From 3c95037aa857e95916b2a91e127ec9b74af8ed05 Mon Sep 17 00:00:00 2001 From: John Snow Date: Mon, 29 Jul 2019 16:35:52 -0400 Subject: [PATCH 01/36] qapi/block-core: Introduce BackupCommon drive-backup and blockdev-backup have an awful lot of things in common that are the same. Let's fix that. I don't deduplicate 'target', because the semantics actually did change between each structure. Leave that one alone so it can be documented separately. Where documentation was not identical, use the most up-to-date version. For "speed", use Blockdev-Backup's version. For "sync", use Drive-Backup's version.

Create a new mode simply named "BITMAP" that is designed to make use of the new Bitmap Sync Mode field. Because the only bitmap sync mode is 'on-success', this adds no new functionality to the backup job (yet). The old incremental backup mode is maintained as a syntactic sugar for sync=bitmap, mode=on-success. Add all of the plumbing necessary to support this new instruction.

Regardless of if the job succeeds or fails, the bitmap is *always* synchronized. This means that for backups that fail part-way through, the bitmap retains a record of which sectors need to be copied out to accomplish a new backup using the old, partial result. In effect, this allows us to "resume" a failed backup; however the new backup will be from the new point in time, so it isn't a "resume" as much as it is an "incremental retry." This can be useful in the case of extremely large backups that fail considerably through the operation and we'd like to not waste the work that was already performed.

In the write notifier handler, we dutifully copy out such regions. Fix this in three parts: 1. Mark the bitmap as being initialized before the first yield. 2. After the first yield but before the backup loop, interrogate the allocation status asynchronously and initialize the bitmap. 3. Teach the write notifier to interrogate allocation status if it is invoked during bitmap initialization. As an effect of this patch, the job progress for TOP backups now behaves like this: - total progress starts at bdrv_length. - As allocation status is interrogated, total progress decreases. - As blocks are copied, current progress increases. Taken together, the floor and ceiling move to meet each other.

This allows us to do things like create a bitmap synced to a full backup without a transaction, or start a resumable backup process. Some combinations don't make sense, though: - NEVER policy combined with any non-BITMAP mode doesn't do anything, because the bitmap isn't used for input or output. It's harmless, but is almost certainly never what the user wanted. - sync=NONE is more questionable. It can't use on-success because this job never completes with success anyway, and the resulting artifact of 'always' is suspect: because we start with a full bitmap and only copy out segments that get written to, the final output bitmap will always be ... a fully set bitmap. Maybe there's contexts in which bitmaps make sense for sync=none, but not without more severe changes to the current job, and omitting it here doesn't prevent us from adding it later.
