I'd actually prefer for Linux to not use the bundled certs when installed from a package manager because it should use the system certs, but people can't depend on certs being there if they are only there on linux. Adding them into Python means people _can_ depend on them being there, and Windows and other systems without system integrators to modify it to use the system store will still get certs and Ubuntu can make it just work(™). > > -Barry > > [1] This gives us headaches in upstreams like coverage caused by bundling > externally available JavaScript libraries, or like urllib3 bundling chardet > and urllib3, not to mention their own certificates yet again. :( This would probably (eventually) make the bundling of certificates better too. Meaning that once it's been in long enough people are willing to depend on it, they won't need to bundle their own certs and ubuntu/debian can just modify the one location instead of needing to modify it for every package that does it. > _______________________________________________ > Python-Dev mailing list > Python-Dev@python.org > http://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: > http://mail.python.org/mailman/options/python-dev/donald%40stufft.io ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
