Fetch metadata of stopped magnets

[legacychimera247]

azureus vuze has the ability to let me choose which files i want to download from a magnet file before starting the download...transmission just start the download of the entire file...would be nice to have that feature in transmission too...

an example : click on magnet , azureus opens and download magnet infos, ask what to download from magnet and then starts to download...transmission just start without asking...

So what you actually want when you add a magnet in paused mode is to have Transmission download the metadata and then stop. Why not ask for that?

Why is this closed? What is the solution ?

Looks pretty open to me @Nishantkumarsah

Yes, I'd like this feature to be implemented too, it would be very useful, especially when there are a lot of large files in the torrent and you just need some of them, and this is a very common scenario from what I see.

This would be super useful. What I have to do now is start the torrent from the magnet link, wait for it to download the metadata and inevitably part of the file data as well, then immediately stop the torrent, select the files I want, delete any unnecessary pieces that already downloaded, restart the torrent.

Also note this issue had a bug in the old bug tracker with a patch attached... might just be a matter of reviewing the patch and tweaking as necessary.

@elisimpson : you might want to keep an eye on #852 related with what you currently do as workaround

[elisimpson]

@pataquets : I actually found a better workaround, which is start the magnet link with qbittorrent, which can download the metadata without starting the torrent. Then I save the metadata to a new torrent file and load it in transmission.

Just adding my 2 cents: there is an old ticket on trac for this as well, and it has an attached patch but it is 7 years old…

@elisimpson you can also use a service such as Magnet >> Torrent to do that.

Can we get this PR merged please? ^^

[rheicide]

Please correct me if I'm wrong but it looks like magnets are not having their metadata fetched after being added with "Start when added" unchecked, which in my understanding is the goal of this issue.

If this is the case, it's probably related to the fact that the prefetchMagnetMetadata flag introduced by #1080 was later removed by #3013.

Can someone give an explanation as to why this feature was removed? It's annoying to deal with having to download part of a torrent files just to see their metadata. And why is this issue closed if the problem hasn't been solved?

[GaryElshaw]

The issue is alive elsewhere. The function itself opened a lot of debate. Some contributors made the case that sometimes metadata is 'data-sized'; and others that zero data should be allowed if start when added is unchecked. I hope this PR is revisited and added #4874. CC @Coeur

Ah, the metadata is also data discussion. 'Download[ing|ed] metadata' should at least be defined steps in the download process. Now they are contained within 'Downloading'.
