def toSegments(cwd, path): (source)
Normalize a path, as represented by a list of strings each representing one segment of the path.
def errnoToFailure(e, path): (source)
Map OSError and IOError to standard FTP errors.
def _isGlobbingExpression(segments=None): (source)
Helper for checking if a FTPShell `segments` contains a wildcard Unix expression.

Only filename globbing is supported. This means that wildcards can only be presents in the last element of `segments`.

ParameterssegmentsList of path elements as used by the FTP server protocol. (type: list)
ReturnsTrue if `segments` contains a globbing expression. (type: Boolean)
def debugDeferred(self, *_): (source)
Undocumented
def _getgroups(uid): (source)
Return the primary and supplementary groups for the given UID.
def _testPermissions(uid, gid, spath, mode='r'): (source)
checks to see if uid has proper permissions to access path with mode
Parametersuidnumeric user id (type: int)
gidnumeric group id (type: int)
spaththe path on the server to test (type: str)
mode'r' or 'w' (read or write) (type: str)
ReturnsTrue if the given credentials have the specified form of access to the given path (type: bool)
def decodeHostPort(line): (source)
Decode an FTP response specifying a host and port.
Returnsa 2-tuple of (host, port).
def encodeHostPort(host, port): (source)
Undocumented
def _unwrapFirstError(failure): (source)
Undocumented
def parsePWDResponse(response): (source)
Returns the path from a response to a PWD command.

Responses typically look like:

   257 "/home/andrew" is current directory.

For this example, I will return '/home/andrew'.

If I can't find the path, I return None.
