#50386 [NEW]: Strange realpath() behavior in shutdown functions

From: dzlatanov at softproekt dot com Operating system: Linux / Windows PHP version: 5.2.11 PHP Bug Type: *Directory/Filesystem functions Bug description: Strange realpath() behavior in shutdown functions Description: ------------ I noticed that realpath() function does not return the same result when called during the regular script execution and in the shutdown process. This behavior only appears when PHP is running as Apache module, but not in CGI/FastCGI mode. Tested with PHP 5.2.6, 5.3.0, 4.4.8. Reproduce code: --------------- <?php function MyShutdownFunc() { echo realpath("./") . "<br />"; } MyShutdownFunc(); register_shutdown_function("MyShutdownFunc"); ?> Expected result: ---------------- /www/mysite.com/staging/root /www/mysite.com/staging/root Actual result: -------------- /www/mysite.com/staging/root / -- Edit bug report at http://bugs.php.net/?id=50386&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50386&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50386&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50386&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50386&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50386&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50386&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50386&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50386&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50386&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50386&r=support Expected behavior: http://bugs.php.net/fix.php?id=50386&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50386&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50386&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50386&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50386&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50386&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50386&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50386&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50386&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50386&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50386&r=mysqlcfg
