Bug #49132 posix_times returns false without error
Submitted: 2009-08-01 17:42 UTC Modified: 2009-08-01 18:22 UTC
From: phpbugs at gunnu dot us Assigned:
Status: Closed Package: POSIX related
PHP Version: 6SVN-2009-08-01 (SVN) OS: Linux 2.6
Private report: No CVE-ID:
 [2009-08-01 17:42 UTC] phpbugs at gunnu dot us
Description:
------------
/[cvs]/php-src/ext/posix/posix.c rev 1.110 line 687 detects error if 'ticks' is a negative value. POSIX.1 states -1 is an error condition, but other negative values are acceptable overflow, which can be caused by a long uptime.
posix_times() returns false under these conditions when there is no error except a long uptime.

Reproduce code:
---------------
<?php
var_dump( posix_times() ); //returns false if uptime is high enough without setting error
?>

Expected result:
----------------
A populated array

Actual result:
--------------
bool(FALSE)
