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.

We should make use of the CentOS-7-x86_64-GenericCloud.qcow2 symlink from
http://cloud.centos.org/centos/7/images/ instead of having a hard coded cloud
image. Specific cloud images can still be downloaded by overriding
$DIB_RELEASE.
More importantly, using the symlink will keep us automatically up to date with
the latest CentOS 7 cloud image. The image in use by the hard coded value
occassionally exhibits "No space left on device" errors after the cloud-init
filesystem resize. More info about this issue is at:
http://xfs.org/index.php/XFS_FAQ#Q:_Why_do_I_receive_No_space_left_on_device_after_xfs_growfs.3F
The newer cloud image (with a newer kernel) does not exhibit this issue.

rhel7 and centos7 images are both only available on x86_64 arch.
if $ARCH is misconfigured, some strange error will happen during the build.
For example, DIB will try to install EPEL i386 on the 64bit root system.
For the record, tripleo-incubator $NODE_ARCH default value is i386. The
problem will happend as soon as the default value is used with one of
these root elements.
This commit ensure the $ARCH is set to amd64 as soon as the centos7 or
rhel7 root element are used.

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.

This is the final released image; it is the same one deployed in many
cloud provers such as HP and AWS. It is also safe from all known
vulnerabilities up to its release

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)

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.
