tests: fix salt_minion integration test on bionic and later
In ubuntu, the salt-minion package version 2017.7.4+dfsg1-1 or later
automatically moves any seed keys from /etc/salt/pki/minion/ to
/var/lib/salt/pki/minion/. Fix integration tests to collect
either files in either /etc/salt/pki/minion/ or
/var/lib/salt/pki/minion/.
tests: provide human-readable integration test summary when --verbose
Integration tests will now provide a brief summary for test failures
listed by platform and distribution. The failure summary will only consist
of failed test name and assert error message.
Drop the verbose dictionary of all integration test output because this
content is unreadable given the large number of integration test results
listed within this dictionary.
tests: skip chrony integration tests on lxd running artful or older
A fix for chrony support per LP: #1589780 is not expected in Artful or
older series. Skip the chrony suite of tests when running on a container
and ubuntu series represented is <= artful as errors are expected.
test: add optional --preserve-instance arg to integraiton tests
By default, integration tests destroy the test instances after each
test run. To aid debug and development of integration tests, support a
--preserve-instance argument which will leave the modified test instance
in a stopped state for further debug.
netplan: fix mtu if provided by network config for all rendered types
When network configuration for any interface defines maximum transmission
values (MTU) the netplan, eni and sysconfig renders will take into account
any device-level, or subnet-level mtu values.
When network configuration has conflicting device-level and ipv4 subnet
mtu values, the subnet-specific value is honored and a warning will be
logged about any ignored device-level setting.
This adds 'combine_capture' argument as was present in curtin's
subp. It is useful to get interleaved output of a command. I noticed
a need for it when looking at user_data_rhevm in DataSourceAltCloud.
That will run a subcommand, logging its stdout but swallowing its stderr.
Another thing to change to use this would be in udevadm_settle which
currently just returns the subp() call.
Also, add the docstring copied from curtin's subp.
The pylxd project has a setup.py which defines install dependencies.
Those sub-dependendencies include pbr and requests which in turn have
package version conflicts. Since tox doesn't order dependencies installed,
serially install pinned urllib3 at 1.22 which supports both pbr deps and
requests deps of pylxd.
util: add get_linux_distro function to replace platform.dist
Allow the user to set the distribution with --distro argument to setup.py.
Fall back is to read /etc/os-release. Final backup is to use
platform.dist() Python function. The platform.dist() function is
deprecated and will be removed in Python 3.7
pyflakes: fix unused variable references identified by pyflakes 2.0.0.
A newer version of pyflakes (2.0.0) was released.
It identifed some unused variables that version 1.6.0 did not identify.
The change here merely fixes those unused variables.
