ID: 24185 Updated by: [EMAIL PROTECTED] Reported By: fulcrum at mbnet dot fi -Status: Analyzed +Status: Closed Bug Type: Documentation problem Operating System: NetBSD PHP Version: 4CVS-2003-06-14 (stable) New Comment:
This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. This is the case on some unices, and is actually in the POSIX 1 standard: In section 5.2.2.4: For each of the following conditions, if the condition is detected, the getcwd() function shall return a value of NULL and set errno to the corresponding value: [EACCESS] Read or search permission was denied for a component of the pathname. So I've documented this and the fact that the return value can be false. Previous Comments: ------------------------------------------------------------------------ [2003-06-14 17:30:54] [EMAIL PROTECTED] At least Linux, OpenBSD, AIX, Solaris and HP-UX implementations of getcwd() should behave the same way. (I didn't test it, just read the man pages I found with google :) ------------------------------------------------------------------------ [2003-06-14 15:14:45] fulcrum at mbnet dot fi 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. ------------------------------------------------------------------------ [2003-06-14 13:44:59] [EMAIL PROTECTED] >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
