By default none of the image formats were stored as compressed
file. The reason behind this was the assumption that some
formats automatically makes use of compression, which is true
but only in their processing and not in their data blocks at
creation time. Storage and handling of the image file itself
becomes cumbersome and therefore we change the default bundle
setup for image formats to be compressed. This means the image
as it gets packed by KIWI needs to be uncompressed before use.
The following image formats are affected by the change in a
call of the result bundler:
kiwi result bundle ...
* qcow2 (.qcow2.xz)
* vdi (.vdi.xz)
* vhd (.vhd.xz)
* vhdx (.vhdx.xz)
* vmdk (.vmdk.xz)
All other image formats already defined a custom bundling
setup including compression and are not affected by this change.
This Fixes#650
Do not resize the disk if an attempt to resize to the same
size was made. Do not fail in this situation but indicate
via a bool return value if an action has happened(True)
or not(False)
Stay compatible with the former version of kiwi and do not
compress disk formats like qcow2, vmdk, etc... It also does
not make much sense since the disk formats itself are using
a compression algorithm. Fixes#159
Add a generic store_to_result method which allows to store
the format result files into an instance of Result. This
allows to customize result handling per format when needed
nose is no longer maintained, thus we have to move to another
testing system. This commit updates the tox setup and all tests
to use pytest instead of nose.
