Comment:
This looks like a stacklevel mismatch between python and cython code. Some
other examples in pure python:
{{{
sage: numerical_sqrt(3)
/home/mjo/src/sage-5.0.beta1/local/bin/sage-ipython:1: DeprecationWarning:
numerical_sqrt is deprecated, use sqrt(x, prec=n) instead
#!/usr/bin/env python
sqrt(3)
}}}
{{{
sage: Polyhedron(vertices=[[0]]).union( Polyhedron(vertices=[[1]]) )
/home/mjo/src/sage-5.0.beta1/local/bin/sage-ipython:1: DeprecationWarning:
(Since Sage Version 4.4.4) The function union is replaced by convex_hull.
#!/usr/bin/env python
A 1-dimensional polyhedron in QQ^1 defined as the convex hull of 2
vertices.
}}}
If we pick something in a `*.pyx` file,
{{{
sage: p = m.copy()
/home/mjo/src/sage-5.0.beta1/local/lib/python2.7/site-
packages/IPython/iplib.py:2260: DeprecationWarning: the .copy() method is
deprecated; please use the copy() function instead, for example, copy(M)
exec code_obj in self.user_global_ns, self.user_ns
}}}
{{{
sage: x.lgamma()
/home/mjo/src/sage-5.0.beta1/local/lib/python2.7/site-
packages/IPython/iplib.py:2260: DeprecationWarning: The lgamma() function
is deprecated. Use log_gamma() instead.
exec code_obj in self.user_global_ns, self.user_ns
log_gamma(x)
}}}
(notice the iplib.py/sage-ipython difference). In a python file, the
stacklevel of EllipticCurve seems to be correct while the one for e.g.
lgamma() is off by one. Here's a test.py file:
{{{
from sage.all import *
print "Calling EllipticCurve..."
EllipticCurve(ZZ(1))
print "\nCalling x.lgamma()"
var('x').lgamma()
}}}
And running it:
{{{
$ sage test.py
Calling EllipticCurve...
test.py:4: DeprecationWarning: 'EllipticCurve(j)' is deprecated; use
'EllipticCurve_from_j(j)' or 'EllipticCurve(j=j)' instead.
EllipticCurve(ZZ(1))
Calling x.lgamma()
sys:1: DeprecationWarning: The lgamma() function is deprecated. Use
log_gamma() instead.
}}}
Adjusting the stacklevel fixes one, but breaks the other.
