux), followed by a list of hex addresses to map, one per line.
-
- For more help with querying remote servers, including how to add the
- necessary server-side support code, see this filename (or one like it):
-
- /usr/doc/gperftools-$PPROF_VERSION/pprof_remote_servers.html
-
-Options:
- --cum Sort by cumulative data
- --base=<base> Subtract <base> from <profile> before display
- --interactive Run in interactive mode (interactive "help" gives help) [default]
- --seconds=<n> Length of time for dynamic profiles [default=30 secs]
- --add_lib=<file> Read additional symbols and line info from the given library
- --lib_prefix=<dir> Comma separated list of library path prefixes
- --no_strip_temp Do not strip template arguments from function names
-
-Reporting Granularity:
- --addresses Report at address level
- --lines Report at source line level
- --functions Report at function level [default]
- --files Report at source file level
-
-Output type:
- --text Generate text report
- --stacks Generate stack traces similar to the heap profiler (requires --text)
- --callgrind Generate callgrind format to stdout
- --gv Generate Postscript and display
- --evince Generate PDF and display
- --web Generate SVG and display
- --list=<regexp> Generate source listing of matching routines
- --disasm=<regexp> Generate disassembly of matching routines
- --symbols Print demangled symbol names found at given addresses
- --dot Generate DOT file to stdout
- --ps Generate Postcript to stdout
- --pdf Generate PDF to stdout
- --svg Generate SVG to stdout
- --gif Generate GIF to stdout
- --raw Generate symbolized pprof data (useful with remote fetch)
-
-Heap-Profile Options:
- --inuse_space Display in-use (mega)bytes [default]
- --inuse_objects Display in-use objects
- --alloc_space Display allocated (mega)bytes
- --alloc_objects Display allocated objects
- --show_bytes Display space in bytes
- --drop_negative Ignore negative differences
-
-Contention-profile options:
- --total_delay Display total delay at each region [default]
- --contentions Display number of delays at each region
- --mean_delay Display mean delay at each region
-
-Call-graph Options:
- --nodecount=<n> Show at most so many nodes [default=80]
- --nodefraction=<f> Hide nodes below <f>*total [default=.005]
- --edgefraction=<f> Hide edges below <f>*total [default=.001]
- --maxdegree=<n> Max incoming/outgoing edges per node [default=8]
- --focus=<regexp> Focus on nodes matching <regexp>
- --ignore=<regexp> Ignore nodes matching <regexp>
- --scale=<n> Set GV scaling [default=0]
- --heapcheck Make nodes with non-0 object counts
- (i.e. direct leak generators) more visible
-
-Miscellaneous:
- --no-auto-signal-frm Automatically drop 2nd frame that is always same (cpu-only)
- (assuming that it is artifact of bad stack captures
- which include signal handler frames)
- --show_addresses Always show addresses when applicable
- --tools=<prefix or binary:fullpath>[,...] \$PATH for object tool pathnames
- --test Run unit tests
- --help This message
- --version Version information
-
-Environment Variables:
- PPROF_TMPDIR Profiles directory. Defaults to \$HOME/pprof
- PPROF_TOOLS Prefix for object tools pathnames
-
-Examples:
-
-pprof /bin/ls ls.prof
- Enters "interactive" mode
-pprof --text /bin/ls ls.prof
- Outputs one line per procedure
-pprof --web /bin/ls ls.prof
- Displays annotated call-graph in web browser
-pprof --gv /bin/ls ls.prof
- Displays annotated call-graph via 'gv'
-pprof --gv --focus=Mutex /bin/ls ls.prof
- Restricts to code paths including a .*Mutex.* entry
-pprof --gv --focus=Mutex --ignore=string /bin/ls ls.prof
- Code paths including Mutex but not string
-pprof --list=getdir /bin/ls ls.prof
- (Per-line) annotated source listing for getdir()
-pprof --disasm=getdir /bin/ls ls.prof
- (Per-PC) annotated disassembly for getdir()
-
-pprof http://localhost:1234/
- Enters "interactive" mode
-pprof --text localhost:1234
- Outputs one line per procedure for localhost:1234
-pprof --raw localhost:1234 > ./local.raw
-pprof --text ./local.raw
- Fetches a remote profile for later analysis and then
- analyzes it in text mode.

-Commands:
- gv
- gv [focus] [-ignore1] [-ignore2]
- Show graphical hierarchical display of current profile. Without
- any arguments, shows all samples in the profile. With the optional
- "focus" argument, restricts the samples shown to just those where
- the "focus" regular expression matches a routine name on the stack
- trace.
-
- web
- web [focus] [-ignore1] [-ignore2]
- Like GV, but displays profile in your web browser instead of using
- Ghostview. Works best if your web browser is already running.
- To change the browser that gets used:
- On Linux, set the /etc/alternatives/gnome-www-browser symlink.
- On OS X, change the Finder association for SVG files.
-
- list [routine_regexp] [-ignore1] [-ignore2]
- Show source listing of routines whose names match "routine_regexp"
-
- weblist [routine_regexp] [-ignore1] [-ignore2]
- Displays a source listing of routines whose names match "routine_regexp"
- in a web browser. You can click on source lines to view the
- corresponding disassembly.
-
- top [--cum] [-ignore1] [-ignore2]
- top20 [--cum] [-ignore1] [-ignore2]
- top37 [--cum] [-ignore1] [-ignore2]
- Show top lines ordered by flat profile count, or cumulative count
- if --cum is specified. If a number is present after 'top', the
- top K routines will be shown (defaults to showing the top 10)
-
- disasm [routine_regexp] [-ignore1] [-ignore2]
- Show disassembly of routines whose names match "routine_regexp",
- annotated with sample counts.
-
- callgrind
- callgrind [filename]
- Generates callgrind file. If no filename is given, kcachegrind is called.
-
- help - This listing
- quit or ^D - End pprof
-
-For commands that accept optional -ignore tags, samples where any routine in
-the stack trace matches the regular expression in any of the -ignore
-parameters will be ignored.
-
-Further pprof details are available at this location (or one similar):

-/**
- * SVGPan library 1.2
- * ====================
- *
- * Given an unique existing element with id "viewport", including the
- * the library into any SVG adds the following capabilities:
- *
- * - Mouse panning
- * - Mouse zooming (using the wheel)
- * - Object dargging
- *
- * Known issues:
- *
- * - Zooming (while panning) on Safari has still some issues
- *
- * Releases:
- *
- * 1.2, Sat Mar 20 08:42:50 GMT 2010, Zeng Xiaohui
- * Fixed a bug with browser mouse handler interaction
- *
- * 1.1, Wed Feb 3 17:39:33 GMT 2010, Zeng Xiaohui
- * Updated the zoom code to support the mouse wheel on Safari/Chrome
- *
- * 1.0, Andrea Leofreddi
- * First release

-// A malloc that uses a per-thread cache to satisfy small malloc requests.
-// (The time for malloc/free of a small object drops from 300 ns to 50 ns.)
-//
-// See doc/tcmalloc.html for a high-level
-// description of how this malloc works.
-//
-// SYNCHRONIZATION
-// 1. The thread-specific lists are accessed without acquiring any locks.
-// This is safe because each such list is only accessed by one thread.
-// 2. We have a lock per central free-list, and hold it while manipulating
-// the central free list for a particular size.
-// 3. The central page allocator is protected by "pageheap_lock".
-// 4. The pagemap (which maps from page-number to descriptor),
-// can be read without holding any locks, and written while holding
-// the "pageheap_lock".
-// 5. To improve performance, a subset of the information one can get
-// from the pagemap is cached in a data structure, pagemap_cache_,
-// that atomically reads and writes its entries. This cache can be
-// read and written without locking.
-//
-// This multi-threaded access to the pagemap is safe for fairly
-// subtle reasons. We basically assume that when an object X is
-// allocated by thread A and deallocated by thread B, there must
-// have been appropriate synchronization in the handoff of object
-// X from thread A to thread B. The same logic applies to pagemap_cache_.
-//
-// THE PAGEID-TO-SIZECLASS CACHE
-// Hot PageID-to-sizeclass mappings are held by pagemap_cache_. If this cache
-// returns 0 for a particular PageID then that means "no information," not that
-// the sizeclass is 0. The cache may have stale information for pages that do
-// not hold the beginning of any free()'able object. Staleness is eliminated
-// in Populate() for pages with sizeclass > 0 objects, and in do_malloc() and
-// do_memalign() for all other relevant pages.
-//
-// PAGEMAP
-// -------
-// Page map contains a mapping from page id to Span.
-//
-// If Span s occupies pages [p..q],
-// pagemap[p] == s
-// pagemap[q] == s
-// pagemap[p+1..q-1] are undefined
-// pagemap[p-1] and pagemap[q+1] are defined:
-// NULL if the corresponding page is not yet in the address space.
-// Otherwise it points to a Span. This span may be free
-// or allocated. If free, it is in one of pageheap's freelist.
-//
-// TODO: Bias reclamation to larger addresses
-// TODO: implement mallinfo/mallopt
-// TODO: Better testing
-//
-// 9/28/2003 (new page-level allocator replaces ptmalloc2):
-// * malloc/free of small objects goes from ~300 ns to ~50 ns.
-// * allocation of a reasonably complicated struct
-// goes from about 1100 ns to about 300 ns.

-# Usage: $progname [OPTION]... [MODE-ARG]...
-#
-# Provide generalized library-building support services.
-#
-# --config show all configuration variables
-# --debug enable verbose shell tracing
-# -n, --dry-run display commands without modifying any files
-# --features display basic configuration information and exit
-# --mode=MODE use operation mode MODE
-# --preserve-dup-deps don't remove duplicate dependency libraries
-# --quiet, --silent don't print informational messages
-# --no-quiet, --no-silent
-# print informational messages (default)
-# --no-warn don't display warning messages

-# -v, --verbose print more informational messages than default
-# --no-verbose don't print the extra informational messages
-# --version print version information
-# -h, --help, --help-all print short, long, or detailed help message
-#
-# MODE must be one of the following:

-# clean remove files from the build directory
-# compile compile a source file into a libtool object
-# execute automatically set library path, then run a program
-# finish complete the installation of libtool libraries
-# install install libraries or executables
-# link create a library or an executable
-# uninstall remove libraries from an installed directory
-#
-# MODE-ARGS vary depending on the MODE. When passed as first option,
