c1985ea772 Add dib-lint exclusions
This patch adds exclusions for the indentation and newline
rules in dib-lint.  The indentation exclusion is needed for
files using heredoc and wanting to preserve indentation.
The newline exclusion is added here for consisently treating
all dib-lint rules the same.

541a4b2270 Add global exclusions to dib-lint
This will be useful for adopting dib-lint in other projects, in
particular tripleo-image-elements.  It allows some dib-lint rules
to be used even if the project can't pass all of the checks.  The
failing checks can then be fixed one at a time and removed from the
exclusions list.

For consistency, this change reads the new exclusions from tox.ini
in the same way as flake8.  To use the exclusion mechanism, the
the following section can be added to tox.ini:

  [dib-lint]
  ignore = sete setu setpipefail

bccffc8bfd Refactor code to select boot kernel
The script to find best kernel from image (used by vm
and baremetal element) is duplicated and is not in sync
with each other. Moving the code to img-functions as a
function will reduce duplicated code and make it reusable
in future.

Since img-functions is not accessible in chroot env,
kernel selection is being moved from finalise.d to
cleanup.d in the vm element.

e824b43cbd Factor out error behavior in dib-lint
Currently when dib-lint finds a problem it does something like:

 echo "ERROR: Problem found"
 rc=1

This is repetitive and error-prone since it's easy to forget to set
rc to actually fail the check.  This change makes those two steps
a single function call.

825b1964bb Allow excluding tests from certain files
There are certain scripts (such as the ramdisk init script) that
need to ignore linting rules for one reason or another.  This adds
support for exclusions via a comment in the file like:

"# dib-lint: disable=executable sete"

There should be no ", but I need those to prevent git from treating
that as a comment.  This syntax is similar to the pylint exclusion
mechanism.

Exclusion support is added to the executable check, but not
the alphabetical ordering one because I can't imagine a reason we
would need to disable that, and I don't know that comments are
supported in those files anyway.

save_image is used to copy kernel and ramdisks out of the image, which

for the main image itself, the temp copy is never kept, so use mv
  rather than cp and avoid the excess IO.

ea555476cc Make max-online-resize an option.
In fb246a02eb we introduced an
ext4 option to allow root filesystems to be resized up to 1PB.
This appears to cause an ext4 resize2fs bug in some images.

When the issue occurs an image will hit a kernel bug when
cloud-init runs the resize2fs command during first boot:

  kernel BUG at fs/ext4/resize.c:409!

In this commit we add a new option for max-online-resize
which can be used if a really large root partition is
desirable.

The root cause of all this is really a design problem in
DIB/TripleO at the moment in that we shouldn't have to worry about the
max size of the root file system when creating our images.  Ideally we'd
just mkfs on the root file system itself. Much more efficient,
avoids this problem altogether...

I think the best thing to do today to avoid this is make setting
max-online-resize an option in DIB. This will allow us to stick
to the (well tested) ext4 defaults for most cases, and if someone has
need for a large root filesystem they can easily bump the setting. This
may be temporary until we either fix the design... or the ext4 fix is
released.

size the root filesystem does not leave enough room for grub which is

d5b30d126e Increase the size heuristic for images
Occasionally cloud-init fails to resize the disk on first boot, this is
occuring because the filesystem has only 10% free. Nudging the disk size
up a bit more should give us a little more headroom so this is less
likely to occur.

I havn't been able to find out what value ensures we wont hit this
problem but I can say for sure this fixes all casses of the problem I
have seen.

--help will tell you about the cli parameters.  Preserves the old
behavior as well where if DIB_IMAGE_SIZE is set in your environment, it
will be honored.

dee69b1810 Python code refactorings.
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.

dbfca7a816 Combine compress and save image into one function
When compressing an image, this is done in the same dir where the raw
image resides, doubling the amount of space needed (scarce when
using tmpfs), and then it's moved to the .cache folder in disk.

Combining these two functions, we reduce the amount of space needed
in the tmpfs partition (when in use), and the compressed image is
created directly on the .cache folder disk, so there is no need to
move the compressed image after the process into disk.

- Ensures /sbin and friends are in $PATH when invoked (without this,
  various sudo invocations fail in exciting ways).
- Use dib-run-parts in lib/common-functions instead of run-parts
  (neither SLES nor openSUSE ship run-parts).
- Ensure dib-run-parts doesn't descend into subdirectories (same
  behaviour as run-parts).
- Move dib-run-parts from root.d to bin (cleaner, consistent with
  other elements with separate bin scripts).
- Tested by building Ubuntu image on openSUSE 12.3.
- Note: this doesn't add support for creating SUSE images, it just
  lets you run disk-image-create on SUSE-based distros.

b2f1d4e2af Document an interface for offline operation.
Complex image builds can download hundreds of MB of data from the
internet with many separate lookups. It would be nice to allow users
to ask for a fast build where those lookups are entirely avoided,
using locally cached resources (where possible). This new interface
allows users to signal to elements that they wish to operate without
updating cached resources, which will in turn allow us to avoid
checking for stale data at all.

As part of this I've also documented where we cache data, so that
things like the ccache cache dir and image cache files are not a
surprise to users.

8d1ce9c0c3 Build ramdisks in an image chroot.
Ramdisks are now built inside a chroot which is built by the normal
image build process. Doing so improves our independence of the
precise state of the build host.

This fixes bug 1194055.

9983245249 Honor $DIB_IMAGE_SIZE.
The recent change to use loopdev instead of nbd stopped
honoring the DIB_IMAGE_SIZE setting.

This change adds it back, by resizing the image to
DIB_IMAGE_SIZE GB, if specified. If unspecified, it resizes
the image to (actual usage + 20%), as it did before this change.

20661e8d80 Retry losetup -d for up to 10 seconds.
When partition tables are added to loopback devices, this can set off a
chain of udev hooks that may still be holding the loopback open. Failing
to detach loopback devices was the reason we were seeing leaked tmpfs
volumes.

It moves cleanup_dirs and run_d functions from img-functions to

d9a2211d14 Only use tmpfs if build machine has 4GB+ RAM.
For machines with low RAM (or no access to /proc/meminfo) the builder
will still run, but will just build inside the filesystem that is
hosting /tmp. This will result in a slower build (especially if there
are a lot of .deb packages installed).

cb62bae9b8 Build images using loopdev instead of qemu-nbd.
Qemu-nbd does not perform well with older versions of qemu due to
the lack of writeback caching mode. It also only builds qcow2 images
and there is a desire for raw image support. Finally, qemu-nbd makes
it very difficult to build images concurrently due to the somewhat
opaque nature of how it selects a /dev/nbd# device. losetup, on
the other hand, makes this process very straight forward.
