--------------------------------------
Summary: Memory leak caused by an infinite chain of futures in
`UriDiskProfileAdaptor`.
Key: MESOS-9803
URL: https://issues.apache.org/jira/browse/MESOS-9803
Project: Mesos
Issue Type: Bug
Components: storage
Affects Versions: 1.8.0, 1.7.1, 1.7.0, 1.6.2, 1.6.1, 1.5.3, 1.5.2
Reporter: Chun-Hung Hsiao
Assignee: Chun-Hung Hsiao
Before MESOS-8906, {{UriDiskProfileAdaptor}} only update its promise for
watchers if the polled profile matrix becomes larger in size, and this prevents
the following code in the {{watch}} function from creating an infinite chain of
futures when the profile matrix keeps the same:
https://github.com/apache/mesos/blob/fa410f2fb8efb988590f4da2d4cfffbb2ce70637/src/resource_provider/storage/uri_disk_profile_adaptor.cpp#L159-L160
However, the patch of MESOS-8906 removes the size check in the {{notify}}
function to allow profile selectors to be updated. As a result, once the watch
function is called, the returned future will be chained with a new promise
every time a poll is made, hence creating a memory leak.
