[Qemu-devel] [PATCH V2 00/11] add qmp/hmp interfaces for snapshot info

[Qemu-devel] [PATCH V2 00/11] add qmp/hmp interfaces for snapshot info

[Wenchao Xia]

  This serial of patches does two things: merge some info code
in qemu-img, and add following interfaces:
1) qmp: query-images
2) qmp: query-snapshots
3) hmp: show snapshot info on a single block device
  These patches follows the rule that use qmp to retieve information,
hmp layer just do a translation from qmp object it got, so almost
every hmp interface may have a correlated qmp interface.
  To make code graceful, snapshot retrieving code in qemu and qemu-img
are merged into block.c, and some function name was adjusted to make it
tips better. Now it works as:

   qemu          qemu-img

dump_monitor    dump_stdout
     |--------------| 
            |
           qmp
            |
          block

Note:
  Last two patches need previous sent patches which extend hmp sub command, at:
http://lists.nongnu.org/archive/html/qemu-devel/2012-12/msg03487.html

v2:
  Rename and adjusted qmp interface according to comments from Eric.
  Spelling fix.
  Information retrieving function in block layer goes to seperated patch.
  Free qmp object after usage in hmp.

Wenchao Xia (11):
  qemu-img: remove unused parameter in collect_image_info()
  block: add bdrv_get_filename() function
  block: add snapshot and image info query function
  qemu-img: switch image retrieving function
  block: rename bdrv_query_info to bdrv_query_block_info
  qmp: add interface query-images.
  block: export function bdrv_find_snapshot()
  qmp: add interface query-snapshots
  hmp: export function hmp_handle_error()
  hmp: retrieve info from qmp for snapshot info
  hmp: show snapshot on single block device
