Comment:
I have rebased the patch against `sage-4.8.alpha4`. This patch '''no
longer''' introduces the function `constraints()` that existed in the
previous patch, and that caused the conflict. It does not provoke any
doctest failures on my version of `sage-4.8.alpha4`.
However, I did notice that three doctest failures currently occur with
`sage-4.8.alpha4`:
{{{
File "/Applications/sage-4.8.alpha4/devel/sage-
main/sage/numerical/mip.pyx", line 523:
sage: p.show()
Expected:
...
File "/Applications/sage-4.8.alpha4/devel/sage-
main/sage/numerical/mip.pyx", line 685:
sage: p.write_lp(SAGE_TMP+"/lp_problem.lp")
Exception raised:
...
File "/Applications/sage-4.8.alpha4/devel/sage-
main/sage/numerical/mip.pyx", line 322:
sage: p
Expected:
...
}}}
Since these exist in an unpatched `sage-4.8.alpha4`, they have no bearing
on this ticket, but is this a known issue? I'll open a new ticket if not.
My machine is a MacBook Pro running OSX 10.6.8.
