Bumps setuptools from 83.0.0 to 84.1.0.

Changelog

Sourced from setuptools's changelog.

v84.1.0

Features

• setuptools.archive_util now raises the new UnsafeMember exception when an archive member would be extracted outside of the extraction directory, where previously such a member was silently skipped. Aborting makes a malicious or malformed archive visible to the caller instead of yielding a quietly incomplete extraction, and matches the behavior of the standard library's tarfile extraction filters.

Bugfixes

• Wheel.install_as_egg no longer creates namespace package directories outside of the destination egg directory. Entries in a wheel's namespace_packages.txt were split on . and passed straight to os.path.join, so an entry that was absolute, drive-qualified, or UNC discarded the destination and placed an __init__.py at a path chosen by the wheel. Namespace entries are now validated as dotted module names on every platform -- see GHSA-xmj3-9gf7-h52w.

  This code path is reached only by the deprecated setup_requires mechanism when setup() is invoked outside a PEP 517 frontend; the setuptools build backend never reaches it.

• setuptools.archive_util no longer extracts archive members outside of the requested extraction directory. Both the tar and zip formats specify / as the only path separator, but the guard against .. components split member names on / alone, so a name such as ..\escaped.txt was treated as a single component and then resolved as a traversal by the filesystem on Windows. Member names containing a backslash, a drive letter, or a UNC prefix are now rejected on every platform, as are members whose resolved destination falls outside the extraction directory -- see GHSA-grgh-hr87-3jpw.

v84.0.0

Features

• Newline-separated keywords and platformspypa/setuptools#4887old specification <https://peps.python.org/pep-0345/>_ separated items with spaces and the current one uses commas. (#4887)
• Extensionpypa/distutils#373#5022)
• The C compiler modules now emit log messages through their own compilers.C.* loggers instead of the distutils root logger, part of decoupling the compilers package from distutils. The logger names are normalized to a stable compilers.C.* prefix so they remain constant as the package migrates toward a standalone compilers.C distribution. (#5266)
• The C compilers gained a Compiler.call method -- a thin wrapper over subprocess.check_call (with macOS deployment-target env injection) that is the modern replacement for Compiler.spawn. The compilers no longer depend on distutils.spawn, distutils.dir_util, distutils.file_util, distutils._modified, or distutils.util.execute/split_quoted: the generic newer/newer_group and split_quoted helpers are vendored into the compilers package, and Compiler.mkpath/move_file/execute are implemented directly on the standard library (os.makedirs/shutil.move). The methods are retained for backward compatibility. (#5267)
• The compilers no longer depend on distutils.util, distutils.version, distutils.compat, or distutils._macos_compat. The platform-identification helpers (get_platform/get_host_platform/is_mingw) now live in distutils.compilers.platform.detect and the macOS deployment-target logic and compiler_fixup in distutils.compilers.platform.macos; CygwinCCompiler.gcc_version returns a packaging.version.Version. distutils.util re-exports the platform/macOS helpers from their new homes for backward compatibility rather than keeping duplicate copies. (sysconfig lookups still route through distutils pending its own decoupling.) (#5268)
• The compilers now read their build configuration from the standard library's sysconfig instead of distutils.sysconfig. Per-compiler customization -- previously distutils.sysconfig.customize_compiler -- has moved into Compiler.configure_system(): a no-op on the base class, with UnixCCompiler applying the compiler/flag/archiver settings CPython recorded in sysconfig (and the usual CC/CFLAGS/LDSHARED/… environment overrides). distutils.sysconfig.customize_compiler is retained as a thin wrapper that calls compiler.configure_system(). (#5269)
