BZ: 980771
218e99
218e99
In _img_info, filter out additional information specific to the image
218e99
format provided by qemu-img info, since tests designed for multiple
218e99
image formats would produce different outputs for every image format
218e99
otherwise.
218e99
218e99
In a human-readable dump, that new information will always be last for
218e99
each "image information block" (multiple blocks are emitted when
218e99
inspecting the backing file chain). Every block is separated by an empty
218e99
line. Therefore, in this case, everything starting with the line "Format
218e99
specific information:" up to that empty line (or EOF, if it is the last
218e99
block) has to be stripped.
218e99
218e99
The JSON dump will always emit pretty JSON data. Therefore, the opening
218e99
and closing braces of every object will be on lines which are indented
218e99
by exactly the same amount, and all lines in between will have more
218e99
indentation. Thus, in this case, everything starting with a line
218e99
matching the regular expression /^ *"format-specific": {/ until /^ *},?/
218e99
has to be stripped, where the number of spaces at the beginning of the
218e99
respective lines is equal.
