File check, hash check Can it be skipped?

[Bmflufff]

Hi folks,

File check, hash check Can it be skipped? as when uploading large files it takes ages to check, can this be skipped and just seed straight away like u can with utorrent?

sweet app btw well done

Hello,

I also would like to say, that this skipping would be very nice thing, and as I remember in one version of deluge-torrent, on start-up no checking were made.
And of course I want to thank you for your work in this open source project, and I hope that the idea about possibility to categorize torrents would be realised soon.

Thank you!

Hashing shouldn't be skipped IMO, since you risk sending corrupt data to users, this uses unnecessary bandwidth.

But, for the upload of larger files to start faster one could imagine Deluge comparing hashes not from the start of the file to the end, but based on which data pieces it wants to send.

Ie. Deluge starts and finds out which pieces someone is requesting and then does a hash check on that piece before sending it. It marks that piece as good if it matches and tries to redownload it if it doesn't match. Ie. a non-linear order of hashing based on which pieces are requested by peers.

That sounds a lot like super-seeding... except with the added step of course.

Any update on this is hash checking is going to be added? not need is you know u have all the files, say a 4gb dvdr

hash checking can't be skipped however files should only get checked if deluge didn't shutdown properly or if you start downloading a file to a location where a file of the same name exists.

I find that when deluge starts up it picks (seemingly) random torrents (usually ones that are done downloading) and checks them, even though I always exit the client normally. This is pretty annoying, especially if it picks some 15 or 20Gb torrents. It is an improvement though; a few versions ago I remember it used to check all of the files every time. It would be nice if this would be fixed, though.

I know I'm new but I've been watching deluge and used it several times when trying new distro's and this feature would be greatly appreciated.

Nothing is more frustrating than finally finishing downloading something, and then as you go to seed it elsewhere (new .torrent) it has to sit there and check. uTorrent's skip check works flawlessly and fast.

Deluge need a skip Hash check function

This will be available in libtorrent 0.15, so I will try to add this option to Deluge 1.3.
