Used chunks are marked in phase1 of the garbage collection process by
using the atime property. Each used chunk gets touched so that the atime
gets updated (if older than 24h, see relatime).
Should there ever be a situation in which the phase1 in the GC run needs
a very long time to finish, it could happen that the grace period
calculated in phase2 is not long enough and thus the marking of the
chunks (atime) becomes invalid. This would result in the removal of
needed chunks.
Even though the likelyhood of this happening is very low, using the
timestamp from right before phase1 is started, to calculate the grace
period in phase2 should avoid this situation.

Multiple backups within one backup group don't really make sense, but
break all sorts of guarantees (e.g. a second backup started after a
first would use a "known-chunks" list from the previous unfinished one,
which would be empty - but using the list from the last finished one is
not a fix either, as that one could be deleted or pruned once the first
simultaneous backup is finished).
Fix it by only allowing one backup per backup group at one time. This is
done via a flock on the backup group directory, thus remaining intact
even after a reload.
Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
To prevent a race with a background GC operation, do not allow deletion
of backups who's index might currently be referenced as the "known chunk
list" for successive backups. Otherwise the GC could delete chunks it
thinks are no longer referenced, while at the same time telling the
client that it doesn't need to upload said chunks because they already
exist.
Additionally, prevent deletion of whole backup groups, if there are
snapshots contained that appear to be currently in-progress. This is
currently unlikely to trigger, as that function is only used for sync
jobs, but it's a useful safeguard either way.
Deleting a single snapshot has a 'force' parameter, which is necessary
to allow deleting incomplete snapshots on an aborted backup. Pruning
also sets force=true to avoid the check, since it calculates which
snapshots to keep on its own.
To avoid code duplication, the is_finished method is factored out.

traverse into. As the GC list images is done as backup:backup user
walkdir gets an error.
We cannot ignore just all permission errors, as they could lead to
missing some backup indexes and thus possibly sweeping more chunks
than desired. While *normally* that should not happen through our

datastore from old to new server and got the permission wrong.

via copy_from_slice which is not unsafe

for now mostly copy/paste from nodes/nodename/tasks
(without the parameters)
but we should replace the 'read_task_list' with a method
that gives us the tasks since some timestamp
so that we can get a longer list of tasks than for the node
(we could of course embed this then in the nodes/node/task api call and
remove this again as long as the api is not stable)

The download methods used to take the destination by value
and return them again, since this was required when using
combinators before we had `async fn`.
But this is just an ugly left-over now.

there is now a 'extract_cached_data' which just returns

a list of fields to the correct serde value
this way we do not have to create a serde value in rrd/cache.rs

if the last sync job is too far in the past (or there was none at all
for now) we run it at the next iteration, so we want to show that

then in the frontend, we check if the next_run is < now and show 'pending'

two things were wrong here:
* the range (x..y) does not include y, so the range
(day_num+1..6) goes from (day_num+1) to 5 (but sunday is 6)
* WeekDays.bits() does not return the 'day_num' of that day, but
the bit value (e.g. 64 for SUNDAY) but was treated as the index of
the day of the week
to fix this, we drop the map to WeekDays and use the 'indices'
directly

If one executes a client command like
# proxmox-backup-client files <snapshot> --repository ...
the files shown have already the '.fidx' or '.blob' file ending, so
if a user would just copy paste that one the client would always add
.blob, and the server would not find that file.
So avoid adding file endings if it is already a known OK one.

when starting a new task, we do two things to keep track of tasks
(in that order):
* updating the 'active' file with a list of tasks with
'update_active_workers'
* updating the WORKER_TASK_LIST
the second also updates the status of running tasks in the file by
checking if it is still running by checking the WORKER_TASK_LIST
since those two things are not locked, it can happend that
we update the file, and before updating the WORKER_TASK_LIST,
another thread calls update_active_workers and tries to
get the status from the task log, which won't have any data yet
so the status is 'unknown'
(we do not update that status ever, likely for performance reasons,
so we have to fix this here)
by switching the order of the two operations, we make sure that only
tasks reach the 'active' file which are inserted in the WORKER_TASK_LIST
