2013-07-26Add tests for sync modes 'TOP' and 'NONE'Ian Main6-2/+113
This patch adds tests for sync modes top and none. Test for 'TOP' is separated out as it requires a backing file. Also added a test for invalid format. Signed-off-by: Ian Main <imain@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-07-26Implement sync modes for drive-backup.Ian Main4-38/+101
This patch adds sync-modes to the drive-backup interface and implements the FULL, NONE and TOP modes of synchronization. FULL performs as before copying the entire contents of the drive while preserving the point-in-time using CoW. NONE only copies new writes to the target drive. TOP copies changes to the topmost drive image and preserves the point-in-time using CoW. For sync mode TOP are creating a new target image using the same backing file as the original disk image. Then any new data that has been laid on top of it since creation is copied in the main backup_run() loop. There is an extra check in the 'TOP' case so that we don't bother to copy all the data of the backing file as it already exists in the target. This is where the bdrv_co_is_allocated() is used to determine if the data exists in the topmost layer or below. Also any new data being written is intercepted via the write_notifier hook which ends up calling backup_do_cow() to copy old data out before it gets overwritten. For mode 'NONE' we create the new target image and only copy in the original data from the disk image starting from the time the call was made. This preserves the point in time data by only copying the parts that are *going to change* to the target image. This way we can reconstruct the final image by checking to see if the given block exists in the new target image first, and if it does not, you can get it from the original image. This is basically an optimization allowing you to do point-in-time snapshots with low overhead vs the 'FULL' version. Since there is no old data to copy out the loop in backup_run() for the NONE case just calls qemu_coroutine_yield() which only wakes up after an event (usually cancel in this case). The rest is handled by the before_write notifier which again calls backup_do_cow() to write out the old data so it can be preserved.

2013-07-26Implement qdict_flatten()Kevin Wolf2-0/+52
qdict_flatten(): For each nested QDict with key x, all fields with key y are moved to this QDict and their key is renamed to "x.y". This operation is applied recursively for nested QDicts. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2013-07-26blockdev: Split up 'cache' optionKevin Wolf1-10/+47
The old 'cache' option really encodes three different boolean flags into a cache mode name, without providing all combinations. Make them three separate options instead and translate the old option to the new ones for drive_init(). The specific boolean options take precedence if the old cache option is specified as well, so the following options are equivalent: -drive file=x,cache=none,cache.no-flush=true -drive file=x,cache.writeback=true,cache.direct=true,cache.no-flush=true Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>

In QMP, we want to use dashes instead of underscores in QMP argument names, and use nested options for throttling.

2013-07-26qapi: Anonymous unionsKevin Wolf10-0/+160
The discriminator for anonymous unions is the data type. This allows to have a union type that allows both of these: { 'file': 'my_existing_block_device_id' } { 'file': { 'filename': '/tmp/mydisk.qcow2', 'read-only': true } } Unions like this are specified in the schema with an empty dict as discriminator. For this example you could take: { 'union': 'BlockRef', 'discriminator': {}, 'data': { 'definition': 'BlockOptions', 'reference': 'str' } } { 'type': 'ExampleObject', 'data: { 'file': 'BlockRef' } } Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
