* [3.12] gh-125355: Rewrite parse_intermixed_args() in argparse (GH-125356) ↵Serhiy Storchaka2024-10-221-65/+34
| | | | | | | | | | | | | | (GH-125839) * The parser no longer changes temporarily during parsing. * Default values are not processed twice. * Required mutually exclusive groups containing positional arguments are now supported. * The missing arguments report now includes the names of all required optional and positional arguments. * Unknown options can be intermixed with positional arguments in parse_known_intermixed_args(). (cherry picked from commit 759a54d28ffe7eac8c23917f5d3dfad8309856be)

| | | | | | | | | (GH-125273) (GH-125360) This was a regression introduced in gh-58573. It was only tested for the case when the ambiguous option is the last argument in the command line.

| | | | | | | | This removes the unused `name` variable in the block where `ArgumentTypeError` is handled. `ArgumentTypeError` errors are handled by showing just the string of the exception; unlike `ValueError`, the name (`__name__`) of the function is not included in the error message.

Fixes https://bugs.python.org/issue38956 as this code will detect whether '%(default)s' has already been specified in the help string.

This is consistent with the (default) behavior when the same option string is added twice to an ArgumentParser.
