tornado.platform.twisted — Bridges between Twisted and Tornado¶
Deprecated since version 6.0: This module is no longer recommended for new code. Instead of using
direct integration between Tornado and Twisted, new applications should
rely on the integration with
asyncio provided by both packages.
Importing this module has the side effect of registering Twisted’s
class with Tornado’s
@gen.coroutine so that
Deferred objects can be
yield in coroutines using this decorator (importing this module has
no effect on native coroutines using
AsyncioSelectorReactoras the default Twisted reactor.
Deprecated since version 5.1: This function is provided for backwards compatibility; code that does not require compatibility with older versions of Tornado should use
Changed in version 6.0.3: In Tornado 5.x and before, this function installed a reactor based on the Tornado
IOLoop. When that reactor implementation was removed in Tornado 6.0.0, this function was removed as well. It was restored in Tornado 6.0.3 using the
Twisted DNS resolver¶
- class tornado.platform.twisted.TwistedResolver¶
Twisted-based asynchronous resolver.
This is a non-blocking and non-threaded resolver. It is recommended only when threads cannot be used, since it has limitations compared to the standard
DefaultExecutorResolver. Specifically, it returns at most one result, and arguments other than
familyare ignored. It may fail to resolve when
Requires Twisted 12.1 or newer.
Changed in version 5.0: The
io_loopargument (deprecated since version 4.1) has been removed.
Deprecated since version 6.2: This class is deprecated and will be removed in Tornado 7.0. Use the default thread-based resolver instead.
