New Revision: 189828
URL: http://svn.freebsd.org/changeset/base/189828
Log:
Fix the visibility of several prototypes. Also move pthread_kill() and
pthread_sigmask() to signal.h. In principle, this shouldn't break anything,
[...]
But it did break, see http://www.freebsd.org/cgi/query-pr.cgi?pr=132828
I think one's namespace shouldn't be polluted with the prototype of
pthread_kill() if he has not included pthread.h.
The pthreads API has always defined pthread_kill() to be in
signal.h, not pthread.h. This is what is done in glibc and
elsewhere.
GNU Pth has some bogus and extremely unportable hacks to ``trick''
system headers into not declaring symbols:
/*
* Prevent system includes from implicitly including
* possibly existing vendor Pthread headers
*/
#define PTHREAD
#define PTHREAD_H
#define _PTHREAD_T
#define _PTHREAD_H
#define _PTHREAD_H_
#define PTHREAD_INCLUDED
#define _PTHREAD_INCLUDED
#define SYS_PTHREAD_H
#define _SYS_PTHREAD_H
#define _SYS_PTHREAD_H_
#define SYS_PTHREAD_INCLUDED
#define _SYS_PTHREAD_INCLUDED
#define BITS_PTHREADTYPES_H
#define _BITS_PTHREADTYPES_H
#define _BITS_PTHREADTYPES_H_
#define _BITS_SIGTHREAD_H
The one that works for glibc is _BITS_SIGTHREAD_H. I'd rather not
be complicit in these shenanigans, but if we can't easily fix the
problem in Pth, I suppose we can teach signal.h about one of these
bogus macros. What do you think?
Dumb question, why do we need devel/pth? Isn't the native pthread
support sufficient?
