Adding the option to load the storage url and the auth key
from the environment when you have an alternate authorization,
external to rclone, and you need to use it (e.g. because
it's not yet supported by the swift go library)
Allowing to get alternate authentication from config file,
and using proper way (c.Authenticated()) to know if it's authenticated.
Updated docs as well
Avoids blindly trying to create the segments container, which can fail if the
authentication credentials don't allow container creates or updates.
Fixes#1769
This was caused by rclone adjusting the object names. If the last
object in the listing page happened to be a directory, rclone would
remove the / which caused the next page to start in the wrong place.
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.
* 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.
Optional interfaces are becoming more important in rclone,
--track-renames and --backup-dir both rely on them.
Up to this point rclone has used interface upgrades to define optional
behaviour on Fs objects. However when one Fs object wraps another it
is very difficult for this scheme to work accurately. rclone has
relied on specific error messages being returned when the interface
isn't supported - this is unsatisfactory because it means you have to
call the interface to see whether it is supported.
This change enables accurate detection of optional interfaces by use
of a Features struct as returned by an obligatory Fs.Features()
method. The Features struct contains flags and function pointers
which can be tested against nil to see whether they can be used.
As a result crypt and hubic can accurately reflect the capabilities of
the underlying Fs they are wrapping.
These are set in the form RCLONE_CONFIG_remote_option where remote is
the uppercased remote name and option is the uppercased config file
option name. Note that RCLONE_CONFIG_remote_TYPE must be set if
defining a new remote.

With Keystone V3 both users and projects (a.k.a. tenants) can belong
to different domains. This change allow specifying different domains
for the user and the project.
If remote:path points to a file make NewFs return a sentinel error
fs.ErrorIsFile and an Fs which points to the parent.
Use this to remove the LimitedFs and just add this file to the
--files-from list.
This means that server side operations can be used also.
Fixes#518Fixes#545
Gives more accurate error propagation, control of depth of recursion
and short circuit recursion where possible.
Most of the the heavy lifting is done in the "fs" package, making file
system implementations a bit simpler.
This commit contains some code originally by Klaus Post.
