Repeating a bot of what I added to PR13463 AIX has native support for thread-id since at least AIX 4.1 (1994-1995) where every process has an initial TID (PID are even numbers and "own" the resources, TID are odd and are the "workers" - very simply put). Hence, by default, an AIX process is "mono-threaded". The key concern - when calling thread related issues, is to ensure that all compiled code uses the same definitions in include files - namely, with _THREAD_SAFE defined. There are couple of ways to accomplish this: a) ensure that #include <pthread.h> is first (everywhere!) b) use cc_r, xlc_r, etc_r (with IBM compiler) c) -D_THREAD_SAFE As a) seems unpractical to ensure all the time; b) is also unpractical (no idea how/if gcc, e.g., has a way to 'signal' the need to be thread_safe - so a change in configure.ac, and maybe in setup.py, and thinking further yet - in the CFLAGS that get passed to extrnal modules and extensions - adding -D_THREAD_SAFE seems the most complete (aka safe) approach. And, of course, for this specific function a call to Syntax #include <pthread.h> pthread_t pthread_self (void); Description The pthread_self subroutine returns the calling thread's ID. ---------- nosy: +Michael.Felt _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36084> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
