Will this be a background update / schema delta or something manual? |
I'm assuming something automated, but haven't really gotten that far yet |

#9466 picks it up, by removing the different code paths between sharded and non-sharded push set ups. Though maybe we should start running our worker mode sytests with sharded pushers? |

Synapse 1.29.0 (2021-03-08) =========================== Note that synapse now expects an `X-Forwarded-Proto` header when used with a reverse proxy. Please see [UPGRADE.rst](UPGRADE.rst#upgrading-to-v1290) for more details on this change. No significant changes. Synapse 1.29.0rc1 (2021-03-04) ============================== Features -------- - Add rate limiters to cross-user key sharing requests. ([\#8957](matrix-org/synapse#8957)) - Add `order_by` to the admin API `GET /_synapse/admin/v1/users/<user_id>/media`. Contributed by @dklimpel. ([\#8978](matrix-org/synapse#8978)) - Add some configuration settings to make users' profile data more private. ([\#9203](matrix-org/synapse#9203)) - The `no_proxy` and `NO_PROXY` environment variables are now respected in proxied HTTP clients with the lowercase form taking precedence if both are present. Additionally, the lowercase `https_proxy` environment variable is now respected in proxied HTTP clients on top of existing support for the uppercase `HTTPS_PROXY` form and takes precedence if both are present. Contributed by Timothy Leung. ([\#9372](matrix-org/synapse#9372)) - Add a configuration option, `user_directory.prefer_local_users`, which when enabled will make it more likely for users on the same server as you to appear above other users. ([\#9383](matrix-org/synapse#9383), [\#9385](matrix-org/synapse#9385)) - Add support for regenerating thumbnails if they have been deleted but the original image is still stored. ([\#9438](matrix-org/synapse#9438)) - Add support for `X-Forwarded-Proto` header when using a reverse proxy. ([\#9472](matrix-org/synapse#9472), [\#9501](matrix-org/synapse#9501), [\#9512](matrix-org/synapse#9512), [\#9539](matrix-org/synapse#9539)) Bugfixes -------- - Fix a bug where users' pushers were not all deleted when they deactivated their account. ([\#9285](matrix-org/synapse#9285), [\#9516](matrix-org/synapse#9516)) - Fix a bug where a lot of unnecessary presence updates were sent when joining a room. ([\#9402](matrix-org/synapse#9402)) - Fix a bug that caused multiple calls to the experimental `shared_rooms` endpoint to return stale results. ([\#9416](matrix-org/synapse#9416)) - Fix a bug in single sign-on which could cause a "No session cookie found" error. ([\#9436](matrix-org/synapse#9436)) - Fix bug introduced in v1.27.0 where allowing a user to choose their own username when logging in via single sign-on did not work unless an `idp_icon` was defined. ([\#9440](matrix-org/synapse#9440)) - Fix a bug introduced in v1.26.0 where some sequences were not properly configured when running `synapse_port_db`. ([\#9449](matrix-org/synapse#9449)) - Fix deleting pushers when using sharded pushers. ([\#9465](matrix-org/synapse#9465), [\#9466](matrix-org/synapse#9466), [\#9479](matrix-org/synapse#9479), [\#9536](matrix-org/synapse#9536)) - Fix missing startup checks for the consistency of certain PostgreSQL sequences. ([\#9470](matrix-org/synapse#9470)) - Fix a long-standing bug where the media repository could leak file descriptors while previewing media. ([\#9497](matrix-org/synapse#9497)) - Properly purge the event chain cover index when purging history. ([\#9498](matrix-org/synapse#9498)) - Fix missing chain cover index due to a schema delta not being applied correctly. Only affected servers that ran development versions. ([\#9503](matrix-org/synapse#9503)) - Fix a bug introduced in v1.25.0 where `/_synapse/admin/join/` would fail when given a room alias. ([\#9506](matrix-org/synapse#9506)) - Prevent presence background jobs from running when presence is disabled. ([\#9530](matrix-org/synapse#9530)) - Fix rare edge case that caused a background update to fail if the server had rejected an event that had duplicate auth events. ([\#9537](matrix-org/synapse#9537)) Improved Documentation ---------------------- - Update the example systemd config to propagate reloads to individual units. ([\#9463](matrix-org/synapse#9463)) Internal Changes ---------------- - Add documentation and type hints to `parse_duration`. ([\#9432](matrix-org/synapse#9432)) - Remove vestiges of `uploads_path` configuration setting. ([\#9462](matrix-org/synapse#9462)) - Add a comment about systemd-python. ([\#9464](matrix-org/synapse#9464)) - Test that we require validated email for email pushers. ([\#9496](matrix-org/synapse#9496)) - Allow python to generate bytecode for synapse. ([\#9502](matrix-org/synapse#9502)) - Fix incorrect type hints. ([\#9515](matrix-org/synapse#9515), [\#9518](matrix-org/synapse#9518)) - Add type hints to device and event report admin API. ([\#9519](matrix-org/synapse#9519)) - Add type hints to user admin API. ([\#9521](matrix-org/synapse#9521)) - Bump the versions of mypy and mypy-zope used for static type checking.

The intent here was that we should ignore attempts to delete pushers on workers not responsible for that user's push. This is incorrect, as deleting pushers must happen on master. However, unless the
pusher_instancesconfig is set and non-emptyShardedWorkerHandlingConfig.should_handle(..)will always return true (for silly backwards compat reasons, which is fixed in a separate PR), and so the method ends up doing the right thing in that case.Since our integration tests for workers doesn't use
pusher_instancesall the tests passed, even though they broke if that option was set.We fix this by a) removing the condition and b) making
remove_pusherhit master over replication when called on workers (I don't think anything on workers call it, but it seemed easier to just add support for it). We also replace theREMOVE_PUSHERreplication command with a HTTP API (to make it reliable).I'm planning on clearing out pushers that should have been deleted in a separate PR.
