Slightly more involved than normal because it requires us to pass a backup version into OlmMachine.importBackedUpRoomKeys.
On the other hand we can now re-enable the test that was disabled in #4214 due to matrix-org/matrix-rust-sdk#3447Fixes: element-hq/element-web#27165
* Add `PerSessionKeyBackupDownloader.isKeyBackupDownloadConfigured()`
* Add new `RustBackupManager.getServerBackupInfo`
... and a convenience method in PerSessionKeyBackupDownloader to access it.
* Crypto.spec: move `useRealTimers` to global `afterEach`
... so that we don't need to remember to do it everywhere.
* Use fake timers for UTD error code tests
This doesn't have any effect on the tests, but *does* stop jest from hanging
when you run the tests in in-band mode. It shouldn't *really* be needed, but
using fake timers gives more reproducible tests, and I don't have the
time/patience to debug why it is needed.
* Use new error codes for UTDs from historical events
* initial commit
* new interation test
* more comments
* fix test, quick refactor on request version
* cleaning and logs
* fix type
* cleaning
* remove delegate stuff
* remove events and use timer mocks
* fix import
* ts ignore in tests
* Quick cleaning
* code review
* Use Errors instead of Results
* cleaning
* review
* remove forceCheck as not useful
* bad naming
* inline pauseLoop
* mark as paused in finally
* code review
* post merge fix
* rename KeyDownloadRateLimit
* use same config in loop and pass along
