It should be reasonably easy for me to add this functionality. The code
is in kinda a mess right now, since I'm integrating it with HTML UI, but
I'll get to it in the next few days, most likely.
You will actully find that often, if you insert a file at HTL=25 on the
current node, it can be DNF at HTL=25 *on the same node* if you fetch
remotely ;). This is what I learned from having verification code.
(actully, CofE had already pointed this out to me ages ago, but
nonetheless it was surprising to see that it wasn't an exaggeration)
Reinserting even from the same node actully achieves the same
thing. Consider this:
The fishtools loop goes something like this -> try to retrieve file, if
failed, insert file and try and retrieve again, repeat.
On any given insert, it will fail to retrieve it about 50% of the
time. But that's not the interesting part.
The interesting part is that The first day after I started running
fishland with this code base, I had to reinsert 90% of what I'd inserted
the previous day
A week later, it was down to around 50% of the files
At this point, I'm only reinserting about 130 files or so (of almost
500) per day.
This is all on my transient node on my system. Ironically, it seems that
having a permanent node doesn't nessesarily make this better - when I was
trying to run the stream on your :8481 node, I was failing to verify about
75% of the time. So it's not just communication between two nodes that's
the problem.
Of course, throwing 30 threads at it might not have helped me there
;). But, paradoxically, throwing threads at freenet seems to be the only
way to make things work :-p.
