Synapse 1.32.2 (2021-04-22)
===========================
This release includes a fix for a regression introduced in 1.32.0.
Bugfixes
--------
- Fix a regression in Synapse 1.32.0 and 1.32.1 which caused `LoggingContext` errors in plugins. ([\#9857](https://github.com/matrix-org/synapse/issues/9857))
1.32.0 also introduced an incompatibility with Synapse modules that make use of `synapse.logging.context.LoggingContext`, such as [synapse-s3-storage-provider](https://github.com/matrix-org/synapse-s3-storage-provider).
This PR adds a note to the 1.32.0 changelog and upgrade notes about it.
===========================
This release fixes [a
regression](https://github.com/matrix-org/synapse/issues/9853)
in Synapse 1.32.0 that caused connected Prometheus instances to become
unstable. If you
ran Synapse 1.32.0 with Prometheus metrics, first upgrade to Synapse
1.32.1 and follow
[these
instructions](https://github.com/matrix-org/synapse/pull/9854#issuecomment-823472183)
to clean up any excess writeahead logs.
Bugfixes
--------
- Fix a regression in Synapse 1.32.0 which caused Synapse to report
large numbers of Prometheus time series, potentially overwhelming
Prometheus instances.

As far as I can tell our logging contexts are meant to log the request ID, or sometimes the request ID followed by a suffix (this is generally stored in the name field of LoggingContext). There's also code to log the name@memory location, but I'm not sure this is ever used.
This simplifies the code paths to require every logging context to have a name and use that in logging. For sub-contexts (created via nested_logging_contexts, defer_to_threadpool, Measure) we use the current context's str (which becomes their name or the string "sentinel") and then potentially modify that (e.g. add a suffix).
This attempts to be a direct port of https://github.com/matrix-org/synapse-dinsic/pull/74 to mainline. There was some fiddling required to deal with the changes that have been made to mainline since (mainly dealing with the split of `RegistrationWorkerStore` from `RegistrationStore`, and the changes made to `self.make_request` in test code).
When receiving a /send_join request for a room with join rules set to 'restricted',
check if the user is a member of the spaces defined in the 'allow' key of the join
rules.
This only applies to an experimental room version, as defined in MSC3083.
This basically speeds up federation by "squeezing" each individual dual database call (to destinations and destination_rooms), which previously happened per every event, into one call for an entire batch (100 max).
