If the test case couldn't connect to the VM with SSH, it used to fail
with a Python error of accessing the 'missing' variable without having
it defined.
With this commit, it prints out 'Could not connect to the VM via SSH'
instead.
We have a test case, that performs full installations with with XFCE4
and Plasma Mobile. After each installation is through, we run
"pmbootstrap qemu" and connect to the VM via SSH to check for specific
running processes.
Before this commit, we assumed that the boot takes 90 seconds at most
and then the processes should exist. But sometimes the boot is faster
(so Travis waits just doing nothing) and sometimes it is slower (which
causes the test case to fail), all depending on the current workload
of the Travis CI servers. Now we try to find the processes we're
interested in each second for 3 minutes until we either succeed or
reach the time limit.
* Testsuite: Run UIs in Qemu and check running processes (and other changes)
* When `pmbootstrap qemu` gets killed, it now takes down the Qemu process with it
* `test/check_checksums.py` got a new optional `--build` parameter, which makes
it build all changed packages instead of just checking the checksums
* We run this before running the testsuite now, so all changed packages get
built before running tests (otherwise tests would hang without any output
while a changed package is building)
* New testcase, that zaps all chroots, installs a specific UI (xfce4 and
plasma-mobile currently, easy to extend), runs it via Qemu and checks the
running processes via SSH.
* Version checking testcase: rewritten to include Alpine's testsuite file in
our source tree, so we don't need to clone their git repo anymore. Now it
is enabled for Travis.
* All this gives us a nice 10% code coverage boost
* Increased the `hello-world` pkgrel to verify that the Travis job is working.
* Various fixes
* Build device-packages for the device arch and don't raise an
exception, but print a note if --ignore-depends is not specified
and therefore the kernel gets installed, too.
* Don't use --force when building in Travis (because abuild doesn't
check the checksums then. Bug report on the way.)
* Don't run the building process in the background, but wait for its
completion
* Exit with 1 when showing usage in check_checksums.py
