This was knowingly added as unused, since the QIO channel APIs were intended to be providing an general purpose interface that was anticipating future development. On the one hand it hasn't been used in 9 years, but on the other hand removing it makes the API inconsistent since we provide sync+async variants of every API. > > Signed-off-by: Dr. David Alan Gilbert <dave@treblig.org> > --- > include/io/channel-socket.h | 29 -------------------- > io/channel-socket.c | 54 ------------------------------------- > io/trace-events | 1 - > 3 files changed, 84 deletions(-) > > diff --git a/include/io/channel-socket.h b/include/io/channel-socket.h > index ab15577d38..6c858cc6b5 100644 > --- a/include/io/channel-socket.h > +++ b/include/io/channel-socket.h > @@ -182,35 +182,6 @@ int qio_channel_socket_dgram_sync(QIOChannelSocket *ioc, > SocketAddress *remoteAddr, > Error **errp); > > -/** > - * qio_channel_socket_dgram_async: > - * @ioc: the socket channel object > - * @localAddr: the address to local bind address > - * @remoteAddr: the address to remote peer address > - * @callback: the function to invoke on completion > - * @opaque: user data to pass to @callback > - * @destroy: the function to free @opaque > - * @context: the context to run the async task.

Yeh that's fair enough; there's a big variation in approaches to deadcode, some people are absolute on it, some people would rather keep the consistency.

A few areas of QEMU were designed as formal internal infra APIs, effectively as a "library" for QEMU. Mostly in the latter, we might find places where it is better to keep the deadcode, assuming we still like the design of the APIs in question. I guess this is where things like "deadcode" annotations for linters come in handy. So I'll pass on this particular patch. > > Dave > > > > > > > Signed-off-by: Dr. David Alan Gilbert <dave@treblig.org> > > > --- > > > include/io/channel-socket.h | 29 -------------------- > > > io/channel-socket.c | 54 ------------------------------------- > > > io/trace-events | 1 - > > > 3 files changed, 84 deletions(-) > > > > > > diff --git a/include/io/channel-socket.h b/include/io/channel-socket.h > > > index ab15577d38..6c858cc6b5 100644 > > > --- a/include/io/channel-socket.h > > > +++ b/include/io/channel-socket.h > > > @@ -182,35 +182,6 @@ int qio_channel_socket_dgram_sync(QIOChannelSocket *ioc, > > > SocketAddress *remoteAddr, > > > Error **errp); > > > > > > -/** > > > - * qio_channel_socket_dgram_async: > > > - * @ioc: the socket channel object > > > - * @localAddr: the address to local bind address > > > - * @remoteAddr: the address to remote peer address > > > - * @callback: the function to invoke on completion > > > - * @opaque: user data to pass to @callback > > > - * @destroy: the function to free @opaque > > > - * @context: the context to run the async task.
