cygwin : ChangeLog dcrt0.cc fork.cc thread.cc thread.h
Log message:
* dcrt0.cc (child_info_fork::alloc_stack_hard_way): Change sense of
guard test.
Increase size of stack reserved and increase size before the current
stack
pointer. Use pointers when doing arithmetic.
(dll_crt0_1): Initialize exception handler when we notice we're the
child of a
fork from non-main thread.
* fork.cc (frok::parent): Make argument volatile.
(frok::child): Ditto.
(lock_signals): New class.
(lock_pthread): Ditto.
(hold_everhthing): Ditto.
(frok::parent): Move atforkprepare and atforkparent to lock_pthread
class.
(fork): Make ischild boolean. Use hold_everything variable within
limited
scope to set various mutexes in such a way as to avoid deadlocks.
* thread.h (pthread_mutex::tid): New variable, active when debugging for
tracking thread id of owner.
(pthread_mutex::set_owner): Set tid when debugging.
* thread.cc (pthread_mutex::pthread_mutex): Clear tid.
(pthread_mutex::_unlock): Ditto when unlocking.
(pthread_mutex::fixup_after_fork): Set tid to special value after
forking since
owner is unknown.
