2007-10-01Always install libpthread.* symlinks if at least one ofRuslan Ermilov
the threading libraries is built. This simplifies the logic in makefiles that need to check if the pthreads support is present. It also fixes a bug where we would build a threading library that we shouldn't have built: for example, building with WITHOUT_LIBTHR and the default value of DEFAULT_THREADING_LIB (libthr) would mistakenly build the libthr library, but not install it.

2007-05-13Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it.Daniel Eischen
Warning, after symbol versioning is enabled, going back is not easy (use WITHOUT_SYMVER at your own risk). Change the default thread library to libthr. There most likely still needs to be a version bump for at least the thread libraries. If necessary, this will happen later. Notes: svn path=/head/; revision=169524

2006-12-18Clean bound and non-bound pthread structures consistently beforePeter Edwards
they become candidates for reuse. Without this fix, some of the state from a thread structure's previous incarnation could interfere with its new one. Specifically, a non-bound thread started as "suspended" (see pthread_attr_setcreatesuspend_np()) might not get scheduled at all when resumed, as the "active" flag would be set spuriously.

2006-09-01Stylize:Marcel Moolenaar
o avoid using a global register variable. o redefine struct ia64_tp as a union. We don't have to get to the fields themselves. We just need it to be of the right size with the right alignment. Notes: svn path=/head/; revision=161841
2006-09-01The ucontext is 16-byte aligned, which means that struct tcb isMarcel Moolenaar
16-byte aligned. Consequently, struct tcb is a multiple of 16 bytes in size. We need to make sure there's no padding after struct ppc32_tp. We do this by explicitly adding the necessary padding in front of it. Notes: svn path=/head/; revision=161830

* Add posix_memalign(). * Move calloc() from calloc.c to malloc.c. Add a calloc() implementation in rtld-elf in order to make the loader happy (even though calloc() isn't used in rtld-elf). * Add _malloc_prefork() and _malloc_postfork(), and use them instead of directly manipulating __malloc_lock.

functions in the child after a fork() from a threaded process, use __sys_setprocmask() rather than setprocmask() to keep our signal handling sane. Without this fix, signals are essentially ignored in said child and things such as protection violations result in an endless busy loop. Reviewed by: deischen Notes: svn path=/head/; revision=153989

2005-09-24Modify the code path of the ifdef NOTYET part of _kse_single_thread():Brian Somers
o Don't reinitialise the atfork() handler list in the child. We are meant to call the child handler, and on subsequent fork()s should call all three functions as normal. o Don't reinitialise the thread specific keyed data in the child after a fork. Applications may require this for context. o Reinitialise curthread->tlflags after removing ourselves from (and reinitialising) the various internal thread lists. o Reinitialise __malloc_lock in the child after fork() (to balance our explicitly taking the lock prior to the fork()). With these changes, it is possible to enable the NOTYET code in thr_kern.c to allow the use of non-async-safe functions after fork()ing from a threaded program.
