Message Containers (#5077)
This PR implements an approach for a "protocol (data format) agnostic core" where the format of the message isn't converted at point of reception.
Currently all non AMQP 0.9.1 originating messages are converted into a AMQP 0.9.1 flavoured basic_message record before sent to a queue. If the messages are then consumed by the originating protocol they are converted back from AMQP 0.9.1. For some protocols such as MQTT 3.1 this isn't too expensive as MQTT is mostly a fairly easily mapped subset of AMQP 0.9.1 but for others such as AMQP 1.0 the conversions are awkward and in some cases lossy even if consuming from the originating protocol.
This PR instead wraps all incoming messages in their originating form into a generic, extensible message container type (mc). The container module exposes an API to get common message details such as size and various properties (ttl, priority etc) directly from the source data type. Each protocol needs to implement the mc behaviour such that when a message originating form one protocol is consumed by another protocol we convert it to the target protocol at that point.
The message container also contains annotations, dead letter records and other meta data we need to record during the lifetime of a message. The original protocol message is never modified unless it is consumed.
This includes conversion modules to and from amqp, amqpl (AMQP 0.9.1) and mqtt.
COMMIT HISTORY:
* Refactor away from using the delivery{} record
In many places including exchange types. This should make it
easier to move towards using a message container type instead of
basic_message.
Add mc module and move direct replies outside of exchange
Lots of changes incl classic queues
Implement stream support incl amqp conversions
simplify mc state record
move mc.erl
mc dlx stuff
recent history exchange
Make tracking work
But doesn't take a protocol agnostic approach as we just convert
everything into AMQP legacy and back. Might be good enough for now.
Tracing as a whole may want a bit of a re-vamp at some point.

Do not use "maybe" as type name as "maybe" is a keyword since OTP 25
which makes Erlang LS complain.
* Dedup death queue names
* Fix function clause crashes
Fix failing tests in the MQTT shared_SUITE:
A classic queue message ID can be undefined as set in
https://github.com/rabbitmq/rabbitmq-server/blob/fbe79ff47b4edbc0fd95457e623d6593161ad198/deps/rabbit/src/rabbit_classic_queue_index_v2.erl#L1048
Fix failing tests in the MQTT shared_SUITE-mixed:
When feature flag message_containers is disabled, the
message is not an #mc{} record, but a #basic_message{} record.
* Fix is_utf8_no_null crash
Prior to this commit, the function crashed if invalid UTF-8 was
provided, e.g.:
```
1> rabbit_misc:is_valid_shortstr(<<"😇"/utf16>>).
** exception error: no function clause matching rabbit_misc:is_utf8_no_null(<<216,61,222,7>>) (rabbit_misc.erl, line 1481)
```
* Implement mqtt mc behaviour
For now via amqp translation.
This is still work in progress, but the following SUITEs pass:
```
make -C deps/rabbitmq_mqtt ct-shared t=[mqtt,v5,cluster_size_1] FULL=1
make -C deps/rabbitmq_mqtt ct-v5 t=[mqtt,cluster_size_1] FULL=1
```
* Shorten mc file names
Module name length matters because for each persistent message the #mc{}
record is persisted to disk.
```
1> iolist_size(term_to_iovec({mc, rabbit_mc_amqp_legacy})).
30
2> iolist_size(term_to_iovec({mc, mc_amqpl})).
17
```
This commit renames the mc modules:
```
ag -l rabbit_mc_amqp_legacy | xargs sed -i 's/rabbit_mc_amqp_legacy/mc_amqpl/g'
ag -l rabbit_mc_amqp | xargs sed -i 's/rabbit_mc_amqp/mc_amqp/g'
ag -l rabbit_mqtt_mc | xargs sed -i 's/rabbit_mqtt_mc/mc_mqtt/g'
```
* mc: make deaths an annotation + fixes
* Fix mc_mqtt protocol_state callback
* Fix test will_delay_node_restart

* Fix rabbit:rabbit_message_interceptor_SUITE-mixed
set_annotation/3 should not result in duplicate keys
* Fix MQTT shared_SUITE-mixed
Up to 3.12 non-MQTT publishes were always QoS 1 regardless of delivery_mode.
https://github.com/rabbitmq/rabbitmq-server/blob/75a953ce286a10aca910c098805a4f545989af38/deps/rabbitmq_mqtt/src/rabbit_mqtt_processor.erl#L2075-L2076
From now on, non-MQTT publishes are QoS 1 if durable.
This makes more sense.
The MQTT plugin must send a #basic_message{} to an old node that does
not understand message containers.
* Field content of 'v1_0.data' can be binary
Fix
```
bazel test //deps/rabbitmq_mqtt:shared_SUITE-mixed \
--test_env FOCUS="-group [mqtt,v4,cluster_size_1] -case trace" \
-t- --test_sharding_strategy=disabled
```
* Remove route/2 and implement route/3 for all exchange types.
This removes the route/2 callback from rabbit_exchange_type and
makes route/3 mandatory instead. This is a breaking change and
will require all implementations of exchange types to update their
code, however this is necessary anyway for them to correctly handle
the mc type.

mc: property/2 and correlation_id/message_id return type tagged values.
To ensure we can support a variety of types better.
The type type tags are AMQP 1.0 flavoured.
fix death recovery
mc_mqtt: impl new api
Add callbacks to allow protocols to compact data before storage
And make readable if needing to query things repeatedly.
bazel fix
* more decoding
* tracking mixed versions compat
* mc: flip default of `durable` annotation to save some data.
Assuming most messages are durable and that in memory messages suffer less
from persistence overhead it makes sense for a non existent `durable`
annotation to mean durable=true.
* mc conversion tests and tidy up
* mc make x_header unstrict again
* amqpl: death record fixes
* bazel
* amqp -> amqpl conversion test
* Fix crash in mc_amqp:size/1
Body can be a single amqp-value section (instead of
being a list) as shown by test
```
make -C deps/rabbitmq_amqp1_0/ ct-system t=java
```
on branch native-amqp.
* Fix crash in lists:flatten/1
Data can be a single amqp-value section (instead of
being a list) as shown by test
```
make -C deps/rabbitmq_amqp1_0 ct-system t=dotnet:roundtrip_to_amqp_091
```
on branch native-amqp.
* Fix crash in rabbit_writer
Running test
```
make -C deps/rabbitmq_amqp1_0 ct-system t=dotnet:roundtrip_to_amqp_091
```
on branch native-amqp resulted in the following crash:
```
crasher:
initial call: rabbit_writer:enter_mainloop/2
pid: <0.711.0>
registered_name: []
exception error: bad argument
in function size/1
called as size([<<0>>,<<"Sw">>,[<<160,2>>,<<"hi">>]])
*** argument 1: not tuple or binary

```
because #content.payload_fragments_rev is currently supposed to
be a flat list of binaries instead of being an iolist.
This commit fixes this crash inefficiently by calling
iolist_to_binary/1. A better solution would be to allow AMQP legacy's #content.payload_fragments_rev
to be an iolist.
* Add accidentally deleted line back
* mc: optimise mc_amqp internal format
By removint the outer records for message and delivery annotations
as well as application properties and footers.
* mc: optimis mc_amqp map_add by using upsert
* mc: refactoring and bug fixes
* mc_SUITE routingheader assertions
* mc remove serialize/1 callback as only used by amqp
* mc_amqp: avoid returning a nested list from protocol_state
* test and bug fix
* move infer_type to mc_util
* mc fixes and additiona assertions
* Support headers exchange routing for MQTT messages
When a headers exchange is bound to the MQTT topic exchange, routing
will be performend based on both MQTT topic (by the topic exchange) and
MQTT User Property (by the headers exchange).
This combines the best worlds of both MQTT 5.0 and AMQP 0.9.1 and
enables powerful routing topologies.
When the User Property contains the same name multiple times, only the
last name (and value) will be considered by the headers exchange.
* Fix crash when sending from stream to amqpl
When publishing a message via the stream protocol and consuming it via
AMQP 0.9.1, the following crash occurred prior to this commit:
```
crasher:
initial call: rabbit_channel:init/1
pid: <0.818.0>
registered_name: []
exception exit: {{badmatch,undefined},
[{rabbit_channel,handle_deliver0,4,
[{file,"rabbit_channel.erl"},
{line,2728}]},
{lists,foldl,3,[{file,"lists.erl"},{line,1594}]},
{rabbit_channel,handle_cast,2,
[{file,"rabbit_channel.erl"},
{line,728}]},
{gen_server2,handle_msg,2,
[{file,"gen_server2.erl"},{line,1056}]},
{proc_lib,wake_up,3,
[{file,"proc_lib.erl"},{line,251}]}]}
```
This commit first gives `mc:init/3` the chance to set exchange and
routing_keys annotations.
If not set, `rabbit_stream_queue` will set these annotations assuming
the message was originally published via the stream protocol.
* Support consistent hash exchange routing for MQTT 5.0
When a consistent hash exchange is bound to the MQTT topic exchange,
MQTT 5.0 messages can be routed to queues consistently based on the
Correlation-Data in the PUBLISH packet.
* Convert MQTT 5.0 User Property
* to AMQP 0.9.1 headers
* from AMQP 0.9.1 headers
* to AMQP 1.0 application properties and message annotations
* from AMQP 1.0 application properties and message annotations
* Make use of Annotations in mc_mqtt:protocol_state/2
mc_mqtt:protocol_state/2 includes Annotations as parameter.
It's cleaner to make use of these Annotations when computing the
protocol state instead of relying on the caller (rabbitmq_mqtt_processor)
to compute the protocol state.
* Enforce AMQP 0.9.1 field name length limit
The AMQP 0.9.1 spec prohibits field names longer than 128 characters.
Therefore, when converting AMQP 1.0 message annotations, application
properties or MQTT 5.0 User Property to AMQP 0.9.1 headers, drop any
names longer than 128 characters.
* Fix type specs
Apply feedback from Michael Davis
Co-authored-by: Michael Davis <mcarsondavis@gmail.com>
* Add mc_mqtt unit test suite
Implement mc_mqtt:x_header/2
* Translate indicator that payload is UTF-8 encoded
when converting between MQTT 5.0 and AMQP 1.0
* Translate single amqp-value section from AMQP 1.0 to MQTT
Convert to a text representation, if possible, and indicate to MQTT
client that the payload is UTF-8 encoded. This way, the MQTT client will
be able to parse the payload.
If conversion to text representation is not possible, encode the payload
using the AMQP 1.0 type system and indiate the encoding via Content-Type
message/vnd.rabbitmq.amqp.
This Content-Type is not registered.
Type "message" makes sense since it's a message.
Vendor tree "vnd.rabbitmq.amqp" makes sense since merely subtype "amqp" is not
registered.
* Fix payload conversion
* Translate Response Topic between MQTT and AMQP
Translate MQTT 5.0 Response Topic to AMQP 1.0 reply-to address and vice
versa.
The Response Topic must be a UTF-8 encoded string.
This commit re-uses the already defined RabbitMQ target addresses:
```
"/topic/" RK Publish to amq.topic with routing key RK
"/exchange/" X "/" RK Publish to exchange X with routing key RK
```
By default, the MQTT topic exchange is configure dto be amq.topic using
the 1st target address.
When an operator modifies the mqtt.exchange, the 2nd target address is
used.
* Apply PR feedback

* Regenerate portions of deps/rabbit/app.bzl with gazelle
I'm not exactly sure how this happened, but gazell seems to have been
run with an older version of the rules_erlang gazelle extension at
some point. This caused generation of a structure that is no longer
used. This commit updates the structure to the current pattern.
* mc: refactoring
* mc_amqpl: handle delivery annotations
Just in case they are included.
Also use iolist_to_iovec to create flat list of binaries when
converting from amqp with amqp encoded payload.
