2000-05-06 Kaz Kylheku * internals.h: New thread manager request type, REQ_KICK. * join.c (pthread_exit): main thread now calls exit() instead of _exit() in order to proper process cleanup. * manager.c (__pthread_manager): Do not terminate manager after unblocking main thread; wait for main thread's REQ_PROCESS_EXIT request instead. Also, added REQ_KICK case to handle new request; this just does nothing. * manager.c (pthread_exited): Do not terminate manager after unblocking main thread. * manager.c (__pthread_manager_sighandler): If the main thread is waiting for all other threads to die, send a REQ_KICK into the thread manager request pipe to get it to clean out the threads and unblock the main thread as soon as possible. This fixes the 2000 millisecond hang on shutdown bug. * Examples/ex7.c: New file, tests shutdown behavior when all threads including the main one call pthread_exit(), or implicitly do so. * Makefile (tests): Add ex7. 2000-05-05 Andreas Jaeger * sysdeps/unix/sysv/linux/i386/getcpuclockid.c (pthread_getcpuclockid): Correct test for ourselves. 2000-05-05 Ulrich Drepper * internals.h (struct _pthread_descr_struct): Reorganization.
