In #1496, we observed a situation where the `work()` method crashes after
`.subscribe()`, but prior to the `try/except` block which normally cleans up
after `.subscribe()`.
Specifically, `.subscribe()` launches a thread in non-daemon mode. Because of
that setting, Python will keep the calling worker process active, even if the
main thread has crashed. This resulted in a syndrome where a worker process was
running, but doing no work.
The change launches this thread in daemon mode, i.e. prevents a "zombie" pubsub
thread from keeping the process up.
(An additional change we could make, discussed in #1496 but deferred, would be
to improve the error handling/trapping scope in `.work()` such that all
failures trigger resource cleanup.)
* job: add get_meta() function
The newly introduced function returns meta data stored for the job. This
is required since job.meta stays an empty dict until the job is
finished or failed.
With the new function it's possible to store arbiatraty states/stages of
the job and allow the user to track progress. A long running job may
return custom stages like `downloading_data`, `unpacking_data`,
`processing_data`, etc.
This may allow better interfaces since users can track progress.

This was previously missing.

* Fix section header
* Fix section header again
* Update rq version to 1.9.0
* adds unit test for a deserialization error
This tests that deserialization exceptions are properly logged, and fails in
the manner described in #1422 .
* Catch deserializing errors in Worker.handle_exception()
This fixes#1422 , and makes
tests/test_worker.py::TestWorker::test_deserializing_failure_is_handled
pass.
* made unit test less specific
This is required to get the test to pass under other serializers / other
python versions.
* Added generic DeserializationError
* switched ValueError to DeserializationError in a test
The changed test is creating an invalid job, which now raises
DeserializationError when data is accessed, as opposed to ValueError.
* Removed deprecated (object) inheritance
Add new py38,py39 versions to tox, removed deprecated py27,py34
Replace enum internal function with Enum class
* fix
* cleanup jobs that are not really running due to zombie workers
* remove registry entries for zombie jobs
* return only the job ids on cleanup
* test zombie job cleanup
* format code
* rename variable to explain that second element in tuple is expiry, not score
* remove worker_key
* detect zombie jobs using old heartbeats
* reuse get_expired_job_ids
* set score using current_timestamp
* test idle jobs using stale heartbeats
* extract timeout into variable
* move heartbeats into StartedJobRegistry
* use registry.heartbeat in tests
* remove heartbeats when job removed from StartedJobRegistry
* remove idle and expired jobs from both wip and heartbeats set
* send heartbeat_ttl to registry.add
* typo
* revert everything 😶
* only keep job heartbeats as score (and get rid of job timeouts as scores
* 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

* 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.
If a UNIX socket path is passed to the constructor of the Redis client,
`redis.client.Redis`, the value of keyword argument `unix_socket_path`
is passed to the constructor of `UnixDomainSocketConnection` with the
key `path`.
When RQ's scheduler creates its own Redis connection, it instantiates
class `redis.client.Redis` with keyword arguments obtained from the
connection pool. If the pooled connection is a
`UnixDomainSocketConnection`, its keyword arguments contain `path`, as
given on instantiation. This results in a `TypeError: __init__() got an
unexpected keyword argument 'path'`.
This change renames the key back to `unix_socket_path` before the
keyword arguments dictionary is used to instantiate
`redis.client.Redis`.
* 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
