Instead of just checking once in exactly this order if there are dependendies, non-COW clusters and new allocation, this starts looping around these. This way we can, for example, gather non-COW clusters after new allocations as long as the host cluster offsets stay contiguous. Once handle_dependencies() is extended so that COW areas of in-flight allocations can be overwritten, this allows to continue with gathering other clusters (we wouldn't be able to do that without this change because we would have missed a possible second dependency in one of the next clusters). This means that in the typical sequential write case, we can combine the COW overwrite of one cluster with the allocation of the next cluster as soon as something like Delayed COW gets actually implemented. It is only by avoiding splitting requests this way that Delayed COW actually starts improving performance noticably.

This should be based on the virtual disk size, not on the size of the image. Interesting observation: With some VM state stored in the image file, percentages higher than 100% are possible, even though snapshots themselves are ignored. This is a qcow2 bug to be fixed another day: The VM state should be discarded in the active L2 tables after completing the snapshot creation.

Show how many clusters are compressed. This can be used to monitor how many compressed clusters remain and whether to recompress the image. Suggested-by: NCole Robinson <crobinso@redhat.com> Signed-off-by: NStefan Hajnoczi <stefanha@redhat.com>

This patch adds the support for reporting the image end offset (in bytes). This is particularly useful after a conversion (or a rebase) where the destination is a block device in order to find the first unused byte at the end of the image.

Actually writing all the content with 512 byte sector size would take forever, therefore build the image file with a Python script and use qemu-io for the last write that actually triggers the refcount table growth. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Add a test for each of report/ignore/stop. The tests use blkdebug to generate an error in the middle of a script. The error is recoverable (once = "on") so that we can test resuming a job after stopping for an error.

These check that a paused streaming job does not advance its offset. Sometimes the new test fails; the map is different between the source and the destination of the streaming because qemu-io does not always pack adjacent clusters that have the same allocated/unallocated state. However, this also happens with the existing test_stream testcase, and is better fixed in qemu-io.

Add tests to exercise the InvalidParameter 'speed' error code path, as well as the regular success case for setting the speed. The block-stream 'speed' parameter allows the speed limit of the job to be applied immediately when the job starts instead of issuing a separate block-job-set-speed command later. If the parameter has an invalid value we expect to get an error and the job is not created. It turns out that cancelling a block job is a common operation in these test cases, let's extract a cancel_and_wait() function instead of duplicating the QMP commands.
