Ben Aitchison commented on TS-2469:
-----------------------------------
on my system libssl is being linked against. libreadline and libssl are
actually incompatible license wise to link to both. so if keeping readline
support a check would have to be made that openssl isn't also being linked
against at a minimum

> traffic_shell links against libreadline which is gpl licensed
> -------------------------------------------------------------

> Key: TS-2469
> URL: https://issues.apache.org/jira/browse/TS-2469
> Project: Traffic Server
> Issue Type: Bug
> Reporter: Ben Aitchison
> Assignee: Zhao Yongming
> Priority: Minor
> Labels: traffic_shell
> Fix For: 4.2.0
>
> Attachments: removereadline.txt
>
>
> libreadline is gpl licensed which is infectious. libedit is a free
> alternative, and is already supported in the configure scripts so libreadline
> support should be removed.
> it seems traffic_shell is the only thing using libreadline/libedit currently.
