Uses b2_list_file_versions to retrieve all file versions, and returns
the one that was active at the specified time
This is especially useful in combination with other backup tools, such
as restic, which may use rclone as a backend.
Similar to fs.Duration but parses into a timestamp instead
Supports parsing from:
* Any of the date formats in parseTimeDates
* A time.Duration offset from now
* parseDurationSuffixes offset from now
Jottacloud have several different apis and endpoints using a mix of different
timestamp formats. In existing code the list operation (after the recent liststream
implementation) uses format from golang's time.RFC3339 constant. Uploads (using the
allocate api) uses format from a hard coded constant with value identical to golang's
time.RFC3339. And then we have the classic JFS time format, which is similar to RFC3339
but not identical, using a different constant. Also the naming is a bit confusing,
since the term api is used both as a generic term and also as a reference to the
newer format used in the api subdomain where the allocate endpoint is located.
This commit refactors these things a bit.
Now using the utility function for deduplication that was newly implemented to
fix an issue with server-side copy. This function uses the original, and generic,
"jfs" api (and its "cphash" feature), instead of the newer "allocate" api dedicated
for uploads. Both apis support similar deduplication functionaly that we rely on for
the SetModTime operation. One advantage of using the jfs variant is that the allocate
api is specialized for uploads, an initial request performs modtime-only changes and
deduplication if possible but if not possible it creates an incomplete file revision
and returns a special url to be used with a following request to upload missing content.
In the SetModTime function we only sent the first request, using metadata from existing
remote file but different timestamps, which lead to a modtime-only change. If, for some
reason, this should fail it would leave the incomplete revision behind. Probably not
a problem, but the jfs implementation used with this commit is simpler and
a more "standalone" request which either succeeds or fails without expecting additional
requests.
A strange feature (probably bug) in the api used by the server-side copy implementation
in Jottacloud backend is that if the destination file is in trash, the copy request
succeeds but the destination will still be in trash! When this situation occurs in
rclone, the copy command will fail with "Failed to copy: object not found" because
rclone verifies that the file info in the response from the copy request is valid,
and since it is marked as deleted it is treated as invalid.
This commit works around this problem by looking for this situation in the response
from the copy operation, and send an additional request to a built-in deduplication
endpoint that will restore the file from trash.
Fixes#6112
Some backends may not provide size for all objects, and instead
return -1. Existing version included these in directory sums,
with strange results. With this commit rclone ncdu will consider
negative sizes as zero, but add a new prefix flag '~' with a
description that indicates the shown size is inaccurate.
Fixes#6084
In this commit
f4c40bf79d mount: add --devname to set the device name sent to FUSE for mount display
The --devname parameter was added. However it was soon noticed that
attempting to mount via the rc gave this error:
mount helper error: fusermount: unknown option 'fsname'
mount FAILED: fusermount: exit status 1
This was because the DeviceName (and VolumeName) parameter was never
being initialised when the mount was called via the rc.
The fix for this was to refactor the rc interface so it called the
same Mount method as the command line mount which initialised the
DeviceName and VolumeName parameters properly.
This also fixes the cmd/mount tests which were breaking in the same
way but since they aren't normally run on the CI we didn't notice.
Fixes#6044
The existing code in rclone set the value "offline_access+openid",
when encoded in body it will become "offline_access%2Bopenid". I think
this is wrong. Probably an artifact of "double urlencoding" mixup -
either in rclone or in the jottacloud cli tool version it was sniffed
from? It does work, though. The token received will have scopes "email
offline_access" in it, and the same is true if I change to only
sending "offline_access" as scope.
If a proper space delimited list of "offline_access openid"
is used in the request, the response also includes openid scope:
"openid email offline_access". I think this is more correct and this
patch implements this.
See: #6107
Adds a configuration option to the GCS backend to allow skipping the
check if a bucket exists before copying an object to it, much like
f406dbb added for S3.
When this code was originally implemented os.UserCacheDir wasn't
public so this used a copy of the code. This commit replaces that now
out of date copy with a call to the now public stdlib function.
