Raw Blame History

### 0.12.0 (2018-07-14)
- Added support for Python 3.7. Since `async` is a keyword in Python 3.7,
`Queue(async=False)` has been changed to `Queue(is_async=False)`. The `async`
keyword argument will still work, but raises a `DeprecationWarning`. Thanks @dchevell!
### 0.11.0 (2018-06-01)

- `Job.create` now accepts `timeout` in string format (e.g `1h`). Thanks @theodesp!
- `worker.main_work_horse()` should exit with return code `0` even if job execution fails. Thanks @selwin!
- `job.delete(delete_dependents=True)` will delete job along with its dependents. Thanks @olingerc!
- Other minor fixes and documentation updates.
### 0.10.0

- RQ workers can now be paused and resumed using `rq suspend` and
`rq resume` commands. Thanks Jonathan Tushman!
- Jobs that are being performed are now stored in `StartedJobRegistry`
for monitoring purposes. This also prevents currently active jobs from
being orphaned/lost in the case of hard shutdowns.
- You can now monitor finished jobs by checking `FinishedJobRegistry`.
Thanks Nic Cope for helping!
- Jobs with unmet dependencies are now created with `deferred` as their
status. You can monitor deferred jobs by checking `DeferredJobRegistry`.

`queue.enqueue(func, at_front=True)`. Thanks Travis Johnson!

Useful for testing purposes. Thanks Cal Leeming!

### 0.4.4
(May 7th, 2014)
- Properly declare redis dependency.
- Fix a NameError regression that was introduced in 0.4.3.
### 0.4.3
(May 6th, 2014)
- Make job and queue classes overridable. Thanks, Marko!
- Don't require connection for @job decorator at definition time. Thanks, Sasha!
- Syntactic code cleanup.
### 0.4.2
(April 28th, 2014)

### 0.4.0
(April 22nd, 2014)
- Emptying the failed queue from the command line is now as simple as running
`rqinfo -X` or `rqinfo --empty-failed-queue`.

- Removed dependency on the `times` library. Thanks, Malthe!
- Job dependencies! Thanks, Selwin.
- Custom worker classes, via the `--worker-class=path.to.MyClass` command line
argument. Thanks, Selwin.

Thanks, Rob!
- Birth and death dates are now stored as proper datetimes, not timestamps.
- Ability to provide a custom job description (instead of using the default
function invocation hint). Thanks, İbrahim.

### 0.3.13

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)

### 0.3.10

- 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.
### 0.3.7
(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](http://python-rq.org/docs/jobs/).
- Custom properties can be set by modifying the `job.meta` dict. Relevant
documentation [here](http://python-rq.org/docs/jobs/).
- Custom properties can be set by modifying the `job.meta` dict. Relevant
documentation [here](http://python-rq.org/docs/jobs/).
- `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](http://python-rq.org/docs/exceptions/) and
[here](http://python-rq.org/patterns/sentry/).
- `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:secret@example.com/1"`
Alternatively, you can use a settings file and configure `SENTRY_DSN
= 'http://public:secret@example.com/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
(May 14, 2012)
- Thread-safety by using context locals
- Register scripts as console_scripts, for better portability
- Various bugfixes.
### 0.1.0:
(March 28, 2012)
- Initially released version.
