Bug #51404 [Com]: is_dir() returns false on cifs mounted share

Edit report at http://bugs.php.net/bug.php?id=51404&edit=1 ID: 51404 Comment by: digitalaudiorock at gmail dot com Reported by: neversaynever at tut dot by Summary: is_dir() returns false on cifs mounted share Status: Bogus Type: Bug Package: Directory function related Operating System: Linux PHP Version: Irrelevant New Comment: I have to agree with the original poster. Running php 5.2.13 Under Gentoo I have problems with is_dir() on CIFS shares with 2.6.31 and 2.6.32. On a machine I have running 2.6.30 I don't see the issue. Here's a CIFS mounted directory that reports is_dir() as false even though chdir() reports true: php -r 'var_dump(is_dir("/home/tom/mount/sql"));' bool(false) php -r 'var_dump(chdir("/home/tom/mount/sql"));' bool(true) Here's the equivalent in perl that reports true: perl -e '(-d "/home/tom/mount/sql") && print "OK\n"' OK ls -ald /home/tom/mount/sql drwxr-xr-x 1 tom tom 0 Apr 28 2008 /home/tom/mount/sql That's a windows share mounted as administrator of the windows machine. While this may be caused somehow by CIFS changes in the kernel, there truely is something ugly going on here and it's caused me some serious problems.

You get what your stat() returns -> not PHP problem. ------------------------------------------------------------------------ [2010-03-26 20:34:07] neversaynever at tut dot by Description: ------------ I upgraded my kernel to 2.6.31 (stable) and has php-5.2.12 (stable), but php function is_dir() returns false for folder on my cifs mounted share. strace php -r 'var_dump(is_dir("/path_to_mounted_folder/"));' ... stat64("/path_to_mounted_folder/", {st_mode=S_IFDIR|0755, st_size=32768, ...}) = 0 gettimeofday({1269602972, 30466}, NULL) = 0 write(1, "bool(false)\n", 12bool(false) ) = 12 ...
