Talking 8 Zettabyte barrier for credits

K, let's say some user have 0 b in credits

SITE CHANGE USER CREDITS +9223372000000000000
Site reports : Credits: 9007199218750000MB

Now reset it to 0 b again

SITE CHANGE USER CREDITS +9223373000000000000
Site reports : Credits: -9007198314169484MB

Not talking about all those scripts that reports credits to IRC...


PS:

9007199218750000 Megabyte
8796092987060.546875 Gigabyte
8589934557.6763153076171875 Terrabyte
8388607.9664807766675949096679688 Pettabyte
8191.9999672663834644481539726257 Exabyte
7.9999999680335776020001503638923 Zettabyte

That's probably an integer overflow. The credit/stat sections in the userfile are signed 64bit integers, like all other integer data types there is a limit.

Well it's not really a bug...it's by design. The max size of a signed 64bit integer is from -9223372036854775808 to 9223372036854775807 (0x7FFFFFFFFFFFFFFF). Once you the exceed either the positive or negative limit, the integer overflows.

This can't really be fixed, unless darkone is up to writing some make-shift limitless large integer support (I've seen it done, I just forget what it's called :P). The disadvantage is, that it's much slower and we know how darkone feels about optimization and speed.

Hm, yeh, I see, thnx for the explanation. And yeh, speed is everything, agreed on that. Don't see the reason to fix this "bug" either... Nobody would get 8Zb credits anyway, heh.

if somebody did get over a ZB of credit they should be delusered just for giving so much without taking any, based on the principle of over-generosity.
