enqueue_at and enqueue_in should respect COMMIT_MODE

[selwin]

Fixes #821

Summary by CodeRabbit

• New Features
  • Job enqueueing now consistently supports automatic, database-commit, and request-finished execution modes.
  • Jobs submitted with an explicit pipeline execute immediately.
  • Immediate and scheduled job submissions now follow the same deferral behavior.
  • Deferred jobs are reliably dispatched after successful commits and remain unqueued after rollbacks.
• Tests
  • Expanded coverage for commit modes, nested transactions, scheduled jobs, pipelines, and job-stop actions.

📝 Walkthrough

Walkthrough

Django RQ now applies commit-mode handling to job and scheduler enqueue APIs through shared dispatch logic. Deferred entries retain their RQ method, and tests cover immediate, scheduled, pipeline, request, commit, rollback, and nested transaction behavior.

Changes

Commit-mode enqueueing

Layer / File(s)	Summary
Unified enqueue dispatch django_rq/queues.py	DjangoRQ routes enqueue_job and enqueue_at through shared commit-mode logic. enqueue_call now delegates to RQ while enqueue_now flushes deferred methods immediately.
Deferred queue method dispatch django_rq/thread_queue.py	Deferred entries now store (queue, method_name, args, kwargs) and replay the selected RQ method through enqueue_now.
Enqueue behavior validation tests/test_commit_modes.py, tests/test_django_rq_utils.py, tests/test_views.py, tests/test_views.py	Tests cover queue and scheduler APIs across commit modes, explicit pipelines, transactions, rollbacks, requests, and delayed scheduling. The view fixtures enqueue delayed jobs for scheduler coverage.

Merge Risk: 🟠 High · up to 59d2c

The reworked enqueue path passes an argument that the supported queue library version does not accept, so background jobs would fail to be enqueued in all commit modes. This should be corrected before merge.

Explanation

The rewrite of tests/test_views.py::test_action_stop_jobs changes stop-job test execution and mocking. It does not support COMMIT_MODE for enqueue_at or enqueue_in, and it is unrelated to issue #821. The other reviewed changes have a direct connection to the scheduler behavior or its tests.

Remove the unsupported unique argument.

pyproject.toml permits RQ 2.6.1, whose Queue.enqueue_job accepts only job, pipeline, and at_front. This override forwards unique=False to that method, which can raise TypeError in auto mode and when deferred calls flush through enqueue_now.

-def enqueue_job(self, job, pipeline=None, at_front=False, unique=False, **kwargs):
-    return self._enqueue_or_defer('enqueue_job', job, pipeline=pipeline, at_front=at_front, unique=unique, **kwargs)
+def enqueue_job(self, job, pipeline=None, at_front=False):
+    return self._enqueue_or_defer('enqueue_job', job, pipeline=pipeline, at_front=at_front)

RQ 2.6.1 rq.command.send_stop_job_command signature

💡 Result:

<search_synthesis>
The signature for the rq.command.send_stop_job_command function in the RQ (Redis Queue) library is as follows: send_stop_job_command(connection, job_id) Parameters: 1. connection: An instance of a Redis connection (typically from the redis-py library) [1][2]. 2. job_id: The unique identifier (string) of the job that is currently being executed by a worker [1][3]. Functionality: This function is used to signal a worker to immediately stop a job that is currently in an executing state [1][4]. When successfully triggered, the job is moved to the FailedJobRegistry [1][4]. If the specified job is not currently executing (i.e., it is queued, finished, or deferred), the function will raise an InvalidJobOperation exception [1][3].

I.e. I will launch job1, and then later call `queue.enqueue(job2, ..., depends_on=job1)`. The issue I&`#39`;m currently hitting is that I have launched job1 without any timeout, and it has somewhat silently failed meaning it is not exiting and is instead just running forever in the queue. At this point, I now have a job2 that is in `deferred` state waiting for job1 to complete (which it never will). I ran `send_stop_job_command()` on job1 to kill it, which worked and it is no longer in the queue. However, job2 is still in `deferred` state and is not getting queued. I cannot kill this job by running `send_stop_job_command()`, I get: ``` send_stop_job_command(..., job.id) --------------------------------------------------------------------------- InvalidJobOperation Traceback (most recent call last) ... /opt/conda/envs/kg/lib/python3.6/site-packages/rq/command.py in send_stop_job_command(connection, job_id) 37 job = Job.fetch(job_id, connection=connection) 38 if not job.worker_name: ---> 39 raise InvalidJobOperation(&`#39`;Job is not currently executing&`#39`;) 40 send_command(connection, job.worker_name, &`#39`;stop-job&`#39`;, job_id=job_id) 41 InvalidJobOperation: Job is not currently executing ``` Is there some sort of workaround for killing jobs that are in `deferred` state? ## Timeline - Renamed from "Cannot stop deferred jobs that have not been enqueued" to "InvalidJobOperation: Job is not currently executing when attempting to stop deferred jobs" **selwin** commented on 2021-02-09T01:40:29Z: > If job is in the deferred state, you can call `job.cancel()`. **JLHasson** commented on 2021-03-08T18:38:03Z: > Thanks `@selwin`!

It is backed by Redis/Valkey and is designed to have a low barrier to entry. It integrates easily with your web or application stack. RQ requires Redis >= 5 or Valkey >= 7.2. ## Getting Started First, run a Redis/Valkey server. To put jobs on queues, you don’t have to do anything special, just define your typically lengthy or blocking function: ``` import requests def count_words_at_url(url): resp = requests.get(url) return len(resp.text.split()) ``` Then, create a RQ queue: ``` from redis import Redis from rq import Queue q = Queue(connection=Redis()) ``` And enqueue the function call: ``` from my_module import count_words_at_url result = q.enqueue(count_words_at_url, &`#39`;https://python-rq.org&`#39`;) ``` ### Scheduling Jobs Scheduling jobs are similarly easy: ``` # Schedule job to run at 9:15, October 10th job = queue.enqueue_at(datetime(2019, 10, 8, 9, 15), say_hello) # Schedule job to be run in 10 seconds job = queue.enqueue_in(timedelta(seconds=10), say_hello) ``` ## Repeating Jobs To repeat jobs multiple times: ``` from rq.repeat import Repeat # Repeat job 3 times after successful completion, with 60 second intervals job = queue.enqueue(say_hello, repeat=Repeat(times=3, interval=60)) # Use different intervals between repetitions job = queue.enqueue(say_hello, repeat=Repeat(times=3, interval=[10, 30, 60])) ``` Note that jobs will only repeat after successful executions. To retry failed jobs, use `Retry`. ### Retrying Failed Jobs You can also ask RQ to retry failed jobs: ``` from rq import Retry # Retry up to 3 times, failed job will be requeued immediately queue.enqueue(say_hello, retry=Retry(max=3)) # Retry up to 3 times, with configurable intervals between retries queue.enqueue(say_hello, retry=Retry(max=3, interval=[10, 30, 60])) ``` ### The Worker To start executing enqueued function calls in the background, start a worker from your project’s directory: ``` $ rq worker --with-scheduler *** Listening for work on default Got count_words_at_url(&`#39`;http://nvie.com&`#39`;) from default Job result = 818 *** Listening for work on default ``` That’s about it. ## Installation Simply use the following command to install the latest released version: ``` pip install rq ``` ## High Level Overview There are several important concepts in RQ: 1. `Queue`: contains a list of `Job` instances to be executed in a FIFO manner. 2. `Job`: contains the function to be executed by the worker. 3. `Worker`: responsible for getting `Job` instances from a `Queue` and executing them. 4. `Execution`: contains runtime data of a `Job`, created by a `Worker` when it executes a `Job`. 5. `Result`: stores the outcome of an `Execution`, whether it succeeded or failed. ## Project History This project has been inspired by the good parts of Celery, Resque and this snippet, and has been created as a lightweight alternative to existing queueing frameworks, with a low barrier to entry. RQ is maintained by Stamps, an Indonesian CRM company. It is open sourced under the terms of the BSD license.

send_stop_job_command has the (connection, job_id) contract, but the test checks only job_id. A wrong Redis connection would pass.
