Hi all, With his permission... (Note that user/stephan/hacks/coroutines is by no way stable, according to Stephan.)

Author: arigo Date: Thu Dec 14 07:31:17 2006 New Revision: 35720

Added: pypy/dist/pypy/lib/stackless.py - copied unchanged from r35688, pypy/dist/pypy/lib/stackless.py pypy/dist/pypy/lib/stackless_new.py - copied unchanged from r35719, pypy/dist/pypy/lib/stackless.py Removed: pypy/dist/pypy/lib/stackless_old.py Log: Temporarily keep the old stackless.py. The new one seems to break all tests depending on it (at least its own test_stackless, and test_distributed).

Stephan: I suspect that you only tested it on top of CPython with your greenlet-based wrapper (could you check it in somewhere too, btw?). The behavior of this wrapper probably differs from the behavior of the module/_stackless coroutine in some way.

Arghhh. Actually, I ran ../../../test_all.py test_stackless.py from within the pypy/module/_stackless/test directory and it passed everything. Otherwise I wouldn't have replaced the stuff. Sigh. Anyway. All the stuff can be found in http://codespeak.net/svn/user/stephan/hacks/coroutine/ (the new stackless is called stackless2 :-) The tests I have there (test_stackless2.py) are passing when running on top of CPython, CStackless and pypy-c. (The secret plan is of course, to have the stackless interface available to CPython users --- minus the pickling, of course) The coroutine module is just the (old) interp_coroutine minus the parts that depend on pypy. I suspect that it could be made much, much thinner. Whenever this (greenlet based) coroutine is ready, I'd like to place it in py.magic. I'm really sorry about the breakage. pypy is really a difficult beast :-) Cheers Stephan P.S.: Unfortunatelly, I don't have any time left for this week, but I'll continue next week, to hunt down the bugs and complete the interface (and write much, much more tests as most features of stackless are not really covert yet)
