* calculate heartbeat_ttl in an overrideable function + override it in SimpleWorker + move storing StartedJobRegistry scores to job.heartbeat()
* set heartbeat to monitoring interval for infinite timeouts
* track elapsed_execution_time as part of worker
* reset current job working time when work on a job is done
* persisting the job working time as part of monitoring
* implemented round-robin and random access to queues
* added tests for RoundRobinQueue
* reverted change in gitignore
* removed linebreak
* added tests for random queues
* added documentation for round robin and random queues
* moved round robin strategy to worker
* reverted changes to queue.py
* reverted changes to workers.md
* reverted changes to test_queue
* added tests for RoundRobinWorker and RandomWorker
* added doc for round robin and random workers
* removed f-strings for backward compatibility
* corrected a mistake
* minor changes (code style)
* now using _ordered_queues instead of queues for reordering queues
* Also accept lists and tuples as value of `depends_on`.
* The elements of the lists/tuples may be either Jobs or Job IDs.
* A single Job / Job ID is still accepted as well.
* Represent _all_ job dependencies in `Job.to_dict()`.
We now represent the entire list, instead of just the first element.
* Fix some doctext regarding plurality of dependencies.
* Add unit tests for job dependencies.
* One unit test establishes a pattern for checking execution order as affected by dependencies.
* Another unit test applies this pattern to the new capability to name multiple dependencies.
* Add unit test for new `depends_on` input formats.
Also test that these are properly persisted.
* Repair `Job.restore()`.
Need to convert bytes back to strings when reloading `dependency_ids`.
* Maintain backwards compat. in `Job.to_dict()`.
Keep the old `dependency_id` (singular) key.
* Provide coverage for new test fixture.
* Simplify some code.
Cut some superfluous `as_text()` calls left over from an earlier commit.
* Check for `dependency_id` in `Job.restore()` for backwd. compat.
Also eliminate use of `as_text()` here, in favor of `.decode()`.
* Switch to snake case instead of camel case.
* Eliminate some usages of `as_text()`.
Also cut some `print` statements.
* Cleanup.
* Accept arbitrary iterables for `Job`'s `depends_on` kwarg.
Instead of requiring a list or tuple, we now make use of `ensure_list()`.
* Add test fixtures.
* Provide a system to get two workers working simultaneously, using `multiprocessing`.
* Define a simple job that just says whether its dependencies are met.
* In `rpush`, make an option to record the name of the worker.
* Improve unit tests on execution order with dependencies.
These now actually have two workers going, which makes a more thorough test.
* Add unit test examining `Job.dependencies_are_met()` at execution time.
* Redesign dependency execution order unit tests.
* Simplify assertions.
* Improve doctext and formatting.
* Move fixture tests to new, dedicated module `test_fixtures.py`.
* Use `enqueue` instead of `enqueue_call` in new unit tests.
* clean_worker_registry cleans in batches to prevent submitting too much data to redis at once when there are a large number of invalid keys
* Address code review comments
Rename MAX_REMOVABLE_KEYS to MAX_KEYS
* Fix tests

* Ensure that the custom serializer defined is passed into the job fetch calls
* add serializer as argument to fetch_many and dequeue_any methods
* add worker test for custom serializer
* move json serializer to serializers.py
* Added send_stop_job_command().
* send_stop_job_command now accepts just connection and job_id
* Document send_job_job_command
* Updated test coverage
* feat: added job heartbeat to track whether job is actually executing
heartbeat might be needed in cases when worker was hardkilled or the whole VM/docker was forcibly rebooted.
* fixed tests
* fixed test coverage issue
* chore: renamed job.heartbeat stuff according to review feedback
* chore: pipelined worker heartbeat and job heartbeat
* docs: documented job.heartbeat property
* fixes after review
* docs: updated last_heartbeat description
* chore: review

* scheduler: now operates with chunks of jobs
* scheduler: set default chunk_size for ScheduledJobRegistry.get_jobs_to_schedule
* scheduler: fixed missing indent
* scheduler: added test for get_jobs_to_schedule() with chunk_size parameter
* scheduler: fixed test for passing python 3.5 (no f-strings)
* scheduler: fixed chunk_size in test make it lighter to run
* feat: avoided "zombie" processes after killing work horse by setting work horse process group and killing this group
* fixed tests
* tests: added test to check that all workhorse subprocesses are killed
* tests: updated guthub run tests dependencies since they are not using (dev-)requirements.txt

* handled unhandled exceptions in horse to prevent a job from being silently dropped without going into FailedRegistry
* changes after review
* made sure that work_horse always terminates in a proper way with tests
* minor refactoring
* fix for failing test
* fixes for the other tests
- removed exception handling (done in monitor_work_horse)
- adjusted some tests for the checks that are not relevant anymore
* review suggested changes
* cleanup

* Initial implementation of Retry class
* Fixes job.refresh() under Python 3.5
* Remove the use of text_type in job.py
* Retry can be scheduled
* monitor_work_horse() should call handle_job_failure() with queue argument.
* Flake8 fixes
* Added docs for job retries
* Took into account DST when computing localtime zones. This wasn't accounted for when using non-UTC datetimes with queue.enqueue_at()
* Updates tests with mocked timezones to test both scenarios
1) Check if `created_at` when checking if dependencies are met.
If `created_at` is `None` then the job has been deleted. This is sort of hack - we just need one of the fields on the job's hash that is ALWAYS populated. You can persist a job to redis without setting status...
2) Job#fetch_dependencies no longer raises NoSuchJob.
If one of a job's dependencies has been deleted from Redis, it is not returned from `fetch_dependencies` and no exception is raised.
Method Queue#enqueue_dependents checks the status of all dependencies of all dependents, and enqueues those dependents for which all dependencies are FINISHED.
The enqueue_dependents method WAS called from Worker#handle_job_success called BEFORE the status of the successful job was set in Redis, so enqueue_dependents explicitly excluded the _successful_ job from interrogation of dependency statuses as the it would never be true in the existing code path, but it was assumed that this would be final status after the current pipeline was executed.
This commit changes Worker#handle_job_success so that it persists the status of the successful job to Redis, everytime a job completes(not only if it has a ttl) and does so before enqueue_dependents is called. This allows for enqueue_dependents to be less reliant on the out of band state of the current _successful job being handled_.
* Add job status setting in enqueue_at (and in enqueue_in) methods
Update tests for this change
Closes: #1179
* Add status param to create_job func, rework enqueue_at status setting
