--------------------------------
Summary: Libprocess links will not generate an ExitedEvent if the
socket creation fails
Key: MESOS-6246
URL: https://issues.apache.org/jira/browse/MESOS-6246
Project: Mesos
Issue Type: Bug
Components: libprocess
Affects Versions: 1.0.1, 0.28.2, 0.27.3
Reporter: Joseph Wu
Assignee: Joseph Wu
Noticed this while inspecting nearby code for potential races.
Normally, when a libprocess actor (the "linkee") links to a remote process, it
does the following:
1) Create a socket.
2) Connect to the remote process (asynchronous).
3) Check the connection succeeded.
If (2) or (3) fail, the linkee will receive a {{ExitedEvent}}, which indicates
that the link broke. In case (1) fails, there is no {{ExitedEvent}}:
