1.0 (2019-04-06)

Backward incompatible changes:

  • job.status has been removed. Use job.get_status() and job.set_status() instead. Thanks @selwin!

  • Fix: Queue.empty() now correctly deletes job hashes from Redis.

0.3.13

(December 17th, 2013)

  • Bug fix where the worker crashes on jobs that have their timeout explicitly removed. Thanks for reporting, @algrs.

0.3.12

(December 16th, 2013)

  • Bug fix where a worker could time out before the job was done, removing it from any monitor overviews (#288).

0.3.11

(August 23th, 2013)

  • Some more fixes in command line scripts for Python 3

0.3.10

(August 20th, 2013)

  • Bug fix in setup.py

0.3.9

(August 20th, 2013)

  • Python 3 compatibility (Thanks, Alex!)

  • Minor bug fix where Sentry would break when func cannot be imported

0.3.8

(June 17th, 2013)

  • rqworker and rqinfo have a --url argument to connect to a Redis url.

  • rqworker and rqinfo have a --socket option to connect to a Redis server through a Unix socket.

  • rqworker reads SENTRY_DSN from the environment, unless specifically provided on the command line.

  • Queue has a new API that supports paging get_jobs(3, 7), which will return at most 7 jobs, starting from the 3rd.

(February 26th, 2013)

  • Fixed bug where workers would not execute builtin functions properly.

0.3.6

(February 18th, 2013)

  • Worker registrations now expire. This should prevent rqinfo from reporting about ghosted workers. (Thanks, @yaniv-aknin!)

  • rqworker will automatically clean up ghosted worker registrations from pre-0.3.6 runs.

  • rqworker grew a -q flag, to be more silent (only warnings/errors are shown)

0.3.5

(February 6th, 2013)

  • ended_at is now recorded for normally finished jobs, too. (Previously only for failed jobs.)

  • Adds support for both Redis and StrictRedis connection types

  • Makes StrictRedis the default connection type if none is explicitly provided

0.3.4

(January 23rd, 2013)

  • Restore compatibility with Python 2.6.

0.3.3

(January 18th, 2013)

  • Fix bug where work was lost due to silently ignored unpickle errors.

  • Jobs can now access the current Job instance from within. Relevant documentation here.

  • Custom properties can be set by modifying the job.meta dict. Relevant documentation here.

  • Custom properties can be set by modifying the job.meta dict. Relevant documentation here.

  • rqworker now has an optional --password flag.

  • Remove logbook dependency (in favor of logging)

0.3.2

(September 3rd, 2012)

  • Fixes broken rqinfo command.

  • Improve compatibility with Python < 2.7.

0.3.1

(August 30th, 2012)

  • .enqueue() now takes a result_ttl keyword argument that can be used to change the expiration time of results.

  • Queue constructor now takes an optional async=False argument to bypass the worker (for testing purposes).

  • Jobs now carry status information. To get job status information, like whether a job is queued, finished, or failed, use the property status, or one of the new boolean accessor properties is_queued, is_finished or is_failed.

  • Jobs return values are always stored explicitly, even if they have to explicit return value or return None (with given TTL of course). This makes it possible to distinguish between a job that explicitly returned None and a job that isn't finished yet (see status property).

  • Custom exception handlers can now be configured in addition to, or to fully replace, moving failed jobs to the failed queue. Relevant documentation here and here.

  • rqworker now supports passing in configuration files instead of the many command line options: rqworker -c settings will source settings.py.

  • rqworker now supports one-flag setup to enable Sentry as its exception handler: rqworker --sentry-dsn="http://public:[email protected]/1" Alternatively, you can use a settings file and configure SENTRY_DSN = 'http://public:[email protected]/1' instead.

0.3.0

(August 5th, 2012)

  • Reliability improvements

    • Warm shutdown now exits immediately when Ctrl+C is pressed and worker is idle
    • Worker does not leak worker registrations anymore when stopped gracefully

  • .enqueue() does not consume the timeout kwarg anymore. Instead, to pass RQ a timeout value while enqueueing a function, use the explicit invocation instead:

    ```python
q.enqueue(do_something, args=(1, 2), kwargs={'a': 1}, timeout=30)
```

  • Add a @job decorator, which can be used to do Celery-style delayed invocations:

    ```python
from redis import StrictRedis
from rq.decorators import job

# Connect to Redis
redis = StrictRedis()

@job('high', timeout=10, connection=redis)
def some_work(x, y):
    return x + y
```

    Then, in another module, you can call some_work:

    ```python
from foo.bar import some_work

some_work.delay(2, 3)
```

0.2.2

(August 1st, 2012)

  • Fix bug where return values that couldn't be pickled crashed the worker

0.2.1

(July 20th, 2012)

  • Fix important bug where result data wasn't restored from Redis correctly (affected non-string results only).

0.2.0

(July 18th, 2012)

  • q.enqueue() accepts instance methods now, too. Objects will be pickle'd along with the instance method, so beware.
  • q.enqueue() accepts string specification of functions now, too. Example: q.enqueue("my.math.lib.fibonacci", 5). Useful if the worker and the submitter of work don't share code bases.
  • Job can be assigned custom attrs and they will be pickle'd along with the rest of the job's attrs. Can be used when writing RQ extensions.
  • Workers can now accept explicit connections, like Queues.
  • Various bug fixes.

0.1.2

(May 15, 2012)

  • Fix broken PyPI deployment.

0.1.1
