LD_LIBRARY_PATH is set earlier than some of the other environment
variables like PATH or PYTHONPATH, so trying to save a clean version in
snapcraft is not viable. Remove it here.
SingleInstanceTask has distinct steps for creation of the object, and
starting the task. If a different coroutine is waiting on the
SingleInstanceTask, it isn't safe to directly call
SingleInstanceTask.wait() as the task may or may not have been created
yet.
Existing code usage of SingleInstanceTask is in 4 categories, with
reguards to SingleInstanceTask.wait():
1) using SingleInstanceTask without using SingleInstanceTask.wait().
This is unchanged.
2) using SingleInstanceTask.wait without a check on task is not None.
This may be safe now, but is fragile in the face of innocent-looking
refactors around the SingleInstanceTask.
3) using SingleInstanceTask.wait after confirming that the task is not
None. This is fine but a leaky abstraction.
4) directly waiting on the SingleInstanceTask.task. Another leaky
abstraction, but it's solving a cancellation problem. Leaving this
alone.
By enhancing SingleInstanceTask.wait(), cases 2 and 3 are improved. The
code not checking the task today is made safer, and the code checking
the task today can be simplified.
parameterized async tests run into cpython bug gh-101486
We use parameterized.expand, which works by creating new functions and
inserting those into the list of tests. It's a wonder this worked at
all before for the async tests.
Update the function generation to create a coroutine function, if
appropriate.
LP: #2007554
BaseView.remove_overlay() would crash with AttributeError if no overlay
was found. We now add a not_found_ok parameter (defaulting to True) that
makes the function silently return if the overlay could not be found.
Passing not_found_ok=False and catching OverlayNotFoundError can be
helpful in some scenarios to do something different if no overlay was
found.

Tests that use run_coro are at risk of being broken by the introduction
of another test using IsolatedAsyncioTestCase. Switch over to only use
IsolatedAsyncioTestCase.
cancel_restart is a mode for SingleInstanceTask that changes the
behavior when starting the task - if the task is already running, do not
cancel it to start another.
So that we consistently return the same value from lsb_release() across
all calls that use dry-run, the function now accepts a dry_run argument
(defaulting to False). This way, in dry-run mode, the caller does not
need to supply the path to a specific example file anymore.
lsb_release(dry_run=True) -> will load examples/lsb-release-focal
Having said that, the caller is still left with the possibility to
specify the example file by using the path argument:
lsb_release(path="example/lsb-release-impish")
The path and dry_run arguments are mutually exclusive: providing both
will result in a ValueError.

Fix warning:
subiquitycore/tests/test_view.py:24
subiquity/subiquitycore/tests/test_view.py:24:
PytestCollectionWarning: cannot collect test class 'TestStretchy'
because it has a __init__ constructor
* TimeZone: autoinstall and API
Add support for Get/Set timezone methods. Get means that we inquire
with GeoIP as to which timezone is suggested. Non-availability of
GeoIP, or a previous explicit Set, means that we return the system
timezone. Set of timezone by Post results in set of the live system
timzeone, and queuing a set of the target system by way of cloud-init.
* Add clarifying comment about _request.
Move mock_app to common location.
Move run_coro to subiquitycore so that subiquitycore doesn't have to
reference things in subiquity, even for test.
Move task tracking things from mirror to geoip.
Server app owns the geoip instance.
Create EventCallback as an alternative to MessageHub that should
hopefully express clearer intermodule dependencies.
When user configures network with subiquity, it's rendered
netplan should be wholly definitive. So, we remove the other files
that may have config. This fixes a bug where running in an instance
when running on a system where cloud-init had rendered a 'match' with
'macaddress'.
When writing netplan we keep 'macaddress' match in place but drop
others. The others may just wildcard from the installer environment,
but macaddress are likely by cloud-init or otherwise intentionally
written.
Also add an atomic write in subiquitycore/file_util and move the
netplan code into subiquitycore/netplan.py, and add some unit test
helpers from cloud-init.
