[pve-devel] [PATCH proxmox-backup/common/storage/wt v2] improve file-restore timeout behaviour

[Dominik Csapak]

this series improves the behaviour of the file-restore when some mount
operations take longer than the 30 second pveproxy timeout, and improves
the startup speed of the restore vm

we do this by moving the disk init into the background of the daemon
startup, while the hyper server is starting, and by adding a timeout
option to the file-restore binary.

to be able to report the error back to the gui, we return a
'SERVICE_UNAVAILABLE' error in the timeout case, and the gui tries
again (up to 10 times).

backup patches 2,3 could be applied independently, as they even make
sense withouth the rest

pve-storage depends on a new pve-common&file-restore

widget-toolkit makes only sense with the other patches, but is
designed to not change behaviour with the old api

alternatively i could drop the 'json-error' parameter and do it
always, or when timeout it set.

changes from v1:
* rebased on master
* moved the json-error and timeout directly into pve-common (hardcoded)
  since there is only one usage of that function

proxmox-backup:

Dominik Csapak (5):
  restore-daemon: start disk initialization in parallel to the api
  restore-daemon: put blocking code into 'block_in_place'
  restore-daemon: avoid auto-mounting zpools
  file-restore: factor out 'list_files'
  file-restore: add 'timeout' and 'json-error' parameter
