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
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
This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
This changes the interface to NewObject so that if NewObject is called
on a directory then it should return fs.ErrorIsDir if possible without
doing any extra work, otherwise fs.ErrorObjectNotFound.
Tested on integration test server with:
go run integration-test.go -tests backend -run TestIntegration/FsMkdir/FsPutFiles/FsNewObjectDir -branch fix-stat -maxtries 1
This is a very large change which turns the post Config function in
backends into a state based call and response system so that
alternative user interfaces can be added.
The existing config logic has been converted, but it is quite
complicated and folloup commits will likely be needed to fix it!
Follow up commits will add a command line and API based way of using
this configuration system.
This change checks the context whenever rclone might retry, and
doesn't retry if the current context has an error.
This fixes the pathological behaviour of `--max-duration` refusing to
exit because all the context deadline exceeded errors were being
retried.
This unfortunately meant changing the shouldRetry logic in every
backend and doing a lot of context propagation.
See: https://forum.rclone.org/t/add-flag-to-exit-immediately-when-max-duration-reached/22723
This is done by making fs.Config private and attaching it to the
context instead.
The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.
This adds a context.Context parameter to NewFs and related calls.
This is necessary as part of reading config from the context -
backends need to be able to read the global config.
- add a directory to the optional Purge interface
- fix up all the backends
- add an additional integration test to test for the feature
- use the new feature in operations.Purge
Many of the backends had been prepared in advance for this so the
change was trivial for them.
This adds expire and unlink fields to the PublicLink interface.
This fixes up the affected backends and removes unlink parameters
where they are present.
