This one is slightly different, but I didn't see why it also shouldn't use isinstance?

I guess this would reject sub_dict[sub_fields] which were instances of a class that inherits from either dict or frozendict. I don't think we have a particularly good reason to do that though?

I note that:
- this doesn't unfreeze a frozenset to a set
- maybe the try-except could be replaced with an
if isinstance(o, collections.abc.Iterable)? - unfreezing a string bytestring still leaves you with an immutable object!
Judging from where we use it, it looks like this is only used to unfreeze event content rather than a generic unfreeze function.

I don't believe it is meant to be a generic unfreeze function. 👍

Synapse 1.59.0rc1 (2022-05-10) ============================== This release makes several changes that server administrators should be aware of: - Device name lookup over federation is now disabled by default. ([\#12616](#12616)) - The `synapse.app.appservice` and `synapse.app.user_dir` worker application types are now deprecated. ([\#12452](#12452), [\#12654](#12654)) See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1590) for more details. Additionally, this release removes the non-standard `m.login.jwt` login type from Synapse. It can be replaced with `org.matrix.login.jwt` for identical behaviour. This is only used if `jwt_config.enabled` is set to `true` in the configuration. ([\#12597](#12597)) Features -------- - Support [MSC3266](matrix-org/matrix-spec-proposals#3266) room summaries over federation. ([\#11507](#11507)) - Implement [changes](matrix-org/matrix-spec-proposals@4a77139) to [MSC2285 (hidden read receipts)](matrix-org/matrix-spec-proposals#2285). Contributed by @SimonBrandner. ([\#12168](#12168), [\#12635](#12635), [\#12636](#12636), [\#12670](#12670)) - Extend the [module API](https://github.com/matrix-org/synapse/blob/release-v1.59/synapse/module_api/__init__.py) to allow modules to change actions for existing push rules of local users. ([\#12406](#12406)) - Add the `notify_appservices_from_worker` configuration option (superseding `notify_appservices`) to allow a generic worker to be designated as the worker to send traffic to Application Services. ([\#12452](#12452)) - Add the `update_user_directory_from_worker` configuration option (superseding `update_user_directory`) to allow a generic worker to be designated as the worker to update the user directory. ([\#12654](#12654)) - Add new `enable_registration_token_3pid_bypass` configuration option to allow registrations via token as an alternative to verifying a 3pid. ([\#12526](#12526)) - Implement [MSC3786](matrix-org/matrix-spec-proposals#3786): Add a default push rule to ignore `m.room.server_acl` events. ([\#12601](#12601)) - Add new `mau_appservice_trial_days` configuration option to specify a different trial period for users registered via an appservice. ([\#12619](#12619)) Bugfixes -------- - Fix a bug introduced in Synapse 1.48.0 where the latest thread reply provided failed to include the proper bundled aggregations. ([\#12273](#12273)) - Fix a bug introduced in Synapse 1.22.0 where attempting to send a large amount of read receipts to an application service all at once would result in duplicate content and abnormally high memory usage. Contributed by Brad & Nick @ Beeper. ([\#12544](#12544)) - Fix a bug introduced in Synapse 1.57.0 which could cause `Failed to calculate hosts in room` errors to be logged for outbound federation. ([\#12570](#12570)) - Fix a long-standing bug where status codes would almost always get logged as `200!`, irrespective of the actual status code, when clients disconnect before a request has finished processing. ([\#12580](#12580)) - Fix race when persisting an event and deleting a room that could lead to outbound federation breaking. ([\#12594](#12594)) - Fix a bug introduced in Synapse 1.53.0 where bundled aggregations for annotations/edits were incorrectly calculated. ([\#12633](#12633)) - Fix a long-standing bug where rooms containing power levels with string values could not be upgraded. ([\#12657](#12657)) - Prevent memory leak from reoccurring when presence is disabled. ([\#12656](#12656)) Updates to the Docker image --------------------------- - Explicitly opt-in to using [BuildKit-specific features](https://github.com/moby/buildkit/blob/master/frontend/dockerfile/docs/syntax.md) in the Dockerfile. This fixes issues with building images in some GitLab CI environments. ([\#12541](#12541)) - Update the "Build docker images" GitHub Actions workflow to use `docker/metadata-action` to generate docker image tags, instead of a custom shell script. Contributed by @henryclw. ([\#12573](#12573)) Improved Documentation ---------------------- - Update SQL statements and replace use of old table `user_stats_historical` in docs for Synapse Admins. ([\#12536](#12536)) - Add missing linebreak to `pipx` install instructions. ([\#12579](#12579)) - Add information about the TCP replication module to docs. ([\#12621](#12621)) - Fixes to the formatting of `README.rst`. ([\#12627](#12627)) - Fix docs on how to run specific Complement tests using the `complement.sh` test runner. ([\#12664](#12664)) Deprecations and Removals ------------------------- - Remove unstable identifiers from [MSC3069](matrix-org/matrix-spec-proposals#3069). ([\#12596](#12596)) - Remove the unspecified `m.login.jwt` login type and the unstable `uk.half-shot.msc2778.login.application_service` from [MSC2778](matrix-org/matrix-spec-proposals#2778). ([\#12597](#12597)) - Synapse now requires at least Python 3.7.1 (up from 3.7.0), for compatibility with the latest Twisted trunk. ([\#12613](#12613)) Internal Changes ---------------- - Use supervisord to supervise Postgres and Caddy in the Complement image to reduce restart time. ([\#12480](#12480)) - Immediately retry any requests that have backed off when a server comes back online. ([\#12500](#12500)) - Use `make_awaitable` instead of `defer.succeed` for return values of mocks in tests. ([\#12505](#12505)) - Consistently check if an object is a `frozendict`. ([\#12564](#12564)) - Protect module callbacks with read semantics against cancellation. ([\#12568](#12568)) - Improve comments and error messages around access tokens. ([\#12577](#12577)) - Improve docstrings for the receipts store. ([\#12581](#12581)) - Use constants for read-receipts in tests. ([\#12582](#12582)) - Log status code of cancelled requests as 499 and avoid logging stack traces for them. ([\#12587](#12587), [\#12663](#12663)) - Remove special-case for `twisted` logger from default log config. ([\#12589](#12589)) - Use `getClientAddress` instead of the deprecated `getClientIP`. ([\#12599](#12599)) - Add link to documentation in Grafana Dashboard. ([\#12602](#12602)) - Reduce log spam when running multiple event persisters. ([\#12610](#12610)) - Add extra debug logging to federation sender. ([\#12614](#12614)) - Prevent remote homeservers from requesting local user device names by default. ([\#12616](#12616)) - Add a consistency check on events which we read from the database. ([\#12620](#12620)) - Remove use of the `constantly` library and switch to enums for `EventRedactBehaviour`. Contributed by @andrewdoh. ([\#12624](#12624)) - Remove unused code related to receipts. ([\#12632](#12632)) - Minor improvements to the scripts for running Synapse in worker mode under Complement. ([\#12637](#12637)) - Move `pympler` back in to the `all` extras. ([\#12652](#12652)) - Fix spelling of `M_UNRECOGNIZED` in comments. ([\#12665](#12665)) - Release script: confirm the commit to be tagged before tagging. ([\#12556](#12556)) - Fix a typo in the announcement text generated by the Synapse release development script. ([\#12612](#12612)) - Fix scripts-dev to pass typechecking. ([\#12356](#12356)) - Add some type hints to datastore. ([\#12485](#12485)) - Remove unused `# type: ignore`s.

We were sometimes checking
isinstance(foo, (dict, frozendict))and other times we were checkingisinstance(foo, collections.abc.Mapping).
