@aaron-ai thanks for your interest in contributing this awesome feature! I'm going to be honest in saying that we cannot accept an 8K line PR with no prior notice and no plan for reviewing. Do you have any maintainers in mind who would be willing to sponsor reviewing this PR and seeing that it get merged? Thank you.

aaron-ai · 2020-01-06T09:25:01Z

@mattklein123 Thanks for your feedback first! This pull request does look too big at first sight, but more than half code of lines are test cases to meet 100% test coverages goal required here. The main source parts are self-contained and generally feature-implement-purpose. Once understanding core concepts of Apache RocketMQ, reviewing this PR will not be as challenging as initial thought.

CODEOWNERS

@aaron-ai There must be a maintainer in code owner https://github.com/envoyproxy/envoy/blob/master/EXTENSION_POLICY.md

Thanks @zyfjeff, we are still looking for a maintainer who has the convenience of sponsoring.

@aaron-ai @lizhanhui I don't have the bandwidth right now to do a full review for this and I doubt any of the @envoyproxy/maintainers do either, but they can speak for themselves. However, if @zyfjeff is willing to take point and do a thorough review I'm happy to do a skim afterwords and sponsor. @zyfjeff does that sound OK to you?

@mattklein123
I would be happy to review this, I used to write rocketmq c++ sdk, so I think I can do it

Awesome. Thank you so much! :)

I can help review, but unfortunately I am not a maintainer

Thanks, I'll fix it.

Is it possible to split a separate PR for review?

I do not believe that this code is part of the rocketmq_proxy filter, and this part of the code does not pass review in #8984 .

Let's not depend on rapidjson. See: #4705

I also had the same ideas, 😄

zyfjeff · 2020-01-07T02:14:28Z

source/extensions/filters/network/rocketmq_proxy/active_message.cc

Envoy is now actively trying to get rid of its depends on rapidjson #4705 we should convert to JSON using protobuf

Now replaced with Protobuf.

zyfjeff · 2020-01-07T02:15:51Z

source/extensions/filters/network/rocketmq_proxy/active_message.cc

Redundant code that can be put into a common function for stats statistics.

zyfjeff · 2020-01-10T09:16:37Z

source/extensions/filters/network/rocketmq_proxy/well_known_names.h

Please replace it with the idiom used by the Envoy,

struct RocketmqValues { const std::string CLUSTER_TYPE{xxxx}; }; using RocketmqConstants = ConstSingleton<RocketmqValues>;

Nice catch.

It has been fixed.

zyfjeff · 2020-01-10T09:24:26Z

source/extensions/filters/network/rocketmq_proxy/topic_route.h

please replace std::vector<QueueData>& queueData to std::vector<QueueData>&& queueData

It is not easy to read

std::vector<QueueData> test TopicRouteData tt(test); // The following code is not aware that test has been moved and will continue to use test

But it's much easier to read if you go like this

std::vector<QueueData> test TopicRouteData tt(std::move(test)); // I knew from looking at the code that test had been moved.

OK, let's use the move way.

zyfjeff · 2020-01-10T11:12:29Z

source/extensions/filters/network/rocketmq_proxy/topic_route.h

broker_addrs_(brokerAddrs) Do we need a copy here?

All right. Will use move to avoid copy

zyfjeff · 2020-01-10T12:47:27Z

source/extensions/filters/network/rocketmq_proxy/router/router_impl.h

How do you ensure that the string referenced by target_host_ is always valid?

target_host_ referenced can only be either empty or a valid target host. In case it is empty, host selection is completely subject to the LB. If it is a valid target host address, the request will be routed to it.

Refer to this comment

I mean whether the memory referenced by target_host_ is valid, not the content.

zyfjeff · 2020-01-10T13:23:39Z

source/extensions/filters/network/rocketmq_proxy/conn_manager.cc

sendRequestToUpstream(target_host) -> createFilterChain(target_host); -> connection_manager_.config().createRouter(target_host);

RouterPtr createRouter(absl::string_view target_host) override { return std::make_unique<RouterImpl>(context_.clusterManager(), target_host); } class RouterImpl { private: absl::string_view target_host_; }

Finally, target_host_ in RouterImpl refers to the target_host here, but the target_host here is released when it leaves the scope, resulting an undefined behavior in routerimpl.target_host_ refers to invalid memory.

Ah, I get your point. This is a bug. target_host_ should be of std::string, not string_view.

string_view has been fixed already.

aaron-ai · 2020-03-06T09:19:23Z

@zyfjeff All issues above have been fixed.

zyfjeff · 2020-03-17T12:42:57Z

source/extensions/filters/network/rocketmq_proxy/router/router_impl.cc

remove, Didn't see this variable used

zyfjeff · 2020-03-17T12:50:07Z

source/extensions/filters/network/rocketmq_proxy/router/router_impl.cc

Well, I think you should implement shouldSelectAnotherHost, not hostSelectionRetryCount.

zyfjeff · 2020-03-17T12:54:57Z

source/extensions/filters/network/rocketmq_proxy/router/router_impl.cc

I think that subset should be used to select the endpoint

OK, I will use subset instead.

aaron-ai · 2020-03-24T04:15:34Z

@zyfjeff All issues above have been fixed.

zyfjeff

@aaron-ai good work, I have finished review, I have no issues.

aaron-ai · 2020-03-27T14:55:40Z

All code of rocketmq's proxy have been reviewed by @zyfjeff , are you available to sponsor our extension recently ? @lizan

lizan · 2020-04-03T03:18:54Z

Can you merge master once? I can sponsor meanwhile until someone from Alibaba becomes maintainer, but I don't have enough bandwidth to review this week.

htuch · 2020-04-07T14:53:08Z

Please merge master to pick up #10672. We no longer accept changes to v2 (without explicit exception), so any API modifications should happen in v3. If this PR is adding a new proto, please follow the updated instructions in https://github.com/envoyproxy/envoy/blob/master/api/STYLE.md#adding-an-extension-configuration-to-the-api.

lizan

Can you merge master again to pick 1.14.0 release and then add a release note for 1.15.0?

Hi, @lizan, Release note is added to current.rst and constexpr-issues are fixed.

One more TODO is also inserted, indicating future work that is planned.

aaron-ai · 2020-04-15T13:57:40Z

More docs have been added. A small part of code are not covered by UT, and I will implement them tomorrow.

lizhanhui · 2020-04-21T13:21:36Z

@lizan Unit tests have been supplemented and all issues raised are properly resolved.
