The socket IPC interfaces still use 'main thread' in a number of
places. This patch changes all such interfaces and documentation
to speak of 'consumer thread' instead.
The consumer thread handles socket creation, destruction, and
data processing for socket IPC. Traditionally this has been
done on the main thread.
This patch extends the socket IPC classes to support arbitrary
consumer threads. The thread is configured when establishing a
connection, and performs all of the above operations until the
socket is closed.
The I/O thread sends and receives data on a file descriptor. This
has traditionally been performed on a single I/O thread.
This patch extends the socket IPC classes to support arbitrary I/O
threads. The thread is configured when a connection is established
and used until the socket gets closed.
Both types, |union sockaddr_any| and |struct sockaddr_storage|, provide
a sockaddr type that can hold any address. The latter is standardized by
POSIX, so we prefer it.
With this patch, stream and listening sockets handle the setup of
accepted sockets internally. Sub-classes of |StreamSocket| don't
have to overload StreamSocket's |GetIO| any longer.
This patch integrates |ConnectionOrientedSocket| into the hierarchy
of socket I/O classes. In future patches, the class can provide
common interfaces and functionality for all connection-oriented
sockets.
The new class |ListenSocket| listens on Unix sockets for incoming
connections. Accepted connections are handed over to a compatible
connection-oriented socket.
