This is based on me setting one up, but I kept it general with mostly linking to other documentation.
The idea is that to just provide some Pleroma-specific info, maybe give some pointers, and point to the right (external) docs.
It used a timer to sleep.
But time also goes on when doing other things, so depending on hardware, the timings could be off.
I slightly changed the tests so we still test what we functionally want.
Instead of waiting until the cache expires I now have a function to expire the test and use that.
That means we're not testing any more if the cache really expires after a certain amount of time,
but that's the responsability of the dependency imo, so shouldn't be a problem.
I also changed `Pleroma.Web.Endpoint, :http, :ip` to `127.0.0.1` because that's the setting people typically have,
and I see no reason to do it differently.
Especially since it's an exernal ip, which may come over as weird or suspicious to people.
It is possible for an earlier Update to be received by us later.
For this, we now
(1) only allows Updates to poll counts if there is no updated field,
or the updated field is the same as the last updated date or
creation date;
(2) does not allow updating anything if the updated field
is older than the last updated date or creation date;
(3) allows updating updatable fields otherwise (normal updates);
(4) if only the updated field is changed, it does not create
a new history item on its own.
In Create validator we do not validate the object data,
but that is because the object itself will go through the
pipeline again, which is not the case for Update. Thus,
we added validation for objects in Update activities.
The previous pictures were labeled as public domain, but are actually a collage of pictures under other licenses.
I now replaced them with a jpeg of simply a white pixel.
I used keyword_list[:key], but if the key doesn't exist, it will return nil. I actually expect a list and further down the code I use that list.
I believe the key should always be present, but in case it's not, it's better to return an empty list instead of nil. That way the code wont fail further down the line.
