python-gevent/python-gevent.changes
Matej Cepl 2827e68802 - Upgrade to 1.5a3: 
- The file objects (FileObjectPosix, FileObjectThread) now
    consistently text and binary modes. If neither 'b' nor 't' is
    given in the mode, they will read and write native strings.
    If 't' is given, they will always work with unicode strings,
    and 'b' will always work with byte strings. (FileObjectPosix
    already worked this way.) See :issue:`1441`.
  - The file objects accept encoding, errors and newline
    arguments. On Python 2, these are only used if 't' is in the
    mode.
  - The default mode for FileObjectPosix changed from rb to
    simply r, for consistency with the other file objects and the
    standard open and io.open functions.
  - Fix FileObjectPosix improperly being used from multiple
    greenlets. Previously this was hidden by forcing buffering,
    which raised RuntimeError.
  - Fix using monkey-patched threading.Lock and threading.RLock
    objects as spin locks by making them call sleep(0) if they
    failed to acquire the lock in a non-blocking call. This lets
    other callbacks run to release the lock, simulating
    preemptive threading. Using spin locks is not recommended,
    but may have been done in code written for threads,
    especially on Python 3. See :issue:`1464`.
  - Fix Semaphore (and monkey-patched threading locks) to be
    fair. This eliminates the rare potential for starvation of
    greenlets. As part of this change, the low-level method
    rawlink of Semaphore, Event, and AsyncResult now always
    remove the link object when calling it, so unlink can
    sometimes be optimized out. See :issue:`1487`.
  - Make gevent.pywsgi support Connection: keep-alive in

Thu Jan 2 14:09:44 CET 2020 - Matej Cepl <mcepl@suse.com>
- Upgrade to 1.5a3:

given in the mode, they will read and write native strings.
If 't' is given, they will always work with unicode strings,

objects as spin locks by making them call sleep(0) if they
failed to acquire the lock in a non-blocking call. This lets
other callbacks run to release the lock, simulating
preemptive threading. Using spin locks is not recommended,
but may have been done in code written for threads,
especially on Python 3. See :issue:`1464`.
- Fix Semaphore (and monkey-patched threading locks) to be

greenlets. As part of this change, the low-level method
rawlink of Semaphore, Event, and AsyncResult now always
remove the link object when calling it, so unlink can
sometimes be optimized out. See :issue:`1487`.
- Make gevent.pywsgi support Connection: keep-alive in
HTTP/1.0. Based on :pr:`1331` by tanchuhan.
- Fix a potential crash using gevent.idle() when using libuv.
See :issue:`1489`.
- Fix some potential crashes using libuv async watchers.
- Make ThreadPool consistently raise InvalidThreadUseError when
spawn is called from a thread different than the thread that
created the threadpool. This has never been allowed, but was
inconsistently enforced. On gevent 1.3 and before, this would
always raise "greenlet error: invalid thread switch," or
LoopExit. On gevent 1.4, it could raise LoopExit, depending
on the number of tasks, but still, calling it from
a different thread was likely to corrupt libev or libuv
internals.
- Remove some undocumented, deprecated functions from the
threadpool module.
- libuv: Fix a perceived slowness spawning many greenlets at
the same time without yielding to the event loop while having
no active IO watchers or timers. If the time spent launching
greenlets exceeded the switch interval and there were no
other active watchers, then the default IO poll time of about
.3s would elapse between spawning batches. This could
theoretically apply for any non-switching callbacks. This can
be produced in synthetic benchmarks and other special
circumstances, but real applications are unlikely to be
affected. See :issue:`1493`.
- Fix using the threadpool inside a script or module run with
python -m gevent.monkey. Previously it would use greenlets
instead of native threads. See :issue:`1484`.
- Fix potential crashes in the FFI backends if a watcher was
closed and stopped in the middle of a callback from the event
loop and then raised an exception. This could happen if the
hub's handle_error function was poorly customized, for
example. See :issue:`1482`
- Make gevent.killall stop greenlets from running that hadn't
been run yet. This make it consistent with Greenlet.kill().
See :issue:`1473` reported by kochelmonster.
- Make gevent.spawn_raw set the loop attribute on returned
greenlets. This lets them work with more gevent APIs, notably
gevent.killall(). They already had dictionaries, but this may
make them slightly larger, depending on platform (on CPython
2.7 through 3.6 there is no apparent difference for one
attribute but on CPython 3.7 and 3.8 dictionaries are
initially empty and only allocate space once an attribute is
added; they're still smaller than on earlier versions
though).
- Add support for CPython 3.8.0. (Windows wheels are not yet
available.)
- Add an --module option to gevent.monkey allowing to run
a Python module rather than a script. See :pr:`1440`.
- Improve the way joining the main thread works on Python 3.
- Implement SSLSocket.verify_client_post_handshake() when
available.
- Fix tests when TLS1.3 is supported.
- Disable Nagle's algorithm in the backdoor server. This can
improve interactive response time.
- Test on Python 3.7.4. There are important SSL test fixes.
- Python version updates: gevent is now tested with CPython
2.7.16, 3.5.6, 3.6.8, and 3.7.2. It is also tested with PyPy2
7.1 and PyPy 3.6 7.1 (PyPy 7.0 and 7.1 were not capable of
running SSL tests on Travis CI).
- Support for Python 3.4 has been removed, as that version is
no longer supported uptstream.
- gevent binary wheels are now manylinux2010 and include libuv
support. pip 19 is needed to install them. See :issue:`1346`.
- gevent is now compiled with Cython 0.29.6 and cffi 1.12.2.
- gevent sources include a pyproject.toml file, specifying the
build requirements and enabling build isolation. pip 18 or
above is needed to take advantage of this. See :issue:`1180`.
- libev-cffi: Let the compiler fill in the definition of
nlink_t for st_nlink in struct stat, instead of trying to
guess it ourself. Reported in :issue:`1372` by Andreas
Schwab.
- Remove the Makefile. Its most useful commands, make clean and
make distclean, can now be accomplished in a cross-platform
way using python setup.py clean and python setup.py clean -a,
respectively. The remainder of the Makefile contained Travis
CI commands that have been moved to .travis.yml.
- Deprecate the EMBED and LIBEV_EMBED, etc, build-time
environment variables. Instead, use GEVENTSETUP_EMBED and
GEVENTSETUP_EMBED_LIBEV. See :issue:`1402`.
- The CFFI backends now respect the embed build-time setting.
This allows building the libuv backend without embedding
libuv (except on Windows).
- Support test resources. This allows disabling tests that use
the network. See :ref:`limiting-test-resource-usage` for
more.
- Python 3.7 subprocess: Copy a STARTUPINFO passed as
a parameter. Contributed by AndCycle in :pr:`1352`.
- subprocess: WIFSTOPPED and SIGCHLD are now handled for
determining Popen.returncode. See
https://bugs.python.org/issue29335
- subprocess: No longer close redirected FDs if they are in
pass_fds. This is a bugfix from Python 3.7 applied to all
versions gevent runs on.
- Fix certain operations on a Greenlet in an invalid state
(with an invalid parent) to raise a TypeError sooner rather
than an AttributeError later. This is also slightly faster on
CPython with Cython. Inspired by :issue:`1363` as reported by
Carson Ip. This means that some extreme corner cases that
might have passed by replacing a Greenlet's parent with
something that's not a gevent hub now no longer will.
- Fix: The spawning_stack for Greenlets on CPython should now
have correct line numbers in more cases. See :pr:`1379`.
- The result of gevent.ssl.SSLSocket.makefile() can be used as
a context manager on Python 2.
- Python 2: If the backport of the _thread_ module from futures
has already been imported at monkey-patch time, also patch
this module to be consistent. The pkg_resources package
imports this, and pkg_resources is often imported early on
Python 2 for namespace packages, so if futures is installed
this will likely be the case.
- Python 2: Avoid a memory leak when an io.BufferedWriter is
wrapped around a socket. Reported by Damien Tournoud in
:issue:`1318`.
- Avoid unbounded memory usage when creating very deep spawn
trees. Reported in :issue:`1371` by dmrlawson.
- Win: Make examples/process.py do something useful. See
:pr:`1378` by Robert Iannucci.
- Spawning greenlets can be up to 10% faster. See :pr:`1379`.
- Removed remove-testCongestion.patch which was subsumed in the
upstream tarball.
-------------------------------------------------------------------
Thu Apr 11 14:20:20 UTC 2019 - Matej Cepl <mcepl@suse.com>
- Switch off type_https test as it fails with new Python 2.7.16
- Clean up the SPEC file.
-------------------------------------------------------------------
Mon Feb 18 12:09:52 UTC 2019 - Tomáš Chvátal <tchvatal@suse.com>
- Skip the SSL tests as they just only triggers false positives
with hope upstream sorts it out someday
-------------------------------------------------------------------
Mon Feb 11 11:02:21 UTC 2019 - Tomáš Chvátal <tchvatal@suse.com>
- Switch to pkgconfig requirements as c-ares was renamed between
SLE12 and SLE15
-------------------------------------------------------------------
Mon Feb 4 11:37:48 UTC 2019 - Antonio Larrosa <alarrosa@suse.com>
- Add patches to fix building the package:
* remove-testCongestion.patch to remove a test that is failing
due to a timeout
* fix-tests.patch to fix some tests
- ssl.OP_NO_COMPRESSION is set by default by ssl.
- thread_ident can be represented as a negative hex number now,
so replace the negative sign with the regex too, and not just the number.
* use-libev-cffi.patch, libev-cext seems to be broken on i586, so
use libev-cffi by default (also, the gevent documentation mentions
that upstream will make libev-cffi the default soon).
-------------------------------------------------------------------
Fri Feb 1 10:35:13 UTC 2019 - Tomáš Chvátal <tchvatal@suse.com>
- Make sure to skip tests that need network access
-------------------------------------------------------------------
Thu Jan 31 09:42:44 UTC 2019 - Tomáš Chvátal <tchvatal@suse.com>
- Version update to 1.4.0:
* generate with cython 0.29
* 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.
* Formatting run info no longer includes gevent.local.local objects that have no value in the greenlet. See issue #1275.
* Fixed negative length in pywsgi’s Input read functions for non chunked body. Reported in issue #1274 by tzickel.
* Fix opening files in text mode in CPython 2 on Windows by patching libuv. See issue #1282 reported by wiggin15.
* gevent now depends on greenlet 0.4.14 or above.
* gevent.local.local subclasses correctly supports @staticmethod functions. Reported by Brendan Powers in issue #1266.

Tue Aug 7 15:22:15 UTC 2018 - toddrme2178@gmail.com
- Update to 1.3.5
* Update the bundled libuv from 1.20.1 to 1.22.0.
* Test Python 3.7 on Appveyor. Fix the handling of Popen's
``close_fds`` argument on 3.7.
* Update Python versions tested on Travis, including PyPy to 6.0. See :issue:`1195`.
* :mod:`gevent.queue` imports ``_PySimpleQueue`` instead of
``SimpleQueue`` so that it doesn't block the event loop.
:func:`gevent.monkey.patch_all` makes this same substitution in
:mod:`queue`. This fixes issues with
:class:`concurrent.futures.ThreadPoolExecutor` as well. Reported in
:issue:`1248` by wwqgtxx and :issue:`1251` by pyld.
* :meth:`gevent.socket.socket.connect` doesn't pass the port (service)
to :func:`socket.getaddrinfo` when it resolves an ``AF_INET`` or
``AF_INET6`` address. (The standard library doesn't either.) This
fixes an issue on Solaris. Reported in :issue:`1252` by wiggin15.
* :meth:`gevent.socket.socket.connect` works with more address
families, notably AF_TIPC, AF_NETLINK, AF_BLUETOOTH, AF_ALG and AF_VSOCK.
- Update to 1.3.4
* Be more careful about issuing ``MonkeyPatchWarning`` for ssl
imports. Now, we only issue it if we detect the one specific
condition that is known to lead to RecursionError. This may produce
false negatives, but should reduce or eliminate false positives.
* Based on measurements and discussion in :issue:`1233`, adjust the
way :mod:`gevent.pywsgi` generates HTTP chunks. This is intended to
reduce network overhead, especially for smaller chunk sizes.
* Additional slight performance improvements in :mod:`gevent.pywsgi`.
See :pr:`1241`.
-------------------------------------------------------------------
Wed Jun 13 17:58:41 UTC 2018 - toddrme2178@gmail.com
- Update to 1.3.3
* :func:`gevent.sleep` updates the loop's notion of the current time
before sleeping so that sleep duration corresponds more closely to
elapsed (wall clock) time. :class:`gevent.Timeout` does the same.
Reported by champax and FoP in :issue:`1227`.
* Fix an ``UnboundLocalError`` in SSL servers when wrapping a socket
throws an error. Reported in :issue:`1236` by kochelmonster.
- Update to 1.3.2
* Allow weak refeneces to :class:`gevent.queue.Queue`. Reported in
:issue:`1217` by githrdw.
- Update to 1.3.1
* Allow weak references to :class:`gevent.event.Event`. Reported in
:issue:`1211` by Matias Guijarro.
* Fix embedded uses of :func:`gevent.Greenlet.spawn`, especially under
uwsgi. Reported in :issue:`1212` by Kunal Gangakhedkar.
* Fix :func:`gevent.os.nb_write` and :func:`gevent.os.nb_read` not
always closing the IO event they opened in the event of an
exception. This would be a problem especially for libuv.
- Update to 1.3.0
+ Dependencies
* Cython 0.28.2 is now used to build gevent from a source checkout.
* The bundled libuv is now 1.19.2, up from 1.18.0.
* On Windows, CFFI is now a dependency so that the libuv backend
really can be used by default.
* Cython 0.28b1 or later is now required to build gevent from a source
checkout (Cython is *not* required to build a source distribution
from PyPI).
* Update c-ares to 1.14.0. See :issue:`1105`.
* The bundled libuv is now 1.20.1, up from 1.19.2. See :issue:`1177`.
* gevent now **requires** the patched version of libuv it is
distributed with. Building gevent with a non-embedded libuv, while
not previously supported, is not possible now. See
:issue:`1126`.
* gevent is now built and tested with Cython 0.27. This is required
for Python 3.7 support.
* Update c-ares to 1.13.0. See :issue:`990`.
+ Platform Support
* Travis CI tests on Python 3.7.0b3.
* Windows now defaults to the libuv backend if CFFI is installed. See
:issue:`1163`.
* Python 3.7 passes the automated memory leak checks. See :issue:`1197`.
* Python 3.7.0b4 is now the tested and supported version of Python
3.7. PyPy 6.0 has been tested, although CI continues to use 5.10.
* Travis CI tests on Python 3.7.0b2 and PyPy 2.7 5.10.0 and PyPy 3.5
5.10.1.
* Add initial support for Python 3.7a3. It has the same level of
support as Python 3.6.
> Using unreleased Cython 0.28 and greenlet 0.4.13; requires Python 3.7a3.
> The ``async`` functions and classes have been renamed to
``async_`` due to ``async`` becoming a keyword in Python 3.7.
Aliases are still in place for older versions. See :issue:`1047`.
* gevent is now tested on Python 3.6.4. This includes the following
fixes and changes:
> Errors raised from :mod:`gevent.subprocess` will have a
``filename`` attribute set.
> The :class:`threading.Timer` class is now monkey-patched and can
be joined. Previously on Python 3.4 and above, joining a ``Timer``
would hang the process.
> :meth:`gevent.ssl.SSLSocket.unwrap` behaves more like the standard
library, including returning a SSLSocket and allowing certain
timeout-related SSL errors to propagate. The added standard
library tests ``test_ftplib.py`` now passes.
> :class:`gevent.subprocess.Popen` accepts a "path-like object" for
the *cwd* parameter on all platforms. Previously this only worked
on POSIX platforms under Python 3.6. Now it also works on Windows under
Python 3.6 (as expected) and is backported to all previous versions.
* Linux CI now tests on PyPy3 3.5-5.9.0, updated from PyPy3 3.5-5.7.1.
See :issue:`1001`. PyPy2 has been updated to 5.9.0 from 5.7.1,
Python 2.7 has been updated to 2.7.14 from 2.7.13, Python 3.4 is
updated to 3.4.7 from 3.4.5, Python 3.5 is now 3.5.4 from 3.5.3, and
Python 3.6 is now 3.6.4 from 3.6.0.
* Drop support for Python 3.3. The documentation has only claimed
support for 3.4+ since gevent 1.2 was released, and only 3.4+ has
been tested. This merely removes the supporting Trove classifier and
remaining test code. See :issue:`997`.
* PyPy is now known to run on Windows using the libuv backend, with
caveats. See the section on libuv for more information.
* Due to security concerns, official support for Python 2.7.8 and
earlier (without a modern SSL implementation) has been dropped.
These versions are no longer tested with gevent, but gevent can
still be installed on them. Supporting code will be removed in the
next major version of gevent. See :issue:`1073`.
* `gevent.subprocess.Popen` uses ``/proc/self/fd`` (on Linux) or
``/dev/fd`` (on BSD, including macOS) to find the file descriptors
to close when ``close_fds`` is true. This matches an optimization
added to Python 3 (and backports it to Python 2.7), making process
spawning up to 9 times faster. Also, on Python 3, since Python 3.3
is no longer supported, we can also optimize the case where
``close_fds`` is false (not the default), making process spawning up
to 38 times faster. Initially reported in :issue:`1172` by Ofer Koren.
+ Bug Fixes
* :class:`gevent.local.local` subclasses that mix-in ABCs can be instantiated.
Reported in :issue:`1201` by Bob Jordan.
* Fix a bug detecting whether we can use the memory monitoring
features when psutil is not installed.
* On Python 2, when monkey-patching `threading.Event`, also
monkey-patch the underlying class, ``threading._Event``. Some code
may be type-checking for that. See :issue:`1136`.
* Fix libuv io watchers polling for events that only stopped watchers
are interested in, reducing CPU usage. Reported in :issue:`1144` by
wwqgtxx.
* Fix calling ``shutdown`` on a closed socket. It was raising
``AttributeError``, now it once again raises the correct
``socket.error``. Reported in :issue:`1089` by André Cimander.
* Fix an interpreter crash that could happen if two or more ``loop``
objects referenced the default event loop and one of them was
destroyed and then the other one destroyed or (in the libev C
extension implementation only) deallocated (garbage collected). See
:issue:`1098`.
* Fix a race condition in libuv child callbacks. See :issue:`1104`.
* If a single greenlet created and destroyed many
:class:`gevent.local.local` objects without ever exiting, there
would be a leak of the function objects intended to clean up the
locals after the greenlet exited. Introduce a weak reference to
avoid that. Reported in :issue:`981` by Heungsub Lee.
* pywsgi also catches and ignores by default
:const:`errno.WSAECONNABORTED` on Windows. Initial patch in
:pr:`999` by Jan van Valburg.
* :meth:`gevent.subprocess.Popen.communicate` returns the correct type
of str (not bytes) in universal newline mode under Python 3, or when
an encoding has been specified. Initial patch in :pr:`939` by
William Grzybowski.
* :meth:`gevent.subprocess.Popen.communicate` (and in general,
accessing ``Popen.stdout`` and ``Popen.stderr``) returns the correct
type of str (bytes) in universal newline mode under Python 2.
Previously it always returned unicode strings. Reported in
:issue:`1039` by Michal Petrucha.
* :class:`gevent.fileobject.FileObjectPosix` returns native strings in
universal newline mode on Python 2. This is consistent with what
:class:`.FileObjectThread` does. See :issue:`1039`.
* ``socket.send()`` now catches ``EPROTOTYPE`` on macOS to handle a race
condition during shutdown. Fixed in :pr:`1035` by Jay Oster.
* :func:`gevent.socket.create_connection` now properly cleans up open
sockets if connecting or binding raises a :exc:`BaseException` like
:exc:`KeyboardInterrupt`, :exc:`greenlet.GreenletExit` or
:exc:`gevent.timeout.Timeout`. Reported in :issue:`1044` by
kochelmonster.
+ Enhancements
* Add additional optimizations for spawning greenlets, making it
faster than 1.3a2.
* Use strongly typed watcher callbacks in the libuv CFFI extensions.
This prevents dozens of compiler warnings.
* When gevent prints a timestamp as part of an error message, it is
now in UTC format as specified by RFC3339.
* Threadpool threads that exit now always destroy their hub (if one
was created). This prevents some forms of resource leaks (notably
visible as blocking functions reported by the new monitoring abilities).
* Hub objects now include the value of their ``name`` attribute in
their repr.
* Pools for greenlets and threads have lower overhead, especially for
``map``. See :pr:`1153`.
* The undocumented, internal implementation classes ``IMap`` and
``IMapUnordered`` classes are now compiled with Cython, further
reducing the overhead of ``[Thread]Pool.imap``.
* The classes `gevent.event.Event` and `gevent.event.AsyncResult`
are compiled with Cython for improved performance, as is the
``gevent.queue`` module and ``gevent.hub.Waiter`` and certain
time-sensitive parts of the hub itself. Please report any
compatibility issues.
* ``python -m gevent.monkey <script>`` accepts more values for
``<script>``, including paths to packages or compiled bytecode.
Reported in :issue:`1157` by Eddie Linder.
* Add a simple event framework for decoupled communication. It uses
:mod:`zope.event` if that is installed.
* :mod:`gevent.monkey` has support for plugins in the form of event
subscribers and setuptools entry points. See :pr:`1158` and
:issue:`1162`. setuptools must be installed at runtime for its entry
points to function.
* Add the ``dnspython`` resolver as a lightweight alternative to
c-ares. It is generally faster than c-ares and is supported on PyPy.
c-ares may be deprecated in the future. See :pr:`1088` and
:issue:`1103`.
* Add the module :mod:`gevent.time` that can be imported instead of
:mod:`time`, much like :mod:`gevent.socket` can be imported instead
of :mod:`socket`. It contains ``gevent.sleep``. This aids
monkey-patching.
* Simple subclasses of `gevent.local.local` now have the same
(substantially improved) performance characteristics of plain
`gevent.local.local` itself, making them 2 to 3 times faster than
before. See :pr:`1117`. If there are any compatibility
problems, please open issues.
* Add `gevent.util.assert_switches` to build on the monitoring
functions. Fixes :issue:`1182`.
* A started monitor thread for the active hub now survives a fork. See
:issue:`1185`.
* The greenlet tracer functions used for the various monitoring
capabilities are now compiled with Cython for substantially lower
overhead. See :pr:`1190`.
* libuv now collects all pending watchers and runs their callbacks at
the end of the loop iteration using UV_RUN_ONCE. This eliminates the
need to patch libuv to be greenlet-safe. It also means that
zero-duration timer watchers are actual timer watchers again
(instead of being turned into check watchers); newly added
zero-duration timers cannot block the event loop because they won't
be run until a safe time.
+ Monitoring and Debugging
* Introduce the configuration variable
`gevent.config.track_greenlet_tree` (aka
``GEVENT_TRACK_GREENLET_TREE``) to allow disabling the greenlet tree
features for applications where greenlet spawning is performance
critical. This restores spawning performance to 1.2 levels.
* Add an optional monitoring thread for each hub. When enabled, this
thread (by default) looks for greenlets that block the event loop
for more than 0.1s. You can add your own periodic monitoring
functions to this thread. Set ``GEVENT_MONITOR_THREAD_ENABLE`` to
use it, and ``GEVENT_MAX_BLOCKING_TIME`` to configure the blocking
interval.
* The monitoring thread emits events when it detects certain
conditions, like loop blocked or memory limits exceeded.
* Add settings for monitoring memory usage and emitting events when a
threshold is exceeded and then corrected. gevent currently supplies
no policy for what to do when memory exceeds the configured limit.
``psutil`` must be installed to use this. See :pr:`1150`.
* Greenlet objects now keep track of their spawning parent greenlet
and the code location that spawned them, in addition to maintaining
a "spawn tree local" mapping. This adds some runtime overhead in
relative terms, but absolute numbers are still relatively small.
Based on a proposal from PayPal and comments by Mahmoud Hashemi and
Kurt Rose. See :issue:`755` and :pr:`1115`. As always, feedback is
appreciated.
* Greenlet objects now have a `minimal_ident
<gevent.Greenlet.minimal_ident>` property. It functions
similarly to ``Thread.ident`` or ``id`` by uniquely identifying the
greenlet object while it remains alive, and it can be reused after
the greenlet object is dead. It is different in that it is small and
sequential. Based on a proposal from PayPal and comments by Mahmoud
Hashemi and Kurt Rose. See :issue:`755`. As always, feedback is
appreciated.
* `gevent.Greenlet` objects now have a `gevent.Greenlet.name`
attribute that is included in the default repr.
* Include the values of `gevent.local.local` objects associated with
each greenlet in `gevent.util.format_run_info`.
* Add `gevent.util.GreenletTree` to visualize the greenlet tree. This
is used by `gevent.util.format_run_info`.
+ Build Changes
* Fix building from a source distribution (PyPI) without Cython
installed.
* When building gevent from a source checkout (*not* a distributed
source distribution), ``make`` is no longer required and the
``Makefile`` is not used. Neither is an external ``cython`` command.
Instead, the ``cythonize`` function is used, as recommended by
Cython. (The external commands were never required by source
distributions.) See :issue:`1076`.
* :class:`gevent.local.local` is compiled with Cython on CPython.
* The Cython ares 'channel' class is no longer declared to be publicly
accessible from a named C structure. Doing so caused a conflict with
the c-ares header files.
* Update autoconf's config.guess and config.sub to the latest versions
for c-ares and libev.
+ Subprocess
* Make :class:`gevnt.subprocess.Popen` accept the ``restore_signals``
keyword argument on all versions of Python, and on Python 2 have it
default to false. It previously defaulted to true on all versions;
now it only defaults to true on Python 3. The standard library in
Python 2 does not have this argument and its behaviour with regards
to signals is undocumented, but there is code known to rely on
signals not being restored under Python 2. Initial report and patch
in :pr:`1063` by Florian Margaine.
* Allow :class:`gevent.subprocess.Popen` to accept the keyword
arguments ``pass_fds`` and ``start_new_session`` under Python 2.
They have always had the same default as Python 3, namely an empty
tuple and false, but now are accessible to Python 2.
* Support the ``capture_output`` argument added to Python 3.7 in
:func:`gevent.subprocess.run`.
+ Configuration
* Centralize all gevent configuration in an object at
``gevent.config``, allowing for gevent to be configured through code
and not *necessarily* environment variables, and also provide a
centralized place for documentation. See :issue:`1090`.
> The new ``GEVENT_CORE_CFFI_ONLY`` environment variable has been
replaced with the pre-existing ``GEVENT_LOOP`` environment
variable. That variable may take the values ``libev-cext``,
``libev-cffi``, or ``libuv-cffi``, (or be a list in preference
order, or be a dotted name; it may also be assigned to an
object in Python code at ``gevent.config.loop``).
> The ``GEVENTARES_SERVERS`` environment variable is deprecated in
favor of ``GEVENT_RESOLVER_SERVERS``. See :issue:`1103`.
+ Other Changes
* The internal, undocumented module ``gevent._threading`` has been
simplified.
* The internal, undocumented class ``gevent._socket3._fileobject`` has
been removed. See :issue:`1084`.
* Simplify handling of the libev default loop and the ``destroy()``
method. The default loop, when destroyed, can again be requested and
it will regenerate itself. The default loop is the only one that can
receive child events.
* Make :meth:`gevent.socket.socket.sendall` up to ten times faster on
PyPy3, through the same change that was applied in gevent 1.1b3 for PyPy2.
* Be more careful about issuing a warning about patching SSL on
Python 2. See :issue:`1108`.
* Signal handling under PyPy with libuv is more reliable. See
:issue:`1112`.
* The :mod:`gevent.greenlet` module is now compiled with Cython to
offset any performance decrease due to :issue:`755`. Please open
issues for any compatibility concerns. See :pr:`1115` and :pr:`1120`.
* On CPython, allow the pure-Python implementations of
`gevent.Greenlet`, `gevent.local` and `gevent.lock` to be
used when the environment variable ``PURE_PYTHON`` is set. This is
not recommended except for debugging and testing. See :issue:`1118`.
* :meth:`gevent.select.poll.poll` now interprets a *timeout* of -1 the
same as a *timeout* of *None* as the standard requires. Previously,
on libuv this was interpreted the same as a *timeout* of 0. In
addition, all *timeout* values less than zero are interpreted like
*None* (as they always were under libev). See :issue:`1127`.
* Monkey-patching now defaults to patching ``threading.Event``.
* ``Pool.add`` now accepts ``blocking`` and ``timeout`` parameters,
which function similarly to their counterparts in ``Semaphore``.
See :pr:`1032` by Ron Rothman.
* Defer adjusting the stdlib's list of active threads until
``threading`` is monkey patched. Previously this was done when
:mod:`gevent.threading` was imported. That module is documented to
be used as a helper for monkey patching, so this should generally
function the same, but some applications ignore the documentation
and directly import that module anyway.
A positive consequence is that ``import gevent.threading, threading;
threading.current_thread()`` will no longer return a DummyThread
before monkey-patching. Another positive consequence is that PyPy
will no longer print a ``KeyError`` on exit if
:mod:`gevent.threading` was imported *without* monkey-patching.
See :issue:`984`.
* Specify the Requires-Python metadata for improved installation
support in certain tools (setuptools v24.2.1 or newer is required).
See :issue:`995`.
* Monkey-patching after the :mod:`ssl` module has been imported now
prints a warning because this can produce ``RecursionError``.
* :class:`gevent.local.local` objects are now approximately 3.5 times faster
getting, setting and deleting attributes on PyPy. This involved
implementing more of the attribute protocols directly. Please open
an issue if you have any compatibility problems. See :issue:`1020`.
* :class:`gevent.local.local` is compiled with Cython on CPython. It
was already 5 to 6 times faster due to the work on :issue:`1020`,
and compiling it with Cython makes it another 5 to 6 times faster,
for a total speed up of about 35 times. It is now in the same
ballpark as the native :class:`threading.local` class. It also uses
one pointer less memory per object, and one pointer less memory per
greenlet. See :pr:`1024`.
* More safely terminate subprocesses on Windows with
:meth:`gevent.subprocess.Popen.terminate`. Reported in :issue:`1023`
by Giacomo Debidda.
* gevent now uses cffi's "extern 'Python'" callbacks. These should be
faster and more stable. This requires at least cffi 1.4.0. See :issue:`1049`.
* gevent now approximately tries to stick to a scheduling interval
when running callbacks, instead of simply running a count of
callbacks. The interval is determined by
:func:`gevent.getswitchinterval`. On Python 3, this is the same as
the thread switch interval. On Python 2, this defaults to 0.005s and
can be changed with :func:`gevent.setswitchinterval`. This should
result in more fair "scheduling" of greenlets, especially when
``gevent.sleep(0)`` or other busy callbacks are in use. The interval
is checked every 50 callbacks to keep overhead low. See
:issue:`1072`. With thanks to Arcadiy Ivanov and Antonio Cuni.
* The long-deprecated and undocumented module ``gevent.wsgi`` was removed.
+ libuv
* Add initial *experimental* support for using libuv as a backend
instead of libev, controlled by setting the environment variable
``GEVENT_CORE_CFFI_ONLY=libuv`` before importing gevent. This
suffers a number of limitations compared to libev, notably:
> libuv support is not available in the manylinux wheels uploaded to
PyPI. The manylinux specification requires glibc 2.5, while libuv
requires glibc 2.12. Install from source to access libuv on Linux
(e.g., pip's ``--no-binary`` option).
> Timers (such as ``gevent.sleep`` and ``gevent.Timeout``) only
support a resolution of 1ms (in practice, it's closer to 1.5ms).
Attempting to use something smaller will automatically increase it
to 1ms and issue a warning. Because libuv only supports
millisecond resolution by rounding a higher-precision clock to an
integer number of milliseconds, timers apparently suffer from more
jitter.
> Using negative timeouts may behave differently from libev.
> libuv blocks delivery of all signals, so signals are handled using
an (arbitrary) 0.3 second timer. This means that signal handling
will be delayed by up to that amount, and that the longest the
event loop can sleep in the operating system's ``poll`` call is
that amount. Note that this is what gevent does for libev on
Windows too.
> libuv only supports one io watcher per file descriptor, whereas
libev and gevent have always supported many watchers using
different settings. The libev behaviour is emulated at the Python
level, but that adds overhead.
> Looping multiple times and expecting events for the same file
descriptor to be raised each time without any data being read or
written (as works with libev) does not appear to work correctly on
Linux when using ``gevent.select.poll`` or a monkey-patched
``selectors.PollSelector``.
> The build system does not support using a system libuv; the
embedded copy must be used. Using setuptools to compile libuv was
the most portable method found.
> If anything unexpected happens, libuv likes to ``abort()`` the
entire process instead of reporting an error. For example, closing
a file descriptor it is using in a watcher may cause the entire
process to be exited.
> There may be occasional otherwise unexplained and hard to
duplicate crashes. If you can duplicate a crash, **please** submit
an issue.
> This is the only backend that PyPy can use on Windows. As of this
alpha, there are many known issues with non-blocking sockets
(e.g., as used by :mod:`asyncore`; see ``test_ftplib.py``) and
sometimes sockets not getting closed in a timely fashion
(apparently; see ``test_httpservers.py``) and communicating with
subprocesses (it always hangs). Help tracking those down would be
appreciated. Only PyPy2 is tested.
Other differences include:
> The order in which timers and other callbacks are invoked may be
different than in libev. In particular, timers and IO callbacks
happen in a different order, and timers may easily be off by up to
half of the supposed 1ms resolution. See :issue:`1057`.
> Starting a ``timer`` watcher does not update the loop's time by
default. This is because, unlike libev, a timer callback can cause
other timer callbacks to be run if they expire because the loop's
time updated, without cycling the event loop. See :issue:`1057`.
libev has also been changed to follow this behaviour.
Also see :issue:`1072`.
> Timers of zero duration do not necessarily cause the event loop to
cycle, as they do in libev. Instead, they may be called
immediately. If zero duration timers are added from other zero
duration timer callbacks, this can lead the loop to appear to
hang, as no IO will actually be done.
To mitigate this issue, ``loop.timer()`` detects attempts to use
zero duration timers and turns them into a check watcher. check
watchers do not support the ``again`` method.
> All watchers (e.g., ``loop.io``) and the ``Timeout`` class have a
``close`` method that should be called when code is done using the
object (they also function as context managers and a ``with``
statement will automatically close them). gevent does this
internally for sockets, file objects and internal timeouts.
Neglecting to close an object may result in leaking native
resources. To debug this, set the environment variables
``GEVENT_DEBUG=debug`` and ``PYTHONTRACEMALLOC=n`` before starting
the process.
The traditional cython-based libev backend will not leak if
``close`` is not called and will not produce warnings. The
CFFI-based libev backend will not currently leak but will produce
warnings. The CFFI-based libuv backend may leak and will produce
warnings.
Again, this is extremely experimental and all of it is subject to
change.
See :issue:`790` for history and more in-depth discussion.
+ libev
* The C extension has been updated to use more modern Cython idioms
and generate less code for simplicity, faster compilation and better
cache usage. See :pr:`1077`.
> Watcher objects may be slightly larger. On a 64-bit platform, a
typical watcher may be 16 bytes (2 pointers) larger. This is
offset by slight performance gains.
> Cython is no longer preprocessed. Certain attributes that were
previously only defined in certain compilation modes (notably
LIBEV_EMBED) are now always defined, but will raise
``AttributeError`` or have a negative value when not available. In
general these attributes are not portable or documented and are
not implemented by libuv or the CFFI backend. See :issue:`1076`.
> Certain private helper functions (``gevent_handle_error``, and part of
``gevent_call``) are now implemented in Cython instead of C. This
reduces our reliance on internal undocumented implementation
details of Cython and Python that could change. See :pr:`1080`.

- specfile:
* added CHANGES.rst CONTRIBUTING.rst to %doc
- update to version 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.

- Update to version 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`.
- Update to version 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`.
- Update to version 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.
- Update to version 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.

Tue Dec 13 14:46:50 UTC 2016 - dmueller@suse.com
- update to 1.1.2:
* Python 2: ``sendall`` on a non-blocking socket could spuriously fail
with a timeout.
* 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.
* :class:`selectors.SelectSelector` is properly monkey-patched
regardless of the order of imports. Reported in :issue:`835` by
Przemysław Węgrzyn.
* Python 2: ``reload(site)`` no longer fails with a ``TypeError`` if
gevent has been imported. Reported in :issue:`805` by Jake Hilton.
* Nested callbacks that set and clear an Event no longer cause
``wait`` to return prematurely. Reported in :issue:`771` by Sergey
Vasilyev.
* Fix build on Solaris 10. Reported in :issue:`777` by wiggin15.
* The ``ref`` parameter to :func:`gevent.os.fork_and_watch` was being ignored.
* Python 3: :class:`gevent.queue.Channel` is now correctly iterable, instead of
raising a :exc:`TypeError`.
* Python 3: Add support for :meth:`socket.socket.sendmsg`,
:meth:`socket.socket.recvmsg` and :meth:`socket.socket.recvmsg_into`
on platforms where they are defined. Initial :pr:`773` by Jakub
Klama.
