Eventlet 0.20.0 released
Eventlet is a concurrent networking library for Python that allows you to
change how you run your code, not how you write it.
https://pypi.python.org/pypi/eventlet/0.20.0
Important backward incompatible changes:
- removed select.poll(). We never had green poll implementation. If you really
need blocking poll, use patcher.original('select').
- DNS resolving is always green with dnspython bundled in. This is just a nice
free improvement. Be alert only if you intentionally wanted blocking resolving.
Other goodies:
* greenio: only trampoline when we block
* convenience: listen() sets SO_REUSEPORT when available; Thanks to Zhengwei Gao
* ssl: Fix "TypeError: read() argument 2 must be read-write bytes-like object,
not None"
* greenio: _recv_loop behaviour with recv_into on closed sock
* ipv6: getaddrinfo would fail with scope index
* green.zmq: Support {send,recv}_{string,json,pyobj} wrappers
* greendns: Return answers from /etc/hosts despite nameserver errors
* patcher: fixed green existing locks fail (Python3)
* Add DAGPool, a dependency-driven greenthread pool
* wsgi: Unix socket address representation; Thanks to Samuel Merritt
* tpool: isolate internal socket from default timeout; Thanks to Alex Villacís
Lasso
* wsgi: only skip Content-Type and Content-Length headers (GH-327)
* wsgi: 400 on blank Content-Length headers (GH-334)
* greenio: makefile related pypy socket ref counting
* ssl: Fix recv_into blocking when reading chunks of data
* websocket: support Gunicorn environ['gunicorn.socket']

Eventlet 0.18.3 released
Eventlet is a concurrent networking library for Python that allows you to change how you run your code, not how you write it. https://pypi.python.org/pypi/eventlet/0.18.3 The most scandal Eventlet release so far: https://pypi.python.org/pypi/eventlet/0.18.3 *Important note*: do not use versions 0.18.0 and 0.18.1, they contain known bug in wsgi on Python3. 0.18 line features Python3 compatible green.OpenSSL. Now important backward incompatible changes: - socket.send() will return fast, it no longer attempts to retry like sendall() which makes it consistent with Python standard library and removes a source of very subtle errors. - monkey patching removes things from `select` module, that we could not make green. This includes `select.poll()`, epoll, kqueue, etc. See full list here http://eventlet.net/doc/changelog.html the motivation here is that we want to prevent you from accidentally blocking whole process, while thinking it should all work together. Other goodies: * greenio: Fixed a bug that could cause send() to start an endless loop on ENOTCONN; Thanks to Seyeong Kim * wsgi: Fixed UNIX socket address being trimmed in "wsgi starting" log; Thanks to Ihar Hrachyshka * subprocess: Fixed missing subprocess.mswindows attribute on Python 3.5; Thanks to Josh VanderLinden * ssl/monkey patching: Fixed a bug that would cause merely importing eventlet to monkey patch the ssl module; Thanks to David Szotten * wsgi: Made the error raised in case of chunk read failures more precise (this should be backwards compatible as the new exception class, wsgi.ChunkReadError, is a subclass of ValueError which was being used there before); Thanks to Samuel Merritt * greenio: Fixed socket.recv() sometimes returning str instead of bytes on Python 3; Thanks to Janusz Harkot * websocket: Fixed TypeError on empty websocket message (Python 3); Thanks to Fukuchi Daisuke * greenio: Fixed handling blocking IO errors in various GreenSocket methods; Thanks to Victor Stinner * greenio: Fixed GreenPipe ignoring the bufsize parameter on Python 2; Thanks to Phus Lu * greenio: Made read() support buflen=-1 and added readall() (Python 3); Thanks to David Szotten * wsgi: Improved request body discarding * subprocess: Fixed universal_newlines support * wsgi: Output of 0-byte chunks is now suppressed; Thanks to Samuel Merritt Improved the documentation; Thanks to Ramakrishnan G, ashutosh-mishra and Azhar Hussain * greenio: Changed GreenFileIO.write() (Python 3) to always write all data to match the behavior on Python 2; Thanks to Victor Stinner documentation: Added support for building plain text documentation; thanks to Levente Polyak * backdoor: Added Unix and IPv6 socket support; Thanks to Eric Urban Our website: http://eventlet.net/ Direct package download links: https://pypi.python.org/packages/3.4/e/eventlet/eventlet-0.18.3-py2.py3-none-any.whl https://pypi.python.org/packages/source/e/eventlet/eventlet-0.18.3.tar.gz -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/

Eventlet 0.16.1
Eventlet is a concurrent networking library for Python that allows you to change how you run your code, not how you write it. http://pypi.python.org/pypi/eventlet/0.16.1 This release features Python 2.7.9 SSL compatibility and improved Python3 support (bleeding edge, not finished officially). Thanks to all contributors! Also, we removed lots of deprecated unsupported code, including Twisted hub. This will allow us to focus on what's important and get there sooner. Next targets: Python3 and IPv6. Important note if you already installed v0.16.0: please, take a minute and update your build to 0.16.1. Module eventlet.util was removed from source tree and tarball but still made it into wheel package by my mistake. You may have code that depends (but shouldn't) on this module and will work in some cases.

Eventlet 0.13 is going to have minor incompatible change in subprocess API
Hello. I'm trying to reach out for as many Eventlet users as possible. This message contains specific actions to be taken by project owners to ensure compatibility with future versions of eventlet. 1. We're going to have a minor backward incompatible change. It will *only* affect you if you use Eventlet specific `check_interval` positional argument, e.g. subprocess.Popen(...).wait(0.1). Which is very unlikely, but I have to make sure. Checking will take less than minute best case. 2. Please run the following search against your code base: grep -lr -E 'import.+subprocess' . |xargs grep -nE '\.wait\([^)]' |fgrep -v 'check_interval=' 3. If you have any results on step 3, please check that either you imported subprocess from eventlet.green or used monkey_patch and matched lines correspond to eventlet.green.subprocess.Popen objects 4. If you have any results on step 4, that is, you pass check_interval as first positional argument to .wait() method of Popen object, please change it to keyword argument `check_interval=...` 5. Please, spread this message to your coworkers, friends or other people who uses Eventlet in their projects. Thank you very much. If you are curious what's going on, here's the full story: Python 3.3 introduced `timeout` kwarg to lots of methods of subprocess module. The RHEL guys backported it to their Python 2.6 package. At some point, the code they used started to use subprocess from Eventlet which does not have the `timeout` kwarg. https://bitbucket.org/eventlet/eventlet/issue/89 https://bitbucket.org/eventlet/eventlet/pull-request/30 Now in Eventlet, I am going to introduce the `timeout` argument and to make it forward compatible with Python3, it's going to get first place, like in stdlib.
