Vincent Driessen 240d2d941d Extracted method. 
This makes the act of moving failed jobs to the failed queue
responsibility of the FailedQueue itself, not of the Worker.

This fixes #32.
 13 years ago
Vincent Driessen d64ad225eb Make FailedQueue a full subclass of Queue. 
We will add special methods on it in the future.

This fixes #33.

Vincent Driessen 11c7dbb376 Consistently renamed "failure" -> "failed" queue. 
Fixes #28.

Vincent Driessen e05acfedce Fix putting jobs on the failure queue when they fail. 13 years ago
Vincent Driessen bffe6cbbde Encapsulate internal function call representation. 
This means it's not allowed anymore to directly set func, args, and
kwargs.  Instead, use the for_call() constructor.

Vincent Driessen 370399f8f7 CHECKPOINT: dequeue_any now returns the queue that was popped from. 13 years ago
Vincent Driessen f516f8df2e CHECKPOINT: Handle failing and unreadable jobs. 
Failing (or unreadable) jobs are correctly put on the failure queue by
the worker now.
 13 years ago
Vincent Driessen b1650cb9b9 CHECKPOINT: Second part of the big refactoring. 
Jobs are now stored in separate keys, and only job IDs are put on Redis
queues.  Much of the code has been hit by this change, but it is for the
good.

No really.

Vincent Driessen 1cbf92c166 Workaround for os.waitpid() throwing an OSError on SIGINT. 
When SIGINT (``Ctrl+C``) is received when inside a blocking
os.waitpid(), OSError is thrown, effectively cancelling the wait.

However, to facilitate a "warm shutdown", as we intend, Ctrl+C is
perfectly allowed and we want to keep waiting for the child.  Therefore,
we perform a trick here, catching OSError, checking whether its cause
was SIGINT (errno == EINTR), and only in that case, loop to os.waitpid()
again.

Vincent Driessen e278bd2967 Exit gracefully when user hits Ctrl+C in a worker. 
The currently running task will be waited for, so it can gracefully
be finished.  Further execution will be stopped.

If, during this waiting phase, Ctrl+C is hit again, the worker and the
horse will be terminated forcefully (this means work could be lost or
partially finished).

Vincent Driessen a5ea45af57 Make the dequeue methods return values consistent. 
I merely refactored the internal calls. No external API changes have been made in this commit. In order to make the dequeueing methods consistent, each dequeue method now returns a Job instance, which is just a nice lightweight wrapper around the job tuple.

The Job class makes it easier to pass the method call info around, along with some possible meta information, like the queue the job originated from.

This fixes #7.

Vincent Driessen f492a5ae2b Restructure some code. 
No functional change, but leave the BLPOP'ing to the Queue, as the
queues know how to pop themselves.
 14 years ago
Vincent Driessen 1a893e60cf Have work() return whether work has been done, or not. 
And promote Worker to the rq namespace, so you can
    from rq import Worker
 14 years ago
Vincent Driessen 1c9fa66bc1 Greatly simplify the setup. 
Jobs don't even need to be tagged.  Any function can be put on queues.

Vincent Driessen 8dfdd452ef Bugfix. 
Yeah, it's getting late.

It's my own fault.

I know.
 14 years ago
Vincent Driessen 04c88577ed Bugfix: LPOP does not support multiple queue arguments. 
Redis' BLPOP command takes multiple queue arguments, but LPOP can only
take a single queue.  Therefore, we need to loop over all queues
manually, in order, and raise an exception is no more work is available.
