32 位 Linux 上的节点 0.10.24 + mongo 节点驱动程序 1.3.23
我在这里的回调永远不会被执行。
console.log(record_collection);
record_collection.find({}, function (error, cursor) {
console.log("record_collection.find() returned");
if (error) {
console.log(error);
callback(error);
}
else {
console.log("calling toArray with cursor");
cursor.toArray(function(error, docs){
console.log("cursor.toArray() returned");
if (error) {
console.log(error);
callback(error);
}
else {
callback(null, docs);
}
});
}
});
本节的输出如下所示：

record_collection.find() returned
calling toArray with cursor
看起来集合的第一个 console.log() 没有完成。但出现了其他痕迹。为什么不执行回调？为什么我没有看到“cursor.toArray() 返回”？
当我搬到新服务器时，这停止了工作。旧服务器运行节点 0.10.13 和 mongodb 1.2.13。
