Returns the port used by the server. A new port is chosen for each test.

Decrement the counter. Returns an awaitable. Block if the counter is zero and wait for a `.release`. The awaitable raises `.TimeoutEr

Put an item into the queue, perhaps waiting until there is room. Returns a Future, which raises `tornado.util.TimeoutError` after a t

Set the given ``value`` as the `Future`'s result, if not cancelled. Avoids ``asyncio.InvalidStateError`` when calling ``set_result()`` on a c

Defines an option in the global namespace. See `OptionParser.define`.

Return an existing logger or nullptr if a logger with such name doesn't exist. example: spdlog::get("my_logger")->info("hello {}", "world");

Performs a GET and HEAD request and returns the GET response. Fails if any ``Content-*`` headers returned by the two requests differ.

Take control of the underlying stream. Returns the underlying `.IOStream` object and stops all further HTTP processing. Intended for

Reset the internal flag to ``False``. Calls to `.wait` will block until `.set` is called.

Returns an iterator to the beginning of the output range.

Cancels a pending timeout. The argument is a handle as returned by `add_timeout`. It is safe to call `remove_timeout` even if the ca

Runs the ``callback`` after ``delay`` seconds have passed. Returns an opaque handle that may be passed to `remove_timeout` to cancel.

Returns ``True`` if the stream has been closed.

Drop all references from the registry

Put an item into the queue without blocking. If no free slot is immediately available, raise `QueueFull`.

Wait for `.notify`. Returns a `.Future` that resolves ``True`` if the condition is notified, or ``False`` after a timeout.
