[Axiom-developer] RE: Tests of sage.

I am sorry that is has taken a bit of time but I promised to let you
know when the problem using Axiom with Sage that you reported back
in January is fixed. I just tried the new release 2.3 of Sage today
and I can confirm that the problem is gone, however I can not say
yet exactly what has changed in the new verison that makes this now
work for me.
In my testing the problem seemed to have something to do with the
communication between Sage and Axiom that is handled by an interface
For example in Sage on my OpenSuse 10.2 system after I typed an
Axiom command such as:
the system would hang until I pressed control-C. Thereafter, if I
repeated the command, or other Axiom commands, everything would work
The affect of this problem in the notebook() interface was more
severe since when the notebook tries to run the first Axiom command
there is no way to interrupt and restart this computation that did
not repeat the same problem.
The problem seemed to occur on some systems but not on others. For
example it failed for me on OpenSuse 10.2 linux but it works on the
axiom-developer.org server and William Stein told me a few weeks ago
that he could not reproduce the problem on his systems. Perhaps there
has been a subtle change in the way pexpect works. I will discuss
this with William.
In any case, you should be able to upgrade your installed version of
Sage to the latest version by the following simple command:
$ sage -upgrade
Sage will download all of the necessary updates and automatically
rebuild the system.
The version of Axiom I used for testing this was also installed using
Sage via the command:
$ sage -i axiom4sage-0.1.spkg
This downloads and builds a version of the Axiom build-improvments
branch dated '2006-10-10'. I hope to release a new package
'axiom4sage-0.2.spkg' based on the current source from the wh-sandbox
branch some time in the near future - sooner if anyone else expresses
some interest in this.
Please let me know if you have any more problems.
