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.
