[Qemu-devel] [PATCH] qmp-commands.hx: Update the supported 'transaction' operations

[Qemu-devel] [PATCH] qmp-commands.hx: Update the supported 'transaction' operations

[Kashyap Chamarthy]

Although the canonical source of reference for QMP commands is
qapi-schema.json, for consistency's sake, update qmp-commands.hx to
state the list of supported transactionable operations, namely:

    drive-backup
    blockdev-backup
    blockdev-snapshot-internal-sync
    abort
    block-dirty-bitmap-add
    block-dirty-bitmap-clear

Also update the possible values for the "type" action array.

Significant enough changes that I would have dropped R-b before posting
to ensure it gets looked at. But fortunately, you did a good job, so you
can still keep my R-b.

Yes, I was wary of this and thought I included a blurb "Removing Eric's
R-b as this change involves more edits."  My bad, seems to have missed
it while message composition.  And, your reminder doesn't hurt.

Do you want to extend this list, too? Right now it only contains
parameter information for blockdev-snapshot-sync and
blockdev-snapshot-internal-sync.

You mean, all the parameters for rest of the transactionable commands
that one can possibly add (taking block-core.json)?

E.g. for 'drive-backup' command, all the possible data ('device',
target', 'format', 'sync', etc) one can provide (which are enumerated in
the DriveBackup struct):


    $ less qapi/block-core.json
    [...]
    { 'struct': 'DriveBackup',
      'data': { 'device': 'str', 'target': 'str', '*format': 'str',
                'sync': 'MirrorSyncMode', '*mode': 'NewImageMode',
                '*speed': 'int', '*bitmap': 'str',
                '*on-source-error': 'BlockdevOnError',
                '*on-target-error': 'BlockdevOnError' } }
    [...]

And, data provided by 'BlockdevBackup' struct for 'blockdev-backup', so
on.

If so, I can do try that if that's the preferred way, but maybe it can
be done as a separate commit, since it's been that way for a while?

Or conversely, we could drop the action-specific arguments, and just say
something like "see the documentation for specific additional fields
appropriate for that action"

Yes, at this point, a separate commit for any further cleanups is fine.

This is the approach that's most flexible. As it stands upstream right
now, all of the various actions simply have an identical command layout
to their respective QMP versions, so it'd be easiest to just point to
the various singlet commands.

We'll prevent desync and bad documentation that way. If we ever add
extra arguments per-transaction (like this patchset proposes,) we can
always just document the difference.

Isn't the actions limited by the TransactionAction in qapi-schema.json?

 { 'union': 'TransactionAction',
   'data': {
        'blockdev-snapshot-sync': 'BlockdevSnapshot',
        'drive-backup': 'DriveBackup',
+       'blockdev-backup': 'BlockdevBackup',
        'abort': 'Abort',
        'blockdev-snapshot-internal-sync': 'BlockdevSnapshotInternal'
    } }

It looks like block-dirty-bitmap-add/clear isn't in the list.

Another thing I didn't notice: I enntered the same command name twice.

Thanks. I'll send a v2 fixing what you found and the other mistake
(double entry of the same command) in the commit message.

[Qemu-devel] [PATCH] qmp-commands.hx: Update the supported 'transaction' operations

[Kashyap Chamarthy]

Although the canonical source of reference for QMP commands is
qapi-schema.json, for consistency's sake, update qmp-commands.hx to
state the list of supported transactionable operations, namely:

    drive-backup
    blockdev-backup
    blockdev-snapshot-internal-sync
    abort
    block-dirty-bitmap-add
    block-dirty-bitmap-clear

NB: The 'block-dirty-bitmap-add' and 'block-dirty-bitmap-add' commands
will be available once the in-review "transactionless incremental
backup" patch series[1] is merged upstream.
