Re: [issue] Running site in debugging mode gives internal server error
Ruud, Robert, Mary
searching the textpattern source code shows similar patterns that may trigger this error in other places.
@include/txp_plugin.php@ in(I’ve checked this and textpattern survives fine.)plugin_verify()lib/txplib_db.phpinsafe_query()(fail path makes a similar call)lib/txplib_misc.phpinpluginErrorHandler()andassert_int()
That’s from a txp4.0.5 install but not from svn; so Ruud’s recent feed handler wasn’t covered.

Re: [issue] Running site in debugging mode gives internal server error
Does this also occur in PHP 5.2.4 or 5.2.5?
I mean, if we can’t rely on join() working properly when it is fed a simple array, we might as well dump PHP and switch to a different language.

Does not occur on my localhost (XAMPP, Apache2, PHP 5.2.4). I do not have access to any PHP 5.2.4++ install “in the wild”.

Sorry, I don’t have access to anything higher than 5.2.3 without pulling the source code and learning how to build it myself. As it’s just about midnight here I don’t intend going through that learning curve today :)

I feel the pain there too. Perhaps the news isn’t so bad. <g> It seems the problem is limited to cases where the second is an array directly returned by a function. Thankfully there are just a few of these cases in the source.

Re: [issue] Running site in debugging mode gives internal server error
This one was fixed in 5.2.4. Looks familiar…

I vote for pig latin.
Works correctly for me on my local setup: PHP 5.2.5, Apache 2 module, Windows.

Sounds more acceptable than developing with Klingon bite-code, especially on Windows.

Re: [issue] Running site in debugging mode gives internal server error
Let’s try to get a minimal code example that still triggers this error:
<?php
$callers = join("\n", get_caller(10))
function get_caller($id)
{
$out = array();
$bt = debug_backtrace();
return $out;
}
?>and with a non-empty array.
<?php
level1();
function level1() {level2();}
function level2() {level3();}
function level3() {
$callers = join("\n", get_caller(10));
}
function get_caller($id)
{
$out = array();
$bt = debug_backtrace();
$out[] = 'something';
$out[] = 'else';
return $out;
}
?>Offline

Re: [issue] Running site in debugging mode gives internal server error
I gave both scripts a try and both passed successfully with no segfaults (strange considering I still get segfaults with txp):

Re: [issue] Running site in debugging mode gives internal server error
Both minimal cases run without errors on PHP 5.2.3 and PHP 4.4.7.
Apache’s log entry for the Textpattern abort on PHP 5.2.3: [Wed Jan 9 06:53:10 2008] [notice] child pid 5342 exit signal Segmentation fault (11)

Re: [issue] Running site in debugging mode gives internal server error
strange..i’ve been getting this on my site as well. when i switch to debugging, i get 500 internal error along with huge 10mb core dumps. running php 5.2.1 (as cgi), txp 4.0.6, and apache error reads:
PHP Notice: Undefined variable: out in /home/***/public_html/textpattern/lib/txplib_misc.php on line 343 each time i try to switch to debugging. backend works just fine.
