Hi,

This patchset contains various improvements for the image creation functionality
made by Patchick Ohly during his work on bug #9076:
 - renamed COMPRESSION variables to CONVERSION as the term "compression" is no longer accurate
 - support converting masked types

Changes in v2: rebased on top of master-next
               returned image_getdepends back to image_types.bbclass
Changes in v3: rebased on top of recent master
Changes in v4: rebased on top of recent master
Changes in v5: removed 2 problematic patches

The following changes since commit 5b61fa04a335a4fdefd435dc25d4bac41ee21e39:

  bitbake: toaster-tests: fix URL given for Chromedriver download (2016-07-29 09:53:32 +0100)

are available in the git repository at:

From: Patrick Ohly <patrick.ohly@intel.com>

Conversion to vmdk/vdi/qcow2 is also useful for other base images
types, not just for .hdddirect. This can be achieved by definining
them as conversion commands and relying on the conversion chaining
to convert arbitrary base images.

For this to work when the base image gets created by a masked image
type, the additional conversion commands now get executed in a
do_image_complete prefunc.

With all of that in place it becomes possible to remove the special
purpose code for vmdk/vdi/qcow2 types from image-vm.bbclass and
several other classes. This has (intentional!) implications on the
valid IMAGE_FSTYPES and the file suffices: now
"hdddirect.vmdk/vdi/qcow2" must be used as IMAGE_FSTYPES to select the
former special-case types "vmdk/vdi/qcow2", and the image files and
links will also have the extra .hdddirect suffix.

This is intentional because it makes it makes it possible to
distinguish between virtual machine images created from .hdddirect and
those created from other base images.

The new support for virtual machine images can also be combined with
compression, thus making it possible to create image files for
publication in compressed format, for example with:
  IMAGE_FSTYPES = "hdddirect.vdi.xz"

I'm afraid I really don't like this. The direction this code has taken
is to separate out the different steps into clearly identifiable tasks.
This was due to strong user feedback that nobody could figure out what
was going on. This change starts to merge them all back together,
hiding them in a prefunc of a task which is just horrible.

I haven't looked in detail at the problem thats being attempted to be
solved here but this doesn't look like a good approach at all and takes
us backwards rather than forwards.

So, sorry, but no.

Cheers,

Richard

Staring at and thinking about this some more, I think the description
doesn't do this patch any favours. I'd phrase this as:

"Make the vmdk/vdi/qcow2 image types behave more as compression type
post processes".

I'm more than fine with that and it makes sense. I don't however think
the "masked" bits of this patch look right. These should be able to
become compression types without the masked changes.

Its possible there is another step this patch is trying to make, such
as supporting chained compression. If that is the case it should be a
separate patch.

Cheers,

Richard

Thank you for reviewing this.

OK, I'll drop this one too. I'll send only one COMPRESSION->CONVERSION
patch as it fixes 2.2M3 bug.

From: Patrick Ohly <patrick.ohly@intel.com>

With the enhanced functionality, the term "compression" is no longer
accurate, because the mechanism also gets used for conversion
operations that do not actually compress data.

It is possible to remove this naming problem in a backward-compatible
manner by including COMPRESSIONTYPES in CONVERSIONTYPES and checking for
the old COMPRESS_CMD/DEPENDS as fallbacks.
