Rails&Couchbase - 内存泄漏

Question

我有以下测试代码:

def loop_bucket_gets
    bucket = Couchbase::Bucket.new({:node_list => ['xxx.xxx.xxx.xxx:8091', 'yyy.yyy.yyy.yyy:8091'],
                                    :bucket => 'Foo',
                                    :pool => 'default',
                                    :expires_in => 1.day,
                                    :default_format => :marshal,
                                    :key_prefix => '_foo'
                                   })

    i = 0
    loop do
      begin
        i += 1
        bucket.get "ABC#{i}"
      rescue ::Couchbase::Error::Base => e
        nil
      end
    end
  end

当我在rails控制台中执行该方法时,内存泄漏.

我正在使用:

• couchbase 1.3.10 gem
• libcouchbase 2.4.3

有任何想法吗？

您的循环中没有终止条件，因此它将永远运行并导致您提到的内存问题。您应该在循环中添加相关break条件并测试它是否可以解决问题。

def loop_bucket_gets
    bucket = Couchbase::Bucket.new({:node_list => ['xxx.xxx.xxx.xxx:8091', 'yyy.yyy.yyy.yyy:8091'],
                                    :bucket => 'Foo',
                                    :pool => 'default',
                                    :expires_in => 1.day,
                                    :default_format => :marshal,
                                    :key_prefix => '_foo'
                                   })

    i = 0
    loop do
      begin
        i += 1
        bucket.get "ABC#{i}"
        break if YOUR_TERMINATING_CONDITION
      rescue ::Couchbase::Error::Base => e
        nil
      end
    end
  end
