- Always include `device_one_time_keys_count` key in `/sync` response to work around a bug in Element Android that broke encryption for new devices. ([\#10457](https://github.com/matrix-org/synapse/issues/10457))
Synapse 1.39.0rc1 (2021-07-20)
==============================
The Third-Party Event Rules module interface has been deprecated in favour of the generic module interface introduced in Synapse v1.37.0. Support for the old interface is planned to be removed in September 2021. See the [upgrade notes](https://matrix-org.github.io/synapse/latest/upgrade.html#upgrading-to-v1390) for more information.
Features
--------
- Add the ability to override the account validity feature with a module. ([\#9884](https://github.com/matrix-org/synapse/issues/9884))
- The spaces summary API now returns any joinable rooms, not only rooms which are world-readable. ([\#10298](https://github.com/matrix-org/synapse/issues/10298), [\#10305](https://github.com/matrix-org/synapse/issues/10305))
- Add a new version of the R30 phone-home metric, which removes a false impression of retention given by the old R30 metric. ([\#10332](https://github.com/matrix-org/synapse/issues/10332), [\#10427](https://github.com/matrix-org/synapse/issues/10427))
- Allow providing credentials to `http_proxy`. ([\#10360](https://github.com/matrix-org/synapse/issues/10360))
Bugfixes
--------
- Fix error while dropping locks on shutdown. Introduced in v1.38.0. ([\#10433](https://github.com/matrix-org/synapse/issues/10433))
- Add base starting insertion event when no chunk ID is specified in the historical batch send API. ([\#10250](https://github.com/matrix-org/synapse/issues/10250))
- Fix historical batch send endpoint (MSC2716) rejecting batches with messages from multiple senders. ([\#10276](https://github.com/matrix-org/synapse/issues/10276))
- Fix purging rooms that other homeservers are still sending events for. Contributed by @ilmari. ([\#10317](https://github.com/matrix-org/synapse/issues/10317))
- Fix errors during backfill caused by previously purged redaction events. Contributed by Andreas Rammhold (@andir). ([\#10343](https://github.com/matrix-org/synapse/issues/10343))
- Fix the user directory becoming broken (and noisy errors being logged) when knocking and room statistics are in use. ([\#10344](https://github.com/matrix-org/synapse/issues/10344))
- Fix newly added `synapse_federation_server_oldest_inbound_pdu_in_staging` prometheus metric to measure age rather than timestamp. ([\#10355](https://github.com/matrix-org/synapse/issues/10355))
- Fix PostgreSQL sometimes using table scans for queries against `state_groups_state` table, taking a long time and a large amount of IO. ([\#10359](https://github.com/matrix-org/synapse/issues/10359))
- Fix `make_room_admin` failing for users that have left a private room. ([\#10367](https://github.com/matrix-org/synapse/issues/10367))
- Fix a number of logged errors caused by remote servers being down. ([\#10400](https://github.com/matrix-org/synapse/issues/10400), [\#10414](https://github.com/matrix-org/synapse/issues/10414))
- Responses from `/make_{join,leave,knock}` no longer include signatures, which will turn out to be invalid after events are returned to `/send_{join,leave,knock}`. ([\#10404](https://github.com/matrix-org/synapse/issues/10404))
Improved Documentation
----------------------
- Updated installation dependencies for newer macOS versions and ARM Macs. Contributed by Luke Walsh. ([\#9971](https://github.com/matrix-org/synapse/issues/9971))

## Using logcontexts with Deferreds
## Using logcontexts with awaitables
Deferreds --- and in particular, `defer.inlineCallbacks` --- break the
linear flow of code so that there is no longer a single entry point
where we should set the logcontext and a single exit point where we
should remove it.
Awaitables break the linear flow of code so that there is no longer a single entry point
where we should set the logcontext and a single exit point where we should remove it.
Consider the example above, where `do_request_handling` needs to do some
blocking operation, and returns a deferred:
blocking operation, and returns an awaitable:
```python
@defer.inlineCallbacks
def handle_request(request_id):
async def handle_request(request_id):
with context.LoggingContext() as request_context:
request_context.request = request_id
yield do_request_handling()
await do_request_handling()
logger.debug("finished")
```
In the above flow:
- The logcontext is set
- `do_request_handling` is called, and returns a deferred
- `handle_request` yields the deferred
- The `inlineCallbacks` wrapper of `handle_request` returns a deferred
- `do_request_handling` is called, and returns an awaitable
- `handle_request` awaits the awaitable
- Execution of `handle_request` is suspended
So we have stopped processing the request (and will probably go on to
start processing the next), without clearing the logcontext.
To circumvent this problem, synapse code assumes that, wherever you have
a deferred, you will want to yield on it. To that end, whereever
functions return a deferred, we adopt the following conventions:
an awaitable, you will want to `await` it. To that end, whereever
functions return awaitables, we adopt the following conventions:
**Rules for functions returning deferreds:**
**Rules for functions returning awaitables:**
> - If the deferred is already complete, the function returns with the
> - If the awaitable is already complete, the function returns with the
> same logcontext it started with.
> - If the deferred is incomplete, the function clears the logcontext
> before returning; when the deferred completes, it restores the
> - If the awaitable is incomplete, the function clears the logcontext
> before returning; when the awaitable completes, it restores the
> logcontext before running any callbacks.
That sounds complicated, but actually it means a lot of code (including
the example above) "just works". There are two cases:
- If `do_request_handling` returns a completed deferred, then the
- If `do_request_handling` returns a completed awaitable, then the
logcontext will still be in place. In this case, execution will
continue immediately after the `yield`; the "finished" line will
continue immediately after the `await`; the "finished" line will
be logged against the right context, and the `with` block restores
the original context before we return to the caller.
- If the returned deferred is incomplete, `do_request_handling` clears
- If the returned awaitable is incomplete, `do_request_handling` clears
the logcontext before returning. The logcontext is therefore clear
when `handle_request` yields the deferred. At that point, the
`inlineCallbacks` wrapper adds a callback to the deferred, and
returns another (incomplete) deferred to the caller, and it is safe
to begin processing the next request.
when `handle_request` `await`s the awaitable.
Once `do_request_handling`'s deferred completes, it will reinstate
the logcontext, before running the callback added by the
`inlineCallbacks` wrapper. That callback runs the second half of
`handle_request`, so again the "finished" line will be logged
against the right context, and the `with` block restores the
original context.

The following sections describe pitfalls and helpful patterns when
implementing these rules.
Always yield your deferreds
---------------------------
Always await your awaitables
----------------------------
Whenever you get a deferred back from a function, you should `yield` on
it as soon as possible. (Returning it directly to your caller is ok too,
if you're not doing `inlineCallbacks`.) Do not pass go; do not do any
logging; do not call any other functions.
Whenever you get an awaitable back from a function, you should `await` on
it as soon as possible. Do not pass go; do not do any logging; do not
call any other functions.
```python
@defer.inlineCallbacks
def fun():
async def fun():
logger.debug("starting")
yield do_some_stuff() # just like this
await do_some_stuff() # just like this
d = more_stuff()
result = yield d # also fine, of course
coro = more_stuff()
result = await coro # also fine, of course
return result
def nonInlineCallbacksFun():
logger.debug("just a wrapper really")
return do_some_stuff() # this is ok too - the caller will yield on
# it anyway.
```
Provided this pattern is followed all the way back up to the callchain
to where the logcontext was set, this will make things work out ok:
provided `do_some_stuff` and `more_stuff` follow the rules above, then
so will `fun` (as wrapped by `inlineCallbacks`) and
`nonInlineCallbacksFun`.
so will `fun`.
It's all too easy to forget to `yield`: for instance if we forgot that
`do_some_stuff` returned a deferred, we might plough on regardless. This
It's all too easy to forget to `await`: for instance if we forgot that
`do_some_stuff` returned an awaitable, we might plough on regardless. This
leads to a mess; it will probably work itself out eventually, but not
before a load of stuff has been logged against the wrong context.
(Normally, other things will break, more obviously, if you forget to
`yield`, so this tends not to be a major problem in practice.)
`await`, so this tends not to be a major problem in practice.)
Of course sometimes you need to do something a bit fancier with your
Deferreds - not all code follows the linear A-then-B-then-C pattern.
awaitable - not all code follows the linear A-then-B-then-C pattern.

## Passing synapse deferreds into third-party functions
A typical example of this is where we want to collect together two or
more deferred via `defer.gatherResults`:
more awaitables via `defer.gatherResults`:
```python
d1 = operation1()
d2 = operation2()
d3 = defer.gatherResults([d1, d2])
a1 = operation1()
a2 = operation2()
a3 = defer.gatherResults([a1, a2])
```

we are firing off `d1` and `d2` without yielding on them. The difference
we are firing off `a1` and `a2` without awaiting on them. The difference
is that we now have third-party code attached to their callbacks. Anyway
either technique given in the [Fire-and-forget](#fire-and-forget)
section will work.
Of course, the new Deferred returned by `gatherResults` needs to be
Of course, the new awaitable returned by `gather` needs to be
wrapped in order to make it follow the logcontext rules before we can
yield it, as described in [Where you create a new Deferred, make it
yield it, as described in [Where you create a new awaitable, make it
follow the
rules](#where-you-create-a-new-deferred-make-it-follow-the-rules).
rules](#where-you-create-a-new-awaitable-make-it-follow-the-rules).
So, option one: reset the logcontext before starting the operations to
be gathered:
```python
@defer.inlineCallbacks
def do_request_handling():
async def do_request_handling():
with PreserveLoggingContext():
d1 = operation1()
d2 = operation2()
result = yield defer.gatherResults([d1, d2])
a1 = operation1()
a2 = operation2()
result = await defer.gatherResults([a1, a2])
```
In this case particularly, though, option two, of using
`context.preserve_fn` almost certainly makes more sense, so that
`context.run_in_background` almost certainly makes more sense, so that
`operation1` and `operation2` are both logged against the original
logcontext. This looks like:
```python
@defer.inlineCallbacks
def do_request_handling():
d1 = context.preserve_fn(operation1)()
d2 = context.preserve_fn(operation2)()
async def do_request_handling():
a1 = context.run_in_background(operation1)
a2 = context.run_in_background(operation2)
with PreserveLoggingContext():
result = yield defer.gatherResults([d1, d2])
result = await make_deferred_yieldable(defer.gatherResults([a1, a2]))
```
## Was all this really necessary?
## A note on garbage-collection of awaitable chains
The conventions used work fine for a linear flow where everything
happens in series via `defer.inlineCallbacks` and `yield`, but are
certainly tricky to follow for any more exotic flows. It's hard not to
wonder if we could have done something else.
We're not going to rewrite Synapse now, so the following is entirely of
academic interest, but I'd like to record some thoughts on an
alternative approach.
I briefly prototyped some code following an alternative set of rules. I
think it would work, but I certainly didn't get as far as thinking how
it would interact with concepts as complicated as the cache descriptors.
My alternative rules were:
- functions always preserve the logcontext of their caller, whether or
not they are returning a Deferred.
- Deferreds returned by synapse functions run their callbacks in the
same context as the function was orignally called in.
The main point of this scheme is that everywhere that sets the
logcontext is responsible for clearing it before returning control to
the reactor.
So, for example, if you were the function which started a
`with LoggingContext` block, you wouldn't `yield` within it --- instead
you'd start off the background process, and then leave the `with` block
to wait for it:
```python
def handle_request(request_id):
with context.LoggingContext() as request_context:
request_context.request = request_id
d = do_request_handling()
def cb(r):
logger.debug("finished")
d.addCallback(cb)
return d
```
(in general, mixing `with LoggingContext` blocks and
`defer.inlineCallbacks` in the same function leads to slighly
counter-intuitive code, under this scheme).
Because we leave the original `with` block as soon as the Deferred is
returned (as opposed to waiting for it to be resolved, as we do today),
the logcontext is cleared before control passes back to the reactor; so
if there is some code within `do_request_handling` which needs to wait
for a Deferred to complete, there is no need for it to worry about
clearing the logcontext before doing so:
```python
def handle_request():
r = do_some_stuff()
r.addCallback(do_some_more_stuff)
return r
```
--- and provided `do_some_stuff` follows the rules of returning a
Deferred which runs its callbacks in the original logcontext, all is
happy.
The business of a Deferred which runs its callbacks in the original
logcontext isn't hard to achieve --- we have it today, in the shape of
`context._PreservingContextDeferred`:
```python
def do_some_stuff():
deferred = do_some_io()
pcd = _PreservingContextDeferred(LoggingContext.current_context())
deferred.chainDeferred(pcd)
return pcd
```
It turns out that, thanks to the way that Deferreds chain together, we
automatically get the property of a context-preserving deferred with
`defer.inlineCallbacks`, provided the final Defered the function
`yields` on has that property. So we can just write:
```python
@defer.inlineCallbacks
def handle_request():
yield do_some_stuff()
yield do_some_more_stuff()
```
To conclude: I think this scheme would have worked equally well, with
less danger of messing it up, and probably made some more esoteric code
easier to write. But again --- changing the conventions of the entire
Synapse codebase is not a sensible option for the marginal improvement
offered.
## A note on garbage-collection of Deferred chains

and is under no obligation to implement all callbacks from the categories it registers
callbacks for.
Modules can register callbacks using one of the module API's `register_[...]_callbacks`
methods. The callback functions are passed to these methods as keyword arguments, with
the callback name as the argument name and the function as its value. This is demonstrated
in the example below. A `register_[...]_callbacks` method exists for each module type
documented in this section.
#### Spam checker callbacks
To register one of the callbacks described in this section, a module needs to use the
module API's `register_spam_checker_callbacks` method. The callback functions are passed
to `register_spam_checker_callbacks` as keyword arguments, with the callback name as the
argument name and the function as its value. This is demonstrated in the example below.
Spam checker callbacks allow module developers to implement spam mitigation actions for
Synapse instances. Spam checker callbacks can be registered using the module API's
`register_spam_checker_callbacks` method.

file_info: "synapse.rest.media.v1._base.FileInfo"
file_info: "synapse.rest.media.v1._base.FileInfo",
) -> bool
```
Called when storing a local or remote file. The module must return a boolean indicating
whether the given file can be stored in the homeserver's media store.
#### Account validity callbacks
Account validity callbacks allow module developers to add extra steps to verify the
validity on an account, i.e. see if a user can be granted access to their account on the
Synapse instance. Account validity callbacks can be registered using the module API's
`register_account_validity_callbacks` method.
The available account validity callbacks are:
```python
async def is_user_expired(user: str) -> Optional[bool]
```
Called when processing any authenticated request (except for logout requests). The module
can return a `bool` to indicate whether the user has expired and should be locked out of
their account, or `None` if the module wasn't able to figure it out. The user is
represented by their Matrix user ID (e.g. `@alice:example.com`).
If the module returns `True`, the current request will be denied with the error code
`ORG_MATRIX_EXPIRED_ACCOUNT` and the HTTP status code 403. Note that this doesn't
invalidate the user's access token.
```python
async def on_user_registration(user: str) -> None
```
Called after successfully registering a user, in case the module needs to perform extra
operations to keep track of them. (e.g. add them to a database table). The user is
represented by their Matrix user ID.
#### Third party rules callbacks
Third party rules callbacks allow module developers to add extra checks to verify the
validity of incoming events. Third party event rules callbacks can be registered using
the module API's `register_third_party_rules_callbacks` method.
The available third party rules callbacks are:
```python
async def check_event_allowed(
event: "synapse.events.EventBase",
state_events: "synapse.types.StateMap",
) -> Tuple[bool, Optional[dict]]
```
**<span style="color:red">
This callback is very experimental and can and will break without notice. Module developers
are encouraged to implement `check_event_for_spam` from the spam checker category instead.
</span>**
Called when processing any incoming event, with the event and a `StateMap`
representing the current state of the room the event is being sent into. A `StateMap` is
a dictionary that maps tuples containing an event type and a state key to the
corresponding state event. For example retrieving the room's `m.room.create` event from
the `state_events` argument would look like this: `state_events.get(("m.room.create", ""))`.
The module must return a boolean indicating whether the event can be allowed.
Note that this callback function processes incoming events coming via federation
traffic (on top of client traffic). This means denying an event might cause the local
copy of the room's history to diverge from that of remote servers. This may cause
federation issues in the room. It is strongly recommended to only deny events using this
callback function if the sender is a local user, or in a private federation in which all
servers are using the same module, with the same configuration.
If the boolean returned by the module is `True`, it may also tell Synapse to replace the
event with new data by returning the new event's data as a dictionary. In order to do
that, it is recommended the module calls `event.get_dict()` to get the current event as a
dictionary, and modify the returned dictionary accordingly.
Note that replacing the event only works for events sent by local users, not for events
received over federation.
```python
async def on_create_room(
requester: "synapse.types.Requester",
request_content: dict,
is_requester_admin: bool,
) -> None
```
Called when processing a room creation request, with the `Requester` object for the user
performing the request, a dictionary representing the room creation request's JSON body
(see [the spec](https://matrix.org/docs/spec/client_server/latest#post-matrix-client-r0-createroom)
for a list of possible parameters), and a boolean indicating whether the user performing
the request is a server admin.
Modules can modify the `request_content` (by e.g. adding events to its `initial_state`),
or deny the room's creation by raising a `module_api.errors.SynapseError`.

# Synapse Developer Documentation

* **subject**: Something we are tracking stats about – currently a room or user.
* **current row**: An entry for a subject in the appropriate current statistics
table. Each subject can have only one.
* **historical row**: An entry for a subject in the appropriate historical
statistics table. Each subject can have any number of these.
### Overview
Stats are maintained as time series. There are two kinds of column:
* absolute columns – where the value is correct for the time given by `end_ts`
in the stats row. (Imagine a line graph for these values)
* They can also be thought of as 'gauges' in Prometheus, if you are familiar.
* per-slice columns – where the value corresponds to how many of the occurrences
occurred within the time slice given by `(end_ts − bucket_size)…end_ts`
or `start_ts…end_ts`. (Imagine a histogram for these values)
Stats are maintained in two tables (for each type): current and historical.
Current stats correspond to the present values. Each subject can only have one
entry.
Historical stats correspond to values in the past. Subjects may have multiple
entries.
## Concepts around the management of stats
### Current rows
Current rows contain the most up-to-date statistics for a room.
They only contain absolute columns
### Historical rows
Historical rows can always be considered to be valid for the time slice and
end time specified.
* historical rows will not exist for every time slice – they will be omitted
if there were no changes. In this case, the following assumptions can be
made to interpolate/recreate missing rows:
- absolute fields have the same values as in the preceding row
- per-slice fields are zero (`0`)
* historical rows will not be retained forever – rows older than a configurable
time will be purged.
#### Purge
The purging of historical rows is not yet implemented.
Stats correspond to the present values. Current rows contain the most up-to-date
statistics for a room. Each subject can only have one entry.
