Here are 2 distinct problems, that look similar. (1) The new trac seems to have broken the patchbots, with the following traceback. Maybe just because of https, but not sure. Traceback (most recent call last): File "sage_patchbot/patchbot.py", line 997, in test_a_ticket File

Hi everyone, I would like to discuss adding at least one more testing method to the sage development process than just doctests (e.g. nose). Doctests are certainly great but they have obvious limitations. Some of them are: 1) You want to keep the source code clean so doctests should be

there is an issue related to "native git" protocol used to communicate with git server on trac.sagemath. Namely, if you try to use the URL git://trac.sagemath.org/sage.git for (say) fetch it does not get through. (probably a GCE firewall blocks the corresponding port). Using the ssh URL, i.e.

You should sign up for the sage-flame group, which is specifically designed for that sort of discussion. Or you could perhaps even set up sagemathcloud-flame. In my opinion, sage-devel should be for discussing the development of Sage. Bill. On Monday, 13 June 2016 11:19:09 UTC+2, Nathann
