52coder opened a new issue, #1870: URL: https://github.com/apache/incubator-brpc/issues/1870
**Describe the bug (描述bug)** 基于example中的例子验证可选熔断(根据失败率） 原始代码：https://github.com/52coder/incubator-brpc/tree/master/example/asynchronous_echo_c%2B%2B client.cpp代码修改点： https://github.com/52coder/incubator-brpc/blob/master/example/asynchronous_echo_c%2B%2B/client.cpp#L65后添加： options.enable_circuit_breaker = true; L30行修改为rr : DEFINE_string(load_balancer, "rr", "The algorithm for load balancing"); server.cpp中未改动，先编译出来echo_server,然后在https://github.com/52coder/incubator-brpc/blob/master/example/asynchronous_echo_c%2B%2B/server.cpp#L63前面增加如下代码： cntl->SetFailed(brpc::EREQUEST, "Fail to parse request");然后编译出二进制echo_server_fail 这里的想法是先构造一个100%失败的server触发熔断。 **To Reproduce (复现方法)** 验证方法，三个终端下分别执行 ./echo_server --port=8001 ./echo_server --port=8002 ./echo_server_fail --port=8003 client端运行： ./echo_client --server="list://192.168.49.1:8001,192.168.49.1:8002,192.168.49.1:8003" **Expected behavior (期望行为)** 期望行为是由于client端开启了熔断，其中一个server一直返回失败，所以应该会触发熔断才对，实际结果是跑了一晚上，一直出错的那个server并未摘除 ` I0803 00:26:21.137101 1872894 client.cpp:45] Received response from 192.168.49.1:8002: hello world (attached=bar) latency=603us I0803 00:26:22.137842 1872886 client.cpp:45] Received response from 192.168.49.1:8003: hello world (attached=bar) latency=734us W0803 00:26:23.138861 1872894 client.cpp:42] Fail to send EchoRequest, [E1003][127.0.1.1:8001][E1003]Fail to parse request I0803 00:26:24.139042 1872886 client.cpp:45] Received response from 192.168.49.1:8002: hello world (attached=bar) latency=590us I0803 00:26:25.139412 1872894 client.cpp:45] Received response from 192.168.49.1:8003: hello world (attached=bar) latency=639us W0803 00:26:26.140028 1872886 client.cpp:42] Fail to send EchoRequest, [E1003][127.0.1.1:8001][E1003]Fail to parse request I0803 00:26:27.140468 1872894 client.cpp:45] Received response from 192.168.49.1:8002: hello world (attached=bar) latency=733us I0803 00:26:28.141491 1872886 client.cpp:45] Received response from 192.168.49.1:8003: hello world (attached=bar) latency=739us W0803 00:26:29.142124 1872894 client.cpp:42] Fail to send EchoRequest, [E1003][127.0.1.1:8001][E1003]Fail to parse request I0803 00:26:30.142181 1872886 client.cpp:45] Received response from 192.168.49.1:8002: hello world (attached=bar) latency=484us I0803 00:26:31.142817 1872894 client.cpp:45] Received response from 192.168.49.1:8003: hello world (attached=bar) latency=737us W0803 00:26:32.143875 1872886 client.cpp:42] Fail to send EchoRequest, [E1003][127.0.1.1:8001][E1003]Fail to parse request I0803 00:26:33.144834 1872894 client.cpp:45] Received response from 192.168.49.1:8002: hello world (attached=bar) latency=748us I0803 00:26:34.145134 1872886 client.cpp:45] Received response from 192.168.49.1:8003: hello world (attached=bar) latency=676us W0803 00:26:35.145437 1872894 client.cpp:42] Fail to send EchoRequest, [E1003][127.0.1.1:8001][E1003]Fail to parse request I0803 00:26:36.145931 1872886 client.cpp:45] Received response from 192.168.49.1:8002: hello world (attached=bar) latency=739us ` **Versions (各种版本)** OS: Compiler: brpc: protobuf: **Additional context/screenshots (更多上下文/截图)** -- This is an automated message from the Apache Git Service.
