i found cocos2d-x 3.0 beta2 __Array has a bug.

cocos2d-x C++
#1

__Array* __Array::createWithContentsOfFile(const std::string& fileName)
{
__Array* ret = __Array::createWithContentsOfFileThreadSafe(fileName);
if (ret != nullptr)
{
// 2. this call ret->autorelease() again. !!!
ret->autorelease();
}
return ret;
}

__Array* __Array::createWithContentsOfFileThreadSafe(const std::string& fileName)
{
ValueVector arr = FileUtils::getInstance()->getValueVectorFromFile(fileName);

// 1. this call ret->autorelease()   !!!!!!!!!!!!!!!!!!!!!!!!!!!
__Array* ret = __Array::createWithCapacity(static_cast<int>(arr.size()));

for(const auto &value : arr) {
    ret->addObject(__String::create(value.asString()));
}

return ret;

}

And it’s not thread safe.
because put __CCArray obj in PoolManager.

#2

Thanks for your feedback.
All engine codes are not thread safe.
And __Array is used for compatibility, please use cocos2d::Vector<> instead.

#3

@zhangxm cocos2d::Vector<> faster than __Array?
