* Include outlier status in `str(event)` for V2/V3 events (#10879)Richard van der Hoff2021-09-221-22/+12
| | | | | | | | | | | | | | | | | | | | | I meant to do this before, in #10591, but because I'm stupid I forgot to do it for V2 and V3 events. I've factored the common code out to `EventBase` to save us having two copies of it. This means that for `FrozenEvent` we replace `self.get("event_id", None)` with `self.event_id`, which I think is safe. `get()` is an alias for `self._dict.get()`, whereas `event_id()` is an `@property` method which looks up `self._event_id`, which is populated during construction from the same dict. We don't seem to rely on the fallback, because if the `event_id` key is absent from the dict then construction of the `EventBase` object will fail. Long story short, the only way this could change behaviour is if `event_dict["event_id"]` is changed *after* the `EventBase` object is constructed without updating the `_event_id` field, or vice versa - either of which would be very problematic anyway and the behavior of `str(event)` is the least of our worries.
* Clean up some logging in the federation event handler (#10591)Richard van der Hoff2021-08-161-1/+2
| | | | | | | | | | | | | | | | | | | * Include outlier status in `str(event)` In places where we log event objects, knowing whether or not you're dealing with an outlier is super useful. * Remove duplicated logging in get_missing_events When we process events received from get_missing_events, we log them twice (once in `_get_missing_events_for_pdu`, and once in `on_receive_pdu`). Reduce the duplication by removing the logging in `on_receive_pdu`, and ensuring the call sites do sensible logging. * log in `on_receive_pdu` when we already have the event * Log which prev_events we are missing * changelog
* Do not include signatures/hashes in make_{join,leave,knock} responses. (#10404)Patrick Cloke2021-07-161-0/+14
| | | | These signatures would end up invalid since the joining/leaving/knocking server would modify the response before calling send_{join,leave,knock}.

| | | | | | | Part of #9744 Removes all redundant `# -*- coding: utf-8 -*-` lines from files, as python 3 automatically reads source code as utf-8 now. `Signed-off-by: Jonathan de Jong <jonathan@automatia.nl>`

* Prep work for removing `outlier` from `internal_metadata` (#9411)Richard van der Hoff2021-03-171-3/+6
| | | | | | | | | | | | * Populate `internal_metadata.outlier` based on `events` table Rather than relying on `outlier` being in the `internal_metadata` column, populate it based on the `events.outlier` column. * Move `outlier` out of InternalMetadata._dict Ultimately, this will allow us to stop writing it to the database. For now, we have to grandfather it back in so as to maintain compatibility with older versions of Synapse.
* Remote dependency on distutils (#9125)Richard van der Hoff2021-01-151-1/+2
| | | | | | | | | `distutils` is pretty much deprecated these days, and replaced with `setuptools`. It's also annoying because it's you can't `pip install` it, and it's hard to figure out which debian package we should depend on to make sure it's there. Since we only use it for a tiny function anyway, let's just vendor said function into our codebase.
* Use `%r` rather than `%s` for stringifying events (#8679)Richard van der Hoff2020-10-291-2/+2
| | | | otherwise non-state events get written as `<FrozenEvent ... state_key='None'>` which is indistinguishable from state events with the actual state_key `None`.

* Remove stream ordering from Metadata dict (#8452)Richard van der Hoff2020-10-051-2/+4
| | | | | | | | There's no need for it to be in the dict as well as the events table. Instead, we store it in a separate attribute in the EventInternalMetadata object, and populate that on load. This means that we can rely on it being correctly populated for any event which has been persited to the database.

* Be more tolerant of membership events in unknown rooms (#8110)Richard van der Hoff2020-08-201-0/+2
| | | | It turns out that not all out-of-band membership events are labelled as such, so we need to be more accepting here.
* Replace iteritems/itervalues/iterkeys with native versions. (#7692)Patrick Cloke2020-06-151-3/+1
|
* Store room_versions in EventBase objects (#6875)Richard van der Hoff2020-03-051-14/+39
| | | | | | | This is a bit fiddly because it all has to be done on one fell swoop: * Wherever we create a new event, pass in the room version (and check it matches the format version) * When we prune an event, use the room version of the unpruned event to create the pruned version. * When we pass an event over the replication protocol, pass the room version over alongside it, and use it when deserialising the event again.
* Rewrite _EventInternalMetadata to back it with a _dictRichard van der Hoff2020-02-141-16/+39
| | | | Mostly, this gives mypy an easier time.
* Replace _event_dict_property with DictPropertyRichard van der Hoff2020-02-141-65/+79
| | | | | this amounts to the same thing, but replaces `_event_dict` with `_dict`, and removes some of the function layers generated by `property`.
* Add a `make_event_from_dict` method (#6858)Richard van der Hoff2020-02-071-2/+14
| | | | | | | ... and use it in places where it's trivial to do so. This will make it easier to pass room versions into the FrozenEvent constructors.

* Make 'event.redacts' never raise. (#6771)Erik Johnston2020-01-231-4/+24
| | | | | | There are quite a few places that we assume that a redaction event has a corresponding `redacts` key, which is not always the case. So lets cheekily make it so that event.redacts just returns None instead.
* Remove the ability to query relations when the original event was redacted. ↵Andrew Morgan2019-07-181-0/+11

| | | | | | | Adds new config option `cleanup_extremities_with_dummy_events` which periodically sends dummy events to rooms with more than 10 extremities. THIS IS REALLY EXPERIMENTAL.
* Fix error handling for rooms whose versions are unknown. (#5219)Richard van der Hoff2019-05-211-2/+6
| | | | | | | If we remove support for a particular room version, we should behave more gracefully. This should make client requests fail with a 400 rather than a 500, and will ignore individiual PDUs in a federation transaction, rather than the whole transaction.

* Make `prev_state` field optionalErik Johnston2019-03-081-1/+0

|/ | | | | | | | | | | | | | Currently we only have the one event format version defined, but this adds the necessary infrastructure to persist and fetch the format versions alongside the events. We specify the format version rather than the room version as: 1. We don't necessarily know the room version, existing events may be either v1 or v2. 2. We'd need to be careful to prevent/handle correctly if different events in the same room reported to be of different versions, which sounds annoying.

* Fix handling of redacted events from federationErik Johnston2018-09-131-0/+5
| | | | | | | | | | If we receive an event that doesn't pass their content hash check (e.g. due to already being redacted) then we hit a bug which causes an exception to be raised, which then promplty stops the event (and request) from being processed. This effects all sorts of federation APIs, including joining rooms with a redacted state event.

| | | | | | | | | | | | | They raised KeyError before. I'm changing this because the code uses hasattr() to check for the presence of a key. This worked accidentally before, because hasattr() silences all exceptions in python 2. However, in python3, this isn't the case anymore. I had a look around to see if anything depended on this raising a KeyError and I couldn't find anything. Of course, I could have simply missed it. Signed-off-by: Adrian Tschira <nota@notafile.com>
