5.0.0 Test Roll is working fine for me, including the sqlite 2.8.14 upgrade.

Thanks!

The file_get_contents() bug still seems to be present in the test roll, but
not in the latest snap:

Reproduce code (from the bug report for 29099):
--------------

#!/usr/bin/php
<?php
$ch = curl_init("http://www.php.net/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$str1 = curl_exec($ch);
curl_close($ch);

$str2 = file_get_contents("http://www.php.net/");

echo $str2;  // Note garbage at end of string

if ($str1 != $str2) {
echo "Both results differ.\n";
} else {
echo "Both results are the same.\n";
}



The latest snap (200407130430) seems to be just fine though.

I moved those to http://www.php.net/~andi/ and renamed them from RC4
(which it is not of course) to -pre-release-test in order to avoid
confusion later on.

Hi, I'm new to the list, so forgive me if I'm going about this the wrong
way.


I'm still experiencing  the bug: http://bugs.php.net/bug.php?id=28829
(Crashes when BC Math functions get an argument of 0) with this
release.  I have no problems duplicating it and should be around for a
while if  someone needs more information, or is unable to duplicate it.

Chris

P.S. I'm not really a C++ guy, I have Visual Studio 6 installed on this
machine, so I have access to its tools, but I'm not very good at using
them. I mostly joined this list to lurk, but I'm willing to help where
I'm able.

I'm glad you spoke up first Chris, because I have questions in a similar
vein.  Namely, how can I help?  I have a few years of C under my belt, but
I never got to the point where I'd be comfy hacking PHP.  (I'd like to get
there eventually, I'm just not there yet.)

So, am I being lazy, have I missed some docs on the web regarding how to
be useful, or how to become familiar enough with the PHP code to start
lending a hand with the debugging?  Or are we expected to learn it
ourselves, on our own, in order to be accepted into "the club" as it were?
(Not that there's anything wrong with that, it's just that a lot of groups
require self-validation like that.)

Thanks for any help,
Dan

The general method of helping out (at first) is to review open bug
reports and post patches to this list. Someone will then review and
merge into the code base.

A pattern of good patches leads to greater CVS karma, so you can apply
them yourself.

If you're not up for that right now, you could go through open reports
and help classify them, provide reproducing test cases (and/or
backtraces), mark them as bogus, etc.

There's no good online "here's how PHP's C internals work," but
George's "Advanced PHP Programming" book is a good place to start
reading.

yep, this bug is still present. i would like to say, that this bug is real
pain in the ass for windows users, because this extension cannot be turned
off and it causes some pear packages to be unuseble (i know of Benchmark,
probably everything that uses it is crushing too). please fix this guys :/

Are you sure you're not loading old extensions?

Completly sure! I've also tried to disable all extensions and it still
segfaults.

Dunno if it's the right thing to add if()'s around emalloc(), but with
attached patch these warnings disappear, reducing valgrind logs in a
half.

Are you sure you don't have some stale build? I checked the same tests with

Okay. Tag wise it's RC4 because I couldn't come up with something better
and didn't want to screw up the CVS tag names.

Can someone reproduce this? I couldn't. Not in debug nor in release.

I tried pre-release-test package on "php -m" : Does not segfault at home
with standard conf.
So I tried activating all extensions. I had a lot of dependencies Warnings
(normal) but no segfault...

I can repeatedly reproduce this with cli (php -m) and apache2 (just starting
and stopping it) apache 2 crash probably same as bug 29025 - though with or
without xsl doesnt matter). cgi seems to be fine. Always same stack trace.

I don't know the internals of PHP, but a hash table parameter of 0xcdcdcdcd
looks an awful lot to me like there's a debug malloc library of some sort that
fills freed memory with '\xcd', meaning that zend_hash_destroy() is being
called with previously freed memory.

Since php_shutdown_stream_wrappers() calls zend_hash_destroy() three times,
but the first and third call (directly or indirectly) pass a parameter which
is simply the address of a variable, my first guess would be that this call:

zend_hash_destroy(php_get_stream_filters_hash())

is the culprit, which implicates the variable 'stream_filters" in some way,
shape or form (via the function _php_get_stream_filters_hash() in
filters.c:41.

I hope maybe this helps someone who knows the code determine the problem.  I
did a cursory search for something pertaining to 0xcd and could not find it,
but maybe someone more familiar with the code will recognize 0xcdcdcdcd...

Yes, it definitely looks as if ht was freed previously.

Probably fixed now in CVS; looks like Sara forgot to change this last
thing as part of her filter thread safety fix.

Indeed.  Thought I'd grepped for all occurances of
php_get_stream_filters_hash(), don't know how I missed that one given that
it was a dozen lines below the initialization!  Also seems like one of the
userfilter regression tests should have caught it.

Anywho, Thanks Wez.
