Bazel build files are now maintained primarily with `bazel run
gazelle`. This will analyze and merge changes into the build files as
necessitated by certain code changes (e.g. the introduction of new
modules).
In some cases there hints to gazelle in the build files, such as `#
gazelle:erlang...` or `# keep` comments. xref checks on plugins that
depend on the cli are a good example.
- Use the same base .plt everywhere, so there is no need to list
standard apps everywhere
- Fix typespecs: some typos and the use of not-exported types
1. Allow to inspect an (web) MQTT connection.
2. Show MQTT client ID on connection page as part of client_properties.
3. Handle force_event_refresh (when management_plugin gets enabled
after (web) MQTT connections got created).
4. Reduce code duplication between protocol readers.
5. Display '?' instead of 'NaN' in UI for absent queue metrics.
6. Allow an (web) MQTT connection to be closed via management_plugin.
For 6. this commit takes the same approach as already done for the stream
plugin:
The stream plugin registers neither with {type, network} nor {type,
direct}.
We cannot use gen_server:call/3 anymore to close the connection
because the web MQTT connection cannot handle gen_server calls (only
casts).
Strictly speaking, this commit requires a feature flag to allow to force
closing stream connections from the management plugin during a rolling
update. However, given that this is rather an edge case, and there is a
workaround (connect to the node directly hosting the stream connection),
this commit will not introduce a new feature flag.
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
Some tools such as nvim + erlang_ls sometimes change the cwd if
they encounter a rebar.config. Here we move all rebar.config files
into the root of the project to avoid this and also have a single
point for formatting configuration.
The UI handles the case where the 2 fields are not present.
This can happen in a mixed-version cluster, where a node
of a previous version returns records without the fields.
The UI uses default values (active = true, activity status = up),
which is valid as the consumers of the node are "standalone"
consumers (not part of a group).

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
In test suite. Note a snapshot for 1.0-SNAPSHOT has been
pushed by mistake a while ago, so this one must be
excluded. It's unlikely it will be erased, as the snapshots
for the first stable version should be 1.0.0-SNAPSHOT.
This is an important metric to keep track of and be aware (maybe even
alert on) when consumers fall behind consuming stream messages. While
they should be able to catch up, if they fall behind too much and the
stream gets truncated, they may miss on messages.
This is something that we want to expose via Prometheus metrics as well,
but we've started closer to the core, CLI & Management.
This should be merged as soon as it passes CI, we shouldn't wait on the
Prometheus changes - they can come later.

This allows including additional applications or third party
plugins when creating a release, running the broker locally,
or just building from the top-level Makefile.
To include Looking Glass in a release, for example:
$ make package-generic-unix ADDITIONAL_PLUGINS="looking_glass"
A Docker image can then be built using this release and will
contain Looking Glass:
$ make docker-image
Beware macOS users! Applications such as Looking Glass include
NIFs. NIFs must be compiled in the right environment. If you
are building a Docker image then make sure to build the NIF
on Linux! In the two steps above, this corresponds to Step 1.
To run the broker with Looking Glass available:
$ make run-broker ADDITIONAL_PLUGINS="looking_glass"
This commit also moves Looking Glass dependency information
into rabbitmq-components.mk so it is available at all times.
The configuration remains the same for the end-user. The only exception
is the log root directory: it is now set through the `log_root`
application env. variable in `rabbit`. People using the Cuttlefish-based
configuration file are not affected by this exception.
The main change is how the logging facility is configured. It now
happens in `rabbit_prelaunch_logging`. The `rabbit_lager` module is
removed.
The supported outputs remain the same: the console, text files, the
`amq.rabbitmq.log` exchange and syslog.
The message text format slightly changed: the timestamp is more precise
(now to the microsecond) and the level can be abbreviated to always be
4-character long to align all messages and improve readability. Here is
an example:
2021-03-03 10:22:30.377392+01:00 [dbug] <0.229.0> == Prelaunch DONE ==
2021-03-03 10:22:30.377860+01:00 [info] <0.229.0>
2021-03-03 10:22:30.377860+01:00 [info] <0.229.0> Starting RabbitMQ 3.8.10+115.g071f3fb on Erlang 23.2.5
2021-03-03 10:22:30.377860+01:00 [info] <0.229.0> Licensed under the MPL 2.0. Website: https://rabbitmq.com
The example above also shows that multiline messages are supported and
each line is prepended with the same prefix (the timestamp, the level
and the Erlang process PID).
JSON is also supported as a message format and now for any outputs.
Indeed, it is possible to use it with e.g. syslog or the exchange. Here
is an example of a JSON-formatted message sent to syslog:
Mar 3 11:23:06 localhost rabbitmq-server[27908] <0.229.0> - {"time":"2021-03-03T11:23:06.998466+01:00","level":"notice","msg":"Logging: configured log handlers are now ACTIVE","meta":{"domain":"rabbitmq.prelaunch","file":"src/rabbit_prelaunch_logging.erl","gl":"<0.228.0>","line":311,"mfa":["rabbit_prelaunch_logging","configure_logger",1],"pid":"<0.229.0>"}}
For quick testing, the values accepted by the `$RABBITMQ_LOGS`
environment variables were extended:
* `-` still means stdout
* `-stderr` means stderr
* `syslog:` means syslog on localhost
* `exchange:` means logging to `amq.rabbitmq.log`
`$RABBITMQ_LOG` was also extended. It now accepts a `+json` modifier (in
addition to the existing `+color` one). With that modifier, messages are
formatted as JSON intead of plain text.
The `rabbitmqctl rotate_logs` command is deprecated. The reason is
Logger does not expose a function to force log rotation. However, it
will detect when a file was rotated by an external tool.
From a developer point of view, the old `rabbit_log*` API remains
supported, though it is now deprecated. It is implemented as regular
modules: there is no `parse_transform` involved anymore.
In the code, it is recommended to use the new Logger macros. For
instance, `?LOG_INFO(Format, Args)`. If possible, messages should be
augmented with some metadata. For instance (note the map after the
message):
?LOG_NOTICE("Logging: switching to configured handler(s); following "
"messages may not be visible in this log output",
#{domain => ?RMQLOG_DOMAIN_PRELAUNCH}),
Domains in Erlang Logger parlance are the way to categorize messages.
Some predefined domains, matching previous categories, are currently
defined in `rabbit_common/include/logging.hrl` or headers in the
relevant plugins for plugin-specific categories.
At this point, very few messages have been converted from the old
`rabbit_log*` API to the new macros. It can be done gradually when
working on a particular module or logging.
The Erlang builtin console/file handler, `logger_std_h`, has been forked
because it lacks date-based file rotation. The configuration of
date-based rotation is identical to Lager. Once the dust has settled for
this feature, the goal is to submit it upstream for inclusion in Erlang.
The forked module is calld `rabbit_logger_std_h` and is based
`logger_std_h` in Erlang 23.0.
Depending on whether the "owner" of the consumer is a channel (for AMQP
consumers) or a connection (for stream consumers) and whether the stream
management plugin is enabled or not. The link will lead to the channel
page, the connection page, or the stream connection page.
