Req #43593 [Opn-Fbk]: Impossible to disable Zend Memory Manager in anything other than CLI SAPI
Edit report at https://bugs.php.net/bug.php?id=43593edit=1 ID: 43593 Updated by: m...@php.net Reported by:phajdan dot jr at gmail dot com Summary:Impossible to disable Zend Memory Manager in anything other than CLI SAPI -Status: Open +Status: Feedback Type: Feature/Change Request Package:Compile Failure Operating System: Linux Gentoo 2007.0 PHP Version:5.2CVS-2007-12-14 Block user comment: N Private report: N New Comment: Works fine here. What SAPI are you using? /usr/share/nginx/html$ USE_ZEND_ALLOC=0 PHP_FCGI_CHILDREN=0 php-cgi -b 0: $ curl --progress localhost/info.php | grep Memory Manager trtd class=eZend Memory Manager /tdtd class=vdisabled /td/tr It's really just coming from the environment: http://lxr.php.net/xref/PHP_TRUNK/Zend/zend_alloc.c#2723 Previous Comments: [2008-02-02 09:18:42] phajdan dot jr at gmail dot com After compiling with that option Zend MM is still enabled, according to phpinfo(). Anyway, it must be possible to somehow disable it, because debug build does it. But it would be not a good solution to use debug build in production. Please, please check it yourself, *seriously* - no guessing, not requiring me to check every opportunity. [2008-02-01 22:48:39] j...@php.net How about --disable-malloc-mm ?? [2008-01-29 07:06:10] phajdan dot jr at gmail dot com Well, reproduction script is *not*needed* as it's a PHP configuration setting issue. It is visible for example in ? phpinfo(); ? and I gave exact *steps* to reproduce at the beginning. Here they are, for convenience: The goal is to disable the Zend Memory Manager. Try #1: 1. set USE_ZEND_ALLOC in the environment (/etc/profile) 1a. also tried other ways, like setting it in the Apache config (SetEnv etc) 2. Restart Apache to make sure change takes effect 3. View phpinfo page to see if Zend Memory Manager got disabled 3a. But this way works for the CLI version of PHP (setting env in /etc/profile). Try #2: (proven to be futile and ineffective, but anyway) I tried to recompile PHP with ./configure switches like --disable-zend-memory-manager or --enable-malloc-mm (some webpages told they will disable Zend MM), but as other developers said in this report, there are no such compile options. [2007-12-17 10:59:06] phajdan dot jr at gmail dot com So the bug I referred to was http://bugs.php.net/bug.php?id=43397. Curently it's marked as a duplicate of some other bug, which is now closed because of lack of feedback. I tried to request reopening my original bug, unfortunately without success. About setting env var - please note that I tried this method. No go. phpinfo shows that Zend Memory Manager is enabled. Note that I didn't set it from command line, but had in environment (something like export USE_ZEND_ALLOC=0; /usr/sbin/httpd ...). But it shouldn't make a difference. [2007-12-17 10:00:38] sni...@php.net How about you tell us what the crash is you get? (what bug id was the one you reported?) Also note that some crash bugs were fixed recently. And there are no -disable-zend-memory-manager or --enable-malloc-mm configure options. To disable the memory manager (for debugging) you start e.g. apache with same way you do with PHP CLI: # USE_ZEND_ALLOC=0 /usr/sbin/httpd your options here The remainder of the comments for this report are too long.

[2008-01-29 00:23:03] [EMAIL PROTECTED] Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with ?php and ends with ?, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.
