pyup-bot · 2024-09-21T12:16:39Z

This PR updates greenlet from 0.4.13 to 3.1.1.

Changelog

3.1.1

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

- Fix crashes on 32-bit PPC Linux. Note that there is no CI for this,
and support is best effort; there may be other issues lurking.
See `issue 422
&lt;https://github.com/python-greenlet/greenlet/issues/422&gt;`_.
- Remove unnecessary logging sometimes during interpreter shutdown.
See `issue 426 &lt;https://github.com/python-greenlet/greenlet/issues/426&gt;`_.
- Fix some crashes on 32-bit PPC MacOS. This is a very old platform,
and is only known to be tested on beta versions of an operating
system that was never released, using the GCC 14 only provided by
MacPorts; it may or may not work on the final MacOS X release that
supported 32-bit PowerPC. It has the known issue of leaking memory
when greenlets are used in multiple threads. Help debugging this
would be appreciated. See `PR 419
&lt;https://github.com/python-greenlet/greenlet/pull/419&gt;`_.

3.1.0

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

.. note::

 This will be the last release to support Python 3.7 and 3.8.

- Adds support for Python 3.13.

.. note::

greenlet will not work in no-gil (free threaded) builds of CPython.
Internally, greenlet heavily depends on the GIL.

- Greatly reduce the chances for crashes during interpreter shutdown.
See `issue 411
&lt;https://github.com/python-greenlet/greenlet/issues/411&gt;`_.

Platform Support
----------------

Support for the following platforms was contributed by the community.
Note that they are untested by this project&#x27;s continuous integration
services.

- Hitachi&#x27;s `SuperH CPU &lt;https://github.com/python-greenlet/greenlet/issues/166&gt;`_.
- `NetBSD on PowerPC.
&lt;https://github.com/python-greenlet/greenlet/pull/402&gt;`_
- RiscV 64 with `-fno-omit-frame-pointer
&lt;https://github.com/python-greenlet/greenlet/pull/404&gt;`_. Note that
there are `known test failures
&lt;https://github.com/python-greenlet/greenlet/issues/403&gt;`_, so this
platform may not work reliably at all.

3.0.3

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

- Python 3.12: Restore the full ability to walk the stack of a suspended
greenlet; previously only the innermost frame was exposed. See `issue 388
&lt;https://github.com/python-greenlet/greenlet/issues/388&gt;`_. Fix by
Joshua Oreman in `PR 393
&lt;https://github.com/python-greenlet/greenlet/pull/393/&gt;`_.

3.0.2

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

- Packaging: Add a minimal ``pyproject.toml`` to sdists.
- Packaging: Various updates to macOS wheels.
- Fix a test case on Arm32. Note that this is not a supported platform
(there is no CI for it) and support is best effort; there may be
other issues lurking. See `issue 385 &lt;https://github.com/python-greenlet/greenlet/issues/385&gt;`_

3.0.1

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

- Fix a potential crash on Python 3.8 at interpreter shutdown time.
This was a regression from earlier 3.0.x releases. Reported by Matt
Wozniski in `issue 376 &lt;https://github.com/python-greenlet/greenlet/issues/376&gt;`_.

3.0.0

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

- No changes from 3.0rc3 aside from the version number.

3.0.0rc3

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

- Fix an intermittent error during process termination on some
platforms (GCC/Linux/libstdc++).

3.0.0rc2

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

- Fix some potential bugs (assertion failures and memory leaks) in
previously-untested error handling code. In some cases, this means
that the process will execute a controlled ``abort()`` after severe
trouble when previously the process might have continued for some
time with a corrupt state. It is unlikely those errors occurred in
practice.
- Fix some assertion errors and potential bugs with re-entrant
switches.
- Fix a potential crash when certain compilers compile greenlet with
high levels of optimization. The symptom would be that switching to
a greenlet for the first time immediately crashes.
- Fix a potential crash when the callable object passed to the
greenlet constructor (or set as the ``greenlet.run`` attribute) has
a destructor attached to it that switches. Typically, triggering
this issue would require an unlikely subclass of
``greenlet.greenlet``.
- Python 3.11+: Fix rare switching errors that could occur when a
garbage collection was triggered during the middle of a switch, and
Python-level code in ``__del__`` or weakref callbacks switched to a
different greenlet and ultimately switched back to the original
greenlet. This often manifested as a ``SystemError``: &quot;switch
returned NULL without an exception set.&quot;

For context on the fixes, see `gevent issue 1985
&lt;https://github.com/gevent/gevent/issues/1985&gt;`_.

3.0.0rc1

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

- Windows wheels are linked statically to the C runtime in an effort
to prevent import errors on systems without the correct C runtime
installed. It&#x27;s not clear if this will make the situation better or
worse, so please share your experiences in `issue 346
&lt;https://github.com/python-greenlet/greenlet/issues/346&gt;`_.

Note that this only applies to the binary wheels found on PyPI.
Building greenlet from source defaults to the shared library. Set
the environment variable ``GREENLET_STATIC_RUNTIME=1`` at build time
to change that.
- Build binary wheels for Python 3.12 on macOS.
- Fix compiling greenlet on a debug build of CPython 3.12. There is
`one known issue
&lt;https://github.com/python-greenlet/greenlet/issues/368&gt;`_ that
leads to an interpreter crash on debug builds.
- Python 3.12: Fix walking the frame stack of suspended greenlets.
Previously accessing ``glet.gr_frame.f_back`` would crash due to
`changes in CPython&#x27;s undocumented internal frame handling &lt;https://github.com/python/cpython/commit/1e197e63e21f77b102ff2601a549dda4b6439455&gt;`_.

Platforms
---------
- Now, greenlet *may* compile and work on Windows ARM64 using
llvm-mingw, but this is untested and unsupported. See `PR
&lt;https://github.com/python-greenlet/greenlet/pull/224&gt;`_ by Adrian
Vladu.
- Now, greenlet *may* compile and work on LoongArch64 Linux systems,
but this is untested and unsupported. See `PR 257
&lt;https://github.com/python-greenlet/greenlet/pull/257/files&gt;`_ by merore.

Known Issues
------------

- There may be (very) subtle issues with tracing on Python 3.12, which
has redesigned the entire tracing infrastructure.

3.0.0a1

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

- Build binary wheels for S390x Linux. See `PR 358
&lt;https://github.com/python-greenlet/greenlet/pull/358&gt;`_ from Steven
Silvester.
- Fix a rare crash on shutdown seen in uWSGI deployments. See `issue
330 &lt;https://github.com/python-greenlet/greenlet/issues/330&gt;`_ and `PR 356
&lt;https://github.com/python-greenlet/greenlet/pull/356&gt;`_ from Andrew
Wason.
- Make the platform-specific low-level C/assembly snippets stop using
the ``register`` storage class. Newer versions of standards remove
this storage class, and it has been generally ignored by many
compilers for some time. See `PR 347
&lt;https://github.com/python-greenlet/greenlet/pull/347&gt;`_ from Khem
Raj.
- Add initial support for Python 3.12. See `issue
&lt;https://github.com/python-greenlet/greenlet/issues/323&gt;`_ and `PR
&lt;https://github.com/python-greenlet/greenlet/pull/327&gt;`_; thanks go
to (at least) Michael Droettboom, Andreas Motl, Thomas A Caswell,
raphaelauv, Hugo van Kemenade, Mark Shannon, and Petr Viktorin.
- Remove support for end-of-life Python versions, including Python
2.7, Python 3.5 and Python 3.6.
- Require a compiler that supports ``noinline`` directives. See
`issue 271
&lt;https://github.com/python-greenlet/greenlet/issues/266&gt;`_.
- Require a compiler that supports C++11.

2.0.2

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

- Fix calling ``greenlet.settrace()`` with the same tracer object that
was currently active. See `issue 332
&lt;https://github.com/python-greenlet/greenlet/issues/332&gt;`_.
- Various compilation and standards conformance fixes. See 335, 336,
300, 302, 334.

2.0.1

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

- Python 3.11: Fix a memory leak. See `issue 328
&lt;https://github.com/python-greenlet/greenlet/issues/328&gt;`_ and
`gevent issue 1924 &lt;https://github.com/gevent/gevent/issues/1924&gt;`_.

2.0.0.post0

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

- Add ``Programming Language :: Python :: 3.11`` to the PyPI
classifier metadata.

2.0.0

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

- Nothing changed yet.

2.0.0rc5

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

- Linux: Fix another group of rare crashes that could occur when shutting down an
interpreter running multiple threads. See `issue 325 &lt;https://github.com/python-greenlet/greenlet/issues/325&gt;`_.

2.0.0rc4

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

- Linux: Fix a rare crash that could occur when shutting down an
interpreter running multiple threads, when some of those threads are
in greenlets making calls to functions that release the GIL.

2.0.0rc3

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

- Python 2: Fix a crash that could occur when raising an old-style
instance object.

2.0.0rc2

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

- Workaround `a CPython 3.8 bug
&lt;https://github.com/python/cpython/issues/81308&gt;`_ that could cause
the interpreter to crash during an early phase of shutdown with the
message &quot;Fatal Python error: Python memory allocator called without
holding the GI.&quot; This only impacted CPython 3.8a3 through CPython
3.9a5; the fix is only applied to CPython 3.8 releases (please don&#x27;t
use an early alpha release of CPython 3.9).

2.0.0rc1

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

- Deal gracefully with greenlet switches that occur while deferred
deallocation of objects is happening using CPython&#x27;s &quot;trash can&quot;
mechanism. Previously, if a large nested container held items that
switched greenlets during delayed deallocation, and that second
greenlet also invoked the trash can, CPython&#x27;s internal state could
become corrupt. This was visible as an assertion error in debug
builds. Now, the relevant internal state is saved and restored
during greenlet switches. See also `gevent issue 1909
&lt;https://github.com/gevent/gevent/issues/1909&gt;`_.
- Rename the C API function ``PyGreenlet_GET_PARENT`` to
``PyGreenlet_GetParent`` for consistency. The old name remains
available as a deprecated alias.

2.0.0a2

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

- Fix a crash on older versions of the Windows C runtime when an
unhandled C++ exception was thrown inside a greenlet by another
native extension. This is a bug in that extension, and the
interpreter will still abort, but at least it does so deliberately.
Thanks to Kirill Smelkov. See `PR 286
&lt;https://github.com/python-greenlet/greenlet/pull/286&gt;`_.
- Musllinux wheels for aarch64 are now built, tested, and uploaded to
PyPI. Thanks to Alexander Piskun.
- This version of greenlet is known to compile and pass tests on
CPython 3.11.0a6. Earlier 3.11 releases will not work; later
releases may or may not work. See `PR 294
&lt;https://github.com/python-greenlet/greenlet/pull/294&gt;`_. Special
thanks to Victor Stinner, Brandt Bucher and the CPython developers.

2.0.0a1

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

Platforms
---------

- Add experimental, untested support for 64-bit Windows on ARM using
MSVC. See `PR 271 &lt;https://github.com/python-greenlet/greenlet/pull/271&gt;`_.

- Drop support for very old versions of GCC and MSVC.

- Compilation now requires a compiler that either supports C++11 or
has some other intrinsic way to create thread local variables; for
older GCC, clang and SunStudio we use ``__thread``, while for older
MSVC we use ``__declspec(thread)``.

- Wheels compatible with the musllinux specification are built,
tested, and uploaded to PyPI for x86_64. (This was retroactively
done for version 1.1.2 as well.)

- This version of greenlet is known to compile and pass tests on
CPython 3.11.0a4. Earlier or later 3.11 releases may or may not
work. See `PR 280
&lt;https://github.com/python-greenlet/greenlet/pull/280&gt;`_. Special
thanks to Brandt Bucher and the CPython developers.

Fixes
~~~~~

- Fix several leaks that could occur when using greenlets from
multiple threads. For example, it is no longer necessary to call
``getcurrent()`` before exiting a thread to allow its main greenlet
to be cleaned up. See `issue 252 &lt;https://github.com/python-greenlet/greenlet/issues/251&gt;`_.

- Fix the C API ``PyGreenlet_Throw`` to perform the same error
checking that the Python API ``greenlet.throw()`` does. Previously,
it did no error checking.

- Fix C++ exception handling on 32-bit Windows. This might have
ramifications if you embed Python in your application and also use
SEH on 32-bit windows, or if you embed Python in a C++ application.
Please contact the maintainers if you have problems in this area.

In general, C++ exception handling is expected to be better on most
platforms. This work is ongoing.

Changes
~~~~~~~

- The repr of some greenlets has changed. In particular, if the
greenlet object was running in a thread that has exited, the repr
now indicates that. *NOTE:* The repr of a greenlet is not part of
the API and should not be relied upon by production code. It is
likely to differ in other implementations such as PyPy.

- Main greenlets from threads that have exited are now marked as dead.

1.1.3.post0

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

- Add musllinux (Alpine) binary wheels.

.. important:: This preliminary support for Python 3.11 leaks memory.
            Please upgrade to greenlet 2 if you&#x27;re using Python 3.11.

1.1.3

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

- Add support for Python 3.11. Please note that Windows binary wheels
are not available at this time.

.. important:: This preliminary support for Python 3.11 leaks memory.
            Please upgrade to greenlet 2 if you&#x27;re using Python 3.11.

1.1.2

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

- Fix a potential crash due to a reference counting error when Python
subclasses of ``greenlet.greenlet`` were deallocated. The crash
became more common on Python 3.10; on earlier versions, silent
memory corruption could result. See `issue 245
&lt;https://github.com/python-greenlet/greenlet/issues/245&gt;`_. Patch by
fygao-wish.
- Fix a leak of a list object when the last reference to a greenlet
was deleted from some other thread than the one to which it
belonged. For this to work correctly, you must call a greenlet API
like ``getcurrent()`` before the thread owning the greenlet exits:
this is a long-standing limitation that can also lead to the leak of
a thread&#x27;s main greenlet if not called; we hope to lift this
limitation. Note that in some cases this may also fix leaks of
greenlet objects themselves. See `issue 251
&lt;https://github.com/python-greenlet/greenlet/issues/251&gt;`_.
- Python 3.10: Tracing or profiling into a spawned greenlet didn&#x27;t
work as expected. See `issue 256
&lt;https://github.com/python-greenlet/greenlet/issues/256&gt;`_, reported
by Joe Rickerby.

1.1.1

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

- Provide Windows binary wheels for Python 3.10 (64-bit only).

- Update Python 3.10 wheels to be built against 3.10rc1, where
applicable.

1.1.0

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

- Add support for Python 3.10. Pre-built binary wheels for 3.10 are
not currently available for all platforms. The greenlet ABI is
different on Python 3.10 from all previous versions, but as 3.10 was
never supported before, and the ABI has not changed on other Python
versions, this is not considered a reason to change greenlet&#x27;s major
version.

1.0.0

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

- Fix %s and %r formatting of a greenlet on Python 2. Previously it
would result in a Unicode string instead of a native string. See
`issue 218
&lt;https://github.com/python-greenlet/greenlet/issues/218&gt;`_.

- Move continuous integration from Travis CI to Github Actions.

1.0a1

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

- Add the ability to set a greenlet&#x27;s PEP 567 contextvars context
directly, by assigning to the greenlet&#x27;s ``gr_context`` attribute.
This restores support for some patterns of using greenlets atop an
async environment that became more challenging in 0.4.17. Thanks to
Joshua Oreman, Mike bayer, and Fantix King, among others. See `PR
198 &lt;https://github.com/python-greenlet/greenlet/pull/198/&gt;`_.

- The repr of greenlet objects now includes extra information about
its state. This is purely informative and the details are subject to
change. See `issue 215 &lt;https://github.com/python-greenlet/greenlet/issues/215&gt;`_.

- The ``greenlet`` module is now a package. There are no API changes,
so all existing imports, including from C code, should continue to
work.

- (C API) The undocumented ``GREENLET_VERSION`` macro that defined a string
giving the greenlet version is now deprecated and will not be updated.

- (Documentation) Publish the change log to https://greenlet.readthedocs.io

Supported Platforms
-------------------

- Drop support for Python 2.4, 2.5, 2.6, 3.0, 3.1, 3.2 and 3.4.
The project metadata now includes the ``python_requires`` data to
help installation tools understand supported versions.
- Add partial support for AIX ppc64 and IBM i. Thanks to Jesse
Gorzinski and Kevin Adler. See `PR 197
&lt;https://github.com/python-greenlet/greenlet/pull/197&gt;`_.

Packaging Changes
-----------------

- Require setuptools to build from source.
- Stop asking setuptools to build both .tar.gz and .zip
sdists. PyPI has standardized on .tar.gz for all platforms.
- Stop using a custom distutils command to build
extensions. distutils is deprecated.
- Remove the ability to use the deprecated command
``python setup.py test``. Run greenlet tests with your favorite
unittest-compatible test runner, e.g., ``python -m unittest discover
greenlet.tests``. See `issue 185 &lt;https://github.com/python-greenlet/greenlet/issues/185&gt;`_.
- The directory layout and resulting sdists have changed.
See `issue 184
&lt;https://github.com/python-greenlet/greenlet/issues/184&gt;`_.
- greenlet is now always built with support for tracing and garbage
collection, and, on Python 3.7 and above, support for context
variables. The internal and undocumented C preprocessor macros that
could be used to alter that at compile time have been removed (no
combination other than the defaults was ever tested). This helps
define a stable ABI.
