             Summary: getopt doesn't work correctly when used in plugin chaining
                 Key: TS-3245
                 URL: https://issues.apache.org/jira/browse/TS-3245
             Project: Traffic Server
          Issue Type: Improvement
          Components: Plugins
            Reporter: Sudheer Vinukonda


When multiple plugins that use getopt are chained, it doesn't work correctly for the subsequent plugins after the first plugin. [~jpeach@apache.org] and [~zwoop] suggested that the getopt globals need to be reset (example, {{optind = opterr = optopt = 0}}) before using it and would be better to do it in the core during plugin loading to keep it simple/transparent from plugin development. 

Note that, if a plugin itself uses getopt multiple times on different argv's, it would have to reset the globals between them.
