clean: correctly determine the path for excluding seed directory
Previously, init.paths.cloud_dir has a trailing slash, which meant that
"/var/lib/cloud//seed" was being compared to "/var/lib/cloud/seed" and
(of course), never matching.
In this commit, switch to using os.path.join to avoid this case (and
update the tests to catch it in future).
helpers/openstack: Treat unknown link types as physical
Some deployments of OpenStack expose link types to the guest which
cloud-init doesn't recognise. These will almost always be physical, so
we can operate more robustly if we assume that they are (whilst warning
the user that we're seeing something unexpected).
pylint now complains about assignment of None from a
return of a function call. This does not account for subclassing
so we resolve this issue by removing the assignment in the unittest.
net: append type:dhcp[46] only if dhcp[46] is True in v2 netconfig
When providing netplan configuration to cloud-init, the internal
network state would enable DHCP if the 'dhcp' key was present in
the source config. In netplan, dhcp[46] is a boolean and the
value of the boolean should control whether DHCP is enabled rather
than the presence of the key. This issue leaded to inconsistant
sysconfig/network-scripts on fedora. 'BOOTPROTO' was always 'dhcp',
even if the address config was static.
After this change a dhcp subnet is added only if the 'dhcp' setting
in source cfg dict is True.
cc_apt_pipelining: stop disabling pipelining by default
This was introduced due to Ubuntu using S3 mirrors, and S3 having a
buggy pipelining implementation. Those Ubuntu mirrors are no longer in
production and, furthremore, apt has also grown the ability to handle
servers with broken pipelining.
As such, we can stop disabling pipelining, which should result in
improved apt download speeds.
In test_ds_identify, don't mutate otherwise-static test data. When
running tests in a random order, this was causing failures due to
breaking preconditions for other tests.
In tests/helpers, reset logging level in tearDown. Some of the CLI
tests set the level of the root logger in a way that isn't correctly
reset.
For test_poll_imds_re_dhcp_on_timeout and
test_dhcp_discovery_run_in_sandbox_warns_invalid_pid, mock out
time.sleep; this saves ~11 seconds (or ~40% of previous test time!).
