* Add MutexPool for recorder tests
* Fix get_schema_version
* Update test test_last_run_was_recently_clean
* Update test test_shutdown_before_startup_finishes
* Revert comments in test_write_lock_db
* Make the MutexPool lock a class variable
* Remove stale comment
* Move MutexPool
* Tweak debug prints
* Avoid locking the database for non-SQLite backends
Currently we only have a lock implementation for SQLite. Just return
success for all other databases as they are not expected to store data
in the config directory and the caller can assume that a backup can
be safely taken.
This fixes `RuntimeError: generator didn't yield` errors when creating
a backup with the current Supervisor dev builds.
* Allow to set CONF_DB_URL
This is useful for test which need a custom DB path.
* Introduce write_lock_db helper to lock SQLite database
* Introduce Websocket API which allows to lock database during backup
* Fix isort
* Avoid mutable default arguments
* Address pylint issues
* Avoid holding executor thread
* Set unlock event in case timeout occures
This makes sure the database is left unlocked even in case of a race
condition.
* Add more unit tests
* Address new pylint errors
* Lower timeout to speedup tests
* Introduce queue overflow test
* Unlock database if necessary
This makes sure that the test runs through in case locking actually
succeeds (and the test fails).
* Make DB_LOCK_TIMEOUT a global
There is no good reason for this to be an argument. The recorder needs
to pick a sensible value.
* Add Websocket Timeout test
* Test lock_database() return
* Update homeassistant/components/recorder/__init__.py
