|
|||
* `.RequestHandler.redirect` no longer silently strips control characters
|
||||
and whitespace. It is now an error to pass control characters, newlines
|
||||
or tabs.
|
||||
* `.StaticFileHandler` has been reorganized internally and now has additional
|
||||
extension points that can be overridden in subclasses.
|
||||
* `.StaticFileHandler` now supports HTTP ``Range`` requests.
|
||||
`.StaticFileHandler` is still not suitable for files too large to
|
||||
comfortably fit in memory, but ``Range`` support is necessary in some
|
||||
browsers to enable seeking of HTML5 audio and video.
|
||||
* `.StaticFileHandler` now uses longer hashes by default, and uses the same
|
||||
hashes for ``Etag`` as it does for versioned urls.
|
||||
* `.StaticFileHandler.make_static_url` and `.RequestHandler.static_url`
|
||||
now have an additional keyword argument ``include_version`` to suppress
|
||||
the url versioning.
|
||||
* `.StaticFileHandler` now reads its file in chunks, which will reduce
|
||||
memory fragmentation.
|
||||
* Fixed a case where errors in ``SSLIOStream.connect`` (and
|
||||
``SimpleAsyncHTTPClient``) were not being reported correctly.
|
||||
* `.Resolver` now has a `~.Resolver.close` method.
|
||||
* Fixed a potential memory leak with long chains of `tornado.gen` coroutines.
|
||||
* ``curl_httpclient`` now supports the ``PATCH`` and ``OPTIONS`` methods
|
||||
without the use of ``allow_nonstandard_methods=True``.
