Could PyPy have finalize() method or could be initialized thread by thread ?
From PyPy document, we should do the following: In main process: rpython_startup_code();
Hi, Our scenario is we had a main process, and it will create severl worker threads. Python code is running in worker threads. pypy_init_threads(); pypy_setup_home(...) And in worker thread that need to execute python code: pypy_thread_attach(); However, the problem is the code of the main process is in another module that we don't have source code access. So I am thinking could we do PyPy initialize and Finalize in thread itself? We could run python code in thread one by one. The process looks like: Main process create thread pool -> thread 1 initialized Pypy-> thread 1 run Python code -> thread 1 finish -> thread 1 finalize Pypy -> thread 2 initialized Pypy -> thread 2 run Python code -> thread 2 finish -> thread 2 finialize Pypy ... For now, if we do initialize again in thread 2, it will hang. And if we don't do initilize in thread 2, it will core dump by segmatation fault.

It's most probably fine to do the following in the thread: * first, acquire a lock to make sure there are no race conditions * if pypy has not been initialized so far: * rpython_startup_code(); * pypy_init_threads(); * pypy_setup_home(...) * any other initialization, like pypy_execute_source_ptr() * else: * pypy_thread_attach(); * release the lock * call python code A bientôt, Armin.
Hi Armin, I tried the following in one thread, and it hang in pypy_execute_source_ptr(). * rpython_startup_code(); * pypy_init_threads(); * pypy_setup_home(...) * pypy_execute_source_ptr() On Tue, Sep 8, 2015 at 7:40 PM, Armin Rigo <arigo@tunes.org> wrote:

I meant "do whatever you did so far here". I can't debug a new problem you get if I only know "it hangs"... A bientôt, Armin.
Hi Armin, Sorry for I didn't describe the problem clearly. The issue is well reproducible with the belolw simple piece of the code: #include ... int main() { rpython_startup_code(); pypy_init_threads(); pypy_setup_home(...); pypy_execute_source_ptr("print \'hello\'"); } It hangs in pypy_execute_source(). And if we remove "pypy_init_threads()", the code works. On Tue, Sep 8, 2015 at 9:19 PM, Armin Rigo <arigo@tunes.org> wrote:

do you have a minimal example where it doesn't work? did you try a very minimal program? On Tue, Sep 8, 2015 at 5:00 PM, Yicong Huang <hengha.mao@gmail.com> wrote:

Hi Maciej The minimal program is as below: nt main() { rpython_startup_code(); pypy_init_threads(); pypy_setup_home(...); pypy_execute_source_ptr("print \'hello\'"); } It hangs in pypy_execute_source(). And if we remove "pypy_init_threads()", the code works.

Finally, we found out in this case we also need to call pypy_setup_home() in the thread attach.
