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-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-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.

Added functions PySlice_Unpack() and PySlice_AdjustIndices().

• bpo-29083 [https://bugs.python.org/issue?@action=redirect&bpo=29083]: Fixed the declaration of some public API functions. PyArg_VaParse() and PyArg_VaParseTupleAndKeywords() were not available in limited API. PyArg_ValidateKeywordArguments(), PyArg_UnpackTuple() and Py_BuildValue() were not available in limited API of version < 3.3 when PY_SSIZE_T_CLEAN is defined.

IDLE

• bpo-32984 [https://bugs.python.org/issue?@action=redirect&bpo=32984]: Set __file__ while running a startup file. Like Python, IDLE optionally runs one startup file in the Shell window before presenting the first interactive input prompt. For IDLE, -s runs a file named in environmental variable IDLESTARTUP or PYTHONSTARTUP; -r file runs file. Python sets __file__ to the startup file name before running the file and unsets it before the first prompt. IDLE now does the same when run normally, without the -n option.

• bpo-32207 [https://bugs.python.org/issue?@action=redirect&bpo=32207]: Improve tk event exception tracebacks in IDLE. When tk event handling is driven by IDLE's run loop, a confusing and distracting queue.EMPTY traceback context is no longer added to tk event exception tracebacks. The traceback is now the same as when event handling is driven by user code. Patch based on a suggestion by Serhiy Storchaka.

• bpo-31858 [https://bugs.python.org/issue?@action=redirect&bpo=31858]: IDLE — Restrict shell prompt manipulation to the shell. Editor and output windows only see an empty last prompt line.

• bpo-13802 [https://bugs.python.org/issue?@action=redirect&bpo=13802]: Use non-Latin characters in the IDLE's Font settings sample. Even if one selects a font that defines a limited subset of the unicode Basic Multilingual Plane, tcl/tk will use other fonts that define a character. The expanded example give users of non-Latin characters a better idea of what they might see in IDLE's shell and editors. To make room for the expanded sample, frames on the Font tab are rearranged. The Font/Tabs help explains a bit about the additions.

• bpo-31460 [https://bugs.python.org/issue?@action=redirect&bpo=31460]: Simplify the API of IDLE's Module Browser. Passing a widget instead of an flist with a root widget opens the option of creating a browser frame that is only part of a window. Passing a full file name instead of pieces assumed to come from a .py file opens the possibility of browsing python files that do not end in .py.

The original module-level class and method browser became a module browser, with the addition of module-level functions, years ago. Nested classes and functions were added yesterday. For back-compatibility, the virtual event <>, which appears on the Keys tab of the Settings dialog, is not changed. Patch by Cheryl Sabella.

• bpo-31500 [https://bugs.python.org/issue?@action=redirect&bpo=31500]: Default fonts now are scaled on HiDPI displays.

• bpo-1612262 [https://bugs.python.org/issue?@action=redirect&bpo=1612262]: IDLE module browser now shows nested classes and functions. Original patches for code and tests by Guilherme Polo and Cheryl Sabella, respectively.

• bpo-30807 [https://bugs.python.org/issue?@action=redirect&bpo=30807]: signal.setitimer() may disable the timer when passed a tiny value. Tiny values (such as 1e-6) are valid non-zero values for setitimer(), which is specified as taking microsecond-resolution intervals. However, on some platform, our conversion routine could convert 1e-6 into a zero interval, therefore disabling the timer instead of (re-)scheduling it.

• bpo-30441 [https://bugs.python.org/issue?@action=redirect&bpo=30441]: Fix bug when modifying os.environ while iterating over it

• bpo-30532 [https://bugs.python.org/issue?@action=redirect&bpo=30532]: Fix email header value parser dropping folding white space in certain cases.

• bpo-30879 [https://bugs.python.org/issue?@action=redirect&bpo=30879]: os.listdir() and os.scandir() now emit bytes names when called with bytes-like argument.

• bpo-30746 [https://bugs.python.org/issue?@action=redirect&bpo=30746]: Prohibited the '=' character in environment variable names in os.putenv() and os.spawn*().

• bpo-29755 [https://bugs.python.org/issue?@action=redirect&bpo=29755]: Fixed the lgettext() family of functions in the gettext module. They now always return bytes.

• bpo-30715 [https://bugs.python.org/issue?@action=redirect&bpo=30715]: Address ALPN callback changes for OpenSSL 1.1.0f. The latest version behaves like OpenSSL 1.0.2 and no longer aborts handshake.

• bpo-30822 [https://bugs.python.org/issue?@action=redirect&bpo=30822]: regrtest: Exclude tzdata from regrtest —all. When running the test suite using —use=all / -u all, exclude tzdata since it makes test_datetime too slow (15-20 min on some buildbots) which then times out on some buildbots. Fix also regrtest command line parser to allow passing -u extralargefile to run test_zipfile64.
