* gh-111903: Add `@critical_section` directive to Argument Clinic. (#111904)Sam Gross2023-11-145-8/+117
| | | | | | | | | The `@critical_section` directive instructs Argument Clinic to generate calls to `Py_BEGIN_CRITICAL_SECTION()` and `Py_END_CRITICAL_SECTION()` around the bound function. In `--disable-gil` builds, these calls will lock and unlock the `self` object. They are no-ops in the default build. This is used in one place (`_io._Buffered.close`) as a demonstration. Subsequent PRs will use it more widely in the `_io.Buffered` bindings.

* GH-110417: Fix `glob` docs ordering (#110418)Barney Gale2023-11-131-34/+35
| | | | | | | Fix incorrect placement of `translate()` docs from cf67ebf. Move "see also: pathlib" admonition to the bottom of the page, alongside one for fnmatch. This helps the module introduction flow more naturally into the function descriptions. Add an "Examples" subheading just before the examples. This makes it more obvious that examples aren't specifically related to the preceding documentation of `escape()` and `translate()`.
* GH-72904: Add `glob.translate()` function (#106703)Barney Gale2023-11-137-106/+229
| | | | | | | | | | | Add `glob.translate()` function that converts a pathname with shell wildcards to a regular expression. The regular expression is used by pathlib to implement `match()` and `glob()`. This function differs from `fnmatch.translate()` in that wildcards do not match path separators by default, and that a `*` pattern segment matches precisely one path segment. When *recursive* is set to true, `**` pattern segments match any number of path segments, and `**` cannot appear outside its own segment. In pathlib, this change speeds up directory walking (because `_make_child_relpath()` does less work), makes path objects smaller (they don't need a `_lines` slot), and removes the need for some gnarly code.

* gh-111138: Add PyList_Extend() and PyList_Clear() functions (#111862)Victor Stinner2023-11-138-127/+303
| | | | | | * Split list_extend() into two sub-functions: list_extend_fast() and list_extend_iter(). * list_inplace_concat() no longer has to call Py_DECREF() on the list_extend() result, since list_extend() now returns an int.

* gh-111777: Fix assertion errors on incorrectly still-tracked GC object ↵T. Wouters2023-11-121-1/+3
| | | | | | | | | | destruction (#111778) In PyObject_GC_Del, in Py_DEBUG mode, when warning about GC objects that were not properly untracked before starting destruction, take care to untrack the object _before_ warning, to avoid triggering a GC run and causing the problem the code tries to warn about. Also make sure to save and restore any pending exceptions, which the warning would otherwise clobber or trigger an assertion error on.
* Fix undefined behaviour in datetime.time.fromisoformat() (#111982)T. Wouters2023-11-111-1/+1
| | | Fix undefined behaviour in datetime.time.fromisoformat() when parsing a string without a timezone. 'tzoffset' is not assigned to by parse_isoformat_time if it returns 0, but time_fromisoformat then passes tzoffset to another function, which is undefined behaviour (even if the function in question does not use the value).
* gh-90890: New methods to access mailbox.Maildir message info and flags (#103905)Stephen Gildea2023-11-115-1/+247
| | | | | | | | | | | | | | | New methods to access mailbox.Maildir message info and flags: get_info, set_info, get_flags, set_flags, add_flag, remove_flag. These methods speed up accessing a message's info and/or flags and are useful when it is not necessary to access the message's contents, as when iterating over a Maildir to find messages with specific flags. --------- * Add more str type checking * modernize to f-strings instead of % Co-authored-by: Gregory P.

The traditional trace is left in place for use with sequential in-process test runs but now raises a warning that those numbers are not precise. `-T -j` requires `--with-pydebug` as it relies on `-Xpresite=`.

| | | | | | | | This adds a macro `Py_CAN_START_THREADS` that corresponds to the Python function `test.support.threading_helper.can_start_thread()`.

* gh-111881: Import _sha2 lazily in random (#111889)Victor Stinner2023-11-091-11/+15
| | | | | | | The random module now imports the _sha2 module lazily in the Random.seed() method for str, bytes and bytearray seeds. It also imports lazily the warnings module in the _randbelow() method for classes without getrandbits(). Lazy import makes Python startup faster and reduces the number of imported modules at startup.
