With the removal of Python 2.x we can remove the unittest2 compat
wrappers and switch to assertCountEqual instead of assertItemsEqual
We have been able to use them since then, because
testtools required unittest2, which still included it. With testtools
removing Python 2.7 support [3][4], we will lose support for
assertItemsEqual, so we should switch to use assertCountEqual.

DIB was retrieving the oldest cloud image file which, presently, means
retrieving CentOS 8.1 instead of CentOS 8.2. Even though DIB runs a
system update and so catches up to latest, this takes bandwidth, time
and final image space (8.1 + system update = 765M qcow2, vs 8.2 + system
update = 518M qcow2).
This patch fixes that by taking the first image name in a descending
order list.

Since the original merge of this code
(04208e7c79) several things have
changed; particularly now we ship dib-run-parts as part of dib, not as
a separate package.
We setup $_LIB to point to the shipped library diretory via
pkg_resources lookups. We now call dib-run-parts (as mentioned,
shipped as a dib library now), source scripts, etc. via $_LIB and thus
do not rely on $PATH. Consequently we don't need this activation
part.
Which is helpful, because "venv" (as opposed to virtualenv) doesn't
have activate_this.py. So this fixes installation under that for
Python 3.
We update the functional tests to use the virtualenv_command exported
by the ensure-pip role, which will test the venv path. There is no
need for dib_python as we are Python 3 only now.

This reverts commit 6ee2995214 and
e85c2a6f03.
I missed that if you pip install and then run dib-lint, it's not going
to pick up the .yamllint file shipped here. Thus it gives spurious
errors.
The reason for this was simply better duplicate key detection in yaml
files, which caused us problems with the kernel installs. However, at
this point it seems just the old "does it load" test from pyyaml will
be enough.

As of recently, opensuse-minimal images fail to build because of an
error installing the kernel-default package:
> Problem: kernel-default-5.6.12-1.3.x86_64 requires mkinitrd >= 2.7.1, but this requirement cannot be provided
> not installable providers: dracut-050+suse.61.g0fe0e854-1.1.i586[repo-oss]
> dracut-050+suse.61.g0fe0e854-1.1.x86_64[repo-oss]
The problem is there is a recently added package `busybox-links` which
provides a subpackage `busybox-xz` which provides the /usr/bin/xz
utility. Since this is available, the `aaa_base` package installs it
during the root.d base installation phase to fulfill it's dependency on
/usr/bin/xz. On the other hand, the dracut package explicitly requires
the `xz` package, and this is not co-installable with the `busybox-xz`
package, so the dracut package is not installable during the install.d
phase. This change explicitly adds the `xz` package to the initial
chroot provisioning phase so that the /usr/bin/xz requirement is already
fulfilled and `busybox-xz` does not get installed.

This reverts commit 6e549c33ac.

The change Ia6f10741fa6be24b11d6991c8a6b6e07951ff68d introduced having
"when:" as a list of values. However, this was actually not
sufficient to express the logic required for arm64/x86_64/xenial
kernel matching we wanted.
Because the package name is a key, we can't have multiple entires in
the package-map YAML files. This means we can't do more advanced
matching and thus we need to be able to match through multiple
parameters. Similar to Ia6f10741fa6be24b11d6991c8a6b6e07951ff68d we
modify the matching rules to allow a list.
A an example of using this is provided in the README.rst, and this
same example worked through by the unit tests.
This also slightly updates the matching logic to be more sequential.
After each check we either continue on or log the failure and continue
to the next check (rather than set a list of flags then check that at
the end). This makes it much easier to understand what is being
matched in the logging output from the tool.

This is an alternative approach to commit
68bb43535e. I think this proposes a
better overall solution that the prior change which had the Python 3
packages being installed, but did not specify the _do_py3 flag to do
the installation steps that redirect the various tool installations.
Fedora 31+ doesn't have python2, and Tumbleweed does have some Python
2 support but there seems to be no reason to bother updating this
element for either with infra very close to removing this completely
[1]. Error out on these platforms, and add a release note.
The 15 path should include the python2 and python3 packages, along
with the flags to do the "cleanup"; i.e. forced removal of distutils
packages that pip 10+ won't touch. As mentioned in the original
change, the six package causes problems here, but we can clear that
too by explicitly listing it instead of letting it come in via
dependencies. Again, this element will be removed from the infra 15
builds ASAP; but we can release with this to provide a roll-back point
if we need to revert the removal to fix things temporarily.
Add it to the testing path as well.

Make sure rngd, a hardware RNG entropy gatherer daemon, is installed on
all DIB-built Red Hat family distro images. rngd comes installed by
default in a typical base installation as it's proven to help speed

Some phases of diskimage-builder run outside the chroot environment,

This means these scripts may choose the wrong python version by using

This patch creates a temporary directory and symbolic link for the

The vhdutil utility is completely dead; the whole subsystem it relies
on was removed with [1] so it's not even vaguely possible to keep it
up-to-date.
I took the .raw images on a nb and used the qemu-img there (so Xenial)
and generated some VPC images; uploaded them to rackspace and the all
seemed to boot fine. If there was a problem, maybe it's been fixed on
either the qemu or RAX side in the previous few years.
Thus swith to qemu-img to generate the vhd images too.

With the introduction of centos 8 we have constructs like
if [[ $DISTRO =~ (centos|fedora) && $DIB_RELEASE -ge 8 ]]
This is intended to match the "centos7" element (from the =~) but it
was missed that this is setting the DIB_RELEASE to "GenericCloud".
I think it makes more sense for this to be a numeric release, and
makes constructs like above work. There really isn't any other type
of image to choose here; thus we move it into a new, centos7
specific variable.
Note that when the centos 8 images are available, we want to move to a
generic "centos" element that will handle both 7 and 8 together (same
as rhel) based on DIB_RELEASE and deprecate centos7; this works with
that environment too.

NetworkManager with simple-init has proven to be stable in OpenStack

As described inline, deprecate the "source" install for CentOS 8.
Overwriting the packaged tools has long been a pain-point in our
images, and the best outcome is just not to play the game [1].
However, the landscape remains complicated. For example, RHEL/CentOS
8 introduces the separate "platform-python" binary, which seems like
the right tool to install platform tools like "glean" (simple-init)
with. However, platform-python doesn't have virtualenv (only the
inbuilt venv).
So that every element doesn't have to hard-code in workarounds for
these various layouts, create two new variables DIB_PYTHON_PIP and
DIB_PYTHON_VIRTUALENV to just "do the right thing". If you need is
"install a pip package" or "create a virtualenv" this should work on
all the platforms we support. If you know more specifically what you
want (e.g. must be a python3 virtualenv) then nothing stops elements
calling that directly (e.g. python3 -m virtualenv create); these are
just helper wrappers for base elements that need to be broadly
compatible.

Install the Python 3 libselinux packages for Fedora platforms. I
think this is the right choice; Fedora is a Python-3 only distro so we
shouldn't default to installing the python2 libraries.
This has a practical effect if you're using Ansible with
ansible_python_interpreter=/usr/bin/python3 as it needs these
packages.
There is some small chance of breakage if you're using Ansible still
with Python 2, I guess. In infra I notice we bring this in with
"zuul-worker" project-config element. On balance, I think that if you
need the Python 2 packages for some reason, it should be a special
install and not part of redhat-common.

Two bugs are addressed.
1) The sysprep element was broken in that it only truncates
/etc/machine-id, but not /var/lib/dbus/machine-id. systemd will
not generate a new machine-id if /var/lib/dbus/machine-id is
present[1], it will simply copy it to /etc/machine-id.
We observed machine-ids being packaged in /var/lib/dbus/machine-id
on several distros: Ubuntu Bionic, Fedora 29, Debian Stretch.
CentOS 7 and Ubuntu Xenial do not contain packaged machine-id as
far as I can tell.
All test builds were performed using -minimal elements.
2) A second bug existed where debian-minimal did not run the sysprep
element at all, so a stretch image I tested contained a populated
/etc/machine-id AND a populated /var/lib/dbus/machine-id.

linux-firmware and linux-firmware-whence (meta package for mostly iwl
firmwares) packages account for approx. 289 M install size on a F30
system, and linux-firmware for approx. 176 M on CentOS 7. Users needing
these firmwares are eventually baremetal users and are not looking for a
very minimal operating system base install like virtual image users are.
Thus, a non-minimal OS element is better suited for them. Alternatively,
it could be later considered a dedicated firmware element.

This is a follow-on to I475a253091cbaf63687b91c748c31a6753bb0f57 as we
are still seeing issues on some clouds with unconfigured networking.
We increase the timeout, but also make it configurable so we can
fiddle it without a dib release in the gate.
To follow-on from the experimentation done by clarkb, I can confirm by
emperical testing on a Centos 7 image (from today, today being this
change's date) that setting
net.ipv6.conf.all.autoconf=0
by itself is "fatal" and the interfaces do not come up; i.e. nm does
not by default seem to re-enable ipv6 for the interface. However,
explicitly adding:
IPV6INIT=yes
IPV6_AUTOCONF=yes
to the interface file *does* seem to make it work, even if
"all.autoconf=0" is set (then again, there's also bugs about the
effect of this [1]). However, no extant distribution (I can currently
find) does anything like this by default.
If this continues, this may be an option. Another might be to avoid
the use of the nm-settings-ifcfg-rh profiles and move directly to nm
ini files with glean.

Something (possibly [1], but that change is at best cryptic) has

As noted in the change, 7fd52ba841
increased the size of the EFI partition considerably. This has meant
that our padding upwards of the disk size is insufficient and EFI
builds (arm64 in particular) is failing due to out-of-disk errors
during final image operations like installing kernels.
Similar to the discussion we had in
I65fa13a088eecdfe61636678578577ea2cfb3c0c, this feels a bit ugly
because we're mixing logic here with sizes specified in block-device
config files. But it boils down to the same problem; we are
calculating the disk size here and passing it to the block-layer, so
unless we want to make large changes to the status quo about where
these sizes are calculated, small adjustments here are the most KISS
solution.
Thus we check if we have selected the EFI bootloader element, and thus
assume there will be a large system EFI partition and expand the disk
size accordingly.

The linux kernel and NetworkManager fight each other over control for
interface management when router advertisements are in use. Long story
short if the linux kernel configures a network interface for ipv6
before NetworkManager attempts to manage that interface then NM will
ignore the interface and not configure ipv4 on it.
This can happen because the kernel is configured to send router
advertisements solicitations which result in router advertisements which
the kernel uses to configure the interface(s). There is a default of a 1
second delay before sending the solicitation which in many cases is long
enough that NM has started before then. However, in slower environments
like those used for testing with qemu this isn't long enough.
Some testing by hand indicates that 15 seconds is about right so
increase the delay to 15 seconds via sysctl.conf.
Note this may increase boot times in ipv6 only environments (though it
is hard to be sure due to how systemd starts everything at once and does
socket activation and the like).

While 12 MiB is enough to fit shim-x64 and grub2-efi-x64, yum fails to
update these packages to newer versions:
Transaction check error:
installing package shim-x64-15-2.el7.centos.x86_64 needs 7MB on the /boot/efi filesystem
installing package grub2-efi-x64-1:2.02-0.76.el7.centos.1.x86_64 needs 3MB on the /boot/efi filesystem
Error Summary
-------------
Disk Requirements:
At least 7MB more space needed on the /boot/efi filesystem.
It is recommended that the ESP partition be much bigger. This commit
bumps its size to 550MiB, following guidelines from Rod Smith to avoid
incompatibilities with some EFIs [1].

Avoids failing on the first attempt to download the image to cache as
mirrors hosting them can randomly go down, usually with a connection
refused.

When the mirror returns a error, it was trying to interpret the error
message (e.g. <html><title>Internal server error..) as a download link.
By using -f on curl we get an empty reply and an exit code, which, as
we run in set -e mode, aborts.

The rhel7 element is deprecated and is left only for backward
compatibility.
The rhel element should be used instead. Users should set DIB_RELEASE to
'7' to indicate which release you are using.
The new element is a version-less RHEL element to handle both '7'
and '8' DIB_RELEASE, which aligns with other elements which operate in
the same way such as the Fedora element.

Make a version-less RHEL element to handle both '7' and '8' DIB_RELEASE.
The element usage should align with other elements which operate in the
same way such as the Fedora element.
Additionally, this patch adds support for RHEL8 that operates with
Python 3.
As of now, users of diskimage-builder will still be able to use the
'rhel7' element, or migrate to 'rhel' and specify their respective
DIB_RELEASE value.
* mount the xfs file-system for extraction as read-only. vaguely
based on explaination in [1] and the fact we only read the image
data into a tar, so can ignore this.
XFS (dm-1): Superblock has unknown read-only compatible features (0x4) enabled.
* Use the redhat system python as the dib-python version. dib was
ahead of it's time making an abstracted python interpreter for
system work ;) the system python should work for running the various
dib element scripts.

I want to use the new --image-extra-size flag[1] but my use-case
calls for megabyte granularity of this value. Rather than adding
60% to an 800MB image, maybe I only want to add 100 or 200MB, etc.

Use openSUSE 15.0 as default, which is the latest released stable
openSUSE release. Switch to https for accessing download.o.org
as encrypted transfers should be used by default.
Remove leftovers for definitely unmaintained openSUSE 13.x images
and split into old/new leap style versioning scheme for clarity.

It looks like fedora-release on fedora 30+ has been split into sub
packages. Use fedora-release-common to avoid package conflicts.

Depending on the version of $DIB_PYTHON_VERSION, we can either use pip /
pip3 to install glean. This is helpful for newer OSes that might not
want to ship python2 (pip).

Currently diskimage-builder supports two ways to specify the image
size. One is defining a fixed image size using DIB_IMAGE_SIZE, the
other one is auto-detection while adding a security margin of 60% as
free space. This means when building larger images (e.g. >100GB) with
unknown size upfront we end up with much wasted space, IO and network
traffic when uploading the images to several cloud providers. This can
be optimized by adding a third way by defining DIB_IMAGE_EXTRA_SIZE to
specify the free space in GB. This makes it possible to easily build
images of varying sizes while still minimizing the overhead by keeping
the free space constant to e.g. 1GB.
