+
+ You do not pass Socket instances to this, but rather Socket types::
+
+ Device(device_type, in_socket_type, out_socket_type)
+
+ For instance::
+
+ dev = Device(zmq.QUEUE, zmq.DEALER, zmq.ROUTER)
+
+ Similar to zmq.device, but socket types instead of sockets themselves are
+ passed, and the sockets are created in the work thread, to avoid issues

+ Parameters
+ ----------
+ device_type : int
+ The 0MQ Device type
+ {in|out}_type : int
+ zmq socket types, to be passed later to context.socket(). e.g.
+ zmq.PUB, zmq.SUB, zmq.REQ. If out_type is < 0, then in_socket is used
+ for both in_socket and out_socket.
+
+ Methods
+ -------
+ bind_{in_out}(iface)
+ passthrough for ``{in|out}_socket.bind(iface)``, to be called in the thread
+ connect_{in_out}(iface)

+
+ Attributes
+ ----------

+ Default is true, because if it is false, the thread will not
+ exit unless it is killed
+ context_factory : callable (class attribute)
+ Function for creating the Context. This will be Context.instance

+"""`StackContext` allows applications to maintain threadlocal-like state
+that follows execution as it moves to other execution contexts.
+
+The motivating examples are to eliminate the need for explicit
+``async_callback`` wrappers (as in `tornado.web.RequestHandler`), and to
+allow some additional context to be kept for logging.
+
+This is slightly magic, but it's an extension of the idea that an
+exception handler is a kind of stack-local state and when that stack
+is suspended and resumed in a new context that state needs to be
+preserved. `StackContext` shifts the burden of restoring that state
+from each call site (e.g. wrapping each `.AsyncHTTPClient` callback
+in ``async_callback``) to the mechanisms that transfer control from
+one context to another (e.g. `.AsyncHTTPClient` itself, `.IOLoop`,
+thread pools, etc).
+
+Example usage::
+
+ @contextlib.contextmanager
+ def die_on_error():
+ try:
+ yield
+ except Exception:
+ logging.error("exception in asynchronous operation",exc_info=True)
+ sys.exit(1)
+
+ with StackContext(die_on_error):
+ # Any exception thrown here *or in callback and its desendents*
+ # will cause the process to exit instead of spinning endlessly
+ # in the ioloop.
+ http_client.fetch(url, callback)
+ ioloop.start()
+
+Most applications shouln't have to work with `StackContext` directly.
+Here are a few rules of thumb for when it's necessary:
+
+* If you're writing an asynchronous library that doesn't rely on a
+ stack_context-aware library like `tornado.ioloop` or `tornado.iostream`
+ (for example, if you're writing a thread pool), use
+ `.stack_context.wrap()` before any asynchronous operations to capture the
+ stack context from where the operation was started.
+
+* If you're writing an asynchronous library that has some shared
+ resources (such as a connection pool), create those shared resources
+ within a ``with stack_context.NullContext():`` block. This will prevent
+ ``StackContexts`` from leaking from one request to another.
+
+* If you want to write something like an exception handler that will
+ persist across asynchronous calls, create a new `StackContext` (or
+ `ExceptionStackContext`), and make your asynchronous calls in a ``with``
+ block that references your `StackContext`.

+ """Utility for fixing CTRL-C events on Windows.
+
+ On Windows, the Python interpreter intercepts CTRL-C events in order to
+ translate them into ``KeyboardInterrupt`` exceptions. It (presumably)
+ does this by setting a flag in its "control control handler" and
+ checking it later at a convenient location in the interpreter.
+
+ However, when the Python interpreter is blocked waiting for the ZMQ
+ poll operation to complete, it must wait for ZMQ's ``select()``
+ operation to complete before translating the CTRL-C event into the
+ ``KeyboardInterrupt`` exception.
+
+ The only way to fix this seems to be to add our own "console control
+ handler" and perform some application-defined operation that will
+ unblock the ZMQ polling operation in order to force ZMQ to pass control
+ back to the Python interpreter.
+
+ This context manager performs all that Windows-y stuff, providing you
+ with a hook that is called when a CTRL-C event is intercepted. This
+ hook allows you to unblock your ZMQ poll operation immediately, which
+ will then result in the expected ``KeyboardInterrupt`` exception.
+
+ Without this context manager, your ZMQ-based application will not
+ respond normally to CTRL-C events on Windows. If a CTRL-C event occurs
+ while blocked on ZMQ socket polling, the translation to a
+ ``KeyboardInterrupt`` exception will be delayed until the I/O completes
+ and control returns to the Python interpreter (this may never happen if
+ you use an infinite timeout).
+
+ A no-op implementation is provided on non-Win32 systems to avoid the
+ application from having to conditionally use it.
+
+ Example usage:
+
+ .. sourcecode:: python
+
+ def stop_my_application():
+ # ...
+
+ with allow_interrupt(stop_my_application):
+ # main polling loop.
+
+ In a typical ZMQ application, you would use the "self pipe trick" to
+ send message to a ``PAIR`` socket in order to interrupt your blocking
+ socket polling operation.
+
+ In a Tornado event loop, you can use the ``IOLoop.stop`` method to
+ unblock your I/O loop.
