Unfortunately, I was exaggerating, when I said “task scheduler”. What I really have right now is just a FIFO worker that handles a long-running task for a custom local tool. I want to start small and build up, rather than trying to design something that will meet every use case. But I have contributed my thoughts to https://bugs.koha-community.org/bugzilla3//show_bug.cgi?id=22417 <https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=22417> . And actually I would really like to collaborate with you, Tomas, on creating functionality that would make Koha Plugins first class citizens for background tasks, as I think that will actually help us focus on the message queue and task scheduling systems rather than the tasks themselves.

I’m creating a service for a RabbitMQ-based task scheduler and my unit file is 17 declarative configuration lines. Creating a koha-mq-scheduler file looks like it’ll be hundreds of lines of shell script code. My unit file is actually a “template” file, which means I have 1 file in /etc/systemd/system/koha-mq-scheduler@.service <mailto:/etc/systemd/system/koha-mq-scheduler@.service> and I can just invoke “systemctl start koha-mq-scheduler@INSTANCE.service <mailto:koha-mq-scheduler@INSTANCE.service> ” to start the service. You can use the %i placeholder in the unit file and it will be replaced with INSTANCE, so you can set paths, environmental variables, et cetera very easily. It’s so easy and convenient. I think all modern Linux OSes use systemd for their init system, so I think it would be pretty safe to use. I’m happy to work on this one, but I guess I’d like to see if other people have interest in this.
