目前的rocketmq-client-cpp包含以下俩个问题

1. ERROR: GetTransport of:xxx get timed_mutex timeout 解决办法 rocketmq-client-cpp#456
2. consumer stuck in rebalance and doesn't consume messsages rocketmq-client-cpp#293 (comment)

debian系:rocketmq-client-cpp-2.2.1.amd64.deb.zip

redhat系:rocketmq-client-cpp-2.2.1-centos.x86_64.rpm.zip

所以我对官方代码进行了重新编译,主要两处变更:

1. 使用gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04) 编译
2. 魔改:为了最小化rebalance后的重复消费影响,改了源码中DefaultPushConsumer批量拉取消息的数量,改为1了
