[VOTE] Release Tomcat Connectors 1.2.30
Hi,
We have one serious bug with 1.2.29 that causes IIS to
crash on POST request.
http://issues.apache.org/bugzilla/show_bug.cgi?id=48826
Other web connectors are not affected by that bug
Please test the provided release so we can replace the
existing 1.2.29 ASAP.
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/
Sources can be found at:
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/source/jk-1.2.30/
I have made windows binaries available at:
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/binaries/win32/jk-1.2.30/
http://tomcat.apache.org/dev/dist/tomcat-connectors/jk/binaries/win64/jk-1.2.30/
Documentation is available at:
http://people.apache.org/~mturk/connectors-doc-1.2.30/
and a changelog is:
http://people.apache.org/~mturk/connectors-doc-1.2.30/miscellaneous/changelog.html
The vote will be closed as soon enough votes are encountered.
Apache Tomcat Connectors 1.2.30 is:
[ ] Stable - no major issues, no regressions
[ ] Beta - at least one significant issue -- tell us what it is
[ ] Alpha - multiple significant issues -- tell us what they are
Regards

What 'c' flag does is to actually call _commit (FlushFileBuffers)
on fflush(). Without that the fflush is called when the stream
buffer is full. That makes problems if used from multiple
processes since it can create complete garbage in the log.

AFAICT a+c does what a+ does on posix on fflush()

One addition: the combination of the a+c mode and fflush() shows the
problem. As soon as I remove one of the two, perforemance is fine.
It's unfortunate, that the OS doesn ot allow to specify a fflush
interval, e.g. the file should be flushed every 500 ms. There's a
flushall() call, that could be used for something like that...

But now there should be no problems with cross worker

???
I'm building on win32 box.
You have done something wrong with setting the environment.
Use the Server 2003 SDK then
SetEnv.cmd /XP64 /RETAIL
nmake -f Makefile.amd64
and
SetEnv.cmd /SRV64 /RETAIL
nmake -f Makefile.ia64

Right, I cannot say in 1.2.30 it was released before releasing it.
Thanks for thorough testing

I'm not seeing this on Windows XP - I get many logs per clock slice. (I
tried it with my builds, and Mladen's 1.2.27/28/30 builds).

Thanks for RMing and producing the Windows binaries.
A couple of test result, none of them showstoppers:
1) Logging Performance on ISAPI/Windows
The logging changes for Windows seem to dramatically slow down log
performance. That's not a problem when having only occasional info etc.,
but when switching to debug or trace log operation ow gets really slow.
E.g. shutting down takes about 5 minutes, one jkstatus call more than a
minute. I did not built with explicit JK_LOG_LOCKING define, so maybe
it's the mode 'a+c' change. Didn't have time for one more test. 1.2.28
does not show that behaviour. There we can log about 20 lines before the
clock advances by one 15ms tick, with 1.2.30 each log line takes between
15 and 200 ms.
As said: not a problem as lng as we have usual operation.
2) Chunking ISAPI/Windows
I observed, that recent Firefox doesn't finish receiving jkstatus
response. Although the full page is shown, the browser status shows it
is waiting for more. The same was true already for 1.2.28. I didn't test
any other browser, nor any other dynamic content page. Unfortunately I
couldn't do a network trace today, because Browser and server were on
the same box.
3) URL to worker mapping
My test comfiguration contained a mapping for /* and another one for
/jkstatus. When sending a request for /jkstatus, the /* map was chosen.
It seems the plugin should have chosen the /jkstatus map, because it is
more precise. Did not yet check, whether that's new.
4) Libtool 2 and old Solaris, mod_jk for Apache 1.3
You prepared the source using libtool 2. Unfortunatly libttol 2 contains
shell constructs, that do not work with each shell. On Solaris 8 /bin/sh
throws errors on the libtool script. Ususally one chooses
CONFIG_SHELL=/bin/ksh, but our Makefiles do not fully support that and
nevertheless choose SHELL, which is /bin/sh. Will fix next week.
5) ISAPI build
MS VC does support cross compilation, e.g. preparing bins for AMD64 or
IA64 on a 32 Bit environment. What goes wrong here is, that ISAPI needs
PCRE, and during PCRE build we compile a binary dftables and then run
it. So when you compile e.g. for 64 Bits, dftables will also be compiled
for 64 Bits and then it will not run. You wont notice, if you first
compile for your build platform, because then dftables works and
produces the needed output file and afterwards you can build for other
target environments. Not optimal.
6) Docs
The 2010 news page is only part of the main menu, but missing from the
menus on the other pages (various project.xml files). The index and 2010
news page still refer to 1.2.29 as being released.

Rainer

I've noticed an issue with the IIS shutdown being blocked, but I'm pretty
sure it's not a regression.

Tested with some RIA apps that utilise POST heavily, replicated the 1.2.29
issue and verified 1.2.30 resolves it.
(I sent this earlier, but I'm getting mail delivery and receiving failures
today)

I don't test with IIS, though ;)
