This series adds support for incremental backup primitives in QMP transactions. It requires my transactionless incremental backup series.
Patch 1 adds basic support for add and clear transactions. Patch 2 tests this basic support. Patches 3-7 add support for error scenarios where only some incremental backup jobs complete during a transaction. See commits for patches #3 and #7 for more details, as these are likely to be the most controversial additions. Patches 8-11 test the feature added in 3-7. --js John Snow (11): qapi: Add transaction support to block-dirty-bitmap operations iotests: add transactional incremental backup test block: add transactional callbacks feature block: add refcount to Job object block: add delayed bitmap successor cleanup qmp: Add an implementation wrapper for qmp_drive_backup block: drive_backup transaction callback support iotests: add QMP event waiting queue iotests: test 124 - drive object refactoring iotests: 124 - backup_prepare refactoring iotests: 124 - transactional failure test block.c | 79 +++++++- block/backup.c | 32 +-- blockdev.c | 441 ++++++++++++++++++++++++++++++++++++++++-- blockjob.c | 18 +- include/block/block.h | 11 +- include/block/block_int.h | 8 + include/block/blockjob.h | 21 ++ qapi-schema.json | 6 +- tests/qemu-iotests/124 | 363 +++++++++++++++++++++++++++------- tests/qemu-iotests/124.out | 4 +- tests/qemu-iotests/iotests.py | 38 ++++ 11 files changed, 896 insertions(+), 125 deletions(-) -- 1.9.3
