This also removes a cache that is unlikely to ever get hit.
This makes it easier to document what is being returned by the storage functions and what some functions expect as arguments.
There is no reason to return a tuple of tokens when the last token is always the token passed as an argument. Changing it makes it consistent with other storage APIs
This allows calling the `get_recent_event_ids_for_room` function in more situations.
The sync API often returns events in a topological rather than stream ordering, e.g. when the user joined the room or on initial sync. When this happens we can reuse existing pagination storage functions.

I think it might be worth preserving this comment, but moving it to sync.py?

Looking at it I don't really know why we don't always use the topological ordering, but I've added the comment.

Changes in synapse v0.29.1 (2018-05-17) ========================================== Changes: * Update docker documentation (PR #3222) Changes in synapse v0.29.0 (2018-05-16) =========================================== Not changes since v0.29.0-rc1 Changes in synapse v0.29.0-rc1 (2018-05-14) =========================================== Notable changes, a docker file for running Synapse (Thanks to @kaiyou!) and a closed spec bug in the Client Server API. Additionally further prep for Python 3 migration. Potentially breaking change: * Make Client-Server API return 401 for invalid token (PR #3161). This changes the Client-server spec to return a 401 error code instead of 403 when the access token is unrecognised. This is the behaviour required by the specification, but some clients may be relying on the old, incorrect behaviour. Thanks to @NotAFile for fixing this. Features: * Add a Dockerfile for synapse (PR #2846) Thanks to @kaiyou! Changes - General: * nuke-room-from-db.sh: added postgresql option and help (PR #2337) Thanks to @rubo77! * Part user from rooms on account deactivate (PR #3201) * Make 'unexpected logging context' into warnings (PR #3007) * Set Server header in SynapseRequest (PR #3208) * remove duplicates from groups tables (PR #3129) * Improve exception handling for background processes (PR #3138) * Add missing consumeErrors to improve exception handling (PR #3139) * reraise exceptions more carefully (PR #3142) * Remove redundant call to preserve_fn (PR #3143) * Trap exceptions thrown within run_in_background (PR #3144) Changes - Refactors: * Refactor /context to reuse pagination storage functions (PR #3193) * Refactor recent events func to use pagination func (PR #3195) * Refactor pagination DB API to return concrete type (PR #3196) * Refactor get_recent_events_for_room return type (PR #3198) * Refactor sync APIs to reuse pagination API (PR #3199) * Remove unused code path from member change DB func (PR #3200) * Refactor request handling wrappers (PR #3203) * transaction_id, destination defined twice (PR #3209) Thanks to @damir-manapov! * Refactor event storage to prepare for changes in state calculations (PR #3141) * Set Server header in SynapseRequest (PR #3208) * Use deferred.addTimeout instead of time_bound_deferred (PR #3127, #3178) * Use run_in_background in preference to preserve_fn (PR #3140) Changes - Python 3 migration: * Construct HMAC as bytes on py3 (PR #3156) Thanks to @NotAFile! * run config tests on py3 (PR #3159) Thanks to @NotAFile! * Open certificate files as bytes (PR #3084) Thanks to @NotAFile! * Open config file in non-bytes mode (PR #3085) Thanks to @NotAFile! * Make event properties raise AttributeError instead (PR #3102) Thanks to @NotAFile! * Use six.moves.urlparse (PR #3108) Thanks to @NotAFile! * Add py3 tests to tox with folders that work (PR #3145) Thanks to @NotAFile! * Don't yield in list comprehensions (PR #3150) Thanks to @NotAFile! * Move more xrange to six (PR #3151) Thanks to @NotAFile! * make imports local (PR #3152) Thanks to @NotAFile! * move httplib import to six (PR #3153) Thanks to @NotAFile! * Replace stringIO imports with six (PR #3154, #3168) Thanks to @NotAFile! * more bytes strings (PR #3155) Thanks to @NotAFile! Bug Fixes: * synapse fails to start under Twisted >= 18.4 (PR #3157) * Fix a class of logcontext leaks (PR #3170) * Fix a couple of logcontext leaks in unit tests (PR #3172) * Fix logcontext leak in media repo (PR #3174) * Escape label values in prometheus metrics (PR #3175, #3186) * Fix 'Unhandled Error' logs with Twisted 18.4 (PR #3182) Thanks to @Half-Shot! * Fix logcontext leaks in rate limiter (PR #3183) * notifications: Convert next_token to string according to the spec (PR #3190) Thanks to @mujx! * nuke-room-from-db.sh: fix deletion from search table (PR #3194) Thanks to @rubo77! * add guard for None on purge_history api (PR #3160) Thanks to @krombel!
