aa4e698240 move interface_getter.go from ens_watcher to vDB pkging- used to construct a custom ABI based on results from calls to supportsInterface; also moved fetcher.go from examples to pkg 2019-01-15 15:49:18 -06:00

59cdaa05e6 moving some memory allocation to init function rather than within
execution cycles and fixing test db tear down so that it drops
checked_headers table instead of individual columns (droping columns
only hides them, they remain in memory and continue to contribute to the
1600 column limit which causes us to eventually exceed it)

d188329661 fetch event logs in batches- all events for a contract address at a given block height are fetched together, different contract events still fetched separately 2018-12-21 10:33:31 -06:00

e390a97502 finish method polling with hash or address type argument values
collected from watched events; 'MissingMethodsCheckedEventsIntersection'
method to find headers which have been checked for each event of
interest but methods have not yet been polled at that header; tests for
new features; travis ci go version 1.9 -> 1.11 ; consolidate omniWatcher and lightOmniWatcher into single command with light as default

0a59f06cac begin work on: Add checked_headers column for methods that are polled so taht we don’t duplicate; Add batching of method polling so that we arent generating a rediculously large account address list before using it to poll methods (or persist the list in pg?); User passed ABI and other ways to get ABI; Add ability to collect []byte and hashes from events and use them in method polling same manner as addresses; Event filter addrs => only those event’s addresses/hashes are used for polling; Option to persist seen address/hash/bytes lists into pg; Only generate lists of addresses, []byte, or hashes if a method will use them later 2018-12-21 10:33:31 -06:00

817bd76713 refactoring event converter and repository so that event logs are

417b18ec6a Edits to address PR issues; change license from apache to AGPL; and work
towards generic method polling and reposito;y; config settings to
filterevents/methods by account address; refactoring some stuff out of
repo and into converter; remove fetcher and instead call
blockchain's FetchContractData directly; finishing tests

b459cf35ed beginning work on method polling; first need to generate list of token holder address in a completely generic/contratc agnostic fashion. Created address retriever that can iterate through any given contract's watched events, finding the inputs/arguments with address type, and generate a list from those values. Edit: Contract objects now cache every event emitted address as its event logs are transformed into the repo to grow a list of contract associated addresses as we go 2018-11-04 21:37:31 -06:00

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

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
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

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)

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).
