#32744 [NEW]: possible twice including by require_once() after chdir()

From: vovik at getart dot ru Operating system: Windows XP PHP version: 4.3.11 PHP Bug Type: Filesystem function related Bug description: possible twice including by require_once() after chdir() Description: ------------ When script started and do require_once() by relative filename, this function remembers lower case real path. If script changes working dir via chdir() and directory name consist of not lower-case letters, require_once() will include the file again. Reproduce code: --------------- <?php // This file located under directory with non-lowercase name, i.e. "TesT" print "<pre>"; require_once("./inc.php"); // single print line there chdir("./.."); chdir("./TesT"); require_once("./inc.php"); var_dump(get_included_files()); ?> Expected result: ---------------- I expect to single include of inc.php. Actual result: -------------- Actually, got two :) -- Edit bug report at http://bugs.php.net/?id=32744&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=32744&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=32744&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=32744&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=32744&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=32744&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=32744&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=32744&r=needscript Try newer version: http://bugs.php.net/fix.php?id=32744&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=32744&r=support Expected behavior: http://bugs.php.net/fix.php?id=32744&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=32744&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=32744&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=32744&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=32744&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=32744&r=dst IIS Stability: http://bugs.php.net/fix.php?id=32744&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=32744&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=32744&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=32744&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=32744&r=mysqlcfg
