When upgrading a room to v12, we accidentally ended up mutating the
content of the old power level. Since we cache events, this meant any
future usage of the old power level event would see the wrong content
(until it dropped from the cache).
This meant that the creator of the new room would not be able to perform
admin actions on the old room. Any federation requests for the event
would fail the hash checks, since the content had been changed.
All in all, quite a nasty bug.
MSC3266 is merged in v1.15, let's stabilize it as part of #18731
1. Add support for the stable `/_matrix/client/v1/room_summary/`
endpoint, keeping both unstable endpoints for compat
2. Remove the experimental `msc3266_enabled` flag
This fixes the bug described in #19713 (and double-checked against the
SDK integration test, which now passes with this change). A sync
response must be returned immediately if a room subscription
configuration change caused a new non-empty response (checked with `if
response` in the code) to be produced.
Fixes#19713.
Fixes#18844.

Currently synapse returns `M_FORBIDDEN` when trying to use the account
deactivation API, if the server admin disabled displayname changes. This
is undesirable, since it prevents GDPR erasure without admin
interaction. The admin API seems to work fine though. This also only
seems to affect the deactivate API, when the erase flag is true.
Relevant endpoint:
https://spec.matrix.org/latest/client-server-api/#post_matrixclientv3accountdeactivate
This change only removes the checked for condition that the displayname
and profile avatar are allowed to be changed per the configuration
setting. If a user is deleting themselves, why is that denied?
There did not seem to be a basic test for this endpoint that checks the
`erase` usage, so that was added as well as checking the above mentioned
behavior.
Both `__getitem__` and `.user_id` were removed in #19680 to simplify the
event class. However, `EventBase` is exposed to modules who might also
make use of those methods, so let's reinstate them (but otherwise not
reinstate the usage of them in the code).
Follows on from #19473.
We should be recording where we have deleted up to in the same
transaction as we perform the delete, rather than at the end. This code
only starts deleting rows after a month (and the original PR isn't in a
release yet), so no server should have run into this problem yet.
Also let's log more regularly, as the initial set of deletions will
likely take a long time.
Fixes#13043
The usages of the table mostly already correctly handled if we don't
have old entries, as that was needed when we first added the table.
I arbitrarily set the prune time to 30 days. The only use for old
entries is for sync streams that haven't synced since then, and we
should very rarely see sync streams that haven't been used in 30 days.
Reviewable commit-by-commit.

Closes: #19688
Part of: MSC4450 whose Experimental Feature tracking issue is #19691
Add an unstable, namespaced `idp_id` query parameter to `fallback/web` \
This allows clients to specify the identity provider they'd like to log
in with for SSO when they have multiple upstream IdPs associated with
their account.
Previously, Synapse would just pick one arbitrarily. But this was
undesirable as you may want to use a different one at that point in
time. When logging in, the user is able to choose when IdP they use -
during UIA (which uses fallback auth mechanism) they should be able to
do the same.

This moves the reference counting from PyO3 into standard Rust types,
allowing the class to be used natively from Rust without needing a
Python runtime.
When we return events to clients we need to annotate them with the
membership of the user at the time of the event, in the `unsigned`
section. We already check the membership at the event during the
visibility checks, and so we annotate events there. However, since this
a per-user field we end up having to clone the event in question.
Instead, let's add a `FilteredEvent` class that is returned by the
visibility checks, which allows returning the membership without editing
the event. This has three benefits:
1. Avoids the clones of the event.
2. Allows us to statically check that we have filtered events before
returning them to clients.
3. We no longer edit `unsigned` data after event deserialization, this
makes it easier to port the event class to Rust.
The last benefit is why we're doing this *now*, however IMV it shouldn't
affect whether we want this change or not.

Fixes: #19616
This caused 2+ people trouble now, so worth batting away with a
low-effort change if we can.
Only seen on macOS so far, but nothing stops SQLite being configured in
defensive mode by default on other platforms, so it is not necessarily
entirely specific to macOS.
We *could* also do this for Python < 3.12 but it'd be more effort and I
don't know if it's worth it.
(For context @kegsay says the interpreter with this problem was
installed through `pyenv install`.)

Follows: #19365
Part of: MSC4354 Sticky Events (experimental feature #19409)
This PR introduces a `spam_checker_spammy` flag, analogous to
`policy_server_spammy`, as an explicit flag
that an event was decided to be spammy by a spam-checker module.
The original Sticky Events PR (#18968) just reused
`policy_server_spammy`, but it didn't sit right with me
because we (at least appear to be experimenting with features that)
allow users to opt-in to seeing
`policy_server_spammy` events (presumably for moderation purposes).
Keeping these flags separate felt best, therefore.
As for why we need this flag: soon soft-failed status won't be
permanent, at least for sticky events.
The spam checker modules currently work by making events soft-failed.
We want to prevent spammy events from getting
reconsidered/un-soft-failed, so it seems like we need
a flag to track spam-checker spamminess *separately* from soft-failed.
Should be commit-by-commit friendly, but is also small.

This is to make it easier to port to Rust, as well as making things
conceptually simpler.
Two changes:
1. Remove the `__getitem__` interface on events
2. Remove `.user_id` as an alias of `.sender`.
The spec says `device_keys` may be omitted, but not set to `null`.
This was temporarily allowed as a workaround for misbehaving clients
(see #19023), which have since been fixed.
Fixes#19030
