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.

Under Python 3.7, we are seeing `FutureWarning: Possible nested set at
position 23`; escaping this bracket causes that warning to disappear.

Encrypted data bags require a secrets file to be present to
decrypt, and the location of the file must be configured the
Chef client configuration file, client.rb.
This update enables cloud-init's chef module to update that
setting in client.rb.

When using the LXD module cloud-init will attempt
to install ZFS if it does not exist on the target
system. However instead of installing the `zfsutils-linux`
package it attempts to install `zfs` resulting in an error.
Ubuntu Xenial (16.04) has zfs meta package, but Bionic (18.04)
does not. Use the specific base package instead of zfs meta.

Correct invalid regex to match hashes starting with the following:
- $1, $2a, $2y, $5 or $6

Add 'append: true' to write_files entries to append 'content' to file
specified by 'path' key. This modifies the file open mode to append.
|

In some environments, like FreeBSD, gpart can return the device basename
instead of the full path. If this discovered devpath does not exist and
is missing the '/dev/' prefix, add that prefix in an attempt to find the
device.
|

Fix a typo in a RuntimeError path. (udevamd -> udevadm).
|
|
Relax expectation on path to lxc and lxd. The deb path still does
install them in /usr/bin/ but that is overly pedantic.
Add a 'lxd waitready' (present since lxd 0.5) to wait until lxd
is ready before operating on it.

Cloud config can now disable ssh access to non-root users.
When defining the 'users' list in cloud-configuration a boolean
'ssh_redirect_user: true' can be provided to disable ssh logins for
that user. Any ssh 'public-keys' defined in cloud meta-data will be added
and disabled in .ssh/authorized_keys. Any attempts to ssh as this user
using acceptable ssh keys will be presented with a message like the
following:
Please login as the user "ubuntu" rather than the user "youruser".

In many cases, cloud-init uses 'util.subp' to run a subprocess.
This is not really desirable in our unit tests as it makes the tests
dependent upon existance of those utilities.
The change here is to modify the base test case class (CiTestCase) to
raise exception any time subp is called. Then, fix all callers.
For cases where subp is necessary or actually desired, we can use it
via
a.) context hander CiTestCase.allow_subp(value)
b.) class level self.allowed_subp = value
Both cases the value is a list of acceptable executable names that
will be called (essentially argv[0]).
Some cleanups in AltCloud were done as the code was being updated.

These tests focus on the apply_credentials method and the ssh setup for
root and a distro default user.

Pylint 2.0.0 was recently released and complains more about
logging-not-lazy than it used to. I've fixed those warnings, here.
The changes in rh_subscription are more extensive. pylint may be
complaining incorrectly there, but the tests were not correctly un-doing
all of their mock/patching. This cleans those up and makes pylint happy.

Newer versions (3.0.1+) of lxd create the 'lxdbr0' network when
'lxd init --auto' is invoked.
When cloud-init is given a network configuration to pass on to
lxc and that config had no name specified or 'lxdbr0', then cloud-init
would fail to create the network as it already exists.
Similarly, we need to remove the device from the default profile
so that the attach code can work.
Also, add a _lxc method and use it to make sure we're getting the
--force-local flag everywhere.

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.

Yaml tracebacks are generally hard to read for average users. Add a bit of
logic to util.yaml_load and schema validation to look for
YAMLError.context_marker or problem_marker line and column counts.
No longer log the full exceeption traceback from the yaml_load error,
instead just LOG.warning for the specific error and point to the offending
line and column where the problem exists.

Do not add new entries to /etc/fstab for devices that already have an
existing fstab entry.

The result of a read_file_or_url on a file and on a url would differ
in behavior.
str(UrlResponse) would return UrlResponse.contents.decode('utf-8')
while
str(FileResponse) would return str(FileResponse.contents)
The difference being "b'foo'" versus "foo".
As part of the general goal of cleaning util, move read_file_or_url
into url_helper.

This also makes some of the messages more consistent.

By default, FreeBSD's growfs runs interactively asking a question
which can be mitigated using the '-y' command line option. The fix
here is simply to pass -y to growfs to avoid the prompt.

The cloud-init-local.service expects that any network device name changes
have already been completed by the kernel or udev daemon.
In some situations we've found that the renaming of interfaces from kernel
names (eth0, eth1, etc) to their persistent names (eno1, ens3, enp0s1,
etc) may happen after cloud-init-local has started where it reads values
from sysfs about what network devices are present, and which device to use
as a fallback nic.
Subsequently, cloud-init-local would write out network configuration for a
kernel device name which would no longer be present by the time that
networking services start to bring up the devices. The result is that the
instance does not get networking configured. Prior to use of
systemd-networkd, the Ubuntu 'networking.service' unit included a call to
udevadm settle which is why this race is not seen on a Xenial system.
This change adds the ability to detect if an interface has a stable name,
if if we find one without stable names and stable names have not been
disabled (net.ifnames=0 in /proc/cmdline), then cloud-init will invoke
udevadm settle.

validate_cloudconfig_schema with strict=True would not actually validate
if there was no jsonschema available. That seems kind of strange.
The change here is to make it raise an exception if strict was passed in.
And then to fix the one test that needed a skipIfJsonSchema wrapper.

This admittedly does a fairly extensive re-factor to simply add a newline
to the end of sshd_config.
It makes the ssh_config updating portion of set_passwords more testable
and adds tests for that.
The new function is in 'update_ssh_config_lines' which allows you
to update a config with multiple changes even though only a single one
is currently used.
We also only restart the ssh daemon now if a change was made to the
config file. Before it was always restarted if the user specified
a value for ssh_pwauth other than 'unchanged'.
Thanks to Lorens Kockum for initial diagnosis and patch.

This enables warnings produced by pylint for unused variables (W0612),
and fixes the existing errors.
|

runcmd, bootcmd, snap/commands, ubuntu-advantage/commands would
log warning (and fail if strict) on duplicate values in the commands.
But those should be allowed. Example, it is perfectly valid to do:
runcmd: ['sleep 1', 'sleep 1']

The net-tools package is deprecated and will eventually be dropped. Use
"ip route", "link" or "address" instead of "ifconfig" or "route" calls.
Cloud-init can now run in an environment that no longer has net-tools.
This affects the network and route printing emitted to
cloud-config-output.log as well as the cc_disable_ec2_metadata module.
Additional changes:
- separate readResource and resourceLocation into standalone test
functions
- Fix ipv4 address rows to report scopes represented by ip addr show
- Formatted route/address ouput now handles multiple ipv4 and ipv6
addresses on a single interface

Python has deprecated these invalid string literals now
https://bugs.python.org/issue27364
and pycodestyle is identifying them with a W605 warning.
https://github.com/PyCQA/pycodestyle/pull/676
So basically, any use of \ not followed by one of [\'"abfnrtv]
or \ooo (octal) \xhh (hex) or a newline is invalid. This is most
comomnly seen for us in regex. To solve, you either:
a.) use a raw string r'...'
b.) correctly escape the \ that was not intended to be interpreted.

Add a base NTP client configuration dictionary and allow Distro
specific changes to be merged. Add a select client function which
implements logic to preferr installed clients over clients which
need to be installed. Also allow distributions to override the
cloud-init defaults.

The zfs/zpool commands will hang for 10 seconds if /dev/zfs is not
present (bug 1760173). This is a common occurence for containers
using zfs as rootfs. Additionally handle missing zpool command or
other errors that may occur while executing the zpool command.
|
|
Previously there was no support at all for zfs file system. With this
change it is now possible to use the resizefs module to grow a zpool to
its maximum partition size on FreeBSD.

The recently added snap and ubuntu_advantage modules had unit tests
that exercised jsonschema. Those throw error if jsonschema is
not present. Fix to skip in that scenario.

ubuntu-advantage-tools is a package for enabling and disabling extended
support services such as Extended Security Maintenance (ESM), Canonical
Livepatch and FIPS certified PPAs. Simplify Ubuntu Advantage setup on
machines by allowing users to provide a list of ubuntu-advantage commands
in cloud-config.

Support installing and configuring snaps on ubuntu systems. Now,
cloud-config files can provide a list or dictionary of snap:assertions
which will be allow configuration of snapd on a system via 'snap ack'
calls. The snap:commands configuration option supports arbitrary system
commands intended to interact with snappy's cli. This allows users to run
arbitrary snappy commands to create users, download, install and
configure snap packages and snapd.
This branch also deprecates old snappy and snap_config modules leaving
warnings in documentation and runtime for consumers of these modules.
Deprecated snap* modules will be dropped in cloud-init v.18.2 release.

Building doc would issue some warnings. This fixes all the warnings,
and changes the "code blocks" that were listed as 'bash' to instead
be 'shell-session'.

When instance meta-data provides hostname information, run
cc_set_hostname in the init-local or init-net stage before network
comes up.
Prevent an initial DHCP request which leaks the stock cloud-image default
hostname before the meta-data provided hostname was processed.
A leaked cloud-image hostname adversely affects Dynamic DNS which
would reallocate 'ubuntu' hostname in DNS to every instance brought up by
cloud-init. These instances would only update DNS to the cloud-init
configured hostname upon DHCP lease renewal.
This branch extends the get_hostname methods in datasource, cloud and
util to limit results to metadata_only to avoid extra cost of querying
the distro for hostname information if metadata does not provide that
information.

Previously the module was not working under FreeBSD due to a different
package name and some different paths. The module now has OS specific
default values which can even be customized via corresponding cloud config
variables.

This will provide a small performance improvement and shorter code.

Make puppet installation more configurable by:
- Adding a package_name parameter
- Exposing the puppet configuration and puppet ssl directories as
parameters. These default to the previous values if unset, but can be set
to the new values puppetlabs requires for its puppet 4.x packages. This
way puppet 4 configuration is now possible.

While salt grains can be configured in the minion config file, it is
usually better to configure it in the /etc/salt/grains file.
This allows that to be done.

While addressing undeclared variable in 'cloud-init status', I also fixed
the errors raised by automated code reviews against cloud-init master at
https://lgtm.com/projects/g/cloud-init/cloud-init/alerts
The following items are addressed:
* Fix 'cloud-init status':
* Only report 'running' state when any stage in
/run/cloud-init/status.json has a start time but no finished time.
Default start time to 0 if null.
* undeclared variable 'reason' now reports 'Cloud-init enabled by
systemd cloud-init-generator' when systemd enables cloud-init
* cc_rh_subscription.py util.subp return values aren't set during if an
exception is raised, use ProcessExecution as e instead.
* distros/freebsd.py:
* Drop repetitive looping over ipv4 and ipv6 nic lists.
* Initialize bsddev to 'NOTFOUND' in the event that no devs are
discovered
* declare nics_with_addresses = set() in broader scope outside
check_downable conditional
* cloudinit/util.py: Raise TypeError if mtype parameter isn't string,
iterable or None.
