Requires: <20190709232550.10724-1-js...@redhat.com> [PATCH v4 00/18] bitmaps: introduce 'bitmap' sync mode
This follows the previous series which adds the 'bitmap' sync mode and uses it to add interactions with bitmaps to the 'full' and 'top' modes to blockdev-backup and drive-backup. 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=bitmap. 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(-) -- 2.21.0
