From: Patrick Ohly <patrick.ohly@intel.com>
When using conversion chaining (for example example: .dsk.vdi.xz),
the imagetypes_getdepends() did not properly detect all compression
commands (thus skipping the corresponding COMPRESS_DEPENDS) and
the base type, leading to missing dependencies of the image's do_rootfs
task.
This is not a big problem in practice because in those cases where
conversion chaining is useful (as in the example above), the missing
dependency is qemu-native, which typically gets built anyway.
imagetypes_getdepends() had hard-coded special treatment for certain
image types. This gets replaced with setting the normal IMAGE_DEPENDS
variables for these types.

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"

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.

To: openembedded-core
From: Patrick Ohly <patrick.ohly@intel.com>
If a certain image type can be created both by applying conversion
commands to a base type as well as via a specialized command (like a
fictious IMAGE_CMD_ext4.xz, or some dedicated task, as indicated by
IMAGE_TYPES_MASKED = ext4.xz), then pick the more specialized method
and skip generating the conversion commands.
That way developers can choose between using the builtin conversion
support or re-implementing certain types, for example more efficiently
without intermediate files.
