Add a 'numeric' flag to the InetSocketAddress struct to allow the
caller to indicate that DNS should be skipped for the host/port
fields. This is useful if the caller knows the address is already
numeric and wants to guarantee no (potentially blocking) DNS
lookups are attempted.

Incrementing the reference in qio_task_get_source is
not necessary, since we're not running concurrently
with any other code touching the QIOTask. This
minimizes chances of further memory leaks.

The GDestroyNotify parameter is already a pointer, so does
not need a '*' suffix on the type.

Currently there is no data associated with a successful
task completion. This adds an opaque pointer to the task
to store an arbitrary result.

Currently when a task fails, the error is never explicitly
associated with the task object, it is just passed along
through the completion callback. This adds the ability to
explicitly associate an error with the task.

Currently the QIOTaskFunc signature takes an Object * for
the source, and an Error * for any error. We also need to
be able to provide a result pointer. Rather than continue
to add parameters to QIOTaskFunc, remove the existing
ones and simply pass the QIOTask object instead. This
has methods to access all the other data items required
in the callback impl.

From: Daniel P. Berrange @ 2017-01-23 14:26 UTC (permalink / raw)
To: qemu-devel; +Cc: Peter Maydell, Daniel P. Berrange
Now that task objects have a directly associated error,
there's no need for an an Error **errp parameter to
the QIOTask thread worker function. It already has a
QIOTask object, so can directly set the error on it.

To: qemu-devel; +Cc: Peter Maydell, Daniel P. Berrange
Currently DNS resolution is done automatically as part
of the creation of a QIOChannelSocket object instance.
This works ok for network clients where you just end
up a single network socket, but for servers, the results
of DNS resolution may require creation of multiple
sockets.
Introducing a DNS resolver API allows DNS resolution
to be separated from the socket object creation. This
will make it practical to create multiple QIOChannelSocket
instances for servers.

OSX does have pthread_once(), but you need to actually include
pthread.h (either directly or more likely via qemu/thread.h)
to get it.

Of course pthread_once Is not available on Win32 at all. What I
should have used was GOnce which is portable from glib, since
QEMU's thread APIs don't provide any once-control wrappers.
