Jon Siwek commented on BIT-1259:

Yes, the change from BIT-1246 could cause the same data to be delivered twice in some cases, so your sample was triggering http_message_done at an earlier point than it should have (the content-length was being hit sooner due to the duplicate data sent for HTTP analysis).  Should be fixed now in git/master.

>             Project: Bro Issue Tracker
>          Issue Type: Problem
>          Components: Bro
>    Affects Versions: git/master
>         Environment: CentOS 6
>            Reporter: Jimmy Jones
>             Fix For: 2.4
>         Attachments: debug.bro, sample-pipeline8b.pcap
> Bro 2.3-136 and 2.3-178 give different values for connection$resp$size, possibly as a result of BIT-1246. From the documentation https://www.bro.org/sphinx-git/scripts/base/init-bare.bro.html#type-endpoint I'd expect it to be unaffected by missing packets, but the later version appears to be.
