v8: - Rebased on top of Stefan's block branch (0a35bce416) - The loop that pauses the block jobs in bdrv_drain_all() is now split in two: one that iterates the list of block jobs to stop them, and one that iterates the root bds in order to get the aio contexts.
v7: https://lists.gnu.org/archive/html/qemu-devel/2015-05/msg02580.html - Rebased against the current master - Updated bdrv_drain_all() to use the new block_job_next() API. v6: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg03046.html - fix the no-op test following Max's suggestions v5: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg03006.html - Fix a few typos - Minor documentation updates - Update test_stream_partial() to test no-ops - New test case: test_stream_parallel() - New test case: test_stream_overlapping() v4: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg01878.html - Refactor find_block_job to use the error from bdrv_lookup_bs() - Don't use QERR_DEVICE_IN_USE in block_job_create() since we can be dealing with nodes now. - Fix @device comment in the BlockJobInfo documentation - stream_start(): simplify the bdrv_reopen() call and use bdrv_get_device_or_node_name() for error messages. - Use a different variable name for BlockDriverState *i - Documentation fixes in docs/live-block-ops.txt - Update iotest 30 since now test_device_not_found() returns GenericError - Fix test case test_stream_partial() - Add new test case test_stream_intermediate() - Fix typos v3: https://lists.gnu.org/archive/html/qemu-devel/2015-04/msg00806.html - Keep a list of block jobs and make qmp_query_block_jobs() iterate over it. v2: https://lists.gnu.org/archive/html/qemu-devel/2015-03/msg04798.html - The 'block-stream' command does not have a 'node-name' parameter anymore and reuses 'device' for that purpose. - Block jobs can now be owned by any intermediate node, and not just by the ones at the root. query-block-jobs is updated to reflect that change. - The 'device' parameter of all 'block-job-*' commands can now take a node name. - The BlockJobInfo type and all BLOCK_JOB_* events report the node name in the 'device' field if the node does not have a device name. - All intermediate nodes are blocked (and checked for blockers) during the streaming operation. v1: https://lists.gnu.org/archive/html/qemu-devel/2015-02/msg04116.html === git backport-diff against v7 === Key: [----] : patches are identical [####] : number of functional differences between upstream/downstream patch [down] : patch is downstream-only The flags [FC] indicate (F)unctional and (C)ontextual differences, respectively 001/11:[0007] [FC] 'block: keep a list of block jobs' 002/11:[----] [--] 'block: allow block jobs in any arbitrary node' 003/11:[----] [--] 'block: never cancel a streaming job without running stream_complete()' 004/11:[----] [--] 'block: Support streaming to an intermediate layer' 005/11:[----] [--] 'block: Add QMP support for streaming to an intermediate layer' 006/11:[----] [--] 'docs: Document how to stream to an intermediate layer' 007/11:[----] [--] 'qemu-iotests: fix test_stream_partial()' 008/11:[----] [--] 'qemu-iotests: add no-op streaming test' 009/11:[----] [--] 'qemu-iotests: test streaming to an intermediate layer' 010/11:[----] [--] 'qemu-iotests: test block-stream operations in parallel' 011/11:[----] [--] 'qemu-iotests: test overlapping block-stream operations' Alberto Garcia (11): block: keep a list of block jobs block: allow block jobs in any arbitrary node block: never cancel a streaming job without running stream_complete() block: Support streaming to an intermediate layer block: Add QMP support for streaming to an intermediate layer docs: Document how to stream to an intermediate layer qemu-iotests: fix test_stream_partial() qemu-iotests: add no-op streaming test qemu-iotests: test streaming to an intermediate layer qemu-iotests: test block-stream operations in parallel qemu-iotests: test overlapping block-stream operations block.c | 4 +- block/io.c | 22 +++---- block/mirror.c | 5 +- block/stream.c | 44 ++++++++++++-- blockdev.c | 55 ++++++++--------- blockjob.c | 31 +++++++--- docs/live-block-ops.txt | 31 ++++++---- docs/qmp/qmp-events.txt | 8 +-- include/block/blockjob.h | 14 +++++ include/qapi/qmp/qerror.h | 3 - qapi/block-core.json | 30 +++++---- tests/qemu-iotests/030 | 148 ++++++++++++++++++++++++++++++++++++++++++++- tests/qemu-iotests/030.out | 4 +- 13 files changed, 307 insertions(+), 92 deletions(-) -- 2.1.4
