* Properly decref on _pylong import error.
* Improve the error message on _pylong TypeError.
* Fix the assertion error in pydebug builds to be a TypeError.
* Tie the return value comments together.
These are minor followups to issues not caught among the reviewers on
https://github.com/python/cpython/pull/96673.
Now that our int<->str conversions are size limited and we have the
_pylong module handling larger integers, we don't need to limit
everything just to avoid wasting time in the quadratic time DoS-like
case while fuzzing.
We can tweak these further after seeing how this goes.
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
Fix use-after-free in Py_SetPythonHome(NULL), Py_SetProgramName(NULL)
and _Py_SetProgramFullPath(NULL) function calls.
Issue reported by Benedikt Reinartz.
Remove the keyfile, certfile and check_hostname parameters,
deprecated since Python 3.6, in modules: ftplib, http.client,
imaplib, poplib and smtplib. Use the context parameter (ssl_context
in imaplib) instead.
Parameters following the removed parameters become keyword-only
parameters.
ftplib: Remove the FTP_TLS.ssl_version class attribute: use the
context parameter instead.
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.
The function has been removed. In the ssl documentation, replace
references to the ssl.wrap_socket() function with references to the
ssl.SSLContext.wrap_socket() method.

In very rare circumstances the JUMP opcode could be confused with the
argument of the opcode in the "then" part which doesn't end with the
JUMP opcode. This led to incorrect detection of the final JUMP opcode
and incorrect calculation of the size of the subexpression.
NOTE: Changed return value of functions _validate_inner() and
_validate_charset() in Modules/_sre/sre.c. Now they return 0 on success,
-1 on failure, and 1 if the last op is JUMP (which usually is a failure).
Previously they returned 1 on success and 0 on failure.
The switch cases (really TARGET(opcode) macros) have been moved from ceval.c to generated_cases.c.h. That file is generated from instruction definitions in bytecodes.c (which impersonates a C file so the C code it contains can be edited without custom support in e.g. VS Code).
The code generator lives in Tools/cases_generator (it has a README.md explaining how it works). The DSL used to describe the instructions is a work in progress, described in https://github.com/faster-cpython/ideas/blob/main/3.12/interpreter_definition.md.
This is surely a work-in-progress. An easy next step could be auto-generating super-instructions.
**IMPORTANT: Merge Conflicts**
If you get a merge conflict for instruction implementations in ceval.c, your best bet is to port your changes to bytecodes.c. That file looks almost the same as the original cases, except instead of `TARGET(NAME)` it uses `inst(NAME)`, and the trailing `DISPATCH()` call is omitted (the code generator adds it automatically).
The uuid.getnode() function has multiple implementations, tested sequentially.
The ifconfig implementation was incorrect and always failed: fix it.
In practice, functions of libuuid library are preferred, if available:
uuid_generate_time_safe(), uuid_create() or uuid_generate_time().

The Python test suite now fails wit exit code 4 if no tests ran. It
should help detecting typos in test names and test methods.
* Add "EXITCODE_" constants to Lib/test/libregrtest/main.py.
* Fix a typo: "NO TEST RUN" becomes "NO TESTS RAN"
For wasmtime 2.0, the stack depth cost is 6% higher. This causes the default max `marshal` recursion depth to blow the stack.
As the default marshal depth is 2000 and Windows is set to 1000, split the difference and choose 1500 for WASI to be safe.
Use unnumbered footnote in this file to avoid reseting the footnotes numbering.
Example: when building the tutorial into a PDF and using `latex_show_urls = "footnotes"`; this footnote become the number 8. However, without this change, the footnote shows the number 1.
Fix subscription of type aliases containing bare generic types or types
like TypeVar: for example tuple[A, T][int] and tuple[TypeVar, T][int],
where A is a generic type, and T is a type variable.
This reduces confusion between jumps at the bytecode level
(e.g. JUMPTO(), JUMPBY(), and various JUMP_*() opcodes)
and jumps in the C code (which are 'goto' statements).
