Also rework elixir dependency handling, so we no longer rely on mix to
fetch the rabbitmq_cli deps
Also:
- Specify ra version with a commit rather than a branch
- Fixup compilation options for erlang 23
- Add missing ra reference in MODULE.bazel
- Add missing flag in oci.yaml
- Reduce bazel rbe jobs to try to save memory
- Use bazel built erlang for erlang git master tests
- Use the same cache for all the workflows but windows
- Avoid using `mix local.hex --force` in elixir rules
- Fetching seems blocked in CI, and this should reduce hex api usage in
all builds, which is always nice
- Remove xref and dialyze tags since rules_erlang 3 includes them in
the defaults
rabbitmq_cli uses some private rules_erlang apis that have changed in
the upcoming release
Additionally:
- Avoid including both standard and test versions of amqp_client in
integration test suites
- Eliminate most of the compilation order hints (explicit first_srcs)
in the bazel build
- Fix an include statement - in bazel, an app is not available to
itself as a library at compilation time
bazel-erlang has been renamed rules_erlang. v2 is a substantial
refactor that brings Windows support. While this alone isn't enough to
run all rabbitmq-server suites on windows, one can at least now start
the broker (bazel run broker) and run the tests that do not start a
background broker process
This way we can show how many messages were received via a certain
protocol (stream is the second real protocol besides the default amqp091
one), as well as by queue type, which is something that many asked for a
really long time.
The most important aspect is that we can also see them by protocol AND
queue_type, which becomes very important for Streams, which have
different rules from regular queues (e.g. for example, consuming
messages is non-destructive, and deep queue backlogs - think billions of
messages - are normal). Alerting and consumer scaling due to deep
backlogs will now work correctly, as we can distinguish between regular
queues & streams.
This has gone through a few cycles, with @mkuratczyk & @dcorbacho
covering most of the ground. @dcorbacho had most of this in
https://github.com/rabbitmq/rabbitmq-server/pull/3045, but the main
branch went through a few changes in the meantime. Rather than resolving
all the conflicts, and then making the necessary changes, we (@gerhard +
@kjnilsson) took all learnings and started re-applying a lot of the
existing code from #3045. We are confident in this approach and would
like to see it through. We continued working on this with @dumbbell, and
the most important changes are captured in
https://github.com/rabbitmq/seshat/pull/1.
We expose these global counters in rabbitmq_prometheus via a new
collector. We don't want to keep modifying the existing collector, which
grew really complex in parts, especially since we introduced
aggregation, but start with a new namespace, `rabbitmq_global_`, and
continue building on top of it. The idea is to build in parallel, and
slowly transition to the new metrics, because semantically the changes
are too big since streams, and we have been discussing protocol-specific
metrics with @kjnilsson, which makes me think that this approach is
least disruptive and... simple.
While at this, we removed redundant empty return value handling in the
channel. The function called no longer returns this.
Also removed all DONE / TODO & other comments - we'll handle them when
the time comes, no need to leave TODO reminders.
