These tests relied on the removed Fetcher.fetch_object_from_id!/2 function injecting the error tuple into a log message with the exact words "Object containment failed."
We will keep this behavior by generating a similar log message, but perhaps this should do a better job of matching on the error tuple returned by Transmogrifier.handle_incoming/1
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.
Current FedSocket implementation has a bunch of problems. It doesn't
have proper error handling (in case of an error the server just doesn't
respond until the connection is closed, while the client doesn't match
any error messages and just assumes there has been an error after 15s)
and the code is full of bad descisions (see: fetch registry which uses
uuids for no reason and waits for a response by recursively querying a
ets table until the value changes, or double JSON encoding).
Sometime ago I almost completed rewriting fedsockets from scrach to
adress these issues. However, while doing so, I realized that fedsockets
are just too overkill for what they were trying to accomplish, which is
reduce the overhead of federation by not signing every message.
This could be done without reimplementing failure states and endpoint
logic we already have with HTTP by, for example, using TLS cert auth,
or switching to a more performant signature algorithm. I opened
https://git.pleroma.social/pleroma/pleroma/-/issues/2262 for further
discussion on alternatives to fedsockets.
From discussions I had with other Pleroma developers it seems like they
would approve the descision to remove them as well,
therefore I am submitting this patch.
Validate the content-type of the response when fetching an object,
according to https://www.w3.org/TR/activitypub/#x3-2-retrieving-objects.
content-type headers had to be added to many mocks in order to support
this, some of this was done with a regex. While I did go over the
resulting files to check I didn't modify anything unrelated, there is a
possibility I missed something.
Closes pleroma#1948
