This is 11th version of patch adding compare subcommand that
compares two images. Compare has following criteria:
- only data part is compared
- unallocated sectors are not read
- qemu-img returns:
- 0 if images are identical
- 1 if images differ
- >2 error on execution
v11:
- add minor enhancements to qemu-img compare test (patch 4)
v10:
- rebased to kwolf's block-next branch due to conflict patch (patch 2)
- exit status updates (patch 3)
- minor non-functional fixes
v9:
- Merged patch 3 and 4 (subcommmand implementation and documentation) of v8
- Added basic test for qemu-img compare
- Fixed incorrect indentation
- add bdrv_is_allocated_above() return value check
- Add description of exit codes into the documentation
- minor non-functional changes
v8:
- minor grammar fixes (no behavior change)
v7:
- split patch into pieces
- Quiet mode added for all relevant subcommands
- check non-shared part of disk after shared one
- minor docummentation and naming fixes
v6:
- added handling -?, -h options for compare subcommand
v5 (only minor changes):
- removed redundant comment
- removed dead code (goto after help())
- set final total_sectors on first assignment
v4:
- Fixed various typos
- Added functions for empty sector check and sector-to-bytes offset
conversion
- Fixed command-line parameters processing
v3:
- options -f/-F are orthogonal
- documentation updated to new syntax and behavior
- used byte offset instead of sector number for output
v2:
- changed option for second image format to -F
- changed handling of -f and -F [1]
- added strict mode (-s)
- added quiet mode (-q)
- improved output messages [2]
- rename variables for larger image handling
- added man page content
