search in docstrings

Search bar offers the following options:

- Term presence. The below example searches for documents that must contain “foo”, might contain “bar” and must not contain “baz”: `+foo bar -baz`
- Wildcards. The below example searches for documents with words beginning with “foo”: `foo*`
- Search in specific fields. The following search matches all objects in "twisted.mail" that matches “search”: `+qname:twisted.mail.* +search`

  Possible fields: 'name', 'qname' (fully qualified name), 'docstring', and 'kind'. Last two fields are only applicable if "search in docstrings" is enabled.

- Fuzzy matches. The following search matches all documents that have a word within 1 edit distance of “foo”: `foo~1`

class documentation

`class IdentServer(basic.LineOnlyReceiver): (source)`

View In Hierarchy

The Identification Protocol (a.k.a., "ident", a.k.a., "the Ident Protocol") provides a means to determine the identity of a user of a particular TCP connection. Given a TCP port number pair, it returns a character string which identifies the owner of that connection on the server's system.

Server authors should subclass this class and override the lookup method. The default implementation returns an UNKNOWN-ERROR response for every query.

Method | `invalidQuery` | Undocumented
Method | `lineReceived` | Override this for when each line is received.
Method | `lookup` | Lookup user information about the specified address pair.
Method | `validQuery` | Called when a valid query is received to look up and deliver the response.
Method | `_cbLookup` | Undocumented
Method | `_ebLookup` | Undocumented

Inherited from `LineOnlyReceiver`:

Method | `dataReceived` | Translates bytes into lines, and calls lineReceived.
Method | `lineLengthExceeded` | Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.
Method | `sendLine` | Sends a line to the other end of the connection.
Constant | `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.
Class Variable | `delimiter` | The line-ending delimiter to use. By default this is `b'\r\n'`.
Instance Variable | `_buffer` | Undocumented

Inherited from `Protocol` (via `LineOnlyReceiver`):

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

Inherited from `BaseProtocol` (via `LineOnlyReceiver`, `Protocol`):

Method | `connectionMade` | Called when a connection is made.
Method | `makeConnection` | Make a connection to a transport and a server.
Instance Variable | `connected` | Undocumented
Instance Variable | `transport` | Undocumented

def invalidQuery(self): (source)

Undocumented

def lineReceived(self, line): (source)
overrides `twisted.protocols.basic.LineOnlyReceiver.lineReceived`

Override this for when each line is received.

Parameters
line:`bytes` | The line which was received with the delimiter removed.

def lookup(self, serverAddress, clientAddress): (source)

Lookup user information about the specified address pair.

Return value should be a two-tuple of system name and username. Acceptable values for the system name may be found online at:

        U{http://www.iana.org/assignments/operating-system-names}

This method may also raise any IdentError subclass (or IdentError itself) to indicate user information will not be provided for the given query.

A Deferred may also be returned.

Parameters
serverAddress | A two-tuple representing the server endpoint of the address being queried. The first element is a string holding a dotted-quad IP address. The second element is an integer representing the port.
clientAddress | Like serverAddress, but represents the client endpoint of the address being queried.

def validQuery(self, portOnServer, portOnClient): (source)

Called when a valid query is received to look up and deliver the response.

Parameters
portOnServer | The server port from the query.
portOnClient | The client port from the query.
