At Python exit, if a callback registered with atexit.register()
fails, its exception is now logged. Previously, only some exceptions
were logged, and the last exception was always silently ignored.
Add _PyAtExit_Call() function and remove
PyInterpreterState.atexit_func member. call_py_exitfuncs() now calls
directly _PyAtExit_Call().
The atexit module must now always be built as a built-in module.
patch, patch.object and create_autospec silently ignore misspelled
arguments such as autospect, auto_spec and set_spec. This can lead
to tests failing to check what they are supposed to check.
This change adds a check causing a RuntimeError if the above
functions get any of the above misspellings as arguments. It also
adds a new argument, "unsafe", which can be set to True to disable
this check.
Also add "!r" to format specifiers in added error messages.
Add positional only args support to lib2to3 pgen2.
This adds 3.8's PEP-570 support to lib2to3's pgen2. lib2to3, while
being deprecated is still used by things to parse all versions of Python
code today. We need it to support parsing modern 3.8 and 3.9 constructs.
Also add tests for complex *expr and **expr's.
This is invalid in C99 and later and is an error with some compilers
(e.g. clang in Xcode 12), and can thus cause configure checks to
produce incorrect results.
This allows easier Enum construction in unusual cases, such as including dynamic member definitions into a class definition:
# created dynamically
foo_defines = {'FOO_CAT': 'aloof', 'BAR_DOG': 'friendly', 'FOO_HORSE': 'big'}
class Foo(Enum):
vars().update({
k: v
for k, v in foo_defines.items()
if k.startswith('FOO_')
})
def upper(self):
# example method
return self.value.upper()
The default for auto() is to return an integer, which doesn't work for `StrEnum`. The new `_generate_next_value_` for `StrEnum` returns the member name, lower cased.
This is a follow-up to
4662fa9bfe.
That original commit expanded guards against misspelling assertions on
mocks. This follow-up updates the documentation and improves the error
message by pointing out the potential cause and solution.

Export the Py_FrozenMain() function: fix a Python 3.9.0 regression.
Python 3.9 uses -fvisibility=hidden and the function was not exported
explicitly and so not exported.
Add also Py_FrozenMain to the stable ABI on Windows.
When creating an Enum, type.__new__ calls __init_subclass__, but at that point the members have not been added.
This patch suppresses the initial call, then manually calls the ancestor __init_subclass__ before returning the new Enum class.
pymain_run_file() no longer encodes the filename: pass the filename
as an object to the new _PyRun_AnyFileObject() function.
Add new private functions:
* _PyRun_AnyFileObject()
* _PyRun_InteractiveLoopObject()
* _Py_FdIsInteractive()
- Copy existing xxlimited to xxlimited53 (named for the limited API version it uses)
- Build both modules, both in debug and release
- Test both modules
Fix encoding name when running a ".pyc" file on Windows:
PyRun_SimpleFileExFlags() now uses the correct encoding to decode the
filename.
* Add pyrun_file() subfunction.
* Add pyrun_simple_file() subfunction.
* PyRun_SimpleFileExFlags() now calls _Py_fopen_obj() rather than
_Py_fopen().
The solution in gh#python/cpython#13236 is too strict because it
effectively requires the use of Sphinx >= 2.0. It is not too difficult to
make the same solution more robust so it works with all normal versions
of Sphinx.
Remove obsolete workaround that prevented running files with
shortcuts when using new universal2 installers built on macOS 11.
Ignore buggy 2nd run_module_event call.
