"webseeds" don't respect download speed settings

[Jan Claeys]

It seems like "webseeds" (where a file gets downloaded using http from a web server instead of using the bittorrent protocol) don't respect the download speed-settings the user sets in Transmission.

I found this out when downloading the 720p version of the new Blender movie "Tears of Steel"[1] using Transmission resulted in my internet connection to become saturated, and all other torrent downloads to be interrupted (because 20 Mbit/s is more than the 750 KB/s I had limited Transmission to).

Status changed to 'Confirmed' because the bug affects multiple users.

I can reproduce this bug with Transmission 2.51. Here's a screencast showing it in action with a Kiwix webseed download:

I can also reproduce this bug with Transmission 2.77 (in an Ubuntu 13.04 environment). The torrents I am downloading are from librivox.org.

I don't understand all the "additional information" provided by the previous poster, but I can provide the same information for my own situation:

This is fixed in 2.80, which has been released on Ubuntu.
