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`

Instance Variable | `_realPortNumber` | Undocumented
Instance Variable | `_type` | A string describing the connections which will be created by this port. Normally this is `"TCP"`, since this is a TCP port, but when the TLS implementation re-uses this class it overrides the value with ...

`str` | Undocumented

def connectionLost(self, reason): (source)
from `twisted.internet.interfaces.IFileDescriptor`
overrides `twisted.internet.tcp.Port.connectionLost`

Cleans up the socket.

def startListening(self): (source)
from `twisted.internet.interfaces.IListeningPort`

Parameters
reactor | Undocumented
fd | An integer file descriptor associated with a listening socket. The socket must be in non-blocking mode. Any additional attributes desired, such as FD_CLOEXEC, must also be set already.
