Vincent Driessen 4d2f64d4b6 Mental note to self. 14 years ago
Vincent Driessen 20e908039f Initially set the exc_info property, so it does not raise an 
AttributeException when accessed.

Vincent Driessen 7eb8d92605 Put unreadable tasks on the failure queue. 14 years ago
Vincent Driessen 0be1cb6ac0 Change the way jobs are pickled. 
There is no job tuple anymore, but instead Jobs are picklable by
themselves natively.  Furthermore, I've added a way to annotate Jobs
with created_at and enqueued_at timestamps, to drive any future Job
performance stats.  (And to enable requeueing, while keeping hold of the
queue that the Job originated from.)

This fixes #17.

Vincent Driessen 0503eb2829 Clarified responsibility of the Job class. 
The Job itself has nothing to do with queueing and dequeueing, so the
DequeueError wasn't appropriate here, either.

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 d780c929c0 Change semantics of work(). Add work_burst().

the burst-then-quit behaviour.

Vincent Driessen a491ff248d Add simple helper function, to avoid users to learn about the `conn`

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.
 14 years ago
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

Vincent Driessen 1c9fa66bc1 Greatly simplify the setup. 
Jobs don't even need to be tagged.  Any function can be put on queues.

Vincent Driessen 196a9815d2 Add dequeue method to Queue. 14 years ago
Vincent Driessen b5e0377eb0 Allow jobs to be declared without a default queue.

use enqueue().

Vincent Driessen 1b8da4a861 Add test for putting work on queues. 14 years ago
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.

Vincent Driessen a77c3d9104 Support quitting when all work is done (i.e. queue is empty). 14 years ago
