Cache invalidation for scheduled Entries

[ostark]

Problem: Scheduled Entries do not purge the cache automatically.

Idea

A console command keeps an eye on entries.postDate and entries. expiryDate. This command must be scheduled via cron to invalidated the cache without human interaction.

We just discussed this on the Craft Slack.

For Craft 2 I did this plugin.
For Craft 3, I think i'm going to port it and convert it into using delayed jobs instead.

Perfect! @sjelfull

So I’ve been thinking about this too, for Craft 2 I did a wider agnostic approach with Scheduler that does this but can also be extended to do anything else, like email someone a reminder in a week or whatever.

[joshangell]

The conceptual issue I’m having with delayed jobs in a queue is that what if the server gets rebooted or whatever, do they stay around? Can they be scheduled for a long time is the future, like a month or whatever?

I appreciated you could use SQS or whatever, but there’s something nice and safe about a row in a db.

@joshangell thanks for your input.
@sjelfull I'm not sure if delayed jobs are appropriate for this as you never get Jobs out of a queue, e.g. in case the editor decides to change the expire or publish date. Maybe this is not a big issue.

[sjelfull]

@ostark Doesn't matter. You just publish a new job, and in the service you check if the entry is published/expired.

Ok, @sjelfull, I'm happy to depend on your plugin 👍
Do you know if plugin-plugin dependencies are possible with Craft 3 anyways?

[sjelfull]

Craft does not support it directly, but you can suggest/require your own dependencies, and they will be installed by composer.

I just found this, and it seems to solve a problem I've been having. I see it's been merged into develop. Any change of getting it into a minor release in the near future?

Or I guess an Upper 2 release.

[ostark]

2.0 is a completely different code base. It's better than the 1.0 code, but also not completely happy - it's actually 2 years old.
I'm looking forward to bring Upper to the next level this year.
