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.
Update some documentation to explain what's going on

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
(I0918e8df8797d6dbabf7af618989ab7f79ee9580) to pick the right
partition on PPC.

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

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
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.

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

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

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.

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.

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

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.

The args agument was only used to find the symbol for the getval
command. Have the command pass the symbol to find in directly. We
can therefore remove the args paramater to the BlockDevice() creation.

Move argument parsing to subparsers, rather than positional arguments.
This better reflects the tool's role as a driver and allows

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

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.

The original approach was to pass each and every command
line parameter to the block device. While the block device
functionality gets extended, this is not any longer practical.
Instead of passing in all the parameters separately this patch
collects these in a YAML file that is passed in to the block device
layer.

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

Currently we install pip/virtualenv with "/usr/local/bin/dib-python".
This means that every time you create a virtualenv, the python
interpreter inside it is called "dib-python" which is confusing.
Add an env var DIB_PYTHON that points directly the to interpreter
available during build, for use when running scripts.

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
Ibfe972208df40fa092b11b5419043524c903f1b4 to modify that to use our
internal version.

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.

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.
