• First-time scan pointer value

    From Nightfox@VERT/DIGDIST to Digital Man on Saturday, August 06, 2016 09:27:19
    Hi DM,

    I've noticed a possible issue with the scan pointer for a new user with Synchronet 3.17. The first time a new user starts reading one of the sub-boards, msg_area.sub[subBoardCode].scan_ptr has a very high value, 4294967295. I'm not sure if that's valid or not. I have a message reader mod I wrote in JavaScript, and it has had trouble accessing messages for new users, seemingly due to that value of scan_ptr. I found that I can check for that value and work around it, but I still wanted to let you know in case that value is not by design.

    I'm running Synchronet for Windows. I noticed the issue a couple weeks ago. I was running the Synchronet build from January 3, 2016, then I updated to the latest build at the time (July 23) and noticed the issue was still there.

    It's not a valid message number, but it is a valid pointer value (0xffffffff) which indicates that user's message scan pointer should point to the *latest* message number when the msg pointers are save for the first time (e.g. when a new user logs off). This should only occur:

    1. If you have SCFG->System->New User Values->Days of New Messages set to 0.
    2. And a new user logs on for the first time

    I think the default for "Days of New Messages" is not 0. Did you change it? 0 is valid, but it means that a new user would see *no* new messages when they first scan for new messages upon logging as as "new". I just want to make sure you knew how that worked.

    I have a message reader
    mod I wrote in JavaScript, and it has had trouble accessing messages for new users, seemingly due to that value of scan_ptr. I found that I can check for that value and work around it, but I still wanted to let you know in case that value is not by design.

    Yes, it's by design. It was added in Nov-2015 with this commit: http://cvs.synchro.net/cgi-bin/viewcvs.cgi/src/sbbs3/userdat.c?r1=1.160&r2=1.16 1

    ~0 (of a 32-bit integer) is short-hand for 0xffffffff.

    I think it's going stay that way too. :-)

    That (0) is actually the default now. So you probably didn't change it. But before Nov-2015, new users had *all* messages marked as "new" (and scan ptrs would be initialized to 0).

    I'm using Sync 3.16c and not have Days of News Messages field
    on New User Values. How can i upgrade this?

    TIA

    You can upgrade to the daily development builds (sbbs_dev.zip for Windows).
