Subj : hpt bug: Missing seen+by's in echomails send to same zone links

Hi Developers,

I'm receiving some dupes that shouldn't happen. For echomail messages that originate or go through systems using hpt 1.9, which have -sbkeepall in their config set.


For instance here's a routing diagram of what I see for messages generated on 3:770/1 in the STATS area:

  +----------+   A    +-----------+
  + 3:770/1  |------->| 3:712/848 |
  +----------+        +-----------+
       |                   |
     B |   +-----------+   | C
       +-->| 2:280/464 |<--+
           +-----------+

A: Only Z3 downlinks of 3:770/1 in the seenby's
B: All downlinks (in all zones) of 3:770/1 in the seenby's
C: Unnecessary dupes received through 3:712/848, because my node should be in the seen+by's of the message received by 3:712/848 from 3:770/1.


An example for today:

 From : 3:770/1             2024-01-31 23:59:16
 To   : All
 Subj : Daily Areas Summary
@MSGID: 3:770/1 65ba2805

Has the following seen+by's and path when received directly from 3:770/1 by my system:

SEEN+BY: 218/840 220/70 226/17 267/800 280/464 712/848 770/1 100 330 340
SEEN+BY: 772/220 230
PATH: 770/1

And these when received through 3:712/848 as dupe:

SEEN+BY: 229/426 280/464 301/1 633/267 712/620 848 770/1 100 330 340 772/220
SEEN+BY: 772/230
PATH: 770/1 712/848

Notice that all the Z1 downlinks of 3:770/1 (218/840 220/70 226/17 267/800) present in the direct message, are missing from the seen+by's in the message that is received as dupe from 3:712/848.

I have confirmation it's the originating hpt system where this is happening, and there is no seen+by stripping taking place on the system in between.

3:770/1 Seems to be using hpt/lnx 1.9 2022-07-03

I've also confirmed the same thing happening on another system using hpt/lnx 1.9 2023-02-24.


Bye, Wilfred.
