Transmission stays stuck with "torrent metadata needed":

I'm using Transmission 4.0.6 (38c164933e) on Mac OS Sonoma 14.5 (Apple Silicon).

Note that the ZIM has been very recently (yesterday) pushed to storage / published in library.

Adding to Transmission the torrent manually downloaded from xs attribute above works like a charm.

@rgaudin can you please have a look, I'm not that experienced with magnet links and I honestly don't get what could be wrong here

This is "normal", it looks like transmission is not using the xs parameter at all: https://github.com/transmission/transmission/issues/317 ; so it waits for peers to download metadata

[rgaudin]

Indeed, as verified with @benoit74, there are very few torrent clients that supports automatically downloading the .torrent file themselves from the the xs key.

This means that for them, even a webseed-able magnet is not enough if there is no peer providing the metadata. This makes #43 very important.

Clients supporting xs:

• Tixati Windows, Linux (Freeware)
• exatorrent CLI with Web UI macOS, Linux, Windows, Docker (GPLv3)

We did found a bug that affects qbittorrent: https://github.com/kiwix/libkiwix/issues/1157
