this change adds the depth parameter to listAll and readMetaDataForPath.
this allows recursive calls of these methods with a different depth
header.
Sharepoint won't list files if the depth header is != 0. If that is the
case, it will just return a error 404 although the file exists.
Since it is not possible to determine if a path should be a file or a
directory, rclone has to make a request with depth = 1 first. On success
we are sure that the path is a directory and the listing will work.
If this request returns error 404, the path either doesn't exist or it
is a file.
To be sure, we can try again with depth set to 0. If it still fails, the
path really doesn't exist, else we found our file.
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
Go can't redirect PROPFIND requests properly, it changes the method to
GET, so we disable redirects when reading the metadata and assume the
object does not exist if we receive a redirect.
This is to work-around the qnap redirecting requests for directories
without /.
This enables the use of the SharePoint webdav endpoint provided by
OneDrive for Business or Office365 Education Accounts. It enables
unverified accounts to be accessed with rclone via webdav as it isn't
possible through the normal onedrive backend.
This integrates the https://github.com/hensur/onedrive-cookie-test
package to fetch the required cookies to authorize against the
SharePoint webdav endpoint.
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.
