+ * pthread.h (struct pthread_once_t_): Qualify the 'done' element + as 'volatile'. + * pthread_once.c: Concerned about possible race condition, + specifically on MPU systems re concurrent access to multibyte types. + [Maintainer's note: the race condition is harmless on SPU systems + and only a problem on MPU systems if concurrent access results in an + exception (presumably generated by a hardware interrupt). There are + other instances of similar harmless race conditions that have not been + identified as issues.] - * builddmc.bat: New; Windows bat file to build the library. - * config.h (__DMC__): Support for Digital Mars compiler. - * create.c (__DMC__): Likewise. - * pthread_exit.c (__DMC__): Likewise. - * pthread_join.c (__DMC__): Likewise. - * ptw32_threadDestroy.c (__DMC__): Likewise. - * ptw32_threadStart.c (__DMC__): Likewise. - * ptw32_throw.c (__DMC__): Likewise. +2004-09-09 Ross Johnson <rpj at callisto.canberra.edu.au>

+ tests in an attempt to improve efficiency and remove a race
+ condition.
- * pthread.h (HAVE_STRUCT_TIMESPEC): If undefined, define it - to avoid timespec struct redefined errors elsewhere in an - application. +2004-08-23 Ross Johnson <rpj at callisto.canberra.edu.au>
-2004-06-21 Ross Johnson <rpj at callisto.canberra.edu.au> + * create.c (pthread_create): Don't create a thread if the thread
+ id pointer location (first arg) is inaccessible. A memory
+ protection fault will result if the thread id arg isn't an accessible
+ location. This is consistent with GNU/Linux but different to
+ Solaris or MKS (and possibly others), which accept NULL as meaning
+ 'don't return the created thread's ID'. Applications that run
+ using pthreads-win32 will run on all other POSIX threads
+ implementations, at least w.r.t. this feature.
- * pthread.h (PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Mutex - initialiser added for compatibility with Linux threads and - others; currently not included in SUSV3. - * pthread.h (PTHREAD_ERRORCHECK_MUTEX_INITIALIZER): Likewise. - * pthread.h (PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP): Likewise. - * pthread.h (PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP): Likewise. + It was decided not to copy the Solaris et al behaviour because,
+ although it would have simplified some application porting (but only
+ from Solaris to Windows), the feature is not technically necessary,
+ and the alternative segfault behaviour helps avoid buggy application
+ code.
