| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | different from what has been offered in libc_r (the one spotted in the original PR which is found in libthr has already been removed by David's commit, which is rev. 1.44 of lib/libthr/thread/thr_private.h): - Use POSIX standard prototype for ttyname_r, which is, int ttyname_r(int, char *, size_t); Instead of: char *ttyname_r(int, char *, size_t); This is to conform IEEE Std 1003.1, 2004 Edition [1]. - Since we need to use standard errno for return code, include errno.h in ttyname.c - Update ttyname(3) implementation according to reflect the API change. - Document new ttyname_r(3) behavior - Since we already make use of a thread local storage for ttyname(3), remove the BUGS section. - Remove conflicting ttyname_r related declarations found in libc_r. Hopefully this change should not have changed the API/ABI, as the ttyname_r symbol was never introduced before the last unistd.h change which happens a couple of days before.

* If an application closes one of its stdio descriptors (0..2),Ruslan Ermilov2003-05-311-2/+4
| | | | | | | | | | | | | | | | | | | | an excessive close() on one of these descriptors would cause a memory for this descriptor to be allocated in the internal descriptor table. When this descriptor gets used again, e.g. through the call to open() or socket(), the descriptor would be erroneously left in the blocking mode, and the whole application would get stuck on a blocking operation, e.g., in accept(2). Prevent this bug from happening by disallowing close() against non-active descriptors (return -1 and set errno to EBADF in this case).

* Fix threaded applications on ia64 that are linked dynamicly. We didMarcel Moolenaar2003-03-051-0/+1
| | | | | | | | | | | | | | | | | | | | not save (restore) the global pointer (GP) in the jmpbuf in setjmp (longjmp) because it's not needed in general. GP is considered a scratch register at callsites and hence is always restored after a call (when it's possible that the call resolves to a symbol in a different loadmodule; otherwise GP does not have to be saved and restored at all), including calls to setjmp/longjmp. There's just one problem with this now that we use setjmp/longjmp for context switching: A new context must have GP defined properly for the thread's entry point. This means that we need to put GP in the jmpbuf and consequently that we have to restore is in longjmp. This automaticly requires us to save it as well. When setjmp/longjmp isn't used for context switching, this can be reverted again. Notes: svn path=/head/; revision=111897
* Don't cast an int to a pointer type without (possibly) widening theMarcel Moolenaar2003-03-051-1/+1
| | | | | | | | | | | | | | integral type to the size of a pointer type when it's known that the cast is valid. On ia64 such casts are generally bad news and has led us (=peter :-) to make such casts fatal. By casting to intptr_t before casting to a pointer type, this now compiles cleanly in LP64 architectures. Note that the final cast has been changed to void* (instead of siginfo_t*) to make it explicit that we're not trying to pass a siginfo_t pointer but rather trying to pass an int when the prototype says it should be a pointer.

* Port libc_r to ia64. We need to do things slightly differentMarcel Moolenaar2003-01-064-0/+44
| | | | | | | | | | | | | | because we have 2 stacks per thread: the regular downward memory stack and the irregular upward register stack. This implementation lets both stacks grow toward each other. An alternative scheme is to have them grow away from each other. The alternate scheme has the advantage that both stack grow toward guard pages. Since libc_r is virtually dead and we really want the *context stuff for thread switching, we don't try to be perfect, just functional. Notes: svn path=/head/; revision=108753
