Restore behavior from 3.9 and earlier when sending non-None to newly started
|
|
generator. In 3.9 this did not affect the state of the generator. In 3.10.0
|
|
and 3.10.1 ``gen_func().send(0)`` is equivalent to
|
|
``gen_func().throw(TypeError(...)`` which exhausts the generator. In 3.10.2
|
|
onward, the behavior has been reverted to that of 3.9.

The three values of ``exc_info`` are now always consistent with each other.
|
|
In particular, the ``type`` and ``traceback`` fields are now derived from
|
|
the exception instance. This impacts the return values of
|
|
:func:`sys.exc_info` and :c:func:`PyErr_GetExcInfo()` if the exception
|
|
instance is modified while the exception is handled, as well as
|
|
:c:func:`PyErr_SetExcInfo()`, which now ignores the ``type`` and
|
|
``traceback`` arguments provided to it.

Fix Python Launcher's ability to distinguish between versions 3.1 and 3.10

when either one is explicitly requested. Previously, 3.1 would be used if

3.10 was requested but not installed, and 3.10 would be used if 3.1 was

requested but 3.10 was installed.
