SFTPServerzå
Server-side SFTP subsystem support. Since this is a `.SubsystemHandler`,
it can be (and is meant to be) set as the handler for ``"sftp"`` requests.
Use `.Transport.set_subsystem_handler` to activate this class.

dS )a
The constructor for SFTPServer is meant to be called from within the
`.Transport` as a subsystem handler. ``server`` and any additional
parameters or keyword parameters are passed from the original call to
`.Transport.set_subsystem_handler`.
:param .Channel channel: channel passed from the `.Transport`.
:param str name: name of the requested subsystem.
:param .ServerInterface server:
the server object associated with this channel and subsystem
:param sftp_si:
a subclass of `.SFTPServerInterface` to use for handling individual
requests.

Convert an errno value (as from an ``OSError`` or ``IOError``) into a
standard SFTP result code. This is a convenience function for trapping
exceptions in server code and returning an appropriate result.
:param int e: an errno code, as from ``OSError.errno``.
:return: an `int` SFTP error code like ``SFTP_NO_SUCH_FILE``.

Change a file's attributes on the local filesystem. The contents of
``attr`` are used to change the permissions, owner, group ownership,
and/or modification & access time of the file, depending on which
attributes are present in ``attr``.
This is meant to be a handy helper function for translating SFTP file
requests into local file operations.
:param str filename:
name of the file to alter (should usually be an absolute path).
:param .SFTPAttributes attr: attributes to change.
