I found one major bug which needs to be fixed as soon as possible. The
rwlocks have never worked actually!?!
If something will make owfs more stable, it's probably by fixing this
bug. Strange that nobody have seen this before.
void my_rwlock_init(my_rwlock_t * my_rwlock)
{
_MUTEX_INIT(my_rwlock->protect_reader_count);
sem_init(&(my_rwlock->allow_readers), 0, 1);
sem_init(&(my_rwlock->no_processes), 0, 1);
my_rwlock->reader_count = 1; // This should be initiated to 0! (we
don't have any readers at startup)
}
Changing the reader_count to 0 will probably result into several
dead-locks, so I haven't changed it yet.
Write-locks will ALWAYS be allowed, even if there are several read-locks
active. Look in the example below:
my_rwlock_read_lock(rwlock);
my_rwlock_read_lock(rwlock);
my_rwlock_read_lock(rwlock);
my_rwlock_write_lock(rwlock);
print("this will be printed!\n");
Paul, do you want to look at this?
