Comment(by aginiewicz):
As sooner or later maxima would have to be updated to 5.22 or newer I
decided to share my experiences of first approach to update to it. I
wanted to try 5.22 because it's first version that supports inversion of
error function, and first to support integrals of form abs(x) from 0 to a
without assumptions. I based on patch by Jason for 5.21 and wanted to
reach at least same level of failures as with 5.21. Unfortunately, I got
stuck at one place - maxima hangs in some situations. I tracked that to
this difference:
before it was
{{{

and now it is
{{{

which makes Sage wait for "<sage-display>" forever.
I made spkg: http://lab15.im.pwr.wroc.pl/~giniew/maxima-5.22.1.spkg and
patch - http://lab15.im.pwr.wroc.pl/~giniew/trac-8731-maxima-upgrade-
to-5.22.1.patch - those are not working but I'm attaching them in case
someone wants to pick up from here - as I said I gave up for now.
(btw, the doctest that was failing in devel/sage/sage/calculus/calculus.py
is just different grouping, checked it and added new version to doctest,
and there is one new doctest failure in
devel/sage/sage/calculus/calculus.py that fails because maxima can
integrate abs(x) in x from 0 to any a and returns correct 1/2*a*abs(a).
There was also change to how logcontract works, they don't make full
rational simplification now. I added one more step of rational
simplification to simplify_full to simplify it more, though it might
change some results.)
