Bumps setuptools from 81.0.0 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)

This doesn't actually have the intended effect. During install we'll use the latest setuptools anyhow, unless a setuptools version is already on the system. And during tests we are still stuck on old setuptools due to constraints in Devpi, or rather Pyramid. So we won't be able to update until Pyramid has released a fix for Pylons/pyramid#3731 or Devpi swapped out the dependency.
