News: BIP91 seems stable: there's probably only slightly increased risk of confirmations disappearing. You should still prepare for Aug 1.

Pools usually selectively request submitold on work items, usually for merged mining reasons - that is because a share for an old nmc block is still a relevant share for the existing BTC block. Most pools do not universally enable it except in the case of p2pool.
Eloipool always enables submitold. There's no real reason not to enable it, unless the pool wants to misreport a lower stale rate.

Ah there was also one bug where submitold was not being checked on re-submission. This has been fixed in my git tree.

Likely a simple fix but trying to run cgminer 2.3.4 under Debian 6.01 x64 I get

./cgminer -n
cgminer: error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or directory

Any ideas?


Nevermind I finally stopped being a Linux wimp and using the prebuilt binary and compiled it myself.  It only took .... (don't laugh I am a SQL Server developer by trade) ... little over an hour.

Still I learned something and it working fine now.

I tried moving my hard drive from a motherboard that only had one GPU to a motherboard that had three GPU's plugged in.

I did the sudo aticonfig -f --adapter=all --initial and rebooted, I also deleted the .bin file in cgminer's directory.

CGminer gave an error about the number of devices not matching. It saw three devices, but OpenCL was only seeing one?

Where else does OpenCL know about the number of video cards besides xorg.conf and what else should I have done besides running aticonfig?

The system was build with these instructions: https://github.com/kanoi/linux-usb-cgminer/blob/master/linux-usb-cgminer

Updated git tree:
The most significant change is a massive change to the way network connections are made, so there should be MUCH less connections opened which should more or less abolish the overloaded networks people use. Also longpoll is now tied to each pool set up, but only the longpoll attached to the primary pool causes a work restart. Also updated ztex support.


Changelog(reverse order):
Start longpoll only after we have tried to extract the longpoll URL.
Check for submitold flag on resubmit of shares, and give different message for stale shares on retry.
Check for submitold before submitstale.
Don't force fresh curl connections on anything but longpoll threads.
Create one longpoll thread per pool, using backup pools for those pools that don't have longpoll.
Use the work created from the longpoll return only if we don't have failover-enabled, and only flag the work as a longpoll if it is the current pool.
This will work around the problem of trying to restart the single longpoll thread on pool changes that was leading to race conditions.
It will also have less work restarts from the multiple longpolls received from different pools.
Remove the ability to disable longpoll. It is not a useful feature and will conflict with planned changes to longpoll code.
Remove the invalid entries from the example configuration file.
Add support for latest ATI SDK on windows.
Export missing function from libztex.
miner.php change socktimeoutsec = 10 (it only waits once)
Bugfix: Make initial_args a const char** to satisfy exec argument type warning (on Windows only)
miner.php add a timeout so you don't sit and wait ... forever
Create discrete persistent submit and get work threads per pool, thus allowing all submitworks belonging to the same pool to reuse the same curl handle, and all getworks to reuse their own handle.
Use separate handles for submission to not make getwork potentially delay share submission which is time critical.
This will allow much more reusing of persistent connections instead of opening new ones which can flood routers.
This mandated a rework of the extra longpoll support (for when pools are switched) and this is managed by restarting longpoll cleanly and waiting for a thread join.
miner.php only show the current date header once
miner.php also add current time like single rig page
miner.php display rig 'when' table at top of the multi-rig summary page
README - add some Ztex details
api.c include zTex in the FPGA support list
api.c ensure 'devs' shows PGA's when only PGA code is compiled
cgminer.c sharelog code consistency and compile warning fix
README correct API version number
README spelling error
api.c combine all pairs of sprintfs()
api.c uncomment and use BLANK (and COMMA)
Code style cleanup
Annotating frequency changes with the changed from value
README clarification of 'notify' command
README update for API RPC 'devdetails'
api.c 'devdetails' list static details of devices
Using less heap space as my TP-Link seems to not handle this much


So, is this all currently reflected in 2.3.4 ? or upcoming in 2.3.5 ?

Eloipool always enables submitold. There's no real reason not to enable it, unless the pool wants to misreport a lower stale rate.
I'm not sure what Eloipool is, but assuming it is the backend for Eligius, yes, that output was while mining on Eligius.  Incidentally, if you go back to the original quote, I was then, too, but I don't think you were active in this thread yet.  However, it sounds plausible that I could have been witnessing this:
Ah there was also one bug where submitold was not being checked on re-submission. This has been fixed in my git tree.
In which case I will need to update to 2.3.5 (which might also help with my disconnects if it has fewer sessions as previously indicated.

NEW RELEASE - VERSION 2.3.5, 28 APRIL 2012

Human readable changelog:
Much nicer on networks, should have significantly less connections and not induce network congestion. This will help both miner and pool hardware.
Much smoother across longpolls, uses one longpoll per pool now at all times
Simpler screen output, yet more info
More ztex hardware support
New diakgcn kernel
Numerous bugfixes surrounding stale handling and display
Updated miner.php
--no-longpoll does not exist any more
Numerous min(e)r improvements Wink

Full changelog:
- Restarting cgminer leads to a socket that can't be bound for 60 seconds, so
increase the interval that API binding waits to 30 seconds to minimise the
number of times it will retry, spamming the logs.
- Give a longpoll message for any longpoll that detects a block change, primary
or backup, and also display which pool it was.
- Decrease utility display to one decimal place.
- Small cosmetic output alignment.
- Add pool number to stale share message.
- Add space to log output now that there is more screen real estate available.
- Indentation clean up.
- Merge branch 'master' of github.com:ckolivas/cgminer
- Remove thread id display from rejected shares as well.
- Merge pull request #185 from Diapolo/diakgcn
- add goffset support for diakgcn with -v 1 and update kernel version
- Set have_longpoll to true when there is at least one pool with longpoll.
- Don't display the thread ID since it adds no useful information over the
device number.
- Don't display the first 8 bytes of a share since they will always be zero at
>= 1 difficulty.
- work->longpoll is reset across test_work_current so we need to recheck what
pool it belongs to.
- Use longpolls from backup pools with failover-only enabled just to check for
block changes, but don't use them as work.
- Start longpoll only after we have tried to extract the longpoll URL.
- Check for submitold flag on resubmit of shares, and give different message for
stale shares on retry.
- Check for submitold before submitstale.
- Don't force fresh curl connections on anything but longpoll threads.
- Create one longpoll thread per pool, using backup pools for those pools that
don't have longpoll.
- Use the work created from the longpoll return only if we don't have
failover-enabled, and only flag the work as a longpoll if it is the current
pool.
- This will work around the problem of trying to restart the single longpoll
thread on pool changes that was leading to race conditions.
- It will also have less work restarts from the multiple longpolls received from
different pools.
- Remove the ability to disable longpoll. It is not a useful feature and will
conflict with planned changes to longpoll code.
- Remove the invalid entries from the example configuration file.

Queued work seems to be about 6-7x normal for my setup. At start, LP looks like it's being enabled for multiple pools. Ran 1k shares with 2.3.4 to verify, and E was much higher than 2.3.5 using the same conf.

Yes, the changelog said as much... LP is being used on every pool you are connected to now.

Great work Con and my goffset mod for diakgcn also works Smiley.

Edit: One small glitch, after pressing Q and a succesful shutdown on Windows at the end is this line here
Code:
[201S2h-u0t4d-o2w8n  1s0i:g5n5al: 2r0e]c eliovnegdp.o

Could there be an overwritten char * buffer or sth. like that?

This looks like two threads are writing to the console at the same time, interleaving their characters Smiley
So it's probably harmless, just a logging annoyance...

Judging from the garbage you posted, the original messages seem to have been:
Code:
[2012-04-28 10:55:20] longpoll
Code:
Shutdown signal received.

Heh - nice detective work.
I can clearly see how you got the answer!
Now I can make sense of it also when I'm windows testing
(I always thought it might be windows printf's fault with variable sizes - but that clearly shows it isn't)
Yeah curses on windows is ... well ... 'nuff said.

What's the theory of operation of the Utility now?  Prior versions it was the overall average.  Now it appears to an instantaneous or a small time period average.
Thanks,

99.9% sure that, That is what it did, Is it possible to use the kernal i saved from 2.1.2 for 2.3.3 Or must i go install old drivers, Complie a .bin, Save it, Install new drivers again, Replace the .bin like i've done before

Maybe.  Try and find out.  There are some incompatibilities between drivers but generally they "play nice".

Also driver =/= SDK.
AMD package installs them together but you can install/uninstall just the SDK.

So you can install the latest driver and SDK 2.4 for example.
On a new install just make sure to ONLY install the driver you want and then ONLY install the SDK you want.

The one exception is SDK 2.6 which is broken and an ass to uninstall completely.  There is a thread about it somewhere.  Another option is I think conman has compiled kernels (bin files) on a server somewhere.

Well the .bin files do not work with difffernt miner versions, *sigh* I'll wait a few more years before i uninstalled all my drivers, Install old ones, install old sdk, Reboot, run cgminer, Save bin, Uninstall drivers, Reboot, Install new drivers, reboot, TEST
