#42587 [NEW]: behaviour change regarding symlinked .php files

From: christian at hoffie dot info Operating system: Linux 2.6 PHP version: 5CVS-2007-09-07 (snap) PHP Bug Type: CGI related Bug description: behaviour change regarding symlinked .php files Description: ------------ php-5.2.4 changed the behaviour for the current working directory (cwd) which php scripts see when the requested php file is a symlink which points to a php file in another directory. It is still reproducible with php5.2-200709071230 (snapshot). php-5.2.3 worked fine. Reverting this commit [1] solves the problem. I'm using the tarballs from php.net, no patches. This change breaks certain Typo3 setups. [1] http://cvs.php.net/viewcvs.cgi/php-src/sapi/cgi/cgi_main.c?r1=1.267.2.15.2.42&r2=1.267.2.15.2.43&pathrev=PHP_5_2 (Fixed bug #40419 (Trailing Slash in CGI request don't work)) Reproduce code: --------------- (a web server, lighttpd in this case, is set up at 127.0.0.1:8000; foo.php5.2.3 is handled by php5.2.3, foo.php5.2.5dev by php5.2-200709071230; both binaries have the -n option passed; docroot is /var/tmp/php) christian@tux /var/tmp/php $ mkdir foo christian@tux /var/tmp/php $ echo '<?php print getcwd(); ?>' > foo/bar.php christian@tux /var/tmp/php $ ln -s foo/bar.php bar.php5.2.3 christian@tux /var/tmp/php $ ln -s foo/bar.php bar.php5.2.5dev christian@tux /var/tmp/php $ curl http://localhost:8000/bar.php5.2.5dev /var/tmp/php/foo christian@tux /var/tmp/php $ curl http://localhost:8000/bar.php5.2.3 /var/tmp/php Expected result: ---------------- >=php-5.2.4 should behave exactly as <php-5.2.4; above commands should show "/var/tmp/php" (= the directory of the symlink; not the directory of the target of the symlink). Actual result: -------------- getcwd() returns /var/tmp/php/foo -- the directory which contains the target of the requested symlink. -- Edit bug report at http://bugs.php.net/?id=42587&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42587&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42587&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42587&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42587&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42587&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42587&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42587&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42587&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42587&r=support Expected behavior: http://bugs.php.net/fix.php?id=42587&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42587&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42587&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42587&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42587&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42587&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42587&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42587&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42587&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42587&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42587&r=mysqlcfg
