James E. King III commented on THRIFT-4384: ------------------------------------------- I am working on this, I got the codegen working and I have updated the cmake build to use the new code by running a StressTest with --client-type=concurrent. This will exercise (and would have caught) the issue/fix. > Using a concurrent client with cpp async is not 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, 0.11.0, 0.12.0 > Environment: Should affect all platforms but has been noticed first > on Windows, x86_64. > Reporter: Michael Eiler > Priority: Major > Labels: async > Time Spent: 10m > Remaining Estimate: 0h > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
