Sidekiq::MAJOR was added in mperham/sidekiq@b4092e3, which is only
included in 7.0.0+ so we can't use it to check the version for
Sidekiq 6.
Since the test code is written to support both, the condition should
also support both.
This commit adds `ActiveJob.deprecator` and replaces all usages of
`ActiveSupport::Deprecation.warn` in `activejob/lib` with
`ActiveJob.deprecator`.
Additionally, this commit adds `ActiveJob.deprecator` to
`Rails.application.deprecators` so that it can be configured via
settings such as `config.active_support.report_deprecations`.
This commit also removes a defunct `ActiveSupport::Deprecation.silence`
call that was added in 9eb4b4ed01f893c2fc7ff3ee4f99301dec7ea3c2 but not
removed when the deprecation was completed in
10bd5e59c3291bb2034869e97cca30634a559afb.
I noticed a difference in behavior when inspecting `ActiveJob::Core#scheduled_at` in non-test environments vs when inspecting in while executing tests.
Prior to this change, `ActiveJob::TestHelper` would set `ActiveJob::Core#scheduled_at` to a `Time` object in tests,
however this attribute was set to a `Float` objects in non-test environments:
<d1aa6af5cc/activejob/lib/active_job/core.rb (L161)>
This change ensures parity in all runtime environments.
We recently let a few very easy to avoid warnings get merged.
The root cause is that locally the test suite doesn't run in
verbose mode unless you explictly pass `-w`.
On CI warnings are enabled, but there is no reason to look at the
build output unless something is failing. And even if one wanted
to do that, that would be particularly work intensive since warnings
may be specific to a Ruby version etc.
Because of this I believe we should:
- Always run the test suite with warnings enabled.
- Raise an error if a warning is unexpected.
We've been using this pattern for a long time at Shopify both in private
and public repositories.
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.
The Active Job integration tests for Que and Queue Classic assume a
connection to a PostgreSQL database running on localhost:5432 since the
psql command to create the databases does not pass the -h and -p options.
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.
Replace Que.* settings that were removed in Que 1.0 with options passed
to Que::Locker. The Locker class creates its own thread for managing
work distribution, so the Thread created in the QueJobsManager was also
removed.
Using `assert` by itself without an error message leads to test output
like the following:
```
Failure:
QueuingTest#test_current_timezone_is_kept_while_running_perform_later [.../rails/activejob/test/integration/queuing_test.rb:118]:
Expected false to be truthy.
```
These added helpers provide a more specific error message so that the
reasons for test failures become more clear:
```
Failure:
QueuingTest#test_current_timezone_is_kept_while_running_perform_later [.../rails/activejob/test/integration/queuing_test.rb:118]:
Job AJ-63fe8bf6-7062-4a56-a10a-97c37fcaa6e6 was not executed
```
Fixing the synchronous setting uncovered some more errors with Que 1.0:
exception tests with retry_on started failing due to an assertion in
Que's Active Job integration that running jobs won't nest. However, this
is not the case when running retriable jobs synchronously.
This change overrides Que's Active Job wrapper to not make this
assertion.
I also opened an issue in the que repo: https://github.com/que-rb/que/issues/329
Que.mode was removed in 6783fdd68a
and replaced by Que.run_synchronously = true per changelog:
fa4988ee33/CHANGELOG.md (L120)
It looks like it started failing because Que 1.0 was released yesterday.
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.
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.
This commit restores the test deleted in
cd22ecbfc2
Active Job should not test things about autoloading, this would
belong to the railties test suite probably. However, there, it feels
a bit too distant from here.
Imperfect, but on a second thought I believe this trade-off is better.
I found an unexpected use of assertion in the block of `assert_raise`
when I implemented https://github.com/rubocop/rubocop-minitest/pull/137.
It is expected to be asserted after an exception is raised in
`assert_raise` block, but in actually it is not asserted after an
exception is raised. Therefore, this PR removes or updates assertions
that have not been asserted after an exception has raised.
This PR will add `rubocop-minitest` and enable
`Minitest/UnreachableAssertion` cop to able similar auto-detection,
but will remove `rubocop-minitest` from this PR if you don't like it.

AJ infers adapater class names, and loads them. How are those classes made
available to AJ is a user's concern.
Perhaps they loaded the adapter with require, perhaps they have the class in the
autoload_once_paths. It does not matter, it is the user responsibility to make
the class available _somehow_, and AJ can assume that.
In some applications, some classes of errors may be raised during the
execution of a job which the developer would want to retry forever.
These classes of errors would most likely be infrastructure problems that
the developer knows will be resolved eventually but may take a variable
amount of time or errors where due to application business logic, there
could be something temporarily blocking the job from executing, like a
resource that is needed for the job being locked for a lengthy amount of
time.
While an arbitrarily large number of attempts could previously be passed,
this is inexpressive as sometimes the developer may just need the job to
continue to be retried until it eventually succeeds. Without this,
developers would need to include additional code to handle the situation
where the job eventually fails its attempts limit and has to be re-enqueued
manually.
As with many things this should be used with caution and only for errors
that the developer knows will definitely eventually be resolved, allowing
the job to continue.
[Daniel Morton + Rafael Mendonça França]
There is presently no clean way of telling a caller of `perform_later`
the reason why a job failed to enqueue. When the job is enqueued
successfully, the job object itself is returned, but when the job can
not be enqueued, only `false` is returned. This does not allow callers
to distinguish between classes of failures.
One important class of failures is when the job backend experiences a
network partition when communicating with its underlying datastore. It
is entirely possible for that network partition to recover and as such,
code attempting to enqueue a job may wish to take action to reenqueue
that job after a brief delay. This is distinguished from the class of
failures where due a business rule defined in a callback in the
application, a job fails to enqueue and should not be retried.
This PR changes the following:
- Allows a block to be passed to the `perform_later` method. After the
`enqueue` method is executed, but before the result is returned, the
job will be yielded to the block. This allows the code invoking the
`perform_later` method to inspect the job object, even in failure
scenarios.
- Adds an exception `EnqueueError` which job adapters can raise if they
detect a problem specific to their underlying implementation or
infrastructure during the enqueue process.
- Adds two properties to the job base class: `successfully_enqueued` and
`enqueue_error`. `enqueue_error` will be populated by the `enqueue`
method if it rescues an `EnqueueError` raised by the job backend.
`successfully_enqueued` will be true if the job is not rejected by
callbacks and does not cause the job backend to raise an
`EnqueueError` and will be `false` otherwise.
This will allow developers to do something like the following:
MyJob.perform_later do |job|
unless job.successfully_enqueued?
if job.enqueue_error&.message == "Redis was unavailable"
# invoke some code that will retry the job after a delay
end
end
end
Before this commit, only StandardError exceptions can be handled by
rescue_from handlers.
This changes the rescue clause to catch all Exception objects, allowing
rescue handlers to be defined for Exception classes not inheriting from
StandardError.
This means that rescue handlers that are rescuing Exceptions outside of
StandardError exceptions may rescue exceptions that were not being
rescued before this change.

The implementaiton of `instrument` in `ActiveJob::Instrumentation` was
not keeping the API of `ActiveSupport::Notification.instrument` and
returning the value of the block.
Fixes#40931.
Before #34953, when using the `:async` Active Job queue adapter, jobs
enqueued in `db/seeds.rb`, such as Active Storage analysis jobs, would
cause a hang (see #34939). Therefore, #34953 changed all jobs enqueued
in `db/seeds.rb` to use the `:inline` queue adapter instead. (This
behavior was later limited to only take effect when the `:async` adapter
was configured, see #35905.) However, inline jobs in `db/seeds.rb`
cleared `CurrentAttributes` values (see #37526). Therefore, #37568
changed the `:inline` adapter to wrap each job in its own thread, for
isolation. However, wrapping a job in its own thread affects which
database connection it uses. Thus inline jobs can no longer execute
within the calling thread's database transaction, including seeing any
uncommitted changes. Additionally, if the calling thread is not wrapped
with the executor, the inline job thread (which is wrapped with the
executor) can deadlock on the load interlock. And when testing (with
`connection_pool.lock_thread = true`), the inline job thread can
deadlock on one of the locks added by #28083.
Therefore, this commit reverts the solutions of #34953 and #37568, and
instead wraps evaluation of `db/seeds.rb` with the executor. This
eliminates the original hang from #34939, which was also due to running
multiple threads and not wrapping all of them with the executor. And,
because nested calls to `executor.wrap` are ignored, any inline jobs in
`db/seeds.rb` will not clear `CurrentAttributes` values.
Alternative fix for #34939.
Reverts #34953.
Reverts #35905.
Partially reverts #35896.
Alternative fix for #37526.
Reverts #37568.

PR #33995 added support for specifying the `args` argument of
`assert_enqueued_with` and `assert_performed_with` as a matcher proc.
In doing so, it added undocumented support for specifying the other
arguments as matcher procs as well. This commit officially documents
that support, and adds tests to ensure the behavior.
assert_enqueued_with with a block ignores all the jobs enqueued before
the block for its assertions by counting the number of jobs and dropping
the n first elements from the Array, but since we're now mutating the
Array in perform_enqueued_jobs without a block, it's broken.
This uses another implementation which is correct when the array is
mutated, by getting a duplicated array of jobs, then removing them from
the original array.
Similarly assert_enqueued_jobs with a block was using counts only, now
keeps track of the specific jobs to count them at the end.
This makes sure jobs don't run twice if `perform_enqueued_jobs` is
called twice without a block.
This also mimics the behavior of using `perform_enqueued_jobs` with a
block, where at the end of the block performed jobs are not in
`enqueued_jobs` but instead in `performed_jobs`.
- ### Problem
If we use `perform_enqueued_jobs` without a block, a job that
uses a retry mechanism to reeenqueue itself would get performed
right away.
This behaviour make sense when using `perform_enqueued_jobs` with
a block.
However I'm expecting `perform_enqueued_jobs` without a block to
perform jobs that are **already** in the queue not the ones that
will get enqueued afterwards.
### Solution
Dup the array of jobs given to avoid future mutation.
- ### Problem
If we use `perform_enqueued_jobs` without a block,
a job that raises an error wouldn't be appended to
the list of `performed_jobs`.
### Solution
Push the job in the array before it is actually performed.

Randomize jitter
- This PR attempts to fix a problem with ActiveJob jitter where the `determine_jitter_for_delay` value may not always be randomized. Especially when the jitter delay multplier is between 1 and 2 it always returns 0.
- With this change, we pass a range to `Kernel.rand` beginning with 0 to the `jitter_multiplier`. With positive float values, the return value will be a random float number from the range.
- Includes test cases to verify random wait time when the jitter_multiplier is between 1 and 2.
- Updated relevant test cases stubbing the `Kernel.rand` method, refactored some by removing unwanted stubs for `Kernel.rand` method where jitter is falsey.

- Instead of using Kernel.rand with range, used simple multiplication with Kernel.rand for calculating delay for jitter
- Updates to the tests according to changes
- ### Problem
In some cirumstances, the deprecation message to warn that AJ won't
run `after_(enqueue/perform)` callbacks when the chain is halted
by a `throw(:abort)` will be thrown even though no `throw(:abort)`
was thrown.
```ruby
run_callback(:foo) do
...
end
```
There is two possible way for the callback body to not be executed:
1) `before` callback throw a `abort`
2) `before` callback raises an error which is rescued by an
around callback (See associated test in this commit for
an example)
When 2) happen we don't want to output a deprecation message,
because what the message says isn't true and doesn't apply.
### Solution
In order to differentiate between 1) and 2), I have added
a `halted_callback_hook` which is called by ActiveSupport callback
whenever the callback chain is halted.
- ### Problem
Given the below example the test adapter will retry the job
indefinitely:
```ruby
class BuggyJob < ActiveJob::Base
retry_on(Exception, attempts: 2)
def perform
raise "error"
end
end
BuggyJob.perform_later
perform_enqueued_jobs
```
The problem is that when the job get retried, the
`exception_executions` variable is not serialized/deserialized,
resulting in ActiveJob to not be able to determine how many time
this job was retried.
The solution in this PR is to deserialize the whole job in the test
adapter, and reserialize it before retrying.
Fix#38391
- I made a change in 0d3aec49695 to output a log if a job was aborted
in a before callbacks. I didn't take in consideration that a job
could return a falsy value and thus it would wrongly log
that the job was aborted.
This fixes the problem by checking if the callback chain was halted
rather than the return value of the job.
- Since this is going to be the default in 6.1, let's set it in the
test suite to avoid deprecation warning.
Otherwise one has to do `AS::Deprecation.silence { }` everytime we
add a new test.
Fix#38107
* Add failing ActiveJob exceptions test for "disable retry jitter"
Thanks to @kaspth for the starting point.
* Update ActiveJob retry jitter to correctly use zero value
* Simplify "disable retry jitter" test
We don't need to repeat this many times. Fewer is shorter.
* Refactor determine_delay with jitter
* Fix indentation
* Close the curtains and give JITTER_DEFAULT some privacy
* Use .zero? instead of == to check jitter value
* Add ActiveJob test for explicit zero jitter

The existing message only mentioned one type of before/after callback,
but the config was named generally. That mismatch is confusing and users
wouldn't necessarily know what the total effect of the config would be.
So instead of handwriting the deprecation warning in the specific instances,
consolidate it in one place and give the appropriate context. That context
is the above, but also that users shouldn't update their app config,
they should uncomment the line in the new defaults file, which now also
has more context.
I'm not totally convinced that we can't move this to when
`after_enqueue`/`after_perform` is called in the job class. Doesn't
seem worth it to blare this after every job enqueue/perform, when we
the score at boot time.

### Problem
In rails/rails@bbfab0b33a I introduced a change which outputs
a deprecation whenever a class inherits from ActiveJob::Base.
This has the negative effect to trigger a massive amount of
deprecation at boot time especially if your app is eagerloaded
(like it's usually the case on CI).
Another issue with this approach was that the deprecation will
be output no matter if a job define a `after_perform` callbacks
i.e.
```ruby
class MyJob < AJ::Base
before_enqueue { throw(:abort) }
end
# This shouldn't trigger a deprecation since no after callbacks are defined
# The change in 6.2 will be already safe for the app.
```
### Solution
Trigger the deprecation only when a job is abort
(during enqueuing or performing) AND a `after_perform`
callback is defined on the job.
- ### Problem
```ruby
MyJob < ApplicationJob
before_enqueue { throw(:abort) }
after_enqueue { # enters here }
end
```
I find AJ behaviour on after_enqueue and after_perform callbacks
weird as they get run even when the callback chain is halted.
It's counter intuitive to run the after_enqueue callbacks even
though the job wasn't event enqueued.
### Solution
In Rails 6.2, I propose to make the new behaviour the default
and stop running after callbacks when the chain is halted.
For application that wants this behaviour now or in 6.1
they can do so by adding the `config.active_job.skip_after_callbacks_if_terminated = true`
in their configuration file.
- ### Problem
ActiveJob will always log "Enqueued MyJob (Job ID) ..." even
if the job doesn't get enqueued through the adapter.
Same problem happens when performing a Job, "Performed MyJob (Job ID) ..." will be logged even when job wasn't performed at all.
This situation can happen either if the callback chain is terminated
(before_enqueue throwing an `abort`) or if an exception is raised.
### Solution
Check if the callback chain is aborted/exception is raised, and log accordingly.
Prior to this change, exponentially_longer had adverse consequences
during system-wide downstream failures. This change adds a random value to the
back off calculation in order to prevent the thundering herd
problem, whereby all retry jobs would retry at the same time.
Specifically this change adds a jitter option to retry_on to enable users of it to
scope the randomness calculation to a reasonable amount. The default is
15% of the exponential back off calculation.
class SensitiveJob < ApplicationJob
self.log_arguments = false
def perform(my_sensitive_argument)
end
end
When dealing with sensitive arugments as password and tokens it is
now possible to configure the job to not put the sensitive argument
in the logs.
Closes#34438.
Using `self` works by essentially pointing to the included class, in
this case `ActiveJob::Base`, so that'd end up delegating to
`ActiveJob::Base.queue_adapter` instead.
This commit allows ActiveJob to serialize classes and modules without a custom serializer. This allows for workflows like:
```
class EmailJob < ApplicationJob
queue_as :default
def perform(template_class, *arguments)
template_class.new(*arguments).send!
end
end
module Email
class FooTemplate ... end
class BarTemplate ... end
end
EmailJob.perform_later(Email::FooTemplate, ...)
EmailJob.perform_later(Email::BarTemplate, ...)
```
Currently this is only achieveable through a custom serializer or through constantizing in each instance.
The `Sidekiq::Logging` module was removed in Sidekiq 6.0 in favour of
`Sidekiq.logger=`.
