Switch from setuptools to Distribute

[craigcitro]

Distribute is a fork of setuptools that aims to be open and actively maintained. It's also run by a handful of core Python devs.

There's a new spkg file, as well as updates to spkg/install and spkg/standard/deps. All three are sitting in this directory:

 http://sage.math.washington.edu/home/craigcitro/distribute-spkg/

To test, delete the setuptools spkg, drop in the new install and deps, and then build sage. (Or, alternately, build the two spkgs that currently depend on setuptools -- Jinja and SQLAlchemy.)

[craigcitro]

I should say -- I've currently got a build from scratch running on my machine; I'll report any trouble I run into.

It worked fine for me on sage.math, but with a 64-bit build on Mac OS X 10.5, it didn't: when it tried to build Sphinx, it couldn't find Jinja. (Then I very cleverly deleted the log file, so I can't reproduce the exact error message. I'm building again, trying both 32- and 64-bit, and I'll post the error message assuming I get it again.)

Also, #6586 has just been merged in to 4.2.alpha0, and this includes jinja2 (in addition to jinja). Do you need to modify deps and install to deal with jinja2?

[craigcitro]

Yep, it failed on my Mac, too. I have no idea why: it's having trouble finding the Jinja egg, which is there in site-packages, and is listed in easy_install.pth! Here's the error message:

error: Could not find required distribution Jinja>=1.1

It's clearly trying to go out and grab a dependency from the internet -- but I don't know why. In theory, that dependency should be provided already ... here's easy_install.pth:

import sys; sys.__plen = len(sys.path)
./distribute-0.6.6-py2.6.egg
./Jinja-1.2-py2.6-macosx-10.3-i386.egg
./Pygments-0.11.1-py2.6.egg
./Sphinx-0.5.1-py2.6.egg
import sys; new=sys.path[sys.__plen:]; del sys.path[sys.__plen:]; p=getattr(sys,'__egginsert',0); sys.path[p:p]=new; sys.__egginsert = p+len(new)

It's identical to the easy_install.pth installed via setuptools; I have no idea why it's failing.

[jhpalmieri]

Well, I couldn't reproduce that error because I got one when trying to build jinja; it's still trying to use setuptools:

---------------------------------------------------------------------------
This script requires setuptools version 0.6c5 to run (even to display
help).  I will attempt to download it for you (from
http://cheeseshop.python.org/packages/2.6/s/setuptools/), but
you may need to enable firewall access for this script first.
I will start the download in 15 seconds.

(Note: if this machine does not have network access, please obtain the file

   http://cheeseshop.python.org/packages/2.6/s/setuptools/setuptools-0.6c5-py2.6.egg

and place it in this directory before rerunning this script.)

I get this with both 32-bit and 64-bit.

As I said earlier, I've also seen a different error -- it got a little farther and bombed when it reached Sphinx, and it was trying to download Jinja1.2. In that case, there were files "setuptools.pth" and "setuptools-0.6....egg" in SAGE_ROOT/local/lib/python/site-packages by the time the build failed.

This can be closed: #11363 has made it redundant.
