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. 14 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.
 14 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 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 fdce187c27 Putting failed jobs on the failure queue. 14 years ago
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.
 14 years ago
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.
 14 years ago
Vincent Driessen db5753b0d6 Put Job in its own file. 14 years ago
Vincent Driessen 210477c2ab Throw DequeueError when reading unprocessable data from queue. 14 years ago
Vincent Driessen 62ae299114 Fix mathematical meaning of the < operator. 
This is used for alphabetical queue ordering.

This ain't the right way to terminate when blocking by pop.

Vincent Driessen 7769d9875f Perform a warm shutdown on SIGTERM, too. 
Just like with Ctrl+C (SIGINT), shutdown warmly at first when kill'ed
(SIGTERM).

Vincent Driessen 88cbaa1df9 Slight code reshuffle + added some comments on the construction. 14 years ago
Vincent Driessen 7cba8449d9 Add comments. 14 years ago
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).
