This patch renames the `LockStoreError` enum to `CrossProcessLockError`
to be consistent with the other types in the same module.
The `BackingStoreError` variant is also renamed to `TryLockError`.
This patch renames `check_tombstone` to `check_room_upgrades`.
Then it rewrites it **entirely** to remove all false-positives and
false-negatives. More importantly, the room versions are no longer
involved: they can't be compared or ordered, they must be treated as
opaque values.
This new version of `check_room_upgrades` does a first path to check
predecessor-successor consistency. Then it does a second version to
detect loops. This new algorithm is robust to absent `m.room.create`
events. Making them mandatory is left to another patch.
More tests are added, especially to ensure that `m.room.create` cannot
be overwritten, and to ensure loops or inconsistent predecessors and
successors are correctly detected.
This patch adds the `check_tombstone` response processor to
detect invalid state with room upgrades. One can check the new
`InconsistentTombstonedRooms` error to learn more about the detected
patterns.
When all room members are loaded, we do not need an incremental member update. We know that parsing the /members response will only lead to more ambiguous names, not less. And because /members returns the complete list, we can directly use that list as the disambiguation map.
This improves the performance in my emulator from 56s to 9s and on a less performant device from 11mins to 11s (Tested experimentally on Matrix HQ using log statements in element android. If I have time, I will write a proper benchmark tomorrow.
