Benjamin Bannier created MESOS-6428:
---------------------------------------
Summary: Mesos containerizer helper function signalSafeWriteStatus
is not AS-Safe
Key: MESOS-6428
URL: https://issues.apache.org/jira/browse/MESOS-6428
Project: Mesos
Issue Type: Bug
Components: containerization
Affects Versions: 1.1.0
Reporter: Benjamin Bannier
In {{src/slave/containerizer/mesos/launch.cpp}} a helper function
{{signalSafeWriteStatus}} is defined. Its name seems to suggest that this
function is safe to call in e.g., signal handlers, and it is used in this
file's {{signalHandler}} for exactly that purpose.
Currently this function is not AS-Safe since it e.g., allocates memory via
construction of {{string}} instances, and might destructively modify {{errno}}.
We should clean up this function to be in fact AS-Safe.
