I have this sample contract that I am trying to run. The function getvalues returns me correct values set earlier, when the setvalues function was written to set 2 values. when i modified the contract to set & return 3 values instead of 2, contract was mined successfully, but getvalues function returns only zeros.

Sample run:

sampcont2.setvalues(2500,100,120,130)
sampcont2.getvalues(2500)

output:

[0,0,0]

When the contract was written to set and return 2 values:

sampcont2.setvalues(2500,100,120)
sampcont2.getvalues(2500)

output:

[100,120]

Here is the contract that returns 3 values:

contract sampcont2{

    struct customer{
        uint custid;
        uint custvalue1;
        uint custvalue2;
        uint custvalue3;
        string comments;

    }

    mapping(uint => customer) customers;

      function setvalues(uint cid,uint a,uint b,uint c) {
        customers[cid].custid = cid;
        customers[cid].custvalue1 = a;
        customers[cid].custvalue2 = b;
        customers[cid].custvalue3 = c;

    }


    function getvalues(uint id) constant returns (uint x,uint y,uint z) {

         return (customers[id].custvalue1,customers[id].custvalue2,
         customers[id].custvalue3);
    }                
}

Edit: This is what I see:

So is it actually a gas problem?

  • I suggest trying with more gas. – kobigurk Sep 15 '16 at 9:36
  • thx , I will try that, but I am already using 4700000 in the contract, while the transaction and execution costs are as below: Transaction cost: 172257 gas. Execution cost: 92317 gas. – eNVy Sep 15 '16 at 9:40
  • I am using Broswer-solidity, i tried copying the text within Web3 deploy box, increased the gas amount there which was previously set to 4700000. however, anything greater than 4700000 throws an error : "Exceeds Block Gas Limit undefined" – eNVy Sep 15 '16 at 10:47
  • Can you confirm that your contract was deployed with eth.getCode(addressOfContract)? – Xavier Leprêtre B9lab Sep 15 '16 at 11:17
  • Yes Xavier, it did. I got the Bytecode. – eNVy Sep 15 '16 at 11:22

Yes it is a gas problem. Your setvalues(2500,100,120,130) transaction was sent with the default gas of 90,000. This transaction requires at least 102,768 gas.


Details Below

I'm testing out using the latest Solidity realtime compiler and geth 1.4.11-stable in local dev mode with the following command:

geth --datadir ~/EtherDev/data --dev --nodiscover --mine --minerthreads 1 --port 30301 --maxpeers 0 --verbosity 3 --unlock 0 --password ~/EtherDev/etc/passwordfile --rpc --rpccorsdomain '*' console

I deployed your contract as shown in the following screen:

enter image description here

I called setvalues(2500,100,120,130) as shown in the following screen:

enter image description here

You can see that 102,768 gas was used in sending the transaction.

And I queried getvalues(2500) as shown in the following screen:

enter image description here

  • I was hoping upgrading to latest geth would work, but looks like it doesn't help :( – eNVy Sep 20 '16 at 9:56
  • thx @BokkyPooBah , so I tried changing gaslimit with --targetgaslimit as well, but on trying to setvalues, i still get gas limit as 90000, how can i get around this? – eNVy Sep 26 '16 at 9:58
  • How are you deploying your contract, and how are you sending the transaction? Using geth command line? – Bokky WeAreAllAssange PooBah Sep 26 '16 at 10:00
  • Yes @BokkyPooBah – eNVy Sep 27 '16 at 8:12
  • The syntax is like c.stateChanger(3, {from:eth.accounts[0], gas: 400000}) from ethereum.stackexchange.com/questions/7557/… – Bokky WeAreAllAssange PooBah Sep 27 '16 at 8:41
