Comment:
Indeed, I have verified that all of the import time comes from importing
libgap. The new version of the patch looks good, and in particular the
new test for loading packages is much better.
Now checking (long) doctests, I find failures in 3 files:
{{{
----------------------------------------------------------------------
sage -t --long sage/combinat/designs/incidence_structures.py # 2 doctests
failed
sage -t --long sage/combinat/designs/design_catalog.py # 1 doctest failed
sage -t --long sage/coding/linear_code.py # 8 doctests failed
----------------------------------------------------------------------
}}}
The first two seem to be introduced by #14499; fixing these is now #14950
The failures in coding/linear_code are all in optional `gap_packages`
doctests, and they all have to do with the GUAVA package. My guess is
that these come from a version change or something similar, because guava
does load, and some guava-dependent doctests do work, such as
{{{
sage: C = HammingCode(5,GF(2))
sage: C.covering_radius() # optional - gap_packages (Guava package)
1
}}}
{{{
sage: C = HammingCode(3,GF(2))
sage: MS = MatrixSpace(GF(2),1,7)
sage: F = GF(2); a = F.gen()
sage: v1 = [a,a,F(0),a,a,F(0),a]
sage: C.decode(v1,algorithm="guava") # optional - gap_packages (Guava
package)
}}}
One failure comes from
{{{
sage: print bounds_minimum_distance(10,5,GF(2)) # optional - gap_packages
(Guava package)
}}}
This seems to give the same record as expected (see
[http://www.sagemath.org/doc/reference/coding/sage/coding/linear_code.html#sage.coding.linear_code.bounds_minimum_distance
here]), but the entries aren't printed in the correct order, hence causing
a doctest failure.
Another failure comes from
{{{
sage: MS = MatrixSpace(GF(2),4,7)
sage: G =
MS([[1,1,1,0,0,0,0],[1,0,0,1,1,0,0],[0,1,0,1,0,1,0],[1,1,0,1,0,0,1]])
sage: C = LinearCode(G)
sage: C.spectrum()
[1, 0, 0, 7, 7, 0, 0, 1]
sage: C.spectrum(algorithm="leon") # optional - gap_packages (Guava
package)
sh: /home/johnson.5320/sage/local/gap/latest/pkg/guava-3.12/bin/wtdist: No
such file or directory
---------------------------------------------------------------------------
RuntimeError Traceback (most recent call
last)
...
RuntimeError: Problem calling Leon's wtdist program. Install
gap_packages*.spkg and run './configure ../..; make'.
}}}
For this last error, I see that the file
`SAGE_ROOT/local/gap/latest/pkg/guava-3.12/bin/wtdist`
does not exist, but
`SAGE_ROOT/local/gap/latest/pkg/guava-3.12/bin/x86_64-unknown-linux-gnu-
gcc-default64/wtdist`
does exist. So probably this is an error coming from rearranging files.
I haven't checked the other failures here; I am inclined to believe that
fixing them belongs on a new ticket, but I'm not sure.
