HealthCheckThread is replaced by StartHealthCheck function in socket.cpp, but some of the docs/comments are not modified correspondingly. There are 3 files that HealthCheckThread is involved in:

• test/brpc_socket_unittest.cpp(3 occurrences)
• docs/cn/load_balancing.md(1 occurrence)
• src/brpc/socket.h(1 occurrence)

All sentences with 'HealthCheckThread' should be rewritten to sync with the

Let's support at least reading "b3" header from a single string, most commonly traceid-spanid-1
It would also be nice to support optionally writing this, especially in message providers or others with constrained environments.

Expected behavior

As discussed on openzipkin/b3-propagation#21 and first implemented here: https://github.com/openzipkin/brave/blob/master/brave/src/main/java/bra

When writing a test case with ServerRule or ServerExtension, a user sometimes wants to capture the ServiceRequestContexts:

class MyJUnit5Test {
  static final var serviceContexts =
      new LinkedBlockingQueue<ServiceRequestContext>();

  @RegisterExtension
  static final var server = new ServerExtension() {
    @Override
    protected void configure(ServerBuilder sb) thr

interface TestService{
    bool process(string cmd);
};

The go source code generates by tars2go can't build successfully. The error is:

cannot use _funRet_ (type bool) as type int32 in argument to _os.Write_int32
