-------------------------------------

             Summary: Using multiple services simultaneously is not thread-safe.
                 Key: THRIFT-4384
                 URL: https://issues.apache.org/jira/browse/THRIFT-4384
             Project: Thrift
          Issue Type: Bug
          Components: C++ - Compiler, C++ - Library
    Affects Versions: 0.10.0
         Environment: Should affect all platforms but has been noticed first on Windows, x86_64.
            Reporter: Michael Eiler
            Priority: Critical
             Fix For: 0.11.0, 0.10.0


I'm using the generated *ServiceConcurrentClient classes. They should allow me to call multiple functions at the same time.

The issue as that the ::apache::thrift::async::TConcurrentClientSyncInfo class is a member of the generated service. If I have a project with multiple services sharing the same connection (protocol) with each other, the services will not be mutually excluded from reading on the same socket. 

I did a small test with patching the generated code and injecting the same instance of TConcurrentClientSyncInfo into all my services and everything was fine.

Question: Do you need a small project to reproduce this or is it obvious enough? Just check out any generated code and you will see that the TConcurrentClientSyncInfo is not shared between different services.
