[Qemu-devel] [PATCH v6 00/11] Support streaming to an intermediate layer

Subject: [Qemu-devel] [PATCH v6 00/11] Support streaming to an intermediate layer
Date: Fri, 24 Apr 2015 18:01:44 +0300

- 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
- 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
- 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.

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
