- Status changed from new to needs_review
it works already in Sage 9.1. I propose to resolve as "fixed".
comment:7 Changed 6 weeks ago by
somebody(?) should add a doctest, no ?
comment:8 Changed 6 weeks ago by
I can do it, but it's a long time I didn't contribute to Sage. Is there a howto somewhere?

humm, if you know git, this is simple. Otherwise, c'est moins simple.
there is the big developer manual, and in particular
https://doc.sagemath.org/html/en/developer/index.html#git-tricks-tips
in very short :
(1) clone the git repo and go to the develop branch
(2) set the remote to trac
(3) make a local branch on top of the develop branch
(4) push the branch to trac under u/your_trac_name/branch_name
(5) write that branch name in the ticket branch field

thanks, I've added a doctest, now running sage -t -all

si la branche est prete, le patchbot peut se charger de lancer les tests.

I get the following error while running the tests:

merci de pousser la branche sur trac, et d'écrire son nom dans le champ "branch" ci-dessus. On fera faire les tests par un patchbot.

it seems I don't have the right to push to trac (or I did the wrong command):

my remote says
~/sage$ git remote -v trac ssh://git@trac.sagemath.org:22/sage.git (fetch) trac ssh://git@trac.sagemath.org:22/sage.git (push)
Tro to use simply
git push trac HEAD:u/zimmerma/12419
EDIT: should use zimmerma, your user name here

ok, green bot
works now (sage 9.5.b0):
