Joseph Wu created MESOS-4535:
--------------------------------
Summary: Logrotate ContainerLogger may not handle FD ownership
correctly
Key: MESOS-4535
URL: https://issues.apache.org/jira/browse/MESOS-4535
Project: Mesos
Issue Type: Bug
Components: modules
Reporter: Joseph Wu
Assignee: Joseph Wu
Priority: Blocker
One of the patches for [MESOS-4136] introduced the {{FDType::OWNED}} enum for
{{Subprocess::IO::FD}}.
The way the logrotate module uses this is slightly incorrect:
# The module starts a subprocess with an output {{Subprocess::PIPE()}}.
# That pipe's FD is passed into another subprocess via
{{Subprocess::IO::FD(pipe, IO::OWNED)}}.
# When the second subprocess starts, the pipe's FD is closed in the parent.
# When the first subprocess terminates, the existing code will try to close the
pipe again. This effectively closes a random FD.
