  • Bug#1103416: Transmission 4.1 beta shredding local data

    From Stephan =?ISO-8859-1?Q?Verb=FCcheln@21:1/5 to All on Thu Apr 17 12:10:01 2025
    Package: transmission-gtk
    Version: 4.1.0~beta2+dfsg-2

    For a few weeks, I was seeding some rare torrents with Transmission
    4.0. After the update to 4.1 beta, Transmission started to “verify
    local data”, discarded the torrent data and started downloading from
    scratch.

    * I am using Transmission GTK in Gnome.
    * At the time, I was seeding five torrents with multiple files,
    totalling around 200 GB.
    * The filesystem is ext4 (within LUKS on SSD).
    * The location is ~/Downloads/Torrents/, which was configured to be
    the default location in Transmission.

    Unfortunately, I have not identified the root cause and I cannot
    provide examples for privacy reasons. I filed this bug anyway to raise awareness and block migration to Trixie.

    Regards
    Stephan

    Hi,

    For a few weeks, I was seeding some rare torrents with Transmission
    4.0. After the update to 4.1 beta, Transmission started to “verify
    local data”, discarded the torrent data and started downloading from scratch.

    Sorry to hear that.

    I've been using 4.1.0~beta2 for 3 months and it has worked well for me.

    I have one 8 Gib torrent which transmission insisted on downloading most parts again arguing invalid data, but this was not automatic and I had to ask to "Verify local data" before any data shredding happeneded.

    Other torrents, from 3 Gib to 163 Gib, have been downloaded with earlier versions and have been well since.

    Could you provide an anonymized log have what happeneded?

    I cannot find any issue referring to something similar upstream, but probably beta versions do not get much testing.

    Will raise severity if I get another report on this, but without logs,
    it is difficult to have a hint about what might have happened for you.

    Thanks,

    Alex
