[issue19553] PEP 453: "make install" and "make altinstall" integration

[Donald Stufft]

Donald Stufft added the comment:

1. This is bound to be an issue that stems from the fact pip is doing the install instead of distutils. It probably makes sense to use the group id of the parent directory I think?

2. This is a side effect of Wheel being a whole new way to install, previously pip just did setup.py install which took care of this bit. It shouldn't be a problem to make this happen.

3. Which sdist were you testing? The one from PyPI? We switched the style of that in 1.5 in order to better match how Python itself handles it versioned commands.

4. You mean when you do --default-install? (Or whatever it's called if Nick changed it).

5. I don't think any of us have ever run pip under a debug build of Python so that's probably why. It should probably be fixed up.

6. I'm not sure what the right answer is here. We recently switched pip to install using the default umask because previously it was using whatever permissions where in the archive. If the make file wants to control the permissions of the files can't it simply adjust the umask before calling ensurepip?

7. See the answer to #2.

8. I'll need to think about this, we don't want to blindly add --ignore-installed because we don't want ensurepip to downgrade pip if a newer version is installed.

Things that I see as issues so far I've created upstream tickets for, things that I still have questions on I didn't.
