* gh-118314: Fix padding edge case in binascii.a2b_base64 strict mode (GH-118320)Youfu Zhang2024-05-073-0/+23
| | | | | | | Fix an edge case in `binascii.a2b_base64` strict mode, where excessive padding was not detected when no padding is necessary. Co-authored-by: Terry Jan Reedy <tjreedy@udel.edu> Co-authored-by: Pieter Eendebak <pieter.eendebak@gmail.com>

* gh-62090: Simplify argparse usage formatting (GH-105039)Ali Hamdan2024-05-073-72/+164
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rationale ========= argparse performs a complex formatting of the usage for argument grouping and for line wrapping to fit the terminal width. This formatting has been a constant source of bugs for at least 10 years (see linked issues below) where defensive assertion errors are triggered or brackets and paranthesis are not properly handeled. Problem ======= The current implementation of argparse usage formatting relies on regular expressions to group arguments usage only to separate them again later with another set of regular expressions. This is a complex and error prone approach that caused all the issues linked below. Special casing certain argument formats has not solved the problem. The following are some of the most common issues: - empty `metavar` - mutually exclusive groups with `SUPPRESS`ed arguments - metavars with whitespace - metavars with brackets or paranthesis Solution ======== The following two comments summarize the solution: - https://github.com/python/cpython/issues/82091#issuecomment-1093832187 - https://github.com/python/cpython/issues/77048#issuecomment-1093776995 Mainly, the solution is to rewrite the usage formatting to avoid the group-then-separate approach. Instead, the usage parts are kept separate and only joined together at the end. This allows for a much simpler implementation that is easier to understand and maintain. It avoids the regular expressions approach and fixes the corresponding issues. This closes the following GitHub issues: - #62090 - #62549 - #77048 - #82091 - #89743 - #96310 - #98666 These PRs become obsolete: - #15372 - #96311

* gh-117953: Always Run Extension Init Func in Main Interpreter First (gh-118157)Eric Snow2024-05-074-69/+216
| | | This change makes sure all extension/builtin modules have their init function run first by the main interpreter before proceeding with import in the original interpreter (main or otherwise). This means when the import of a single-phase init module fails in an isolated subinterpreter, it won't tie any global state/callbacks to the subinterpreter.
* gh-117953: Imply Single-phase Init if the Init Function Fails (gh-118684)Eric Snow2024-05-071-0/+7
| | | This ensures the kind is always either _Py_ext_module_kind_SINGLEPHASE or _Py_ext_module_kind_MULTIPHASE.
* gh-116322: Enable the GIL while loading C extension modules (#118560)Brett Simmers2024-05-079-32/+352
| | | | | | | | | | Add the ability to enable/disable the GIL at runtime, and use that in the C module loading code. We can't know before running a module init function if it supports free-threading, so the GIL is temporarily enabled before doing so. If the module declares support for running without the GIL, the GIL is later disabled. Otherwise, the GIL is permanently enabled, and will never be disabled again for the life of the current interpreter.

| | | | | | The previous change made the `glob` module slower to import, because it imported `pathlib._glob` and hence the rest of `pathlib`. Reverts a40f557d7b7a355a55bb90c068e3e9202fd9c8f2.

* gh-117486: Improve behavior for user-defined AST subclasses (#118212)Jelle Zijlstra2024-05-066-33/+94
| | | | | | | | Now, such classes will no longer require changes in Python 3.13 in the normal case. The test suite for robotframework passes with no DeprecationWarnings under this PR. I also added a new DeprecationWarning for the case where `_field_types` exists but is incomplete, since that seems likely to indicate a user mistake.

* gh-71592: Add ability to trace Tcl commands executed by Tkinter (GH-118291)Serhiy Storchaka2024-05-063-6/+190
| | | | | | | | | | | | This is an experimental feature, for internal use. Setting tkinter._debug = True before creating the root window enables printing every executed Tcl command (or a Tcl command equivalent to the used Tcl C API). This will help to convert a Tkinter example into Tcl script to check whether the issue is caused by Tkinter or exists in the underlying Tcl/Tk library.
