Marco Massenzio updated MESOS-2766:
-----------------------------------
Summary: Add validation behavior to FlagsBase (was: Add to FlagsBase the
default --help behavior)
> Add validation behavior to FlagsBase
> ------------------------------------
>
> Key: MESOS-2766
> URL: https://issues.apache.org/jira/browse/MESOS-2766
> Project: Mesos
> Issue Type: Bug
> Components: stout
> Reporter: Marco Massenzio
> Assignee: Anand Mazumdar
> Priority: Minor
> Labels: tech-debt
>
> In every "launcher" file (ie, those containing some variation on {{main()}})
> there is a minor variation on:
> {code}
> if (flags.help) {
> cout << flags.usage() << endl;
> // arguably this is not an error: the user asked for help,
> // and she got it: // the program execution ought to be
> // considered successful.
> return EXIT_SUCCESS;
> }
> {code}
> As this is default behavior, and we've added support for the {{--help}} flag
> in the {{FlagsBase}} class, we should add this too there and remove it from
> everywhere else.
> This follows the DRY principle.
