Found this by accident while poking around on room creation optimisation; two things:

  • Use same get events stream DB query as the federation senders do in the appservice worker
    • this moves the AS pusher closer to the federation sender instances - which we'd like to setup to run multiple AS pushers in parallel just as you can fed senders
    • de-dupes the two near-identical functions into one for a bit of cleanup
  • Pull down event received TS in the stream query and thus remove the additional query to fetch this
    • the received TS is fetched per event processed by both of these workers, so this has potential to yield a significant reduction in query traffic depending on the synapse install/size/content

@Fizzadar
Replace get_new_events_for_appservice with get_all_new_events_stream
b42c899 
The functions were near identical and this brings the AS worker closer
to the way federation senders work which can allow for multiple workers
to handle AS traffic.
@Fizzadar
Pull received TS alongside events when processing the stream
9910139 
This avoids an extra query -per event- when both federation sender
and appservice pusher process events.

Am I right in thinking that this rewrite of set_appservice_last_pos is non-functional and just a cleanup?

Yep just switched to the simple query versions for consistency elsewhere, no functional change.

Merge tag 'v1.64.0' into merge_v1_64_0
b4863c7 
Synapse 1.64.0 (2022-08-02)
===========================

No significant changes since 1.64.0rc2.

Deprecation Warning
-------------------

Synapse v1.66.0 will remove the ability to delegate the tasks of verifying email address ownership, and password reset confirmation, to an identity server.

If you require your homeserver to verify e-mail addresses or to support password resets via e-mail, please configure your homeserver with SMTP access so that it can send e-mails on its own behalf.
[Consult the configuration documentation for more information.](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#email)

Synapse 1.64.0rc2 (2022-07-29)
==============================

This RC reintroduces support for `account_threepid_delegates.email`, which was removed in 1.64.0rc1. It remains deprecated and will be removed altogether in Synapse v1.66.0. ([\matrix-org#13406](matrix-org#13406))

Synapse 1.64.0rc1 (2022-07-26)
==============================

This RC removed the ability to delegate the tasks of verifying email address ownership, and password reset confirmation, to an identity server.

We have also stopped building `.deb` packages for Ubuntu 21.10 as it is no longer an active version of Ubuntu.

Features
--------

- Improve error messages when media thumbnails cannot be served. ([\matrix-org#13038](matrix-org#13038))
- Allow pagination from remote event after discovering it from [MSC3030](matrix-org/matrix-spec-proposals#3030) `/timestamp_to_event`. ([\matrix-org#13205](matrix-org#13205))
- Add a `room_type` field in the responses for the list room and room details admin APIs. Contributed by @andrewdoh. ([\matrix-org#13208](matrix-org#13208))
- Add support for room version 10. ([\matrix-org#13220](matrix-org#13220))
- Add per-room rate limiting for room joins. For each room, Synapse now monitors the rate of join events in that room, and throttles additional joins if that rate grows too large. ([\matrix-org#13253](matrix-org#13253), [\matrix-org#13254](matrix-org#13254), [\matrix-org#13255](matrix-org#13255), [\matrix-org#13276](matrix-org#13276))
- Support Implicit TLS (TLS without using a STARTTLS upgrade, typically on port 465) for sending emails, enabled by the new option `force_tls`. Contributed by Jan Schär. ([\matrix-org#13317](matrix-org#13317))

Bugfixes
--------

- Fix a bug introduced in Synapse 1.15.0 where adding a user through the Synapse Admin API with a phone number would fail if the `enable_email_notifs` and `email_notifs_for_new_users` options were enabled. Contributed by @thomasweston12. ([\matrix-org#13263](matrix-org#13263))
- Fix a bug introduced in Synapse 1.40.0 where a user invited to a restricted room would be briefly unable to join. ([\matrix-org#13270](matrix-org#13270))
- Fix a long-standing bug where, in rare instances, Synapse could store the incorrect state for a room after a state resolution. ([\matrix-org#13278](matrix-org#13278))
- Fix a bug introduced in v1.18.0 where the `synapse_pushers` metric would overcount pushers when they are replaced. ([\matrix-org#13296](matrix-org#13296))
- Disable autocorrection and autocapitalisation on the username text field shown during registration when using SSO. ([\matrix-org#13350](matrix-org#13350))
- Update locked version of `frozendict` to 2.3.3, which has fixes for memory leaks affecting `/sync`. ([\matrix-org#13284](matrix-org#13284), [\matrix-org#13352](matrix-org#13352))

Improved Documentation
----------------------

- Provide an example of using the Admin API. Contributed by @jejo86. ([\matrix-org#13231](matrix-org#13231))
- Move the documentation for how URL previews work to the URL preview module. ([\matrix-org#13233](matrix-org#13233), [\matrix-org#13261](matrix-org#13261))
- Add another `contrib` script to help set up worker processes. Contributed by @villepeh. ([\matrix-org#13271](matrix-org#13271))
- Document that certain config options were added or changed in Synapse 1.62. Contributed by @behrmann. ([\matrix-org#13314](matrix-org#13314))
- Document the new `rc_invites.per_issuer` throttling option added in Synapse 1.63. ([\matrix-org#13333](matrix-org#13333))
- Mention that BuildKit is needed when building Docker images for tests. ([\matrix-org#13338](matrix-org#13338))
- Improve Caddy reverse proxy documentation. ([\matrix-org#13344](matrix-org#13344))

Deprecations and Removals
-------------------------

- Drop tables that were formerly used for groups/communities. ([\matrix-org#12967](matrix-org#12967))
- Drop support for delegating email verification to an external server. ([\matrix-org#13192](matrix-org#13192))
- Drop support for calling `/_matrix/client/v3/account/3pid/bind` without an `id_access_token`, which was not permitted by the spec. Contributed by @Vetchu. ([\matrix-org#13239](matrix-org#13239))
- Stop building `.deb` packages for Ubuntu 21.10 (Impish Indri), which has reached end of life. ([\matrix-org#13326](matrix-org#13326))

- Further reduce queries used sending events when creating new rooms. Contributed by Nick @ Beeper (@Fizzadar). ([\matrix-org#13224](matrix-org#13224))
- Call the v2 identity service `/3pid/unbind` endpoint, rather than v1. Contributed by @Vetchu. ([\matrix-org#13240](matrix-org#13240))

- Reduce the rebuild time for the complement-synapse docker image. ([\matrix-org#13279](matrix-org#13279))
- Don't pull out the full state when creating an event. ([\matrix-org#13281](matrix-org#13281), [\matrix-org#13307](matrix-org#13307))
- Upgrade from Poetry 1.1.12 to 1.1.14, to fix bugs when locking packages. ([\matrix-org#13285](matrix-org#13285))
- Make `DictionaryCache` expire full entries if they haven't been queried in a while, even if specific keys have been queried recently. ([\matrix-org#13292](matrix-org#13292))

- Change `get_users_in_room` and `get_rooms_for_user` caches to enable pruning of old entries. ([\matrix-org#13313](matrix-org#13313))
- Validate federation destinations and log an error if a destination is invalid. ([\matrix-org#13318](matrix-org#13318))
- Fix `FederationClient.get_pdu()` returning events from the cache as `outliers` instead of original events we saw over federation. ([\matrix-org#13320](matrix-org#13320))
- Reduce memory usage of state caches. ([\matrix-org#13323](matrix-org#13323))
- Reduce the amount of state we store in the `state_cache`. ([\matrix-org#13324](matrix-org#13324))
- Add missing type hints to open tracing module. ([\matrix-org#13328](matrix-org#13328), [\matrix-org#13345](matrix-org#13345), [\matrix-org#13362](matrix-org#13362))
- Remove old base slaved store and de-duplicate cache ID generators. Contributed by Nick @ Beeper (@Fizzadar). ([\matrix-org#13329](matrix-org#13329), [\matrix-org#13349](matrix-org#13349))
- When reporting metrics is enabled, use ~8x less data to describe DB transaction metrics. ([\matrix-org#13342](matrix-org#13342))
- Faster room joins: skip soft fail checks while Synapse only has partial room state, since the current membership of event senders may not be accurately known. ([\matrix-org#13354](matrix-org#13354))
