Feature Request: Add Tracker to Torrent

[0x27]

A good feature to have would be the ability to add a tracker to a torrent that appears to be badly seeded (or relying on some dead trackers). For whatever reason, this usually works out pretty well for me in other clients to "revive" torrents that initially seem to be dead.

Definitely interested in this feature as well. Over 90% of the trackers included are dead, which make it much more difficult for Tribler to get started.

I wrote python hack to wipe all trackers from the entire DB and inject my own, it's not overly pretty but it works, and maybe someone else can find it useful.

injecttrackers.py

We have facilities to add trackers to downloads:

tribler/src/tribler/core/libtorrent/download_manager/download.py

Lines 867 to 870 in 3e6a3e2

	def add_trackers(self, trackers: list[str]) -> None:
	"""
	Add the given trackers to the handle.
	"""

We could implement this feature by simply exposing this method to the GUI.

I tried the approach that I mentioned above and this seems to work just fine. Now, I need an GUI design. I'm thinking of adding a column to the trackers table of a download's details:

Add/Remove	Tracker	Status	Priority
	[DHT]	Working
	[PeX]	Working
( Remove button )	Tracker 1	Working	↕
( Remove button )	Tracker 2	Not contacted yet	↕
( Add button )	[ INPUT FIELD ]

When solving this, we should probably also include #1797 and allow the GUI to move trackers "up and down" to increase/decrease their priority. I updated my previous post with a "priority".

My initial prototype is here: https://github.com/qstokkink/tribler/tree/add_tracker_add

I think I'll drop the initial prototype though. After sleeping on this, I think it might be better to simply have a right-click context menu that allows you to change tracker priority, remove trackers, and add a tracker.

[qstokkink]

We can use react-sortable-hoc to re-order trackers to change their priority.

Demo: http://clauderic.github.io/react-sortable-hoc/#/basic-configuration/drag-handle?_k=29udje
Source: https://github.com/clauderic/react-sortable-hoc/blob/master/examples/drag-handle.js

This avoids a right-click context menu, which is not really "web-like".

Looking into how libtorrent handles trackers, order doesn't really exist - only tiers. Perhaps it's better to simply have a "Check Tracker Now" button.
