* Fix ftell() to return EOVERFLOW if the file offset is greater thanmatthew2012-05-212-23/+10
| | | | | | | LONG_MAX. Also, remove an Alpha-specific optimization that only saves a couple of bytes of code size. ok millert, guenther
* More sysconf(3)-y and pathconf(3)-y goodness from Brad.matthew2012-05-143-45/+233
| | | | ok guenther, millert (and me); bulk build test by naddy
* The default device is selected with sndiod(1) or the AUDIODEVICEratchov2012-05-111-2/+2
| | | | | environment variable, so stop using the /dev/audio symlink which can't be used by sndiod(1) anyway

* Add pthread spinlock support.pirofti2012-05-0310-7/+387
| | | | | | | | | | | Implementation, documentation and naive regression tests for: - pthread_spin_init() - pthread_spin_destroy() - pthread_spin_lock() - pthread_spin_trylock() - pthread_spin_unlock() Implementation okay guenther@, documentation okay jmc@.
* Eliminate the f_usecount ref count in struct file; instead of sleepingguenther2012-05-011-2/+2
| | | | | | | | | at the top of closef() until all in-progress calls finish, just do the advisory locking bits required of close() by POSIX and let whichever thread has the last reference do the call to the file's fo_close() method and the final cleanup. lots of discussion with deraadt@ and others; worked out with and ok krw@
* Drop support from openpty() for 8+ year old kernels that don't supportmatthew2012-04-261-59/+5
| | | | | | | /dev/ptm. Users are strongly encouraged to upgrade to a more recent release if they haven't already. ok deraadt

* add missing defines, crucial: -DSQLITE_COREespie2012-04-221-1/+4
| | | | | used while compiling extensions which are actually a part of the core, prevents segfaults because extensions have not been loaded...

* Fix kvm_deadfile2_byid()'s handling of kernel vs user addresses forguenther2012-04-201-14/+43
| | | | | | | | fd_ofiles and fd_ofileflags, reading in the separate allocation when necessary. Lets fstat -p and fstat -u work on kernel crash dumps again. ok millert@

* Make it optional for kvm_getprocs() (and related sysctl) to returnpirofti2012-04-171-1/+9
| | | | | | | | | | | | thread information. Add a KERN_PROC_SHOW_THREADS flag that has to be set in order to get the thread info and make it off by default. This creates backwards compatibility for applications that relied on a given size/number of items to be returned. Modify ps(1) and top(1) accordingly. Okay guenther@.
* Remove "#define _POSIX_THREADS" line before include <pthread.h>.miod2012-04-172-6/+2
| | | | The latter contains "#define _POSIX_THREADS 1" which makes gcc 2.95 complain.
* Create a new resolver for each thread. It will be done differentlyeric2012-04-151-14/+24
| | | | | eventually, but it's enough for now to make the blocking API fully thread-safe without locking.

* extra src for us.espie2012-04-143-0/+4082
| | | | | | regen parse.c/parse.h with "lemon", no need to recompile every time. pthread_stub.c might(?) be needed for clean non-pthreads operation (to be checked, the nomutex stuff looks interesting)

* Add new mutex type, PTHREAD_MUTEX_STRICT_NP which checks for applicationkurt2012-04-142-6/+12
| | | | | | | | errors similar to PTHREAD_MUTEX_ERRORCHECK, however upon error it aborts. The rational is that many applications don't check the return values on pthread functions and will miss the errors that ERRORCHECK returns. PTHREAD_MUTEX_STRICT_NP will be our default mutex type for awhile okay guenther@ dcoppa@

* Import asr, an experimental async resolver implementation.eric2012-04-1416-0/+7184
| | | | | | | The idea is to eventually replace the existing resolver with something better. Time to start working on it in tree. ok deraadt@
* Provide _atomic_lock() and __cerror() for hppa64. Makes hppa64 build again.jsing2012-04-132-0/+74

* Use PTHREAD_MUTEX_DEFAULT in static init and mutexattr_init. If thekurt2012-04-132-7/+15
| | | | | | default mutex type changes to NORMAL, when there is an uninitialized mutex provided to unlock, allow it to succeed similar to an unlocked mutex. For other cases abort instead of segfault. okay guenther@
* Per POSIX, PTHREAD_MUTEX_NORMAL type mutexes have undefined behavior forkurt2012-04-131-7/+31
| | | | | | certain conditions. In the case of unlocking an unlocked mutex we will allow that to succeed, all other undefined behaviors will result in an immediate abort(). okay guenther@

| | | | | effective result. its use is NOT discouraged -- it is not common, but when you need it, there is nothing else that will do.
* Since threads are becoming more common, this "work around thederaadt2012-04-121-136/+0
| | | | | | compiler not doing alloca in C using malloc" is unworkable. It is not safe, and we can never use it. ok guenther kurt
* Add per thread accounting, mainly for usage & friends.pirofti2012-04-122-5/+40
| | | | | | | | | | | | | | This expands the already bloated FILL_KPROC macro to take an extra parameter that indicates if the callee is a thread or a process. The userland bits are adjusted accordingly and ps(1) and top(1) now display per thread usage times when -H is used. Also pkill(1) had to be adjusted so that duplicates don't pop up. libkvm does basically the same thing as the kernel bits. Okay guenther@.
