Don't open connections to web seeds when not downloading

[Federico]

I'm uploading/seeding a few torrents, which are available on the file system and on several web seeds (​https://tools.wmflabs.org/dump-torrents/ ). I observe that whenever I restart deluged, or I add new torrents, TCP connections are opened towards the web seeds for a large portion of torrents (all the non-seeding ones? the checking ones? I'm not sure) and stay open for a while. 0 torrents are in "Downloading" state.

Disregarding the total number of torrents and connections (​https://meta.wikimedia.org/wiki/Mirroring_Wikimedia_project_XML_dumps/Torrents/deluge/core.conf ), I don't understand why deluged would open a connection to a web seed in the first place when it doesn't need to download anything.

Whenever a local path was specified and the torrent has not been verified yet, the web seeds should be ignored. The web seeds should be checked/contacted only when the torrent is in downloading state.

lsof -c deluged | grep TCP

deluge-console "info -v" (part 2)

Actually, from the attachments it looks like most/all web seeds are opened by torrents in error state, like:

This is something to do with libtorrent what version are you using?

[Federico]

$ deluged --version deluged: 1.3.10 libtorrent: 0.16.18.0

[Calum]

Can you test with libtorrent 1.0 as the that is current stable code.

[Federico]

I'm trying:

$ sudo apt-get -t sid install libtorrent-rasterbar9 libboost-chrono1.62.0 libboost-random1.62.0 libboost-system1.62.0 libssl1.1 libstdc++6 gcc-6-base libboost-python1.62.0 $ deluged --version deluged: 1.3.10 libtorrent: 1.1.1.0

Ok?

[Federico]

That didn't run (fatal errors, segfaults and whatnot) and I don't have time these days to build the exact compatible versions myself. I'm back to:

$ deluged --version deluged: 1.3.10 libtorrent: 0.16.18.0

[Calum]

I did say 1.0 not 1.1. If you are on Jessie then use the Trusty repo from Ubuntu PPA ​https://launchpad.net/~deluge-team/+archive/ubuntu/ppa

[Federico]

Ah, thanks. I wish I had known 2 hours ago. :) However I'm on Debian 8 now.
