Before this change the Features() method would return a different Fs
to that the Features() method was called on if the remote was
instantiated on a file.
The practical effect of this is that optional features, eg `rclone
about` wouldn't work properly when called on a file, and likely this
has been causing low level problems for users of these backends for
ages.
Ideally there would be a test for this, but it turns out that this is
really hard, so instead of that all the backends have been converted
to not copy the Fs and a big warning comment inserted for future
readers.
Fixes#2182
The initial work on this was done by Oliver Heyme with updates from
Cnly.
Oliver Heyme:
* Changed to Microsoft graph
* Enable writing
* Added more options for adding a OneDrive Remote
* Better error handling
* Send modDate at create upload session and fix list children
Cnly:
* Simple upload API only supports max 4MB files
* Fix supported hash types for different drive types
* Fix unchecked err

Before this change we were using the ChildCount in the Folder facet to
determine if a directory was empty or not. However this seems to be
unreliable, or updated asynchronously which meant that `rclone rmdir`
sometimes deleted directories that had files in.
This problem was spotted by the integration tests.
Listing the directory instead of relying on the ChildCount fixes the
problem and the integration tests, without changing the cost (one http
transaction).
This unifies the 3 methods of reading config
* command line
* environment variable
* config file
And allows them all to be configured in all places. This is done by
making the []fs.Option in the backend registration be the master
source of what the backend options are.
The backend changes are:
* Use the new configmap.Mapper parameter
* Use configstruct to parse it into an Options struct
* Add all config to []fs.Option including defaults and help
* Remove all uses of pflag
* Remove all uses of config.FileGet
This implementation hopefully can handle all error requests from the
onedrive for business authentication.
I have only tested it with the "domain in unmanaged state" error.
* Implement about for:
* local, crypt, cache, drive, swift, hubic, onedrive, pcloud, dropbox
* Implement `--json` and `---full` flag for `rclone about`
* change About interface to return a Usage structure
* Remove operations.About as it is too thin an interface
* Implement Integration test
Relates to #1138 and #1564
Unfortunately multi part upload can't upload zero length files so
bring back the single part upload for zero length files only.
This was broken when we made all uploads multipart uploads.
Because of a bug in the Onedrive API it will sometime report the wrong
size. If the size is wrong other remotes that depend on the size might
fail. To fix this we overwrite the objects size with the real size
from ContentLength header.
The purpose of this is to make it easier to maintain and eventually to
allow the rclone backends to be re-used in other projects without
having to use the rclone configuration system.
The new code layout is documented in CONTRIBUTING.
