Changelog

1.2.2

==================

• Testing on Python 3.5 now uses Python 3.5.3 due to SSL changes. See
  :issue:943.
• Linux CI has been updated from Ubuntu 12.04 to Ubuntu 14.04 since
  the former has reached EOL.
• Linux CI now tests on PyPy2 5.7.1, updated from PyPy2 5.6.0.
• Linux CI now tests on PyPy3 3.5-5.7.1-beta, updated from PyPy3
  3.3-5.5-alpha.
• Python 2 sockets are compatible with the SOCK_CLOEXEC flag found
  on Linux. They no longer pass the socket type or protocol to
  getaddrinfo when connect is called. Reported in :issue:944
  by Bernie Hackett.
• Replace optparse module with argparse. See :issue:947.
• Update to version 1.3.1 of tblib to fix :issue:954,
  reported by ml31415.
• Fix the name of the type parameter to
  :func:gevent.socket.getaddrinfo to be correct on Python 3. This
  would cause callers using keyword arguments to raise a :exc:TypeError.
  Reported in :issue:960 by js6626069. Likewise, correct the
  argument names for fromfd and socketpair on Python 2,
  although they cannot be called with keyword arguments under CPython.

.. note:: The gethost* functions take different argument names
under CPython and PyPy. gevent follows the CPython
convention, although these functions cannot be called with
keyword arguments on CPython.

• The previously-singleton exception objects FileObjectClosed and
  cancel_wait_ex were converted to classes. On Python 3, an
  exception object is stateful, including references to its context
  and possibly traceback, which could lead to objects remaining alive
  longer than intended.
• Make sure that python -m gevent.monkey <script> runs code in the
  global scope, not the scope of the main function. Fixed in
  :pr:975 by Shawn Bohrer.

1.2.1

==================

• CI services now test on 3.6.0.
• Windows: Provide socket.socketpair for all Python 3 versions.
  This was added to Python 3.5, but tests were only added in 3.6.
  (For versions older than 3.4 this is a gevent extension.) Previously
  this was not supported on any Python 3 version.
• Windows: List subprocess.STARTUPINFO in subprocess.__all__
  for 3.6 compatibility.
• The _DummyThread objects created by calling
  :func:threading.current_thread from inside a raw
  :class:greenlet.greenlet in a system with monkey-patched
  threading now clean up after themselves when the
  greenlet dies (:class:gevent.Greenlet-based _DummyThreads have
  always cleaned up). This requires the use of a :class:weakref.ref
  (and may not be timely on PyPy).
  Reported in :issue:918 by frozenoctobeer.
• Build OS X wheels with -D_DARWIN_FEATURE_CLOCK_GETTIME=0 for
  compatibility with OS X releases before 10.12 Sierra. Reported by
  Ned Batchelder in :issue:916.

1.2.0

==================

• The c-ares DNS resolver ignores bad flags to getnameinfo, like the
  system resolver does. Discovered when cleaning up the DNS resolver
  tests to produce more reliable results. See :issue:774.

1.2a2

===================

• Update libev to version 4.23.
• Allow the MAKE environment variable to specify the make command
  on non-Windows systems for ease of development on BSD systems where
  make is BSD make and gmake is GNU make (gevent requires GNU
  make). See :issue:888.
• Let :class:gevent.server.StreamServer accept an SSLContext on
  Python versions that support it. Added in :pr:904 by Arcadiy Ivanov.

1.2a1

====================

Incompatible Changes

• Support for Python 2.6 has been removed. See :pr:766.
• Remove module gevent.coros which was replaced by gevent.lock
  and has been deprecated since 1.0b2.
• The internal implementation modules gevent.corecext and
  gevent.corecffi have been moved. Please import from
  gevent.core instead; this has always been the only documented place to
  import from.

Libraries and Installation

• Update libev to version 4.22 (was 4.20).
• Update tblib to 1.3.0.
• Update Cython to 0.25 (was 0.23.5).
• Update c-ares to version 1.12.0 (was 1.10.0) (release notes <https://c-ares.haxx.se/changelog.html>_).
• For the benefit of downstream package maintainers, gevent is now
  tested with c-ares and libev linked dynamically and not embedded
  (i.e., using the system libraries). However, only the versions
  shipped with gevent are tested and known to work.
• The repository directory layout has been changed to make it easier
  to include third-party dependencies. Likewise, the setup.py script
  has been split to make it easier to build third-party dependencies.
• PyPy/CFFI: The corecffi native extension is now only built at
  installation time. Previously, if it wasn't available, a build was
  attempted at every import. This could lead to scattered "gevent"
  directories and undependable results.
• setuptools is now required at build time on all platforms.
  Previously it was only required for Windows and PyPy.
• POSIX: Don't hardcode /bin/sh into the configuration command
  line, instead relying on sh being on the PATH, as
  recommended by the standard <http://pubs.opengroup.org/onlinepubs/9699919799/utilities/sh.html>_.
  Fixed in :pr:809 by Fredrix Fornwall.

Security

• :mod:gevent.pywsgi now checks that the values passed to
  start_response do not contain a carriage return or newline in
  order to prevent HTTP response splitting (header injection), raising
  a :exc:ValueError if they do. See :issue:775.
• Incoming headers containing an underscore are no longer placed in
  the WSGI environ. See :issue:819.
• Errors logged by :class:~gevent.pywsgi.WSGIHandler no
  longer print the entire WSGI environment by default. This avoids
  possible information disclosure vulnerabilities. Applications can
  also opt-in to a higher security level for the WSGI environment if they
  choose and their frameworks support it. Originally reported
  in :pr:779 by sean-peters-au and changed in :pr:781.

Platforms

• As mentioned above, Python 2.6 is no longer supported.
• Python 3.6 is now tested on POSIX platforms. This includes a few
  notable changes:

• SSLContext.wrap_socket accepts the session parameter, though
  this parameter isn't useful prior to 3.6.
• SSLSocket.recv(0) or read(0) returns an empty byte string. This is
  a fix for Python bug 23804 <http://bugs.python.org/issue23804>_
  which has also been merged into Python 2.7 and Python 3.5.

• PyPy3 5.5.0 alpha (supporting Python 3.3.5) is now tested and passes the
  test suite. Thanks to btegs for :issue:866, and Fabio Utzig for :pr:826.
  Note that PyPy3 is not optimized for performance either by the PyPy
  developers or under gevent, so it may be significantly slower than PyPy2.

Stdlib Compatibility

• The modules :mod:gevent.os, :mod:gevent.signal and
  :mod:gevent.select export all the attributes from their
  corresponding standard library counterpart.
• Python 2: reload(site) no longer fails with a TypeError if
  gevent has been imported. Reported in :issue:805 by Jake Hilton.
• Python 2: sendall on a non-blocking socket could spuriously fail
  with a timeout.

select/poll

• If :func:gevent.select.select is given a negative timeout
  argument, raise an exception like the standard library does.
• If :func:gevent.select.select is given closed or invalid
  file descriptors in any of its lists, raise the appropriate
  EBADF exception like the standard library does. Previously,
  libev would tend to return the descriptor as ready. In the worst
  case, this adds an extra system call, but may also reduce latency if
  descriptors are ready at the time of entry.
• :class:selectors.SelectSelector is properly monkey-patched
  regardless of the order of imports. Reported in :issue:835 by
  Przemysław Węgrzyn.
• :meth:gevent.select.poll.unregister raises an exception if fd is not
  registered, like the standard library.
• :meth:gevent.select.poll.poll returns an event with
  POLLNVAL for registered fds that are invalid. Previously it
  would tend to report both read and write events.

File objects

• FileObjectPosix exposes the read1 method when in read mode,
  and generally only exposes methods appropriate to the mode it is in.
• FileObjectPosix supports a bufsize of 0 in binary write modes.
  Reported in :issue:840 by Mike Lang.
• Python 3: :meth:gevent.socket.connect_ex was letting
  BlockingIOError (and possibly others) get raised instead of
  returning the errno due to the refactoring of the exception
  hierarchy in Python 3.3. Now the errno is returned. Reported in
  :issue:841 by Dana Powers.

Other Changes

• :class:~.Group and :class:~.Pool now return whether
  :meth:~.Group.join returned with an empty group. Suggested by Filippo Sironi in
  :pr:503.
• Unhandled exception reports that kill a greenlet now include a
  timestamp. See :issue:137.
• :class:~.PriorityQueue now ensures that an initial items list is a
  valid heap. Fixed in :pr:793 by X.C.Dong.
• :class:gevent.hub.signal (aka :func:gevent.signal) now verifies
  that its handler argument is callable, raising a :exc:TypeError
  if it isn't. Reported in :issue:818 by Peter Renström.
• If sys.stderr has been monkey-patched (not recommended),
  exceptions that the hub reports aren't lost and can still be caught.
  Reported in :issue:825 by Jelle Smet.
• The :func:gevent.os.waitpid function is cooperative in more
  circumstances. Reported in :issue:878 by Heungsub Lee.
• The various FileObject implementations are more consistent with
  each other. Note: Writing to the io property of a FileObject should be
  considered deprecated.
• Timeout exceptions (and other asynchronous exceptions) could cause
  the BackdoorServer to fail to properly manage the
  stdout/stderr/stdin values. Reported with a patch in :pr:874 by
  stefanmh.
• The BackDoorServer now tracks spawned greenlets (connections) and
  kills them in its stop method.

Servers

- Default to AF_INET6 when binding to all addresses (e.g.,
 ""). This supports both IPv4 and IPv6 connections (except on
 Windows). Original change in :pr:`495` by Felix Kaiser.
- pywsgi/performance: Chunks of data the application returns are no longer copied
 before being sent to the socket when the transfer-encoding is
 chunked, potentially reducing overhead for large responses.

Threads

- Add :class:`gevent.threadpool.ThreadPoolExecutor` (a
 :class:`concurrent.futures.ThreadPoolExecutor` variant that always
 uses native threads even when the system has been monkey-patched)
 on platforms that have ``concurrent.futures``
 available (Python 3 and Python 2 with the ``futures`` backport
 installed). This is helpful for, e.g., grpc. Reported in
 :issue:`786` by Markus Padourek.
- Native threads created before monkey-patching threading can now be
 joined. Previously on Python < 3.4, doing so would raise a
 ``LoopExit`` error. Reported in :issue:`747` by Sergey Vasilyev.

SSL

- On Python 2.7.9 and above (more generally, when the SSL backport is
 present in Python 2), :func:`gevent.ssl.get_server_certificate`
 would raise a :exc:`ValueError` if the system wasn't monkey-patched.
 Reported in :issue:`801` by Gleb Dubovik.
- On Python 2.7.9 and Python 3, closing an SSL socket in one greenlet
 while it's being read from or written to in a different greenlet is
 less likely to raise a :exc:`TypeError` instead of a
 :exc:`ValueError`. Reported in :issue:`800` by Kevin Chen.

subprocess module

• Setting SIGCHLD to SIG_IGN or SIG_DFL after :mod:gevent.subprocess
  had been used previously could not be reversed, causing
  Popen.wait and other calls to hang. Now, if SIGCHLD has been
  ignored, the next time :mod:gevent.subprocess is used this will be
  detected and corrected automatically. (This potentially leads to
  issues with :func:os.popen on Python 2, but the signal can always
  be reset again. Mixing the low-level process handling calls,
  low-level signal management and high-level use of
  :mod:gevent.subprocess is tricky.) Reported in :issue:857 by
  Chris Utz.
• Popen.kill and send_signal no longer attempt to send signals
  to processes that are known to be exited.

Several backwards compatible updates to the subprocess module have
been backported from Python 3 to Python 2, making
:mod:gevent.subprocess smaller, easier to maintain and in some cases
safer.

• Popen objects can be used as context managers even on Python 2. The
  high-level API functions (call, etc) use this for added safety.
• The :mod:gevent.subprocess module now provides the
  :func:gevent.subprocess.run function in a cooperative way even
  when the system is not monkey patched, on all supported versions of
  Python. (It was added officially in Python 3.5.)
• Popen objects save their args attribute even on Python 2.
• :exc:gevent.subprocess.TimeoutExpired is defined even on Python 2,
  where it is a subclass of the :exc:gevent.timeout.Timeout
  exception; all instances where a Timeout exception would
  previously be thrown under Python 2 will now throw a
  TimeoutExpired exception.
• :func:gevent.subprocess.call (and check_call) accepts the
  timeout keyword argument on Python 2. This is standard on Python
  3, but a gevent extension on Python 2.
• :func:gevent.subprocess.check_output accepts the timeout and
  input arguments on Python 2. This is standard on Python 3, but a
  gevent extension on Python 2.
