In trying to use the MSC3026 busy presence status, the user's status
would be set back to 'online' next time they synced. This change makes
it so that syncing does not affect a user's presence status if it
is currently set to 'busy': it must be removed through the presence
API.
The MSC defers to implementations on the behaviour of busy presence,
so this ought to remain compatible with the MSC.
There are a bunch of places we call get_success on an immediate value, which is unnecessary. Let's rip them out, and remove the redundant functionality in get_success and friends.
It seems like calling `_get_state_group_for_events` for an event where the
state is unknown is an error. Accordingly, let's raise an exception rather than
silently returning an empty result.
If we're missing most of the events in the room state, then we may as well call the /state endpoint, instead of individually requesting each and every event.
This field is only to be used in the Server-Server API, and not the
Client-Server API, but was being leaked when a federation response
was used in the /hierarchy API.
...and various code supporting it.
The /spaces endpoint was from an old version of MSC2946 and included
both a Client-Server and Server-Server API. Note that the unstable
/hierarchy endpoint (from the final version of MSC2946) is not yet
removed.
Part of the Tchap Synapse mainlining.
This allows modules to implement extra logic to figure out whether a given 3PID can be added to the local homeserver. In the Tchap use case, this will allow a Synapse module to interface with the custom endpoint /internal_info.
Only allow files which file size and content types match configured
limits to be set as avatar.
Most of the inspiration from the non-test code comes from matrix-org/synapse-dinsic#19
This is in the context of mainlining the Tchap fork of Synapse. Currently in Tchap usernames are derived from the user's email address (extracted from the UIA results, more specifically the m.login.email.identity step).
This change also exports the check_username method from the registration handler as part of the module API, so that a module can check if the username it's trying to generate is correct and doesn't conflict with an existing one, and fallback gracefully if not.

By returning all of the m.space.child state of the space, not just
the first 50. The number of rooms returned is still capped at 50.
For the federation API this implies that the requesting server will
need to individually query for any other rooms it is not joined to.
* `_auth_and_persist_outliers`: mark persisted events as outliers
Mark any events that get persisted via `_auth_and_persist_outliers` as, well,
outliers.
Currently this will be a no-op as everything will already be flagged as an
outlier, but I'm going to change that.
* `process_remote_join`: stop flagging as outlier
The events are now flagged as outliers later on, by `_auth_and_persist_outliers`.
* `send_join`: remove `outlier=True`
The events created here are returned in the result of `send_join` to
`FederationHandler.do_invite_join`. From there they are passed into
`FederationEventHandler.process_remote_join`, which passes them to
`_auth_and_persist_outliers`... which sets the `outlier` flag.
* `get_event_auth`: remove `outlier=True`
stop flagging the events returned by `get_event_auth` as outliers. This method
is only called by `_get_remote_auth_chain_for_event`, which passes the results
into `_auth_and_persist_outliers`, which will flag them as outliers.
* `_get_remote_auth_chain_for_event`: remove `outlier=True`
we pass all the events into `_auth_and_persist_outliers`, which will now flag
the events as outliers.
* `_check_sigs_and_hash_and_fetch`: remove unused `outlier` parameter
This param is now never set to True, so we can remove it.
* `_check_sigs_and_hash_and_fetch_one`: remove unused `outlier` param
This is no longer set anywhere, so we can remove it.
* `get_pdu`: remove unused `outlier` parameter
... and chase it down into `get_pdu_from_destination_raw`.
* `event_from_pdu_json`: remove redundant `outlier` param
This is never set to `True`, so can be removed.
* changelog
* update docstring
If `room_list_publication_rules` was configured with a rule with a
non-wildcard alias and a room was created with an alias then an
internal server error would have been thrown.
This fixes the error and properly applies the publication rules
during room creation.

* We only need to fetch users in private rooms
* Filter out `user_id` at the top
* Discard excluded users in the top loop
We weren't doing this in the "First, if they're our user" branch so this
is a bugfix.
* The caller must check that `user_id` is included
This is in the docstring. There are two call sites:
- one in `_handle_room_publicity_change`, which explicitly checks before calling;
- and another in `_handle_room_membership_event`, which returns early if
the user is excluded.
So this change is safe.

Found while working on the Gitter backfill script and noticed
it only happened after we sent 7 batches, https://gitlab.com/gitterHQ/webapp/-/merge_requests/2229#note_665906390
When there are more than 5 backward extremities for a given depth,
backfill will throw an error because we sliced the extremity list
to 5 but then try to iterate over the full list. This causes
us to look for state that we never fetched and we get a `KeyError`.
Before when calling `/messages` when there are more than 5 backward extremities:

The following scenarios would halt the user directory updater:
- user joins room
- user leaves room
- user present in room which switches from private to public, or vice versa.
for two classes of users:
- appservice senders
- users missing from the user table.
If this happened, the user directory would be stuck, unable to make forward progress.
Exclude both cases from the user directory, so that we ignore them.

This splits apart `handle_new_user` into a function which adds an entry to the `user_directory` and a function which updates the room sharing tables. I plan to continue doing more of this kind of refactoring to clarify the implementation.
Fix a long-standing bug where a batch of user directory changes would be
silently dropped if the server left a room early in the batch.

* Introduce `should_include_local_users_in_dir`
We exclude three kinds of local users from the user_directory tables. At
present we don't consistently exclude all three in the same places. This
commit introduces a new function to gather those exclusion conditions
together. Because we have to handle local and remote users in different
ways, I've made that function only consider the case of remote users.
It's the caller's responsibility to make the local versus remote
distinction clear and correct.
A test fixup is required. The test now hits a path which makes db
queries against the users table. The expected rows were missing, because
we were using a dummy user that hadn't actually been registered.
We also add new test cases to covert the exclusion logic.
----
By my reading this makes these changes:
* When an app service user registers or changes their profile, they will
_not_ be added to the user directory. (Previously only support and
deactivated users were excluded). This is consistent with the logic that
rebuilds the user directory. See also [the discussion
here](https://github.com/matrix-org/synapse/pull/10914#discussion_r716859548).
* When rebuilding the directory, exclude support and disabled users from
room sharing tables. Previously only appservice users were excluded.
* Exclude all three categories of local users when rebuilding the
directory. Previously `_populate_user_directory_process_users` didn't do
any exclusion.

* Pull out GetUserDirectoryTables helper
* Don't rebuild the dir in tests that don't need it

This means we don't have to force a directory regbuild in to tests of
the user directory search.

* Factor more stuff out of `_get_events_and_persist`
It turns out that the event-sorting algorithm in `_get_events_and_persist` is
also useful in other circumstances. Here we move the current
`_auth_and_persist_fetched_events` to `_auth_and_persist_fetched_events_inner`,
and then factor the sorting part out to `_auth_and_persist_fetched_events`.
* `_get_remote_auth_chain_for_event`: remove redundant `outlier` assignment
`get_event_auth` returns events with the outlier flag already set, so this is
redundant (though we need to update a test where `get_event_auth` is mocked).
* `_get_remote_auth_chain_for_event`: move existing-event tests earlier
Move a couple of tests outside the loop. This is a bit inefficient for now, but
a future commit will make it better. It should be functionally identical.
* `_get_remote_auth_chain_for_event`: use `_auth_and_persist_fetched_events`
We can use the same codepath for persisting the events fetched as part of an
auth chain as for those fetched individually by `_get_events_and_persist` for
building the state at a backwards extremity.
* `_get_remote_auth_chain_for_event`: use a dict for efficiency
`_auth_and_persist_fetched_events` sorts the events itself, so we no longer
need to care about maintaining the ordering from `get_event_auth` (and no
longer need to sort by depth in `get_event_auth`).
That means that we can use a map, making it easier to filter out events we
already have, etc.
* changelog
* `_auth_and_persist_fetched_events`: improve docstring
* Improve typing in user_directory files
This makes the user_directory.py in storage pass most of mypy's
checks (including `no-untyped-defs`). Unfortunately that file is in the
tangled web of Store class inheritance so doesn't pass mypy at the moment.
The handlers directory has already been mypyed.

It's a simplification, but one that'll help make the user directory logic easier
to follow with the other changes upcoming. It's not strictly required for those
changes, but this will help simplify the resulting logic that listens for
`m.room.member` events and generally make the logic easier to follow.
This means the config option `search_all_users` ends up controlling the
search query only, and not the data we store. The cost of doing so is an
extra row in the `user_directory` and `user_directory_search` tables for
each local user which
- belongs to no public rooms
- belongs to no private rooms of size ≥ 2
I think the cost of this will be marginal (since they'll already have entries
in `users` and `profiles` anyway).
As a small upside, a homeserver whose directory was built with this
change can toggle `search_all_users` without having to rebuild their
directory.

This updates the ordering of the returned events from the spaces
summary API to that defined in MSC2946 (which updates MSC1772).
Previously a step was skipped causing ordering to be inconsistent with
clients.
Turns out that the functionality added in #10546 to skip TLS was incompatible
with older Twisted versions, so we need to be a bit more inventive.
Also, add a test to (hopefully) not break this in future. Sadly, testing TLS is
really hard.
As opposed to only allowing the summary of spaces which the user is
already in or has world-readable visibility.
This makes the logic consistent with whether a space/room is returned
as part of a space and whether a space summary can start at a space.
If a room which the requesting user was invited to was queried over
federation it will now properly appear in the spaces summary (instead
of being stripped out by the requesting server).
If there are no services providing a protocol, omit it completely
instead of returning an empty dictionary.
This fixes a long-standing spec compliance bug.
Reproducible on a federated homeserver when there is a membership auth event as a floating outlier. Then when we try to backfill one of that persons messages, it has missing membership auth to fetch which caused us to mistakenly replace the `context` for the message with that of the floating membership `outlier` event. Since `outliers` have no `state` or `state_group`, the error bubbles up when we continue down the persisting route: `sqlite3.IntegrityError: NOT NULL constraint failed: event_to_state_groups.state_group`
Call stack:
```
backfill
_auth_and_persist_event
_check_event_auth
_update_auth_events_and_context_for_auth
```
