* Remove unnecessary exception re-wraps
* Preserve exception chains on re-raise
We slap "from cause" to almost all possible cases here. In some cases it
could conceivably be better to do "from None" if we really want to hide
the cause. However those should be in the minority, and "from cause"
should be an improvement over the corresponding raise without a "from"
in all cases anyway.
The only case where we raise from None here is in plex, where the
exception for an original invalid SSL cert is not the root cause for
failure to validate a newly fetched one.
Follow local convention on exception variable names if there is a
consistent one, otherwise `err` to match with majority of codebase.
* Fix mistaken re-wrap in homematicip_cloud/hap.py
Missed the difference between HmipConnectionError and
HmipcConnectionError.
* Do not hide original error on plex new cert validation error
Original is not the cause for the new one, but showing old in the
traceback is useful nevertheless.
* Add limit parameter to service call methods
* Break out prep part of async_call_from_config for use elsewhere
* Minor cleanup
* Fix improper use of asyncio.wait
* Fix state update
Call change listener immediately if its a callback
* Fix exception handling and logging
* Merge Script helper if_running/run_mode parameters into script_mode
- Remove background/blocking _ScriptRun subclasses which are no longer needed.
* Add queued script mode
* Disable timeout when making fully blocking script call
* Don't call change listener when restarting script
This makes restart mode behavior consistent with parallel & queue modes.
* Changes per review
- Call all script services (except script.turn_off) with no time limit.
- Fix handling of lock in _QueuedScriptRun and add comments to make it
clearer how this code works.
* Changes per review 2
- Move cancel shielding "up" from _ScriptRun.async_run to Script.async_run
(and apply to new style scripts only.) This makes sure Script class also
properly handles cancellation which it wasn't doing before.
- In _ScriptRun._async_call_service_step, instead of using script.turn_off
service, just cancel service call and let it handle the cancellation
accordingly.
* Fix bugs
- Add missing call to change listener in Script.async_run
in cancelled path.
- Cancel service task if ServiceRegistry.async_call cancelled.
* Revert last changes to ServiceRegistry.async_call
* Minor Script helper fixes & test improvements
- Don't log asyncio.CancelledError exceptions.
- Make change_listener a public attribute.
- Test overhaul
- Parametrize tests.
- Use common test functions.
- Mock timeout so tests don't need to wait for real time to elapse.
- Add common function for waiting for script action step.
* Add tests for legacy Script helper behavior
* Add Script helper if_running and run_mode options
- if_running controls what happens if Script run while previous run
has not completed. Can be:
- error: Raise an exception
- ignore: Return without doing anything (previous run continues as-is)
- parallel: Start run in new task
- restart: Stop previous run before starting new run
- run_mode controls when call to async_run will return. Can be:
- background: Returns immediately
- legacy: Implements previous behavior, which is to return when done,
or when suspended by delay or wait_template
- blocking: Returns when run has completed
- If neither is specified, default is run_mode=legacy (and if_running
is not used.) Otherwise, defaults are if_running=parallel and
run_mode=background. If run_mode is set to legacy then if_running must
be None.
- Caller may supply a logger which will be used throughout instead of
default module logger.
- Move Script running state into new helper classes, comprised of an
abstract base class and two concrete clases, one for legacy behavior
and one for new behavior.
- Remove some non-async methods, as well as call_from_config which has
only been used in tests.
- Adjust tests accordingly.
* Change per review
- Change run_mode default from background to blocking.
- Make sure change listener is called, even when there's an unexpected
exception.
- Make _ScriptRun.async_stop more graceful by using an asyncio.Event for
signaling instead of simply cancelling Task.
- Subclass _ScriptRun for background & blocking behavior.
Also:
- Fix timeouts in _ScriptRun by converting timedeltas to float seconds.
- General cleanup.
* Change per review 2
- Don't propagate exceptions if call from user has already returned
(i.e., for background runs or legacy runs that have suspended.)
- Allow user to specify if exceptions should be logged. They will still
be logged regardless if exception is not propagated.
- Rename _start_script_delay and _start_wait_template_delay for
clarity.
- Remove return value from Script.async_run.
- Fix missing await.
- Change call to self.is_running in Script.async_run to direct test of
self._runs.
* Change per review 3 and add tests
- Remove Script.set_logger().
- Enhance existing tests to check all run modes.
- Add tests for new features.
- Fix a few minor bugs found by tests.
* Type check all helpers, add inline exclusions for work in progress
* Remove unused Script._template_cache
* Add some missing type hints
* Remove unneeded type: ignore
* Type hint fixes
* Mypy assistance tweaks
* Don't look for None in deprecated config "at most once" check
* Avoid None name slugify attempt when generating entity id
* Avoid None state store attempt on entity remove
