Fix how the comparison of a fqdn and its aliases was done
via sorting instead of existence checking which is the better
way to check if a alias already exists as well as cleanup
the new files pep8/pylint issues.

helper objects.
1. Add in a parser for the /etc/hostname file that can be shared
2. Adjust the sysconfig configobj parser to not always quote
fields that it does not need to quote + add in tests around
this to ensure that we don't go nuts with quoting again.

of this function that needs to occur since
its pretty much the same now.

1. Move out the old helpers that provided oop access/reading/writing
to various standard conf files and place those in parsers instead.
2. Unify the 'update_hostname' which varied very little between distros
and make it generic so that subclasses can only provide a couple of
functions to obtain the hostname updating functionality
3. Implement that new set of functions in rhel/debian
4. Use the new parsers chop_comment function for similar use
cases as well as add a new utils make header function that
can be used for configuration files that are newly generated
to use (less duplication here of this same thing being done
in multiple places.
5. Add in a distro '_apply_hostname' which calls out to the 'hostname'
program to set the system hostname (more duplication elimination).
6. Make the 'constant' filenames being written to for configuration
by the various distros be instance members instead of string
constants 'sprinkled' throughout the code

to ensure that even if they are found that they
are also valid, before they are assumed to be
the correct device name.
|

Also fix the extraction of the metadata key name
since it actually uses 'dashes' instead of being
a single word.
|
|
translate the device name to a actual device using
logic that will try the ec2 metadata (if avail) or
will try using 'blkid' to find a corresponding label.

we map 'hostname' to 'local-hostname'
so that the modules work correctly with
the cfgdrive style of data.

This fixes (tested) bug 978127. The server was actually returning a 401
not a 403. As such, the fix here was insufficient. This will now take
either of those 2 error codes. I've also tested it by changing the clock
in the cloud-init upstart job with a stanza like below, and verifying
that we do see the problem and then it resolve itself:
pre-start script
offset="10 minutes ago"
past=$(date -R --date "$offset")
date --set "$past" &&
echo ===== "set date to $past [$offset]" ===== ||
echo ===== "failed to set date to $past [$offset]" ====
end script

Rework the rest of the locations that used the previous 'user' and make
those locations go through the new distros functions to select the default
user or the user list (depending on usage).
Adjust the tests to check the new 'default' field that signifies the
default user + test the new method to extract just the default user from a
normalized user dictionary.
"default" user is now marked in the user dict and get_default_user uses
that.

In 0.7.0 we started using yaml.safe_load to load data rather than
yaml.load. Some producers (namely, ubuntu MAAS created) have produced
cloud-config data in the past that included python unicode types.
This creates a specialized safe_loader that is basically safe_load +
support for python unicode.

Packages on debian/ubuntu should start on installation. As a result, if we
want to get config changes we've inserted to be read, we need to restart.
Note one interesting thing here.
upstart considers 'restart' as "restart only if currently running", while
'service' considers restart to be "stop if running, then start". So the use of
'service' here is important, rather than just 'restart'

The primary utility here is normalize_user_groups, which would
be called by config modules to get a list of users or groups.
This centralizes what was copied code into this one location.

and produce a user and group list. Clean this up to
be simpler as well as handle the old 'user' case when
it exists in configuration.

Rework the rhel sysconfig writing/updating so that it goes through a
single function which helps ensure correctness. Also write to
/etc/sysconfig/network when we have written out devices to ensure that
networking is on.
|

|

|

|
Fix the ifup so that if a list of devices is provided then each interface is
brought up individually instead of using the '--all' which isn't on rhel.
The default debian behavior will be to use this still though as it overrides
the new bring up interfaces function for this case.

In the event of a 403 (Unauthorized) in oauth, try set a 'oauth_clockskew'
variable. In future headers, use a time created by 'time.time() +
self.oauth_clockskew'. The idea here is that if the local time is bad (or even
if the server time is bad) we will essentially use something that should be
similar to the remote clock.
This fixes LP: #978127.

since it has little dependence on the distros
class itself. Readjust the using code to use
