I think this shouldn't go into 3.0.6 since it could introduce bugs, as it touches several files. That said, it's a smallish patch I made in 30 minutes. So it's not crazy complicated. It's just dangerous.

This patch causes some problems on my machine.
1) Sage segfaults at exit.
2) When doing sage -t, I get the following problem for every file:

Mike, (1) what is your system? (2) Can you do "sage -ba" and try again?

I just tried it out and got none of the problems described above.
'import sage.all' doesn't import IPython as desired. I'm not putting up a positive review because of the problems described above, but I would be nice to have feedback on this
I'm on OS X 10.5 with this patch applied against 3.1.4.

- Priority changed from blocker to major
If we've released for months and months (8 months!) without fixing this, it doesn't make sense to keep it as a blocker.

This is much easier now with the new IPython.
Apply trac_3685.patch

it seems that the doctest fails on 5.12.beta2, so the patch needs work

arggg, that breaks everything... Back to need work.. :(
comment:14 Changed 9 years ago by
I am not able to sort things out.
It seems that the import of IPython occurs because of the line
from IPython.core.formatters import PlainTextFormatter
in "sage.misc.displayhook"
Is there a way to avoid this IPython import ?

Outdated, should close
