-----------------------------
Summary: Master can fail to detect HTTP framework disconnection if
it disconnects very fast
Key: MESOS-8138
URL: https://issues.apache.org/jira/browse/MESOS-8138
Project: Mesos
Issue Type: Bug
Components: HTTP API, master
Reporter: Yan Xu
What we've observed is that if the framework disconnects before the master
actor processes the request, the master would [set up an exited
callback|https://github.com/apache/mesos/blob/f26ffcee0a359a644968feca1ec91243401f589a/src/master/master.cpp#L8179]
that never gets triggered.
It looks like it's because when the socket closes and libprocess terminates the
HttpProxy for this socket, [the pipe reader for this proxy is not
set|https://github.com/apache/mesos/blob/f599839bb854c7aff3d610e49f7e5465d7fe9341/3rdparty/libprocess/src/process.cpp#L1515-L1518].
Later when the master [sets up the
callback|https://github.com/apache/mesos/blob/f26ffcee0a359a644968feca1ec91243401f589a/src/master/master.cpp#L8179],
it would be a noop in this regard.
