+=====
+
+* Moved get_hub, use_hub, get_default_hub to eventlet.hubs
+* Renamed libevent hub to pyevent.
+* Renamed coros.event to coros.Event
+* Removed previously-deprecated features tcp_server, GreenSSL, erpc, and trap_errors.

+=====
+
+* Bugfix for wsgi.py where it was improperly expecting the environ variable to be a constant when passed to the application.
+* Tpool.py now passes its tests on Windows.
+* Fixed minor performance issue in wsgi.
+
+0.9.1
+=====
+
+* PyOpenSSL is no longer required for Python 2.6: use the eventlet.green.ssl module. 2.5 and 2.4 still require PyOpenSSL.
+* Cleaned up the eventlet.green packages and their associated tests, this should result in fewer version-dependent bugs with these modules.
+* PyOpenSSL is now fully wrapped in eventlet.green.OpenSSL; using it is therefore more consistent with using other green modules.
+* Documentation on using SSL added.
+* New green modules: ayncore, asynchat, SimpleHTTPServer, CGIHTTPServer, ftplib.
+* Fuller thread/threading compatibility: patching threadlocal with corolocal so coroutines behave even more like threads.
+* Improved Windows compatibility for tpool.py
+* With-statement compatibility for pools.Pool objects.
+* Refactored copyrights in the files, added LICENSE and AUTHORS files.
+* Added support for logging x-forwarded-for header in wsgi.
+* api.tcp_server is now deprecated, will be removed in a future release.
+* Added instructions on how to generate coverage reports to the documentation.
+* Renamed GreenFile to Green_fileobject, to better reflect its purpose.

+Using SSL With Eventlet
+========================
+
+Eventlet makes it easy to use non-blocking SSL sockets. If you're using Python 2.6 or later, you're all set, eventlet wraps the built-in ssl module. If on Python 2.5 or 2.4, you have to install pyOpenSSL_ to use eventlet.
+
+In either case, the the ``green`` modules handle SSL sockets transparently, just like their standard counterparts. As an example, :mod:`eventlet.green.urllib2` can be used to fetch https urls in as non-blocking a fashion as you please::
+
+ from eventlet.green import urllib2
+ from eventlet import coros
+ bodies = [coros.execute(urllib2.urlopen, url)
+ for url in ("https://secondlife.com","https://google.com")]
+ for b in bodies:
+ print b.wait().read()
+
+
+With Python 2.6
+----------------
+
+To use ssl sockets directly in Python 2.6, use :mod:`eventlet.green.ssl`, which is a non-blocking wrapper around the standard Python :mod:`ssl` module, and which has the same interface. See the standard documentation for instructions on use.
+
+With Python 2.5 or Earlier
+---------------------------
+
+Prior to Python 2.6, there is no :mod:`ssl`, so SSL support is much weaker. Eventlet relies on pyOpenSSL to implement its SSL support on these older versions, so be sure to install pyOpenSSL, or you'll get an ImportError whenever your system tries to make an SSL connection.
+
+Once pyOpenSSL is installed, you can then use the ``eventlet.green`` modules, like :mod:`eventlet.green.httplib` to fetch https urls. You can also use :func:`eventlet.green.socket.ssl`, which is a nonblocking wrapper for :func:`socket.ssl`.
+
+PyOpenSSL
+----------
+
+:mod:`eventlet.green.OpenSSL` has exactly the same interface as pyOpenSSL_ `(docs) `_, and works in all versions of Python. This module is much more powerful than :func:`socket.ssl`, and may have some advantages over :mod:`ssl`, depending on your needs.
+
+Here's an example of a server::
+
+ from eventlet.green import socket
+ from eventlet.green.OpenSSL import SSL
+
+ # insecure context, only for example purposes
+ context = SSL.Context(SSL.SSLv23_METHOD)
+ context.set_verify(SSL.VERIFY_NONE, lambda *x: True))
+
+ # create underlying green socket and wrap it in ssl
+ sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
+ connection = SSL.Connection(context, sock)
+
+ # configure as server
+ connection.set_accept_state()
+ connection.bind(('127.0.0.1', 80443))
+ connection.listen(50)
+
+ # accept one client connection then close up shop
+ client_conn, addr = connection.accept()
+ print client_conn.read(100)
+ client_conn.shutdown()
+ client_conn.close()
+ connection.close()

Eventlet provides for the ability to test itself with the standard Python networking tests. This verifies that the libraries it wraps work at least as well as the standard ones do. The directory tests/stdlib contains a bunch of stubs that import the standard lib tests from your system and run them. If you do not have any tests in your python distribution, they'll simply fail to import.
-Run the standard library tests with nose; simply do:
+There's a convenience module called all.py designed to handle the impedance mismatch between Nose and the standard tests:
.. code-block:: sh
- $ cd tests/
- $ nosetests stdlib
+ $ nosetests tests/stdlib/all.py
-That should get you started. At this time this generates a bunch of spurious failures, due to `Nose issue 162 `_, which incorrectly identifies helper methods as test cases. Therefore, ignore any failure for the reason ``TypeError: foo() takes exactly N arguments (2 given)``, and sit tight until a version of Nose is released that fixes the issue.
+That will run all the tests, though the output will be a little weird because it will look like Nose is running about 20 tests, each of which consists of a bunch of sub-tests. Not all test modules are present in all versions of Python, so there will be an occasional printout of "Not importing %s, it doesn't exist in this installation/version of Python".

+Coverage
+--------
+Coverage.py is an awesome tool for evaluating how much code was exercised by unit tests. Nose supports it if both are installed, so it's easy to generate coverage reports for eventlet. Here's how:
+
+.. code-block:: sh
+
+ nosetests --with-coverage
+
+After running the tests to completion, this will emit a huge wodge of module names and line numbers. For some reason, the ``--cover-inclusive`` option breaks everything rather than serving its purpose of limiting the coverage to the local files, so don't use that.
+
+The annotate option is quite useful because it generates annotated source files that are much easier to read than line-number soup. Here's a command that runs the annotation, dumping the annotated files into a directory called "annotated":

+ coverage annotate -d annotated --omit tempmod

-"""HTTP/1.1 client library
-
-
-
-
-HTTPConnection goes through a number of "states", which define when a client
-may legally make another request or fetch the response for a particular
-request. This diagram details these state transitions:
-
- (null)
- |
- | HTTPConnection()
- v
- Idle
- |
- | putrequest()
- v
- Request-started
- |
- | ( putheader() )* endheaders()
- v
- Request-sent
- |
- | response = getresponse()
- v
- Unread-response [Response-headers-read]
- |\____________________
- | |
- | response.read() | putrequest()
- v v
- Idle Req-started-unread-response
- ______/|
- / |
- response.read() | | ( putheader() )* endheaders()
- v v
- Request-started Req-sent-unread-response
- |
- | response.read()
- v
- Request-sent
-
-This diagram presents the following rules:
- -- a second request may not be started until {response-headers-read}
- -- a response [object] cannot be retrieved until {request-sent}
- -- there is no differentiation between an unread response body and a
- partially read response body
-
-Note: this enforcement is applied by the HTTPConnection class. The
- HTTPResponse class does not enforce this state machine, which
- implies sophisticated clients may accelerate the request/response
- pipeline. Caution should be taken, though: accelerating the states
- beyond the above pattern may imply knowledge of the server's
- connection-close behavior for certain requests. For example, it
- is impossible to tell whether the server will close the connection
- UNTIL the response headers have been read; this means that further
- requests cannot be placed into the pipeline until it is known that
- the server will NOT be closing the connection.

+""" Convenience module for running standard library tests with nose. The standard tests are not especially homogeneous, but they mostly expose a test_main method that does the work of selecting which tests to run based on what is supported by the platform. On its own, Nose would run all possible tests and many would fail; therefore we collect all of the test_main methods here in one module and Nose can run it. Hopefully in the future the standard tests get rewritten to be more nosey.
+
+Many of these tests make connections to external servers, and all.py tries to skip these tests rather than failing them, so you can get some work done on a plane.
