It has always been a weird thing that dib is a python package, but
is totally driven by the disk-image-create script. It creates this
strange division that is hard to explain.
This moves disk-image-create to a regular python entry-point
Currently, this simply exec()s the original disk-image-create script.
However, we now have a (private) interface between disk-image-create
written in python and the driver shell script. Here's some things we
could do, for example:
* Argument parsing is generally nicer in Python, and then end result
is mostly just setting environment variables to flag different things
in the shell script. I could see us moving the argument-parsing into
diskimage_builder.disk_image_create:main() and just setting things in
os.environ before the exec()).
* I7092e1845942f249175933d67ab121188f3511fd sets IMAGE_ELEMENT_YAML in
disk-image-create by calling-back to element-info. We can just call
element_dependencies.find_all_elements() in here an export is to
os.environ before disk-image-create starts.
* remove need for ramdisk-image-create symlink by just exporting
IS_RAMDISK based on sys.argv[1] value
* you could even unit test some of this :)

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__.

Running the functional tests is time consuming. This patch adds the
option `-j <job count>` to the tests/run_functests.sh: when given the
test run in parallel up the <job count> jobs.
When using this, be sure to have enough resources (CPUs, RAM and HD
space) on the host.
In addition there was the need to change two things:
o Global /tmp/dib-test-should-fail was move to temporary build
directory of each execution.
o Because the logs might now interleave, each log line has now a
prefix of the name of the testcase.
[In my environment running functests sequential takes 15+ minutes,
running them parallel takes less than 6 minutes.]

This patch solves three issues with Debian packaging / apt:
o When building 'testing' only default apt sources is
included - backports, updates and security are skipped because they
do not exists.
o The default release for Debian was `unstable`: this is now fixed to
`stable`.
o Starting a Debian Stretch VM that was build with diskimage-builder
does not work, because some mandatory packages are missing.
This patch fixes this problem: it adds the mandatory packages and
the test case.

We have some test cases which attempt to build docker images, therefore
we need docker.
Fix a few bugs that showed up when we run docker tests - we need to
docker rm with sudo and docker images don't always have a /tmp so check
before unmounting it.

lib/img-functions:finalise_base() does a recursive unmount of /tmp to
cleanup any old mounts that might be in there (we do things like bind
mount caches in there). unmount_dir fails if /tmp isn't a
directory.
The 'run_output_format_test.sh' uses the 'fake-os' element for
testing. Because 'fake-os' did not create the '/tmp' directory, the
test script fails.
This patch fixes the problem: it adds '/tmp' to the list of
directories that are created.
It was implemented replacing the existing five 'mkdir'
command with a for loop over now six directories.

This was not well tested. Build the argument into a variable which
can be eval()ed to produce the final output.
Add the flag so we test this during functional tests. Add "-x" to dib
invocations so we can more easily debug failures.

This commit adds testing for the gentoo element based off of the debian
element. In adding testing support a couple of additional errors were
found and corrected, namely the following.
* shm is not in /proc/mounts though it is valid for use based off of
the sticky flag.
* The path in ELEMENTS_PATH needs to be pruned to be usable.
* Added uuidgen-runtime to the list of packages installed for Ubuntu
as the new ubuntu-trusty image does not ship with it.

universal that zerofree. The related-id has the patchset that implements
fstrim.

If the image has an ext filesystem and the zerofree utility is present
on the build system then run zerofree. This should make images as
compressable as possible which is a nice feature when building
compressed qcow2 images.

This simplifies and enhances the functional-test runner script for
much better interactive behaviour and to give us the ability to better
choose what is running in CI.
Firstly, I have split the image-output testing into a separate script.
This is not actually part of the functional testing of elements and is
both logically and functionally different. It currently does not run
in upstream CI because we don't have docker in the images. I have
nothing against it, but it can be it's own thing.
run_functests.sh is overhauled to have a useful interactive interface,
e.g.
---
$ ./run_functests.sh -h
run_functests.sh [-h] [-l] <test> <test> ...
-h : show this help
-l : list available tests
<test> : functional test to run
Special test 'all' will run all tests
$ ./run_functests.sh -l
The available functional tests are:
apt-sources/test-sources
debian/build-succeeds
fedora/build-succeeds
fedora/build-succeeds-f21
ironic-agent/build-succeeds-fedora
---
As described there, you can run a single test, a number of tests, the
default tests (as CI will do) or all tests. Running all tests is too
much for regular CI, but currently the only way to stop a low priority
test running, or temporarily pause is to remove it completely --
clearly sub-optimal (see I93c2990472e88ab3e5ff14db56b4ff1b4dd965ef).
There is nothing complicated about this, and to further simplify I
have merged the runner functions back into run_functests.sh which
remains a very modest ~150 lines, with most of that being argument
sanity. With that and the image-format cleanup, we can remove the
indirection of the 3 small library files.
For consistency, I have renamed the "dib_functions_test" (that tests
things from the dib functions library) with a run_* prefix.
Because the default list is the same as the current functional tests
run, this does not modify the status-quo. I plan to modify this,
however, to run fedora-minimal & centos-minimal tests in a future
change, as these are required to be stable for openstack ci.
Documentation is updated, and a README.rst is added in the tests
directory for discoverability.

I noticed when running functional tests via a interactive shell they
would end up hanging; I tracked it down to waiting for input on this
tar command. We need to specify "-f" so it opens the file ...
---
| + tar -t /tmp/tmp.qid2Ygfu7v/image.tar
| + grep -q /tmp/dib-test-should-fail
| tar: This does not look like a tar archive
| tar: /tmp/tmp.qid2Ygfu7v/image.tar: Not found in archive
| tar: Exiting with failure status due to previous errors
---
I guess we never noticed because it's always running in CI where stdin
is closed and it just get that nothing read above. This probably was
reversing the logic of the "should have failed" tests ... but I don't
think we take that path currently for any tests.

Cleanup this function to work with a symlinked directory. Document
it's behaviour more exactly, and add a simple unit-test for it (not
run by default, due to doing things like mounting and unmounting
system dirs on a live system, which doesn't seem safe for CI. But it
is useful for developers ensuring sanity).

We perform a check for this file after an image build fails to see if it
was intentional. This outputs a message which looks like the failure is
a result of the check when the file is missing which is very confusing
to users. Lets be more quiet about it.
