  • Status changed from new to needs_review

The patch rewires sage -gdb to use local/bin/sage-ipython, so the behavior will match the standard sage behavior more closely.

The Patch Buildbot can't apply the patchs:

hg qimport
adding trac_13669_fix_sage_gdb.patch to series file
hg qpush
applying trac_13669_fix_sage_gdb.patch
unable to find 'spkg/bin/sage' for patching
1 out of 1 hunks FAILED -- saving rejects to file spkg/bin/sage.rej

As say in,

Only the devel repository has branches, so the buildbot is unable to apply and try out patches to extcode/scripts/etc.

What should be done to review the patches?

From looking at them, they seem good to me, but I am no expert for gdb. And I can confirm that "sage -gdb" now starts without error, in the sense of "I was able to do some non-trivial computation in an interactive session and quit Sage without gdb complaining".

But is that enough to constitute a positive review?

comment:5 Changed 7 years ago by vbraun

I don't think there is anything to review, nor does this have anything to do with gdb really. Its just about starting up Python in the same way with or without gdb. The old sage-gdb script was very hackish.

comment:6 Changed 7 years ago by SimonKing

./sage -t -gdb devel/sage/sage/rings/polynomial/ works as well.

Slight complaint: ./sage -gdb -t devel/sage/sage/rings/polynomial/ does not work.

Would it be possible to make the options -gdb and -t commute?

comment:7 Changed 7 years ago by vbraun

The option parsing in general should be overhauled and probably based on the argparse Python module. Right now its a pain to extend the way options work.

See #21

So, here's your chance to fix a two-digit ticket...

comment:10 Changed 7 years ago by vbraun

Q: How many Sage contributors does it take to change a light bulb?

A: While looking at the broken light bulb we noticed some paint peeling on the wall, so we should probably re-do the foundation of the house first.

comment:11 Changed 7 years ago by SimonKing

The patches, when chosing to the right repositories, cleanly apply, and sage -gdb does start fine.

I'd say this is enough for a positive review.

Please use proper quoting:

gdb -x "$SAGE_ROOT/local/bin/sage-gdb-commands" -args python "$SAGE_ROOT/local/bin/sage-ipython" "$@" -i
