Ian Norden	57820ff473	change transformer interface and watcher so that contract config is now fed into AddTransformers such that a single watcher can be loaded with transformers that use different cofigs	2018-11-03 13:49:24 -05:00
Ian Norden	44177e0772	reorganizing contract-specific modules into event_triggered contract directories	2018-11-03 13:49:23 -05:00
Ian Norden	d66e50dad6	Changes to address Rob's comments. Added generic/event_triggered transformer, tests, and repo migrations for Burn and Mint events	2018-11-03 13:49:23 -05:00
Ian Norden	aa2068bd08	adjust retriever to pull token holder addresses from Transfer and Approval events (iterating over Approvals might be redundant); edit Makefile to import new missing dependencies of go-ethereum/accounts/keystore, organizing mocks and adding event related mocks and filters	2018-11-03 13:49:23 -05:00
Ian Norden	55a73c5797	work on erc20 event_triggered functionality and generic helper for log unpacking and converting. helpers.ConvertToLog and helpers.createTopics have been adjusted to be variadic to work with event logs with any number of topics. Also uncovered issue with Dai and TrueUSD that means they doesn't really conform to the ERC20 standard. this is because they named their arguments to standard events like Approval and Trasnfer differently (e.g. Approval(src address, guy address, wad uint) and Approval(owner address, spender address, value uint) instead of the standard which is Approval(tokenOwner address, spender address, tokens uint)). This causes incompatibility with generic ERC20 entities and converters for these events.	2018-11-03 13:49:23 -05:00
Ian Norden	44e0a8d303	retriever for generating list of all token holder addresses + updated transformer to use said addresses to populate balanceOf and allowance information and added database migrations for balance and allowance tables	2018-11-03 13:49:23 -05:00
Ian Norden	9b41000b88	Moved fetcher to generic directory (methods have to remain public since it is in seperate package now), added FetchHash method, created ERC20 and generic getters which call the fetcher with specific contract methods (GetTotalSupply, GetBalance, GetAllowance for ERC20 getter, and GetOwner, GetStoppedStatus, GetStringName, GetHashName, GetStringSymbol, GetHashSymbol, and GetDecimals for generic getter). Getter tests cover all but GetBalance and GetAllowance, and also cover all of the Fetcher methods- but with only nil methodArgs. GetAllowance and GetBalance tests are not working against infura and these are the only contract method calls with arguments passed in so I suspect this might be where the issue lies. Have tested GetBalance using previous version of FetchContractData without the variadic input to the Pack method and it fails with the same error so I don’t think it is due to those changes.	2018-11-03 13:49:23 -05:00
