Hi! I read at http://www.sagemath.org/doc/developer/trac.html#reviewing-patches: "If someone (other than you) has posted a patch for a ticket on the trac server, you can review it!" Does that mean, if person A (say, Johan Sebastian Rosenkilde Nielsen) has a patch on trac (say, at #9976), and pers

[sage-devel] fix install_package() to do version-checking

2011-04-06 Thread Dima Pasechnik
Having optional package GLPK breaks things for people who try to install it by mistake. Simply removing it from the optional repository will break things for people who still run an old version of Sage, from the times it was still optional. Either we decide to drop supporting these users and remove

glpk is a standard spkg. Version 4.44, if I am right. So you seem to have tried installing an optional glpk version 4.42. This looks like a case for it to be removed. I already suggested this a while ago, but got a reply from someone that it's OK to keep it. Dima On Apr 7, 7:37 am, VictorMiller
