#36868 [NEW]: fopen does not set errno for posix_get_last_error

From: dgatwood at mac dot com Operating system: Mac OS X PHP version: 5.1.2 PHP Bug Type: POSIX related Bug description: fopen does not set errno for posix_get_last_error Description: ------------ On Mac OS X, when fopen() fails with a permission denied error, the result of a subsequent posix_get_last_error() call is zero (0). I would expect this to be set to the value of errno returned by the underlying open or fopen call. I would also expect this to work for put_file_contents, but also get a rather useless zero when calling posix_get_last_error() after that fails. However, since that isn't a POSIX function, I can accept that it wouldn't behave in this way... but fopen is a standard POSIX function, and should be setting errno. Currently, it appears that without explicitly doing a stat on the directory, it is impossible to distinguish a permissions problem from some other error return (e.g. file exists, I/O error, etc.). Reproduce code: --------------- $fp = fopen("/unwritabledirectory/filename", "w"); if (!$fp) { print "Error was: ".posix_get_last_error().".\n"; } Expected result: ---------------- I would expect the fopen to fail with a permission denied error, errno to be set appropriately, and posix_get_last_error () to fetch that value. Actual result: -------------- Error is always zero (0). -- Edit bug report at http://bugs.php.net/?id=36868&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36868&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36868&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36868&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36868&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36868&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36868&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36868&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36868&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36868&r=support Expected behavior: http://bugs.php.net/fix.php?id=36868&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36868&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36868&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36868&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36868&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36868&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36868&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36868&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36868&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36868&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36868&r=mysqlcfg
