This adds the "read-only" option to the QDict. One important effect of this change is that when a child inherits options from its parent, the existing "read-only" mode can be preserved if it was explicitly set previously. This addresses scenarios like this: [E] <- [D] <- [C] <- [B] <- [A] In this case, if we reopen [D] with read-only=off, and later reopen [B], then [D] will not inherit read-only=on from its parent during the bdrv_reopen_queue_child() stage. The BDRV_O_RDWR flag is not removed yet, but its keep in sync with the value of the "read-only" option. Signed-off-by: NAlberto Garcia <berto@igalia.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

The patch adds a flag to the qmp/hmp drive-backup command which enables block compression. Compression should be implemented in the format driver to enable this feature. There are some limitations of the format driver to allow compressed writes. We can write data only once. Though for backup this is perfectly fine.

When I/O limits are set for a block device, the name of the throttling group is taken from the BlockBackend if the user doesn't specify one. Commit efaa7c4e moved the naming of the BlockBackend in blockdev_init() to the end of the function, after I/O limits are set. The consequence is that the throttling group gets an empty name.

find_block_job() looks for a block backend with a specified name, checks whether it has a block job and acquires its AioContext. We want to identify jobs by their ID and not by the block backend they're attached to, so this patch ignores the backends altogether and gets the job directly. Apart from making the code simpler, this will allow us to find block jobs once they start having user-specified IDs. To ensure backward compatibility we keep ERROR_CLASS_DEVICE_NOT_ACTIVE as the error class if the job doesn't exist. In subsequent patches we'll also need to keep the device name as the default job ID if the user doesn't specify a different one.

Making each output visitor provide its own output collection function was the only remaining reason for exposing visitor sub-types to the rest of the code base. Add a polymorphic visit_complete() function which is a no-op for input visitors, and which populates an opaque pointer for output visitors. For maximum type-safety, also add a parameter to the output visitor constructors with a type-correct version of the output pointer, and assert that the two uses match. This approach was considered superior to either passing the output parameter only during construction (action at a distance during visit_free() feels awkward) or only during visit_complete() (defeating type safety makes it easier to use incorrectly). Most callers were function-local, and therefore a mechanical conversion; the testsuite was a bit trickier, but the previous cleanup patch minimized the churn here. The visit_complete() function may be called at most once; doing so lets us use transfer semantics rather than duplication or ref-count semantics to get the just-built output back to the caller, even though it means our behavior is not idempotent.

Currently, we are trying to move the backing BDS from the source to the target in bdrv_replace_in_backing_chain() which is called from mirror_exit(). However, mirror_complete() already tries to open the target's backing chain with a call to bdrv_open_backing_file(). First, we should only set the target's backing BDS once. Second, the mirroring block job has a better idea of what to set it to than the generic code in bdrv_replace_in_backing_chain() (in fact, the latter's conditions on when to move the backing BDS from source to target are not really correct). Therefore, remove that code from bdrv_replace_in_backing_chain() and leave it to mirror_complete(). Depending on what kind of mirroring is performed, we furthermore want to use different strategies to open the target's backing chain: - If blockdev-mirror is used, we can assume the user made sure that the target already has the correct backing chain. In particular, we should not try to open a backing file if the target does not have any yet. - If drive-mirror with mode=absolute-paths is used, we can and should reuse the already existing chain of nodes that the source BDS is in. In case of sync=full, no backing BDS is required; with sync=top, we just link the source's backing BDS to the target, and with sync=none, we use the source BDS as the target's backing BDS. We should not try to open these backing files anew because this would lead to two BDSs existing per physical file in the backing chain, and we would like to avoid such concurrent access. - If drive-mirror with mode=existing is used, we have to use the information provided in the physical image file which means opening the target's backing chain completely anew, just as it has been done already. If the target's backing chain shares images with the source, this may lead to multiple BDSs per physical image file. But since we cannot reliably ascertain this case, there is nothing we can do about it.
