Commit 287a0b4 introduced a segfault when validating the i3 config
as the root_screen will not be set in this case, causing a null
pointer dereference.

complete-run.pl - Run the i3 testsuite
|
||
|
||
=head1 SYNOPSIS
|
||
|
||
complete-run.pl [files...]
|
||
|
||
=head1 EXAMPLE
|
||
|
||
To run the whole testsuite on a reasonable number of Xephyr instances (your
|
||
running X11 will not be touched), run:
|
||
./complete-run.pl
|
||
|
||
To run only a specific test (useful when developing a new feature), run:
|
||
./complete-run t/100-fullscreen.t
|
||
|
||
=head1 OPTIONS
|
||
|
||
=over 8
|
||
|
||
=item B<--display>
|
||
|
||
Specifies which X11 display should be used. Can be specified multiple times and
|
||
will parallelize the tests:
|
||
|
||
# Run tests on the second X server
|
||
./complete-run.pl -d :1
|
||
|
||
# Run four tests in parallel on some Xephyr servers
|
||
./complete-run.pl -d :1,:2,:3,:4
|
||
|
||
Note that it is not necessary to specify this anymore. If omitted,
|
||
complete-run.pl will start (num_cores * 2) Xephyr instances.
|
||
|
||
=item B<--valgrind>
|
||
|
||
Runs i3 under valgrind to find memory problems. The output will be available in
|
||
C<latest/valgrind-for-$test.log>.
|
||
|
||
=item B<--strace>
|
||
|
||
Runs i3 under strace to trace system calls. The output will be available in
|
||
C<latest/strace-for-$test.log>.
|
||
|
||
=item B<--xtrace>
|
||
|
||
Runs i3 under xtrace to trace X11 requests/replies. The output will be
|
||
available in C<latest/xtrace-for-$test.log>.
|
||
|
||
=item B<--coverage-testing>
|
||
|
||
Generates a test coverage report at C<latest/i3-coverage>. Exits i3 cleanly
|
||
during tests (instead of kill -9) to make coverage testing work properly.
|
||
|
||
=item B<--parallel>
|
||
|
||
Number of Xephyr instances to start (if you don't want to start num_cores * 2
|
||
instances for some reason).
|
||
|
||
# Run all tests on a single Xephyr instance
|
