The various LogSubscriber subclasses tend to subscribe to events
but then end up doing nothing if the log level is high enough.
But even if we end up not logging, we have to go through the
entire notification path, record timing etc.
By allowing subscribers to dynamically bail out early, we can
save a lot of work if all subscribers are silenced.
Previously configs of the form `config.active_job.X` were only forwarded to
`ActiveJob::Base`. This teaches Active Job to set them on `ActiveJob` directly
instead, if the setter exists.
For consistency, this more or less mirrors the way that Active Record does it.

Fix use_big_decimal_serializer Rails 7.1 default
This config should be enabled for new Rails 7.1 apps, or apps that have updated
their config to `load_defaults 7.1`, not disabled.
This also clarifies the config accessor comment.
---
Add contributor documentation comment to load_defaults
The process for introducing a change in behavior in Rails can be confusing to
new contributors, so a comment is added roughly explaining how to do so, and
what belongs in `load_defaults` and `new_framework_defaults`.
This comment is aimed at contributors, not consumers, so it is added within the
method, rather than above it.
Print default parent class for controller, job, and model generators.
Before:
[--parent=PARENT] # The parent class for the generated job
After:
[--parent=PARENT] # The parent class for the generated job
# Default: ApplicationJob
Previously, BigDecimal was listed as not needing a serializer. However,
when used with an adapter storing the job arguments as JSON, it would get
serialized as a simple String, resulting in deserialization also producing
a String (instead of a BigDecimal).
By using a serializer, we ensure the round trip is safe.
During upgrade deployments of applications with multiple replicas making use of
BigDecimal job arguments with a queue adapter serializing to JSON, there exists
a possible race condition, whereby a "new" replica enqueues a job with an
argument serialized using `BigDecimalSerializer`, and an "old" replica fails to
deserialize it (as it does not have `BigDecimalSerializer`).
Therefore, to ensure safe upgrades, serialization will not use
`BigDecimalSerializer` until `config.active_job.use_big_decimal_serializer` is
enabled, which can be done safely after successful deployment of Rails 7.1.
This option will be removed in Rails 7.2, when it will become the default.
This adds `:db_runtime` to `perform.active_job` notification payloads,
which is the total time taken by database queries while performing a
job. This value can be used to better understand how a job's time is
spent.
This is similar to the `:db_runtime` value added to
`process_action.action_controller` notification payloads by
`ActiveRecord::Railties::ControllerRuntime`.
Closes#35354.

que 1.2 introduced a deprecation warning when specifying job options
directly within the `#enqueue` method. From 1.2 job options need to be
provided as a hash in `job_options` keyword argument.
que 1.x is not compatible with Ruby 3 yet. que 2 will be.
This commit resolves the deprecation warning and ensures future
compatibility with que 2, allowing path to Ruby 3 upgrade preserving
compatibility with que 1.0.

RDoc will automatically format and link API references as long as they
are not already marked up as inline code.
This commit removes markup from various API references so that those
references will link to the relevant API docs.
`config.active_record.destroy_association_async_job` should allow applications
to specify the job that will be used to destroy associated records in the
background for `has_many` associations with the `dependent: :destroy_async`
option. That's being ignored, which means the default
`ActiveRecord::DestroyAssociationAsyncJob` always destroys records in the
background. This change stops ignoring the configuration.
In other log messages like perform/performed and ActiveJob error logging, the job ID and exception message were already included, eg:
Error performing TestFailureJob (Job ID: d70ad13e-e58b-409c-a8cc-e0447fc792b5) from Resque(default) in 1446.56ms: RuntimeError (Error Message):
But log message related to retry/discard behavior from ActiveJob::Exceptions did not include the Job ID or exception message. We now include them, in a consistent format with other existing messages.
Job ID is especially useful because, while other ActiveJob-related log messages get the Job ID via tagged logging, retry-related log messages do not currently end up tagged with Job ID. And it's really useful to use Job ID to be able to collect all the log lines related to a particular job, put the error messages together with the retry and subsequent perform messages.
We also include job.executions in the enqueue_retry log message because it was available and useful, to know if this is the 1st retry or 2nd or whatever. Previously job.executions was included in retry_stopped logging, but not enqueue_retry.
I'm working on a standardized error reporting interface
(https://github.com/rails/rails/issues/43472) and it has the same need
for a `context` than Active Record's query logs.
Just like query logs, when reporting an error you want to know what the
current controller or job is, etc.
So by extracting it we can allow both API to use the same store.
Error messages from assert_enqueued_with and assert_performed_with
shows which other jobs are enqueued or performed when you get an
error. We can improve these messages to make it clearer why the job
didn't match. This one error messages now have three different formats
based on why the job didn't match
1. Didn't match because no jobs are queued at all. This now reports,
```
No performed job found with {:job=>HelloJob, :args=>[]}
No jobs where performed
```
2. Didn't match because that job class was not queued. This now reports,
```
No performed job found with {:job=>MultipleKwargsJob, :args=>[#<Person:0x00007fe38f9f8100 @id=11>]}
No jobs of class MultipleKwargsJob where performed, job classes performed: HelloJob
```
3. Doesn't match due to arguments, queue, priority or other reason. This now reports
```
No performed job found with {:job=>HelloJob, :args=>[#<Person:0x00007fe3a89fc2c8 @id=11>]}
Potential matches: {"job_class"=>"HelloJob", "job_id"=>"f8636fd9-c7a0-4565-9198-17e175f30f0e", "provider_job_id"=>nil, "queue_name"=>"default", "priority"=>nil, "arguments"=>[{"_aj_globalid"=>"gid://aj/Person/9"}], "executions"=>0, "exception_executions"=>{}, "locale"=>"en", "timezone"=>nil, "enqueued_at"=>"2021-10-27T23:19:54Z", :job=>HelloJob, :args=>[#<Person:0x00007fe3a89dce00 @id="9">], :queue=>"default", :priority=>nil}
```
Which matches the old error message, but only reports jobs that where
queued of the same class as the job you are asserting was queued.
This remove the null object as discussed in
8af78700d2.
Since it pretends to be nil but acts as thruthy in boolean context
it cause more confusion than it clean code.
`update_context` is removed in favor of `set_context` without
a block.
The ModuleSerializer does not support serializing anonymous classes
because when we try to deserialize the anonymous class, it wouldn't
know which class to use (since class name is nil).
For this reason, ModuleSerialzier now raises an error if the class
name is nil. Previously, ModuleSerializer would raise an `undefined
method `constantize' for nil:NilClass` error during deserialization.
It's not clear why the deserialization failed from the error.
In this commit, we raise an explicit error when trying to serialize
an anonymous class indicating this behaviour is not supported.
Previously in `perform_enqueued_jobs`, `deserialize_arguments_if_needed`
was called before calling `perform_now`. When a record no longer exists
and is serialized using GlobalID this led to raising
an `ActiveJob::DeserializationError` before reaching `perform_now` call.
This behaviour makes difficult testing the job `discard_on/retry_on` logic.
Now `deserialize_arguments_if_needed` call is postponed to when `perform_now`
is called.
Example:
```ruby
class UpdateUserJob < ActiveJob::Base
discard_on ActiveJob::DeserializationError
def perform(user)
# ...
end
end
User.destroy_all
assert_nothing_raised do
perform_enqueued_jobs only: UpdateUserJob
end
assert_no_enqueued_jobs
```
Before this changes the test will fail, now it passes.
