Summary: glob returns error, should be empty array()
Status: Bogus
Type: Bug
Package: Safe Mode/open_basedir
Operating System: FreeBSD 7.1
PHP Version: 5.2.9RC1
Block user comment: N
Private report: N
New Comment:
It seems to me, that "glob" is returning false, even though the path i try to
glob
is valid compared to the "open_basdir" settings. Could you please have a
further
look at this issue?
(tried this with php 5.3.6 and php 5.3.8, btw.)

"an empty array if no file matched" is what i see in the manual.
but this returns error, and not an empty array()
glob("/path/allowd/in/open_basedir/nonexitentfile.*");
I can understand why a system glob call returning no files, and a call
returning only nonallowed files has to be treated the same.
But im to dumb to see the logic in treating both as errors instead of "no files
matched", especially because that breaks existing code.
And treating it as "no files matched" doesnt break anything.
Please enlighten me if im wrong, and ill put on my pointy hat and sit in the
corner for the rest of the day.
But now i have link i can give the users telling me my servers doesn't work
right. So i guess i can live with that.

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
The function is documented to return FALSE on error. There is no problem
here...

Description:
------------
glob() cant be used directly in foreach when open_basedir is set.
i found #41655 which is about the change causing this, and a few other closed
tickets with "not a bug" as answer.
But that change destroys foreach(glob("nonexistent*") as ... when using
open_basedir, and the following comment in dir.c states that should be usable.
/* Some glob implementation simply return no data if no matches
were found, others return the GLOB_NOMATCH error code.
We don't want to treat GLOB_NOMATCH as an error condition
so that PHP glob() behaves the same on both types of
implementations and so that 'foreach (glob() as ...'
can be used for simple glob() calls without further error
checking.
*/
As far as i can tell the right thing to do would be to return an empty array
both when using glob("/etc/hosts") and glob("/etc/nonexistent") when
open_basedir is used. Or what am i missing?
Ive been using the following patch, and as far as i can tell its not possible
to check if a file exists when open_basedir is used, and
foreach(glob("nonext*")) works correctly.

Reproduce code:
---------------
set open_basedir /documentroot
open /documentroot/test.php with the following content
<? var_dump(glob("nonexistent*")); ?>
Expected result:
----------------
array(0) {
}
Actual result:
--------------
bool(false)
