Hello,
I'm writing on behalf of the Citadel product developed by ERCOM.
This PR bumps `pyo3` from 0.26.0 to 0.27.2 and `pythonize` from 0.26.0
to 0.27.0.
For the code migration I followed the guide found here:
[link](https://pyo3.rs/v0.27.0/migration.html).
We're already using `job=~"$job"` in the majority of the other panels.
This is just aligning the stragglers.
### Background
For a variable in Grafana, when the "All" value is selected, it
translates the variable into a wildcard regex. By default, this is just
a giant list of all of the possible values or'd together. It's possible
to define a "custom all value" like we've done for `index` as `.*` and
feels like we should also do this in a follow-up PR.
Input:
```
job="$job"
```
Before (using **exact** match) -> resulted in matching nothing:
```
job="(appservice|background_worker|client_reader|device_lists|event_creator|event_persister|federation_inbound|federation_reader|federation_sender|media_repository|pusher|stream_writers|synapse|synchrotron|user_dir)""
```
After (using **regex** match) -> matches all jobs as expected:
```
job=~"(appservice|background_worker|client_reader|device_lists|event_creator|event_persister|federation_inbound|federation_reader|federation_sender|media_repository|pusher|stream_writers|synapse|synchrotron|user_dir)""
```
On restart we retry joining partially stated rooms, but if you have a
bunch in the database this can cause big performance issues if we start
them all at once. So we stagger them.
When we change the `required_state` config for a room in sliding sync,
we insert a new entry into the `sliding_sync_connection_required_state`
table. As the sliding sync connection advances we can accrue a lot of
stale entries, so let's clear those out.
This is a sort of follow on from #19211

Follow-up to https://github.com/element-hq/synapse/pull/19383
The
[`ProxiedReactor`](079c52e16b/synapse/app/complement_fork_starter.py (L38-L71))
is a special custom reactor used in the
`synapse/app/complement_fork_starter.py`. It's used by default when
using `WORKERS=1 ./scripts-dev/complement.sh` (see
`SYNAPSE_USE_EXPERIMENTAL_FORKING_LAUNCHER`). The point of the forking
launcher is to improve start-up times and the point of the
[`ProxiedReactor`](079c52e16b/synapse/app/complement_fork_starter.py (L38-L71))
is explained in the [docstring](079c52e16b/synapse/app/complement_fork_starter.py (L38-L56))
(introduced in https://github.com/matrix-org/synapse/pull/13127)
### Reproduction instructions
1. Using the Complement scripts **with workers**: `WORKERS=1
COMPLEMENT_DIR=../complement ./scripts-dev/complement.sh ./tests/csapi`
1. `docker logs complement_csapi_dirty_hs1 2>&1 | grep -i "reactor"`
1. With these changes, notice `Twisted reactor: ProxiedReactor` but no
warning about `Skipping configuring ReactorLastSeenMetric: unexpected
reactor type: <__main__.ProxiedReactor object at 0x7fc0adaaea50>`
1. Cleanup:
- `docker stop $(docker ps --all --filter "label=complement_context"
--quiet)`
- `docker rm $(docker ps --all --filter "label=complement_context"
--quiet)`
To test that we're actually seeing reactor metrics, I've been using this
with the load-test runs in
https://github.com/element-hq/synapse-rust-apps/pull/397
Fixes#19375
`prometheus_client` 0.24 makes `Collector` a generic type.
Previously, `InFlightGauge` inherited from both `Generic[MetricsEntry]`
and `Collector`, resulting in the error `TypeError: cannot create a
consistent MRO` when using `prometheus_client` >= 0.24. This behaviour
of disallowing multiple `Generic` inheritance is more strictly enforced
starting with python 3.14, but can still lead to issues with earlier
versions of python.
This PR separates runtime and typing inheritance for `InFlightGauge`:
- Runtime: `InFlightGauge` inherits only from `Collector`
- Typing: `InFlightGauge` is generic
This preserves static typing, avoids MRO conflicts, and supports both
`prometheus_client` <0.24 and >=0.24.
I have tested these changes out locally with `prometheus_client` 0.23.1
& 0.24 on python 3.14 while sending a bunch of messages over federation
and watching a grafana dashboard configured to show
`synapse_util_metrics_block_in_flight_total` &
`synapse_util_metrics_block_in_flight_real_time_sum` (the only metric
setup to use `InFlightGauge`) and things are working in each case.

before submitting your pull request -->
* [X] Pull request is based on the develop branch
* [X] Pull request includes a [changelog
file](https://element-hq.github.io/synapse/latest/development/contributing_guide.html#changelog).
The entry should:
- Be a short description of your change which makes sense to users.
"Fixed a bug that prevented receiving messages from other servers."
instead of "Moved X method from `EventStore` to `EventWorkerStore`.".
- Use markdown where necessary, mostly for `code blocks`.
- End with either a period (.) or an exclamation mark (!).
- Start with a capital letter.
- Feel free to credit yourself, by adding a sentence "Contributed by
@github_username." or "Contributed by [Your Name]." to the end of the
entry.
* [X] [Code
style](https://element-hq.github.io/synapse/latest/code_style.html) is
correct (run the
[linters](https://element-hq.github.io/synapse/latest/development/contributing_guide.html#run-the-linters))
These are automatic changes from importing/exporting from Grafana
12.3.1.
In order to verify that I'm not sneaking in any changes, you can follow
these steps to get the same output.
Reproduction instructions:
1. Start [Grafana](https://hub.docker.com/r/grafana/grafana)
```
docker run -d --name=grafana --add-host
host.docker.internal:host-gateway -p 3000:3000 grafana/grafana
```
1. Visit the Grafana dashboard, http://localhost:3000/ (Credentials:
`admin`/`admin`)
1. Import the Synapse dashboard: `contrib/grafana/synapse.json`
1. Export the Synapse dashboard. On the dashboard page -> **Export** ->
**Export as code** -> Using the **Classic** model -> Check **Export for
sharing externally** -> Copy
1. Paste into `contrib/grafana/synapse.json`
1. `git status`/`git diff` to check if there is any diff
Sanity checked the dashboard itself by importing the dashboard on
https://grafana.matrix.org/ (Grafana 10.4.1 according to
https://grafana.matrix.org/api/health). The process-level metrics won't
work because https://github.com/element-hq/synapse/pull/19337 just
merged and isn't on `matrix.org` yet. Also just generally, this
dashboard works for me locally with the
[load-tests](https://github.com/element-hq/synapse-rust-apps/pull/397)
I've been doing.
### Motivation
There are few fixes I want to make to the Grafana dashboard and it sucks
having to manually translate everything back over because we have
different formatting.
Hopefully after this bulk change, future exports will have exactly what
we want to change.
Spawning from not seeing any reactor metrics in the Grafana dashboard in
some load tests, noticing `python_twisted_reactor_tick_time_bucket` is
`0` in Prometheus, following it back to Synapse and seeing that we don't
warn about skipping reactor metrics in all cases (when using an unknown
reactor type).
A follow-up to this would be to actually figure out how to instrument
the `ProxiedReactor` or why `ProxiedReactor` is being chosen in the
first place and see if we can get it to use a more normal type
🤔
### Reproduction instructions
1. Using the Complement scripts **with workers**: `WORKERS=1
./scripts-dev/complement.sh ./tests/csapi`
1. `docker logs complement_csapi_dirty_hs1 2>&1 | grep -i "reactor"`
1. With these changes, notice `Skipping configuring
ReactorLastSeenMetric: unexpected reactor type: <__main__.ProxiedReactor
object at 0x7fc0adaaea50>` and `Twisted reactor: ProxiedReactor`
1. Cleanup:
- `docker stop $(docker ps --all --filter "label=complement_context"
--quiet)`
- `docker rm $(docker ps --all --filter "label=complement_context"
--quiet)`
I'm unable to reproduce with the normal Synapse images or
`complement-synapse` without workers. They all use `Twisted reactor:
EPollReactor`
<details>
<summary>Checking <code>docker/Dockerfile-workers</code></summary>
1. Build the Docker image for Synapse: `docker build -t
matrixdotorg/synapse -f docker/Dockerfile . && docker build -t
matrixdotorg/synapse-workers -f docker/Dockerfile-workers .`
([docs](7a24fafbc3/docker/README-testing.md (building-and-running-the-images-manually)))
1. Start Synapse:
```
docker run -d --name synapse \
--mount type=volume,src=synapse-data,dst=/data \
-e SYNAPSE_SERVER_NAME=my.docker.synapse.server \
-e SYNAPSE_REPORT_STATS=no \
-e SYNAPSE_ENABLE_METRICS=1 \
-p 8008:8008 \
-p 9469:9469 \
matrixdotorg/synapse-workers:latest
```
1. `docker logs synapse 2>&1 | grep -i "reactor"`
1. Says `Twisted reactor: EPollReactor`
</details>
Store the JSON content of scheduled delayed events as text instead of a
byte array. This brings it in line with the `event_json` table's `json`
column, and fixes the inability to schedule a delayed event with
non-ASCII characters in its content.
Fixes#19242
- Update `synapse_xxx` (server-level) metrics to use
`server_name="$server_name",` instead of `instance="$instance"`
- Add `synapse_server_name_info` metric to map Synapse `server_name`s to
the `instance`s they're hosted on.
- For process level metrics, update to use `xxx * on (instance, job,
index) group_left(server_name)
synapse_server_name_info{server_name="$server_name"}`
All of the changes here are backwards compatible with whatever people
were doing before with their Prometheus/Grafana dashboards.
Previously, the recommendation was to use the `instance` label to group
everything under the same server (803e4b4d88/docs/metrics-howto.md (L93-L147))
But the `instance` label actually has a special meaning and we're
actually abusing it by using it that way:
> `instance`: The `<host>:<port>` part of the target's URL that was
scraped.
>
> *--
https://prometheus.io/docs/concepts/jobs_instances/#automatically-generated-labels-and-time-series*
Since https://github.com/element-hq/synapse/issues/18592 (Synapse
`v1.139.0`), we now have the `server_name` label to use instead.
---
Additionally, the assumption that a single process is serving a single
server is no longer true with [Synapse Pro for small
hosts](https://docs.element.io/latest/element-server-suite-pro/synapse-pro-for-small-hosts/overview/).
Part of https://github.com/element-hq/synapse-small-hosts/issues/106
### Motivating use case
Although this change also benefits [Synapse Pro for small
hosts](https://docs.element.io/latest/element-server-suite-pro/synapse-pro-for-small-hosts/overview/)
(https://github.com/element-hq/synapse-small-hosts/issues/106), this is
actually spawning from adding Prometheus metrics to our workerized
Docker image (https://github.com/element-hq/synapse/pull/19324,
https://github.com/element-hq/synapse/pull/19336) with a more correct
label setup (without `instance`) and wanting the dashboard to be better.
### Testing strategy
1. Make sure your firewall allows the Docker containers to communicate
to the host (`host.docker.internal`) so they can access exposed ports of
other Docker containers. We want to allow Synapse to access the
Prometheus container and Grafana to access to the Prometheus container.
- `sudo ufw allow in on docker0 comment "Allow traffic from the default
Docker network to the host machine (host.docker.internal)"`
- `sudo ufw allow in on br-+ comment "(from Matrix Complement testing)
Allow traffic from custom Docker networks to the host machine
(host.docker.internal)"`
- [Complement firewall
docs](ee6acd9154/README.md (potential-conflict-with-firewall-software))
1. Build the Docker image for Synapse: `docker build -t
matrixdotorg/synapse -f docker/Dockerfile .`
([docs](7a24fafbc3/docker/README-testing.md (building-and-running-the-images-manually)))
1. Generate config for Synapse:
```
docker run -it --rm \
--mount type=volume,src=synapse-data,dst=/data \
-e SYNAPSE_SERVER_NAME=my.docker.synapse.server \
-e SYNAPSE_REPORT_STATS=yes \
-e SYNAPSE_ENABLE_METRICS=1 \
matrixdotorg/synapse:latest generate
```
1. Start Synapse:
```
docker run -d --name synapse \
--mount type=volume,src=synapse-data,dst=/data \
-p 8008:8008 \
-p 19090:19090 \
matrixdotorg/synapse:latest
```
1. You should be able to see metrics from Synapse at
http://localhost:19090/_synapse/metrics
1. Create a Prometheus config (`prometheus.yml`)
```yaml
global:
scrape_interval: 15s
scrape_timeout: 15s
evaluation_interval: 15s
scrape_configs:
- job_name: prometheus
scrape_interval: 15s
metrics_path: /_synapse/metrics
scheme: http
static_configs:
- targets:
# This should point to the Synapse metrics listener (we're using
`host.docker.internal` because this is from within the Prometheus
container)
- host.docker.internal:19090
```
1. Start Prometheus (update the volume bind mount to the config you just
saved somewhere):
```
docker run \
--detach \
--name=prometheus \
--add-host host.docker.internal:host-gateway \
-p 9090:9090 \
-v
~/Documents/code/random/prometheus-config/prometheus.yml:/etc/prometheus/prometheus.yml
\
prom/prometheus
```
1. Make sure you're seeing some data in Prometheus. On
http://localhost:9090/query, search for `synapse_build_info`
1. Start [Grafana](https://hub.docker.com/r/grafana/grafana)
```
docker run -d --name=grafana --add-host
host.docker.internal:host-gateway -p 3000:3000 grafana/grafana
```
1. Visit the Grafana dashboard, http://localhost:3000/ (Credentials:
`admin`/`admin`)
1. **Connections** -> **Data Sources** -> **Add data source** ->
**Prometheus**
- Prometheus server URL: `http://host.docker.internal:9090`
1. Import the Synapse dashboard: `contrib/grafana/synapse.json`
To test workers, you can use the testing strategy from
https://github.com/element-hq/synapse/pull/19336 (assumes both changes
from this PR and the other PR are combined)
Fixes#19347
This deprecates MSC2697 which has been closed since May 2024. As per
#19347 this seems to be a thing we can just rip out. The crypto team
have moved onto MSC3814 and are suggesting that developers who rely on
MSC2697 should use MSC3814 instead.
