#24185 [Ana]: getcwd() fails if parent directory miss readable-flag

ID: 24185 User updated by: fulcrum at mbnet dot fi Reported By: fulcrum at mbnet dot fi Status: Analyzed Bug Type: Documentation problem Operating System: NetBSD PHP Version: 4CVS-2003-06-14 (stable) New Comment: I have experienced on two servers, one Linux (unkown distro) server running 4.3.1 and an other unkown UNIX (?) computer with the opposite effect (the effect I was expecting myself). Could this be a OS specific issue? Anyways the documenation should be clarified. Previous Comments: ------------------------------------------------------------------------ [2003-06-14 13:44:59] sniper@php.net From "man getcwd": RETURN VALUE NULL on failure (for example, if the current directory is not readable), with errno set accordingly, and buf on success. And as PHP just wraps around this function, the behaviour is the same. ------------------------------------------------------------------------ [2003-06-14 12:44:28] fulcrum at mbnet dot fi Description: ------------ If one of the parent directories of the current working directory doesn't have the readable flag +r (while +x is still specified) getcwd() return false, even though the current directory has full (or at least readable & executale) access (the restrictive permissions apply ONLY to the parent directory). The possible return value of false isn't either mentioned in the documenation. Reproduce code: --------------- mkdir one ; mkdir one/two ; mkdir one/two/three echo "<?php echo gettype(getcwd()).'; '; echo getcwd() ? 'true' : 'false'; ?>" > one/sample.php echo "<?php echo gettype(getcwd()).'; '; echo getcwd() ? 'true' : 'false'; ?>" > one/two/sample.php echo "<?php echo gettype(getcwd()).'; '; echo getcwd() ? 'true' : 'false'; ?>" > one/two/three/sample.php chmod 111 one ; chmod 755 one/two ; chmod 755 one/two/three chmod 644 one/sample.php ; chmod 644 one/two/sample.php ; chmod 644 one/two/three/sample.php Expected result: ---------------- one/sample.php: string; true one/two/sample.php: string; true one/two/three/sample.php: string; true Actual result: -------------- one/sample.php: string; true one/two/sample.php: boolean; false one/two/three/sample.php: boolean; false ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24185&edit=1
