I noticed that my miner wasn't showing up in the block distribution history at times. Here's an example where it's registering fine up to block 575, disappears during blocks 576 and 577, then returns at block 578.

I believe when happy spammed it, it went down until Microsoft restarted the app pool automatically.

Ill work on spam prevention also.

Its up.



test coins have no value .  right ?
None at all.

Not really related to the test pool, but this is an issue I see a lot even on the main blockchain:

Code:
Block  Timestamp
548    8/9/2017 9:45:08 AM
549    8/9/2017 10:44:51 AM
550    8/9/2017 10:44:51 AM

It'll go about an hour with no blocks, then that fail-safe difficulty reduction kicks in and you often see it followed by 2-3 blocks that are mined instantly. Do you think this is something that will work itself out when the network hashrate starts going up? I don't really know enough about blockchains to speculate on any security issues that might arise from the low difficulty blocks, but at the very least the inconsistency in block time might have an affect on widespread adoption of Biblepay since it directly affects the speed of transactions.
I have observed this also on all the chains.  I believe the issue is (the chain) eventually selects a difficulty for the next block that is slightly too hard for the miners, probably due to either them getting lucky on the last block, or, maybe some extra miners piling in the wallet.

Anyway, I doubt more hash rate will solve the problem, it might make it less frequent.
I think what we need to do is when we have another mandatory, add in two features in it:
- Retarget difficulty once per block instead of once per 4 blocks
- Lower the threshold for the stuck blocks from one hour to say 35 minutes.  It has to be well over 15 minutes, because the timedrift function for getting the network adjusted time is 15 minutes, and that enforced block drift for disallowing future mining (IE clocks could be off, per se, up to say 7 minutes or so) is used, but we could probably go with 35 minutes for stuck blocks, and that would keep our chain running smoother, and not have people hanging around waiting for confirms.

Go ahead and try to spam the pool now.

Got to jump out for a little while; spam prevention should be enabled on miner actions, ips, and withdraws.

Hmm, I think I might've killed the pool website. I tried spamming withdrawals to see if it handled it okay. Seemed to be fine while I was spamming it manually, then I set up an autoclicker to hit send about a hundred times a second and now the web server seems to be busy or dead.


looks like ....

Some feedback:

1. When you click on switch to testnet it toggles to switch to mainnet. When you click on another like like home, the link switch to mainnet defaults back to switch to testnet which is not correct.
2. There is no page to see stats on the blocks found, who found them, when found, the block's status etc.
3. No anonymous mining option.
4. Pool hash indicator is very close to client side hash
Hi JC,

Thanks for the detailed info.
I agree, #1 is a nuisance, however, the reason it made it so far is the affinity to main_chain, so Im not sure if that will stay that way or not.  The thing is in my experience, once we finish testing we will really for all intents and purposes always be in the main chain.   (To fix this I need to move the setting for your selected chain to Account to a drop down, and then put the indicator (of the active chain) somewhere else- Ill see what I can do).

On #2, check out block distribution history report.  It should have very good details.

On #3, nice idea.... Hmmm, thinking about it.

#4, cool.

And I have a new bug to add:

I think others might have experienced this also.  I have a few nodes solo mining and they are unaffected by this bug.
At 02:45 am this morning we have 5 miners on testnet pool mining.  Myself and I believe 2 others fell off at the time the tithe block hit. I believe our testnet miners crashed.
I believe the issue is, whatever is sent back to the client (either HTTP error, or possibly since the tithe block was mined, an ERROR type response) was handled in a way that caused an unhandled exception to close the whole client.  I will look into this today, and believe this Only affects pool miners.

running a test with a laptop since it looks like im going to need pool mining before i ever get a coin. Spun up an 8 core azure machine with free credits and still nothing so far.

Anyway only thing i noticed so far is in your portal you are not checking for logged in status. I left and came back and clicked on a link and got a hard error instead of sending me back to the log in screen.


We check for logged in status- please paste the error so we can debug.

Invalid column name 'threads'.
Invalid column name 'BoxHPS'.

Thanks a lot dude!  So of course when we go live, we can turn off verbose debug info.  But this helps, as this is basically a spoof URL security item, in a way.  On a side note, this happens when the users session auto-expires and then they try to spoof a URL.  Ill jump on this.

Some feedback:

1. When you click on switch to testnet it toggles to switch to mainnet. When you click on another like like home, the link switch to mainnet defaults back to switch to testnet which is not correct.
2. There is no page to see stats on the blocks found, who found them, when found, the block's status etc.
3. No anonymous mining option.
4. Pool hash indicator is very close to client side hash

running a test with a laptop since it looks like im going to need pool mining before i ever get a coin. Spun up an 8 core azure machine with free credits and still nothing so far.

Anyway only thing i noticed so far is in your portal you are not checking for logged in status. I left and came back and clicked on a link and got a hard error instead of sending me back to the log in screen.


We check for logged in status- please paste the error so we can debug.

I disconnected from the pool and solo mined blocks 411 and 412 to see how the pool would respond to an outsider mining a block it was working on. The blocks were definitely solo mined and the block rewards were added to my wallet's immature balance. The block distribution history gives the impression that the pool still paid out to pool miners for those blocks:

Code:
ID					User Name	Height	Block Subsidy	Subsidy		Paid Date		HPS	PaymentPerHash	Updated			Stats
13a88588-0b07-42da-a8a7-256595d1438c flyingfish 411 20000.0000 20000.0000 8/8/2017 10:27:59 AM 733.49 27.266777209204 8/8/2017 10:27:59 AM testnet2: 551 (733)
de9a39f5-fb2a-4605-95ae-4aa1bbcf3788 flyingfish 412 20000.0000 20000.0000 8/8/2017 10:27:59 AM 733.49 27.266777209204 8/8/2017 10:27:59 AM testnet2: 551 (733)

I didn't have a miner connected to the pool at the time so I can't verify whether or not pool miners were actually mistakenly credited for those blocks from my end.

Im glad we are still testing as we need to work out the finer kinks.

So good news is some things behind the scenes partially worked but you did find a bug.
So on block 411 (when you pulled out of the pool) you didnt actually get that block, the pool still got it (if you do a 'run subsidy 411') you see the pools testnet address.  So that explains how flyingfish got the whole block 411, so that park worked correctly.
But by the time 412 hit, here is the pool bug hitting:  It did successfully double check 412, and find it was not paid for it, and avoided putting it in the blocks table, but for some reason, it went ahead and distributed the block and paid it, so I can see a condition where it realized it should not pay it but executed the remaining part of the service; Ill look into that now, but anyway this is very helpful.  Looks like we need to keep testing for a while longer and insure this is killed.

Thanks.



Ok,

I fixed the two outstanding pool issues:  Balance is updated correctly now on the withdrawal form, and I found the condition where we pay when we should not pay, and corrected the logic.  Im going to mine against the testnet pool again and see if we can make this solid now.  We still need a few testers in testnet for a couple days, please join us, having only two of us is not very effective to exploit bugs.

Thanks.
