unreleased
----------
Deprecations
~~~~~~~~~~~~
- The ``send_bytes`` adjustment now defaults to ``1`` and is deprecated
pending removal in a future release.
and https://github.com/Pylons/waitress/pull/246
Features
~~~~~~~~
- Stop early and close the ``app_iter`` when attempting to write to a closed
socket due to a client disconnect. This should notify a long-lived streaming
response when a client hangs up.
See https://github.com/Pylons/waitress/pull/238
and https://github.com/Pylons/waitress/pull/240
and https://github.com/Pylons/waitress/pull/241
- Adjust the flush to output ``SO_SNDBUF`` bytes instead of whatever was
set in the ``send_bytes`` adjustment. ``send_bytes`` now only controls how
much waitress will buffer internally before flushing to the kernel, whereas
previously it used to also throttle how much data was sent to the kernel.
This change enables a streaming ``app_iter`` containing small chunks to
still be flushed efficiently.
See https://github.com/Pylons/waitress/pull/246
Bugfixes
~~~~~~~~
- When a client closes a socket unexpectedly there was potential for memory
leaks in which data was written to the buffers after they were closed,
causing them to reopen.
See https://github.com/Pylons/waitress/pull/239
- Fix the queue depth warnings to only show when all threads are busy.
See https://github.com/Pylons/waitress/pull/243
- Trigger the ``app_iter`` to close as part of shutdown. This will only be
noticeable for users of the internal server api. In more typical operations
the server will die before benefiting from these changes.
See https://github.com/Pylons/waitress/pull/245
1.2.1 (2019-01-25)
------------------
Bugfixes
~~~~~~~~
- When given an IPv6 address in ``X-Forwarded-For`` or ``Forwarded for=``
waitress was placing the IP address in ``REMOTE_ADDR`` with brackets:
``[2001:db8::0]``, this does not match the requirements in the CGI spec which
``REMOTE_ADDR`` was lifted from. Waitress will now place the bare IPv6
address in ``REMOTE_ADDR``: ``2001:db8::0``. See
https://github.com/Pylons/waitress/pull/232 and
https://github.com/Pylons/waitress/issues/230
1.2.0 (2019-01-15)
------------------
No changes since the last beta release. Enjoy Waitress!
1.2.0b3 (2019-01-07)
--------------------
Bugfixes
~~~~~~~~
- Modified ``clear_untrusted_proxy_headers`` to be usable without a
``trusted_proxy``.
https://github.com/Pylons/waitress/pull/228
- Modified ``trusted_proxy_count`` to error when used without a
``trusted_proxy``.
https://github.com/Pylons/waitress/pull/228
1.2.0b2 (2019-02-02)
--------------------
Bugfixes
~~~~~~~~
- Fixed logic to no longer warn on writes where the output is required to have
a body but there may not be any data to be written. Solves issue posted on
the Pylons Project mailing list with 1.2.0b1.
1.2.0b1 (2018-12-31)
--------------------
Happy New Year!
Features
~~~~~~~~
- Setting the ``trusted_proxy`` setting to ``'*'`` (wildcard) will allow all
upstreams to be considered trusted proxies, thereby allowing services behind
Cloudflare/ELBs to function correctly whereby there may not be a singular IP
address that requests are received from.
Using this setting is potentially dangerous if your server is also available
from anywhere on the internet, and further protections should be used to lock
down access to Waitress. See https://github.com/Pylons/waitress/pull/224
- Waitress has increased its support of the X-Forwarded-* headers and includes
Forwarded (RFC7239) support. This may be used to allow proxy servers to
influence the WSGI environment. See
https://github.com/Pylons/waitress/pull/209
This also provides a new security feature when using Waitress behind a proxy
in that it is possible to remove untrusted proxy headers thereby making sure
that downstream WSGI applications don't accidentally use those proxy headers
to make security decisions.
The documentation has more information, see the following new arguments:
- trusted_proxy_count
- trusted_proxy_headers
- clear_untrusted_proxy_headers
- log_untrusted_proxy_headers (useful for debugging)
Be aware that the defaults for these are currently backwards compatible with
older versions of Waitress, this will change in a future release of waitress.
If you expect to need this behaviour please explicitly set these variables in
your configuration, or pin this version of waitress.
Documentation:
https://docs.pylonsproject.org/projects/waitress/en/latest/reverse-proxy.html
- Waitress can now accept a list of sockets that are already pre-bound rather
than creating its own to allow for socket activation. Support for init
systems/other systems that create said activated sockets is not included. See
https://github.com/Pylons/waitress/pull/215
- Server header can be omitted by specifying ``ident=None`` or ``ident=''``.
See https://github.com/Pylons/waitress/pull/187
Bugfixes
~~~~~~~~
- Waitress will no longer send Transfer-Encoding or Content-Length for 1xx,
204, or 304 responses, and will completely ignore any message body sent by
the WSGI application, making sure to follow the HTTP standard. See
https://github.com/Pylons/waitress/pull/166,
https://github.com/Pylons/waitress/issues/165,
https://github.com/Pylons/waitress/issues/152, and
https://github.com/Pylons/waitress/pull/202
Compatibility
~~~~~~~~~~~~~
- Waitress has now "vendored" asyncore into itself as ``waitress.wasyncore``.
This is to cope with the eventuality that asyncore will be removed from
the Python standard library in 3.8 or so.
Documentation
~~~~~~~~~~~~~
- Bring in documentation of paste.translogger from Pyramid. Reorganize and
clean up documentation. See
https://github.com/Pylons/waitress/pull/205
https://github.com/Pylons/waitress/pull/70
https://github.com/Pylons/waitress/pull/206
