(Updated Sept. 6, 2018, 5:35 p.m.)
Review request for mesos, Benjamin Bannier, Benjamin Mahler, and Gastón Kleiman.
Changes
-------
Addressed Benjamin's comment.
Summary (updated)
-----------------
Renamed `Resources::resources` vector and typedef its item type.
Repository: mesos
Description (updated)
-------
Due to the copy-on-write optimization (MESOS-6765), one needs to
check the `use_count` of `Resource_` before mutating. Currently,
there is no mechanism to enforce this. As a short-term mitigation
measure, we rename `resources` to
`resourcesNoMutationWithoutExclusiveOwnership` and typedef its item
type to `Resource_UnSafe`
to alert people about obtaining an exclusive ownership before mutating
the `Resource_` objects.

Fix it, then Ship it!
Also, can you link this with a ticket for following up on the copy-on-write type change?
src/common/resources.cpp
Lines 1641-1659 (original), 1655-1677 (patched)
<https://reviews.apache.org/r/68639/#comment293015>
Shouldn't these be `const Resource_Unsafe&`? Ditto for the other file.
