> Key: MESOS-1987
> URL: https://issues.apache.org/jira/browse/MESOS-1987
> Project: Mesos
> Issue Type: Bug
> Reporter: Kapil Arya
> Assignee: Kapil Arya
>
> Currently, the Version class handles strings of the form X.Y.Z only. A recent
> patch (https://reviews.apache.org/r/27115/) allows for strings of the form
> X.Y.Z-* by discarding the "-" along with the rest of the string following it.
> This means that the check `Version("0.20.1") == Version("0.20.1-rc2")` will
> succeed.
> A better fix is to allow arbitrary number of components in the Version string
> and still do the right thing w.r.t. comparisons. To standardize it a bit, we
> can consider Semantic Versioning (http://semver.org/).
> Semantic Versioning allows for strings of the following tagformat:
> <code>
> "MAJOR.MINOR.PATCH-IDENTIFIER[.IDENTIFIER]*"
> </code>
> An IDENTIFIER must comprise only ASCII alphanumerics and hyphen [0-9A-Za-z-].
> One way to implement it in the Version class is to keep a vector of (string)
> identifiers along with major, minor, and patch variable. Another alternative
> is to not have the major, minor, and patch variables and just have a single
> vector of strings.
> The comparison can be tricky. One has to consider the pre-release version,
> etc. as explained in SemVer 2.0.0 RFC.
