| * | Improve exception handling for background processesRichard van der Hoff2018-04-271-1/+6
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were a bunch of places where we fire off a process to happen in the background, but don't have any exception handling on it - instead relying on the unhandled error being logged when the relevent deferred gets garbage-collected. This is unsatisfactory for a number of reasons: - logging on garbage collection is best-effort and may happen some time after the error, if at all - it can be hard to figure out where the error actually happened. - it is logged as a scary CRITICAL error which (a) I always forget to grep for and (b) it's not really CRITICAL if a background process we don't care about fails. So this is an attempt to add exception handling to everything we fire off into the background.

|\ \ | |/ |/| Refactor ResponseCache usage
| * ResponseCache: fix handling of completed resultsRichard van der Hoff2018-04-131-13/+19
| | | | | | | | | | Turns out that ObservableDeferred.observe doesn't return a deferred if the result is already completed. Fix handling and improve documentation.
| * Refactor ResponseCache usageRichard van der Hoff2018-04-121-2/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds a `.wrap` method to ResponseCache which wraps up the boilerplate of a (get, set) pair, and then use it throughout the codebase. This will be largely non-functional, but does include the following functional changes: * federation_server.on_context_state_request: drops use of _server_linearizer which looked redundant and could cause incorrect cache misses by yielding between the get and the set. * RoomListHandler.get_remote_public_room_list(): fixes logcontext leaks * the wrap function includes some logging. I'm hoping this won't be too noisy on production.
* | Revert "Use sortedcontainers instead of blist"Richard van der Hoff2018-04-131-2/+2
|/ | | | | | | | | | | This reverts commit 9fbe70a7dc3afabfdac176ba1f4be32dd44602aa. It turns out that sortedcontainers.SortedDict is not an exact match for blist.sorteddict; in particular, `popitem()` removes things from the opposite end of the dict. This is trivial to fix, but I want to add some unit tests, and potentially some more thought about it, before we do so.

* Fix bug where state cache used lots of memoryErik Johnston2018-03-152-5/+9
| | | | | | | | | The state cache bases its size on the sum of the size of entries. The size of the entry is calculated once on insertion, so it is important that the size of entries does not change. The DictionaryCache modified the entries size, which caused the state cache to incorrectly think it was smaller than it actually was.

* Make get_state_groups_from_groups faster.Erik Johnston2017-05-171-11/+46
| | | | | | | | | Most of the time was spent copying a dict to filter out sentinel values that indicated that keys did not exist in the dict. The sentinel values were added to ensure that we cached the non-existence of keys. By updating DictionaryCache to keep track of which keys were known to not exist itself we can remove a dictionary copy.

* Reduce size of joined_user cacheErik Johnston2017-04-251-0/+14
| | | | | | | | The _get_joined_users_from_context cache stores a mapping from user_id to avatar_url and display_name. Instead of storing those in a dict, store them in a namedtuple as that uses much less memory. We also try converting the string to ascii to further reduce the size.
* Remove DEBUG_CACHESErik Johnston2017-04-251-2/+0
|
* Reduce cache size by not storing deferredsErik Johnston2017-04-251-18/+21
| | | | | | | | | | | | | | | | | | | | Currently the cache descriptors store deferreds rather than raw values, this is a simple way of triggering only one database hit and sharing the result if two callers attempt to get the same value. However, there are a few caches that simply store a mapping from string to string (or int). These caches can have a large number of entries, under the assumption that each entry is small. However, the size of a deferred (specifically the size of ObservableDeferred) is signigicantly larger than that of the raw value, 2kb vs 32b. This PR therefore changes the cache descriptors to store the raw values rather than the deferreds. As a side effect cached storage function now either return a deferred or the actual value, as the cached list decriptor already does. This is fine as we always end up just yield'ing on the returned value eventually, which handles that case correctly.

* Speed up cache size calculationErik Johnston2017-01-175-46/+128
| | | | | | | | | | | Instead of calculating the size of the cache repeatedly, which can take a long time now that it can use a callback, instead cache the size and update that on insertion and deletion. This requires changing the cache descriptors to have two caches, one for pending deferreds and the other for the actual values. There's no reason to evict from the pending deferreds as they won't take up any more memory.

* Remove full_twisted_stacktraces optionErik Johnston2017-01-121-71/+0
| | | | | | | | | | | | | | | | | The debug 'full_twisted_stacktraces' flag caused synapse to rewrite twisted deferreds to always fire the callback on the next reactor tick. This was to force the deferred to always store the stacktraces on exceptions, and thus be more likely to have a full stacktrace when it reaches the final error handlers and gets printed to the logs. Dynamically rewriting things is generally bad, and in particular this change violates assumptions of various bits of Twisted. This wouldn't necessarily be so bad, but it turns out this option has been turned on on some production servers. Turning the option can cause e.g. #1778. For now, lets just entirely nuke this option.

| | | | | | | | | | The only place that was observed was to set the profile. I've made it so that the profile is set within store.register in the same transaction that creates the user. This required some slight changes to the registration code for upgrading guest users, since it previously relied on the distributor swallowing errors if the profile already existed.
