b708918b85 Remove 'state' argument from later cmd_* calls
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

824a9e91c4 Add state to NodeBase class
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.

e82e0097a9 Use picked nodes for later cmd_* calls
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.

9a8b135267 Don't make image & loopdev functions static
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.

cdb1a95be1 Move "functional" unit tests under block-device
This is code motion with some small changes to make follow-on's
easier.

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.

4253cab773 Make BlockDeviceState implement a dict
While plugins treat the state as just a dictionary, it's nice for the
driver functions to keep state related functions encapsulated in the
state object singleton.  Wrap the internal state dictionary so we can
pass the BlockDeviceState directly without dereferencing.

35a1e7bee9 Refactor mount-point sorting
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.

b85de3cd9e Add state object, rename "results", add unit tests
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.

f314df12c3 Refactor: use lazy logging
As described in pep282 [1], the variable part of a log message
should be passed in via parameter.  In this case the parameters
are evaluated only when they need to be.

This patch fixes (unifies) this for DIB.

A check using pylint was added that this kind of passing parameters to
the logging subsystem is enforced in future.  As a blueprint a similar
(stripped-down) approach from cinder [2] was used.

This was suggested in a review comment in
I8a5d62a076a5a50597f2f1df3a8615afba6dadb2.  It works out quite nicely
because the BlockDevice() driver now doesn't need to know anything
about stevedore or plugins, and just works on the node list.  It also
simplifies the unit testing by not having to call create_graph through
a BlockDevice object.

deb832d685 Create and use plugin/node abstract classes
This completes the transitions started in
Ic5a61365ef0132476b11bdbf1dd96885e91c3cb6

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.

75817ef205 Use networkx for digraph
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)

00da1982ce Add a more generic tree->graph parser
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.

f1369a1add Set manifest permissions in the image
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:

b91207ae47 Remove _config_error thrower
"log and throw" is arguably an anti-pattern; the error message either
bubles-up into the exception, or the handler figures it out.  We have
an example where this logs, and then the handler in blockdevice.py
catches it and logs it again.

Less layers is better; just raise the exception, and use log.exception
to get tracebacks where handled.

0d8c4270c0 exec_sudo: check cmd for str, log output and raise exception
To avoid any confusion, commands passed to exec_sudo() should be a
list of "str"s.  Log a message if we see unicode issues.

This also adds a debug trace of all output.  stderr is captured.

This is modified to raise CalledProcessError on failure, like
check_call().  Calls that are ok to fail will need to explicitly catch
and ignore this.

The two calls that we expect to fail are wrapped

We wish to try rolling back if one of these command raises an
exception.  Modify the create handler to initiate rollback on all
exceptions.

91ba21dd6c Set LC_ALL in disk-image-create
It seems that the redhat nodepool job is quite reliably geting a
"floating point" error during centos image build.  This happens after
03-yum-cleanup which is pruning the locales.  This might be a
red-herring, since the logs are full of

  /bin/bash: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8)

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
floating-point error when doing some maths in dib-run-parts to
calculate runtimes.

We are currently overriding LANG, but we really want LC_ALL to ensure
this applies globally.

79d4113cbe pip-and-virtualenv : install python2 & 3, and default to 2
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

f068e6aa6e Fix package-installs-v2 output
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.

6802cf7100 Run dib-run-parts out of /tmp
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.

fd424757a6 Don't provide dib-run-parts
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
Ibfe972208df40fa092b11b5419043524c903f1b4 to modify that to use our
internal version.

4d4417c9a6 Use correct Ubuntu distro url on non-x86 arches
diskimage-builder usually provides defaults that work out of the box.
One default that does not work outside of x86 land is Ubuntu distro
mirror url. Considering there are only two valid default options, we can
automatically choose a better default.

This patch changes behavior only for architectures known to be using
http://ports.ubuntu.com/ubuntu-ports. All others still would use
http://archive.ubuntu.com/ubuntu as default. It provides some guarantee
that we do not introduce a regression.

76ae374413 functests: skip qcow2 generically but add specific test
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.

fdd2c4b236 Semi-automatic doc generation of element dependency
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.

19f13958f7 Handle blank lines in element-deps
When merging feature/v2 we have re-enabled the centos-minimal test
which has a blank line in the element-deps.  The modified get_elements
functions added in If97bcd21e45de1b5ed91023fdc441a4617051a6b were not
handling this.

Fixing this, we can extract this into some common code for
element-deps and element-provides.

Also, I noticed while debugging that the element list is an iterator
from reverse(), so printing it doesn't help.  Fix up the debug output.

5da7574aee Add get_elements; preserve backwards compat for expand_dependencies
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.

This is an alternative proposal to

Because we're still fundamentally a python program calling a
shell-script, there's some oddities like not having the virtualenv
bin/ in the $PATH if we call disk-image-create directly.

We can detect this, however, and activate the virtualenv before we
fork the disk-image-create shell script so everything "just works".

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
be an issue.

This also updates the documentation to not mention dib-utils, or using
disk-image-create via $PATH setup, but rather gives instructions on
installing from pip with a virtualenv.

7446c32197 Move diskimage-image-create to an entry point
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 :)

97c01e48ed Move elements & lib relative to diskimage_builder package
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__.

3d48a528c1 Refactor: block-device handling (local loop)
Block device handling can be somewhat complex - especially
when taking things like md, lvm or encryption into account.

This patch factors out the creation and deletion of the local
loop image device handling into a python library.

The main propose of this patch is to implement the needed
infrastructure.  Based on this, more advanced functions can be added.
Example: (advanced) partitioning, LVM, handling different boot
scenarios (BIOS, UEFI, ...), possibility of handling multiple images
(local loop image, iSCSI, physical hard disk, ...), handling of
different filesystems for different partitions / LVs.

37a53354ec Add IMAGE_ELEMENT_YAML and get_image_element_array
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.

274be6de55 Making element overriding explicit
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.

308eee2827 Use multiple locations for elements dir.
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.

6cfea30246 Prevent silent failure of element-info:
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.

c3ee071d73 Make it possible for openstack-CI to run tests
Per http://wiki.openstack.org/ProjectTestingInterface we enable all
of the commands except build_sphinx because we do not have any sphinx
documentation as of yet. Includes babel support though there are no
properly internationalized strings just yet.

c8c33e3bb1 Add a simple implementation of element dependency
This adds a new optional file to the root of elements. The
file lists dependencies which will be added to the list
requested by the user during disk image creation.
