There are two decorators on `send_request`: Prometheus' `Gauge.track_inprogress()` and Synapse's `opentracing.trace`. `Gauge.track_inprogress()` does not have any support for async functions when used as a decorator. Since async functions behave like regular functions that return coroutines, only the creation of the coroutine was covered by the metric and none of the actual body of `send_request`. `Gauge.track_inprogress()` returns a regular, non-async function wrapping `send_request`, which is the source of the next bug. The `opentracing.trace` decorator would normally handle async functions correctly, but since the wrapped `send_request` is a non-async function, the decorator ends up suffering from the same issue as `Gauge.track_inprogress()`: the opentracing span only measures the creation of the coroutine and none of the actual function body. Using `Gauge.track_inprogress()` as a context manager instead of a decorator resolves both bugs. --- changelog.d/10996.misc | 1 + synapse/logging/opentracing.py | 8 ++ synapse/replication/http/_base.py | 148 +++++++++++++++--------------- 3 files changed, 84 insertions(+), 73 deletions(-) create mode 100644 changelog.d/10996.misc diff --git a/changelog.d/10996.misc b/changelog.d/10996.misc new file mode 100644 index 000000000..c830d7ec2 --- /dev/null +++ b/changelog.d/10996.misc @@ -0,0 +1 @@ +Fix a bug introduced in Synapse 1.21.0 that causes opentracing and Prometheus metrics for replication requests to be measured incorrectly. diff --git a/synapse/logging/opentracing.py b/synapse/logging/opentracing.py index 5276c4bfc..20d23a426 100644 --- a/synapse/logging/opentracing.py +++ b/synapse/logging/opentracing.py @@ -807,6 +807,14 @@ def trace(func=None, opname=None): result.addCallbacks(call_back, err_back) else: + if inspect.isawaitable(result): + logger.error( + "@trace may not have wrapped %s correctly!

From 35d6b914eb98e218007b7977a85f5022d25072fb Mon Sep 17 00:00:00 2001 From: Eric Eastwood Date: Wed, 13 Oct 2021 17:44:00 -0500 Subject: [PATCH 17/72] Resolve and share `state_groups` for all historical events in batch (MSC2716) (#10975) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Resolve and share `state_groups` for all historical events in batch. This also helps for showing the appropriate avatar/displayname in Element and will work whenever `/messages` has one of the historical messages as the first message in the batch. This does have the flaw where if you just insert a single historical event somewhere, it probably won't resolve the state correctly from `/messages` or `/context` since it will grab a non historical event above or below with resolved state which never included the historical state back then. For the same reasions, this also does not work in Element between the transition from actual messages to historical messages. In the Gitter case, this isn't really a problem since all of the historical messages are in one big lump at the beginning of the room. For a future iteration, might be good to look at `/messages` and `/context` to additionally add the `state` for any historical messages in that batch. --- How are the `state_groups` shared? To illustrate the `state_group` sharing, see this example: **Before** (new `state_group` for every event 😬, very inefficient): ``` # Tests from https://github.com/matrix-org/complement/pull/206 $ COMPLEMENT_ALWAYS_PRINT_SERVER_LOGS=1 COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh TestBackfillingHistory/parallel/should_resolve_member_state_events_for_historical_events create_new_client_event m.room.member event=$_JXfwUDIWS6xKGG4SmZXjSFrizhARM7QblhATVWWUcA state_group=None create_new_client_event org.matrix.msc2716.insertion event=$1ZBfmBKEjg94d-vGYymKrVYeghwBOuGJ3wubU1-I9y0 state_group=9 create_new_client_event org.matrix.msc2716.insertion event=$Mq2JvRetTyclPuozRI682SAjYp3GqRuPc8_cH5-ezPY state_group=10 create_new_client_event m.room.message event=$MfmY4rBQkxrIp8jVwVMTJ4PKnxSigpG9E2cn7S0AtTo state_group=11 create_new_client_event m.room.message event=$uYOv6V8wiF7xHwOMt-60d1AoOIbqLgrDLz6ZIQDdWUI state_group=12 create_new_client_event m.room.message event=$PAbkJRMxb0bX4A6av463faiAhxkE3FEObM1xB4D0UG4 state_group=13 create_new_client_event org.matrix.msc2716.batch event=$Oy_S7AWN7rJQe_MYwGPEy6RtbYklrI-tAhmfiLrCaKI state_group=14 ``` **After** (all events in batch sharing `state_group=10`) (the base insertion event has `state_group=8` which matches the `prev_event` we're inserting next to): ``` # Tests from https://github.com/matrix-org/complement/pull/206 $ COMPLEMENT_ALWAYS_PRINT_SERVER_LOGS=1 COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh TestBackfillingHistory/parallel/should_resolve_member_state_events_for_historical_events create_new_client_event m.room.member event=$PWomJ8PwENYEYuVNoG30gqtybuQQSZ55eldBUSs0i0U state_group=None create_new_client_event org.matrix.msc2716.insertion event=$e_mCU7Eah9ABF6nQU7lu4E1RxIWccNF05AKaTT5m3lw state_group=9 create_new_client_event org.matrix.msc2716.insertion event=$ui7A3_GdXIcJq0C8GpyrF8X7B3DTjMd_WGCjogax7xU state_group=10 create_new_client_event m.room.message event=$EnTIM5rEGVezQJiYl62uFBl6kJ7B-sMxWqe2D_4FX1I state_group=10 create_new_client_event m.room.message event=$LGx5jGONnBPuNhAuZqHeEoXChd9ryVkuTZatGisOPjk state_group=10 create_new_client_event m.room.message event=$wW0zwoN50lbLu1KoKbybVMxLbKUj7GV_olozIc5i3M0 state_group=10 create_new_client_event org.matrix.msc2716.batch event=$5ZB6dtzqFBCEuMRgpkU201Qhx3WtXZGTz_YgldL6JrQ state_group=10 ``` --- changelog.d/10975.feature | 1 + synapse/handlers/message.py | 57 +++++++++++-------- synapse/handlers/room_batch.py | 40 +++++++++---- synapse/rest/client/room_batch.py | 15 ++--- synapse/storage/databases/main/events.py | 10 ++-- synapse/storage/databases/main/room_batch.py | 13 +++++ synapse/storage/schema/__init__.py | 6 +- .../65/01msc2716_insertion_event_edges.sql | 19 +++++++ 8 files changed, 114 insertions(+), 47 deletions(-) create mode 100644 changelog.d/10975.feature create mode 100644 synapse/storage/schema/main/delta/65/01msc2716_insertion_event_edges.sql diff --git a/changelog.d/10975.feature b/changelog.d/10975.feature new file mode 100644 index 000000000..167426e1f --- /dev/null +++ b/changelog.d/10975.feature @@ -0,0 +1 @@ +Resolve and share `state_groups` for all [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) historical events in batch. diff --git a/synapse/handlers/message.py b/synapse/handlers/message.py index 4de9f4b82..2e024b551 100644 --- a/synapse/handlers/message.py +++ b/synapse/handlers/message.py @@ -607,29 +607,6 @@ class EventCreationHandler: builder.internal_metadata.historical = historical -

This means that it's possible for us to accept events which don't pass auth at their declared auth_events (or where the auth events themselves were rejected), leading to problems down the line like #10083. This change means we will: * ignore any events where we cannot find the auth events * reject any events whose auth events were rejected * reject any events which do not pass auth at their declared auth_events. Together with a whole raft of previous work, this is a partial fix to #9595. Fixes #6643.

This can be used to conveniently also validate the config is valid before trying to start Synapse. The "read" command broke in https://github.com/matrix-org/synapse/pull/10916 as it now requires passing in "server.server_name" for example. Also made the read command optional so one can just call this with just the confirm file reference and get a "Config parses OK" if things are ok.

As with other changes before this one (eg #10771), we need to make sure that we auth the auth events in the right order, and actually check that their predecessors haven't been rejected. To do this I've reused the existing code we use when persisting outliers elsewhere. I've removed the code for attempting to fetch missing auth_events - the events should have been present in the send_join response, so the likely reason they are missing is that we couldn't verify them, so requesting them again is unlikely to help. Instead, we simply drop any state which relies on those auth events, as we do at a backwards-extremity. See also matrix-org/complement#216 for a test for this. --- changelog.d/11012.bugfix | 1 + synapse/handlers/federation_event.py | 144 +++++++++++---------------- 2 files changed, 60 insertions(+), 85 deletions(-) create mode 100644 changelog.d/11012.bugfix diff --git a/changelog.d/11012.bugfix b/changelog.d/11012.bugfix new file mode 100644 index 000000000..13b8e5983 --- /dev/null +++ b/changelog.d/11012.bugfix @@ -0,0 +1 @@ +Fix a long-standing bug which meant that events received over federation were sometimes incorrectly accepted into the room state. diff --git a/synapse/handlers/federation_event.py b/synapse/handlers/federation_event.py index 3431a80ab..9584d5bd4 100644 --- a/synapse/handlers/federation_event.py +++ b/synapse/handlers/federation_event.py @@ -361,6 +361,7 @@ class FederationEventHandler: # need to. await self._event_creation_handler.cache_joined_hosts_for_event(event, context) + await self._check_for_soft_fail(event, None, origin=origin) await self._run_push_actions_and_persist_event(event, context) return event, context @@ -402,29 +403,28 @@ class FederationEventHandler: """Persists the events returned by a send_join Checks the auth chain is valid (and passes auth checks) for the - state and event.
