Ubuntu 20.04 comes with Python 3.8 which doesn't have
`platform.freedesktop_os_release()`. This change catches the exception
if this happens, as well as other exceptions we might get so that the
initialization of Sentry will succeed.
Fixes#9773.
This change adds additional details to Sentry events so that the "All
Events" tab on keyman.sentry.io will show helpful values in the
"device" and "os" columns instead of emptry strings.
The `hash` method that we previously used calculates the hash based on
the memory location, i.e. with each program run we get a different value
for the same user. This change now uses the md5 algorithm so that the
same user always produces the same hash.
When running on Ubuntu 20.04 Focal, one of the Python dependencies
loads the `unittest` module so that running `km-config` output the
message that Sentry would be disabled because unit tests are running.
This change now uses the callstack to check if we're running unit
tests.
Fixes#9577.
We can't initialize Sentry during module initialization because our
`initialize_sentry` logs some status info. Setting the logging level
later on is then a no-op, breaking verbose and very-verbose logging.
This change fixes this by putting Sentry initialization into a
separate method that gets called after we set the log level.
Also refactor some common code into methods that appear in all our
executables.
