pasqu4le	e8c2fa554e	Allow Realtime Fetcher to wait for small skips ... Problem: Sometimes the realtime fetcher's `newHeads` websocket subscription skips a small amount of block numbers, just to be followed by those very same numbers that were skipped, without repeating the number that caused the skipping. This may be cause by out-of-order events or be a legitimate reorg, but in any case this causes close-in-time refetching which in turn leads to async insertions problems. Solution: allow the Realtime fetcher to keep track of a small (settable) skip and wait for the block number inside the skip to arrive before fetching the whole window. Obviously if it gets notified of the blocks following the skip (or it is forced into polling) the whole window gets fetched and inserted.	5 years ago

pasqu4le	144f39db5b	Remove duplicate params in `Indexer.Fetcher.TokenBalance` ... Problem: `Explorer.Chain.Import.Runner.Address.TokenBalances` fails with the `cardinality_violation` error because it tries to insert more than once token balances (for the same {token_contract_address_hash, address_hash, block_number} tuple) in a single database transaction. Solution: filter out duplicate parameters in `Indexer.Fetcher.TokenBalance` so that no duplicates are sent to be imported.	5 years ago

goodsoft	8e6ee4ceb1	Use eth_getUncleByBlockHashAndIndex for uncle block fetching ... Parity returns `null` for many uncle blocks, if they are fetched using `eth_getBlockByHash`. This is most probably caused by the fact that Parity only keeps full block data for recent non-consensus blocks. This causes uncle_block fetcher to loop endlessly trying to fetch "missing" blocks, hogging both app server and Parity resources. Instead, we use `eth_getUncleByBlockHashAndIndex` method, which works for all uncle blocks. As we didn't previously store index of an uncle block within a nephew block, a new field and a temporary fixup fetcher is added to get the index from nephew blocks.	6 years ago

Paul Tsupikoff	f02e2d8841	Remove internal tx and token balance fetching from realtime fetcher (#1724) ... Internal transactions and token balances are the slowest to fetch and import. We'd rather have almost instant import of almost all block-related info than frequent timeouts in realtime fetcher and handing blocks over to catchup fetcher which imports this data asynchronously anyway.	6 years ago
Paul Tsupikoff	c423a41e49	Flatten indexer module hierarchy and supervisor tree (#1718) ... * Add a defsupervisor macro with common supervisor functionality This macro allows removing more than a dozen of copy-pasted `supervisor.ex` modules. The `Indexer.Fetcher` module will be expanded with even more common fetcher functionality in upcoming PRs. * Flatten indexer module hierarchy and remove generated supervisors Modules are organized into 3 directories: `fetcher`, `transform` and `temporary`. Supervisors are replaced with `use Indexer.Fetcher` clause. `token_balances.ex` and block fetchers are left as-is for now, as they require more invasive code refactoring, which will be done in upcoming PRs. * Flatten supervisor tree There is no need in separate `Block.Supervisor` hierarchy, so its children are placed in the root supervisor tree. The tree itself is moved to `Indexer.Supervisor` module to reduce amount of directories. * Add CHANGELOG.md entry	6 years ago

goodsoft	0e15873fbc	Remove obsolete InvalidConsensus.Worker ... This worker only handled one of invalid consensus cases, i.e. when a parent block lost consensus, but the child one didn't. Even then it worked only when all blocks are reliably and sequentially imported (certainly not our case), and only once on indexer launch. Now this particular case is covered by previous commit, and we don't need this worker at all.	6 years ago

goodsoft	ea3af5e299	Use transaction-level fetch_internal_transactions for Geth ... Internal transaction fetcher is split into two APIs: * `fetch_block_internal_transactions` is used for Parity * `fetch_internal_transactions` is used for the rest of variants `Indexer.InternalTransaction.Fetcher` is updated to take care of that.	6 years ago

Paul Tsupikoff	2a8def19e2	Allow executing smart contract functions in arbitrarily sized batches ... # Problem There are a lot of `getBalanceOf` token function calls during indexing blockchain. Each of them is sent as a separate JSONRPC request, which creates a lot of unnecessary overhead and clogs archive node workers, which could otherwise be busy performing other JSONRPC queries. Moreover, function name is used as the `id` parameter of JSONRPC queries, which doesn't allow us to simply put multiple requests into one batch. # Solution * Change `EthereumJSONRPC.execute_contract_functions` to accept a list of arbitrary function calls and return a list of results. * Handle `id` field generation in the `EthereumJSONRPC` package instead of leaking implementation details to `Explorer.SmartContract.Reader`. * Change `Token.BalanceReader.get_balance_of` to accept a list of parameter sets and return a list of balances. * Make one batch request instead of launching multiple concurrent tasks in `Indexer.TokenBalances.fetch_token_balances_from_blockchain` # Notes * Protocol details of calling smart contract functions is now fully encapsulated in `EthereumJSONRPC` package. * `SmartContract.Reader.query_contract` is left for backwards compatibility with other existing applications of smart contract requests, but can be fully deprecated at some later time.	6 years ago
