2023-05-30py: unittests.py: Add weakref helpers and use delTomi Valkeinen
Add helpers to check if a weakref or a list of weakrefs is alive or dead. Also use 'del' for local variables instead of setting the variable to None. This makes debugging the test easier as the locals will be gone from locals() dict.

2023-05-30py: Use exceptions instead of returning error codesTomi Valkeinen
We have multiple methods which return an error code, mimicking the C++ API. Using exceptions is more natural in the Python API, so change all those methods to raise an Exception instead.

2023-05-30py: Fix CameraManager.version propertyTomi Valkeinen
The current CameraManager.version doesn't work at all (raises a TypeError), as that's not how you use expose C++ static methods as Python class methods. Fix it.

2022-08-19py: Switch to non-blocking eventfdTomi Valkeinen
Blocking wait can be easily implemented on top in Python, so rather than supporting only blocking reads, or supporting both non-blocking and blocking reads, let's support only non-blocking reads.

2022-06-04py: Merge read_event() and get_ready_requests()Tomi Valkeinen
We always call CameraManager.read_event() and CameraManager.get_ready_requests(), so to simplify the use merge the read_event() into the get_ready_requests(). This has the side effect that get_ready_requests() will now block if there is no event ready. If we ever need to call get_ready_requests() in a polling manner we will need a new function which behaves differently. However, afaics the only sensible way to manage the event loop is to use select/poll on the eventfd and then call get_ready_requests() once, which is the use case what the current merged function supports.

2022-06-01py: unittests: Fix test_select()Tomi Valkeinen
The test_select() currently uses self.assertTrue(len(ready_reqs) > 0) to see that cm.get_ready_requests() returns something. This is not always the case, as there may be two eventfd events queued, and the first call to cm.get_ready_requests() returns all the requests, and thus the second call returns none. Remove the self.assertTrue(len(ready_reqs) > 0) assert.

2022-06-01py: unittests: Fix test_sleep()Tomi Valkeinen
Waiting for 0.5 secs and expecting that the requests have been completed is... bad. Fix the test case by using cam.read_event() as a blocking wait, and wait until we have received all the requests that we queued.

2022-05-27py: Rename 'efd' to 'event_fd'Tomi Valkeinen
Perhaps it's better to have a more descriptive name here. I also considered just renaming 'efd' to 'fd', but 'event_fd' won.

2022-05-27py: Add CameraManager.read_event()Tomi Valkeinen
Add CameraManager.read_event() so that the user does not need to call os.read(). We use eventfd, and we must always read 8 bytes. Hiding that inside read_event() makes sense.

pyright complains about passing fileobj to os.read. Indeed, the parameter should be an int, but I guess fileobj gets automatically converted. In any case, using the fd is better.
