* bpo-33671 / shutil.copyfile: use memoryview() with dynamic size on Windows ↵Giampaolo Rodola2018-06-191-2/+2
| | | | | | | | | | (#7681) bpo-33671 * use memoryview() with size == file size on Windows, see https://github.com/python/cpython/pull/7160#discussion_r195405230 * release intermediate (sliced) memoryview immediately * replace "OSX" occurrences with "macOS" * add some unittests for copyfileobj()
* bpo-33671: efficient zero-copy for shutil.copy* functions (Linux, OSX and ↵Giampaolo Rodola2018-06-121-1/+39

* bpo-30600: Fix error messages (condition order in Argument Clinic) (#2051)Sylvain2017-06-101-106/+106
| | | | | | | | The function '_PyArg_ParseStack()' and '_PyArg_UnpackStack' were failing (with error "XXX() takes Y argument (Z given)") before the function '_PyArg_NoStackKeywords()' was called. Thus, the latter did not raise its more meaningful error : "XXX() takes no keyword arguments".
* bpo-16500: Don't use string constants for os.register_at_fork() behavior (#1834)Gregory P. Smith2017-05-291-17/+21
