This simplifies the implementation of remotes. The only required
interface is now `List` which is a simple one level directory list.
Optionally remotes may implement `ListR` if they have an efficient way
of doing a recursive list.
The ListR interface will be implemented by remotes that can do a
recursive directory listing more efficiently than just recursing
through the directories. These include the bucket based remotes.
This is a fix left over from the v2 conversion. Dropbox ignores the
client modification on an incoming file if it was identical to the
existing file. This change deletes the existing file first before
re-uploading the new one.
If set in the config file, these override the ones configured into the
remote. This enables alternative oauth servers to be used for all
oauth remotes. This can only be altered by editing the config file
for the moment.
* fully write new config file before moving to target location (fixes#1287)
* do not fail if there is no previous config; print temporary config path on failure
* Add options to Put, PutUnchecked and Update for all Fses
* Use these to create HashOption
* Implement this in local
* Pass the option in fs.Copy
This has the effect that we only calculate hashes we need to in the
local Fs which speeds up transfers significantly.
* add support to hashing module
* add dbhashsum to list the hashes
* add support to dropbox module
This means objects up and downloaded to/from Dropbox will have their
hashes checked.
Note after this change local objects are calculating MD5, SHA1 and
DBHASH which is excessive and needs to be fixed.
This makes rclone with encrypted config better suited for use in
pipelines. E.g.:
$ rclone lsl mydrive:Some/Dir | sort -k 4
If the password prompt ("Enter configuration password") is printed to
stdout, it will be swallowed by sort. By printing it to stderr, you
still see the prompt, without sacrificing compatibility with the unix
pipeline.
What was happening is that when Move was implemented as Copy + Delete,
MoveFile was seeing the files didn't need transferring (because they
were identical) then deleted the source.
The fix uses Move instead and patches onedrive to disallow a case
folded identical copy (which errors with 500 error)
