Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).
The problem with this is that editable/development installs (pip -e)
do *not* install data_files. Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.
data_files is really the wrong thing to use for what are essentially
assets of the program. data_files install works well for things like
config-files, init.d files or dropping documentation files.
By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from. In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].
We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.
Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.
I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.
Unfortunately, this has to move to work with setuptools. You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.
[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do. Essentially for us it's returning
__file__.

The centos cloud images are both arround a GB in size, and
downloading them causes lot of CI timeouts, downloading the
compressed version saves 700MB of bandwith and should save
a lot of time.

This change uses blkid to identify the fs type during redhat-common
extract-image. The image is mounted with -o nouuid for redhat/rhel
images that have XFS filesystems.
This is required when building images from the same base image
as the host VM to avoid "Filesystem has duplicate UUID" mount
failures.

The loopback handling in the Linux kernel limits the filenames of
files associated to loopback devices, see also linux/loop.h.
This is reflected also on userspace, as kpartx will silently do nothing
(exiting with 0) when requesting to remove a filename longer than 64
characters, as that name will obviously not match the truncated
filename. The result of this is that, when extracting qcow2 images for
the first time, if the qcow2 filename is long enough then the loopback
device will not be removed, remaining as stale in the host.
As a workaround, use a temporary file name when convering a qcow2 image
to raw, instead of using the base name of the qcow2 file.
While this still will not fix the issue when manually using a long
temporary directory (e.g. TMP_DIR=/very/long/etc...), at least should
avoid it in other cases.

it may happen that if the system where disk-image-create runs is busy,
then the kpartx -l run may leave a stale autodelete loop device.
This is because kpartx -l first adds a new loop device, then does the
listing and removes the loop device. The latter may not end before the
end of the kpartx run, leaving a loop device marked as autodelete.
Such kind of loop device will automatically delete itself, so the
rm -r $WORKING
after
sudo umount -f $WORKING/mnt
in the EXIT trap will fail because $WORKING does not exist anymore.
To prevent this situation, just ask udev to finish its operations,
properly removing the (temporary) loop device.

This is the centos element, which builds CentOS 6.
There are a couple of modifications to redhat-common because
the version of tar in el6 doesn't support --xattrs-include.
There is a change to both pkg-map and svc-map to add 'centos'
to the 'redhat' family.
Also explicitly have to install cloud-utils growroot and
dracut growpart for proper fsresize at instance launch.
Also sets the DIB_EXTLINUX variable because there is no grub2
for this distro.

There is a wide variety of tracing options through the various shell
scripts. Some use "set -eux", others explicity set xtrace and others
do nothing. There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.
This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE. All scripts have a stanza added to detect this and
turn on tracing. Any other tracing methods are rolled into this. So
the standard header is
---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
set -x
fi
set -eu
set -o pipefail
---
Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE. If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value. If they feel it should trace by default, they can modify
the default value also.
Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1". This was done by running [1] on patch set 15. See the thread
beginning at [2]
dib-lint is also updated to look for the variable being matched.

Patch adds support for PowerPC Big-endian and Little-endian local
fedora VM images and using VM images with two partitions, PReP
boot and root partition. Since PowerPC requires PReP boot
partition to be present.

Closes-Bug: 1413487
The way redhat-common's extract-image script was creating the base
tarball caused file capabilities to get dropped, which meant that
things like ping in RHEL 7 images was unusable for regular users.
This change adds the necessary options to the tar call to maintain
as many extended attributes as possible.
--acls and --selinux are intentionally omitted, and the selinux
xattrs are filtered out because all of those items cause issues
in our chroot environment. We restore selinux attributes at the
end of the build anyway so that shouldn't be a problem.

Update to newer Centos7 images as announced at [1].
Changes included:
* update to GA image
* respect TMP_DIR for image working directory
* use suffix-match rather than prefix-match to build RAW_IMAGE name
to be more robust against weird names
* partition layout work-arounds not needed any-more, all one
partition.
Resulting image booted locally with kvm and virtualbox (after
conversion to vdi)

When running inside a Docker container, we cannot rely on devices in
/dev/mapper to be automagically created by udev, because we probably
don't have a udev at all. To work around this, run dmsetup mknodes
after every kpartx run.

Initial support for a centos7 image.
This is separate to rhel7 because the major differences are things
like repo and image locations, which are always going to be different.
We should merge any real changes into the redhat-common layers.
Apart from the added support files in centos7/*, the other change is
mostly modifications to redhat-common's extract-image to handle
different partition layouts of the centos7 image.

As with the previous similar changes, this is intended to catch
problems as they happen instead of ignoring them and continuing on
to potentially fail later. Setting this on all existing scripts
will allow us to enforce use via Jenkins.
