When I leave KTorrent 2.2.8 running for some days, its log files get full and get rotated. Unfortunately sometimes a KDE dialog appears asking whether to overwrite "log-1" with "log" (if I remember it correctly). Anyway, without user interaction (leaving the dialog open), KTorrent appears to start to consume large amounts of memory, which could render the machine unresponsive. Tracing the source code lead me to a part in libktorrent/util/autorotatelogjob.cpp which appears to try to move a file twice, resulting in a race:

Code: Select all

if (cnt == 1)
{
        // move current log to 1 and zip it
    bt::Move(file,file + "-1",true);
    KIO::Job* sj = KIO::file_move(KURL::fromPathOrURL(file),KURL::fromPathOrURL(file + "-1"),-1,true,false,false);
    connect(sj,SIGNAL(result(KIO::Job*)),this,SLOT(moveJobDone(KIO::Job* )));
}

I know that you won't likely be relasing a new version for KDE 3, but as I'm using KDE 3.5.10 which is currently the latest "Stable" KDE version in Gentoo, I still hope to fix this issue under Gentoo. So please tell me whether I'm on the right track or whether there's a way to turn off that logging completely as a workaround?

That looks like the bug

Ok, I submitted a bugreport at Gentoo with a patch hopefully fixing this.
