Here is a far more baffling one:

Not Implemented: sandboxing for external function 'pypy_jit_depthmap_add'

That's certainly not something I would expect the controller process to implement. It seems to happen after a bunch of repetitive commands (when I suppose JIT is kicking in).

BTW, I did not run into either of these issues with a build from a year ago, around commit 72100.

If anyone can suggest what I might be doing wrong, I would greatly appreciate.

Hi!

I am getting this error from the sandbox:

Not Implemented: sandboxing for external function 'fcntl'

I am using a custom controller process, and getting this in fdopen (pypy_interact bombs on something else before it gets to that point). After much digging, I think this is due to _check_fd_mode function in rpython/rlib/streamio.py. In sandbox mode, I think there is little use for this check, but since it's there, I need some workaround. Does anyone have recommendations?

More generally, my team needs to decide if we can rely on the pypy sandbox to use in our product. It seems brilliantly designed, fast, and overall impressive. But there are these gaps in missing sandbox wrappers (there are others too, fcntl is just one that I don't know how to avoid). And I noticed some code that indicates that it is not supported on Windows -- is that the case?

What are the sandbox's prospects, within the larger future of pypy?
