According to man page `man 8 swapon', "Preallocated swap files are
supported on XFS since Linux 4.18". This patch checks for kernel version
before attepting to create swapfile, using dd for XFS only on kernel
versions <= 4.18 or btrfs.
Add new func util.kernel_version which returns a tuple of ints (major, minor)

DataSourceAzure: Gracefully handle the case of set hostname failure during provisioning
|
|
Add support for VMware's vCD configuration setting DEFAULT-RUN-POST-CUST-SCRIPT.
When set True, it will default vms to run post customization scripts if the VM has not been configured in VMTools with "enable-custom-scripts" set False.
Add datasource documentation with a bit more context about this interaction on VMware products.
With this fix, the behavior will be:
* If VM administrator doesn't want others to execute a script on this VM, VMtools can set "enable-custom-scripts" to false from the utility "vmware-toolbox-cmd".
* If VM administrator doesn't set value to "enable-custom-scripts", then by default this script is disabled for security purpose.
* For VMware's vCD product , the preference is to enable the script if "enable-custom-scripts" is not set. vCD will generate a configuration file with "DEFAULT-RUN-POST-CUST-SCRIPT" set to true. This flag works for both VMware customization engine and cloud-init.

(#483)
Problem: When cc_ca_certs configuration has both "remove-defaults: true"
and also specifies one, or more, new trusted CAs to add then the resultant
/etc/ca-certificates.conf file's 1st line is blank. As noted in comments
in the existing cc_ca_certs.py code blank lines in this file cause problems.
Fix: Before adding the cloud-init CA filename to this file first check the
size of the file - if is is empty (as all existing CAs have been deleted)
then write only the cloud-init CA filename to the file rather than appending
it to the file.

* cloudinit: remove global disable of pylint W0107 and fix errors
This includes removing a test class which contained no tests but wasn't
detected as empty because of an errant pass statement.
* .pylintrc: update disable comment to match arguments

This includes a fix to a test that had a string concatenation issue, and
so was only testing a prefix of what was intended.

I've been seeing intermittent failures of this test, and I tracked it
down to something to do with`test_features.py`: running this test after
`test_features.py` causes the failure, but the inverse does not.
This fixed patch ensures that the test will pass regardless of ordering.

Do not fail if /etc/fstab is not present. Some images, like container
rootfs may not include this file by default.
LP: #1886531

Update lxd_export method to detect and handle different image formats
cloud_tests will only support the "split" type images which exports a
compressed (xz) tarball of metadata and a rootfs (of different formats).
For non-split image formats (single tarball with metadata + rootfs) we now
raise an exception indicating that the requested image is not supported
at this time.

This is an improvement over indirect parameterisation for a few reasons:
* The test code is much easier to read, the mark names are much more
intuitive than the indirect parameterisation invocation, and there's
less boilerplate to boot
* The fixture no longer has to overload the single parameter that
fixtures can take with multiple meanings

For versions before 20.2, we allowed the use of ec2 mirrors if the datasource availability_zone matches one of the ec2 regions. We are now updating that behavior to allow allow the use of ec2 mirrors on ec2 instances or if the user directly passes an an ec2 mirror url through #cloud-config apt directives.

Changes are made that simplify code and aim to properly support FreeBSD:
- use `util.find_devs_with` instead call directly `blkid`, because on FreeBSD is not supported well and `util.find_devs_with` have solution for FreeBSD for that
- introduction of an additional name on FAT file system, which is used in FreeBSD
- drop shell to use default value, because FreeBSD – by default – does not have `/bin/bash`

Create a schema object for the chef module and validate this schema in the handle function of the module.
Some of the config keys description, so I tried looking at the code and chef documentation to provide an information to the user. However, I don't know if I have the best description for all fields. For example, for the key show_time I could not find an accurate description of what it did, so I used what was in our code base to infer what it should do.

Hetzner cloud only supports user-data as a string (presumably utf-8).
In order to allow users on Hetzner to provide binary data to cloud-init,
we will attempt to base64decode the userdata.
The change here adds a 'maybe_b64decode' function that will decode data
if and only if is base64 encoded.
The reason for not using util.b64d is that we do not want the return value
decoded to a string, and util.b64d will do that if it can. Additionally
we call decode with validate=True which oddly is not the default.

This allows us to disable the `ensure_dir` call when it isn't
appropriate.

This introduces a way to log the dhclient error stream, and uses it for the Azure datasource (where we have a specific requirement for this data to be logged).

When updating the docstring to include it, I realised that the current
name is somewhat misleading; this makes it a little easier to
understand, I think.

Reason: commit ded1ec8 introduced a regression whereby a bridge with no "parameters:" setting caused a KeyError exception.

* test_opennebula: convert TestParseShellConfig to a pytest test
And allow it to run bash.
(We aren't aiming to convert TestCase tests to pytest tests as a rule.
In this case, I needed to change its implementation to limit subp usage,
and I chose pytest over CiTestCase.)
* test: move conftest.py to top-level, to cover tests/ also
This gives us a single conftest.py which is shared by all tests in the
project.

This was painful, but it finishes a TODO from cloudinit/subp.py.
It moves the following from util to subp:
ProcessExecutionError
subp
which
target_path
I moved subp_blob_in_tempfile into cc_chef, which is its only caller.
That saved us from having to deal with it using write_file
and temp_utils from subp (which does not import any cloudinit things now).
It is arguable that 'target_path' could be moved to a 'path_utils' or
something, but in order to use it from subp and also from utils,
we had to get it out of utils.

Build time feature flags are now defined in cloudinit/features.py.
Feature flags can be added to toggle configuration options or
deprecated features. Feature flag overrides can be placed in
cloudinit/feature_overrides.py. Further documentation can be found in
HACKING.rst.
Additionally, updated default behavior to exit with an exception
if #include can't retrieve resources as expected. This behavior
can be toggled with a feature flag.

This ensures that Travis will not kill our tests if fetching images is
taking a long time.
In implementation terms, this introduces a context manager which will
spin up a multiprocessing.Process in the background and print a dot to
stdout every 10 seconds. The process is terminated when the context
manager exits.
This also drop the use of travis_wait, which was being used to work
around this issue.

Create a schema object for the `apt_configure` module and
validate this schema in the `handle` function of the module.
There are some considerations regarding this PR:
* The `primary` and `security` keys have the exact same properties. I
tried to eliminate this redundancy by moving their properties to a
common place and then just referencing it for both security and
primary. Similar to what is documented here:
https://json-schema.org/understanding-json-schema/structuring.html
under the `Reuse` paragraph. However, this approach does not work,
because the `#` pointer goes to the beginning of the file, which is
a python module instead of a json file, not allowing the pointer to
find the correct definition. What I did was to create a separate dict
for the mirror config and reuse it for primary and security, but
maybe there are better approaches to do that.
* There was no documentation for the config `debconf_selections`. I
tried to infer what it supposed to do by looking at the code and the
`debconf-set-selections` manpage, but my description may not be
accurate or complete.
* Add a _parse_description function to schema.py to render multi-line
preformatted content instead of squashing all whitespace

Move from 127.0.0.1 to 127.0.1.1 for localhost IP addr for opensuse and sles

Add a unit test to validate if the examples provided in the config
modules are conforming to the concatenated schema of all config
modules. The rationale behind that is not only to verify if the
examples are correctly written but to assert that no config schema
is interfering with each other.
Failures in validate_cloudconfig_schema raise the
SchemaValidationError by using strict=True, so I have
only called the function passing the right schema examples to
validate.
This branch also fixes an invalid schema example in cc_snap.

Implement the upgrade support:
- FreeBSD: using `pkg upgrade`
- NetBSD: with `pkgin`

We want to set route-metrics such that NICs are configured with the priority that they are given in the network metadata that we receive from the IMDS. (This switches away from using MAC ordering.)
This also required the following test changes:
* reverse the sort order of the MACs in test data (so that they would trigger the bug being fixed)
* fix up the key names in `NIC2_MD` (which were under_scored instead of dash-separated)
* use a full interface dict (rather than a minimal one) for `TestConvertEc2MetadataNetworkConfig`

Add schema definition to cc_write_files.py
Cloud-config containing write_files config directives will now
emit warnings for invalid config keys or values for the write_files
module.
Add an extension to JSON schema's draft4validator to permit either
binary or text values for 'string' objects.
This allows for JSON schema validating the YAML declaration of binary
valiues in cloud-config using YAML's '!!binary' syntax.
Add the ability to pass a specific module name to
`cloud-init devel schema --docs <module_name>|all` to optionally
limit doc output during development to a single schema doc.

These libraries provide backports of Python 3's stdlib components to Python 2. As we only support Python 3, we can simply use the stdlib now. This pull request does the following:
* removes some unneeded compatibility code for the old spelling of `assertRaisesRegex`
* replaces invocations of the Python 2-only `assertItemsEqual` with its new name, `assertCountEqual`
* replaces all usage of `unittest2` with `unittest`
* replaces all usage of `contextlib2` with `contextlib`
* drops `unittest2` and `contextlib2` from requirements files and tox.ini
It also rewrites some `test_azure` helpers to use bare asserts. We were seeing a strange error in xenial builds of this branch which appear to be stemming from the AssertionError that pytest produces being _different_ from the standard AssertionError. This means that the modified helpers weren't behaving correctly, because they weren't catching AssertionErrors as one would expect. (I believe this is related, in some way, to https://github.com/pytest-dev/pytest/issues/645, but the only version of pytest where we're affected is so far in the past that it's not worth pursuing it any further as we have a workaround.)

We currently have a test system where get_interfaces_by_mac raises an

get_interfaces_by_mac out.
