* Make the pthread scheduler block signals while restoring a newlystsp2011-01-251-1/+12

* Change basep parameter of getdirentries() to be off_t *, not long *millert2010-10-282-4/+4
| | | | | | | | so it works correctly with large offsets (and matches other systems). This requires adding a new getdirentries syscall, with the old one renamed to ogetdirentries. All in-tree consumers of getdirentries() have been updated. Bump libc and libpthread major numbers. OK and with deraadt@
* Fix PR 6417: if we're starting a thread and there's no other threadsguenther2010-07-131-2/+3
| | | | | | | running, then we need to start a gc thread...except when this is the very call to start a gc thread! "This works for me" marc@
* Fix PR 6376: restore more thread library state if execve fails,guenther2010-07-133-46/+55
| | | | | | | including the scheduling timer, sigmask, fd nonblocking status, and handling of the signals used by the thread library. ok marc@, additional testing by ajacoutot@

* Use MACHINE_CPU instead of MACHINE_ARCH to pick the correct machine dependentmiod2010-02-031-2/+2
| | | | | | | files or directories when applicable. The inspiration and name of MACHINE_CPU come from NetBSD, although the way to provide it to Makefiles is completely different. ok kettenis@

* Make internal file descriptor handling async-signal safe by eliminatingkurt2009-12-0611-83/+124
| | | | | | the use of spinlocks and malloc. All needed memory is allocated upfront and _thread_kern_sig_defer/undefer() is now used to protect critical sections. okay guenther@
* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-131/+122
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.

* Change libpthread's f*lockfile() routines to stop acting as no-opsguenther2009-10-211-131/+122
| | | | | | | | | for FILEs that don't have real file-descriptors: the fake FILEs used internally by snprintf/asprintf/vfprintf and friends now avoid unnecessary locking by calling the internal __vfprintf() routine directly and we do want to do locking on FILEs created with funopen(). ok kurt@

| | | | | | | | | | | instead of the generic pthread macros since free(3) uses __arc4_getbyte() when freeing small sized allocations and the generic pthread macros call malloc(3). - eliminate passing pointers to a static variable with global scope (rs) for additional code clarity and reduction. - shlib minor bumps for libc and libpthread due to new functions. From andreas@ with some bits from me. okay tedu@ marc@ w/some spot checking from millert@

* _FD_LOCK/UNLOCK() is libpthread specific and not needed for librthread, sokurt2007-06-056-9/+138
| | | | | | | | | | | | | | | | | | | | | | | | | | isolate its usage to libpthread only and replace with generic non-static mutex support in the one place it is needed: - remove _FD_LOCK/UNLOCK from lseek and ftruncate in libc and make the functions weak so that libpthread can override with its own new versions that do the locking. - remove _thread_fd_lock/unlock() weak functions from libc and adjust libpthread for the change. - add generic _thread_mutex_lock/unlock/destroy() weak functions in libc to support non-static mutexes in libc and add libpthread and librthread implementations for them. libc can utilize non-static mutexes via the new _MUTEX_LOCK/UNLOCK/DESTROY() macros. Actually these new macros can support both static and non-static mutexes but currently only using them for non-static. - make opendir/closedir/readdir/readdir_r/seekdir/telldir() thread-safe for both thread libraries by using a non-static mutex in the struct _dirdesc (typedef DIR), utilizing it in the *dir functions and remove remaining and incorrect _FD_LOCK/UNLOCK() use in libc. - add comments to both thread libraries to indicate libc depends on the current implementation of static mutex initialization. suggested by marc@ - major bump libc and libpthread due to function removal, structure change and weak symbol conversions. okay marc@, tedu@

This prevents the child from restoring the file to be blocking upon close() and causing the parent to deadlock when it later attempts to utilize the blocking fd. Corrects the netbeans build failure caused by the jdk forkAndExec() function that replaces the std fd's before execvp(). okay marc@
