gh-98401: Invalid escape sequences emits SyntaxWarning (#99011)
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.
