18a0d970fa Move ironic-agent test to fedora-minimal
I'm uncertain as to why this is using the "fedora" element for testing
... but it requires downloading the fedora .qcow on every test which
has shown to be unreliable.  An easy thing to do is to switch it to
fedora-minimal; that will only involve downloads from local mirrors in
the gate.

Add redhat-rpm-config for minimal.  I admit I have not fully gone
through why this is not pulled in.  It's been an issue since
I459f2203fa145049dda185da952813118193d573 and there's all sorts of
bugs.

649f0b66d9 Start at using CI mirrors for fedora/centos
fedora/centos-minimal don't obey DIB_DISTRIBUTION_MIRROR currently.  I
don't really want them too -- we want to be able to separate the
mirrors used during the build process from those embedded into the
final image.  Add DIB_YUM_MINIMAL_BOOTSTRAP_REPOS which is a directory
with repo files to use during the install.

This introduces setup-gate-mirrors.sh which is intended to setup
repo/sources/whatever files in the openstack gate that point to the
local region mirror.  It pulls the info from the mirror_info.sh script
on each CI node.

The openstack-ci-mirrors element is updated to export these variables.
elements are updated to depend on it.  Tests are restored

f0b70211c6 Use local mirror for ubuntu-minimal jobs
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

0d37351031 Move apt-sources to ubuntu-minimal / move debian to skip list
The gate is currently extremley unstable, and these two issues are
causing most of the problems.  We need to commit them atomically so we
can get anything moving again

---

The gate is very unstable downloading the ubuntu tarballs from
upstream at the moment.  Move this to ubuntu-minimal which, in a later
change will source files from our local mirror.

We need a caching mechanism for these large files to avoid this
instability.  This is future work for the various image-based jobs.

---

Move debian to default skip lists

I don't know if it's mirrors being worked hard for the Stretch
release, but this is constantly failing the gate.  I will move this to
the -nv extras job

I am working on having the voting job use local mirrors for
everything.  Unfortunately debian infra mirrors don't have stretch yet
and we need to do some fiddling to get "stable" available.  Once we
have all this, we can consider making it voting again.

5d5fa06e5c Sync after writing partition table
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.

a0f747932d Install systemd earlier for Stretch
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.

Update some documentation to explain what's going on

250aeb5d21 Fix mkfs failure when loop device is not ready
There was a race in diskimage-builder where the mkfs call after a
kpartx -avs for the loop device would fail because the device was
not yet ready.  This adds a udevadm settle call after the kpartx
to make sure the udev event queue has cleared.

6c394f5746 Pass all blockdevices to bootloader
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
(I0918e8df8797d6dbabf7af618989ab7f79ee9580) to pick the right
partition on PPC.

1d1e4ccb3e Move rollback into NodeBase object
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).

A unit test is added to test rollback behaviour

09dee46579 Move global mount tracking into state
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
bit of wrangling with tuple lists and comparision functions here, but
it's not too bad.

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.

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:

"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.
