Deluge Forum

Hey,

I've been a very happy deluge user for a couple years now, but will be switching to using rtorrent in the next week as deluge has just been banned from a couple private post-oink trackers. This was obviously very surprising. One of the claims for the banning is such:

"After performing an analysis on our swarms, we found that over 4088 downloads, deluge downloaded, on average, 15.4% more data than the size of the torrent."

andar posted in a discussion on a tracker site that "The issue with Deluge (actually it's an issue with libtorrent) has been fixed and will be in the next version of libtorrent 0.14.9 or 0.15. The problem was due to some old workarounds to accommodate buggy Bitcomet peers and it has been removed."

Is there a larger story here? What kind of workarounds make deluge download 15% more data than other clients? Are certain site admins aware of this fix being pushed out? etc. etc.

Deluge is great and I hope to keep using it in the future!

Thanks!!!!

Same issue/question here. I will be switching over the weekend, but Deluge is a wonderfully user-friendly client and I hope its redundant downloading problems get fixed so it gets whitelisted again in the future.

As much as we care that your download stats are reported correctly its more important for us to be able to determine legitimate upload of other users. If you download the same pieces from 2 peers both of those report upload, we track this but we also know that the file is only Xmegs. We then have 2 or 3 or 10 peers each reporting a combined total of X*1.15megs. Do you not see this as an issue. We are not a public tracker, we enforce ratio rules and as such we do have to track prevent and disable cheaters. You are making innocent users appear as cheaters because you use a broken client.

The fact that 1.3% of you feel you have an advantage using deluge is far less important than the 100% of users that are impacted by your faulty client.

Same dilemma here. Is there a response for the developers on this issue? This 15.4% figure that these sysops's are throwing around that it over downloads is a completely blow out of proportion, yet I have noticed it downloads more than actual torrent; never more than less than 1% of the actual torrent size although. Nothing that made me want to open a ticket

If there are plans to move deluge to a different backend, such as the libtorrent that rtorrent uses, I would rather just wait for a new version of deluge. 1.3.0 maybe?

Edit:
After searching the forum, I have found that this issue has been brought up. Though no clear message as to if it will be addressed

Considering the private trackers in question, no doubt Deluge's user base will come crashing down by next Monday.

I've heard that the "fix" is to simply not report the extra downloaded amount. Obviously this is not a fix and simply a workaround that breaks the bittorrent spec. I understand the issue is in libtorrent and not deluge. Does the deluge team plan to sort this out in an acceptable way? Is changing to the same libtorrent that rtorrent uses a possibility? Or are you guys just waiting on the current libtorrent team to properly fix it? I'm just wondering the status on this bug so I know whether or not I should hold my breath for a fix heh.

Download reporting has been a know issue for a while but I had just ignored it. I have to move clients too, so I am back to transmission.

Still keeping deluge for other trackers. The auto extractor plugin and auto pickup plugin will be sorely missed!

Not entirely true.

From the libtorrent (rasterbar) developer:

&downloaded= is now defined as to exclude failed and redundant bytes, bringing it in line with the behavior of other major clients.

Previously, when Deluge downloaded some additional material, it reported having done so. Other clients do not, and now Deluge will not. So, while technically your statement is accurate, it's not as if Deluge is now lying in a unique way... apparently all clients do.

Also:

The end-game mode is now less aggressive and will not try to maximize peer utilization, but minimize redundant downloaded bytes.
The end-game mode has been restricted so it is only entered into once all pieces in the torrent have been requested at least once.

So, the aggressive nature of the application, which was originally written to take advantage of the coder's very fast line (he didn't care if he downloaded a piece more than once if he got the whole file faster) has been toned down.

I'll be releasing Deluge 1.2.1 tonight/tomorrow and it will depend on the recently released libtorrent 0.14.9. The new version of libtorrent fixes the issue of overdownloading and changes how we report downloaded statistics to the tracker. This change will make Deluge act more like uTorrent in regards to tracker reporting.

Any chance to get it at the same time on the PPA ?

that depends on the maintainers.
