maybe another (untested) suggestion is, to start a sage instance in
background, separated from django and communicate over a network
protocol with each other.
this has the further advantage, that you can separate the web-server
from the sage installation for security of performance reasons.

Ok, cool; as I'm looking around more, it's seeming like getting a good
grasp of how the cell server is working and using or adapting it
appropriately. Will keep on hacking.

This is somewhat scary ;-) You can execute arbitrary machine code from
within Sage, so you need to have a plan for how to isolate it from the web
frontend. Importing it all into one process is a bad idea.

Hm, the issue is that there's really big startup costs for Sage; it looks
based on my cursory understanding of subprocess that there's a couple
seconds of hang-time for each calculation one wants to execute. This
doesn't really scale. I know there's something involving spawning a pile
of kern
You could just use call from the Python subprocess module, which is
documented in the Python docs. It depends on exactly what functionality
you need from Sage.

Ok, the patch maybe works. Sage starts normally after patching, but I'm
getting a segfault from the django process when I try to load a webpage, so
not sure what that's about
Is there documentation or good examples somewhere on how to use Sage as a
subprocess?

Cool, I'll give the patch a shot. It looks like some other projects have a
variable or option for disabling interrupts for exactly this reason; if a
patch works, it might make sense to do signals optionally in Sage.

Hello!
I'm trying to run Django inside of the Sage python and import the sage
libraries. (Idea: "Hey, look, a web server that can find derivatives!")
The Django install into my Sage install went fine, but I'm getting an

Hi,
I have been revisiting some process control code in Knoboo, and
realized
how well Sage responds to SIG-INT compared to standard Python. It
basically
works too good... ;)
Can somebody point me to the most relevant pieces of code/
documentation
concerning signal handling in Sage so I can learn
