These objects represent from 30 to 70% of the rows on the objects table,
based on numbers from a few live instances (single-user, small, large.)
As those pseudo-objects prevent creating objects with those actual IDs,
deleting them is a better solution. This could have happened if an
object used another object's ID as its context.
This field replaces the now deprecated conversation_id field, and now
exposes the ActivityPub object `context` directly via the MastoAPI
instead of relying on StatusNet-era data concepts.
This field seems to be a left-over from the StatusNet era.
If your application uses `pleroma.conversation_id`: this field is
deprecated.
It is currently stubbed instead by doing a CRC32 of the context, and
clearing the MSB to avoid overflow exceptions with signed integers on
the different clients using this field (Java/Kotlin code, mostly; see
Husky and probably other mobile clients.)
This should be removed in a future version of Pleroma. Pleroma-FE
currently depends on this field, as well.
30 to 70% of the objects in the object table are simple JSON objects
containing a single field, 'id', being the context's ID. The reason for
the creation of an object per context seems to be an old relic from the
StatusNet era, and has only been used nowadays as an helper for threads
in Pleroma-FE via the `pleroma.conversation_id` field in status views.
An object per context was created, and its numerical ID (table column)
was used and stored as 'context_id' in the object and activity along
with the full 'context' URI/string.
This commit removes this field and stops creation of objects for each
context, which will also allow incoming activities to use activity IDs
as contexts, something which was not possible before, or would have been
very broken under most circumstances.
The `pleroma.conversation_id` field has been reimplemented in a way to
maintain backwards-compatibility by calculating a CRC32 of the full
context URI/string in the object, instead of relying on the row ID for
the created context object.
Moderators were able to delete statusses via pleroma-fe. For that reason I now gave them :messages_delete by default.
They are also able to recieve reports through the notifications. For that reason I now gave them :reports_manage_reports by default.
They were also able to see deactivated accounts through pleroma-fe. However
* they were unable to tell if the account is deactivated or not (which was a bug and fixed by thes privileges MR this commit is part of)
* they were not able to actually change the activation state.
Because of this, I decided to *not* give them the privilege :users_manage_activation_state as this would give significantly more
privileges, while not giving it will actually improve the current experience as it works around the existing bug of not showing activation state.
