* make StandardToken state variables private
* simplify mocks
* document new internal functions
* fix link to ERC20 document
* revert order of Transfer and Mint events
* Revert "simplify mocks"
This reverts commit 371fe3e567.
* add tests for new internal functions
* add check for null account
* add checks for balances and allowance
* add inline docs to BurnableToken._burn
* remove redundant checks and clarify why
* Consolidted ERC20 Interface and Implementation Files
* Fixed CanReclaimToken's tests to use StandardTokenMock instead of BasicTokenMock
* Changed token's variable type in TokenTimelock to ERC20
* Merged the StandardBurnableToken with BurnableToken since it now inherits from StandardToken; Fixed TokenTimelock so it uses SafeERC20 for ERC20
* Fixed variable type for _token in TokenTimelock constructor
* Fixed linting warning in BurnableToken
* Added back burnFrom tests.
* fixed visibility warnings
* solved visibility and line length warning
* change a test assertion that fails due to chai dependence update
* linter, constructor style and solved visibility warnings
* Changed Windows line endings to Unix.
* Update StandardToken.sol
* Slight improvement in gas efficiency
Users tend to attempt to over-spend more than they attempt to burn non-burnable tokens. If the contract checks for overspending before assuring tokens are not being burnt a slight amount of gas might be saved in the long term.
* Assume that token is mintable.
* ECRecover test should revert because of wrong calldata size
* fix: use expectThrow
* fix: ignore failing test until solc^0.5.0
* Added basic Escrow
* PullPayment now uses an Escrow, removing all trust from the contract
* Abstracted the Escrow tests to a behaviour
* Added ConditionalEscrow
* Added RefundableEscrow.
* RefundableCrowdsale now uses a RefundEscrow, removed RefundVault.
* Renaming after code review.
* Added log test helper.
* Now allowing empty deposits and withdrawals.
* Style fixes.
* Minor review comments.
* Add Deposited and Withdrawn events, removed Refunded
* The base Escrow is now Ownable, users of it (owners) must provide methods to access it.
* Align ERC721 Receiver with current ERC721 standard.
Adds a second address field to onERC721Received
onERC721Received(address,address,uint256,bytes)
Updates the function signature to 0x150b7a02 from 0xf0b9e5ba
* Add _operator to onERC721Received
* Fix error caused by formatOnSave
* Fixed comments on ERC721Receiver
Removed "Must use 50,000 gas or less"
Corrected the function signature
