helloeveroneday opened a new issue #928: span trace信息无法正常传递，麻烦确认tls_bls.rpcz_parent_span用法是否正确 URL: https://github.com/apache/incubator-brpc/issues/928 **Describe the bug (描述bug)** span的trace id在请求时，无法跨服务传递。首次请求时大概率出现。 **To Reproduce (复现方法)** 使用curl请求 brpc http服务A，A收到请求后使用brpc标准同步接口调用B服务。curl请求时带trace id信息。在span.cpp SpanDB::Index函数中新增 trace信息输出，未能正常输出。 **Expected behavior (期望行为)** A服务 B服务均正常获取 trace id。可正常打印trace信息。 **Versions (各种版本)** OS: 16.04.11 Compiler: gcc version 5.4.0 brpc: master protobuf: **Additional context/screenshots (更多上下文/截图)**  **推测的原因**是src/brpc/span.h中tls_bls.rpcz_parent_span用法有问题。 看起来tls_bls正常情况需要同步给bthread中bthread::tls_task_group的current_task()->local_storage。切换bthread后 local_storage同步回tls_bls。 但**span中的 tls_bls.rpcz_parent_span 未见同步给bthread local_storage**。 麻烦确认是否是此原因导致span trace信息无法正常传递。
