示例1: double_size
bool double_size(bool serial_thread) {
printf("\nWarning: Specified hash size insufficent - attempting to double hash size...");
if(serial_thread) {// Allocate new array for size doubling
try {
new_ary_ = new array(ary_->size() * 2, ary_->key_len(), ary_->val_len(),
ary_->max_reprobe(), ary_->reprobes());
} catch(typename array::ErrorAllocation e) {
new_ary_ = 0;
}
}
size_thid_ = 0;
size_barrier_.wait();
array* my_ary = *(array* volatile*)&new_ary_;
if(!my_ary) // Allocation failed
return false;
// Copy data from old to new
uint16_t id = atomic_t::fetch_add(&size_thid_, (uint16_t)1);
// Why doesn't the following work? Seems like a bug to
// me. Equivalent call works in test_large_hash_array. Or am I
// missing something?
// eager_iterator it = ary_->iterator_slice<eager_iterator>(id, nb_threads_);
eager_iterator it = ary_->eager_slice(id, nb_threads_);
while(it.next())
my_ary->add(it.key(), it.val());
size_barrier_.wait();
if(serial_thread) { // Set new ary to be current and free old
delete ary_;
ary_ = new_ary_;
}
// Done. Last sync point
size_barrier_.wait();
printf(" success!\n");
return true;
}
