Improve multi-threaded performance by dropping the GIL in the fast path
of bytes.join. To avoid increasing overhead for small joins, it is only
done if the output size exceeds a threshold.
As Windows 7 is not supported by Python 3.9, we just replace the dynamic load with a static import. Backports will have a different fix to ensure they continue to behave the same.
In bpo-36264 os.path.expanduser was changed to ignore HOME on Windows.
Path.expanduser/home still honored HOME despite being documented as behaving the same
as os.path.expanduser. This makes them also ignore HOME so that both implementations
behave the same way again.
* Change the source for the SAT data to a primary source.
* Fix typo in the standard deviation
* Clarify that the binomial probabalities are just for the Python room.
Whether or not overlap regions for self-intersecting polygons
or multiple shapes are filled depends on the operating system graphics,
typeof overlap, and number of overlaps.
intern_strings() now raises a SystemError, rather than calling
Py_FatalError().
intern_string_constants() now reports exceptions to the caller,
rather than ignoring silently exceptions.
Expose dialog buttons to test code and complete their test coverage.

If the export count is negative, _memory_release() now raises a
SystemError and returns -1, rather than calling Py_FatalError()
which aborts the process.
If PyModule_Create2() is called when the Python import machinery is
not initialized, it now raises a SystemError and returns NULL,
instead of calling Py_FatalError() which aborts the process.
The caller must be prepared to handle NULL anyway.
- The gc.collect is needed for other implementations, such as pypy
- Using context managers over multiple lines will only catch the warning from the first line in the context!
- remove a skip for a test that no longer fails on pypy
* Add DICT_UPDATE and DICT_MERGE bytecodes. Use them for ** unpacking.
* Remove BUILD_MAP_UNPACK and BUILD_MAP_UNPACK_WITH_CALL, as they are now unused.
* Update magic number for ** unpacking opcodes.
* Update dis.rst to incorporate new bytecodes.
* Add blurb entry.
collect() should not get an exception, but it does, logging the
exception is enough. Override sys.unraisablehook to decide how to
handle unraisable exceptions.
Py_FatalError() should be avoided whenever possible.
The os.putenv() and os.unsetenv() functions are now always available.
On non-Windows platforms, Python now requires setenv() and unsetenv()
functions to build.
Remove putenv_dict from posixmodule.c: it's not longer needed.
Some portions of the pickle documentation hadn't been updated for the pickle protocol changes in Python 3.8 (new protocol 5, default protocol 4). This PR fixes those docs.
