Comment(by kcrisman):
I can't even begin to say where these are from... but
{{{
sage/misc/citation.pyx", line 60:
sage: get_systems('integrate(x^2, x)')
Expected:
['ginac', 'Maxima']
Got:
['MPFI', 'ginac', 'Maxima']
}}}
{{{
sage/symbolic/random_tests.py", line 206:
sage: random_expr(5, verbose=True)
Expected:
About to apply <built-in function add> to [v1, v1]
About to apply <built-in function div> to [-1/3, 2*v1]
-1/6/v1
Got:
About to apply <built-in function add> to [v1, v1]
About to apply <built-in function div> to [94, 2*v1]
47/v1
}}}
seem to be related to just random changes in 4.3.1, while
{{{
sage/functions/generalized.py", line 239:
sage: t.subs(x=1)
Expected:
2
Got:
heaviside(x) + 1
}}}
and a few friends seem to be related to something in pickling changing (I
get no other errors with things like that).
In addition, I am getting quite a few segfaults when testing against
4.3.1.
{{{
Desktop/sage-4.3.1/sage -t devel/sage/sage/calculus/calculus.py
devel/sage/sage/functions/piecewise.py devel/sage/sage/plot/plot.py
devel/sage/sage/symbolic/expression.pyx devel/sage/sage/misc/functional.py
devel/sage/sage/symbolic/relation.py
devel/sage/sage/symbolic/assumptions.py devel/sage/sage/calculus/wester.py
devel/sage/sage/calculus/functional.py
}}}
all do. Probably I should not have applied all patches at once, but I was
impatient :)
