Why? on-success: Can conveniently synchronize a bitmap to a full backup. Allows for transactionless anchor backups. Allows us to attempt an anchor backup without damaging our bitmap until the backup is successful. Allows for transactional, ungrouped anchor backups. always: Allows us to resume full/top style backups with a later invocation to sync=3Dbitmap. Neat! Summary: 1-3: Refactor iotest 257 to accommodate this; 4-5: Augment 257 to test trivial failure cases 6-7: Implement feature 8: Test new feature John Snow (8): iotests/257: add Pattern class iotests/257: add EmulatedBitmap class iotests/257: Refactor backup helpers block/backup: hoist bitmap check into QMP interface iotests/257: test API failures block/backup: issue progress updates for skipped regions block/backup: support bitmap sync modes for non-bitmap backups iotests/257: test traditional sync modes block/backup.c | 22 +- blockdev.c | 32 + qapi/block-core.json | 6 +- tests/qemu-iotests/257 | 329 +++- tests/qemu-iotests/257.out | 3366 +++++++++++++++++++++++++++++++++++- 5 files changed, 3548 insertions(+), 207 deletions(-) --=20 2.21.0
