1.1rc2

• Exceptions raised by gevent’s SSL sockets are more consistent with the standard library (e.g., gevent’s Python 3 SSL sockets raise socket.timeout instead of ssl.SSLError, a change introduced in Python 3.2).
• Python 2: gevent’s socket’s sendall method could completely ignore timeouts in some cases. The timeout now refers to the total time taken by sendall.
• gevent’s SSL socket’s sendall method should no longer raise SSL3_WRITE_PENDING in rare cases when sending large buffers. Reported in issue #317.
• gevent.signal now allows resetting (SIG_DFL) and ignoring (SIG_IGN) the SIGCHLD signal at the process level (although this may allow race conditions with libev child watchers). Reported in issue #696 by Adam Ning.
• gevent.spawn_raw() now accepts keyword arguments, as previously (incorrectly) documented. Reported in issue #680 by Ron Rothman.
• PyPy: PyPy 2.6.1 or later is now required (4.0.1 or later is recommended).
• The CFFI backend is now built and usable on CPython implementations (except on Windows) if cffi is installed before gevent is installed. To use the CFFI backend, set the environment variable GEVENT_CORE_CFFI_ONLY before starting Python. This can aid debugging in some cases and helps ensure parity across all combinations of supported platforms.
• The CFFI backend now calls the callback of a watcher whose args attribute is set to None, just like the Cython backend does. It also only allows args to be a tuple or None, again matching the Cython backend.
• PyPy/CFFI: Fix a potential crash when using stat watchers.
• PyPy/CFFI: Encode unicode paths for stat watchers using sys.getfilesystemencoding() like the Cython backend.
• The internal implementation modules gevent._fileobject2, gevent._fileobject3, and gevent._util were removed. These haven’t been used or tested since 1.1b1.
