[pve-devel] [PATCH v2 00/13] Single-file-restore GUI for PBS snapshots

[Stefan Reiter <s.reiter@proxmox.com>]

Implements the necessary API for allowing single file restore via the PVE web
GUI.

This requires some adaptations of the HTTP server, to allow data streaming
without buffering - otherwise bigger restores would a) use up too much memory b)
get slowed down by the pvedaemon->pveproxy->client return path. Instead, we
transfer the data via a temporary FIFO.

Known issues/further work:
* restore VMs are not shown or stopped, they always run until timeout. Ideas
  would be to stop them when a user closes the restore window (but what if
  another user/tab/... is using the VM too?), or start a worker task for them
  (how to detect new VMs? parse proxmox-file-restore status before and after
  command?). Thoughts appreciated :)
* restarting the daemon or proxy marks the worker as failed and correctly
  stops it, but the browser says the download is OK - just with not enough data.
  Not the best experience, but unsure on how to fix this. Chunked encoding
  maybe, and terminate with an invalid chunk in case of error/abort?


v2:
* attach widget-toolkit patches, forgot them in v1
* drop patch "PBSClient: allow different command execution callback"
* drop applied patches, rebase
* nit cleanups from Fabian's preliminary review (thanks!)
  * includes API permission changes to keep them uniform for pve-storage
* fixups for Dominic's testing (thanks!)
* now supports encrypted CT and VM backups
