[Python-Dev] [ANN] Daily Windows builds of Python 3.x

[Steve Dower]

Hi all

As part of a deal with Zach Ware at PyCon, I agreed that if he removed 
the Subversion dependency from our builds, I would set up daily Windows 
builds of Python. Zach did an excellent job, and so I am now following 
through on my half of the deal :)

For a while I've been uploading the official releases to nuget.org. 
These packages can be installed with nuget.exe (latest version always 
available at https://aka.ms/nugetclidl), which is quickly becoming a 
standard tool in Microsoft's build toolsets. It's very much a CI-focused 
package manager, rather than a user-focused one, and CI on Windows was 
previously an area where it was difficult to use Python.

See the official feed at https://www.nuget.org/packages/python, and 
related packages pythonx86, python2 and python2x86.

For people looking for an official "no installer" version of Python for 
Windows, this is it.


And since all the infrastructure was there already, I decided to publish 
daily builds in a similar way to myget.org:

     https://www.myget.org/feed/python/package/nuget/pythondaily

To install the latest daily build, run nuget.exe with this command:

     nuget.exe pythondaily -Source 
https://www.myget.org/F/python/api/v3/index.json

(Note that if you already have a "pythondaily" package in that 
directory, nuget will consider the requirement satisfied. As I said, 
it's meant for reproducible CI builds rather than users who want to 
update things in the least amount of keystrokes :) )

The sys.version string contains the short commit hash. Please include 
this string when reporting bugs in these builds. Also, only the amd64 
Release build is available pre-built.

     >>> sys.version
     '3.7.0a0 (remotes/origin/master:733d0f63c, Aug  8 2017, 15:56:14) 
[MSC v.1900 64 bit (AMD64)]'

Hopefully this is valuable for people who want to include daily builds 
in their own test runs or validate recent bug fixes.

Cheers,
Steve
