I hope this is the correct forum to post this thread.
I have downloaded peerunity_coin-control Pennybreaker compiled in http://www.peercointalk.org/index.php?topic=2648.75
-
unzip contents of peerunity_coin-control.zip in D:\bin
-
To run (on windows 7 professional) it I used this command
D:\bin\Peerunity_coin-control\peerunity_coin-control-qt -conf=D:\bin\Peerunity_coin-controlThe config file D:\bin\Peerunity_coin-control\ppcoin.conf has the following contents
datadir=D:\bin\Peerunity_coin-control
testnet=1
server=1
rpcuser=u
rpcpassword=x
daemon=1
genproclimit=2(Note for future upgrade: with 0.9.1 btc wallet, datadir must be specified in the command line, not in the config file)
- peerunity_coin-control started and started to sync with the network. “D:\bin\Peerunity_coin-control\testnet” subdirectory is created with downloaded block chain. There were only two nodes. It took about two hours to sync.
- In the debug window, Information tab, “On testnet” box is checked.
- I renamed the “Receive coins” tab I renamed the existing address msX75Fp5MRv52aNmjjjx4Jr55FNXUBRQic to “faucet”.
- On the testnet faucet page http://testnet.peercoinfaucet.com/ have 10 testnet PPC sent to the address above.
- In settings->options check “Display coin control features (expert only!)”.
- In the “Receive coins” tab I generate another address mwYYXeZkNY1f1hxCoCKqNQzLXmZdTpDmaX (named faucet2) and used the faucet to get another 10 testnet PPC in order to have coins received at different time. Unfortuantely the two sets of coins arrived at the same time.
- Try the step above again (from a different IP) and sucessfully received 10 testnet PPC at a different time. Address is "faucet3 mq3P59FHPs597JZmJDJFYRHUn1kNUKnzQM
- In command console enter
setgenerate trueand mined some testnet PPCs. However these coins were not used in the test because by the time the tests were done, the coins were still not matured.
The above starts peerunity_coin-control and prepares the coins for testing.
Now I follow the functions listed here for further testing.
- These pass OK (GUI only. Functions such as setting up a custom change address and check if it works not tested)

- The following are verified except I do not see “lock” and “unlock”
[ul][li]Context menu [list]Copy to clipboard (amount,label,address,transaction id,lock,unlock)[/list] [/li][/ul]
These labels are tested except I cannot verify priorities because I do not know how priority levels are assigned.
[ul][li]Labels at the top [list]Quantity: number of selected outputs Amount: sum of selected unspent outputs Fee: see "Calculation of fee and transaction size" below minus fee: simply the amount shown is "Selected" minus the amount shown in "Fee" Bytes: see "Calculation of fee and transaction size" below Priority: priority = coinage / transactionsize. coinage = value * confirmations. miners order transactions by priority when selecting which go into a block Low Output: "yes" if any recipient receives an amount < 0.01BTC Change: shows the change you get back [/list] [/li][/ul]Low Output is yes when the amount is less than 0.01 PPC.
- I cannot copy amount to clipboard by direct right clicking the labels
[ul][li]direct right click the labels for copy amount to clipboard [/li][/ul]
The following are verified except that “The amount exceeds your balance” is “Insufficient funds!”
[b]Selection[/b] In this version of coin control, all selected outputs are going into the transaction for sure!! Of course, if you select more than you actually send, the bitcoin core will send the rest back to you as change, just as normal. And of course, if you select less than you send you will get "The amount exceeds your balance". And as already mentioned, if none are selected, coin control is inactive, this means everything is just the same as without coin control.Fee
If the sum of selected outputs minus the amount you are going to send is smaller than the required fee, you will probably get
“The total exceeds your balance when the transaction fee is included”
This is because you didnt select enough outputs to pay the fee.
You always must select enough outputs, so that those outputs can pay the fee.
- I do not know how to independently calculate transaction size so I didn’t test transaction size calculation
- Peercoin has a fixed transaction fee so the part about fee and free transaction calculation shouldn’t apply.
[b]Calculation of fee and transaction size[/b] The fee is calculated according to the fee set in the Settings menu. The calculation assumes 2 outputs in total. One for the destination address and one for the change. The formula is nBytesOutputs + (2 * 34) + 10. nBytesOutputs is the sum of selected outputs, 148 or 180 bytes per output, depending if compressed public key. Due to the inner workings of bitcoin the size per output is actually +/- 1 byte. Meaning the shown calculation is not always 100% correct. If you send exactly "selected minus fee" then you will not have change (1 output only). The transaction will then be 34 bytes smaller as what was calculated before.Free Transactions
In order to be able to send a free transaction, you need to follow the rules:
- transaction size must be < 10000 bytes
- priority must be at least “medium”
- any recipient must receive at least 0.01BTC
- change must be either zero or at least 0.01BTC
If you violate one rule you will see a min-fee and also the labels turn red:
Bytes.Priority,Low Output,Change. Depending which rule you violated.
Those 4 labels also have tool tips explaining this.
Also remember that violating one of the first 2 rules means 0.0005 PER kilobyte min-fee,
while violating one of the last 2 means 0.0005 min-fee only.
Summary
The coin control implmented in peerunity_coin-control passed tests of all main function items specified by cozz. Three minor items did not pass test and are marked in red above. One untested item is marked in blue.
Good job glv!
