The new class |ListenSocket| listens on Unix sockets for incoming
connections. Accepted connections are handed over to a compatible
connection-oriented socket.
The class |UnixSocketIOBuffer| maintains memory buffers for socket I/O
operations. The actual I/O is still implemented by subclasses, such as
|UnixSocketRawData|.
The data class in |SocketIOSendTask| is now a template parameter, instead
of being hard-coded to |UnixSocketRawData|. The patch also adds soem minor
cleanups to the file.
This patch moves the I/O operations for sending and receiving data
in |SocketIOBase| into |UnixSocketRawData|. This change allows to
add a clean interface to |UnixSocketRawData| and later replace the
class by other implementations.
Calling read on a socket that has been closed for reading by the
peer, read returns 0. The socket is still readable however, so
polling and reading will return constant results of 0 received
bytes.
With this patch, if a socket's peer shuts down reading or if
we reached the EOF, we stop watching the file descriptor for
readability. |SocketIOBase| will detect this case exactly once
and initiate the socket's shutdown.
After successfully sending data, |SocketIOBase::SendPendingData|
deletes the raw data instead of the actual socket-data object. The
behavior is undefined and leads to a segmentation fault.
This patch fixes the bug by deleting the correct object.
This patch cleans up |UnixSocketImpl| and it's file in general. The
patch
- renames |UnixSocketImpl| to |UnixSocketConsumerIO|,
- moves method definitions out of class definition,
- adds const correctness,
- adds MOZ_FINAL to several classes,
- moves task classes to a separate location.
No functional changes are performed.
|SocketIOTask| is a task-class template that holds a reference to
a Socket I/O object. It replaces |UnixSocketImplTask|, which only
supports objects of type |UnixSocketImpl|.
|SocketIOBase| is a base class for Socket I/O classes. It's not a
requirement, but provides a number of helpful methods for common
I/O operations on the I/O thread.
|SocketIODeleteInstanceRunnable| deletes a Socket I/O object on the
main thread. This is required to serialize the close operation of
Socket consumers.
|SocketIORunnable| is a runnable class template that holds a
reference to a arbitrary Socket I/O object. |SocketIORunnable|
replaces |UnixSocketImplRunnable|, which only handles objects of
type |UnixSocketImpl|.
|SocketConsumerBase| handles connection state for |UnixSocketConsumer|
and its derived classes. Implementing classes must override a number of
virtual methods, to handle notifications about changes to the state of
the connection.
