[jira] [Created] (MESOS-815) Race condition in
process::ID::generate().
Jie Yu created MESOS-815:
----------------------------
Summary: 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: Jie Yu
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.
