By scraping Open Graph information from the HTML even
when an autodiscovery endpoint is found. The results are
then combined to capture as much information as possible
from the page.
I've never found this terribly useful. I think it was added in the early days
of Synapse, without much thought as to what would actually be useful to log,
and has just been cargo-culted ever since.
Rather, it tends to clutter up debug logs with useless information.
The existing implementation of the `python_twisted_reactor_tick_time` metric is pretty useless, because it *only*
measures the time taken to execute timed calls and callbacks from threads. That neglects everything that
happens off the back of I/O, which is obviously quite a lot for us.
To improve this, I've hooked into a different place in the reactor - in particular, where it calls `epoll`. That call is
the only place it should wait for something to happen - the rest of the loop *should* be quick.
I've also removed `python_twisted_reactor_pending_calls`, because I don't believe anyone ever looks at it, and
it's a nuisance to populate.
Always add state.room_id after the configurable ORDER BY. Otherwise,
for any sort, certain pages can contain results from
other pages. (Especially when sorting by creator, since there may
be many rooms by the same creator)
* Document different order direction of numerical fields
"joined_members", "joined_local_members", "version" and "state_events"
are ordered in descending direction by default (dir=f). Added a note
in tests to explain the differences in ordering.

Rather than hooking into the reactor loop, just add a timed task that runs every 100 ms to do the garbage collection.
Part 1 of a quest to simplify the reactor monkey-patching.
Currently when puppeting another user, the user doing the puppeting is
tracked for client IPs and MAU (if configured).
When tracking MAU is important, it becomes necessary to be possible to
also track the client IPs and MAU of puppeted users. As an example a
client that manages user creation and creation of tokens via the Synapse
admin API, passing those tokens for the client to use.
This PR adds optional configuration to enable tracking of puppeted users
into monthly active users. The default behaviour stays the same.

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.
* Optionally use an on-disk sqlite db in tests
When debugging a test it is sometimes useful to inspect the state of the
DB. This is not easy when the db is in-memory: one cannot attach the
sqlite CLI to another process's DB.
With this change, if SYNAPSE_TEST_PERSIST_SQLITE_DB is set, we use
`_trial_temp/test.db` as our sqlite database. One can then use
`sqlite3 _trial_temp/test.db` and query to your heart's content.
The DB is destroyed and recreated between different test cases.

This makes the serialization of events synchronous (and it no
longer access the database), but we must manually calculate and
provide the bundled aggregations.
Overall this should cause no change in behavior, but is prep work
for other improvements.
Fixes minor discrepancies between the /hierarchy endpoint described
in MSC2946 and the implementation.
Note that the changes impact the stable and unstable /hierarchy and
unstable /spaces endpoints for both client and federation APIs.
* `_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
* Fix AssertionErrors after purging events
If you purged a bunch of events from your database, and then restarted synapse
without receiving more events, then you would get a bunch of AssertionErrors on
restart.
This fixes the situation by rewinding the stream processors.
* `check-newsfragment`: ignore deleted newsfiles
Events returned by `backfill` should not be flagged as outliers.
Fixes:
```

* Push `get_room_{min,max_stream_ordering}` into StreamStore
Both implementations of this are identical, so we may as well push it down and
get rid of the abstract base class nonsense.
* Remove redundant `StreamStore` class
This is empty now
* Remove redundant `get_current_events_token`
This was an exact duplicate of `get_room_max_stream_ordering`, so let's get rid
of it.
* newsfile
* remove python 3.6 and postgres 9.6 from github workflow
* remove python 3.6 env from tox
* newsfragment
* correct postgres version
* add py310 to tox env list
* Wrap `auth.get_user_by_req` in an opentracing span
give `get_user_by_req` its own opentracing span, since it can result in a
non-trivial number of sub-spans which it is useful to group together.
This requires a bit of reorganisation because it also sets some tags (and may
force tracing) on the servlet span.
* Emit opentracing span for encoding json responses
This can be a significant time sink.
* Rename all sync spans with a prefix
* Write an opentracing span for encoding sync response
* opentracing span to group generate_room_entries
* opentracing spans within sync.encode_response
* changelog
* Use the `trace` decorator instead of context managers
This adds some opentracing annotations to ResponseCache, to make it easier to see what's going on; in particular, it adds a link back to the initial trace which is actually doing the work of generating the response.
* remove `start_active_span_from_request`
Instead, pull out a separate function, `span_context_from_request`, to extract
the parent span, which we can then pass into `start_active_span` as
normal. This seems to be clearer all round.
* Remove redundant tags from `incoming-federation-request`
These are all wrapped up inside a parent span generated in AsyncResource, so
there's no point duplicating all the tags that are set there.
* Leave request spans open until the request completes
It may take some time for the response to be encoded into JSON, and that JSON
to be streamed back to the client, and really we want that inside the top-level
span, so let's hand responsibility for closure to the SynapseRequest.
* opentracing logs for HTTP request events
* changelog
* Disable aggregation bundling on `/sync` responses
A partial revert of #11478. This turns out to have had a significant CPU impact
on initial-sync handling. For now, let's disable it, until we find a more
efficient way of achieving this.
* Fix tests.

A partial revert of #11478. This turns out to have had a significant CPU impact
on initial-sync handling. For now, let's disable it, until we find a more
efficient way of achieving this.
A couple of safety-checks to hopefully stop people doing what I just did, and create a storage
function which only works the first time it is called (and not when it is re-run due to a database
concurrency error or similar).
* Splits the logic for parsing HTML from the resource handling code.
* Fix a circular import in the oEmbed code (which uses the HTML parsing code).
* Renames some of the HTML parsing methods to:
* Make it clear which methods are "internal" to the module.
* Clarify what the methods do.
Create a new dict helper method `simple_insert_many_values_txn`, which takes
raw row values, rather than {key=>value} dicts. This saves us a bunch of dict
munging, and makes it easier to use generators rather than creating
intermediate lists and dicts.

After #10847, `looping_background_call` would print an error in the logs
every time a non-async function was called. Since the error would be
caught and ignored immediately, there were no other side effects.
Due to updates to MSC2675 this includes a few fixes:
* Include bundled aggregations for /sync.
* Do not include bundled aggregations for /initialSync and /events.
* Do not bundle aggregations for state events.
* Clarifies comments and variable names.
by calling into `make_test_homeserver_synchronous`.
The function *could* have been inlined at this point but the function is big enough
and it felt fine to leave it as is.
At least there isn't a confusing name clash anymore!
It had no users.
We have just taken the identity of a previous function but don't provide the same
behaviour, so we need to fix this in the next commit...
This mainly consists of docstrings and inline comments. There are one or two type annotations and variable renames thrown in while I was here.

When all entries in an `LruCache` have a size of 0 according to the
provided `size_callback`, and `drop_from_cache` is called on a cache
node, the node would be unlinked from the LRU linked list but remain in
the cache dictionary. An assertion would be later be tripped due to the
inconsistency.
Avoid unintentionally calling `__len__` and use a strict `is None`
check instead when unwrapping the weak reference.

The previous fix for the ongoing event fetches counter
(8eec25a1d9) was both insufficient and
incorrect.
When the database is unreachable, `_do_fetch` never gets run and so
`_event_fetch_ongoing` is never decremented.
The previous fix also moved the `_event_fetch_ongoing` decrement outside
of the `_event_fetch_lock` which allowed race conditions to corrupt the
counter.
This change makes mypy complain if the constants are ever reassigned,
and, more usefully, makes mypy type them as `Literal`s instead of `str`s,
allowing code of the following form to pass mypy:
```py
def do_something(membership: Literal["join", "leave"], ...): ...
do_something(Membership.JOIN, ...)

Synapse 1.47.1 (2021-11-23)
===========================
This release fixes a security issue in the media store, affecting all prior releases of Synapse. Server administrators are encouraged to update Synapse as soon as possible. We are not aware of these vulnerabilities being exploited in the wild.
Server administrators who are unable to update Synapse may use the workarounds described in the linked GitHub Security Advisory below.
Security advisory
-----------------
The following issue is fixed in 1.47.1.
- **[GHSA-3hfw-x7gx-437c](https://github.com/matrix-org/synapse/security/advisories/GHSA-3hfw-x7gx-437c) / [CVE-2021-41281](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-41281): Path traversal when downloading remote media.**
Synapse instances with the media repository enabled can be tricked into downloading a file from a remote server into an arbitrary directory, potentially outside the media store directory.
The last two directories and file name of the path are chosen randomly by Synapse and cannot be controlled by an attacker, which limits the impact.
Homeservers with the media repository disabled are unaffected. Homeservers configured with a federation whitelist are also unaffected.
Fixed by [91f2bd090](https://github.com/matrix-org/synapse/commit/91f2bd090).
Instead of only known relation types. This also reworks the background
update for thread relations to crawl events and search for any relation
type, not just threaded relations.
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.
Fixes a bug introduced in #11129: objects signed by the local server, but with
keys other than the current one, could not be successfully verified.
We need to check the key id in the signature, and track down the right key.

Adds validation to the Client-Server API to ensure that
the potential thread head does not relate to another event
already. This results in not allowing a thread to "fork" into
other threads.
If the target event is unknown for some reason (maybe it isn't
visible to your homeserver), but is the target of other events
it is assumed that the thread can be created from it. Otherwise,
it is rejected as an unknown event.
Otherwise I get this beautiful stacktrace:
```

Synapse 1.47.0rc2 (2021-11-10)
==============================
This fixes an issue with publishing the Debian packages for 1.47.0rc1.
It is otherwise identical to 1.47.0rc1.
* Make lock better handle process being killed
If the process gets killed and restarted (so that it didn't have a
chance to drop its locks gracefully) then there may still be locks in
the DB that are for the same instance that haven't yet timed out but are
safe to delete.
We handle this case by a) checking if the current instance already has
taken out the lock, and b) if not then ignoring locks that are for the
same instance.
* Periodically check for old staged events
This is to protect against other instances dying and their locks timing
out.
* Remove unused Vagrant scripts
* Change package Architecture to any
* Preinstall the wheel package when building venvs.

When an event fetcher aborts due to an exception, `_event_fetch_ongoing`
must be decremented, otherwise the event fetcher would never be

Synapse 1.30.1 (2021-03-26)
===========================
This release is identical to Synapse 1.30.0, with the exception of explicitly
setting a minimum version of Python's Cryptography library to ensure that users
of Synapse are protected from the recent [OpenSSL security advisories](https://mta.openssl.org/pipermail/openssl-announce/2021-March/000198.html),
especially CVE-2021-3449.
Note that Cryptography defaults to bundling its own statically linked copy of
OpenSSL, which means that you may not be protected by your operating system's
security updates.
It's also worth noting that Cryptography no longer supports Python 3.5, so
admins deploying to older environments may not be protected against this or
future vulnerabilities. Synapse will be dropping support for Python 3.5 at the
end of March.
Updates to the Docker image
---------------------------
- Ensure that the docker container has up to date versions of openssl. ([\#9697](https://github.com/matrix-org/synapse/issues/9697))
Internal Changes
----------------
- Enforce that `cryptography` dependency is up to date to ensure it has the most recent openssl patches. ([\#9697](https://github.com/matrix-org/synapse/issues/9697))
We patched `matrix-org-hotfixes` a little while ago in #8675 to drop any cross-user key share requests while they were being accidentally spammed by a client. This was a temporary fix until we had some rate-limiting in place.
Rate-limiting landed in https://github.com/matrix-org/synapse/pull/8957. Note that the rate-limit can't be configured, but has what appear to be [sensible defaults](db2efa9c50/synapse/config/ratelimiting.py (L105-L113)).
Note that the original patch was already actually overridden partially when the rate-limit PR landed, as they conflicted. So we've already lifted the restriction between local devices on matrix.org, but requests were still blocked from being sent over federation. This PR cleans up the remaining bits.
This reverts commit d60af9305a.
Cross-user `m.key_share_requests` are a relatively new `to_device` message that allows user to re-request session keys for a message from another user if they were otherwise unable to retrieve them.
Unfortunately, these have had performance concerns on matrix.org. This is a temporary patch to disable them while we investigate a better solution.
This was added in 1c347c84bf/#7544 as a temporary optimisation. That was never
merged to develop, since it conflicted with #7492. The merge cf92310da forgot
to remove it.
This reverts b852a8247, 15b2a5081, 28889d8da.
I don't think these patches are required any more, and if they are, they should
be on mainline, not hidden in our hotfixes branch. Let's try backing them out:
if that turns out to be an error, we can PR them properly.
Instead of just using the most recent extremities let's pick the
ones that will give us results that the pagination request cares about,
i.e. pick extremities only if they have a smaller depth than the
pagination token.
This is useful when we fail to backfill an extremity, as we no longer
get stuck requesting that same extremity repeatedly.
This is a bit of a hack, as `_check_sigs_and_hash_and_fetch` is intended
for attempting to pull an event from the database/(re)pull it from the
server that originally sent the event if checking the signature of the
event fails.
During backfill we *know* that we won't have the event in our database,
however it is still useful to be able to query the original sending
server as the server we're backfilling from may be acting maliciously.
The main benefit and reason for this change however is that
`_check_sigs_and_hash_and_fetch` will drop an event during backfill if
it cannot be successfully validated, whereas the current code will
simply fail the backfill request - resulting in the client's /messages
request silently being dropped.
This is a quick patch to fix backfilling rooms that contain malformed
events. A better implementation in planned in future.

I think this was done back when most synapses would reject the
no-trailing-slash version; it's no longer required, and makes matrix.org spec-incompliant.
This reverts commit fc5be50d56.
Basically, if the federation sender starts getting behind, insert some sleeps
into the transaction transmission code to give the fed sender a chance to catch
up.
Might have to experiment a bit with the numbers.
Basically, if the federation sender starts getting behind, insert some sleeps

Might have to experiment a bit with the numbers.
This was some hacky code (introduced in c10c71e70d) to make the presence stream
do nothing on hotfixes. We now ensure that no replication clients subscribe to
the presence stream, so this is redundant.
This got done on the develop branch in #4635, but the subsequent merge to
hotfixes (88af0317a) discarded the changes for some reason.
Fixing this here and now means (a) there are fewer differences between
matrix-org-hotfixes and develop, making future patches easier to merge, and (b)
fixes some pep8 errors on the hotfixes branch which have been annoying me for
some time.
Firstly: we want to do this in a better way, which is the intention of
too many RRs, which means we need to make it happen again.

We no longer need this; please redo it as a proper MSC & synapse PR if you want
to keep it...
Presence is supposed to be disabled on matrix.org, so we shouldn't send a load
of USER_SYNC commands every time the synchrotron reconnects to the master.

Synapse 1.49.2 (2021-12-21)
===========================
This release fixes a regression introduced in Synapse 1.49.0 which could cause `/sync` requests to take significantly longer. This would particularly affect "initial" syncs for users participating in a large number of rooms, and in extreme cases, could make it impossible for such users to log in on a new client.
**Note:** in line with our [deprecation policy](https://matrix-org.github.io/synapse/latest/deprecation_policy.html) for platform dependencies, this will be the last release to support Python 3.6 and PostgreSQL 9.6, both of which have now reached upstream end-of-life. Synapse will require Python 3.7+ and PostgreSQL 10+.
**Note:** We will also stop producing packages for Ubuntu 18.04 (Bionic Beaver) after this release, as it uses Python 3.6.

Synapse 1.47.1 (2021-11-23)
===========================
This release fixes a security issue in the media store, affecting all prior releases of Synapse. Server administrators are encouraged to update Synapse as soon as possible. We are not aware of these vulnerabilities being exploited in the wild.
Server administrators who are unable to update Synapse may use the workarounds described in the linked GitHub Security Advisory below.
Security advisory
-----------------
The following issue is fixed in 1.47.1.
- **[GHSA-3hfw-x7gx-437c](https://github.com/matrix-org/synapse/security/advisories/GHSA-3hfw-x7gx-437c) / [CVE-2021-41281](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-41281): Path traversal when downloading remote media.**
Synapse instances with the media repository enabled can be tricked into downloading a file from a remote server into an arbitrary directory, potentially outside the media store directory.
The last two directories and file name of the path are chosen randomly by Synapse and cannot be controlled by an attacker, which limits the impact.
Homeservers with the media repository disabled are unaffected. Homeservers configured with a federation whitelist are also unaffected.
Fixed by [91f2bd090](https://github.com/matrix-org/synapse/commit/91f2bd090).
