* bpo-47061: document module deprecations due to PEP 594 (GH-31984)Brett Cannon2022-03-2126-22/+92
| | | Also removed asynchat, asyncore, and smtpd from their respective toctree entries so they are only in the superceded subtree.

| | | | | | | | * Atomic grouping: (?>...). * Possessive quantifiers: x++, x*+, x?+, x{m,n}+. Equivalent to (?>x+), (?>x*), (?>x?), (?>x{m,n}). Co-authored-by: Jeffrey C. Jacobs <timehorse@users.sourceforge.net>
* bpo-47040: improve document of checksum functions (gh-31955)Ma Lin2022-03-192-12/+9
| | | | | | | Clarifies a versionchanged note on crc32 & adler32 docs that the workaround is only needed for Python 2 and earlier. Also cleans up an unnecessary intermediate variable in the implementation. Authored-By: Ma Lin / animalize Co-authored-by: Gregory P. Smith <greg@krypto.org>

* bpo-47022: Document asynchat, asyncore and smtpd removals in 3.12 (GH-31891)Hugo van Kemenade2022-03-184-1/+10
| | | Document the deprecation of asyncore, asynchat, and smtpd with a slated removal in Python 3.12 thanks to PEP 594.
* bpo-45413: Define "posix_venv", "nt_venv" and "venv" sysconfig installation ↵Miro Hrončok2022-03-182-1/+19
| | | | | | | | | | | | | | | | | | | schemes (GH-31034) Define *posix_venv* and *nt_venv* sysconfig installation schemes to be used for bootstrapping new virtual environments. Add *venv* sysconfig installation scheme to get the appropriate one of the above. The schemes are identical to the pre-existing *posix_prefix* and *nt* install schemes. The venv module now uses the *venv* scheme to create new virtual environments instead of hardcoding the paths depending only on the platform. Downstream Python distributors customizing the *posix_prefix* or *nt* install scheme in a way that is not compatible with the install scheme used in virtual environments are encouraged not to customize the *venv* schemes. When Python itself runs in a virtual environment, sysconfig.get_default_scheme and sysconfig.get_preferred_scheme with `key="prefix"` returns *venv*.

* bpo-40059: Add tomllib (PEP-680) (GH-31498)Taneli Hukkinen2022-03-082-0/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new standard library module, `tomllib`, for parsing TOML. The implementation is based on Tomli (https://github.com/hukkin/tomli). ## Steps taken (converting `tomli` to `tomllib`) - Move everything in `tomli:src/tomli` to `Lib/tomllib`. Exclude `py.typed`. - Remove `__version__ = ...` line from `Lib/tomllib/__init__.py` - Move everything in `tomli:tests` to `Lib/test/test_tomllib`. Exclude the following test data dirs recursively: - `tomli:tests/data/invalid/_external/` - `tomli:tests/data/valid/_external/` - Create `Lib/test/test_tomllib/__main__.py`: ```python import unittest from . import load_tests unittest.main() ``` - Add the following to `Lib/test/test_tomllib/__init__.py`: ```python import os from test.support import load_package_tests def load_tests(*args): return load_package_tests(os.path.dirname(__file__), *args) ``` Also change `import tomli as tomllib` to `import tomllib`. - In `cpython/Lib/tomllib/_parser.py` replace `__fp` with `fp` and `__s` with `s`. Add the `/` to `load` and `loads` function signatures. - Run `make regen-stdlib-module-names` - Create `Doc/library/tomllib.rst` and reference it in `Doc/library/fileformats.rst`

| | | | | | For threads, and for multiprocessing, it's always been the case that ``args=list`` works fine when passed to ``Process()`` or ``Thread()``, and such code is common in the wild. But, according to the docs, only a tuple can be used. This brings the docs into synch with reality. Doc changes by Charlie Zhao. Co-authored-by: Tim Peters <tim.peters@gmail.com>
