Enabling the plugin in OJS 3 does not set up scheduled tasks

[ubermichael]

I cloned the plugin to an OJS 3 instance in plugins/generic/pln. I enabled it and got the terms of use and agreed to them. But the plugin didn't set up a task in the scheduled_tasks table like it would have in OJS 2. As a result, none of the scheduled tasks are firing automatically either via acron or via system cron.

OJS 3.1.1.1 release (not from git) PHP 5.6.36 MySQL Ver 14.14 Distrib 5.7.22, for osx10.11 (x86_64) OS X 10.11 Apache 2.4.28

I'm happy to help debug this, but I don't know enough about OJS 3 or the task system to fix it.

Hi @ubermichael! Thanks for bringing that up. You are right, indeed enabling the plugin does not add the Depositor class to the scheduled_tasks table, even though the code seems to register the appropriate hook. I will check the reason for that.

In any case, if you run the Acron's plugin reload scheduled tasks function from the Plugin's table, then the Depositor task is added successfully.

It seems that this behavior is indented. There is that issue https://github.com/pkp/pkp-lib/issues/2550 which may alter that, but for now the way to go is to run the "Reload scheduled tasks" function of the AcronPlugin.

If you agree I will close this issue for now.

Well, if that's the official way to do things I guess we have no choice. But there will be a lot of journals that don't follow that step, even if the documentation or UI is updated with instructions like this.

[defstat]

@ubermichael yes I know. It seems to be the way for now though.

[mjordan]

Perhaps we should be requiring Acron as dependency for the PLN plugin?

[defstat]

Yes the Acron plugin should be enabled.

[mjordan]

OK, I'll specify that as a dependency in the testing instructions.
