Pip 8.1.2 doesnt find ndg_httpsclient extra subjectAltName_support

[jayvdb]

• Pip version: 8.1.2
• Python version: 2.7.12
• Operating System: Fedora 24

Description:

pip 8.1.2 installs ndg_httpsclient[subjectAltName_support], but emits
ndg-httpsclient 0.4.2 does not provide the extra 'subjectAltName_support' which is incorrect.

What I've run:

$ sudo python -m pip install 'ndg_httpsclient[subjectAltName_support]'

pyasn1 is a dependency of cryptography which pyOpenSSL has used since v0.14. I think the simplest solution is to remove the extras_requires and add pyasn1 as a core dependency to ndg-httpsclient.

[jayvdb]

Ubuntu precise is pyOpenSSL v0.12

[jayvdb]

Note that I am not objecting at all; just pointing out a relevant fact which might help you decide.

Forcing pyasn1 as a core dependency simplifies this packages support matrix, and means subjectAltName_support is mandatory - which is a good thing.

Could you check if pip install ndg_httpsclient[subjectaltname_support] works (note the lowercase) ?
If yes, this is a duplicate of #3810 which should be easy to fix.

It should have been fixed by #4037
