Leif Hedstrom commented on TS-3245:
-----------------------------------
As [~amc] points out, maybe we can do this in the core, before calling the init
functions of the plugins. And then avoid having to deal with it in every plugin.
> 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: 6.2.0
>
>
> 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.
