Comment(by aginiewicz):
I looked trough doctest patch and compared it with mine from #8731, I have
few comments.
I think that doctest fix for sage/calculus/functional.py should be
modified - it was documentation of the use of assume, but now - when
maxima can calculate this integral without assumption, isn't that same as
applying assumption to result? And the integral is checked in other
doctest now. Maybe there is better example that still needs the assume to
get result?
Also the doctest in sage/misc/functional.py was here to demonstrate
numerical approximation of integral that cannot be evaluated iirc, and now
when it can be evaluated, I think it should be changed to something that
cannot be - like Jason did in patch in #8731.
Finally, there is typo in doctest to sage/symbolic/expression.pyx - it
should say that this doctest is here to check that #7334 not #7344 is
fixed (#7344 point to libjpeg issue so it cannot be it) - and it should
stay in here unmodified. Also - the log thing - it's not exactly
regression, it's feature. This is because of Maxima ticket 947808 -
http://sourceforge.net/tracker/?func=detail&aid=947808&group_id=4933&atid=104933
- they now try to keep the expression as factored as they can without
using factor. This results in observed behaviour. This doctest I think
cannot be changed as it demonstrated that ticket is solved, but we should
apply "x = x.simplify_rational()" after "x = x.simplify_log('one')" in
definition of simplify_full - that way full simplify would result in same
results as before I think, and #7334 would be still fixed. Now, this
doctest shows nothing.
