Clear target server cache option

[hughbris]

I had a crazy idea when I should have been sleeping that it would be handy to be able to perform a clear cache operation on the target publishing server when pushing, e.g. large image updates.

That came out of a fear that when a client of mine makes a large set of edits to be pushed at once, users of the site might see some screwy pages until the cache refreshes. I have witnessed this myself updating media via git on command line. I normally have high levels of caching set for production servers.

You could do this by triggering another webhook on the editing instance. It could be a global checkbox on the file selection list UI.

This idea is not very incompatible with another half-baked plan of mine to split this plugin into "pushy-publisher" and "pushy-target".

Do you think the person who is supposed to publish the changes is apt to decide whether a clear cache is needed?

• Does the user know the size of the push?
• Does the user know when the issue might occur?
• Does the user know the performance hiccup of clear cache on a large site?

You're right, those are serious concerns. This came about because I am expecting a client to push some big changes including media onto the production server. Probably not gonna happen often, I might try to coordinate a cache refresh from me.

Some thoughts:

• When a copy/paste of a /user folder (maybe excluding plugins/themes) on the same server is faster then a remote fetch (the git changes), it might be an idea to apply the git changes onto a staging folder (no need to be a website) and copy/paste that folder into the production Grav folder.
• Or only apply scheduled pulls on remote server during hours that user traffic is low.
• Or maybe even both above options

The new Scheduler Webhook plugin made possible after Grav 1.7.49 is probably just the tool to accomplish this, although @pamtbaau's user concerns still apply.
