This function returns the data directory where all subsystems should
store their files.
Historically, this was the Mnesia directory. But semantically, this
should be the reverse: RabbitMQ owns the data directory and Mnesia is
configured to put its files there too.
`rabbit_mnesia:dir/0` now calls `rabbit:data_dir/0`.
Other subsystems will be modified in a follow-up commit to call
`rabbit:data_dir/0` instead of `rabbit_mnesia:dir/0`.
The location and name of this directory remains the same for
compatibility reasons. Therefore, it sill contains "mnesia" in its name.
However, semantically, we want this directory to be unrelated to Mnesia.
In the end, many subsystems write files and directories there, including
Mnesia, all Ra systems and in the future, Khepri.
This value is used internally by `rabbit_env` and usually not read by
RabbitMQ otherwise.
This patch prepares the rename of `mnesia_dir` to `data_dir`, in order
to not semantically rely on Mnesia configuration or use to locate data,
whether it is stored in Mnesia or not.
Seems like we are not using it anywhere in our code base.
It's unlikely that it's used somewhere else and even if it is,
the API is backwards compatible - we just pass 0, as if the priority_queue
was empty.
That was done in PR #3865.
The changes introduced in #3865 can cause message arrival ordering guarantees
between two logical erlang process (sending messages via delegate) to
be violated as a message sent to a single destination can overtake a prior
message sent as part of a fan-out. This is due to the fact that the fan-out
take a different route via the delegate process than the direct delivery that
bypasses it.
This commit only reverses it for the `invoke_no_result/2|3` API and leaves the
optimisation in for the synchronous `invoke/` API. This means that the message
send ordering you expect between erlang processes still can be violated when
mixing invoke and invoke_no_result invocations. As far as I can see there are
no places where the code relies on this and there are uses of invoke (mgmt db)
that very well could benefit from avoiding the additional copying.
This category should be unused with the decommissioning of the old
upgrade subsystem (in favor of the feature flags subsystem). It means:
1. The upgrade log file will not be created by default anymore.
2. The `$RABBITMQ_UPGRADE_LOG` environment variable is now unsupported.
The configuration variables remain to avoid breaking an existing and
working configuration.

Ensure externally read strings are saved as utf-8 encoded binaries. This
is necessary since `cmd.exe` on Windows uses ISO-8859-1 encoding and
directories can have latin1 characters, like `RabbitMQ Sérvér`.
The `é` is represented by decimal `233` in the ISO-8859-1 encoding. The
unicode code point is the same decimal value, `233`, so you will see
this in the charlist data. However, when encoded using utf-8, this
becomes the two-byte sequence `C3 A9` (hexidecimal).
When reading strings from env variables and configuration, they will be
unicode charlists, with each list item representing a unicode code
point. All of Erlang string functions can handle strings in this form.
Once these strings are written to ETS or Mnesia, they will be converted
to utf-8 encoded binaries. Prior to these changes just
`list_to_binary/1` was used.

Stop sending connection_stats from protocol readers to rabbit_event.
Stop sending queue_stats from queues to rabbit_event.
Sending these stats every 5 seconds to the event manager process is
superfluous because noone handles these events.
They seem to be a relict from before rabbit_core_metrics ETS tables got
introduced in 2016.
Delete test head_message_timestamp_statistics because it tests that
head_message_timestamp is set correctly in queue_stats events

The functionality of head_message_timestamp itself is still tested in
deps/rabbit/test/priority_queue_SUITE.erl and
deps/rabbit/test/temp/head_message_timestamp_tests.py
in e.g. the `advanced.config` file, or manually in runtime.
This also adds tracing through use of `rabbit_event`, controllable by
use of compile time flag, e.g. TRACE_SUP2.
A couple users reported `badmatch` crashes due to scenarios where
`inet:peername/1` does not return the expected value, most likely due to
the port closing between the time they are listed and when
`inet:peername/1` is called.

In the process we have discovered an issue:

This avoids printing the full stacktrace when the error comes from the

In practice, when testing with bazel with macos, sysctl is blocked by
the sandbox, so logging the stacktrace is rather noisy for tests
This gen_statem-based process is responsible for handling concurrency
when feature flags are enabled and synchronized when a cluster is
expanded.
This clarifies and stabilizes the behavior of the feature flag subsystem
w.r.t. situations where e.g. a feature flag migration function takes
time to update data and a new node joins a cluster and synchronizes its
feature flag states with the cluster. There was a chance that the
feature flag was marked as enabled on the joining node, even though the
migration function didn't take care of that node.
With this new feature flags controller, enabling or synchronizing
feature flags blocks and delays any concurrent operations which try to
modify feature flags states too.
This change also clarifies where and when the migration function is
called: it is called at least once on each node who knows the feature
flag and when the state goes from "disabled" to "enabled" on that node.
Note that even if the feature flag is being enabled on a subset of the
nodes (because other nodes already have it enabled), it is marked as
"state_changing" everywhere during the migration. This is to prevent
that a node where it is enabled assumes it is enabled on all nodes who
know the feature flag.
There is a new feature as well: just after a feature flag is enabled,
the migration function is called a second time for any post-enable
actions. The feature flag is marked as enabled between these "enable"
and "post-enable" steps. The success or failure of this "post-enable"
run does not affect the state of the feature flag (i.e. it is ignored).
A new migration function API is introduced to allow more advanced
things. The new API is:
my_migration_function(
#ffcommand{name = ...,
props = ...,
command = enable | post_enable,
extra = #{...}})
The record is defined in `include/feature_flags.hrl`. Here is the
meaning of each field:
* `name` and `props` are the equivalent of the `FeatureName` and
`FeatureProps` arguments of the previous migration function API.
* `command` is basically the same as the previous `Arg` arguments.
* `extra` is map containing context-specific information. For instance, it
contains the list of nodes where the feature flag state changes.
This whole new behavior is behind a new feature flag called
`feature_flags_v2`. If a feature flag uses the new migration function
API, `feature_flags_v2` will be automatically enabled.
If many feature flags are enabled at once (like when a fresh RabbitMQ
node is started for the first time), `feature_flags_v2` will be enabled
first if it is in the list.

In this commit, we disallow expiry fields higher than 100 years.
This causes the channel to be closed which is better than crashing the
queue process.
This new validation applies to message TTLs and queue expiry.
From the docs of erlang:start_timer:
"The absolute point in time, the timer is set to expire on, must be in the interval
[erlang:convert_time_unit(erlang:system_info(start_time), native, millisecond),
erlang:convert_time_unit(erlang:system_info(end_time), native, millisecond)].
If a relative time is specified, the Time value is not allowed to be negative.
end_time:
The last Erlang monotonic time in native time unit that can be represented
internally in the current Erlang runtime system instance.
The time between the start time and the end time is at least a quarter of a millennium."
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
In particular:
- io_file_handle_open_attempt
- queue_index_journal_write
Neither have proven to be very useful in recent years
and with the move to FHC-less and journal-less v2 index
they will slowly become irrelevant. This should be a
good compromise until we can switch to v2 permanently
or rework the stats module to use counters.
During most of the time the file_handle_cache_stats ets table is
used for writing only.
By enabeling `write_concurrency` on the table we allow different values
to be written concurrently without taking a global lock.
There the only codepath reading from the ets table is run on the
`collect_statistics_interval` interval and reads the whole table.
So we can assume we are not blocking any large amount of concurrent reads.
as an opt-in feature. The goal is to avoid re-importing the definition
from the definition file/directory/source if we know the content
has not changed. Since this feature won't be appropriate for
every environment (sometimes unconditional reimporting is expected),
the feature is opt-in.
This is still a WIP.
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

background broker process
This is to address another memory leak on win32 reported here:
https://groups.google.com/g/rabbitmq-users/c/UE-wxXerJl8
"RabbitMQ constant memory increase (binary_alloc) in idle state"
The root cause is the Prometheus plugin making repeated calls to `rabbit_misc:otp_version/0` which then calls `file:read_file/1` and leaks memory on win32.

Turn `badmatch` into actual error
This is copied from https://github.com/rabbitmq/rabbitmq-common/pull/349
If a message is sent to only one queue(in most application scenarios), passing through the 'delegate' is meaningless. Otherwise, it increases the delay of the message and the possibility of 'delegate' congestion.
Here are some test data：
node1: Pentium(R) Dual-Core CPU E5300 @ 2.60GHz
node2: Pentium(R) Dual-Core CPU E5300 @ 2.60GHz
Join node1 and node2 to a cluster. Create 100 queues on node2, and start 100 consumers to receive messages from these queues.
Start 100 publishers on node1 to send messages to the queues of node2. Each publisher will send 10k messages at the rate of 100/s(10k/s theoretically in total), and all the messages for all publishers is 1 million.
Before optimisation:
{1,[{msg_time,812312(=<1ms),177922(=<5ms),9507(=<50ms),221(=<500ms),38(=<1000ms),0,0,0,0,1061,1069,0,0}]}
After optimisation:
{1,[{msg_time,902854(=< 1ms),93993(=<5ms),3038(=<50ms),96(=<500ms),19(=<1000ms),0,0,0,0,1049,1060,0,0}]}
Additional information:
Time counted here is the stay time of a message in the cluster, that is, Time(leaving from node2 at) - Time(reaching node1 at).
"812312(=<1ms)" is the number of messages with time consumption less than or equal to 1ms.
Overall, the optimisation is effective.
It was automatically happening for e.g. `make start-cluster`.
But some plugins were not covered by default generated config, and
running rabbit from 2 different worktrees was a bit complicated.
A value that is too low will prevent the index from shutting
down in time when there are many queues. This leads to the
process being killed and on the next RabbitMQ restart a
(potentially very long) dirty recovery is needed.
The value of 10 minutes was chosen to mirror the shutdown
timeout of the message store. Since both queues and message
store need to have shut down gracefully in order to have
a clean restart it makes sense to use the same value.

A user could already enable single-line logging (the `single_line`
option of `logger_formatter` or RabbitMQ internal formatters) from the
configuration file. For example:
log.console.formatter.single_line = on
With this patch, the option can be enabled from the `$RABBITMQ_LOG`
environment variable as well:
make run-broker RABBITMQ_LOG=+single_line
Those environment variables are unset by default. The default values are
set in the `rabbit` application environment and can be configured in the
configuration file. However, the environment variables will take
precedence over them respectively if they are set.
They were trying to run `hostname` and `which`, which produced a bunch
of error messages in a hermetic build environment.
And performance of those `shell` calls is not very important, as they
are caled just a few times during script runtime anyway (there is a
hack to make these lazy, but evaluating only once - but it's hardly
worth it).
Unlike pg2, pg in Erlang 24 is eventually consistent. So this
reintroduces some of the same kind of locking mirrored_supervisor
used to rely on implicitly via pg2.

This is still not perfect because we limit the maximum

The parser didn't handle literals of the form:
'single-quoted'unquoted'single-quoted-again'"or-even-double-quoted"

follow it. The testsuite is extended with the issue reporter's case.
While here, improve escaped characters handling. They used to be not
parsed specifically at all.

In kind version 0.10.0, when creating a 5-node RabbitMQ cluster

Eventually, after some pods restarted up to 2 times, all pods were running and ready.
In kind, we observed that during the first couple of seconds, nslookup was failing as well for that domain
with nxdomain.
It took up to 30 seconds until nslookup succeeded.
With this commit, pods don't need to be restarted when creating a fresh
RabbitMQ cluster.
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.
Lager strips trailing newline characters but OTP logger with the default
formatter adds a newline at the end. To avoid unintentional multi-line log
messages we have to revisit most messages logged.
Some log entries are intentionally multiline, others
are printed to stdout directly: newlines are required there
for sensible formatting.
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.
Subsequent nodes fail to start since ports are already in use. This
makes it possible to start multiple nodes locally with all plugins
enabled.

as node names grow.
Prior to this change, direct reply-to consumer channels
were encoded using term_to_binary/1, which means the result
would grow together with node name (since node name
is one of the components of an Erlang pid type).
This means that with long enough hostnames, reply-to
identifiers could overflow the 255 character limit of
message property field type, longstr.
With this change, the encoded value uses a hash of the node name
and then locates the actual node name from a map of
hashes to current cluster members.
In addition, instead of generating non-predictable "secure"
GUIDs the feature now generates "regular" predictable GUIDs
which compensates some of the additional PID pre- and post-processing
outlined above.
Now that dependencies are packaged as directories and not .ez
files, the fact that both LG and LZ4 are NIFs is no longer
an issue. And having it as regular dependencies simplifies
REPL-driven profiling.
Per discussion with @dumbbell.
The `set` command in the implementation of `/bin/sh` included in the
official RabbitMQ Docker image returns multi-line variable values
differently than the tested Bourne shell implementation (GNU Bash, dash
and FreeBSD sh).
I don't know what implementation is used by that Docker image, but here
is the output of `set`, for a variable set to "\n'test'":
TEST_VAR='
'"'"'test'"'"
The problem was reported in the following discussion:
https://github.com/rabbitmq/rabbitmq-server/discussions/2458
While here, add a small testcase to check a couple outputs.
... instead of 23.0.
Erlang 23.1 is the version the Concourse pipelines use. We expect the
Concourse pipelines and the GitHub Actions workflow to be on the same
page.
GC collection can then be done by deleting all entries on the ETS table
and total counters per protocol can be kept without individually scanning
all entries
