From 870cc679771f776333953b2a990a107393d9d0fd Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 20 Apr 2011 21:41:45 -0400 Subject: fix minor bugs due to incorrect threaded-predicate semantics some functions that should have been testing whether pthread_self() had been called and initialized the thread pointer were instead testing whether pthread_create() had been called and actually made the program "threaded". while it's unlikely any mismatch would occur in real-world problems, this could have introduced subtle bugs. now, we store the address of the main thread's thread descriptor in the libc structure and use its presence as a flag that the thread register is initialized. note that after fork, the calling thread (not necessarily the original main thread) is the new main thread. --- src/thread/pthread_setcancelstate.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/thread/pthread_setcancelstate.c') diff --git a/src/thread/pthread_setcancelstate.c b/src/thread/pthread_setcancelstate.c index ebb6eba4..ba2b2311 100644 --- a/src/thread/pthread_setcancelstate.c +++ b/src/thread/pthread_setcancelstate.c @@ -3,7 +3,7 @@ int pthread_setcancelstate(int new, int *old) { if (new > 1U) return EINVAL; - if (libc.threaded) { + if (libc.main_thread) { struct pthread *self = __pthread_self(); if (old) *old = self->canceldisable; self->canceldisable = new; -- cgit 1.4.1
