using TLS cause process hangs in Watcher constructor about etcd-cpp-apiv3 HOT 7 OPEN

You mean, after successfully creating a set of watchers, they works and expected and the next new watcher hangs in its constructor?

from etcd-cpp-apiv3.

I'm not sure what happens in the details, but could you please try to create every new watcher with a new client?

Creating watcher from established client will reuse the underlying gRPC channel.

It never should hang, though. Could you please provide me a simplified test program to reproduce?

Our code snippet are as below:

// read {url, ca, cert, key} from config
auto pEtcd = new etcd::Client(url, ca, cert, key, "round_robin");
//
// if we use insecure etcd::Client, it will not hang
// auto pEtcd = new etcd::Client(url, "round_robin");
//
// some code, the belowing code run in multi threads, and pEtcd is shared
// in these multi threads
//
while (SomeCondition) {
   std::atomic<bool> done{false};
   etcd::Response response;
   auto callback = [&](etcd::Response&& resp_task) {
      response = std::move(resp_task);
      done.store(true);
   };
   int from_index = 0;
   std::string watch_key = DifferentOnEachLoop();
   // here, after several successful construction, later construction hang
   etcd::Watcher watcher(*pEtcd, watch_key, from_index, callback);
   //
   // some code
   //
  pEtcd->rm(watch_key);
}

I can reproduce the issue, but have no idea about what's going wrong, and don't have enough time to investigate currently.

To workaround the issue, you could issue a new client everything you creating a watcher.

Yes, we have worked around this issue, we are also expecting the fix.

ca, cert, key 可以直接使用k8s给etcd生成的密钥文件吗
