#49762 [NEW]: unlink can't handle posix acls

From: jonas at brachium-system dot net Operating system: Debian Lenny PHP version: 5.2.11 PHP Bug Type: Filesystem function related Bug description: unlink can't handle posix acls Description: ------------ the php function unlink can't handle posix acls. The function is_writeable **can** handle posix acls. See #34957 my acl on file 'foo': ---------------------- # file: foo # owner: jonas.genannt # group: users user::rw- group::r-x #effective:r-- group:www-data:rw- mask::rw- other::--- The php script runs as user www-data and group www-data. The function unlink fails on posix acls but is_writeable seems to be handling posix acls. Reproduce code: --------------- <?php if (is_writeable('foo')) { echo "fooo is Writeable<br/>"; if (unlink('foo')) { echo "Removed!"; } else { echo "NOT REMOVED!<br/>"; } } ?> Expected result: ---------------- fooo is Writeable Removed Actual result: -------------- fooo is Writeable Warning: unlink(foo) [function.unlink]: Permission denied in test.php on line 4 NOT REMOVED! -- Edit bug report at http://bugs.php.net/?id=49762&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49762&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49762&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49762&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49762&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49762&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49762&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49762&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49762&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49762&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49762&r=support Expected behavior: http://bugs.php.net/fix.php?id=49762&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49762&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49762&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49762&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49762&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49762&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49762&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49762&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49762&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49762&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49762&r=mysqlcfg
