Many programs rely upon /etc/protocols to be present
however the default debian image that is generated lacks
/etc/protocols. This is observable when building an image
for use with ironic via the ironic-agent element, since
the IPA agent fails to start as python needs /etc/protocols
to open a socket connection.
Added to debian-minimal as it is inherited into the debian

Change I008f8bbc9c8414ce948c601e3907e27764e15a52 has shown that we
build redhat images without the "semange" tool available, which comes
from the policycoreutils-python package (see also
I3f9e2c322d042a5dddba33451c0fc21a4d32a88a).
I403e7806ae10d5dd96d0727832f4da20e34b94c7 added some of the selinux
libraries to yum-minimal for ansible support, but not to others.
Given both these changes, it seems that selinux[-targeted],
libselinux[-python] and policycoreutils[-python] can reasonably
considered part of all base images. Move the selinux related packages
into redhat-common.
This also adds it explicitly to install_test_deps.sh. It was actually
being dragged in by the docker install, but is a required component
for building (should be in bindep, but not there with that yet).

The MBR Partition Table Entry (PTE) allows one to specify many
possible partition types and one of the benefits of this is being able
to specify the CHS variant or the LBA variant.
By default, LBA only creates partitions of type 0x83 (of course,
that's only because the documentation doesn't tell you how to make it
do anything else).
I will take up Ian's suggestion in patch set 2 for a more rigorous

Currently, the cleanup script is using existence of

this is misleading and can lead to problems when selinux

As described in the comments inline, on a selinux enabled kernel (such
as a centos build host) you need to have permissions to change the
contexts to those the kernel doesn't understand -- such as when you're
building a fedora image.
For some reason, setfiles has an arbitrary limit of 10 errors before
it stops. I believe we previously had 9 errors (this mean 9
mis-labeled files, which were just waiting to cause problems).
Something changed with F26 setfiles and it started erroring
immediately, which lead to investigation. Infra builds, on
non-selinux Ubuntu kernel's, would not have hit this issue.
This means we need to move this to run with a manual chroot into the
image under restorecon.
I'm really not sure why ironic-agent removes all the selinux tools
from the image, it seems like an over-optimisation (it's been like
that since Id6333ca5d99716ccad75ea1964896acf371fa72a). Keep them so
we can run the relabel.

As described in the comment and associated bugzilla, the behaviour of

setfiles call that does nothing without this.

As described in the referenced bug, the dependency solver in yum

In preparation for promoting the openSUSE jobs to voting ones we should
use the OpenStack mirrors. As such, the opensuse elements are modified
to make use of the DIB_DISTRIBUTION_MIRROR variable which is normally

We added the DIB_distro_DISTRIBUTION_MIRROR arguments with
I92964b17ec3e47cf97e3a3091f054b2a205ac768 as a way that we could
source a list of mirrors and then have the distro elements choose
which one applied to them.
However, this hasn't worked out to be so useful. The
openstack-ci-mirrors element is working as a mirror setup script -- it
translates the openstack CI mirror list variables into the generic
"DIB_DISTRIBUTION_MIRROR" as appropriate for each distro's build.
Also, it turns out there's other things that need to be done, such as
turning off gpg checking, which mean the idea of "just export
variables" hasn't turned out as valid ... you need actual code
involved to get it right.
AFAICT we never actually documented these, and they do not seem to be
in use. They have caused considerable confusion when dealing with new
platforms as we try to keep consistency. Remove them.

We replace the base resolv.conf with an "outside" copy so that
resolving works when we're in the chroot.
Installing resolvconf package modifies the in-chroot resolv.conf to a
symlink (to /var/run) which it wants maintained in the final image.
We have the existing "immutable" check for a created resolv.conf file,
but no eqivalent for a symlink.
This adds a check to see if the resolv.conf is a symlink and leave it
alone if it is, assuming it has been re-created in the chroot.
I have tested this with ubuntu-minimal+resolvconf with
dhcp-all-interfaces and the system seems to work with resolvconf

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.

The image download tests have long been too unreliable for the gate.
We need to cache the base images similar to how devstack caches it's
testing images. Let's move them to non-voting jobs for the time
being.
This means that the gate jobs are now all based on "-minimal" and are
using infra mirrors. Unfortunately, there is still some unreliability
because we currently have issues with infra mirrors being very slow
after AFS updates, leading to job timeouts. But we're on the right
path...
Also, I noticed we don't have tests of the "ubuntu" image-download
based tests, which were tacitly being tested by apt-sources before we
moved that to -minimal. Add simple tests for these.

I'm uncertain as to why this is using the "fedora" element for testing

the gate.

This adds "openstack-ci-mirrors" element which performs various
settings to get builds using local mirrors. As a first step, we
convert ubuntu-minimal jobs
The main trick is that since infra mirrors are created with rerepo
they are not signed (they are recreated, not cloned, and not signing
is seen as a feature in that it deters external use). So we need to
instruct debootstrap to ignore signing and also turn it off for
in-chroot apt. Other than that, the existing DIB_DISTRIBUTION_MIRROR
works to redirect installs.
Remove "restricted" as it's not mirrored, and I don't think we want it
in here by default.
(I think DIB_DISTRIBUTION_MIRROR is a bit of an anti-pattern, because
it leaves the mirrors in the final image -- just because you use them
to build, doesn't mean you want them at runtime). But we don't need
to fix that now, and we don't use any created images.)
This pauses fedora testing until the next change, which moves to using
local mirrors for testing on fedora/centos

We introduced the "settle" in
I90103b59357edebbac7a641e8980cb282d37561b thinking that maybe kpartx
had not finished writing the partition. This probably wasn't a bad
first assumption, since we used to have this -- but is seems
insufficient.
The other failiure here seems to be if kpartx hasn't actually seen the
updated partition table in the image, so it has correctly (in it's
mind) not mounted the partition.
Looking at strace of fdisk run manually on a loopback, it will do a
fsync on the raw device after writing and then a global sync as it
exits.
This replicates this; we flush and fsync in mbr.py in the exit handler
after writing the partition, before closing the file (i've updated one
of the unit tests to double-check the call). In the partitioning.py
caller we execute a sync call too.
Since it does seem unlikely the "-s" option of kpartx is not working,
I've removed the udev settle work-around too.

Partial-Bug: #1698337
Debian Stretch released as stable recently, and the init system is
less tightly specified in the base dependencies (for some info, see
[1]). It seems, probably unintentionally, that in the previous
release systemd-sysv was brought in by debootstrap, but that is no
longer happening.
Add systemd as an early dependency of debian-minimal.
Remove the package-installs.yaml as that happens too late (other
things need to know the init system to write out service files, etc
and probe for systemd utils before package-installs). As mentioned, I
do not believe the "only install systemd on testing" idea was actually
working here, because it was being brought in during the initial
debootstrap.

This adds a devstack-inspired output filter to standardise
timestamping.
Currently, python tools timestamp always (timestamp setup in
logging_config.py) but all the surrounding bash does not.
We have extra timestamps added in run_functests.sh for our own
purposes to get the bash timestamps; but this ends up giving us
double-timestamps for the python bits. Additionally, callers such as
nodepool capture our output and put their own timestamps on it, and
again have the double-timestamps.
This uses a lightly modified outfilter.py from devstack to standardise
this.
All output is run through this filter, which will timestamp it. I
have removed the places where we double-timestamp -- logging_config.py
and the prefix in dib-run-parts.
An env option is added to turn timestamps off completely (does not
seem worth taking up a command-line option for). For callers like
nodepool, they can set this and will just have their own timestamps as
they collect the lines.
Since all logging is going through outfilter, it's easy to add a
--logfile option. I think this will be quite handy; personally I'm
always redirecting dib runs to files for debugging.
I've also added a "quiet" option. I think this could be useful in
run_tests.sh if we were to start logging the output of each test to
individual files. This would be much easier to deal with than the
very large log files we get (especially if we wanted to turn on
parallel running...)

Using the newly exposed variables from the prior change, install the

Change-Id: I0918e8df8797d6dbabf7af618989ab7f79ee9580
Currently we only export "image-block-device" which is the loopback
device (/dev/loopX) for the underlying image. This is the device we
install grub to (from inside the chroot ...)
This is ok for x86, but is insufficient for some platforms like PPC
which have a separate boot partition. They do not want to install to
the loop device, but do things like dd special ELF files into special
boot partitions.
The first problem seems to be that in level1/partitioning.py we have a
whole bunch of different paths that either call partprobe on the loop
device, or kpartx. We have _all_part_devices_exist() that gates the
kpartx for unknown reasons. We have detach_loopback() that does not
seem to remove losetup created devices. I don't think this does
cleanup if it uses kpartx correctly. It is extremley unclear what's
going to be mapped where.
This moves to us *only* using kpartx to map the partitions of the loop
device. We will *not* call partprobe and create the /dev/loopXpN
devices and will only have the devicemapper nodes kpartx creates.
This seems to be best. Cleanup happens inside partitioning.py.
practice. Deeper thinking about this, and more cleanup of the
variables will be welcome.
This adds "image-block-devices" (note the extra "s") which exports all
the block devices with name and path. This is in a string format that
can be eval'd to an array (you can't export arrays).
This is then used in a follow-on

Currently we pass a reference to a global "rollback" list to create()
to keep rollback functions. Other nodes don't need to know about
global rollback state, and by passing by reference we're giving them
the chance to mess it up for everyone else.
Add a "add_rollback()" function in NodeBase for create() calls to
register rollback calls within themselves. As they hit rollback
points they can add a new entry. lambda v arguments is much of a
muchness -- but this is similar to the standard atexit() call so with
go with that pattern. A new "rollback()" call is added that the
driver will invoke on each node as it works its way backwards in case
of failure.
On error, nodes will have rollback() called in reverse order (which
then calls registered rollbacks in reverse order).

Keep track of the mount-point ordering in a state variable, rather
than a global. This path is tested by existing unit tests.
Note a prior change inserted the MountNode objects directly into a
list in self.state, which makes sorting quite easy as it can just
implement __lt__. Unfortunately we still json dump the state, and
thus we can't have aribtrary objects in it (future work may be to
check keys inserted into the status object...). So we have to do a

With I468dbf5134947629f125504513703d6f2cdace59 each node has a
reference to the global state object. This means it gets pickled into
the node-list, which is loaded for later calls. There is no need to
reload the state.json it and pass it for later cmd_* calls, as the
nodes can see it via the unpickled self.state
Change-Id: I9e2f8910f17599d92ee33e7df8e36d8ed4d44575
Making the global state reference a defined part of the node makes
some parts of the block device processing easier and removes the need
for other global values.
The state is passed to PluginNodeBase.__init__() and expected to be
passed into all nodes as they are created. NodeBase.__init__() is
updated with the new paramater 'state'.
The parameter is removed from the create() call as nodes can simply
reference it at any point as "self.state".
This is similar to 1cdc8b20373c5d582ea928cfd7334469ff36dbce, except it
is based on I68840594a34af28d41d9522addcfd830bd203b97 which loads the
node-list from pickled state for later cmd_* calls. Thus we only
build the state *once*, at cmd_create() time as we build the node
list.
Change-Id: I468dbf5134947629f125504513703d6f2cdace59
Currently the later cmd_* calls -- umount, cleanup, delete -- all
recreate the node graph by parsing the config file using
create_graph()
There is some need, however, to have a sense of global state when
building the node list. The problem is, this is a one time operation
-- we do not want to rebuild that state for these later calls (see the
"loaded" checks in proposed
Ic3b805f9258128d5233b21ff25579c03487c7fcc).
An insight here seems to be that these cmd_* calls do not actually
want to re-parse the configuration file and rebuild the node list;
they just want to walk the node list in reverse with the state as
provided after cmd_create().
So, rather than re-creating the node list, we might as well just
pickle it, save it to disk along side the state dictionary dump and
reload it for cmd_*.
After this, I think we can safely have PluginBase.__init__() be passed
the state. We will now know that this will only be called once,
during initial creation.
Change-Id: I68840594a34af28d41d9522addcfd830bd203b97
You can't pickle a static method reference which complicates being
able to save the node graph when the "rollback" call-back wants to
hold references to these functions. The outer module (localoop.py) is
small anyway, so from an organisation point of view the difference is
minimal. Since these are really only called with parameters from the
containing class, they could be class methods with no parameters, at
the small expense of having to fiddle the mbr test-case a bit.

This is code motion with some small changes to make follow-on's

test_blockdevice_mbr.py is moved alongside the other tests. It is
modified slightly to use the standard base class and remove a lot of
repeated test setup; a fixture is used for the tempdir (so it doesn't
have to be torn-down, and is removed properly on error) and the partx
args are moved into the setUp() so each test doesn't have to create
it. No functional change. renamed test_mbr.py for shortness.
test_blockdevice_utils.py is merged with existing test_utils.py. No
change to the tests.
test_blockdevice.py is removed. It isn't doing anything currently; to
work it will need to take an approach based more on mocking of calls
that require elevated permissions. It's in history if we need it.

Currently we keep a global list of mount-points defined in the
configuration and automatically setup dependencies between mount nodes
based on their global "mount order" (i.e. higher directories mount
first).
The current method for achieving this is roughly to add the mount
points to a dictionary indexed my mount-point, then at "get_edge()"
call build the sorted list ... unless it has already been built
because this gets called for every node.
It seems much simpler to simply keep a sorted list of the
MountPointNode objects as we add them. We don't need to implement a
sorting algorithm then, we can just use sort() and implement __lt__
for the nodes.
I believe the existing mount-order unit testing is sufficient; I'm
struggling to find a valid configuration where the mount-order is
*not* correctly specified in the configuration graph.

A couple of things going on, but I think it makes sense to do them
atomically.
The NodeBase.create() argument "results" is the global state
dictionary that will be saved to "state.json", and re-loaded in later
phases and passed to them as the argument "state". So for
consistency, call this argument "state" (this fits with the change out
to start building the state dictionary earlier in the
PluginBase.__init__() calls).
Since the "state" is a pretty important part of how everything works,
move it into a separate object. This is treated as essentially a
singleton. It bundles it nicely together for some added
documentation [1].
We move instantiation of this object out of the generic
BlockDevice.__init__() call and into the actual cmd_* drivers. This
is because there's two distinct instantiation operations -- creating a
new state (during cmd_create) and loading an existing state (other
cmd_*). This is also safer -- since we know the cmd_* arguments are
looking for an existing state.json, we will fail if it somehow goes
missing.
To more fully unit test this, some testing plugins and new
entry-points are added. These add known state values which we check
for. These should be a good basis for further tests.
[1] as noted, we could probably do some fun things in the future like
make this implement a dictionary and have some saftey features like
r/o keys.

This was suggested in a review comment in

The new file plugin.py is the place to start with this change. The
abstract base classes PluginBase and NodeBase are heavily documented.
NodeBase essentially replaces Digraph.Node
The changes in level?/*.py make no functional changes, but are just
refactoring to implement the plugin and node classes consistently.
Additionally we have added asserts during parsing & generation to
ensure plugins are implemented PluginBase, and get_nodes() is always
returning NodeBase objects for the graph.
Change-Id: Ie648e9224749491260dea65d7e8b8151a6824b9c
This switches the code to use networkx for the digraph implementation.
Note that the old implementation specifically isn't removed in this
change -- for review clarity. It will be replaced by a base class
that defines things properly to the API described below.
Plugins return a node object with three functions
get_name() : return the unique name of this node
get_nodes() : return a list of nodes for insertion into the graph.
Usually this is just "self". Some special things like partitioning
add extra nodes at this point, however.
get_edges() : return a tuple of two lists; edges_from and edges_to
As you would expect the first is a list of node names that points to
us, and the second is a list of node names we point to. Usually
this is only populated as ([self.base],[]) -- i.e. our "base" node
points to us. Some plugins, such as mounting, create links both to
and from themselves, however.
Plugins have been updated, some test cases added (error cases
specifically)
Change-Id: Ic5a61365ef0132476b11bdbf1dd96885e91c3cb6
This moves to a more generic config parser that doesn't have plugins
parsing part of the tree.
I understand why it ended up that way; we have "partitions" key which
has special semantics compared to others keys and there was a desire
to keep it isolated from core tree->graph code. But this isn't really
isolated; you have to reverse-engineer several module-crossing
boundaries, extras classes and repetitive recursive functions.
Ultimately, plugins should have access to the node graph, but not
participate in configuration parsing. This way we ensure that plugins
can't invent new methods of configuration parsing.
Note: unit tests produce the same tree -> graph conversion as the old
method. i.e. this is not intended to have a functional change.

This is a follow-on to 57ef187632.
There's two things going on here; DIB_MANIFEST_IMAGE_DIR is *outside*
the chroot on the build host. We copy the files here for posterity, I
guess. MANIFEST_IMAGE_PATH is *inside* the chroot and are the files
we want to ensure are locked to root.
The prior change modified the permissions on DIB_MANIFEST_IMAGE_DIR.
So the first time you build, it works -- then the second time,
assuming you're using the same output filename, it hits the root-owned
manifest directories and causes a build failure.
I have built with this and checked that the manifest files in the
image are locked to root:

It seems that the redhat nodepool job is quite reliably geting a

red-herring, since the logs are full of

I think in our recent de-puppetisation of hosts, something might have
changed that is setting LC_ALL=C.UTF-8 for the jenkins user, at least
on Ubuntu. This is a problem for centos, as it doesn't have C.UTF-8
locale. I then think using the invalid locale is what leads the the

calculate runtimes.

Instead of passing in all the parameters separately this patch

Recent changes in project-config have shown that we leave the system
in an inconsistent state when installing from source. On fedora, we
will have installed the python2 packages, but then used $DIB_PYTHON to
install python3 pip from source!
This tries to clarify the situation. As described in the document,
with package installs, we just install the $DIB_PYTHON packaged
versions.
Source installs want to take over the global namespace. This is the
price you pay for running the latest versions outside package managers
:) The only sane thing seems to be for us to normalise python2 &
python3 versions of pip, setuptools and virtualenv and then hacking
things such that "/usr/bin/pip" and "/usr/bin/virtalenv" remain
defaulted to python2 versions.
Documentation is added

The current output for package-installs-v2 is inscrutable [1]
The problem starts with process_output() which is not capturing
stderr. This means that any stderr output is dislocated from any
stdout output around it. This is *really* confusing as you get a
bunch of seemingly meaningless stderr output from any calls before you
see any stdout (e.g. in [1] you can see random yum error output that
should have been with the yum call)). The simplest thing to do is to
redirect stderr to stdout which keeps everything in sync.
This causes a slight problem, however, because pkg-map outputs both
status information and errors on stderr. To work around this but
maintain compatibility, we add a "--prefix" argument that prepends
mapped packages from pkg-map with a value we can match on. The
existing status/debug output from pkg-map is low-value; modify the
call so that it will be traced only at higher debug levels (e.g. -x
-x).
The current loop is also calling pkg-map for every package in every
element (this is why in [1] the same message is repeated over and
over). This is unnecessary; it only needs to pkg-map once for each
element, giving the package list as the arguments. Create package
lists by element and pass those to pkg-map.
As a cleanup, there is no point in printing e.output if the
process_output fails for the install because we are already tracing
it; i.e. the output, even for failures, is already in the logs.
Printing it again just duplicates the output.
[2] is an extract showing what I feel is a much more understandable
log output for a fairly complex install.

The dib-run-parts element was copying our internal version of
dib-run-parts into /usr/local/bin to be used running scripts inside
the target chroot. However, it never cleaned up after itself. This
means all images were left with an unmanaged local install of
dib-run-parts.
This copies dib-run-parts into the hooks directory of the chroot and
runs it from there. It is cleaned up automatically on the exit path.
The dib-run-parts element is no longer required and it has been
removed from all dependencies. It is left with a deprecation notice
in the README. For compatability we convert it to simply install
dib-utils.
Codesearch shows no users depending on this unintentional implicit
install. Note os-refresh-config depends on dib-utils and thus will
have an explicitly installed version.

It was an oversight during v2 development for dib to start providing
dib-run-parts. The intention was for dib to use a vendored
dib-run-parts directly from $_LIB and have no dependencies on
dib-utils at all. By exporting dib-run-parts, we created an
unintentional conflict with the dib-utils package which provides the
same script.
Tools that depend on dib-utils are unaffected by this
(os-refresh-config).
The only tool that installs diskimage-builder and then assumes
dib-run-parts is available in the path is instack. I have proposed

We somewhat discussed skipping qcow2 generation previously in
I9372e195913798a851c96e62eee89029e067baa1. As recent issues with PPC
testing have shown, we are not actually testing the "vm" element and
hence the bootloader path in the functional tests.
I don't think we need to test this on every element; it overlaps
somewhat with the testing done by the nodepool jobs which build full
images and boot them. I also didn't want to introduce a separate run
for this. Thus it seems valuable to at least have one element
enhanced to do this installation and conversion in our default tests
for basic sanity.
This disables qcow generation by default, as per the other change, but
allows an element to drop a file that will override the output
formats. The Xenial element is modified to produce a qcow2 using
this, and also introduces a dependency on the "vm" element so it tries
to install the bootloader.
We now exit if the .qcow2 fails to build as well.

Currently there is no description of dependencies in the generated
documentation of the elements: therefore a user of an element does not
know which other elements are automatically included and e.g. which
configuration options are available. In addition there are some
copy&pastes of parts of the README.rst scattered thought different
Ubuntu and Debian specific elements.
This patch adds a semi-automatic generation of dependency information
of all elements. Nevertheless these are not automatically included.
The author of the element's README.rst can decide if and where the
dependency information should appear and can use the descriptor
.. element_deps::
for this.
This patch adds the dependency information for some Debian and
Ubuntu patches - and creates the base for later removing the
duplicated parts.
A call is added to element_dependencies._find_all_elements() to
populate reverse dependencies for Element objects.

expand_dependencies() was a public interface so we should try and
preserve backwards compat. However, since the interface is really
broken, add a new exported function "get_elements" that instack can
switch to. This returns the canonical list of elements without
duplicates, and gives the path to each element too.
This highlighted that the unit tests were really a bit wrong. They're
testing inner functions when we have an "API" in the get_elements()
function. Convert all unit-tests to use this function instead. Since
this is a library call, convert the sys.exit() calls to raised
exceptions.
Refactor the variable output into a separate function so we can do a
sanity check on it.
The added flake8 ignores are for the "over-indented for ... indent"
which happens a lot with these new longer lines. Most other projects
ignore them.

Move dib-run-parts from dib-utils into diskimage-builder directly.
For calling outside the chroot, we provide a standard entry-point
script. However, as noted in the warning comment, the underlying
script is still copied directly into the chroot by the dib-run-parts
element. I believe this to be the KISS approach.
This removes the dependency on dib-utils. We have discussed this
previously and nobody seemed to think retiring dib-utils was going to

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__.

These new variables are a list of elements chosen for the build along
with their full paths. For Python elements, IMAGE_ELEMENT_YAML is a
YAML formatted list that can be easily parsed. For bash elements,
"get_image_element_array" will produce an associative-array of the
same (working around lack of array export in Bash).
This list is intended for consumption of elements who need to copy
files from other elements, such as pkg-map and svc-map. As discussed
in I2a29861c67de2d25c595cb35d850e92807d26ac6, this list has already
been pruned and had overrides processed, so it is safe to simply walk
over this list with no further processing.
Since we're presenting the element list in a couple of different ways,
we combine it all into the element-info script. It will output an
eval-able string that declares the appropriate variables.
I've added some inline documentation so they still appear in grep.
The documentation is updated with examples, and moved to a more
appropriate location as a sub-section of the element sytle guide.
To test this out, use the associative-array in generate_hooks, where
we can now find the element's directory without searching.

This is a re-factor of element_dependencies to achieve two things --
centralising override policy and storing path names.
Firstly we want to make the override policy for elements completely
explicit. Currently, elements that wish to copy parts of other
elements walk ELEMENTS_PATH themselves and look for elements in
IMAGE_ELEMENT. How they handle duplicate elements can differ, leading
to inconsistent behaviour.
We introduce logic in element-info to find elements in each of the
directories in ELEMENT_PATHS in *reverse* order -- that is to say,
earlier entries in the paths will overwrite later ones.
For example
ELEMENT_PATHS=foo:bar:baz
will mean that "foo/element" will override "baz/element", since "foo"
is first. This should be sane to anyone familiar with $PATH.
Documentation is clarified around this point and a test-case is added.
The second thing is that we want to keep the complete path of the
elements we have chosen. We want the aforementioned elements that
walk the element list to use these canonical paths to pickup files;
this way they don't need to make local decisions about element
overrides, but can simply iterate a list and copy/merge files if they
exist.
A follow-on change (I7092e1845942f249175933d67ab121188f3511fd) will
expose this data in a separate variable that can be parsed by elements
(a further follow-on I0a64b45e9f2cfa28e84b2859d76b065a6c4590f0
modifies the elements to use this information). Thus this does not
change the status-quo -- elements that are walking ELEMENTS_PATH
themselves and can/will continue doing that.

I got quite confused what this was trying to tell me at first. It's
saying that you requested an element but another element already
provides that element, so we don't know which one to choose.
To help clarify the situation to the user, keep track of what is
providing elements so we can describe where the conflict came from.

Use standard logging module for output. Add some basic testing of
error messages to the unit-tests. Use the logging_config module to
setup the logging for interactive use.
Change-Id: Ia23722a7bd00aba336118edb155356a3b3ef6926
This adds some fixtures to ensure the log output is what we expect,
along with ensuring we test the operation of the debug environment
variables.

This adds a common usable logging configuration for DIB, that
can be used by different python tools or elements.
This change is a factored out patch from the block device
refactoring.

This repo is not translated by default, so no need to have old
translation files in here that can be regenerated any time.
Remove also the English translation since English is the source
language, there's no need to have an extra translation at all.

Deprecated the `--expand-dependencies` flag from `element-info` usage.
The flag was required and not optional. We can rely on argparse to exit non-0
when the required positional argument is not provided.

A sanity check that cache-url does the right thing when presented
with the appropriate curl return codes. This change brings in the
test code for scripts from tripleo-image-elements, which needs to
be factored out into a place both projects can use it.
I'm stubbing out curl so we don't have a dep on curl in our unit
tests, and because I've seen some strange behavior out of curl in
the gate that caused random failures in this test.

The phrase is no longer needed as of August 23, 2000 with Nicaragua's
joining of the Berne Convention.
Additionally, in at least one instance,
elements/cache-url/bin/cache-url, its existence in the file between
Copyright lines is just weird and feels misleading, even though it is
not.
Remove all of the lines, because sanity.

To ensure that we have the list of provided elements from the
command line before looking up dependencies, use a deque and
popleft() to take the elements on a first-in/first-out basis.

An element can define a list of elements provided by itself. This allows
using an alternative element and keeping element dependencies at the
same time. This will be needed for example for mariadb element which will be
an alternative to mysql element - mysql dependency can be kept everywhere
but user can choose mariadb explicitly as a replacement by putting "mysql"
into "element-provides" file.

This commit refactors the python code in diskimage_builder slightly. This is
in preparation for a larger review that adds more functionality to the python
code, namely the ability to apply elements to the current system as opposed to
a chroot. Further, the refactorings can stand on their own for better clarity.
They include:
- renaming elements.py to element_dependencies.py. Adds clarity about the
purpose of this module.
- updating other code for this rename.
- move tests into a tests submodule.

Using ELEMENTS_DIR env variable, you can specify multiple dirs containint your elements.
It must be a ":" separated elements list.
When an element is seen in one of those lists, it will be chosen and will continue with the next element.

bin/element-info accesses it's library via a symlink:
bin/diskimage_builder -> diskimage_builder
This causes the relative path in elements.py to be
incorrect.
element-info silently fails in this situation, because
it allows missing 'element-deps' files, so that these files
may be optional.
This change causes element-info to fail explicitly if $ELEMENTS_DIR
is not set, as it now is when called by diskimage-create, and
adds tests reflecting this behavior.
