* Remove unnecessary reactor reference from `_PerHostRatelimiter` (#14842)Sean Quah2023-01-161-8/+2
| | | | | Fix up #14812 to avoid introducing a reference to the reactor. Signed-off-by: Sean Quah <seanq@matrix.org>
* Fix stack overflow in `_PerHostRatelimiter` due to synchronous requests (#14812)Sean Quah2023-01-131-9/+25
| | | | | | | | | | | | | | | | | | When there are many synchronous requests waiting on a `_PerHostRatelimiter`, each request will be started recursively just after the previous request has completed. Under the right conditions, this leads to stack exhaustion. A common way for requests to become synchronous is when the remote client disconnects early, because the homeserver is overloaded and slow to respond. Avoid stack exhaustion under these conditions by deferring subsequent requests until the next reactor tick. Fixes #14480. Signed-off-by: Sean Quah <seanq@matrix.org>

| | | | | | | PKCE can protect against certain attacks and is enabled by default. Support can be controlled manually by setting the pkce_method of each oidc_providers entry to 'auto' (default), 'always', or 'never'. This is required by Twitter OAuth 2.0 support.

* Respond with proper error responses on unknown paths. (#14621)Patrick Cloke2022-12-081-2/+4
| | | | Returns a proper 404 with an errcode of M_RECOGNIZED for unknown endpoints per MSC3743.
* Check the stream position before checking if the cache is empty. (#14639)Patrick Cloke2022-12-081-4/+5
| | | | | | An empty cache does not mean the entity has no changed, if it is earlier than the earliest known stream position return that the entity *has* changed since the cache cannot accurately answer that query.
* Better return type for `get_all_entities_changed` (#14604)Erik Johnston2022-12-051-15/+37
| | | | Help callers from using the return value incorrectly by ensuring that callers explicitly check if there was a cache hit or not.
* Compare to the earliest known stream pos in the stream change cache. (#14435)Patrick Cloke2022-12-051-26/+116
| | | | | | The internal methods of the StreamChangeCache were inconsistently treating the earliest known stream position as valid. It is now treated as invalid, meaning the cache cannot determine if an entity at the earliest known stream position has changed or not.
* Batch fetch bundled annotations (#14491)Patrick Cloke2022-11-221-1/+1
| | | | | | | | Avoid an n+1 query problem and fetch the bundled aggregations for m.annotation relations in a single query instead of a query per event. This applies similar logic for as was previously done for edits in 8b309adb436c162510ed1402f33b8741d71fc058 (#11660) and threads in b65acead428653b988351ae8d7b22127a22039cd (#11752).
* Remove redundant types from comments. (#14412)Patrick Cloke2022-11-169-16/+18
| | | | | | | Remove type hints from comments which have been added as Python type hints. This helps avoid drift between comments and reality, as well as removing redundant information. Also adds some missing type hints which were simple to fill in.
* Remove duplicated code to evict entries. (#14410)Patrick Cloke2022-11-101-9/+2
| | | | | | | | This code was factored out to a method, but also left in-place. Calling this twice in a row makes no sense: the first call will reduce the size appropriately, but the loop will immediately exit since the cache size was already reduced.

* Fix `have_seen_event` cache not being invalidated (#13863)Eric Eastwood2022-09-271-0/+6
| | | | | | | | | | | | | | | | | | | | | Fix https://github.com/matrix-org/synapse/issues/13856 Fix https://github.com/matrix-org/synapse/issues/13865 > Discovered while trying to make Synapse fast enough for [this MSC2716 test for importing many batches](https://github.com/matrix-org/complement/pull/214#discussion_r741678240). As an example, disabling the `have_seen_event` cache saves 10 seconds for each `/messages` request in that MSC2716 Complement test because we're not making as many federation requests for `/state` (speeding up `have_seen_event` itself is related to https://github.com/matrix-org/synapse/issues/13625) > > But this will also make `/messages` faster in general so we can include it in the [faster `/messages` milestone](https://github.com/matrix-org/synapse/milestone/11). > > *-- https://github.com/matrix-org/synapse/issues/13856* ### The problem `_invalidate_caches_for_event` doesn't run in monolith mode which means we never even tried to clear the `have_seen_event` and other caches. And even in worker mode, it only runs on the workers, not the master (AFAICT). Additionally there was bug with the key being wrong so `_invalidate_caches_for_event` never invalidates the `have_seen_event` cache even when it does run. Because we were using the `@cachedList` wrong, it was putting items in the cache under keys like `((room_id, event_id),)` with a `set` in a `set` (ex. `(('!TnCIJPKzdQdUlIyXdQ:test', '$Iu0eqEBN7qcyF1S9B3oNB3I91v2o5YOgRNPwi_78s-k'),)`) and we we're trying to invalidate with just `(room_id, event_id)` which did nothing.

| | | | | | | | | | | | | | | | | | This speeds things up by ~2x. The vast majority of the time is now spent in `LruCache` moving things around the linked lists. We do this via two things: 1. Don't create a deferred per-key during bulk set operations in `DeferredCache`. Instead, only create them if a subsequent caller asks for the key. 2. Add a bulk lookup API to `DeferredCache` rather than use a loop.

* Optimise async get event lookups (#13435)Nick Mills-Barrett2022-08-041-0/+17
| | | | | | Still maintains local in memory lookup optimisation, but does any external lookup as part of the deferred that prevents duplicate lookups for the same event at once. This makes the assumption that fetching from an external cache is a non-zero load operation.

* Move the "email unsubscribe" resource, refactor the macaroon generator & ↵Quentin Gliech2022-06-141-0/+308
| | | | | | | | | | | | | | | | | | | | | simplify the access token verification logic. (#12986) This simplifies the access token verification logic by removing the `rights` parameter which was only ever used for the unsubscribe link in email notifications. The latter has been moved under the `/_synapse` namespace, since it is not a standard API. This also makes the email verification link more secure, by embedding the app_id and pushkey in the macaroon and verifying it. This prevents the user from tampering the query parameters of that unsubscribe link. Macaroon generation is refactored: - Centralised all macaroon generation and verification logic to the `MacaroonGenerator` - Moved to `synapse.utils` - Changed the constructor to require only a `Clock`, hostname, and a secret key (instead of a full `Homeserver`). - Added tests for all methods.

* Remove unused `# type: ignore`s (#12531)David Robertson2022-04-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | Over time we've begun to use newer versions of mypy, typeshed, stub packages---and of course we've improved our own annotations. This makes some type ignore comments no longer necessary. I have removed them. There was one exception: a module that imports `select.epoll`. The ignore is redundant on Linux, but I've kept it ignored for those of us who work on the source tree using not-Linux. (#11771) I'm more interested in the config line which enforces this. I want unused ignores to be reported, because I think it's useful feedback when annotating to know when you've fixed a problem you had to previously ignore. * Installing extras before typechecking Lacking an easy way to install all extras generically, let's bite the bullet and make install the hand-maintained `all` extra before typechecking.

* Fix `LruCache` corruption bug with a `size_callback` that can return 0 (#11454)Sean Quah2021-11-301-1/+4
| | | | | | | | | | | When all entries in an `LruCache` have a size of 0 according to the provided `size_callback`, and `drop_from_cache` is called on a cache node, the node would be unlinked from the LRU linked list but remain in the cache dictionary. An assertion would be later be tripped due to the inconsistency. Avoid unintentionally calling `__len__` and use a strict `is None` check instead when unwrapping the weak reference.

See http://mypy-lang.blogspot.com/2021/06/mypy-0900-released.html for details. We therefore pull in stub packages in setup.py Additionally, some modules that we were previously ignoring import failures for now have stubs. So let's use them. The rest of this change consists of fixups to make the newer mypy + stubs pass CI. Co-authored-by: Patrick Cloke <clokep@users.noreply.github.com>
* Fix long-standing bug where `ReadWriteLock` could drop logging contexts (#10993)Sean Quah2021-10-081-2/+4
| | | | | | | | | | | Use `PreserveLoggingContext()` to ensure that logging contexts are not lost when exiting a read/write lock. When exiting a read/write lock, callbacks on a `Deferred` are triggered as a signal to any waiting coroutines. Any waiting coroutine that becomes runnable is likely to follow the Synapse logging context rules and will restore its own logging context, then either run to completion or await another `Deferred`, resetting the logging context in the process.

* Encode JSON responses on a thread in C, mk2 (#10905)Erik Johnston2021-09-281-2/+17
| | | | | | | | | | Currently we use `JsonEncoder.iterencode` to write JSON responses, which ensures that we don't block the main reactor thread when encoding huge objects. The downside to this is that `iterencode` falls back to using a pure Python encoder that is *much* less efficient and can easily burn a lot of CPU for huge responses. To fix this, while still ensuring we don't block the reactor loop, we encode the JSON on a threadpool using the standard `JsonEncoder.encode` functions, which is backed by a C library. Doing so, however, requires `respond_with_json` to have access to the reactor, which it previously didn't. There are two ways of doing this: 1. threading through the reactor object, which is a bit fiddly as e.g. `DirectServeJsonResource` doesn't currently take a reactor, but is exposed to modules and so is a PITA to change; or 2. expose the reactor in `SynapseRequest`, which requires updating a bunch of servlet types. I went with the latter as that is just a mechanical change, and I think makes sense as a request already has a reactor associated with it (via its http channel).

| | | | | | | | | | As far as I can tell our logging contexts are meant to log the request ID, or sometimes the request ID followed by a suffix (this is generally stored in the name field of LoggingContext).

For sub-contexts (created via nested_logging_contexts, defer_to_threadpool, Measure) we use the current context's str (which becomes their name or the string "sentinel") and then potentially modify that (e.g. add a suffix).

* Fix #8518 (sync requests being cached wrongly on timeout) (#9358)Jonathan de Jong2021-02-241-2/+32
| | | | | | | This fixes #8518 by adding a conditional check on `SyncResult` in a function when `prev_stream_token == current_stream_token`, as a sanity check. In `CachedResponse.set.<remove>()`, the result is immediately popped from the cache if the conditional function returns "false". This prevents the caching of a timed-out `SyncResult` (that has `next_key` as the stream key that produced that `SyncResult`). The cache is prevented from returning a `SyncResult` that makes the client request the same stream key over and over again, effectively making it stuck in a loop of requesting and getting a response immediately for as long as the cache keeps those values.

* Fix handling of connection timeouts in outgoing http requests (#8400)Richard van der Hoff2020-09-291-29/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove `on_timeout_cancel` from `timeout_deferred` The `on_timeout_cancel` param to `timeout_deferred` wasn't always called on a timeout (in particular if the canceller raised an exception), so it was unreliable. It was also only used in one place, and to be honest it's easier to do what it does a different way. * Fix handling of connection timeouts in outgoing http requests Turns out that if we get a timeout during connection, then a different exception is raised, which wasn't always handled correctly. To fix it, catch the exception in SimpleHttpClient and turn it into a RequestTimedOutError (which is already a documented exception). Also add a description to RequestTimedOutError so that we can see which stage it failed at. * Fix incorrect handling of timeouts reading federation responses This was trapping the wrong sort of TimeoutError, so was never being hit. The effect was relatively minor, but we should fix this so that it does the expected thing. * Fix inconsistent handling of `timeout` param between methods `get_json`, `put_json` and `delete_json` were applying a different timeout to the response body to `post_json`; bring them in line and test.

* re-implement daemonize (#8011)Richard van der Hoff2020-08-041-0/+131
| | | | | | | | | | | | | This has long been something I've wanted to do. Basically the `Daemonize` code is both too flexible and not flexible enough, in that it offers a bunch of features that we don't use (changing UID, closing FDs in the child, logging to syslog) and doesn't offer a bunch that we could do with (redirecting stdout/err to a file instead of /dev/null; having the parent not exit until the child is running). As a first step, I've lifted the Daemonize code and removed the bits we don't use. This should be a non-functional change. Fixing everything else will come later.

* Extend StreamChangeCache to support multiple entities per stream ID (#7303)Richard van der Hoff2020-04-221-46/+71
| | | | | | | | | | | | | | | | | | | First some background: StreamChangeCache is used to keep track of what "entities" have changed since a given stream ID. So for example, we might use it to keep track of when the last to-device message for a given user was received [1], and hence whether we need to pull any to-device messages from the database on a sync [2]. Now, it turns out that StreamChangeCache didn't support more than one thing being changed at a given stream_id (this was part of the problem with #7206). However, it's entirely valid to send to-device messages to more than one user at a time. As it turns out, this did in fact work, because *some* methods of StreamChangeCache coped ok with having multiple things changing on the same stream ID, and it seems we never actually use the methods which don't work on the stream change caches where we allow multiple changes at the same stream ID. But that feels horribly fragile, hence: let's update StreamChangeCache to properly support this, and add some typing and some more tests while we're at it. [1]: https://github.com/matrix-org/synapse/blob/release-v1.12.3/synapse/storage/data_stores/main/deviceinbox.py#L301 [2]: https://github.com/matrix-org/synapse/blob/release-v1.12.3/synapse/storage/data_stores/main/deviceinbox.py#L47-L51
* On catchup, process each row with its own stream id (#7286)Richard van der Hoff2020-04-201-0/+3
| | | | | | Other parts of the code (such as the StreamChangeCache) assume that there will not be multiple changes with the same stream id. This code was introduced in #7024, and I hope this fixes #7206.
* Rewrite prune_old_outbound_device_pokes for efficiency (#7159)Richard van der Hoff2020-03-301-1/+20

* Clean up some LoggingContext stuff (#7120)Richard van der Hoff2020-03-242-20/+20
| | | | | | | | | | | | | | | | | | | | | | | * Pull Sentinel out of LoggingContext ... and drop a few unnecessary references to it * Factor out LoggingContext.current_context move `current_context` and `set_context` out to top-level functions. Mostly this means that I can more easily trace what's actually referring to LoggingContext, but I think it's generally neater. * move copy-to-parent into `stop` this really just makes `start` and `stop` more symetric. It also means that it behaves correctly if you manually `set_log_context` rather than using the context manager. * Replace `LoggingContext.alive` with `finished` Turn `alive` into `finished` and make it a bit better defined.
* Clarify list/set/dict/tuple comprehensions and enforce via flake8 (#6957)Patrick Cloke2020-02-211-1/+1
