[gentoo-science] [sage-on-gentoo] sage-notebook fix is in

[François Bissey]

Hi,

We have a fix for the sage-notebook thanks to a pointer from 
Steve. Steve pointed to pexpect and after careful examination 
and a few wrong turns we found the patch that sage applied to
make the notebook work.
It is ridiculously small but it does the job. So you can sync the overlay, 
make sure you package.keywords files are up to date and simply:
emerge -1uv pexpect
and voila working notebook.
Further tests welcome, since pexpect is used in quite a few things
we are looking to see if there could be side-effects.

François,

The patches to pexpect do allow the notebook to function. However, with the  
new patches to pexpect when I, from the notebook, do

	g=sin(x); plot(g,(x,-pi,3*pi/2))

I get

import os;os.chdir("/tmp/tmpo2KomY");
execfile("_sage_input_1.py")Python 2.6.4 (r264:75706, Mar  4 2010,
21:15:13)
[GCC 4.3.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 
>>> import os;os.chdir("/tmp/tmpo2KomY");
>>> execfile("_sage_input_1.py")
START1

import os;os.chdir("/tmp/tmpY61yjM");
execfile("_sage_input_2.py")

import os;os.chdir("/tmp/tmpXjmsQK");
execfile("_sage_input_3.py")
__SAGE__
__SAGE__import os;os.chdir("/tmp/tmpY61yjM");
__SAGE__execfile("_sage_input_2.py")
START2
__SAGE__
__SAGE__import os;os.chdir("/tmp/tmpXjmsQK");

The result should be the indicated graph in the notebook. So there still must  
be some functional differences between the pexpect-2.4-r1 in sage-on-gentoo  
and the pexpect-2.0_p4 provide by Sage.

Hi Steve,

Bummer. pexpect after 2.0 is a rewrite apparently. There is talk
about porting sage to a newer pexpect provided performance is
not abysmal. If it is broken, they may never want to upgrade.
Well I guess you just provided some material for discussion on sage-devel.
We may try a patched pexpect-2.0 for now, but that's a real pita.

Thanks for your testing Steve.

Hi,

I just uploaded pexpect-2.0 with fixes, but it does not seem to fix the 
problems with graphics - there is apparently more broken than just pexpect.

I was afraid it could be the case. I wonder if there is some "hardcoded" path 
in the sage-notebook.

Steve, did you get the graphics going with your simple pexpect ebuild using 
sage's sources?

Wait a minute - I did my own try here just now and it works.
I notice you didn't put eutils in your pexpect-2 ebuild, have the 
patches been applied?

Hi,

fortunately I was wrong:

I forgot to add EAPI=2 in pexpect-2.0, but now it should work (with graphics).

It works now here for me. Great job!
