The call to fstrim in disk-image-create is currently useless, because
at the time this is called, the file systems were already umounted by
the block device layer.
The current implementation of the block-device mount plugin does not
call fstrim at all: resulting in larger image sizes.
This patch removes the useless fstrim call from the disk-image-create
script and moves this into the block-device mount.py.
The resulting image might be much smaller. Example: Ubuntu Xenial
with some elements; once with and once without this patch:
-rw-r--r-- 1 dib dib 475661824 Sep 16 06:43 ubuntu-xenial-without-fstrim.qcow2

This reverts commit a47ff0dd4a.
Since this merged, a global-requirements pin to keep networkx <2.0 has
also merged. The plan is:
1. revert our 2.0 support and
1a. take the <2.0 pin from global requirements
2. figure out how to use constraints properly in our testing
3. restore this, with a depends-on for a 2.0 bump in requirements
(which will self-test, see 3.)
4. when other projects are ready for a global 2.0 bump, merge
in a controlled fashion
This reverts the 2.0 support, and adds the pin for networkx <2.0

A small update was made to 4.4.0-96.119 that dropped the
initramfs-tools dependency from the kernel [1]. This had the
unfortunate affect of removing the initramfs from ubuntu-minimal and
making it unbootable, since we specify the root device via LABEL=.
Add the package explicitly alongside the kernel.
Also, small fix to pass unit tests

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).

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.

In preparation for promoting the openSUSE jobs to voting ones we should

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

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.

fedora/centos-minimal don't obey DIB_DISTRIBUTION_MIRROR currently. I

with repo files to use during the install.
This introduces setup-gate-mirrors.sh which is intended to setup

on each CI node.

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.

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.

Closes-Bug: #1698337
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
ppc bootloader to the boot partition, not the underlying loopback
device.
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.

As we add file-systems, add them to global state and check the labels
are uniqiue. Add a unit test and remove the old global value.
Bonus fixup to the length check, and a test for that too.

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.

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.

The supported ppc ${ARCH} is "ppc64el" (at least in the gate testing
...) so move the file to that, so gets picked up by
block_device_create_config_file
