- Python 3: A monkey-patched :class:
threading.RLocknow properly blocks (or deadlocks) inacquireif the default value for timeout of -1 is used (which differs from gevent's default of None). Theacquiremethod also raises the same :exc:ValueErrorexceptions that the standard library does for invalid parameters. Reported in [#750] by Joy Zheng. - Fix a race condition in :class:
~gevent.event.Eventthat made it returnFalsewhen the event was set and cleared by the same greenlet before allowing a switch to already waiting greenlets. (Found by the 3.4 and 3.5 standard library test suites; the same as Pythonbug 13502_. Note that the Python 2 standard library still has this race condition.) - :class:
~gevent.event.Eventand :class:~.AsyncResultnow wake waiting greenlets in the same (unspecified) order. Previously,AsyncResulttended to use a FIFO order, but this was never guaranteed. Both classes also use less per-instance memory. - Using a :class:
~logging.Loggeras a :mod:pywsgierror or request log stream no longer produces extra newlines. Reported in [#756] by ael-code. - Windows: Installing from an sdist (.tar.gz) on PyPI no longer requires having Cython installed first. (Note that the binary installation formats (wheels, exes, msis) are preferred on Windows.) Reported in [#757] by Ned Batchelder.
- Issue a warning when :func:
~gevent.monkey.patch_allis called withosset to False (not the default) butsignalis still True (the default). This combination of parameters will cause signal handlers forSIGCHLDto not get called. In the future this might raise an error. Reported by Josh Zuech. - Issue a warning when :func:
~gevent.monkey.patch_allis called more than once with different arguments. That causes the cumulative set of all True arguments to be patched, which may cause unexpected results. - Fix returning the original values of certain
threadingattributes from :func:gevent.monkey.get_original.
