``_abc`` module is added. It is a speedup module with C implementations for
|
|
various functions and methods in ``abc``. Creating an ABC subclass and
|
|
calling ``isinstance`` or ``issubclass`` with an ABC subclass are up to 1.5x
|
|
faster. In addition, this makes Python start-up up to 10% faster.
|
|
Note that the new implementation hides internal registry and caches,
|
|
previously accessible via private attributes ``_abc_registry``,
|
|
``_abc_cache``, and ``_abc_negative_cache``. There are three debugging
|
|
helper methods that can be used instead ``_dump_registry``,
|
|
``_abc_registry_clear``, and ``_abc_caches_clear``.

idea for IDLE's system and location-independent files.

Add "encoding=utf-8" to open() in IDLE's test_help_about. GUI test
|
|
test_file_buttons() only looks at initial ascii-only lines, but failed on
|
|
systems where open() defaults to 'ascii' because readline() internally reads
|
|
and decodes far enough ahead to encounter a non-ascii character in
|
|
CREDITS.txt.
