twisted.protocols.ftp.FTPFileListProtocol : API documentation

Parser for standard FTP file listings

This is the evil required to match:

   -rw-r--r--   1 root     other        531 Jan 29 03:26 README

If you need different evil for a wacky FTP server, you can override either fileLinePattern or parseDirectoryLine().

It populates the instance attribute self.files, which is a list containing dicts with the following keys (examples from the above line):

filetype: e.g. 'd' for directories, or '-' for an ordinary file
perms: e.g. 'rw-r--r--'
nlinks: e.g. 1
owner: e.g. 'root'
group: e.g. 'other'
size: e.g. 531
date: e.g. 'Jan 29 03:26'
filename: e.g. 'README'
linktarget: e.g. 'some/file'

Note that the 'date' value will be formatted differently depending on the date. Check http://cr.yp.to/ftp.html if you really want to try to parse it.

It also matches the following:

   -rw-r--r--   1 root     other        531 Jan 29 03:26 I HAVE\ SPACE
      - filename:   e.g. 'I HAVE SPACE'

   -rw-r--r--   1 root     other        531 Jan 29 03:26 LINK -> TARGET
      - filename:   e.g. 'LINK'
      - linktarget: e.g. 'TARGET'

   -rw-r--r--   1 root     other        531 Jan 29 03:26 N S -> L S
      - filename:   e.g. 'N S'
      - linktarget: e.g. 'L S'

Instance Variable	files	list of dicts describing the files in this listing
Method	__init__	Undocumented
Method	lineReceived	Override this for when each line is received.
Method	parseDirectoryLine	Return a dictionary of fields, or None if line cannot be parsed.
Method	addFile	Append file information dictionary to the list of known files.
Method	unknownLine	Deal with received lines which could not be parsed as file information.

Inherited from LineReceiver:

Class Variable	delimiter	The line-ending delimiter to use. By default this is `b'\r\n'`.
Class Variable	MAX_LENGTH	The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.
Method	clearLineBuffer	Clear buffered data.
Method	dataReceived	Protocol.dataReceived. Translates bytes into lines, and calls lineReceived (or rawDataReceived, depending on mode.)
Method	setLineMode	Sets the line-mode of this receiver.
Method	setRawMode	Sets the raw mode of this receiver. Further data received will be sent to rawDataReceived rather than lineReceived.
Method	rawDataReceived	Override this for when raw data is received.
Method	sendLine	Sends a line to the other end of the connection.
Method	lineLengthExceeded	Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.

Inherited from Protocol (via LineReceiver):

Method	logPrefix	Return a prefix matching the class name, to identify log messages related to this protocol instance.
Method	connectionLost	Called when the connection is shut down.

Inherited from BaseProtocol (via LineReceiver, Protocol):

Method	makeConnection	Make a connection to a transport and a server.
Method	connectionMade	Called when a connection is made.

Inherited from _PauseableMixin (via LineReceiver):

Method	pauseProducing	Undocumented
Method	resumeProducing	Undocumented
Method	stopProducing	Undocumented

def __init__(self): (source)

Undocumented

def lineReceived(self, line): (source)

overrides twisted.protocols.basic.LineReceiver.lineReceived

Override this for when each line is received.

Parameters line The line which was received with the delimiter removed. (type: bytes)

def parseDirectoryLine(self, line): (source)

Return a dictionary of fields, or None if line cannot be parsed.

Parameters	line	line of text expected to contain a directory entry (type: str)
Returns	dict

def addFile(self, info): (source)

Append file information dictionary to the list of known files.

Subclasses can override or extend this method to handle file information differently without affecting the parsing of data from the server.

Parameters info dictionary containing the parsed representation of the file information (type: dict)

def unknownLine(self, line): (source)

Deal with received lines which could not be parsed as file information.

Subclasses can override this to perform any special processing needed.

Parameters line unparsable line as received (type: str)
