[issue19965] Non-atomic generation of Include/Python-ast.h and Python/Python-ast.c

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I think os.replace() should be used instead os.rename(). Or pair os.unlink()/os.rename().

And perhaps for decreasing chance of race between creating .c and .h files, both renames should be done after writing both files.
