File python-gevent.changes of Package python-gevent
-------------------------------------------------------------------
Wed Oct 23 11:07:00 UTC 2024 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to 24.10.3
* Fix clearing stack frames on Python 3.13. This is invoked when you
fork after having used the thread pool.
* Distribute manylinux2014 wheels for x86_64.
* Stop switching to the hub in the after fork hook in a child process.
This could lead to strange behaviour, and is different than what all
other versions of Python do.
- from version 24.10.2
* Workaround a Cython bug compiling on GCC14.
- Drop gh-2031-cython-workaround.patch, merged upstream
-------------------------------------------------------------------
Thu Oct 10 09:39:52 UTC 2024 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to 24.10.1
* Update the bundled c-ares to 1.33.1.
* Add support for Python 3.13.
- The functions and classes in ``gevent.subprocess`` no longer accept
``stdout=STDOUT`` and raise a ``ValueError``.
Several additions and changes to the ``queue`` module, including:
- ``Queue.shutdown`` is available on all versions of Python.
- ``LifoQueue`` is now a joinable queue.
* gevent.monkey changed from a module to a package. The public API
remains the same.
For this release, private APIs (undocumented, marked internal, or
beginning with an underscore) are also preserved. However, these may
be changed or removed at any time in the future. If you are using one
of these APIs and cannot replace it, please contact the gevent team.
* For platforms that don't have ``socketpair``, upgrade our fallback
code to avoid a security issue.
See :issue:`2048`.
* Remove support for Python 3.8, which has reached the end of its
support lifecycle.
See :issue:`remove_py38`.
- Drop gh-113964-fix-tests-3.12.3.patch, fixed upstream
- Renumber patches
-------------------------------------------------------------------
Tue May 28 10:56:43 UTC 2024 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Add gh-2031-cython-workaround.patch which fixes a regression
with Cython 3.0.10 which caused an FTBFS with GCC 14
-------------------------------------------------------------------
Mon Apr 22 07:38:07 UTC 2024 - Daniel Garcia <daniel.garcia@suse.com>
- Add gh-113964-fix-tests-3.12.3.patch to tix tests with python 3.12.3
(bsc#1223128)
- Drop upstream patches:
* gevent-fix-unittest-returncode-py312-c1.patch
* gevent-fix-unittest-returncode-py312-c2.patch
- Update to version 24.2.1:
- Add support for Python patch releases 3.11.8 and 3.12.2, which
changed internal details of threading.
- Errors raised from subprocess.Popen may not have a filename set.
- SSLSocket.recv_into and SSLSocket.read no longer require the
buffer to implement len and now work with buffers whose size is
not 1.
- gh-108310: Fix CVE-2023-40217: Check for & avoid the ssl pre-close
flaw.
- Drop setuptools to a soft test dependency.
- Drop support for very old versions of CFFI.
- Update bundled c-ares from 1.19.1 to 1.26.0.
- Locks created by gevent, but acquired from multiple different
threads (not recommended), no longer spin to implement timeouts
and interruptible blocking. Instead, they use the native
functionality of the Python 3 lock. This may improve some
scenarios. See issue #2013.
-------------------------------------------------------------------
Wed Jan 10 22:40:39 UTC 2024 - Ben Greiner <code@bnavigator.de>
- Clean obsolete old python and old distribution directives
* Only 15.5+ with the sle15 python module and Tumbleweed have the
required Python 3.8+
* Drop fix-no-return-in-nonvoid-function.patch
- Update test suite execution
* Use -u-network flag to disable network tests
* Add gevent-opensuse-nocolor-tests.patch -- Avoid colorization
of test output in obs runners
* Add gevent-fix-unittest-returncode-py312-c1.patch and
gevent-fix-unittest-returncode-py312-c2.patch
gh#gevent/gevent#2012
-------------------------------------------------------------------
Mon Nov 27 15:53:52 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 23.9.1:
* Require greenlet 3.0 on Python 3.11 and Python 3.12; greenlet
3.0 is recommended for all platforms.
-------------------------------------------------------------------
Mon Sep 18 19:07:56 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 23.9.0 (bsc#1215469, CVE-2023-41419):
* Make ``gevent.select.select`` accept arbitrary iterables, not
just sequences. That is, you can now pass in a generator of file
descriptors instead of a realized list. Internally, arbitrary
iterables are copied into lists. This better matches what the
standard library does.
* On Python 3.11 and newer, opt out of Cython's fast exception
manipulation, which *may* be causing problems in certain
circumstances when combined with greenlets.
* On all versions of Python, adjust some error handling in the
default * -based loop. This fixes several assertion failures
on debug versions of CPython. Hopefully it has a positive
impact under real conditions.
* Make ``gevent.pywsgi`` comply more closely with the HTTP
specification for chunked transfer encoding. In particular,
we are much stricter about trailers, and trailers that are
invalid (too long or featuring disallowed characters) forcibly
close the connection to the client *after* the results have
been sent.
* Trailers otherwise continue to be ignored and are not
available to the WSGI application.
Previously, carefully crafted invalid trailers in chunked
requests on keep-alive connections might appear as two
requests to ``gevent.pywsgi``. Because this was handled
exactly as a normal keep-alive connection with two requests,
the WSGI application should handle it normally. However, if
you were counting on some upstream server to filter incoming
requests based on paths or header fields, and the upstream
server simply passed trailers through without
validating them, then this embedded second request would
bypass those checks.
(If the upstream server validated that the trailers
meet the* HTTP specification, this could not occur,
because characters that are required in an HTTP request,
like a space, are not allowed in trailers.) CVE-2023-41419
was reserved for this.
-------------------------------------------------------------------
Mon Aug 14 09:20:19 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 23.7.0:
* Add preliminary support for Python 3.12, using greenlet
3.0a1.
* Update the bundled c-ares version to 1.19.1.
* Fix an edge case connecting a non-blocking ``SSLSocket`` that
could result in an AttributeError. In a change to match
the standard library, calling ``sock.connect_ex()`` on a
subclass of ``socket`` no longer calls the subclass's
``connect`` method.
* Make gevent's ``FileObjectThread`` (mostly used on Windows)
implement ``readinto`` cooperatively.
* Work around an ``AttributeError`` during cyclic garbage
collection when Python finalizers (``__del__`` and the like)
attempt to use gevent APIs. This is not a recommended practice,
and it is unclear if catching this ``AttributeError`` will fix
any problems or just shift them.
* Remove support for obsolete Python versions. This is
everything prior to 3.8.
* Stop using ``pkg_resources`` to find entry points (plugins).
Instead, use ``importlib.metadata``.
* Honor ``sys.unraisablehook`` when a callback function
produces an exception, and handling the exception in the hub
*also* produces an exception.
- drop skip-tests-in-leap.patch handle-python-ssl-changes.patch (obsolete)
-------------------------------------------------------------------
Fri Jun 9 08:08:57 UTC 2023 - Daniel Garcia <daniel.garcia@suse.com>
- skip test__util.py in s390x arch
bsc#1211861
-------------------------------------------------------------------
Thu Jun 1 07:05:01 UTC 2023 - Dirk Müller <dmueller@suse.com>
- handle-python-ssl-changes.patch: refresh to handle ssl.shared_ciphers()
behavior change in python 3.11 as well
-------------------------------------------------------------------
Mon May 15 14:18:03 UTC 2023 - Steve Kowalik <steven.kowalik@suse.com>
- Add patch handle-python-ssl-changes.patch:
* Handle Python 3.10 changes where ssl.shared_ciphers() changes
behaviour.
-------------------------------------------------------------------
Mon May 15 13:44:48 UTC 2023 - Dirk Müller <dmueller@suse.com>
- skip one more test from testsuite
-------------------------------------------------------------------
Thu May 4 20:28:36 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 22.10.2:
* Update to greenlet 2.0. This fixes a deallocation issue that
required a change in greenlet's ABI. The design of greenlet 2.0 is
intended to prevent future fixes and enhancements from
requiring an ABI change, making it easier to update gevent
and greenlet independently.
-------------------------------------------------------------------
Sun Apr 23 23:15:24 UTC 2023 - Matej Cepl <mcepl@suse.com>
- Switch documentation to be within the main package.

- Make calling of %{sle15modernpython} optional.
-------------------------------------------------------------------
Wed Mar 8 15:30:19 UTC 2023 - Matej Cepl <mcepl@suse.com>
- Clean up the SPEC file.
-------------------------------------------------------------------
Sun Oct 16 17:41:54 UTC 2022 - Dirk Müller <dmueller@suse.com>
- update to 22.10.0:
* Update bundled libuv to 1.44.2.
See :issue:`1913`.
* Upgrade embedded c-ares to 1.18.1.
* Upgrade bundled libuv to 1.42.0 from 1.40.0.
* Added preliminary support for Python 3.11 (rc2 and later).
Some platforms may or may not have binary wheels at this time.
.. important:: Support for legacy versions of Python, including 2.7
and 3.6, will be ending soon. The
maintenance burden has become too great and the
maintainer's time is too limited.
Ideally, there will be a release of gevent compatible
with a final release of greenlet 2.0 that still
supports those legacy versions, but that may not be
possible; this may be the final release to support them.
:class:`gevent.threadpool.ThreadPool` can now optionally expire idle
threads. This is used by default in the implicit thread pool used for
DNS requests and other user-submitted tasks; other uses of a
thread-pool need to opt-in to this.
See :issue:`1867`.
* Truly disable the effects of compiling with ``-ffast-math``.
-------------------------------------------------------------------
Mon Dec 13 20:30:19 UTC 2021 - Ben Greiner <code@bnavigator.de>
- Update to 21.12.0
* Fix hanging the interpreter on shutdown if gevent monkey
patching occurred on a non-main thread in Python 3.9.8 and
above. (Note that this is not a recommended practice.) See
:issue:`1839`.
* Update the embedded c-ares from 1.16.1 to 1.17.1. See
:issue:`1758`.
* Add support for Python 3.10rc1 and newer. As part of this, the
minimum required greenlet version was increased to 1.1.0 (on
CPython), and the minimum version of Cython needed to build
gevent from a source checkout is 3.0a9. Note that the dnspython
resolver is not available on Python 3.10. See :issue:`1790`.
- Meanwhile Cython 0.29.24 and dnspython are compatible
with python310
- Revert threading test skip, fixed in 21.12
-------------------------------------------------------------------
Fri Nov 19 07:48:57 UTC 2021 - Steve Kowalik <steven.kowalik@suse.com>
- Skip test__threading_monkey_in_thread as it breaks with Python 3.9.9.
-------------------------------------------------------------------
Thu Jul 8 05:50:58 UTC 2021 - Antonio Larrosa <alarrosa@suse.com>
- Skip two tests that fail in SLE/Leap:
* skip-tests-in-leap.patch
-------------------------------------------------------------------
Fri Feb 12 10:18:37 UTC 2021 - Pedro Monreal <pmonreal@suse.com>
- Relax the crypto policies for the test-suite
-------------------------------------------------------------------
Fri Feb 12 10:10:53 UTC 2021 - Pedro Monreal <pmonreal@suse.com>
- Update to 21.1.2:
* Features:
- Update the embedded libev from 4.31 to 4.33.
- Update the embedded libuv from 1.38.0 to 1.40.0.
- Update to 21.1.1:
* Bugfixes:
- Fix a TypeError on startup on Python 2 with zope.schema
installed.
- Update to 21.1.0:
* Bugfixes:
- Make gevent FileObjects more closely match the semantics of
native file objects for the name attribute.: Objects opened
from a file descriptor integer have that integer as their
name. (Note that this is the Python 3 semantics; Python 2
native file objects returned from os.fdopen() have the string
"<fdopen>" as their name , but here gevent always follows
Python 3.) The name remains accessible after the file object
is closed.
* Misc:
- Make gevent.event.AsyncResult print a warning when it detects
improper cross-thread usage instead of hanging.
- AsyncResult has never been safe to use from multiple threads.
It, like most gevent objects, is intended to work with greenlets
from a single thread. Using AsyncResult from multiple threads
has undefined semantics. The safest way to communicate between
threads is using an event loop async watcher.
- Those undefined semantics changed in recent gevent versions,
making it more likely that an abused AsyncResult would
misbehave in ways that could cause the program to hang.
- Now, when AsyncResult detects a situation that would hang, it
prints a warning to stderr. Note that this is best-effort, and
hangs are still possible, especially under PyPy 7.3.3.
- At the same time, AsyncResult is tuned to behave more like it
did in older versions, meaning that the hang is once again much
less likely. If you were getting lucky and using AsyncResult
successfully across threads, this may restore your luck. In
addition, cross-thread wakeups are faster. Note that the gevent
hub now uses an extra file descriptor to implement this.
- Similar changes apply to gevent.event.Event
- Update to 20.12.1:
* Features:
- Make :class:`gevent.Greenlet` objects function as context
managers. When the with suite finishes, execution doesn't
continue until the greenlet is finished. This can be a simpler
alternative to a :class:`gevent.pool.Group` when the lifetime
of greenlets can be lexically scoped.
* Bugfixes:
- Make gevent's Semaphore objects properly handle native thread
identifiers larger than can be stored in a C long on Python 3,
instead of raising an OverflowError.
- Rebase fix-no-return-in-nonvoid-function.patch
-------------------------------------------------------------------
Tue Feb 9 21:32:04 UTC 2021 - Dirk Müller <dmueller@suse.com>
- update to 20.12.0:
* Make worker threads created by :class:`gevent.threadpool.ThreadPool` install
the :func:`threading.setprofile` and :func:`threading.settrace` hooks
while tasks are running. This provides visibility to profiling and
tracing tools like yappi.
* Incorrectly passing an exception *instance* instead of an exception
*type* to `gevent.Greenlet.kill` or `gevent.killall` no longer prints
an exception to stderr.
* Make destroying a hub try harder to more forcibly stop loop processing
when there are outstanding callbacks or IO operations scheduled.
* Improve the ability to use monkey-patched locks, and
`gevent.lock.BoundedSemaphore`, across threads, especially when the
various threads might not have a gevent hub or any other active
greenlets. In particular, this handles some cases that previously
raised ``LoopExit`` or would hang. Note that this may not be reliable
on PyPy on Windows; such an environment is not currently recommended.
* Make error reporting when a greenlet suffers a `RecursionError` more
reliable.
* gevent.pywsgi: Avoid printing an extra traceback ("TypeError: not
enough arguments for format string") to standard error on certain
invalid client requests.
* Add support for PyPy2 7.3.3.
* Python 2: Make ``gevent.subprocess.Popen.stdin`` objects have a
``write`` method that guarantees to write the entire argument in
binary, unbuffered mode. This may require multiple trips around the
event loop, but more closely matches the behaviour of the Python 2
standard library (and gevent prior to 1.5). The number of bytes
written is still returned (instead of ``None``).
See :issue:`1711`.
* Make `gevent.pywsgi` stop trying to enforce the rules for reading chunked input or
``Content-Length`` terminated input when the connection is being
upgraded, for example to a websocket connection. Likewise, if the
protocol was switched by returning a ``101`` status, stop trying to
automatically chunk the responses.
* Remove the ``__dict__`` attribute from `gevent.socket.socket` objects. The
standard library socket do not have a ``__dict__``.
-------------------------------------------------------------------
Fri Dec 11 23:52:16 UTC 2020 - Matej Cepl <mcepl@suse.com>
- mock dependency was actually not needed at all
-------------------------------------------------------------------
Thu Oct 8 10:03:45 UTC 2020 - Hans-Peter Jansen <hpj@urpla.net>
- Disable more tests failing for Python 3.6
- Don't bother with python2 tests
-------------------------------------------------------------------
Sat Oct 3 16:09:59 UTC 2020 - Hans-Peter Jansen <hpj@urpla.net>
- Update to version 20.9.0 (2020-09-22)
+ Features
* The embedded libev is now asked to detect the availability of
clock_gettime and use the realtime and/or monotonic clocks,
if they are available.
* On Linux, this can reduce the number of system calls libev
makes. Originally provided by Josh Snyder. See
:issue:`issue1648`.
+ Bugfixes
* On CPython, depend on greenlet >= 0.4.17. This version is
binary incompatible with earlier releases on CPython 3.7 and
later.
* On Python 3.7 and above, the module gevent.contextvars is no
longer monkey-patched into the standard library. contextvars
are now both greenlet and asyncio task local. See
:issue:`1656`. See :issue:`issue1674`.
* The DummyThread objects created automatically by certain
operations when the standard library threading module is
monkey-patched now match the naming convention the standard
library uses ("Dummy-12345"). Previously (since gevent 1.2a2)
they used "DummyThread-12345". See :issue:`1659`.
* Fix compatibility with dnspython 2.
* Caution!
* This currently means that it can be imported. But it cannot
yet be used. gevent has a pinned dependency on dnspython < 2
for now.
* See :issue:`1661`.
- Update to version 20.6.2 (2020-06-16)
+ Features
* It is now possible to build and use the embedded libuv on a
Cygwin platform.
* Note that Cygwin is not an officially supported platform of
upstream libuv and is not tested by gevent, so the actual
working status is unknown, and this may bitrot in future
releases.
* Thanks to berkakinci for the patch. See :issue:`issue1645`.
+ Bugfixes
* Relax the version constraint for psutil on PyPy.
* Previously it was pinned to 5.6.3 for PyPy2, except for on
Windows, where it was excluded. It is now treated the same as
CPython again. See :issue:`issue1643`.
- Update to version 20.6.1 (2020-06-10)
+ Features
* gevent's CI is now tested on Ubuntu 18.04 (Bionic), an
upgrade from 16.04 (Xenial). See :issue:`1623`.
+ Bugfixes
* On Python 2, the dnspython resolver can be used without
having selectors2 installed. Previously, an ImportError would
be raised. See :issue:`issue1641`.
* Python 3 gevent.ssl.SSLSocket objects no longer attempt to
catch ConnectionResetError and treat it the same as an
SSLError with SSL_ERROR_EOF (typically by suppressing it).
* This was a difference from the way the standard library
behaved (which is to raise the exception). It was added to
gevent during early testing of OpenSSL 1.1 and TLS 1.3. See
:issue:`1637`.
- Update to version 20.6.0 (2020-06-06)
+ Features
* Add gevent.selectors containing GeventSelector. This selector
implementation uses gevent details to attempt to reduce
overhead when polling many file descriptors, only some of
which become ready at any given time.
* This is monkey-patched as selectors.DefaultSelector by
default.
* This is available on Python 2 if the selectors2 backport is
installed. (This backport is installed automatically using
the recommended extra.) When monkey-patching, selectors is
made available as an alias to this module. See :issue:`1532`.
* Depend on greenlet >= 0.4.16. This is required for CPython
3.9 and 3.10a0. See :issue:`1627`.
* Add support for Python 3.9.
* No binary wheels are available yet, however. See
:issue:`1628`.
+ Bugfixes
* gevent.socket.create_connection and
gevent.socket.socket.connect no longer ignore IPv6 scope IDs.
* Any IP address (IPv4 or IPv6) is no longer subject to an
extra call to getaddrinfo. Depending on the resolver in use,
this is likely to change the number and order of greenlet
switches. (On Windows, in particular test cases when there
are no other greenlets running, it has been observed to lead
to LoopExit in scenarios that didn't produce that before.)
See :issue:`1634`.
- Update to version 20.5.2 (2020-05-28)
+ Bugfixes
* Forking a process that had use the threadpool to run tasks
that created their own hub would fail to clean up the
threadpool by raising greenlet.error. See :issue:`1631`.
- Update to version 20.5.1 (2020-05-26)
+ Features
* Waiters on Event and Semaphore objects that call wait() or
acquire(), respectively, that find the Event already set, or
the Semaphore available, no longer "cut in line" and run
before any previously scheduled greenlets. They now run in
the order in which they arrived, just as waiters that had to
block in those methods do. See :issue:`1520`.
* Update tested PyPy version from 7.3.0 to 7.3.1 on Linux. See
:issue:`1569`.
* Make zope.interface, zope.event and (by extension) setuptools
required dependencies. The events install extra now does
nothing and will be removed in 2021. See :issue:`1619`.
* Update bundled libuv from 1.36.0 to 1.38.0. See
:issue:`1621`.
* Update bundled c-ares from 1.16.0 to 1.16.1.
* On macOS, stop trying to adjust c-ares headers to make them
universal. See :issue:`1624`.
+ Bugfixes
* Make gevent locks that are monkey-patched usually work across
native threads as well as across greenlets within a single
thread. Locks that are only used in a single thread do not
take a performance hit. While cross-thread locking is
relatively expensive, and not a recommended programming
pattern, it can happen unwittingly, for example when using
the threadpool and logging.
* Before, cross-thread lock uses might succeed, or, if the lock
was contended, raise greenlet.error. Now, in the contended
case, if the lock has been acquired by the main thread at
least once, it should correctly block in any thread,
cooperating with the event loop of both threads. In certain
(hopefully rare) cases, it might be possible for contended
case to raise LoopExit when previously it would have raised
greenlet.error; if these cases are a practical concern,
please open an issue.
* Also, the underlying Semaphore always behaves in an atomic
fashion (as if the GIL was not released) when PURE_PYTHON is
set. Previously, it only correctly did so on PyPy. See
:issue:`issue1437`.
* Rename gevent's C accelerator extension modules using a
prefix to avoid clashing with other C extensions. See
:issue:`1480`.
* Using gevent.wait on an Event more than once, when that Event
is already set, could previously raise an AssertionError.
* As part of this, exceptions raised in the main greenlet will
now include a more complete traceback from the failing
greenlet. See :issue:`1540`.
* Avoid closing the same Python libuv watcher IO object twice.
Under some circumstances (only seen on Windows), that could
lead to program crashes. See :issue:`1587`.
* gevent can now be built using Cython 3.0a5 and newer. The
PyPI distribution uses this version.
* The libev extension was incompatible with this. As part of
this, certain internal, undocumented names have been changed.
* (Technically, gevent can be built with Cython 3.0a2 and
above. However, up through 3.0a4 compiling with Cython 3
results in gevent's test for memory leaks failing. See this
Cython issue.) See :issue:`1599`.
* Destroying a hub after joining it didn't necessarily clean up
all resources associated with the hub, especially if the hub
had been created in a secondary thread that was exiting. The
hub and its parent greenlet could be kept alive.
* Now, destroying a hub drops the reference to the hub and
ensures it cannot be switched to again. (Though using a new
blocking API call may still create a new hub.)
* Joining a hub also cleans up some (small) memory resources
that might have stuck around for longer before as well. See
:issue:`1601`.
* Fix some potential crashes under libuv when using
gevent.signal_handler. The crashes were seen running the test
suite and were non-deterministic. See :issue:`1606`.
- Update to version 20.5.0 (2020-05-01)
+ Features
* Update bundled c-ares to version 1.16.0. Changes. See
:issue:`1588`.
* Update all the bundled config.guess and config.sub scripts.
See :issue:`1589`.
* Update bundled libuv from 1.34.0 to 1.36.0. See
:issue:`1597`.
+ Bugfixes
* Use ares_getaddrinfo instead of a manual lookup.
* This requires c-ares 1.16.0.
* Note that this may change the results, in particular their
order.
* As part of this, certain parts of the c-ares extension were
adapted to use modern Cython idioms.
* A few minor errors and discrepancies were fixed as well, such
as gethostbyaddr('localhost') working on Python 3 and failing
on Python 2. The DNSpython resolver now raises the expected
TypeError in more cases instead of an AttributeError. See
:issue:`1012`.
* The c-ares and DNSPython resolvers now raise exceptions much
more consistently with the standard resolver. Types and
errnos are substantially more likely to match what the
standard library produces.
* Depending on the system and configuration, results may not
match exactly, at least with DNSPython. There are still some
rare cases where the system resolver can raise herror but
DNSPython will raise gaierror or vice versa. There doesn't
seem to be a deterministic way to account for this. On PyPy,
getnameinfo can produce results when CPython raises
socket.error, and gevent's DNSPython resolver also raises
socket.error.
* In addition, several other small discrepancies were
addressed, including handling of localhost and broadcast host
names.
* Note
* This has been tested on Linux (CentOS and Ubuntu), macOS, and
Windows. It hasn't been tested on other platforms, so results
are unknown for them. The c-ares support, in particular, is
using some additional socket functions and defines. Please
let the maintainers know if this introduces issues.
* See :issue:`1459`.
- Update to version 20.04.0 (2020-04-22)
+ Features
* Let CI (Travis and Appveyor) build and upload release wheels
for Windows, macOS and manylinux. As part of this, (a subset
of) gevent's tests can run if the standard library's
test.support module has been stripped. See :issue:`1555`.
* Update tested PyPy version from 7.2.0 on Windows to 7.3.1.
See :issue:`1569`.
+ Bugfixes
* Fix a spurious warning about watchers and resource leaks on
libuv on Windows. Reported by Stéphane Rainville. See
:issue:`1564`.
* Make monkey-patching properly remove select.epoll and
select.kqueue. Reported by Kirill Smelkov. See :issue:`1570`.
* Make it possible to monkey-patch :mod:`contextvars` before
Python 3.7 if a non-standard backport that uses the same name
as the standard library does is installed. Previously this
would raise an error. Reported by Simon Davy. See
:issue:`1572`.
* Fix destroying the libuv default loop and then using the
default loop again. See :issue:`1580`.
* libuv loops that have watched children can now exit.
Previously, the SIGCHLD watcher kept the loop alive even if
there were no longer any watched children. See :issue:`1581`.
+ Deprecations and Removals
* PyPy no longer uses the Python allocation functions for libuv
and libev allocations. See :issue:`1569`.
- Use the system libev by default
- Remove fix-tests.patch
- Remove use-libev-cffi.patch
- Greatly reduce the list of non functional tests
- Add fix-no-return-in-nonvoid-function.patch, applied for 15.1 and
below in order to not fail the build
- Add missing runtime dependencies:
python-zope.event and python-zope.interface

Fri Jan 3 11:51:00 CET 2020 - Matej Cepl <mcepl@suse.com>
- Use bundled libev library to overcome the current
incompatibility with libev > 4.25. gh#gevent/gevent#1501
-------------------------------------------------------------------
Thu Jan 2 14:09:44 CET 2020 - Matej Cepl <mcepl@suse.com>
- 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
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`.

* 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.

* The ``ref`` parameter to :func:`gevent.os.fork_and_watch` was being ignored.

:meth:`socket.socket.recvmsg` and :meth:`socket.socket.recvmsg_into`
on platforms where they are defined. Initial :pr:`773` by Jakub
