Title: Gui bug in shared files wnd and maybe bug of chunk selection
Post by: myth on July 21, 2009, 03:22:19 AM
Ok, the screen shot tells everything...
For the GUI thing i know it won't be fixed until the secret thing, and it's not important ;)

But the other thing is strange, are the other clients asking the same chunks?
So maybe we should implement SCS (selective chunk sharing), or HOS (hide over share)...

I never liked hiding chunks features,

falsifying availability (hiding over-shared chunks) is a bad thing IMO.

maybe something more subtle like ICS (http://wiki.emule-web.de/index.php/Intelligent_chunk_selection) (if its not already)

btw, SCS needs HOS to work.

I have argued a loooot of times against SCS/HOS/any other form of chunk sharing. And so far 100% of the people have been convinced, so take it as a no.

Ok....I can release anyway, but with a feature like this the uploaded data is spreaded more effective!

Are you sure?

Take the following example: You are the sole releaser of a file. 20 people download the first chunk, so you decide not to share it anymore. For whatever reason (file completed and taken out of share, just going offline,...) these 20 people disappear.

Compare the perspective:
- You know that 20 people downloaded this chunk from you. You assume, but don't know, that these 20 people will upload this part of the file and stop sharing this part.
- A downloaded get's the available parts. He knows exactly what chunks are currently available and can make a decision to download a chuck based on these facts.

The downloader has better information. And if you lie to him (by hiding chunks), he can't make good decisions anymore. In the worst case, he sees that the file is not 100% available and decides to stop downloading.

Iirc it's the uploader that decides which chunk he uploads. The downloading client just tells him which parts he has/needs, and the uploader gives him one he's missing. So the uploader should look how aviable a chunk is, and then give him the most rare one. Nevertheless he needs correct information, too, so hiding is still bad.

Nope. Downloader gets a slot and asks for whatever he wants. As long as it's there he gets it.
