Since #2849 there is no limit for the current state we fetch to
calculate history visibility. In large rooms this can cause us to fetch
thousands of membership events we don't really care about.
This now only gets the state event types and senders in our timeline,
which should significantly reduce the amount of events we fetch from the
database.
Also removes `MaxTopologicalPosition`, as it is an unnecessary DB call,
given we use the result in `topological_position < $1` calls.
* syncapi: add more tests; fix more bugs
bugfixes:
- The postgres impl of TopologyTable.SelectEventIDsInRange did not use the provided txn
- The postgres impl of EventsTable.SelectEvents did not preserve the ordering of the input event IDs in the output events slice
- The sqlite impl of EventsTable.SelectEvents did not use a bulk `IN ($1)` query.
Added tests:
- `TestGetEventsInRangeWithTopologyToken`
- `TestOutputRoomEventsTable`
- `TestTopologyTable`
* -p 1 for now
* Convert stream positions into topological positions for both `from` and `to` in `/messages`
* Hopefully it works now
* Remove unnecessary logging
* Return sane values if `StreamToTopologicalPosition` can't work out the right thing to do
* Revert logging change
* tweaks
* Fix `selectEventIDsInRangeASCSQL`
* Test `Getting messages going forward is limited for a departed room (SPEC-216)` was passing incorrectly so un-whitelist it
* SendEventWithState events as new
* Use cumulative state IDs for final event
* Error wrapping in calculateAndSetState
* Handle overwriting same event type and state key
* Hacky way to spot historical events
* Don't exclude from sync
* Don't generate output events when rewriting forward extremities
* Update output event check
* Historical output events
* Define output room event type
* Notify key changes on state
* Don't send our membership event twice
* Deduplicate state entries
* Tweaks
* Remove unnecessary nolint
* Fix current state upsert in sync API

* Sync API don't consume state events
* Process events actually
* Improve outlier check
* Fix local room check
* Remove extra room check, it seems to break the whole damn world
* Fix federated join check
* Fix nil pointer exception
* Better comments on DeduplicateStateEntries
* Reflow forced federated joins
* Don't force federated join for possibly even local invites
* Comment SendEventWithState better
* Rewrite room state in sync API storage
* Add TODO
* Clean up all room data when receiving create event
* Don't generate output events for rewrites, but instead notify that state is rewritten on the final new event
* Rename to PurgeRoom
* Exclude backfilled messages from /sync
* Split out rewriting state from updating state from state res

* Refactor all postgres tables; start work on sqlite
* wip sqlite merges; database is locked errors to investigate and failing tests
* Revert "wip sqlite merges; database is locked errors to investigate and failing tests"
This reverts commit 26cbfc5b75.
* convert current room state table
* port over sqlite topology table
* remove a few functions
* remove more functions
* Share more code
* factor out completesync and a bit more
* Remove remaining code
* Correctly generate backpagination tokens for events which have the same depth
With tests. Unfortunately the code around here is hard to understand.
There will be a subsequent PR which fixes this up now that we have a test
harness in place.
* Add postgres impl
* More linting
* Fix psql statement so it actually works
* Use HeaderedEvent in syncapi
* Update notifier test
* Fix persisting headered event
* Clean up unused API function
* Fix overshadowed err from linter
* Write headered JSON to invites table too
* Rename event_json to headered_event_json in syncapi database schemae
* Fix invites_table queries
* Update QueryRoomVersionCapabilitiesResponse comment
* Fix syncapi SQLite
* Always defer *sql.Rows.Close and consult with Err
database/sql.Rows.Next() makes sure to call Close only after exhausting
result rows which would NOT happen when returning early from a bad Scan.
Close being idempotent makes it a great candidate to get always deferred
regardless of what happens later on the result set.
This change also makes sure call Err() after exhausting Next() and
propagate non-nil results from it as the documentation advises.
Closes#764
