* Update ReentrancyGuard for Istanbul Hard Fork
Changes:
Added L37, `_guardCounter = 1;`
Rationale:
The planned _Istanbul Hard Fork_ will implement [EIP 2200](e4d4ea348e/EIPS/eip-2200.md), which implements "net gas metering" for `sstore` operations. If the final value of `_guardCounter` is unchanged relative to the original value of it, a gas refund will be applied and charges for changing the value of `_guardCounter` will effectively not exist. This ends up being cheaper than the current implementation ONLY AFTER Istanbul. Before Istanbul, the added line actually ends up costing more gas.
Note that if `_guardCounter` is `0` initially, the initial cost and subsequent refund will both be larger than if `_guardCounter` is `1` initially. Although in both cases, the net gas cost (`gasCost - gasRefund`) are equal, it's better in terms of cost to have both the gas cost and refund smaller, as there is some limit to the percentage of a gas refund that can actually be realized.
* Update CHANGELOG.md
Added note for change to ReentrancyGuard.sol
* Update ReentrancyGuard.sol
* Update CHANGELOG.md
* Using extcodehash instead of extcodesize for less gas
`extcodehash` uses less gas then `extcodesize`. You can tell which address is a contract by the hash (see EIP-1052).
* Fix
* Add explainer
* Update Address.sol
* add changelog entry
* Updated code style to no more than120 characters per line.
* Unify code comments style with Doxygen-style tags.
* Fix the conflicts.
* Add a return value in the contract ERC20Burnable.
* A Add a wrapper function to change type of address to address payable.
* U Modify Address utils.
* A Add test case for Address.
* U Modify code style in ERC20Burnable.
* Add changelog entry.
* Improved dev docs.
* Add IntelliJ IDE config to .gitignore
* Fix variable name in ERC20 function comments
* Fix typos in Arrays function comment
* Fix typos in ownership test names
* Fix typo in Pausable test name
* Fix grammar in Ownable function comment
* Fix grammar in Crowdsale contract comment
* Fix typo in Counters contract comment
* Fix typo in ERC721Enumerable comment
* Fix typo in ERC721PausedToken test name
* Fix typo in Crowdsale function comment
* Fix typo in IncreasingPriceCrowdsale function comment
* Fix grammar in IncreasingPriceCrowdsale test name
* Fix typo in AllowanceCrowdsale test name
* Fix typo in RefundEscrow function comment
* Fix typo in ERC20Migrator contract comment
* Fix typos in SignatureBouncer comments
* Fix typo in SignedSafeMath test name
* Fix typo in TokenVesting contract comment
* Move Ownable comment from @notice section to @dev
The Ownable contract has a comment explaining that renouncing
ownership will prevent execution of functions with the onlyOwner
modifier.
This commit moves that comment to the @dev section and replaces it
with a description suitable for a generic user.
* Clarify purpose of ERC20 transfer function
* Clarify registration of ERC721Enumerable interface
* Clarify purpose of AllowanceCrowdsale test
* Increase specificity of inheritance comments
FinalizableCrowdsale and RefundableCrowsale both have comments
indicating that they are extensions of the Crowdsale contract.
This commit refines those comments to the most immediate ancestor
( TimedCrowdsale and RefundableCrowdsale respectively )
* Remove unused parameter in PaymentSplitter test
* Rename parameter in SignatureBouncer functions
The SignatureBouncer contract has modifiers to validate the
message sender is authorised to perform an action. They pass
msg.sender to internal functions as the variable `account`, but
the function comments refer to the variable as `sender`
This commit changes the variable name to `sender`
* Clarify comments in SignatureBouncer functions
The SignatureBouncer has comments that use the description
`sender` to refer to the variable `account`.
This commit updates the comments for consistency.
Maintainer Note: this reverts changes in the previous commit,
which renamed the variable `account` instead.
