Hi all,
I've been out of the Sage loop for a while, but upon upgrading to 5.10, I
found that Maxima seems to choke on the following innocuous code which used
to run fine. I'm posting this here, because this issue came up while I was
working on #10132, and also because it affects usability.
sage: u, v = var('u,v')
sage: assume(u, 'real')
sage: assume(v, 'real')
sage: assume(u^2 + v^2 < 1)
sage: n = vector((u/sqrt(-u^2 - v^2 + 1), v/sqrt(-u^2 - v^2 + 1), 1))
sage: norm = n.norm(); norm
sqrt(abs(u/sqrt(-u^2 - v^2 + 1))^2 + abs(v/sqrt(-u^2 - v^2 + 1))^2 + 1)
sage: norm.simplify_full()
The last command just sits there on 5.10, and consumes all the resources
(more specifically, /Users/Joris/sage/local/bin/sage-cleaner consumes all
the available memory). In Sage 5.3, the last command just would return
I/sqrt(u^2 + v^2 - 1) which is not very nice but at least it's short and
fast.
Is this known? Is there something I can do to avoid this?
All the best,
Joris
