''' Debian and other distributions "unbundle" requests' vendored dependencies, and rewrite all imports to use the global versions of ``urllib3`` and ``chardet``. The problem with this is that not only requests itself imports those dependencies, but third-party code outside of the distros' control too. In reaction to these problems, the distro maintainers replaced ``requests.packages`` with a magical "stub module" that imports the correct modules. The implementations were varying in quality and all had severe problems. For example, a symlink (or hardlink) that links the correct modules into place introduces problems regarding object identity, since you now have two modules in `sys.modules` with the same API, but different identities:: requests.packages.urllib3 is not urllib3 With version ``2.5.2``, requests started to maintain its own stub, so that distro-specific breakage would be reduced to a minimum, even though the whole issue is not requests' fault in the first place. See https://github.com/kennethreitz/requests/pull/2375 for the corresponding pull request.
