4. (if time permits) Move any dependency resolution code out into a
separate library.

   This would make it possible for other projects (like buildout or a
future pip replacement) to reuse the dependency resolver.


Thank you!


Welcome!


...

I do intend to reuse some of the work done by Robert Collins in PR #2716 on
pip's GitHub repository.


Are you aware of the proof of concept in distlib?


I am. I had looked at it a few weeks back. IIRC it makes a dependency graph
using distlib and operates with that.

I haven't really understood how it gets the information about dependencies
without downloading the packages... I'll give it another pass this weekend.

If I recall, it reads static dependency data held on the red-dove site
and maintained by downloading and running egg-info on the packages as
changes occur. I don't think it's a sustainable approach for pip at
the moment (my understanding is that it was a proof of concept for
what having static metadata on PyPI would gain us).

Great news !

Your plan seems reasonable.
The first stage (RequirementSet refactor) seems to me to be the trickiest.

Anyway I'm looking forward for your PRs :)

[Distutils] win amd_x64 Python 2.7.8 --> 2.7.13 woes

[Robin Becker]

I find my extensions compiled for windows amd_x64 with python 2.7.8 no longer 
work after I updated python to 2.7.13.


Is that expected? I had assumed that the cpy27 wheels  that I make would work 
with any python 2.7, but this makes me doubt that.


To get the reportlab tests to complete I rebuilt all my extensions and installed 
a newer version of pillow.


In addition to that the uninstallation of the amd64 python 2.7.8 has also 
uninstalled the x86 version of python 2.7.8 :(

[Robin Becker]

Ignore this; it was my duh :( of the day; seems the download button didn't
give me the amd_x64 version so it carefully installed an x86 where I used
to have my amd_x64. After banging my head with a hammer I downloaded the
installers carefully and got things back to normal.

I see pip is not yet listed as a PSF sub-org on http://python-gsoc.org/.
This is pretty urgent to arrange:

*"March 3* - Last day for Python sub-orgs to apply to participate with
the PSF.
(Assuming we get accepted by Google and can support sub-orgs, of
course!)
This deadline is for orgs who applies on their own and didn't make it,
but still
 wish to participate under the umbrella. "

The original deadline was Feb 7. There's a good chance that Pip will still
be accepted after March 3, but I wouldn't gamble on it.

There are instructions under "Project Ideas" on http://python-gsoc.org/ on
how to get accepted as a sub-org.

Cheers,
Ralf

Oh. I’ve never done this before and Pradyun reached out so I had no idea I had 
to do this. I’ll go ahead and do this.

[Pradyun Gedam]

Thanks for the pointer Ralf! :)

I was actually drafting a mail to send to Donald directly for thanking him
for being willing to mentor me as well as pointing this out to him.

I guess I can discard that draft now...

I'm the GSoC admin for SciPy, so need to keep track of the various
deadlines/todos. I'd be happy to ping you each time one approaches if that
helps.

There's a PSF GSoC mentors list that's not noisy and useful to join. You'll
be added to the Google GSoC-mentors list automatically if you start
mentoring in the program, but you may want to mute it or not use your
primary email address for it (it's high-traffic, very low signal to noise
and you can't unsubscribe).
