Hi. I opened PR #696 under a new branch with a new patch based on the
sample code provided by @jpeach. I had to re-base this branch on my local
repository with master due to all of the intervening patches, but then I had
difficulty pushing it into my GitHub fork. I didn't want to mess around with
this branch in my fork in case it deleted these informative comments.
> 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
> Affects Versions: 5.1.1
> Reporter: Sudheer Vinukonda
> Priority: Minor
> Labels: newbie
> Fix For: sometime
>
>
> When multiple plugins that use getopt are chained, it doesn't work correctly
> for the subsequent plugins after the first plugin. [[email protected]] 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.
