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.)

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?

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:

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.

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.
