Bugzilla Bug 209501

Last night I upgraded dev-lang/php to version 5.2.5_p20080206. Since then,
every attempt to go to a php-enabled page gives a '500 internal server' error.

I've tried restart, reinstalling lighttpd and all, nothing worked. Downgrading
to dev-lang/php-5.2.5-r1 fixed the problem immediately.

The problem seems similar to the one described here:
http://forum.lighttpd.net/topic/34454
http://bugs.php.net/bug.php?id=43476

Reproducible: Always

Steps to Reproduce:
1. Upgrade to dev-lang/php-5.2.5_p20080206
2. Try to visit any php-enabled page

Actual Results:  
"500 internal server error"

Lighttpd error log shows:
2008-02-10 09:59:00: (mod_fastcgi.c.2462) unexpected end-of-file (perhaps the
fastcgi process died): pid: 4078 socket:
unix:/var/run/lighttpd/lighttpd-fastcgi-php-4035.socket-3 
2008-02-10 09:59:00: (mod_fastcgi.c.3254) response not received, request sent:
885 on socket: unix:/var/run/lighttpd/lighttpd-fastcgi-php-4035.socket-3 for
/gallery/main.php , closing connection

Expected Results:  
Page should display normally like it does with 5.2.5-r1.

Hmmm, it works perfectly fine here.

Certainly not related to php+lighttpd -- it works perfectly fine here (on
multiple machines). The problem rather seems to be that php crashes -- are you
using any extensions, especially Zend extensions like ZendOptimizer by chance?

Yeah more like http://bugs.php.net/bug.php?id=43387 if anything.

Nope, no extensions. I only use php for gallery. Here are the use flags for the
packages involved (mysql is installed minimal because the actual database is on
another server):

Perhaps it's related to my architecture? Wouldn't be the first time things work
fine on x86 but break on sparc...

This won't get us anywhere, need a backtrace:

http://www.gentoo.org/proj/en/qa/backtraces.xml

I cannot reproduce this on my x86 machine.
It really seems sparc related.

Same problem here on one machine (emerge --info below). Another works. Strange.

Can you please try php-5.2.5_p20080206-r2 which I just added to the tree? It
contains the fix for bug 209606 and this bug might actually be the same.
Simply make this bug a dupe of bug 209606 if this is the case.

If it doesn't fix the problem, please try to generate a backtrace.

Thanks.

Test -r3 instead please (if you don't want to wait on rsync:
-PHP_PATCHSET_REV="2"
+PHP_PATCHSET_REV="3"

It's supposed to include a fix which does not break other things...

php-5.2.5_p20080206-r3 seems to fix it for me. I'll do a bit more testing just
to make sure, but the initial results are looking good. :-)

See bug #208418, comment #23 and onward.

Bug #209418, comment #23 and onward, of course.

Gah, third time lucky: bug #209148, comment #23 and onward, of course.
Sorry for the superfluous messages.

So it is still broken for you... bad :P
The symptoms are really the same, right? I.e. things like <?php phpinfo(); ?>
work fine?
I guess we need to do the hard and long process of trying to reproduce this
with a vanilla snapshot, getting a useful backtrace and finally filing another
upstream bug.
Regarding src_test issues -- I've done yet another change to the in-tree
version of -r3 (no revbump) which should finally fix it (old logic was wrong,
my first attempt at fixing it (>=-r2) missed one thing as well, so...).

Also I find it quite astonishing to see so many QA warnings -- I've never seen
them before. Have they been there on hppa for a longer time or did they appear
just recently?



Btw, can anyone else still reproduce this problem?

I cannot reproduce this any longer with -r3

-r3 works for me too

-r3 segfaults for me - at least with the debug useflag disabled :o
i didn't managed to get a useful backtrace unfortunatly...

Sure. Of course.

Er, why not simply start out from the last known good version? Or why not patch
that one with the fixes needed to close the vulnerabilities of bug #209148?

I will try it out. It won't help fixing *this* bug though.

Try adding -Wall to your CFLAGS.

Seriously, similar snidy remarks are totally not welcome. If you like, you can
go and maintain PHP yourself, with the sucky totally uncooperative upstream
that doesn't give a damn about any security issues and the only fixes go to CVS
trunk.

What kind of question is that - whether anyone can reproduce the problem
because we simply can't, like it or not. It just works here and doesn't
segfault or anything, otherwise noone would ask for stabilizing this... Answer
the question, post backtraces or whatever and keep similar remarks directed to
/dev/null, ktnxbye.

It wasn't a sneer.

I'm still having the problem of php crashing sometimes. This is an installation
using fastcgi/lighttpd. As you can see, it's a plain old x86 machine. 

I'll try and get a backtrace - but the crashes are too infrequent to reliably
get a trace.
