From: simon at stienen dot name Operating system: FreeBSD 7.1-RELEASE/amd64 PHP version: 5.2.9 PHP Bug Type: Filesystem function related Bug description: unlink won't delete symlinks without a target
Description: ------------ unlink()ing a symlink with its target missing fails with an open_basedir error. This might be related to http://bugs.php.net/bug.php?id=20235 (actual deletion changed, but sanitization still uses target?) and/or http://bugs.php.net/bug.php?id=29145 (missing target (empty string?) is considered to be outside of open_basedir?) Reproduce code: --------------- <?php echo "creating link\n"; symlink('nonexisting_target', 'link'); echo "unlinking link\n"; unlink('link'); echo "creating target\n"; file_put_contents('nonexisting_target', 'foo'); echo "unlinking link (again)\n"; unlink('link'); echo "unlinking target\n"; unlink('nonexisting_target'); Expected result: ---------------- Run with php -d open_basedir= creating link unlinking link creating target unlinking link (again) Warning: unlink(link): No such file or directory in /tmp/- on line 13 unlinking target Actual result: -------------- Run with php -d open_basedir=/ creating link unlinking link Warning: unlink(): open_basedir restriction in effect. File(link) is not within the allowed path(s): (/) in /tmp/- on line 7 creating target unlinking link (again) unlinking target -- Edit bug report at http://bugs.php.net/?id=48111&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48111&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48111&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48111&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48111&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48111&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48111&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48111&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48111&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48111&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48111&r=support Expected behavior: http://bugs.php.net/fix.php?id=48111&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48111&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48111&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48111&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48111&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48111&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48111&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48111&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48111&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48111&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48111&r=mysqlcfg
