--- Comment #10 from Alex Buckley <alexbuck...@catalyst.net.nz> --- Created attachment 78582 --> https://bugs.koha-community.org/bugzilla3/attachment.cgi?id=78582&action=edit Bug 15529 - Locking process_message_queue.pl cron whilst it is running This amended patch is called by koha-common. koha-common runs this process_message_queue.pl cronjob foreach enabled Koha instance on the server. As this cronjob is run for every Koha instance the retrival of all Koha instance names from debian/scripts/koha-scripts in previous obsolete patches on this bug report and the looping through every name to check if the lock file existed is redundant. Instead this patch retrieves the 'logdir' of the Koha instance being iterated over and checks if the messagequeue.lock file in that directory is locked. If the aforementioned file is not locked then the SendQueuedMessages() in C4/Letters.pm is called, otherwise an email is sent (to the manually inputted email server, and to/from addresses) and duplicate execution of the cronjob is prevented. Test plan: 1. In two terminals open koha-shell and try to run ./process_message_queue.pl and notice you can run the script multiple times simulataneously without a warning/error being displayed 2. Apply patch and input the email server, to/from email addresses you would like the email to be sent to. Also confirm your Koha instance is enabled to send emails. 3. Repeat step 1 and notice that the second of the two scripts to be run will output text saying './process_message_queue.pl is already running. Exiting' In this case the aforementioned text is displayed and the body of the cronjob is not run. 4. The first cronjob script to run, runs without issues 5. At the end of the execution of the first script a 15 second pause is run 6.
