Bug description: is_writable returns 'true' on read-only files over NFS
Description:
------------
When using is_writable() on a read-only file mounted over NFS, it
incorrectly returns true. In our environment, the NFS server is running
MacOSX Server 10.5 mounted with the following fstab options:
10.10.10.10:/Volumes/Sack /sack nfs
rw,rsize=32768,soft,intr,tcp,nosuid 0 1
Reproduce code:
---------------
[EMAIL PROTECTED] /tmp $ ls -ld /sack/test
dr-xr-xr-x 2 joshbug mudbug 68 Oct 6 14:45 /sack/test/
[EMAIL PROTECTED] /tmp $ ls -ld /tmp/test
dr-xr-xr-x 2 joshbug mudbug 4096 Oct 6 14:44 /tmp/test/
[EMAIL PROTECTED] /tmp $ cat is_writable_test.php
<?php
var_dump(
is_writable('/sack/test'), // /sack is the NFS mount
is_writable('/tmp/test')
);
[EMAIL PROTECTED] /tmp $ php -f is_writable_test.php
Expected result:
----------------
bool(false)
bool(false)
Actual result:
--------------
bool(true)
bool(false)
