[sage-devel] weil restriction for affine schemes as a functor?

2015-02-02 Thread Ben Hutz
I'm interested in implementing Weil restriction (restriction of scalars) for affine schemes. I see from #5569, that there is an implementation for ideals. I'd like to extend this to affine schemes/points/morphisms. There is also an aborted attempt of Weil restriction for projective models of el

I have a professional PyCharm license for sagemath.org development. The only issue is (or was) that it doesn't support all of Cython... apart from that, everything works very well. -- Harald On Friday, January 30, 2015 at 9:13:07 AM UTC+1, Ralf Stephan wrote: > > Hello, > I'm using IDEs for dev

Hello, I'm currently working on ticket #17254 and sometimes I introduce issues such that even if I fix them after a failed build trial, the relevant part gets not rebuild and I'm only be able to recover with a `make distclean` question: - how to recompile only the python and cython part (no

You are right, reference cycles with __del__ methods are treated differently from reference cycles without __del__ methods. The former are uncollectable in Python 2. On Sunday, February 1, 2015 at 12:00:13 PM UTC-5, Nils Bruin wrote: > So indeed, the running of __del__ methods is not guarantee

Re: [sage-devel] Trying to make sense of how sage uses GP

2015-02-02 Thread John Cremona
Julien, You did not need to modify anything, since there is already the facility to send all the gp commands to a log file. The default gp object is creted by the call gp=Gp() which has no log, but you can start up other instances, sage: gp = Gp(logfile="gp-log") sage: gp("2+2") 4 sage: -d Exiti
