I'm working on adding a new variant of R30.

This PR first characterises the current behaviour of the current R30 metric, by adding unit tests.

# Override the retention time for the user_ips table because otherwise it
# gets pruned too aggressively for our R30 test.

Does this mean that R30 doesn't work out of the box?

The default is 28d, so out of the box, it does seem like it's slightly broken, yes...

Out of the box, it can only count users who had activity in the last 28 days, where that activity occurred at least 30 days after registration.

The intention would be to count users who had activity in the last 30 days, where that activity occurred at least 30 days after registration, so it's not a MASSIVE difference.

I'm just wary of testing a feature by first changing the default config? Can we update the test to work with the default, or do we need to update the default?

In my opinion, the default should be changed. (However, I'm not sure how worthwhile that is since the idea is to add R30v2 and eventually remove R30 [I expect]...).
Updating the test to work with the default wouldn't really show what R30 actually means, it'd instead be R28 or something ;p.
I was hoping to basically just add a test to characterise the current behaviour and wasn't intending to change anything, though...

Suppose I could make a copy of the test that uses the default settings? What do you think is preferable?

Yeah, I guess its fair to merge as is.

Actually, yes, I think we should have a test for the default, since this is for phone home stats.

Can you make an issue for the whole R30 vs 28 days thing?

Synapse 1.39.0rc1 (2021-07-20)
==============================

The Third-Party Event Rules module interface has been deprecated in favour of the generic module interface introduced in Synapse v1.37.0. Support for the old interface is planned to be removed in September 2021. See the [upgrade notes](https://matrix-org.github.io/synapse/latest/upgrade.html#upgrading-to-v1390) for more information.

Features
--------

- Add the ability to override the account validity feature with a module. ([\#9884](#9884))
- The spaces summary API now returns any joinable rooms, not only rooms which are world-readable. ([\#10298](#10298), [\#10305](#10305))
- Add a new version of the R30 phone-home metric, which removes a false impression of retention given by the old R30 metric. ([\#10332](#10332), [\#10427](#10427))
- Allow providing credentials to `http_proxy`. ([\#10360](#10360))

Bugfixes
--------

- Fix error while dropping locks on shutdown. Introduced in v1.38.0. ([\#10433](#10433))
- Add base starting insertion event when no chunk ID is specified in the historical batch send API. ([\#10250](#10250))
- Fix historical batch send endpoint (MSC2716) rejecting batches with messages from multiple senders. ([\#10276](#10276))
- Fix purging rooms that other homeservers are still sending events for. Contributed by @ilmari. ([\#10317](#10317))
- Fix errors during backfill caused by previously purged redaction events. Contributed by Andreas Rammhold (@andir). ([\#10343](#10343))
- Fix the user directory becoming broken (and noisy errors being logged) when knocking and room statistics are in use. ([\#10344](#10344))
- Fix newly added `synapse_federation_server_oldest_inbound_pdu_in_staging` prometheus metric to measure age rather than timestamp. ([\#10355](#10355))
- Fix PostgreSQL sometimes using table scans for queries against `state_groups_state` table, taking a long time and a large amount of IO. ([\#10359](#10359))
- Fix `make_room_admin` failing for users that have left a private room. ([\#10367](#10367))
- Fix a number of logged errors caused by remote servers being down. ([\#10400](#10400), [\#10414](#10414))
- Responses from `/make_{join,leave,knock}` no longer include signatures, which will turn out to be invalid after events are returned to `/send_{join,leave,knock}`. ([\#10404](#10404))

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

- Updated installation dependencies for newer macOS versions and ARM Macs. Contributed by Luke Walsh. ([\#9971](#9971))
- Simplify structure of room admin API. ([\#10313](#10313))
- Refresh the logcontext dev documentation. ([\#10353](#10353)), ([\#10337](#10337))
- Add delegation example for caddy in the reverse proxy documentation. Contributed by @moritzdietz. ([\#10368](#10368))
- Fix and clarify some links in `docs` and `contrib`. ([\#10370](#10370)), ([\#10322](#10322)), ([\#10399](#10399))
- Make deprecation notice of the spam checker doc more obvious. ([\#10395](#10395))
- Add instructions on installing Debian packages for release candidates. ([\#10396](#10396))

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

- Remove functionality associated with the unused `room_stats_historical` and `user_stats_historical` tables. Contributed by @xmunoz. ([\#9721](#9721))
- The third-party event rules module interface is deprecated in favour of the generic module interface introduced in Synapse v1.37.0. See the [upgrade notes](https://matrix-org.github.io/synapse/latest/upgrade.html#upgrading-to-v1390) for more information. ([\#10386](#10386))

Internal Changes
----------------

- Convert `room_depth.min_depth` column to a `BIGINT`. ([\#10289](#10289))
- Add tests to characterise the current behaviour of R30 phone-home metrics. ([\#10315](#10315))
- Rebuild event context and auth when processing specific results from `ThirdPartyEventRules` modules. ([\#10316](#10316))
- Minor change to the code that populates `user_daily_visits`. ([\#10324](#10324))
- Re-enable Sytests that were disabled for the 1.37.1 release. ([\#10345](#10345), [\#10357](#10357))

Support for the old interface is planned to be removed in September 2021. See the [upgrade notes](https://matrix-org.github.io/synapse/latest/upgrade.html#upgrading-to-v1390) for more information.

Features
--------

- Add the ability to override the account validity feature with a module. ([\#9884](matrix-org/synapse#9884))
- The spaces summary API now returns any joinable rooms, not only rooms which are world-readable. ([\#10298](matrix-org/synapse#10298), [\#10305](matrix-org/synapse#10305))
- Add a new version of the R30 phone-home metric, which removes a false impression of retention given by the old R30 metric. ([\#10332](matrix-org/synapse#10332), [\#10427](matrix-org/synapse#10427))
- Allow providing credentials to `http_proxy`. ([\#10360](matrix-org/synapse#10360))

Bugfixes
--------

- Fix error while dropping locks on shutdown. Introduced in v1.38.0. ([\#10433](matrix-org/synapse#10433))
- Add base starting insertion event when no chunk ID is specified in the historical batch send API. ([\#10250](matrix-org/synapse#10250))
- Fix historical batch send endpoint (MSC2716) rejecting batches with messages from multiple senders. ([\#10276](matrix-org/synapse#10276))
- Fix purging rooms that other homeservers are still sending events for. Contributed by @ilmari. ([\#10317](matrix-org/synapse#10317))
- Fix errors during backfill caused by previously purged redaction events. Contributed by Andreas Rammhold (@andir). ([\#10343](matrix-org/synapse#10343))
- Fix the user directory becoming broken (and noisy errors being logged) when knocking and room statistics are in use. ([\#10344](matrix-org/synapse#10344))
- Fix newly added `synapse_federation_server_oldest_inbound_pdu_in_staging` prometheus metric to measure age rather than timestamp. ([\#10355](matrix-org/synapse#10355))
- Fix PostgreSQL sometimes using table scans for queries against `state_groups_state` table, taking a long time and a large amount of IO. ([\#10359](matrix-org/synapse#10359))
- Fix `make_room_admin` failing for users that have left a private room. ([\#10367](matrix-org/synapse#10367))
- Fix a number of logged errors caused by remote servers being down. ([\#10400](matrix-org/synapse#10400), [\#10414](matrix-org/synapse#10414))
- Responses from `/make_{join,leave,knock}` no longer include signatures, which will turn out to be invalid after events are returned to `/send_{join,leave,knock}`. ([\#10404](matrix-org/synapse#10404))

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

- Updated installation dependencies for newer macOS versions and ARM Macs. Contributed by Luke Walsh. ([\#9971](matrix-org/synapse#9971))
- Simplify structure of room admin API. ([\#10313](matrix-org/synapse#10313))
- Refresh the logcontext dev documentation. ([\#10353](matrix-org/synapse#10353)), ([\#10337](matrix-org/synapse#10337))
- Add delegation example for caddy in the reverse proxy documentation. Contributed by @moritzdietz. ([\#10368](matrix-org/synapse#10368))
- Fix and clarify some links in `docs` and `contrib`. ([\#10370](matrix-org/synapse#10370)), ([\#10322](matrix-org/synapse#10322)), ([\#10399](matrix-org/synapse#10399))
- Make deprecation notice of the spam checker doc more obvious. ([\#10395](matrix-org/synapse#10395))
- Add instructions on installing Debian packages for release candidates. ([\#10396](matrix-org/synapse#10396))

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

- Remove functionality associated with the unused `room_stats_historical` and `user_stats_historical` tables. Contributed by @xmunoz. ([\#9721](matrix-org/synapse#9721))
- The third-party event rules module interface is deprecated in favour of the generic module interface introduced in Synapse v1.37.0. See the [upgrade notes](https://matrix-org.github.io/synapse/latest/upgrade.html#upgrading-to-v1390) for more information. ([\#10386](matrix-org/synapse#10386))

Internal Changes
----------------

- Convert `room_depth.min_depth` column to a `BIGINT`. ([\#10289](matrix-org/synapse#10289))
- Add tests to characterise the current behaviour of R30 phone-home metrics. ([\#10315](matrix-org/synapse#10315))
- Rebuild event context and auth when processing specific results from `ThirdPartyEventRules` modules. ([\#10316](matrix-org/synapse#10316))
- Minor change to the code that populates `user_daily_visits`. ([\#10324](matrix-org/synapse#10324))
- Re-enable Sytests that were disabled for the 1.37.1 release. ([\#10345](matrix-org/synapse#10345), [\#10357](matrix-org/synapse#10357))
- Run `pyupgrade` on the codebase. ([\#10347](matrix-org/synapse#10347), [\#10348](matrix-org/synapse#10348))
- Switch `application_services_txns.txn_id` database column to `BIGINT`. ([\#10349](matrix-org/synapse#10349))
- Convert internal type variable syntax to reflect wider ecosystem use. ([\#10350](matrix-org/synapse#10350), [\#10380](matrix-org/synapse#10380), [\#10381](matrix-org/synapse#10381), [\#10382](matrix-org/synapse#10382), [\#10418](matrix-org/synapse#10418))
