Changelog

1.4.0 (2019-01-04)

  • Build with Cython 0.29 in ‘3str’ mode.

  • Test with PyPy 6.0 on Windows.

  • Add support for application-wide callbacks when Greenlet objects are started. See pull request #1289, provided by Yury Selivanov.

  • Fix consuming a single ready object using next(gevent.iwait(objs)). Previously such a construction would hang because iter was not called. See pull request #1288, provided by Josh Snyder. This is not recommended, though, as unwaited objects will have dangling links (but see next item).

  • Make gevent.iwait return an iterator that can now also be used as a context manager. If you’ll only be consuming part of the iterator, use it in a with block to avoid leaking resources. See pull request #1290, provided by Josh Snyder.

  • Fix semaphores to immediately notify links if they are ready and rawlink() is called. This behaves like Event and AsyncEvent. Note that the order in which semaphore links are called is not specified. See issue #1287, reported by Dan Milon.

  • Improve safety of handling exceptions during interpreter shutdown. See issue #1295 reported by BobDenar1212.

  • Remove the deprecated ability to specify GEVENT_RESOLVER and other importable settings as a path/to/a/package.module.item. This had race conditions and didn’t work with complicated resolver implementations. Place the required package or module on sys.path first.

  • Reduce the chances that using the blocking monitor functionality could result in apparently random SystemError: Objects/tupleobject.c: bad argument to internal function. Reported in issue #1302 by Ulrich Petri.

  • Refactored the gevent test runner and test suite to make them more reusable. In particular, the tests are now run with python -m gevent.tests. See issue #1293.

  • Make a monkey-patched socket.getaddrinfo return socket module enums instead of plain integers for the socket type and address family on Python 3. See issue #1310 reported by TheYOSH.

    Note

    This requires Python 3.4.3 or above due to an undocumented change in that version.

  • Make gevent’s pywsgi server set the non-standard environment value wsgi.input_terminated to True. See issue #1308.

  • Make gevent.util.assert_switches produce more informative messages when the assertion fails.

  • Python 2: If a gevent.socket was closed asynchronously (in a different greenlet or a hub callback), AttributeError could result if the socket was already in use. Now the correct socket.error should be raised.

  • Fix gevent.threadpool.ThreadPool.join() raising a UserWarning when using the libuv backend. Reported in issue #1321 by ZeroNet.

  • Fix FileObjectPosix.seek raising OSError when it should have been IOError on Python 2. Reported by, and PR by, Ricardo Kirkner. See issue #1323.

  • Upgrade libuv from 1.23.2 to 1.24.0.
