IDLE

• bpo-31493 [https://bugs.python.org/issue?@action=redirect&bpo=31493]: IDLE code context — fix code update and font update timers. Canceling timers prevents a warning message when test_idle completes.

• bpo-31488 [https://bugs.python.org/issue?@action=redirect&bpo=31488]: IDLE - Update non-key options in former extension classes. When applying configdialog changes, call .reload for each feature class. Change ParenMatch so updated options affect existing instances attached to existing editor windows.

• bpo-31477 [https://bugs.python.org/issue?@action=redirect&bpo=31477]: IDLE - Improve rstrip entry in doc. Strip trailing whitespace strips more than blank spaces. Multiline string literals are not skipped.

• bpo-31480 [https://bugs.python.org/issue?@action=redirect&bpo=31480]: IDLE - make tests pass with zzdummy extension disabled by default.

• bpo-31421 [https://bugs.python.org/issue?@action=redirect&bpo=31421]: Document how IDLE runs tkinter programs. IDLE calls tcl/tk update in the background in order to make live interaction and experimentation with tkinter applications much easier.

• bpo-31414 [https://bugs.python.org/issue?@action=redirect&bpo=31414]: IDLE — fix tk entry box tests by deleting first. Adding to an int entry is not the same as deleting and inserting because int('') will fail.

• bpo-31051 [https://bugs.python.org/issue?@action=redirect&bpo=31051]: Rearrange IDLE configdialog GenPage into Window, Editor, and Help sections.

• bpo-30617 [https://bugs.python.org/issue?@action=redirect&bpo=30617]: IDLE - Add docstrings and tests for outwin subclass of editor. Move some data and functions from the class to module level. Patch by Cheryl Sabella.

• bpo-31287 [https://bugs.python.org/issue?@action=redirect&bpo=31287]: IDLE - Do not modify tkinter.message in test_configdialog.

• bpo-27099 [https://bugs.python.org/issue?@action=redirect&bpo=27099]: Convert IDLE's builtin 'extensions' to regular features. About 10 IDLE features were implemented as supposedly optional extensions. Their different behavior could be confusing or worse for users and not good for maintenance. Hence the conversion. The main difference for users is that user configurable key bindings for builtin features are now handled uniformly. Now, editing a binding in a keyset only affects its value in the keyset. All bindings are defined together in the system-specific default keysets in config-extensions.def. All custom keysets are saved as a whole in config-extension.cfg. All take effect as soon as one clicks Apply or Ok. The affected events are '<>', '<>', '<>', '<>', '<>', '<>', '<>', and '<>'. Any (global) customizations made before 3.6.3 will not affect their keyset-specific customization after 3.6.3. and vice versa. Initial patch by Charles Wohlganger.

• bpo-31206 [https://bugs.python.org/issue?@action=redirect&bpo=31206]: IDLE: Factor HighPage(Frame) class from ConfigDialog. Patch by Cheryl Sabella.

• bpo-19903 [https://bugs.python.org/issue?@action=redirect&bpo=19903]: IDLE: Calltips use inspect.signature instead of inspect.getfullargspec. This improves calltips for builtins converted to use Argument Clinic. Patch by Louie Lu.

• bpo-31083 [https://bugs.python.org/issue?@action=redirect&bpo=31083]: IDLE - Add an outline of a TabPage class in configdialog. Update existing classes to match outline. Initial patch by Cheryl Sabella.

• bpo-30853 [https://bugs.python.org/issue?@action=redirect&bpo=30853]: IDLE — Factor a VarTrace class out of ConfigDialog. Instance tracers manages pairs consisting of a tk variable and a callback function. When tracing is turned on, setting the variable calls the function. Test coverage for the new class is 100%.

• bpo-31003 [https://bugs.python.org/issue?@action=redirect&bpo=31003]: IDLE: Add more tests for General tab.

• bpo-30993 [https://bugs.python.org/issue?@action=redirect&bpo=30993]: IDLE - Improve configdialog font page and tests. In configdialog: Document causal pathways in create_font_tab docstring. Simplify some attribute names. Move set_samples calls to var_changed_font (idea from Cheryl Sabella). Move related functions to positions after the create widgets function. In test_configdialog: Fix test_font_set so not order dependent. Fix renamed test_indent_scale so it tests the widget. Adjust tests for movement of set_samples call. Add tests for load functions. Put all font tests in one class and tab indent tests in another. Except for two lines, these tests completely cover the related functions.

• bpo-30981 [https://bugs.python.org/issue?@action=redirect&bpo=30981]: IDLE — Add more configdialog font page tests.

• bpo-28523 [https://bugs.python.org/issue?@action=redirect&bpo=28523]: IDLE: replace 'colour' with 'color' in configdialog.

• bpo-30913 [https://bugs.python.org/issue?@action=redirect&bpo=30913]: IDLE: Document ConfigDialog tk Vars, methods, and widgets in docstrings This will facilitate improving the dialog and splitting up the class. Original patch by Cheryl Sabella.

• bpo-30899 [https://bugs.python.org/issue?@action=redirect&bpo=30899]: IDLE: Add tests for ConfigParser subclasses in config. Patch by Louie Lu.

In config, put dump test code in a function; run it and unittest in 'if name == 'main'. Add class config.ConfigChanges based on changes_class_v4.py on bpo issue. Add class test_config.ChangesTest, partly using configdialog_tests_v1.py. Revise configdialog to use ConfigChanges; see tracker msg297804. Revise test_configdialog to match configdialog changes. Remove configdialog functions unused or moved to ConfigChanges. Cheryl Sabella contributed parts of the patch.

• bpo-30723 [https://bugs.python.org/issue?@action=redirect&bpo=30723]: IDLE: Make several improvements to parenmatch. Add 'parens' style to highlight both opener and closer. Make 'default' style, which is not default, a synonym for 'opener'. Make time-delay work the same with all styles. Add help for config dialog extensions tab, including help for parenmatch. Add new tests. Original patch by Charles Wohlganger.

• bpo-30674 [https://bugs.python.org/issue?@action=redirect&bpo=30674]: IDLE: add docstrings to grep module. Patch by Cheryl Sabella

工具/示例

• bpo-30983 [https://bugs.python.org/issue?@action=redirect&bpo=30983]: gdb integration commands (py-bt, etc.) work on optimized shared builds now, too. PEP 523 [https://peps.python.org/pep-0523/] introduced PyEvalEvalFrameDefault which inlines PyEval_EvalFrameEx on non-debug shared builds. This broke the ability to use py-bt, py-up, and a few other Python-specific gdb integrations. The problem is fixed by only looking for PyEvalEvalFrameDefault frames in python-gdb.py. Original patch by Bruno "Polaco" Penteado.

核心与内置函数

• bpo-29723 [https://bugs.python.org/issue?@action=redirect&bpo=29723]: The sys.path[0] initialization change for bpo-29139 [https://bugs.python.org/issue?@action=redirect&bpo=29139] caused a regression by revealing an inconsistency in how sys.path is initialized when executing __main__ from a zipfile, directory, or other import location. The interpreter now consistently avoids ever adding the import location's parent directory to sys.path, and ensures no other sys.path entries are inadvertently modified when inserting the import location named on the command line.
