We already were using Cowlib 2.12.1 and therefore were
compatible with OTP-26. This simply updates Cowboy to
the version that depends on Cowlib 2.12.1.
This change should be reverted once emqx/emqtt is OTP26 compatible.
Our fork/branch isn't either at this point, but at least partially
works. Let's use this branch for now to uncover server-side OTP26
incompatibilities (and continue working on OTP26 support for emqtt of
course).
* Fetch all prod cli deps with bazel
This avoids issues with hex and OTP 26, and is needed for offline
bazel builds anyway
* Fetch test cli deps with bazel
* mix format
Previously osiris did not support uncorrelated writes which means
we could not use a "stateless" queue type delivery and these were
silently dropped.
This had the impact that at-most-once dead letter was not possible
where the dead letter target is a stream.
This change bumps the osiris version that has the required API
to allow for uncorrelated writes (osiris:write/2).
Currently there is no feature flag to control this as osiris writer
processes just logs and drops any messages they don't understand.
Returns reaching a Ra member that used to be leader but now has stepped
down would cause that follower to crash and restart.
This commit avoids this scenario as well as giving the return commands
a good chance of being resent to the new leader in a timeley manner.
(see the Ra release for this).
deps/rabbitmq_ct_helpers depends on proper and meck, so unfortunately
if proper and meck are marked as dev dependencies, bazel modules
depending on rabbitmq-server cannot build it
Another way of putting it is that they are not actually "dev"
dependencies of for all components that rabbitmq-server exposes
This Ra release includes improvements to Ra server GC behaviour when receiving a lot
of low priority commands with large binary payloads (e.g. quorum queue messages).
Practically this allows quorum queues to accept large amounts of messages in a more predicatble and performant manner.
This change also removes ra_file_handle cache that was used as a bridge between ra file operations and RabbitMQ io metrics. Lots of components in RabbitMQ such as streams and CQv2s do not record io metrics in the previous manner due to overhead incurred for every file io operation. These metrics are better inspected at the OS level anyway.
This Ra release
* Omproves election availability in certain mixed versions failure
scenarios
* Optimises segment reference compaction which may becomes expensive
in quorum queues with very long backlogs
* Various log message improvements and level tweaks
* Better cleans up machine monitor records after quorum queue rebalancing
