[pbs-devel] [PATCH v2 proxmox-backup 0/3] handle reader client disconnects

[Christian Ebner]

These patches attempt to improve the server side error handling for
reader client disconnects.

During regular operation, the server currently cannot distinguish a
disconnect because of error from a disconnect because of finished
operation. This leaves behind a task in failed state, which is
unexpected and might cause confusion [0].

To improve error handling, follow the approach taken for the backup
writer tasks, letting the client signal it has successfully finished
via an api call and catch the disconnect error for that case.
