#32622 [Com]: IMAP toolkit crash

ID: 32622 Comment by: slim at inbox dot lv Reported By: lst_hoe01 at kwsoft dot de Status: No Feedback Bug Type: IMAP related Operating System: Linux Kernel 2.4.21 PHP Version: 4.3.11 New Comment: this problem appears on latest 5.2.x branch as well. in my case the problem happens when php script exceed "Maximum execution time" on imap_fetch_overview() function running on a message. Next time trying to access the message php crashes with "IMAP toolkit crash: Lock when already locked" script to reproduce: ============================================== $mbox = imap_open($server, $user, $pass); $overview = imap_fetch_overview($mbox,$msgid); $headers = imap_fetchheader($mbox,$msgid); print "ended"; imap_close($mbox); ============================================== set max_execution_time = 1 and try to open message where "Reply-To:" or any other header repeats ~20000 times. Looks like c-client does not unlock mailbox until imap_fetch_overview() complete even php script already exited Previous Comments: ------------------------------------------------------------------------ [2005-04-20 01:00:10] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically. If you are able to provide the information that was originally requested, please do so and change the status of the bug back to "Open". ------------------------------------------------------------------------ [2005-04-12 02:51:18] iliaa@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2005-04-07 12:32:14] lst_hoe01 at kwsoft dot de Description: ------------ With HORDE/IMP in some situations (long delay connect) the error "IMAP toolkit crash: Lock when already locked" is logged by PHP. According to the maintainer of the IMAP toolkit this is a invalid use of the toolkit (Quoting) : > The "Lock when already locked" error message indicates a > software bug which is supposedly impossible in UW imapd. It > has nothing to do with file locking; instead, it indicates a > forbidden recursive call into the c-client library from a > c-client callback in the application. Thanxs for any help Andreas Reproduce code: --------------- IMP-Application...
