So , should I always add the option --mine? #19
wouldn't the following line of code in slockdao.sol result in slockit receiving nothing?
basically totalWeiRecieved would be set to 0 the first time the function containing this line is called.
resulting in msg.sender receiving nothing. I am confused about the if statement. I assume that it would return true. either way msg.sender.send() is executed before totalWeiRecieved is set.
after which totalweirecieved is set to the balance of the contract.
the result being that slock doesn't receive the crowdfunded money.
Is my reasoning correct?
function finalize() external
{
if (now > closingTime && msg.sender == 0x510c && totalWeiReceived == 0 && this.balance >= minValue)
{
if (msg.sender.send(totalWeiReceived)) totalWeiReceived = this.balance;
}
}
Hi. Minor change that will help dapps recreate state of the token fully using only events.
do a call to the master contract to check permissions
which can be called instead of checking the storage value for owner.
Take #1 into account.
I believe that a malicious user could utilize the transfer functionality in line 100 of Token.sol to transfer their tokens to another account after they have voted once.
Since function vote line 201 or DAO.sol prevents a double vote by checking a list of voters for msg.sender the new owner with a different address could vote again.
This could allow a malicious user to have potentially infinite votes on any proposal.
allowing a user to rent the slock for a fixed time period
rent(uint startTime, uint length)checkAvailibility(uint startTime, uint length)
