Bug description: unlink can't handle posix acls
Description:
------------
the php function unlink can't handle posix acls. The function is_writeable
**can** handle posix acls. See #34957
my acl on file 'foo':
----------------------
# file: foo
# owner: jonas.genannt
# group: users
user::rw-
group::r-x #effective:r--
group:www-data:rw-
mask::rw-
other::---
The php script runs as user www-data and group www-data.
The function unlink fails on posix acls but is_writeable seems to be
handling posix acls.
Reproduce code:
---------------
<?php
if (is_writeable('foo')) {
echo "fooo is Writeable<br/>";
if (unlink('foo')) {
echo "Removed!";
}
else {
echo "NOT REMOVED!<br/>";
}
}
?>
Expected result:
----------------
fooo is Writeable
Removed
Actual result:
--------------
fooo is Writeable
Warning: unlink(foo) [function.unlink]: Permission denied in test.php on
line 4
NOT REMOVED!
