• newslink.js - import PTRs

    From Ash-Fox@VERT to DOVE-Net.Synchronet_JavaScript on Sat Nov 17 00:04:08 2007
    Greetings all,

    Recently I've linked my BBS to a rather unreliable news server (there is
    unique groups on there that other news servers don't have). Unfortunately because of it's unreliability I've had a bunch of issues trying to mirror
    all the content, as I keep running into various problems such as:

    - Random disconnects
    - Infinite loop (100000000 branches) detected issue

    To get around the Infinite loop problem, I tried setting at the beginning of newslink.js the following:

    branch_limit = "0";

    Unfortunately, that seems to do nothing at all.

    Whenever a random issue happens, be it disconnection or infinite loop, the message import PTRs are not updated, so, the BBS starts from the beginning
    and ignores a bunch of messages after downloading them as it already has
    them.

    I looked at the sourcecode of where the pointers are retrieved, from my understanding it's from the .snl file in /data/subs/. Unfortunately when I
    open it up, it's in some binary format I don't quite understand. Looking at
    the javascript code, used newslink.js, I'm just not getting how it's set.
    So I can't manually fix the number.

    I've resorted to temporarily hardcoding the PTR number in the newslink.js,
    but I think a better workaround would be updating the PTR number in
    the .snl file everytime a article is downloaded, rather than when the
    entire transaction is complete.

    While I do more or less understand what's going on in newslink.js, I'm
    really confused about what I would need to modify in the file to make this happen and would appreciate help on this. I also consider the fact that
    PTRs aren't updated with every article download is a bug.

    Unfortunately, that seems to do nothing at all.

    That's because branch_limit is a property of the 'js' object, so you would want to use:

    js.branch_limit = 0;

    instead.

    Whenever a random issue happens, be it disconnection or infinite loop, the message import PTRs are not updated, so, the BBS starts from the beginning and ignores a bunch of messages after downloading them as it already has them.

    A disconnection will not cause the PTRs to not be updated. Only a JS exception (like the infinite loop detection) would cause that.

    I looked at the sourcecode of where the pointers are retrieved, from my understanding it's from the .snl file in /data/subs/. Unfortunately when I open it up, it's in some binary format I don't quite understand. Looking at the javascript code, used newslink.js, I'm just not getting how it's set.

    I'd suggest limiting the number of messages downloaded per execution of newslink.js and that'll avoid the problem altogether with no modification of newslink.js necessary.

    Thanks for the help.
