adb0341064 Add block-device defaults
This moves the block-device default out of the "vm" element and into a
selection of other elements.  There's "mbr" which retains the status
quo.  There's an EFI version that has the boot/grub partitions as
required.  In between there's the GPT only version, which is useful
for architectures like power without EFI, but still want possible
larger disks using GPT.

55b479b54f GPT partitioning support
This adds support for a GPT label type to the partitioning code.  This
is relatively straight-forward translation of the partition config
into a sgparted command-line and subsequent call.

A unit test is added based on a working GPT/EFI configuration and the
fedora-minimal functional test is updated to build a single-partition
GPT based using the new block-device-gpt override element.  See notes
in the sample configuration files about partition requirements and
types.

Documentation has been updated.

271dc36f33 Add zipl element as s390x architecture bootloader
s390x architecture uses zipl as bootloader. When used in combination
with the vm element it replaces the existing bootloader element.
It's mandatory for s390x vm images.

Use cases
---------

* Allow users to create s390x images that run on nova with s390x
  libvirt/kvm backend
* Building nodepool images for s390x third party CI

Supported Distros
-----------------
The following listing shows all Distros that officially support
s390x and how those Distros are supported in DIB with this patch.

* SLES - not supported (SLES is not supported in DIB)
* RHEL - not suppoprted (RHEL is not supported as KVM guest on s390x,
                         therefore there's no rhel7 qcow image for s390x available
                         like it is for other archictectures)
* Ubuntu - supported

Ubuntu images can for example be built using the following commands:

  $ disk-image-create ubuntu-minimal zipl vm
  $ disk-image-create ubuntu-minimal zipl
  $ disk-image-create ubuntu zipl vm

Testing
-------

Cross architecture building of s390x images is not supported so far.

The plan is to set up a ThirdParty CI that builds the image for s390x and
provides the logs.

Amrith Kumar
52faa0e1d9 Allow users to specify partition type in the MBR PTE
The MBR Partition Table Entry (PTE) allows one to specify many
possible partition types and one of the benefits of this is being able
to specify the CHS variant or the LBA variant.

By default, LBA only creates partitions of type 0x83 (of course,
that's only because the documentation doesn't tell you how to make it
do anything else).

I will take up Ian's suggestion in patch set 2 for a more rigorous
test in an independent patch set.

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.

e4e23897a1 Refactor: block-device filesystem creation, mount and fstab
This patch finalizes the block device refactoring.  It moves the three
remaining levels (filesystem creation, mount and fstab handling) into
the new python module.

Now it is possible to use any number of disk images, any number of
partitions and used them mounted to different directories.

Notes:

 * unmount_dir : modified to only unmount the subdirs mounted by
   mount_proc_sys_dev().  dib-block-device unmounts
   $TMP_MOUNT_PATH/mnt (see I85e01f3898d3c043071de5fad82307cb091a64a9)

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.

(This is a reworking of I31d2b6050b6c46fefe37378698e9a330025db430 for
the feature/v2 branch)

740c0a85df Merge "Move generation of dib_[environment|args] to manifest element" 2017-02-07 20:23:06 +00:00
Andreas Florath
870374c8da Move generation of dib_[environment|args] to manifest element
dib_[environment|args] manifest files are currently generated by the
base element and then moved by the manifest element.

This creates too many corner cases -- if you don't include the base
element (we are trying to empty it ATM) you don't get the env/args
saved at all; if you include base but don't include the manifest
element they're saved to /etc, but if you do have the manifest element
they're moved to the manifest dir.

Move generation of these into the manifest element directly and update
the documentation to reflect this.  In practice this doesn't change
things, because the "manifests" element gets pulled in via deps for
most builds.

5e2330d89c Put MKFS_OPTS after filesystem type
mkfs's arguments are

 mkfs [options] [-t type] [fs-options] device [size]

So it seems our MKFS_OPTS are really supposed to be fs-options, rather
than options to mkfs itself.

Why didn't we notice?  It's quite a trap -- mkfs.ext2 has a "-t"
option, so when we're calling

 $ mkfs -i 4096 ... -t ext4 ...

We actually just fall-back to the default from the mkfs wrapper which
is mkfs.ext2 which works!  But when you make that, say, xfs, we're not
calling the right wrapper at all.

Also update documentation

d65678678e Move dib-run-parts into diskimage-builder
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.

<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__.

9e392f56b0 Don't set tracing in environment files
Because environment files are sourced into the current environment,
they shouldn't be setting global settings like tracing else they
affect every preceeding import.  This is quite confusing when only
half your imports are traced in the logs, because it was either turned
on, or off, by a preceeding environment import.

There is a corresponding dib-run-parts change in
I29f7df1514aeb988222d1094e8269eddb485c2a0 that will greatly increase
debugability for environment files by deliberately logging what files
are sourced and consistently turning on tracing around their import.

This isn't strictly necessary (since dib-run-parts with the prior
change will just turn tracing off after import anyway) but it's a
decent cleanup for consistency.  A bare-minimum dib-lint check is
added.  Documentation is updated.

Update the documentation to explain how to run it for development.  I
don't think we should support the idea that you can check-out the code
and run ./bin/disk-image-create -- it has dependencies (dib-utils,
etc) and needs to be run from a virtualenv (this is what CI in the
gate does).  A follow-up can clean-up some of the path munging stuff
we have for this in disk-image-create.

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.

20bb6a0255 Add option to be able to run_functests.sh in parallel
Running the functional tests is time consuming.  This patch adds the
option `-j <job count>` to the tests/run_functests.sh: when given the
test run in parallel up the <job count> jobs.
When using this, be sure to have enough resources (CPUs, RAM and HD
space) on the host.

In addition there was the need to change two things:
o Global /tmp/dib-test-should-fail was move to temporary build
  directory of each execution.
o Because the logs might now interleave, each log line has now a
  prefix of the name of the testcase.

[In my environment running functests sequential takes 15+ minutes,
running them parallel takes less than 6 minutes.]

672705831f Add a best-effort sudo safety check
As motivation for this; we have had two breakouts of dib in recent
memory.  One was a failure to unmount through symlinks in the core
code (I335316019ef948758392b03e91f9869102a472b9) and the other was
removing host keys on the build-system
(Ib01d71ff9415a0ae04d963f6e380aab9ac2260ce).

For the most part, dib runs unprivileged.  Bits of the core code are
hopefully well tested (modulo bugs like the first one!).  We give free
reign inside the chroot (although there is still some potential there
for adverse external affects via bind mounts).  Where we could be a
bit safer (and could have prevented at least the second of these
breakouts) is with some better checking that the "sudo" calls
*outside* the chroot at least looked sane.

This adds a basic check that we're using chroot or image paths when
calling sudo in those parts of elements that run *outside* the chroot.
Various files are updated to accomodate this check; mostly by just
ignoring it for existing code (I have not audited these calls).

Nobody is pretending this type of checking makes dib magically safe,
or removes the issues with it needing to do things as root during the
build.  But this can help find egregious errors like the key removal.

b18f71f781 Rework functional test runner
This simplifies and enhances the functional-test runner script for
much better interactive behaviour and to give us the ability to better
choose what is running in CI.

Firstly, I have split the image-output testing into a separate script.
This is not actually part of the functional testing of elements and is
both logically and functionally different.  It currently does not run
in upstream CI because we don't have docker in the images.  I have
nothing against it, but it can be it's own thing.

run_functests.sh is overhauled to have a useful interactive interface,
e.g.

---
 $ ./run_functests.sh -h
 run_functests.sh [-h] [-l] <test> <test> ...
   -h : show this help
   -l : list available tests
   <test> : functional test to run
            Special test 'all' will run all tests

 $ ./run_functests.sh -l
 The available functional tests are:

  apt-sources/test-sources
  debian/build-succeeds
  fedora/build-succeeds
  fedora/build-succeeds-f21
  ironic-agent/build-succeeds-fedora
---

As described there, you can run a single test, a number of tests, the
default tests (as CI will do) or all tests.  Running all tests is too
much for regular CI, but currently the only way to stop a low priority
test running, or temporarily pause is to remove it completely --
clearly sub-optimal (see I93c2990472e88ab3e5ff14db56b4ff1b4dd965ef).

There is nothing complicated about this, and to further simplify I
have merged the runner functions back into run_functests.sh which
remains a very modest ~150 lines, with most of that being argument
sanity.  With that and the image-format cleanup, we can remove the
indirection of the 3 small library files.

For consistency, I have renamed the "dib_functions_test" (that tests
things from the dib functions library) with a run_* prefix.

Because the default list is the same as the current functional tests
run, this does not modify the status-quo.  I plan to modify this,
however, to run fedora-minimal & centos-minimal tests in a future
change, as these are required to be stable for openstack ci.

Documentation is updated, and a README.rst is added in the tests
directory for discoverability.
