ID: 37300 User updated by: astinky at lycos dot com Reported By: astinky at lycos dot com Status: Open Bug Type: Feature/Change Request Operating System: Windows Server 2003 PHP Version: 5.1.3 New Comment:
Ah, thanks. The thing is, this memory intensive script of mine worked fine on php 5.0.5, but its output is truncated on php 5.1.2 and up. It generates no other errors. As well, our upload scripts used to allow a 40 MB file upload on php 5.0.5 and previous versions. I have not tested whether it still does, but I assume it is affected by the changes in memory limit behaviour on windows. Something else has changed with respect to memory use on windows. Perhaps the harcoded memory limit of php has been reduced? If I build 5.1.4 for Win32 from source myself can I enable the memory limit or change the hardcoded limit? (I suspect from your comment I can) Thanks again for your attention to this matter, it is much appreciated. Previous Comments: ------------------------------------------------------------------------ [2006-05-11 10:51:23] [EMAIL PROTECTED] Windows builds ship without memory limit feature. This was done on purpose. I have changed the category to change request since we might consider changing it. ------------------------------------------------------------------------ [2006-05-11 10:10:40] astinky at lycos dot com Additional info/correction: Actually the weserver would fault on shutdown with Apache 2.2.0 - php 5.1.2 (and 5.1.3) if the hardcoded memory limit was exceeded. With Apache 2.2.2 - php 5.1.3 (and 5.1.4) the webserver will fault at the time the memory limit is exceeded. The IIS system mentioned above is running php as an ISAPI. I usually set the memory limit in the php.ini anyway, not in the script. Still it has no effect. If only the fgetcsv function was not so hard on resources I would not be having this issue. I could solve my problem by converting the tab delimited text file I am reading into a MySQL table, but I'd really like to just be able to read the text file in the script so it is more portable. The problem persists in php 5.1.4. I compared the zend_alloc.c of php 5.0.5 to php 5.1.4 and found some suspicious differences, but nothing I could say for sure is responsible. Just let me know if there is any other info I can provide that may help. ------------------------------------------------------------------------ [2006-05-04 02:48:42] astinky at lycos dot com Description: ------------ Re: http://bugs.php.net/bug.php?id=36568 It seems this is not quite fixed. This test script below fails, with no error output and does not echo the memory limit at all. This is on Apache 2.2.2 php 5.1.3 eAcclerator 0.9.5-b2. (tested with eAcclerator disabled - same result) The apache2handler I'm using is self compiled, but I suspect it is not the problem as another server (Windows Server 2003, II6 php 5.1.2 or php 5.1.3 shows similar symptoms) I am using the posted windows binaries for php 5.1.3 and apche 2.2.2 Both servers show an error for the webserver exe in the event log on shutdown with the faulting module varying (php5ts.dll, php_mysql.dll, ntdll.dll, msvcrt.dll...) on previous searches of the bugs here this is always attributed to server misconfiguration. I have been running apache/php for years and am intimately fmiliar with its configuration and have been frustrated by this error appearing in recent php versions. I'm going to take a look at the related php code tomorrow and will reprt any findings I might come up with. I notice previous comments about no support for a memory limit in windows, but I'm sure it worked in php 5.0.5... (tried stting it to -1 which also fails) Thanks for any assistance you can offer. Reproduce code: --------------- <?php echo 'memory_limit: '; ini_set("memory_limit", "32M"); echo ini_get("memory_limit"); ?> Expected result: ---------------- I expect to be able to set the memory limit. (particularly for a script of mine that loads huge arrays from a 2.9 MB tab delimited text file - which worked fine in earler php5 versions but its output is truncated in php 5.1.2 and 5.1.3). I do not expect the webserver to fault on shutdown. Actual result: -------------- Unable to set memory limit, webserver faults on shutdown. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37300&edit=1
