[pypy-dev] How to embed PyPy when there's no filesystem?

[tom at twhanson.com]

I'm confused about the relationship between SimpleIOSandboxedProc and 
VirtualizedSandboxedProc. 
 
Looking at pypy_interact.py I see that it is multiply dependent from 
SimpleIOSandboxedProc and VirtualizedSandboxedProc.  I expected that 
I'd be able to drop VirtualizedSandboxedProc and tweak the code in 
pypy_interact to get a controller that just did stdin/stdout.  But 
when I try that I get "out of memory" errors. 
 
It appears that SimpleIOSandboxedProc is not an independent, 
stand-alone class but is actually non-functional without the child 
class VirtualizedSandboxedProc.  Is that the intent?  Am I missing 
something?

I just said "statically into the binary" as an example. Of course you
can get the string from anywhere, like from reading an external
source. Once you got it into a "char *", you can pass it to
pypy_execute_source(). 

A bientôt,

Armin.
