[Announce] Apache Portable Runtime APR 1.7.0 Released
Apache Portable Runtime APR 1.7.0 Released
The Apache Software Foundation and the Apache Portable Runtime
Project are proud to announce the General Availability of version
1.7.0 of the Apache Portable Runtime library (APR). Version 1.6.1
of the APR Utility library (APR-util) and version 1.2.2 of the
APR iconv library (APR-iconv) remain current.
There are a number of specific changes in how APR is deployed
and how APR-util deals with external dependencies in these current
releases, which may be disruptive to existing build strategies:
- The typical cross-process locking stragegy now defaults to
a pthreads lock which will not leak on abnormal process termination,
as opposed to the earlier sysv semaphore locking strategy.
This should result in fewer orphaned locks in misbehaving
applications.
- Netware users should be aware that APR mis-defined the entity
representing an "os mutex", and it was missing a level of
indirection. The new definition should allow the use of the
apr_os_proc_mutex_get/_put API's on the Netware platform but
requires a rebuild against the APR 1.7.0 or later library.
- Expat sources are no longer bundled, this is now an external
dependency. Install libexpat runtime (usually installed by
default) and development packages using your system's package
manager, or from <https://libexpat.github.io/>.
- MySQL support is updated as advised by the MySQL developers.
MySQL versions older than 5.5 should not be used. If you do
use an old MySQL version, use the thread-safe libmysqlclient_r
version of the library.
- FreeTDS partial and incomplete support has been dropped.
Users of MSSQL and SYBASE databases are recommended to use
the ODBC driver instead.
APR 1.7.0, APR-util 1.6.1, and APR-iconv 1.2.2 fix a number
of security vulnerabilities, run-time and build-time issues.

APR, APR-util and APR-iconv are available for download from:

The mission of the Apache Portable Runtime Project is to create
and maintain software libraries that provide a predictable and
consistent interface to underlying platform-specific
implementations. The primary goal is to provide an API to
which software developers may code and be assured of predictable
if not identical behavior regardless of the platform on which
their software is built. We list all known projects using APR
at http://apr.apache.org/projects.html - so please let us know
if you find our libraries useful in your own projects!

It will certainly be at least apr-util 1.7.0, or perhaps apr-2.0.0 which
rolls all of the functionality of the -util library into the apr core. There
have been a number of enhancements over the past year, present
on both branches, which committers are patiently waiting for release.
A cadence, in this case, is of no concern. In terms of maintenance
updates, 1.7.1 releases, I agree a periodic (3 mos or similar) refresh
cycle is helpful, when significant fixes are present and awaiting release.

At least two months would be good. However Apache foo is a *major* piece
of the planetary software ecosystem possibly more so than ISC software.
So a quarterly schedule ( 3 months ) may be more reasonable.

Neither at this time.

I'm aware. There is also the problem of our release tracking, we have
nothing
but apr versions there. I understood there is a mass-export-import facility
which
I'll look into, but basically "1.7.0" and prior all need to become
"apr-1.7.0" etc,
and then we need to import all the historical apr-util-* apr-iconv-* sets.
Before the next release, we aught to split Announcement-x.x.x into distinct
files for the apr, apr-util and apr-iconv groups. As of 2.0.0 these all
merge up,
but in the interim...

I was hoping that we could find a 6-12 week window for publishing the next
release.
Since I started thinking about it, I'm wondering whether we should push
towards apr-util-1.7.0, or just get to apr-2.0.0 already. Other thoughts or
observations?

Thanks, Bill.
Just a quick note. Some of the announcement (expat, MySQL and FreeTDS)
relate not to this APR, but to APR-UTIL updates which are not part of this release.
I know you're keen to get an APR-UTIL update released reasonably soon, and I
promise to tackle at least the XML issues I've been working on when I get back home -
which I anticipate being second half of next week. We also have some further
MySQL updates from an external contributor, which I hope to find time to review
in time for APR-UTIL 1.7.
