Subject: php5-mysql: mysql[i]_connect() fails without error message

Date: Tue, 29 Mar 2011 12:22:17 +0200

[Message part 1 (text/plain, inline)]

Package: php5-mysql
Version: 5.3.3-7+squeeze1
Severity: important


A complex PHP application fails since the upgrade from lenny to squeeze.
The final statement is a mysql_connect() (or mysqli_connect() with no
difference) which fails (i.e. does not return a handle) without any obvious
reason and without providing an error message or an error number.

This bug does occur only on some pages; it has been reproducible after some
efforts, but only in the whole context of the application. The behaviour is
as follows: calling some known PHP program over the web triggers the bug
(though the program itself finishes completely fine). After this, every
call to the same apache process fails with the problem stated above. (This
is why I am unsure whether the bug is in php-mysql at all; the real cause
might as well be somewhere in php-common).

Changes to the application in unrelated places of the code can make the bug
occur / vanish, not following any clear pattern => so I was not able to
isolate the real source of the problem. The behaviour of the problem makes
it feel like some memory over write in C, but I am definitely not capable
of debugging it on my own.

After some usenet discussion (in German) following the initial posting
<1t4d66471bi1665n3e9%sfroehli@Froehlich.Priv.at> I got to the conclusion
that the problem is within PHP, so I compiled a stock version of PHP-5.3.6
to /usr/local and used it instead of the Debian package. This solved the
issue up to now.
