* cthreads.h (hurd_condition_wait, condition_implies,
condition_unimplies): Restore decls lost in merge.
(mutex_clear): Define as mutex_init instead of bogon (lost in merge).
|
|
* cthreads.c (cthread_fork_prepare, cthread_fork_parent,
cthread_fork_child): Don't call malloc_fork_* (lost in merge).
|
|
|
|
* lockfile.c: Use __attribute__ magic instead of #pragma magic
for alias definitions. Don't bother to make them weak.

just include <strings.h> instead.
|
|
change, and my change to the toplevel configure.in that disables
versioning for the old stdio-using libc.
|
|
|
|
* libthreads.map: Define HURD_CTHREADS_0.3 version set,
putting all symbols there except the lockfile symbols.
* lockfile.c: Nit fixes.
|
|
|
|
Locking support for stdio streams with glibc-2.2 libio. EXPERIMENTAL!
* lockfile.c: New file.
* libthreads.map: New file.
* Makefile (SRCS): Add lockfile.c.
[$(VERSIONING) = yes] ($(libname).so.$(hurd-version)): Depend
on $(srcdir)/$(libname).map to get version script into the link.
|
|
|
|
* i386/csw.S: #undef __ELF__ before defining it, since
it is usually predefined.
|
|
|
|
* cprocs.c: Include <assert.h>
|
|
|
|
* cprocs.c (cproc_alloc): Initialize P->wired and P->msg here (code
from cthread_wire).
(cthread_wire): Reduce to just an assert, cthreads always wired.
(chtread_unwire): Abort if called.
|
|
|
|
* cthreads.h (MACRO_BEGIN, MACRO_END): #undef before unconditionally
redefining. Use GCC extension for statement expression with value 0.

|
* cthreads.h (mutex_clear): Change again, to call mutex_init.
|
|
|
|
* cthreads.h (mutex_clear): Change from syntax error to no-op (with
warning avoidance).
|
|
|
|
* cthreads.c (cthread_init): Move cthread_alloc call before
cproc_init call, since cthread_alloc uses malloc, and malloc won't
work between initializing the new stack and switching over to it.
