The `Resources::parse()` seems similar as here.
The original code returns a `Resources` which contains individual `Resource` objects, which removes any empty `Resource` objects (https://github.com/apache/mesos/blob/master/src/common/resources.cpp#L1610). Since we need to know of empty `Resource` objects for this patch, we actually accumulate the `Resource` objects in a `vector<Resource>` (which will contain any empty `Resource` object) which is used when disk resources are present (to check for scalar value of 0 for the auto detection logic). But for the rest of the resources, we do a `Resources resources = parsed.get();` which implicitly converts a `vector<Resource>` to `Resources` which removes the empty `Resource` objects. > On Sept. 19, 2016, 6 a.m., Guangya Liu wrote: > > include/mesos/resources.hpp, line 200 > > <https://reviews.apache.org/r/51999/diff/1/?file=1501128#file1501128line200> > > > > A unit test is needed for this.
