This bit of code was throwing exceptions if a test cleaned up files that
test-runner was expecting to clean up. Specifically testHotspot swaps out
main.conf and PSK files many times. This led to the exception being thrown,
caught, and ignored but further on test-runner would print:
"File _X_ not cleaned up!"
Now the files will be checked if they exist before trying to remove it.
Similarly to ofono/phonesim allow tests to be skipped if wpa_supplicant
is not found on the system.
This required some changes to DPP/P2P where Wpas() should be called first
since this can now throw a SkipTest exception.
The Wpas class was also made to allow __del__ to be called without
throwing additional exceptions in case wpa_supplicant was not found.
Many processes are not long running (e.g. hostapd_cli, ip, iw, etc)
and the separators written to log files don't show up for these which
makes debugging difficult. This is even true for IWD/Hostapd for tests
with start_iwd=0.
After writing separators for long running processes write them out for
any additional log files too.
Way too many classes have a dependency on the TestContext class, in
most cases only for is_verbose. This patch removes the dependency from
Process and Namespace classes.
For Process, the test arguments can be parsed in the class itself which
will allow for this class to be completely isolated into its own file.
The Namespace class was already relatively isolated. Both were moved
into utils.py which makes 'run-tests' quite a bit nicer to look at and
more fitting to its name.
With how fast UML is hostapd events were being sent out prior to
ever calling wait_for_event. Instead set an IO watch on the control
socket and cache all events as they come. Then, when wait_for_event
is called, it can reference this list. If the event is found any
older events are purged from the list.
The AP-ENABLED event needed a special case because hostapd gets
started before the IO watch can be registered. To fix this an
enabled property was added which queries the state directly. This
is checked first, and if not enabled wait_for_event continues normally.
This allows the callers condition to be checked immediately without
the mainloop running. In addition may_block=True allows the mainloop
to poll/sleep rather than immediately return back to the caller. This
handles async IO much better than may_block=False, at least for our
use-case.
Namespace process logs were appearing under 'ip' (and also overwriting
actual 'ip' logs) since they were executed with 'ip netns exec <namespace>'.
Instead special case this and append '-<namespace>' to the log file name.
In addition processes executed prior to any tests were being put under
a folder (name of testhome directory). Now this case is detected and these
logs are put at the top level log directory.
In order to keep all test-runner dev scripts working and to work with
the new runner.py system some file renaming was required.
test-runner was renamed to run-tests
A new test-runner was added which only creates the Runner() class.
