Hi,
Some are known problems due to using different versions of certain
packages, example:
-%<-
File "/usr/share/sage/devel/doc/en/numerical_sage/cvxopt.rst", line 57:
sage: print(A)
Expected:

(2, 1) -1.0000e+00
(4, 1) 4.0000e+00
(1, 2) 4.0000e+00

(2, 3) 2.0000e+00
(1, 4) 6.0000e+00
(4, 4) 1.0000e+00

[ 0 0 1.00e+00 0 0 ]
[ 0 4.00e+00 2.00e+00 0 1.00e+00]

File "/usr/share/sage/devel/sage/sage/libs/pari/gen.pyx", line 6844:
sage: nf.nfroots(y^2 + 2)
Expected:

Got:
[Mod(-zz, zz^2 + 2), Mod(zz, zz^2 + 2)]
-%<-
Some are due to system wide installation, example:
-%<-

sage: b = builder.DocBuilder('tutorial')
Exception raised:

Some are somewhat strange, but I believe they are due to using some package
with different version, or missing some patch. Examples:
-%<-
File "/usr/share/sage/devel/sage/sage/matrix/matrix1.pyx", line 448:
sage: sorted(numpy.typecodes.items())
Expected:
[('All', '?bhilqpBHILQPfdgFDGSUVO'), ('AllFloat', 'fdgFDG'),

'FDG'), ('Float', 'fdg'), ('Integer', 'bhilqp'), ('UnsignedInteger',
'BHILQP')]
Got:
[('All', '?bhilqpBHILQPfdgFDGSUVOMm'), ('AllFloat', 'fdgFDG'),
('AllInteger', 'bBhHiIlLqQpP'), ('Character', 'c'), ('Complex',
'FDG'), ('Datetime', 'Mm'), ('Float', 'fdg'), ('Integer', 'bhilqp'),
('UnsignedInteger', 'BHILQP')]
-%<-
and
-%<-
File "/usr/share/sage/devel/sage/sage/sets/set.py", line 312:
sage: Primes() < Set(QQ)

Got:
False
-%<-
and
-%<
File "/usr/share/sage/devel/sage/sage/finance/time_series.pyx", line 1505:
sage: finance.TimeSeries([z.hurst_exponent() for z in y]).mean()
Expected:

Got:

-%<-
Some details that may be useful:
1) I am using a custom cPickle.so and pickle.py in $PYTHONPATH due to
sage's patches
2) I am using a custom sets.py in $PYHTONPATH that doesn't generate a
DeprecationWarning,
otherwise, the number of false positive positives due to
Deprecation warnings is too high...
3) I am using gmp5 instead of mpir (needs only a one line patch so far...)
4) I am using a newer givaro and python-mpmath, because other packages
resolved to
update those packages :-) So, I built a givaro patch, and used
mpmath patches from trac
I also found out that clisp maxima backend has a serious issue, in
that, for example it hangs
with the command:
sage: maxima.eval('x==x')
(as in sage/interfaces/maxima.py eval_line doctest)
and, probably because of the timeout and process kill, it causes some
other weird
doctest failures like:
-%<-
File "/usr/share/sage/devel/sage/sage/symbolic/relation.py", line 560:
sage: solve([cos(x)*sin(x) == 1/2, x+y == 0],x,y)
Expected:
[[x == 1/4*pi + pi*z38, y == -1/4*pi - pi*z38]]
Got:
[[x == 1/4*pi + pi*z39, y == -1/4*pi - pi*z39]]
-%<-
I reported the clisp problem upstream; last response:
https://sourceforge.net/mailarchive/forum.php?thread_name=4B8D57D2.4080002%40gnu.org&forum_name=clisp-devel
but the tests work with other lisp backends (only did not yet test gcl
from the available backends in Mandriva package)
