The fuse code kept adding snapshots to the top-level dir "snapshots". In
addition, snapshots with the same timestamp (same second) were not added
correctly, they will now be suffixed by an incrementing counter, e.g.:
dr-xr-xr-x 1 fd0 users 0 Sep 18 15:01 2016-09-18T15:01:44+02:00
dr-xr-xr-x 1 fd0 users 0 Sep 18 15:01 2016-09-18T15:01:48+02:00
dr-xr-xr-x 1 fd0 users 0 Sep 18 15:01 2016-09-18T15:01:48+02:00-1
Closes #624
This code is introduced to watch for issue #529, in which two users
describe that restic failed encoding a time in a node to JSON with the
error message:
panic: json: error calling MarshalJSON for type *restic.Node: json: error calling MarshalJSON for type time.Time: Time.MarshalJSON: year outside of range [0,9999]
The error message now is:
panic: Marshal: json: error calling MarshalJSON for type *restic.Node: node /home/fd0/shared/work/restic/restic/.git/hooks/applypatch-msg.sample has invalid ModTime year -1: -0001-01-02 03:04:05.000000006 +0053 LMT
This closes #606, which fails because several snapshots are created with
exactly the same timestamp, and the code checks that for each snapshot
there is a dir in the fuse mount. This fails for colliding timestamps,
so we now add a suffix "-1", "-2" etc for each duplicate timestamp.
Sample:
counting files in repo
building new index for repo
[0:00] 100.00% 22 / 22 packs
repository contains 22 packs (1377 blobs) with 90.610 MiB bytes
processed 1377 blobs: 0 duplicate blobs, 0B duplicate
load all snapshots
find data that is still in use for 1 snapshots
[0:00] 100.00% 1 / 1 snapshots
found 409 of 1377 data blobs still in use, removing 968 blobs
will delete 10 packs and rewrite 10 packs, this frees 64.232 MiB
creating new index
[0:00] 100.00% 7 / 7 packs
saved new index as df467c6e
done
