Benjamin Mahler reassigned MESOS-815:
-------------------------------------
Assignee: Benjamin Mahler (was: Jie Yu)
> Race condition in process::ID::generate().
> ------------------------------------------
>
> Key: MESOS-815
> URL: https://issues.apache.org/jira/browse/MESOS-815
> Project: Mesos
> Issue Type: Bug
> Components: c++ api
> Environment: Linux gcc-4.2.1
> Reporter: Jie Yu
> Assignee: Benjamin Mahler
>
> string generate(const string& prefix)
> {
> static map<string, int> prefixes;
> stringstream out;
> out << __sync_add_and_fetch(&prefixes[prefix], 1);
> return prefix + "(" + out.str() + ")";
> }
> This function could be called from multiple threads and the std::map
> 'prefixes' is not protected by lock, leading to a race condition. This causes
> framework to segfault.
