Change Logs

* Fri Oct 13 2017
- update to version 1.1.0:
  * Features
    + Waitress now has a __main__ and thus may be called with "python
  - mwaitress"
  * Bugfixes
    + Waitress no longer allows lowercase HTTP verbs. This change was
    made to fall in line with most HTTP servers. See
    + When receiving non-ascii bytes in the request URL, waitress will
    no longer abruptly close the connection, instead returning a 400
    Bad Request. See and
* Mon May 01 2017
- Update to 1.0.2
  * Python 3.6 is now officially supported in Waitress
  * Add a work-around for libc issue on Linux not following the
    documented standards. If getnameinfo() fails because of DNS not
    being available it should return the IP address instead of the
    reverse DNS entry, however instead getnameinfo() raises. We
    catch this, and ask getnameinfo() for the same information
    again, explicitly asking for IP address instead of reverse
    DNS hostname.
- Implement single-spec version.
- Fix source URL.
* Tue Nov 15 2016
- update to 1.0.1:
  - IPv6 support on Windows was broken due to missing constants in the socket
    module. This has been resolved by setting the constants on Windows if they
    are missing. See
  - A ValueError was raised on Windows when passing a string for the port, on
    Windows in Python 2 using service names instead of port numbers doesn't work
    with `getaddrinfo`. This has been resolved by attempting to convert the port
    number to an integer, if that fails a ValueError will be raised. See
  - Removed `AI_ADDRCONFIG` from the call to `getaddrinfo`, this resolves an
    issue whereby `getaddrinfo` wouldn't return any addresses to `bind` to on
    hosts where there is no internet connection but localhost is requested to be
    bound to. See for more
- disable tests. need network access.
* Fri May 20 2016
- update to 0.9.0:
  * Security/Protections
  - Building on the changes made in pull request 117, add in checking for line
    feed/carriage return HTTP Response Splitting in the status line, as well as
    the key of a header. See and
  - Waitress will no longer accept headers or status lines with
    newline/carriage returns in them, thereby disallowing HTTP Response
  * Bugfixes
  - FileBasedBuffer and more important ReadOnlyFileBasedBuffer no longer report
    False when tested with bool(), instead always returning True, and becoming
    more iterator like.
  - Call prune() on the output buffer at the end of a request so that it doesn't
    continue to grow without bounds.
* Fri Dec 12 2014
- update to 0.8.9:
  - Fix tests under Windows.  NB: to run tests under Windows, you cannot run
    " test" or " nosetests".  Instead you must run ``python.exe
  - c "import nose; nose.main()"``.  If you try to run the tests using the
    normal method under Windows, each subprocess created by the test suite will
    attempt to run the test suite again.  See for more information.
  - Give the WSGI app_iter generated when ``wsgi.file_wrapper`` is used
    (ReadOnlyFileBasedBuffer) a ``close`` method.  Do not call ``close`` on an
    instance of such a class when it's used as a WSGI app_iter, however.  This is
    part of a fix which prevents a leakage of file descriptors; the other part of
    the fix was in WebOb
  - Allow trusted proxies to override ``wsgi.url_scheme`` via a request header,
    ``X_FORWARDED_PROTO``.  Allows proxies which serve mixed HTTP / HTTPS
    requests to control signal which are served as HTTPS.  See
  - Fix some cases where the creation of extremely large output buffers (greater
    than 2GB, suspected to be buffers added via ``wsgi.file_wrapper``) might
    cause an OverflowError on Python 2.  See
  - When the ``url_prefix`` adjustment starts with more than one slash, all
    slashes except one will be stripped from its beginning.  This differs from
    older behavior where more than one leading slash would be preserved in
  - If a client somehow manages to send an empty path, we no longer convert the
    empty path to a single slash in ``PATH_INFO``.  Instead, the path remains
    empty.  According to RFC 2616 section "5.1.2 Request-URI", the scenario of a
    client sending an empty path is actually not possible because the request URI
    portion cannot be empty.
  - If the ``url_prefix`` adjustment matches the request path exactly, we now
    compute ``SCRIPT_NAME`` and ``PATH_INFO`` properly.  Previously, if the
    ``url_prefix`` was ``/foo`` and the path received from a client was ``/foo``,
    we would set *both* ``SCRIPT_NAME`` and ``PATH_INFO`` to ``/foo``.  This was
    incorrect.  Now in such a case we set ``PATH_INFO`` to the empty string and
    we set ``SCRIPT_NAME`` to ``/foo``.  Note that the change we made has no
    effect on paths that do not match the ``url_prefix`` exactly (such as
    ``/foo/bar``); these continue to operate as they did.  See
  - Preserve header ordering of headers with the same name as per RFC 2616.  See
  - When waitress receives a ``Transfer-Encoding: chunked`` request, we no longer
    send the ``TRANSFER_ENCODING`` nor the ``HTTP_TRANSFER_ENCODING`` value to
    the application in the environment.  Instead, we pop this header.  Since we
    cope with chunked requests by buffering the data in the server, we also know
    when a chunked request has ended, and therefore we know the content length.
    We set the content-length header in the environment, such that applications
    effectively never know the original request was a T-E: chunked request; it
    will appear to them as if the request is a non-chunked request with an
    accurate content-length.
  - Cope with the fact that the ``Transfer-Encoding`` value is case-insensitive.
  - When the ``--unix-socket-perms`` option was used as an argument to
    ``waitress-serve``, a ``TypeError`` would be raised.  See
- Enable testsuite during build
* Wed Sep 11 2013
- update to 0.8.7:
  - The HTTP version of the response returned by waitress when it catches an
  exception will now match the HTTP request version.
* Tue Aug 13 2013
- update to 0.8.6:
  - Do alternate type of checking for UNIX socket support, instead of checking
  for platform == windows.
  - Functional tests now use multiprocessing module instead of subprocess module,
  speeding up test suite and making concurrent execution more reliable.
  - Runner now appends the current working directory to ``sys.path`` to support
  running WSGI applications from a directory (i.e., not installed in a
* Tue Jun 25 2013
- update to 0.8.5:
  - Fix runner multisegment imports in some Python 2 revisions (see
  - For compatibility, WSGIServer is now an alias of TcpWSGIServer. The
  signature of BaseWSGIServer is now compatible with WSGIServer pre-0.8.4.
  - Add a command-line runner called ``waitress-serve`` to allow Waitress
  to run WSGI applications without any addional machinery. This is
  essentially a thin wrapper around the ``waitress.serve()`` function.
  - Allow parallel testing (e.g., under ``detox`` or ``nosetests --processes``)
  using PID-dependent port / socket for functest servers.
  - Fix integer overflow errors on large buffers. Thanks to Marcin Kuzminski
  for the patch.  See:
  - Add support for listening on Unix domain sockets.
