Remove the distutils package. It was deprecated in Python 3.10 by PEP
632 "Deprecate distutils module". For projects still using distutils
and cannot be updated to something else, the setuptools project can
be installed: it still provides distutils.
* Remove Lib/distutils/ directory
* Remove test_distutils
* Remove references to distutils
* Skip test_check_c_globals and test_peg_generator since they use
distutils
A backslash-character pair that is not a valid escape sequence now
generates a SyntaxWarning, instead of DeprecationWarning. For
example, re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an
invalid escape sequence), use raw strings for regular expression:
re.compile(r"\d+\.\d+"). In a future Python version, SyntaxError will
eventually be raised, instead of SyntaxWarning.
Octal escapes with value larger than 0o377 (ex: "\477"), deprecated
in Python 3.11, now produce a SyntaxWarning, instead of
DeprecationWarning. In a future Python version they will be
eventually a SyntaxError.
codecs.escape_decode() and codecs.unicode_escape_decode() are left
unchanged: they still emit DeprecationWarning.
* The parser only emits SyntaxWarning for Python 3.12 (feature
version), and still emits DeprecationWarning on older Python
versions.
* Fix SyntaxWarning by using raw strings in Tools/c-analyzer/ and
wasm_build.py.
This got introduced in commit 5884449539
to determine if readline is already linked against curses or tinfo in
the setup.py, which is no longer present.
- pre-build Emscripten ports and system libraries
- check for broken EMSDK versions
- use EMSDK's node for wasm32-emscripten
- warn when PKG_CONFIG_PATH is set
- add support level information
- support EMSDK tot-upstream and git releases
- allow WASM assents for wasm64-emscripten and WASI. This makes single file distributions on WASI easier.
- decouple WASM assets from browser builds
Automate WASM build with a new Python script. The script provides
several build profiles with configure flags for Emscripten flavors
and WASI. The script can detect and use Emscripten SDK and WASI SDK from
default locations or env vars.
``configure`` now detects Node arguments and creates HOSTRUNNER
arguments for Node 16. It also sets correct arguments for
``wasm64-emscripten``.

This PR is required to reduce diffs of the following porting (no need to either maintain documentation and tests consistent with each porting step, or try to port everything and remove smtpd in a single PR).
Automerge-Triggered-By: GH:warsaw
wasi-env now sets WASIX flags. This allows us to control all build
parameter for wasm32-wasi buildbot from CPython repository.
Also export and improve SYSROOT parameter.
* Buffer standard input line-by-line
* Add non-root .editorconfig for JS & HTML indent
* Add support for clearing REPL with CTRL+L
* Support unicode in stdout and stderr
* Remove \r\n normalization
* Note that local .editorconfig file extends root
* Only normalize lone \r characters (convert to \n)
* Skip non-printable characters in buffered input
* Fix Safari bug (regex lookbehind not supported)

- c_longlong and c_longdouble need experimental WASM bigint.
- Skip tests that need threading
- Define ``CTYPES_MAX_ARGCOUNT`` for Emscripten. libffi-emscripten 2022-06-23 supports up to 1000 args.
* Move Lib/tkinter/test/test_tkinter/ to Lib/test/test_tkinter/.
* Move Lib/tkinter/test/test_ttk/ to Lib/test/test_ttk/.
* Add Lib/test/test_ttk/__init__.py based on test_ttk_guionly.py.
* Add Lib/test/test_tkinter/__init__.py
* Remove old Lib/test/test_tk.py.
* Remove old Lib/test/test_ttk_guionly.py.
* Add __main__ sub-modules.
* Update imports and update references to rename files.
- Emscripten's default umask is too strict, see
https://github.com/emscripten-core/emscripten/issues/17269
- getuid/getgid and geteuid/getegid are stubs that always return 0
(root). Disable effective uid/gid syscalls and fix tests that use
chmod() current user.
- Cannot drop X bit from directory.
- Mark more ``umask()`` cases
- ``dup()`` is not supported
- ``/dev/null`` is not available
- document missing features
- mark more modules as not available
* ``sys.executable`` is not set
* WASI does not support subprocess
* ``pwd`` module is not available
* WASI checks ``open`` syscall flags more strict, needs r, w, rw flag.
* ``umask`` is not available
* ``/dev/null`` may not be accessible
- WASI's ``gethostname()`` is a stub that always fails with OSError
``ENOTSUP``
- skip mailcap ``test`` if subprocess is not available
- WASI process_time clock does not work.
- fd inheritance can't be modified because Emscripten doesn't support subprocesses anyway.
- setpriority always fails
- geteuid no longer causes problems with latest emsdk
- umask is a stub
- geteuid / getuid always return 0, but process cannot chown to random uid.
- getgroups always fails.
- geteuid and getegid always return 0 (root), which confuse tarfile and
tests.
- hardlinks (link, linkat) always fails.
- non-encodable file names are not supported by NODERAWFS layer.
- mark more tests with dependency on subprocess and multiprocessing.
Mocking does not work if the module fails to import.
