Masayuki Yamamoto added the comment: I wrote a patch to avoid compile error for platforms that pthread_key_t is not integer. This patch changes to turn off Py_HAVE_NATIVE_TLS if pthread_key_t is not integer. Hence the platforms use TLS functions implemented by CPython self.
And, I would propose new thread local storage API based on C11 thread and current TLS functions move to deprecated. C11 tss_t doesn't require defined as integer [1]. Therefore I think new API should use tss_t, not hide into integer. [1] http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf (page 394) I'm thinking of new interfaces. For example, declaration in Include/pythread.h /* Specialise to each platforms using #if directive */ typedef /* TLS key types or C11 tss_t */ Py_tss_t; /* Based on C11 threads.h, but destructor doesn't support. the delete value function is maintained for the implementation by CPython self. */ PyAPI_FUNC(int) PyThread_tss_create(Py_tss_t *); PyAPI_FUNC(void) PyThread_tss_delete(Py_tss_t); PyAPI_FUNC(void *) PyThread_tss_get(Py_tss_t); PyAPI_FUNC(int) PyThread_tss_set(Py_tss_t, void *); PyAPI_FUNC(void) PyThread_tss_delete_value(Py_tss_t); ---------- Added file: http://bugs.python.org/file45548/configure-pthread_key_t.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25658> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
