This is a known issue. We will try to implement a workaround. For now you need to have more swap available. Note that the swap will not actually be used if you have >= 2GB of RAM; it is really a limitation of some Linux configurations in which a process that consumes about half of the total amount of memory+swap cannot spawn new processes because os.fork() fails. A bientot, Armin.
Is there a direction, where I could digg to help? Something to begin with. I don't have enough experience but I'd like to take part (even very small) in this project. Armin Rigo wrote:

Sure. Do you understand the issue? It's related to the way a Unix process starts a new subprocess: os.fork() followed by os.execv() in the child process. The issue is that os.fork() fails if the parent process' total memory is more than half of your RAM+swap, because it tries to create a copy of the process, and the copy would also need more than half of your RAM+swap. (In reality, os.fork() doesn't copy the memory at all, but creates "shared pages" of memory so that memory pages are duplicated only when one of the two processes really modifies it; but still os.fork() has to mark all the memory as *potentially* used, and raises MemoryError if there isn't enough.) A solution might be to split translate.py in two processes: translate.py would start a subprocess when it starts, and then do all the work (consuming a lot of RAM); but when it needs to start new processes, e.g. call gcc, it would instead ask the subprocess to start the new processes. More precisely, the code in pypy.translator.tool.cbuild would stop using distutils directly, and instead ask the subprocess to use distutils. It looks even easy to do with the help of a py.execnet.PopenGateway() created when translate.py starts (see the py lib documentation at http://codespeak.net/py/). A bientot, Armin
Thanks a lot, Armin. I know how os.fork() works and about copy-on-write too, so as soon as I got time, I'll try to fix it. My interest in translating and playing then with pypy was exactly py.execnet =) Armin Rigo wrote:

Oh, sorry. Here are the details: launching pypy: ./pypy/bin/py.py then doing this: import py gw = py.execnet.PopenGateway() and getting that long long traceback.

Hi Vetoshkin, i think for translate.py you rather need to run py.execnet over CPython or through a translated pypy-c - both of which should work fine. I think you ran it through py.py which means starting a PyPy interpreter on top of CPython. Then running py.execnet.PopenGateway() would need to create another process that also runs through py.py - would be very slow - not sure it's worth trying to make it work. So i suggest you continue your experiments with plain CPython or the translated pypy-c. best & thanks, holger On Thu, Sep 04, 2008 at 01:43 +0600, Vetoshkin Nikita wrote:

good point - actually i just wanted to make the point that the translation tool chain (and py.execnet) should work fine on top of pypy-c, even if py.py fails. FWIW, I didn't see the other answers before i posted - using mutt over a high latency line i no fun, btw. holger
