Issues ?!?

[MDFaunce]

I noticed a couple of things.

While running SB client on Windows, it keeps some TCP connections intact:

C:\WINDOWS>netstat | find "sb.pns.net"
TCP shade:1315 sb.pns.net:1717 CLOSE_WAIT
TCP shade:1367 sb.pns.net:1717 CLOSE_WAIT
TCP shade:1420 sb.pns.net:1717 CLOSE_WAIT
TCP shade:1459 sb.pns.net:1717 CLOSE_WAIT
TCP shade:1496 sb.pns.net:1717 CLOSE_WAIT
TCP shade:1497 sb.pns.net:1717 CLOSE_WAIT
TCP shade:1500 sb.pns.net:1717 CLOSE_WAIT
TCP shade:1504 sb.pns.net:1717 CLOSE_WAIT

If left around long, enough, you get more and more of these. It looks to me like these connections are only closed when you submit a completed n or stop/start the client.

Also, I've gotten some strange displays on some blocks. Basically, it looks like when the n is very small that messes up some internal computations. It says it's going to complete the full test *before* it completes the block, even though there is only one block. Also the time remaining is messed up when this happens. I never noticed it on the higher n runs, but on these recent ones with small n it's been a lot more frequent.

I have about 80 of these open right now. CLOSE_WAIT's usually linger around for a few minutes... but not days :/ Probably a small bug in the code.

Yep. There are some calculation details being worked out, no doubt, by Louie, for both the win client and the stats online.

MDFaunce - i already wrote you an email about this so i don't understand the post. there is certainly no "[messing] up some internal computations". the client is behaving fine.

yes, it is true that in the last block, the block compeletion time isn't correct but that is a small point. usually isn't noticed although the low n's make it more noticable. for now, ignore that and i'll possibly change it in the future.

that's an interesting observation with windows networking. i'd buy that there are 8 open connections. "about 80" as shifted claims sounds a bit high. personally i have 12 on my workstation here.

blame Gates. ;) basically i don't reuse connections. i close them after each transmission rather than keeping a constant connect. so it opens a new socket for each transmission. my server closes it but windows must not believe it. netstat obviously works in linux so if there is a similar "problem", i'll look into doing something about it.

Actually, it's 130 right now (client has been running for over 107 hours.) You can count them, if you wish ;) However, i haven't noticed any ill effects, so i'm not concerned.

yes, it is true that in the last block, the block compeletion time isn't correct but that is a small point. usually isn't noticed although the low n's make it more noticable. for now, ignore that and i'll possibly change it in the future.

There are more strange things with the time remaining. Sometimes it's a very high (tens of thousands hours), sometimes it counts down to zero, and sometimes the time remaining is the time the client is running plus a couple of seconds.

No big deal though, just thought i mention it.
