Since we use git ls-files to produce the list of all tests for -A, if
the source directory is owned by somebody other than root one might
get:
fatal: unsafe repository ('/home/balrog/repos/iwd' is owned by someone else)
To add an exception for this directory, call:
git config --global --add safe.directory /home/balrog/repos/iwd
Starting

Mark args.testhome as a safe directory on every run.
The kernel will not let us test some scenarios of communication between
two hwsim radios (e.g. STA and AP) if they're in the same net namespace.
For example, when connected, you can't add normal IPv4 subnet routes for
the same subnet on two different interfaces in one namespace (you'd
either get an EEXIST or you'd replace the other route), you can set
different metrics on the routes but that won't fix IP routing. For
testNetconfig the result is that communication works for DHCP before we
get the inital lease but renewals won't work because they're unicast.
Allow hostapd to run on a radio that has been moved to a different
namespace in hw.conf so we don't have to work around these issues.
The --start option was directly passed to the kernel init parameter,
preventing any environment setup from happening.
Intead always use 'run-tests' as the init process but detect --start
and execute that binary/script once inside the environment.
In UML if any process dies while test-runner is waiting for the DBus
service or some socket to be available it will block forever. This
is due to the way the non_block_wait works.
Its not optimal but it essentially polls over some input function
until the conditions are met. And, depending on the input function,
this can cause UML to hang since it never has a chance to go idle
and advance the time clock.
This can be fixed, at least for services/sockets, by sleeping in
the input function allowing time to pass. This will then allow
test-runner to bail out with an exception.
This patch adds a new wait_for_service function which handles this
automatically, and wait_for_socket was refactored to behave
similarly.
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.
