#45264 [NEW]: set_time_limit affects max_execution_time

From: jdm at visi dot com Operating system: Windows PHP version: 5.2.6 PHP Bug Type: Performance problem Bug description: set_time_limit affects max_execution_time Description: ------------ Calling set_time_limit appears to not function as it is documented. Per the documentation: When called, set_time_limit() restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out. According to my test code, it is actually affecting the ini value of max_execution_time. As a result if the time limit is a smaller value, max_execution_time is altered to a smaller value, and script execution time can be cut short. I tracked this result down through drupal with the gallery2 integration module included where it makes calls to set_time_limit(30), which causes the module administration page to be cut short, even though my max_execution_time is defined to be 300 seconds. In my environment, the included code produces the following output: 300 30 Reproduce code: --------------- print '<p>'.ini_get('max_execution_time').'</p>'; set_time_limit(30); print '<p>'.ini_get('max_execution_time').'</p>'; Expected result: ---------------- I would expect the max_execution_time to either not change or be extended by the amount set in set_time_limit, according to the documented operation of it. i.e., the resulting code should produce either: 300 300 or: 300 330 Actual result: -------------- The resulting code produces this output: 300 30 -- Edit bug report at http://bugs.php.net/?id=45264&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45264&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45264&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45264&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45264&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45264&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45264&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45264&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45264&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45264&r=support Expected behavior: http://bugs.php.net/fix.php?id=45264&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45264&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45264&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45264&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45264&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45264&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45264&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45264&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45264&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45264&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45264&r=mysqlcfg
