#38577 [Bgs]: ini settings leak between virtual hosts with Apache 1.3

ID: 38577 User updated by: php at diptyque dot net Reported By: php at diptyque dot net Status: Bogus Bug Type: Apache related Operating System: FreeBSD 4.4 PHP Version: 4.4.4 New Comment: IMHO, the latest mbstring-related bug fix in PHP 5.2.1 has much more in common with the problem I reported than those bug report numbers you previously pointed to (!?) see http://bugs.php.net/bug.php?id=39361 ; mbstring function overloading - done although not activated Previous Comments: ------------------------------------------------------------------------ [2006-10-18 21:09:18] tony2001@php.net See bug #38670 and bug #38566. Please use bug #38760 for further comments. ------------------------------------------------------------------------ [2006-09-08 09:02:47] php at diptyque dot net I'm not trying anything. You told me to download and install the latest CVS snapshot. That's what I did but the erratic function overloading behavior is still there. Considering no drastic changes have been made since v4.4.4 either at the Apache SAPI level (mod_php4.c) or in Mbstring (mbstring.c) source code, this isn't very surprising. Regarding Xdebug, this particular extension also overrides two core functions -- namely var_dump() and set_time_limit (). Don't you think it would be interesting to know if the function overloading that Xdebug performs is sticky or not when running under the Apache 1.3 SAPI? I have the strong feeling that the original PHP function table state is not restored properly by Mbstring but I don't have the time nor the resources needed to nail down further the origin of the leak -- i.e. the overridden functions stickiness or whatever you may call it. ------------------------------------------------------------------------ [2006-09-07 16:48:46] tony2001@php.net I'm not sure I understand what you're trying to do and to say. ------------------------------------------------------------------------ [2006-09-07 16:39:49] php at diptyque dot net FYI, I do *NOT* have any Zend or Xdebug extension installed... I have downloaded Xdebug only to compare its overriding technique with the one used in Mbstring extension. =begin [diptyque] % php -m [PHP Modules] bz2 ctype curl gd imap mbstring mysql openssl overload pcre posix readline session sqlite standard tokenizer xml zlib [Zend Modules] =end BTW, I compared source files for apache SAPI (./sapi/apache/mod_php4.c) and mbstring extension (./ext/mbstring/mbstring.c) between version 4.4.4 and latest stable version and did not find anything different (!?) ------------------------------------------------------------------------ [2006-09-07 15:25:39] tony2001@php.net Please remove all zend_extensions, including XDebug and try again. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
