### CopyObject(bucketName, objectName, objectSource string, conditions CopyConditions) error
### CopyObject(dst DestinationInfo, src SourceInfo) error
Copy a source object into a new object with the provided name in the provided bucket.
Create or replace an object through server-side copying of an existing object. It supports conditional copying, copying a part of an object and server-side encryption of destination and decryption of source. See the `SourceInfo` and `DestinationInfo` types for further details.
To copy multiple source objects into a single destination object see the `ComposeObject` API.

The `sftp` package provides support for file system operations on remote ssh servers using the SFTP subsystem.
The `sftp` package provides support for file system operations on remote ssh
servers using the SFTP subsystem. It also implements an SFTP server for serving
files from the filesystem.

* There is way too much duplication in the Client methods. If there was an unmarshal(interface{}) method this would reduce a heap of the duplication.

contributing
------------
We welcome pull requests, bug fixes and issue reports.
Before proposing a large change, first please discuss your change by raising an issue.
Before proposing a large change, first please discuss your change by raising an
issue.
For API/code bugs, please include a small, self contained code example to
reproduce the issue. For pull requests, remember test coverage.
We try to handle issues and pull requests with a 0 open philosophy. That means
we will try to address the submission as soon as possible and will work toward
a resolution. If progress can no longer be made (eg. unreproducible bug) or
stops (eg. unresponsive submitter), we will close the bug.
Thanks.

# Request Based SFTP API
The request based API allows for custom backends in a way similar to the http
package. In order to create a backend you need to implement 4 handler
interfaces; one for reading, one for writing, one for misc commands and one for
listing files. Each has 1 required method and in each case those methods take
the Request as the only parameter and they each return something different.
These 4 interfaces are enough to handle all the SFTP traffic in a simplified
manner.
The Request structure has 5 public fields which you will deal with.
- Method (string) - string name of incoming call
- Filepath (string) - path of file to act on
- Attrs ([]byte) - byte string of file attribute data
- Target (string) - target path for renames and sym-links
Below are the methods and a brief description of what they need to do.
### Fileread(*Request) (io.Reader, error)
Handler for "Get" method and returns an io.Reader for the file which the server
then sends to the client.
### Filewrite(*Request) (io.Writer, error)
Handler for "Put" method and returns an io.Writer for the file which the server
then writes the uploaded file to.
### Filecmd(*Request) error
Handles "SetStat", "Rename", "Rmdir", "Mkdir" and "Symlink" methods. Makes the
appropriate changes and returns nil for success or an filesystem like error
(eg. os.ErrNotExist).
### Fileinfo(*Request) ([]os.FileInfo, error)
Handles "List", "Stat", "Readlink" methods. Gathers/creates FileInfo structs
with the data on the files and returns in a list (list of 1 for Stat and
Readlink).
## TODO
- Add support for API users to see trace/debugging info of what is going on
inside SFTP server.
- Consider adding support for SFTP file append only mode.
