2014-01-22Fix thread destructionRichard Braun
Releasing a thread reference uses a mutex, which means the kernel resources used for synchronization must be available until late during the destruction process.

2013-12-26Implement thread destructionRichard Braun
This change makes libpthread release almost every resource allocated for a thread, including the kernel thread, its send right, its reply port and its stack. This improves resource usage after peaks of activity during which servers can create hundreds or even thousands of threads. To achieve this, the library relies on the recently added thread_terminate_release one-way GNU Mach RPC, which allows threads to release their last resources along with terminating in a single operation. The pthread_exit function unconditionally releases all the resources it can, including other kernel objects (namely the port used for blocking and waking up) and signal states. When releasing the pthread structure, a reference counter is used so that joinable threads remain available. Once the reference counter drops to 0, the pthread structure can be recycled. Thread local storage (TLS) is also recycled since it needs to remain allocated while terminating the thread, as it is there that the reply port is stored. TLS could be released too, after grabbing the reply port name, but it is difficult to make sure no RPC involving a reply port is used afterwards, so the simpler solution of recycling TLS was chosen. * Makefile (libpthread-routines): Replace pt-thread-halt with pt-thread-terminate. * pthread/pt-alloc.c (initialize_pthread): Set reference counter and unconditionally initialize new threads completely. (__pthread_alloc): Remove call to __pthread_thread_halt, update calls to initialize_pthread. * pthread/pt-create.c (__pthread_create_internal): Don't attempt to reuse stacks, handle reference counter, update failure handling. * pthread/pt-dealloc.c: Include bits/pt-atomic.h. (__pthread_dealloc): Make pthread structure available for reuse when reference counter reaches 0. * pthread/pt-detach.c (pthread_detach): Assume the target thread takes care of its own resources and, as a result, simply unreference its pthread struct. * pthread/pt-exit.c (__pthread_exit): Release resources and terminate. * pthread/pt-internal.h (struct __pthread): New `nr_refs' member. (__pthread_alloc): Update description. (__pthread_dealloc): Likewise. (__pthread_thread_dealloc): Likewise. (__pthread_thread_terminate): New declaration. * pthread/pt-join.c (pthread_join): Assume the target thread takes care of its own resources and, as a result, simply unreference its pthread struct. * sysdeps/mach/hurd/pt-sigstate-destroy.c (__pthread_sigstate_destroy): Call _hurd_sigstate_delete. * sysdeps/mach/hurd/pt-sigstate-init.c (__pthread_sigstate_init): Call _hurd_thread_sigstate and _hurd_sigstate_set_global_rcv when appropriate. * sysdeps/mach/hurd/pt-sysdep.c (__pthread_create_internal): Prevent the library from releasing the stack of the main thread. * sysdeps/mach/hurd/pt-sysdep.h (PTHREAD_SYSDEP_MEMBERS): Remove `have_kernel_resources' from the list of sysdep members. * sysdeps/mach/pt-thread-alloc.c (__pthread_thread_alloc): Update thread allocation. * sysdeps/mach/pt-thread-dealloc.c (__pthread_thread_dealloc): Update description. * sysdeps/mach/pt-thread-halt.c: Remove file. * sysdeps/mach/pt-thread-start.c (__pthread_thread_start): Fix the conditions under which a thread should actually be started. * sysdeps/mach/pt-thread-terminate.c: New file.
2013-10-24Really use user-provided stackSamuel Thibault

(__pthread_alloc): Deallocate TLS of to-be-reused `new` thread. * pthread/pt-create.c (__pthread_create_internal): Reset `tcb` field to NULL after deallocation. * pthread/pt-exit.c (__pthread_exit): Do not deallocate TLS.

2012-09-15pthread_create: turn ENOMEM to EAGAINPino Toscano
ENOMEM can be returned if some malloc fail, but it is not a valid POSIX error number for pthread_create; thus turn it to EAGAIN. * pthread/pt-create.c (pthread_create): Turn ENOMEM to EAGAIN.

Move code which deallocates kernel resources from here ... * sysdeps/mach/pt-thread-dealloc.c (__pthread_thread_dealloc): ...to here. * pthread/pt-create.c (__pthread_create_internal): Call __pthread_thread_dealloc on failure. * pthread/pt-exit.c (pthread_exit): Call __pthread_thread_dealloc. * sysdeps/mach/pt-thread-alloc.c (create_wakeupmsg): Call __mach_port_destroy to deallocate the receive right. __mach_port_deallocate won't do it. * pthread/pt-detach.c (pthread_detach): Don't call __pthread_thread_halt a second time. * sysdeps/mach/hurd/pt-sysdep.c (_cthread_init_routine): Fix declaration. (init_routine): Update declaration and remove gratuitous cast.
