resizefs: Fix regression when system booted with root=PARTUUID=
A recent cleanup of the resizefs module broke resizing when a system was
booted with root=PARTUUID=<uuid> and the device /dev/root does not exist.
This path is exposed with the Ubuntu 16.04 but not with Ubuntu 17.10. A
recreate exists under bug 1684869.
tools: make yum package installation more reliable
During continuous integration tests, we're seeing quite a lot of
unreliablity when running 'yum install'. The change here is to move to
re-trying a run of 'yum install --downloadonly' for 10 times or until
it succeeds. Then afterwards, running yum install from the cache.
This seems safer in general than just re-trying an install operation,
since we are specifically affected by the download phase failing.
Also present are some flake8 fixes to tools/read-dependencies.
citest: fix remaining warnings raised by integration tests.
There was fallout in a full integration test run from my adding of
test_no_warnings_in_log which asserted that there could not be a WARNING
found in the /var/log/cloud-init.log
This fixes 2 of the cases:
* TestCommandOutputSimple had a valid WARNING written, so adjust its
test case to allow for that.
* TestLxdDir had a valid config in the test but the module would
log a WARNING, so fix the module.
Also updates lxd unit tests to look for WARN themselves.
citest: show the class actual class name in results.
Tests are currently run by creating a temporary subclass of each class
and then executing it (in get_suites). When running the tests suite
the output would contain the temporary class name. That was less than
useful, and made batch runs almost impossible to identify which
test case had an error.
This change goes from output of:
FAIL: test_no_warnings_in_log \ (tests.cloud_tests.testcases.get_suite.<locals>.tmp)
To
FAIL: test_no_warnings_in_log \ (tests.cloud_tests.testcases.modules.ntp.TestNtp)
