Bug description:Script hangs after max_execution_time (tzset)
Description:
------------
As tzset functions is not async-signal-safe, nor safe to be longjmp'ed out,
If a timeout occurs during soem glib call, with a lock set, the PHP script
will hangs.
tzset should not be called during timeout management.
Attached patch solves this.
Test script:
---------------
<?php
ini_set('max_execution_time', '1');
echo "Playing with env. and tzset";
$tabs = timezone_identifiers_list();
while (true) {
foreach ($tabs as $tab) {
putenv("TZ=$tab");
}
echo ".";
}
Must be run various time to reproduce
Expected result:
----------------
Script output "PHP Fatal error: Maximum execution time of 1 second
exceeded in..." and exit.
Actual result:
--------------
Script hangs after "PHP Fatal error: Maximum execution time of 1 second
exceeded in..."
