* Remove async_remove_listener
This avoids the ambuigity as to what happens if same callback is added multiple times.
* Keep track of a context for each listener
This allow a update coordinator to adapt what data to request on update from the backing service based on which entities are enabled.
* Clone list before calling callbacks
The callbacks can end up unregistering and modifying the dict while iterating.
* Only yield actual values
* Add a test for update context
* Factor out iteration of _listeners to helper
* Verify context is passed to coordinator
* Switch to Any as type instead of object
* Remove function which use was dropped earliers
The use was removed in 8bee25c938
* 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.
