Various asynchronous TCP/IP classes.
End users shouldn't use this module directly - use the reactor APIs instead.
Class | Connection | Superclass of all socket-based FileDescriptors. |
Class | BaseClient | A base class for client TCP (and similar) sockets. |
Class | Client | A transport for a TCP protocol; either TCPv4 or TCPv6. |
Class | Server | Serverside socket-stream connection class. |
Class | Port | A TCP server port, listening for connections. |
Class | Connector | A Connector
provides of twisted.internet.interfaces.IConnector
for all POSIX-style reactors. |
Class | _TLSConnectionMixin | Undocumented |
Class | _TLSClientMixin | Undocumented |
Class | _TLSServerMixin | Undocumented |
Function | _getrealname | No summary |
Function | _getpeername | See _getrealname . |
Function | _getsockname | See _getrealname . |
Class | _SocketCloser | |
Class | _AbortingMixin | Common implementation of abortConnection . |
Class | _BaseBaseClient | Code shared with other (non-POSIX) reactors for management of general outgoing connections. |
Function | _resolveIPv6 | Resolve an IPv6 literal into an IPv6 address. |
Class | _BaseTCPClient | Code shared with other (non-POSIX) reactors for management of outgoing TCP connections (both TCPv4 and TCPv6). |
Interface | _IFileDescriptorReservation | No summary |
Class | _FileDescriptorReservation | _IFileDescriptorReservation
implementation. |
Class | _NullFileDescriptorReservation | A null implementation of _IFileDescriptorReservation . |
Class | _BuffersLogs | A context manager that buffers any log events until after its block exits. |
Function | _accept | Return a generator that yields client sockets from the provided listening socket until there are none left or an unrecoverable error occurs. |
Return a 2-tuple of socket IP and port for IPv4 and a 4-tuple of socket IP, port, flowInfo, and scopeID for IPv6. For IPv6, it returns the interface portion (the part after the %) as a part of the IPv6 address, which Python 3.7+ does not include.
Parameters | addr | A 2-tuple for IPv4 information or a 4-tuple for IPv6 information. |
Resolve an IPv6 literal into an IPv6 address.
This is necessary to resolve any embedded scope identifiers to the
relevant sin6_scope_id
for use with
socket.connect()
, socket.listen()
, or
socket.bind()
; see RFC 3493 for
more information.
Parameters | ip | An IPv6 address literal. (type: str ) |
port | A port number. (type: int ) | |
Returns | a 4-tuple of (host, port, flow, scope) , suitable for use as an
IPv6 address. | |
Raises | socket.gaierror | if either the IP or port is not numeric as it should be. |
Return a generator that yields client sockets from the provided listening socket until there are none left or an unrecoverable error occurs.
Parameters | logger | A logger to which accept -related events will be logged. This
should not log to arbitrary observers that might open a file descriptor to
avoid claiming the EMFILE file descriptor on UNIX-like
systems. (type: Logger ) |
accepts | An iterable iterated over to limit the number consecutive
accept s. (type: An iterable.) | |
listener | The listening socket. (type: socket.socket ) | |
reservedFD | A reserved file descriptor that can be used to recover from
EMFILE on UNIX-like systems. (type: _IFileDescriptorReservation ) | |
Returns | A generator that yields (socket, addr) tuples from socket.socket.accept |
