#50676 [Bgs]: rename across Volumes throws warning "Operation not permitted"

ID: 50676 Updated by: aharvey@php.net Reported By: andreas at heigl dot org Status: Bogus Bug Type: Filesystem function related Operating System: Mac OS X 10.6 PHP Version: 5.3.1 New Comment: The warnings may also be coming from the chown() and chmod() calls that occur between the copy and unlink when the rename call has to be faked across partitions -- there's no way of distinguishing them, since the warnings in php_plain_files_rename() just wrap strerror(). I wonder if this might be worth morphing into a doc bug: the rename manual page currently says that, as of 4.3.3, "rename() is now able to rename files across partitions on *nix based systems", which does seem to be overstating things a little. Something along the lines of "rename() may be able to rename files across partitions on *nix based systems, provided the appropriate permissions are held. Warnings may be thrown if the destination filesystem doesn't permit chown() or chmod() calls to be made on files." might be better.

That does not change the fact that they are a different volume. Please read the underlying documentations for rename and how it works, that may help to understand the limitation. ------------------------------------------------------------------------ [2010-01-14 14:45:05] andreas at heigl dot org I understand, that rename can only operate on the same volume (like the move-command). But unlike in windows on a Mac (as on any other UNIX-like environment) volumes can be mount anywhere in the folder-hirachy, so that it is rather difficult to check whether source and target of the rename are on the same volume or not. And as I pointed out in the original bug-report, the source-file actually is deleted, so there is no need for the error message. ------------------------------------------------------------------------ [2010-01-14 13:56:49] iliaa@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php rename() can only work "normally" when operating on the same volume. In your case it emulates rename via copy & delete. I would guess since it cannot delete file from the original volume, it gives you an error message. ------------------------------------------------------------------------ [2010-01-11 12:59:23] p dot szalko at gmail dot com The same bug is in PHP 5.2.11 and Mac OS X 10.5 ------------------------------------------------------------------------ [2010-01-06 10:16:00] andreas at heigl dot org Description: ------------ When renaming files acros Volumes a warning is triggered that the "Operation is not permitted. The operation is executed though. Reproduce code: --------------- - Create two images and mount them (Image1, Image2). - Disable the 'Ignore Owner'-Feature on both of them and set permissions so the WebServer can access the files. - Add a file to one of the mounted volumes (touch /Volumes/Image1/testfile) ini_set ( 'error_reporting', E_ALL ); ini_set ( 'display_errors', true ); rename ( '/Volumes/Image1/testfile', '/Volumes/Image2/testfile' ); Expected result: ---------------- The file /Volumes/Image1/testfile has been copied to /Volumes/Image2/testfile ad the original file has been removed. No error should be triggered Actual result: -------------- The file /Volumes/Image1/testfile has been copied to /Volumes/Image2/testfile ad the original file has been removed. Additionally the following error is triggered: rename(/Volumes/Image1/testfile,/Volumes/Image2/testfile): Operation not permitted in renametest.php on line n ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50676&edit=1
