The variable contains the server version and allows to determine
available features. This is relevant for API changes like HSET mappings
in version 4.0.0 or LPOS in version 6.0.6.
To keep the number of connection.info() calls low, the information is
*cached* once determined, as a server version unlikely changes while
keeping the connection up.

* Rename `dependent_jobs` to `jobs_to_enqueue` in queue.py
* Rename `dependencies_job_ids` to `dependency_ids`.
* Remove `as_text` (no more python2 support). Use `bytes.decode`
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.
When a job with dependents is _successful_ it's dependents are enqueued. Only if the FINISHing job's `result_ttl` is non-zero is the change in status persisted in Redis - that is, when each dependent job is enqueued, the _FINISHing_ job (,triggering the enqueueing,) has an _outdated_ status in redis. This avoids redundant call because if `result_ttl=0` then the job is deleted then deleted in `Job#cleanup`.
In order to enqueue the dependents, we therefore _exclude_ the FINISHing job from the check if each dependents' dependencies have been met.
* Add job status setting in enqueue_at (and in enqueue_in) methods

* WIP on scheduler's threading mechanism
* Fixed test errors
* Changed scheduler.acquire_locks() to instance method
* Added scheduler.prepare_registries()
* Somewhat working implementation of RQ scheduler
* Only call stop_scheduler if there's a scheduler present
* Use OSError rather than ProcessLookupError for PyPy compatibility
* Added `auto_start` argument to scheduler.acquire_locks()
* Make RQScheduler play better with timezone
* Fixed test error
* Added --with-scheduler flag to rq worker CLI

* Multi Dependency Support - Registration & Enqueue Call
Internal API changes to support multiple dependencies.
* Store all of a job's _dependencies_ in a redis set. Delete that set when a job is deleted.
* Add Job#fetch_dependencies method - which return all jobs a job is dependent upon and optionally _WATCHES_ all dependency ids.
* Use Job#fetch_dependencies in Queue#call_enqueue. `fetch_dependencies` now sets WATCH and raises InvalidJobDependency, rather than call_enqueue.
`Queue` and `Job` public APIs still expect single ids of jobs for `depends_on` but internally register them in a way that could support multiple jobs being passed as dependencies.
Next up: need to update Queue#enqueue_dependents
* Use existing fetch_many method to get dependencies.
Modify fetch_dependencies to use fetch_many.
* Remove default value for fetch_many's connection parameter
* PR review housekeeping
* Remove a duplicate test
* Oneline something
* Fix missing colon in dependencies key
* Delete job key, dependents and dependencies at once
* More Fixes From Code Review
Updates to Job, Queue and associated tests.
* When Checking dependencies Avoid, trip to Redis
* When checking the status of a job, we have a 'clean' status of all dependencies(returned from Job#fetch_dependencies) and the job keys are WATCHed, so there's no reason to go back to Redis to get the status _again_.
* Looks as though, the `_status` set in `Job#restore` was bytes while it was converted to text(`as_text`) in `Job#get_status` - for consistency(and tests) converting to text in `restore` as well.
* In `Queue#enqueue_call`, moved WATCH of dependencies_key to before fetching dependencies. This doesn't really matter but seems more _correct_ - one can imagine some rogue API adding a dependency after they've been fetched but before they've been WATCHEed.
* Update Job#get_status to get _local_ status
* If refresh=False is passed, don't get status from Redis; return the value of _status. This is to avoid a trip to Redis if the caller can guarantee that the value of `_status` is _clean_.
* More Fixups
* Expire dependency keys in Job#cleanup
* Consistency in Job#fetch_dependencies
* Convert `_dependency_id` to `_dependency_ids`
Change `Job`s tracking from a single id of it's dependencies from a single _id_ to a list of _id_s. This change should be private to `Job` - especially leaving `Job#to_dict` and `Job#restore`s treatment of a single 'dependency_id' intact.
This change modifies existing tests.
* Remove reliance upon dependency property in tests
... use dependency.id not `_dependency_id`
* Re-add assertions for Falsey Values
* Add _dependency_id property
For backwards compatibility with other libs such as django-rq and rq-scheduler

* modify zadd calls for redis-py 3.0
redis-py 3.0 changes the zadd interface that accepts a single
mapping argument that is expected to be a dict.
https://github.com/andymccurdy/redis-py#mset-msetnx-and-zadd
* change FailedQueue.push_job_id to always push a str
redis-py 3.0 does not attempt to cast values to str and is left
to the user.
* remove Redis connection patching
Since in redis-py 3.0, Redis == StrictRedis class, we no longer
need to patch _zadd and other methods.
Ref: https://github.com/rq/rq/pull/1016#issuecomment-441010847
* Define redis key prefix as class variable
Some prefixes were hardcoded in several places. This made it hard to
use custom prefixes via subclasses.
Resolves#920
* fixup! Define redis key prefix as class variable
* Initial take on delete_dependents
* Add tests including corner cases
* No need to canel dependents since they are not in a queue yet anyway
* The dependents keys can be deleted in all cases
* Update tests to included saved jobs in the deletion tests
* Correctly use pipeline in cancel method
* Unused connection
* Include dependents into dict format of job
* Add TODO
* Address comments from selwin
* Delete dependents key in redis if delete_dependents is called on its own
* Address recent comments from selwin
* Small change to trigger travis
* Remove TODO referring to canceled job state
* Remove dependent_ids from to_dict
* Address recent comments from selwin
This includes:
- a partial refactor of the CLI to organize the shared options
- extends the tests in areas where passing custom backend classes makes sense
- allow setting the core CLI options as env vars
- minor cosmetic changes here and there
