* Refactor state moduleErik Johnston2018-08-091-866/+0
| | | | | We split out the actual state resolution algorithm to prepare for having multiple versions.

* Fixes and optimisations for resolve_state_groupsRichard van der Hoff2018-07-231-54/+89
| | | | | | | | | | | | | | | | | | | | First of all, fix the logic which looks for identical input state groups so that we actually use them. This turned out to be most easily done by factoring the relevant code out to a separate function so that we could do an early return. Secondly, avoid building the whole `conflicted_state` dict (which was only ever used as a boolean flag). Thirdly, replace the construction of the `state` dict (which mapped from keys to events that set them), with an optimistic construction of the resolution result assuming there will be no conflicts. This should be no slower than building the old `state` dict, and: - in the conflicted case, we'll short-cut it, saving part of the work - in the unconflicted case, it saves rebuilding the resolution from the `state` dict. Finally, do a couple of s/values/itervalues/.

| | | | | | | | | | | | We extract the storage-independent bits of the state group resolution out to a separate functiom, and stick it in a new handler, in preparation for its use from the storage layer.
