[pve-devel] [PATCH pve-qemu 1/5] Add transaction patches and fix for blocking finish

Stefan Reiter s.reiter at proxmox.com
Mon Sep 28 17:48:32 CEST 2020


With the transaction patches, patch 0026-PVE-Backup-modify-job-api.patch
is no longer necessary, so drop it and rebase all following patches on
top.

Signed-off-by: Stefan Reiter <s.reiter at proxmox.com>
---

The following three patches marked "qemu" in the email chain are the same as the
ones being added here, for easier review/commenting. I sent the patch-of-patches
since the "modify job API" patch needs to be dropped for transaction support to
work.

The fix for the bug discussed (VM hang on server-side verify) is patch 4 of 5,
now based on top of transaction support (makes some changes easier, less code
requires fixing).

Patch 5 makes log output for backups look a bit nicer with the new "finishing"
flag, but no dependencies are created (old and new versions on both sides should
continue working fine).

-Subject: [PATCH] PVE-Backup: modify job api
-
-Introduce a pause_count parameter to start a backup in
-paused mode. This way backups of multiple drives can be
-started up sequentially via the completion callback while
-having been started at the same point in time.

+Subject: [PATCH] PVE-Backup: Use a transaction to synchronize job states
+
+By using a JobTxn, we can sync dirty bitmaps only when *all* jobs were
+successful - meaning we don't need to remove them when the backup fails,
+since QEMU's BITMAP_SYNC_MODE_ON_SUCCESS will now handle that for us.
+
+To keep the rate-limiting and IO impact from before, we use a sequential
+transaction, so drives will still be backed up one after the other.

+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Stefan Reiter <s.reiter at proxmox.com>
+Date: Mon, 28 Sep 2020 13:40:51 +0200
+Subject: [PATCH] PVE-Backup: Use more coroutines and don't block on finishing
+
+proxmox_backup_co_finish is already async, but previously we would wait
+for the coroutine using block_on_coroutine_fn(). Avoid this by
+scheduling pvebackup_co_complete_stream (and thus pvebackup_co_cleanup)
+as a real coroutine when calling from pvebackup_complete_cb. This is ok,
+since complete_stream uses the backup_mutex internally to synchronize,
+and other streams can happily continue writing in the meantime anyway.
+
+To accomodate, backup_mutex is converted to a CoMutex. This means
+converting every user to a coroutine. This is not just useful here, but
+will come in handy once this series[0] is merged, and QMP calls can be
+yield-able coroutines too. Then we can also finally get rid of
+block_on_coroutine_fn.
+
+Cases of aio_context_acquire/release from within what is now a coroutine
+are changed to aio_co_reschedule_self, which works since a running
+coroutine always holds the aio lock for the context it is running in.
+
+job_cancel_sync is changed to regular job_cancel, since job_cancel_sync
+uses AIO_WAIT_WHILE internally, which is forbidden from Coroutines.
+
+create_backup_jobs cannot be run from a coroutine, so it is run
+directly. This does however mean that it runs unlocked, as it cannot
+acquire a CoMutex (see it's comment for rational on why that's ok).
+
+To communicate the finishing state, a new property is introduced to
+query-backup: 'finishing'. A new state is explicitly not used, since
+that would break compatibility with older qemu-server versions.
