commit 482257a9f46ecab4f888af46cd514d29d7cfd980
Author: Joseph Wu <[email protected]>
Date: Wed Jun 29 18:20:41 2016 -0700
Added test-only function for retrieving link sockets from libprocess.
This can be used in a test to "break" a socket without libprocess's
explicit knowledge. For example, we can disable transmission on a
persistent link. The next message sent over that link will be dropped.

commit 3ae62e27ecb83da36849f6528b997d2087d330f2
Author: Joseph Wu <[email protected]>
Date: Wed Jun 29 18:20:43 2016 -0700
Added tests for libprocess linking and unlinking behavior.
Adds tests which exercise "link" semantics against remote processes.
This includes detection of `ExitedEvents` when the process exits
as well as mixing "link" semantics.
Includes a test case that emulates the failure observed in MESOS-5576.

commit 414f937f270f1aadfe239d61a40ba88d5f2f0501
Date: Wed Jun 29 18:20:44 2016 -0700
Added "relink" semantics to ProcessBase::link.
The `RemoteConnection:RECONNECT` option for `ProcessBase::link` will
force the `SocketManager` to create a new socket if a persistent link
already exists.

> Consider adding `relink` functionality to libprocess
> ----------------------------------------------------
>
> Key: MESOS-5740
> URL: https://issues.apache.org/jira/browse/MESOS-5740
> Project: Mesos
> Issue Type: Improvement
> Components: libprocess
> Reporter: Joseph Wu
> Assignee: Joseph Wu
> Labels: libprocess, mesosphere
> Fix For: 0.28.3, 1.0.0
>
>
> Currently we don't have the {{relink}} functionality in libprocess. i.e. A
> way to create a new persistent connection between actors, even if a
> connection already exists.
> This can benefit us in a couple of ways:
> - The application may have more information on the state of a connection than
> libprocess does, as libprocess only checks if the connection is alive or not.
> For example, a linkee may accept a connection, then fork, pass the
> connection to a child, and subsequently exit. As the connection is still
> active, libprocess may not detect the exit.
> - Sometimes, the {{ExitedEvent}} might be delayed or might be dropped due to
> the remote instance being unavailable (e.g., partition, network
> intermediaries not sending RST's etc).
