trackers removal problem

[tekko]

qbt v2.9.11, libtorrent v0.16.1, xp sp3

If you remove all trackers from a torrent under the trackers tab, its default trackers will always be restored upon restarting qbt.

Confirmed in v3.0.0rc3.
Might be by design though..
Isn't at least one tracker required to start or resume a download?

[Christophe Dumez (hydr0g3n)]

No, this is supposed to work. libtorrent started to support default trackers removal a while back and it used to work. I'll check.

[Christophe Dumez (hydr0g3n)]

Well, I cannot reproduce (I can remove all the trackers and then restart qBT and they are still gone). It works just fine for me. Maybe the fastresume data failed loading? (Could you check from the log window).

[King Tomaso (tomasotheking)]

No fastresume error.
Here's the log:

Also no fastresume error for me on qbt v2.9.11. I've posted the link to this bug report in the forum. Maybe it's a windows only problem again...

[Veikko Mäkelä (veikk0.ma)]

I can confirm this on qBittorrent 3.1.9.2 with Win7. I remove trackers, close qBittorrent, start it again and all the trackers are back.

Libtorrent 0.16.16.0
Boost 1.55.0

If you want to test with the specific torrent I used to reproduce this you can use the torrent of the Windows version of LibreOffice 4.2.2.
