I just saw in the trace output of a failure
> grep -o 'CentOS-.[^>]*GenericCloud-.[^>]*.qcow2'
> sort -r
> head -1
sort: fflush failed: 'standard output': Broken pipe
sort: write error
i.e. the "head -1" has exited after reading one line, but "sort -r"
still wants to write and thus has hit a pipe failure, and because we
run with "-o pipefail" this has halted the script.
This seems like it has been there more or less forever, maybe we just
got lucky hitting it now? Anyway, we can work around this by using a
process substitution and passing the output of this into head, this
way we won't hit a pipe failure.
I also updated the fedora path as it does the same thing.

This adds 9-stream support to the centos element.
See https://review.opendev.org/q/topic:cs9 for related patches.

The trvial fix allow override to work in air-gapped envirments where
the command 'curl -s https://cloud.centos.org/...' would fail.

This patch adds support for CentOS 8 Stream [1] to the centos element
(cloud image). Users should set DIB_RELEASE=8-stream.

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.

* Add "centos" element, a CentOS version-independent element. This is in
line with the same work done for RHEL in Stein cycle.
* Deprecate the centos7 element. CentOS 7 support itself it not
deprecated though. The new "centos" element provides the same support
level as the "centos7" element.
* Add functional testing
The default CentOS version is 8. You can adjust it using the DIB_RELEASE
environment variable.

Several people have popped up in IRC recently with failures in these
elements. Without Python 2.7 available in the image they are
unsupported (OpenStack hasn't supported it for a long time). Remove
these to avoid further confusion.
The centos/centos7 DISTRO split that has happened with centos-minimal
is unfortunate but I don't think it helps to rename centos7/rhel7 ATM.
To summarise; DISTRO=centos7 means image based build,
DISTRO=centos && DIB_RELEASE=7 means the minimal build.
In the future, I think it is important that the minimal builds and
image builds set the same DISTRO. This reflects that "upper" layers
shouldn't care about the exact building of the lower layers. I see
CentOS 8 going one of two ways
1) the changes are so significant, we start separate centos8 /
centos8-minimal elements. They both set DISTRO=centos8 (and
DIB_RELEASE to point-release maybe?). This means we have to update
all "if DISTRO == centos || DISTRO == centos7" branches to also check
for "centos8". Evenually (!) "centos" goes away for versioned DISTRO
only
2) we restore centos element with DISTRO=centos and DIB_RELEASE=8, and
centos-minimal remains the same. This means we have to audit all "if
DISTRO == centos" calls to make sure they're appropriate for version 8
(stick a "&& DIB_RELEASE=7" on them all basically).
I'm not sure we can fully decide until we start to see excatly how the
distro switching/matching bits look, but (2) is consistent with Ubuntu
and probably the preferred solution.
Some "rhel" parts have been cleaned up. More could be done in
rhel-common, but given our lack of coverage of that I'd prefer to
leave it for now.

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__.
