5307de2b97 modify go-etheruem vendor lib with methods that allow for unpacking of events into maps of interfaces 2018-11-03 14:01:41 -05:00
Ian Norden
8ce75fe5ad Generic watcher that takes a contract address, grabs the contract abi and starting block number, creates custom event filters, and extracts and transforms event data into postgres. Can configure to look at only a subset of events through CLI flag. Building but needs testing. 2018-11-03 14:00:25 -05:00
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

44177e0772 reorganizing contract-specific modules into event_triggered contract directories 2018-11-03 13:49:23 -05:00

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

4aa403d90d event_triggered transformer, transformer tests, and integrations tests for Transfer and Approval events 2018-11-03 13:49:23 -05:00

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

ada872404e Transfer and Approval event repo and repo tests + db migrations for these events. 2018-11-03 13:49:23 -05:00

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

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
1d50a0ace0 fixed tests for getting balanceOf and allowance, added balanceOf and allowance to the repo and repo tests and updated sql schema with new token_balance and token_allowance tables to accept this data 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

99e549b3df changes to repo and repo tests so that supply table is organized and accessed by token_address 2018-11-03 13:49:23 -05:00

bea712ba10 fetcher tests for FetchBool and FetchAddress 2018-11-03 13:49:23 -05:00
Ian Norden
ccd21f73c9 adjusted FetchContractData to work with variable number of contract method arguments, changed fetcher's FetchSupply method to more general FetchBigInt method and added FetchBool and FetchAddress methods 2018-11-03 13:49:23 -05:00

93960e7c4e Add several improvements to README.md (#28) 
- Expand instructions around technical specifics of project
  setup, including special gotchas in Ubuntu-based
  environments
- Add statement of setup flow to give thousand-foot view to
  users setting up Vulcanize for the first time

ba071ef13f Consolidate test doubles 
- Migrate various mocks of core namespaces to shared version in `fakes` pkg
- Err on the side of making test doubles less sophisticated
- Don't pull over mocks of namespaces that are only used in example code

05186634bd Add light sync command 
- Only syncs block headers (excludes block bodies, transactions, receipts, and logs)
- Modifies validation window to include the most recent block
- Isolates validation window to the variable defined in the cmd directory (blocks
  have a separate variable defined in the block_repository for determining when
  to set a block as final)

b6f93e735f Add ERC20 token watcher example 
- starting with the totalSupply function
- sets contract config on transformer by passing it into the transformer
initializer
- handles block records with the same number for different nodes for both creating token_supply records, and finding missing blocks

b1df139d29 Merge pull request #57 from vulcanize/fix-missing-blocks-lookup 
Fix missing block numbers lookup
 2018-06-13 11:28:22 -05:00
Rob Mulholand
3e39ccb9bb Fix missing block numbers lookup 
- Previously, a block was treated as missing if there was a number in
the given range for which there existing a block that did not match
the node's fingerprint. This meant that in a case where we have a block
that does not match the node's fingerprint and also one that does match,
the block would be treated as missing. This led to errors being thrown
when attempting to add a block that already exists.
- These changes treat a block as missing only if we do not already have
a block that matches the number and node fingerprint.

462f94d84a Associate receipts with blocks instead of transactions 
- Allows us to fetch receipts by block and persist even when
associated transaction is unknown. (The associated transaction
can still be derived from the tx_hash column at query time, but
is an expensive operation to require for inserts).
