Luke Imhoff	06475f1275	Don't broadcast from catchup ... Fixes rebase picking wrong version with broadcasting turned on for catchup index, which we don't want	6 years ago
Luke Imhoff	81ba3a5b7b	Only use address_hash_to_block_number if block_number is missing	6 years ago
Luke Imhoff	f2884992a7	Fetch realtime internal transactions and balances synchronously ... Fixes #366 Queuing the internal transactions and balances to be fetched asynchronously for realtime blocks lead to upto 15 minute delay between when a block appeared and the internal transaction was drained from the queue. It is a better user experience to not see the realtime blocks at all than to see them incomplete, so fetch the internal transactions and then the balances before importing the whole tree of data instead of using the catchup asynchronous queues.	6 years ago
Luke Imhoff	12f70945da	Switch Chain.import options to maps ... 1. Allows for easier composing with put_in than Keyword.t 2. Allows more precise specs as individal options can be marked as optional or required while the Keyword.t pattern makes it seem like everything is optional.	6 years ago
Luke Imhoff	68229420b4	Move Receipts functions out of BlockFetcher	6 years ago
Luke Imhoff	11735b1289	Separate Catch, Realtime, Supervisor, and BlockFetcher states ... BlockFetcher.Catchup and BlockFetcher.Realtime get their own structs, which use BlockFetcher struct. This better emphasizes that Catchup and Realtime are both block fetchers. The BlockFetcher.Catchup and BlockFetcher.Realtime structs move into Supervisor's struct.	6 years ago
Luke Imhoff	2333cc6cf5	Separate supervision and fetching parts of BlockFetcher ... Move supervision aspect to BlockFetcher.Supervisor and leave only the actual fetching code in BlockFetcher.	6 years ago
Luke Imhoff	e0fed23fad	Fix catchup_block_number not being set ... catchup_block_number can't be set in state because it is set in a separate task, so have the Task return it instead of storing it in a state field.	6 years ago
Luke Imhoff	807f5e6d7c	BlockFetcher.realtime_task -> BlockFetcher.Realtime.task	6 years ago
Luke Imhoff	2afa934225	BlockFetcher.catchup_task -> BlockFetcher.Catchup.task ... Move `catchup_task` out of `BlockFetcher`, so it is easier to spot catchup vs realtime vs common code.	6 years ago
Luke Imhoff	2f3af51741	Unified Explorer.Chain.import ... * Merge `Explorer.Chain.import_blocks` and `Explorer.Chain.import_internal_transactions` into `Explorer.Chain.import`. * Move body of `Explorer.Chain.import` and its private helper functions to `Explorer.Chain.Import` as an independent context that `Explorer.Chain` can use. `Explorer.Chain.Import` must be under `Explorer.Chain` because `Explorer.Chain.Import` still needs direct access to the `Explorer.Chain` schemas.	6 years ago
jimmay5469	e5e695331f	Subscribe to only realtime-indexer events for channel broadcasts	6 years ago
Luke Imhoff	9d66f4b84b	Handle result from realtime tasks ... Previously, BlockFetcher only had handle_info for the DOWN message from realtime tasks, but when the reason is :normal, the task would have succeeded and therefore, the BlockFetcher would also have received a `{ref, :ok}` that was not being matched.	6 years ago
Luke Imhoff	6abe66f7b1	Catch up index based on whether previous catch up found missing blocks ... When a catchup_index task completes without error, increase the interval until the next check by 2 if no blocks were missing and decrease it by 2 if blocks were missing. Minimum interval is the same as the realtime interval while the maximum interval is arbitarily chosen to be 10x the realtime interval.	6 years ago
Luke Imhoff	8f63f2a87c	Rename genesis task to catchup task ... It matches message (:catchup_index) used to trigger the task and reflects that the task to to catch-up the index to what the realtime task handles.	6 years ago
Luke Imhoff	b79d361909	Fix phrasing when genesis task completes	6 years ago
Luke Imhoff	d368159a09	Remove unused start_block_number in BlockFetcher state	6 years ago
Luke Imhoff	a6be2924b2	Running realtime task on interval ... Instead of scheduling the next realtime index in block_interval / 2 only after the previous one complete, run the realtime index every block_interval / 2 using `:timer.send_interval`. This ensures that the time it takes to complete the realtime index doesn't slowly build up, which is currently leading a missed block approximately every 15 blocks.	6 years ago
Luke Imhoff	3e09353d62	Fix typo	6 years ago
Luke Imhoff	f1e3c9e376	Use Task.Supervisor.async_nolink ... Task.Supervisor.async_nolink monitors the Task pid instead of linking, so it does the same thing as our Indexer.start_monitor.	6 years ago
Luke Imhoff	75e2bfccc0	realtime_interval -> block_interval / 2 ... The realtime_interval should be half of the block_interval to ensure that we don't get stuck in a state where we just miss a new block because using precisely the block rate doesn't account for processing time. The exact value of half the block_interval was chosen for the Nyquist rules.	6 years ago
Luke Imhoff	fe49a753d3	block_rate -> block_interval ... block_rate is measured in milliseconds / block, but a rate would blocks / unit-time, so rename block_rate to block_interval to reflect it is the interval between blocks.	6 years ago
Luke Imhoff	e3f7581572	Historical Address Balances	6 years ago
Luke Imhoff	3432fe4c51	Disable logging debug_count at regular intervals ... Fixes #422 BlockFetcher's debug_count support used the slow `Explorer.Chain.*_count` functions. We want those counts to be completely accurate when needed, so we can't move to the `Explorer.Chain.*_estimated_count`. Since, the current, accurate counts are slowing down the indexing by causing a timeout to have to be handled, completely remove the debug count support and have developers call the `Explorer.Chain.*_count` when they need them to monitor progress.	6 years ago
Luke Imhoff	5b01cd396b	Check that ranges are in same direction as step	6 years ago
Luke Imhoff	105ce9b613	Only allow positive step for infinite sequences	6 years ago
Luke Imhoff	94d8267799	Don't allow Sequence to be started with a mix of ranges and infinite start ... We either use Sequence with a fixed set of ranges in finite mode when getting the missing blocks down to genesis or in infinite mode when using it for the realtime index. We can't completely separate the support for queuing ranges for the realtime index as that handles retries, but we can simplify the validation considerably by disallowing ranges and first to `start_link`.	6 years ago
Luke Imhoff	c409d63720	Allow first to be 0 ... It can be `0` when in finite mode, so allow it to be set to `0` to indicate that ahead of time.	6 years ago
Luke Imhoff	ded84c9633	Cap genesis sequence immediately ... Genesis sequence should only fetch the missing ranges	6 years ago
Luke Imhoff	a3d51f5e1a	Raise error if `:first` would cause retraversal	6 years ago
Luke Imhoff	15be505219	Move range chunking from BlockFetcher to Sequence ... Ensures that all callers benefit from chunking bug fixes, not just BlockFetcher.	6 years ago

Felipe Renan	e6775ed987	Fix Indexer Supervisor three ... We are facing this error when starting the `Indexer`: ``` ** (EXIT) an exception was raised: ** (ArgumentError) :json_rpc_named_arguments must be provided to `Elixir.Indexer.InternalTransactionFetcher.child_spec to allow for json_rpc calls when running. ``` It was missing the `json_rpc_named_arguments` to InternalTransactionFetcher children.	6 years ago
Luke Imhoff	466c1e76f6	Request transport module and options for all JSONRPC calls ... To lessen load on Sokol chain nodes during testing and to allow substituting different transports than HTTP, such as IPC, in the future, pass the transport module and its options to any call to `EthereumJSONRPC.json_rpc`. This will allow us to use a `mox` module in local testing, so we only do true chain integration testing in CircleCI.	6 years ago

Luke Imhoff	5697cc7075	Fix {:error, :not_found} when starting indexer	6 years ago
Luke Imhoff	4ecfb3b409	CircleCI tests for Geth	6 years ago
Luke Imhoff	cac1cab39c	Geth receipts compatibility ... When testing transaction receipt processing using Geth against Ethereum Mainnet, a number of missing features were discovered: * Support for `to` and `from` addresses in receipts * The need to derive status for pre-Byzantium transactions by using the supplied gas from the transaction and the gasUsed in the receipt to check for out-of-gas.	6 years ago
Luke Imhoff	904a63b504	Explorer.Chain.Hash.Truncated -> Explorer.Chain.Hash.Address ... Blocks nonce will also be a type of hash, but it is only 8-bytes, instead of 20-bytes, so the general name "Truncated" will be confusing, so name it "Address" to be specific.	6 years ago
