zachdaniel	5d12613f70	feat: support tracing via spandex	6 years ago
Luke Imhoff	3499155cdb	Partial retries for fetch_blocks_by_range ... Means that both Block.Fetchers, realtime and catchup, now handle fetch errors. The Block.Catchup.Fetcher will retry those blocks that failed to fetch while importing the rest that did fetch instead of refetching the whole batch.	6 years ago

svenski123	3b45474e36	Update address extraction testcases	6 years ago
svenski123	29199eb54e	Add nonce field to Address object and addresses table. ... This caches the highest nonce value seen for sent transactions for a given address. The top addresses query no longer needs to scan the transactions table for nonce values. The database migration script adds the nonce field to the addresses table and sets the nonce value according to the contents of the transactions table.	6 years ago

Felipe Renan	e2827ba907	Log token balances that raised errors	6 years ago
Felipe Renan	a79fa5b3e4	Add retry feature to the TokenBalance.Fetcher ... As some token balances always will raise errors interacting with the Smart Contract, we have to ignore them. Otherwise, we will accumulate a lot of toke balances in the indexer memory that never will be fetched.	6 years ago
Felipe Renan	10821e6b0b	Rename FunctionsReader to MetadaRetriever ... Also: * Renaming `fetch_functions_from_contract` to `fetch_functions_with_retries` * Using pattern matching instead of guard in `fetch_functions_with_retries`	6 years ago
Felipe Renan	477de645fb	Refactor Indexer.Token.Fetcher ... This refactor aims to remove the responsability of reading functions from the Smart Contract from Token.Fetcher. Now, we have the module Explorer.Token.FunctionsReader that is responsible for it.	6 years ago
Luke Imhoff	e4b7a4ee5f	Geth internal transactions ... Get internal transactions using debug_traceTransaction and a custom tracer. The tracer was based on the callTracer that ships with Geth, but rewritten to break it into more functions with more explicit purpose and to patch some holes in callTracer: * All calls have gas and gasUsed, which patches the hole in callTracer for handling `DELEGATECALL`. * All calls have value, which patches the hole in callTracer for handling `DELEGATECALL` and `STATICALL`. Since the tracer needed to be resubmitted in whole anyway, it was further customized to match the format needed for internal transactions: * Instead of returning the `op` as `type`, the `type` and `callType` used for internal transactions is returned. * Instead of returning a call tree, the tree is walked in pre-order, displaying the parent call before its nested calls to match the flat order returned from parity's trace_transaction.	6 years ago
Luke Imhoff	9cce7ab661	Adopt EIP-6 ... Geth has EIP-6, while Parity does not, but the Ethereum Yellow Paper includes EIP-6, so it is better to use EIP-6 when looking up community docs.	6 years ago

Gustavo Santos Ferreira	cf1be63b60	add new field to address extractor	6 years ago
Felipe Renan	5d1441d515	Do not store token_hash as address_hash in token balances ... We don't need this extraction because it will try to fetch the balance from the own token in its contract and it doesn't make sense for us. We will stop to store a lot of unnecessary data removing this extraction.	6 years ago

Luke Imhoff	91042f4af3	Shrinkable BufferedTasks ... `Indexer.BufferedTask` now uses an `Indexer.BoundQueue` instead of a `:queue`. All `Indexer.BufferedTask`s register with the memory monitor passed in to `BufferedTask.init/1` and will shrink their bound queue when asked. If they run out of work and have shrunk `c:init/2` will be called again on the callback module. `Indexer.Logger.process/1` will generate iodata of the pid and registered name of a process if available.	6 years ago

Luke Imhoff	9f09ee0226	Remove init_chunk_size ... It didn't really do much besides decided when to send GenServer.calls from the init_task.	6 years ago
Luke Imhoff	67ca25725d	Don't batch until run ... Instead of queuing up batches, store entries in queue and only form a batch when run is called. This ensures that the batch size is maximized and previously partial adjacent batches will go out as a full batch.	6 years ago
Luke Imhoff	7abc419617	Don't store pid in BufferedTask state	6 years ago
Luke Imhoff	b436d8bf5d	Don't track retry counts ... All implemented of BufferedTask ignore the number and not tracking it saves memory and simplifies BufferedTask itself.	6 years ago
Luke Imhoff	1fce095a35	Shrink Catchup Sequence if its consumes too much memory	6 years ago
Luke Imhoff	cae25195e5	Indexer.Memory.Monitor ... `Indexer.Memory.Monitor` checks if the BEAM memory usage exceeds a set limit (defaults to 1 GiB) and if it does, it asks the process with the most memory that is registered as shrinkable to shrink.	6 years ago
Amanda Sposito	b86335cf34	Add 'transaction_index' in the fetchers to save at 'internal_transaction' ... Add 'transaction_index' in the fetchers to save at 'internal_transaction'	6 years ago

Sebastian Abondano	2b8ceb4e32	Update block reward contract beneficiary balances ... Why: * "Parity’s consensus engine allows using a smart contract for block reward calculation." - see https://wiki.parity.io/Block-Reward-Contract for details. This means that we need to use `trace_block` (https://wiki.parity.io/JSONRPC-trace-module#trace_block) to fetch the block reward contract beneficiaries and update their balances. Currently this doesn't happen so there are addresses (block contract reward beneficiaries) with inaccurate balances and missing rows in the `address_coin_balances` table. * Issue link: https://github.com/poanetwork/blockscout/issues/767 This change addresses the need by: * Adding `EthereumJSONRPC.fetch_beneficiaries/2` to help us fetch the block reward contract beneficiaries of a given block range. This only works with Parity. * Editing Indexer's dev and prod config by adding `trace_block` config to `:method_to_url`. * Adding `block_reward_contract_beneficiaries` to `Indexer.AddressExtraction` for it to know how to get addresses in this scenario. * Editing `Indexer.Block.Fetcher.fetch_and_import_range/2` to get block reward contract beneficiaries, create their addresses if they don't yet exist, and update their coin balances.	6 years ago

Luke Imhoff	b1f4696569	Reconnect, rerequest, and resubscribe when websocket disconnects ... * Use struct, `%EthereumJSONRPC.WebSocket.WebSocketClient.Options{}` to hold `web_socket_options`. * `%EthereumJSONRPC.WebSocket.Registration{}` * Record `t:EthereumJSONRPC.request/0` in `%EthereumJSONRPC.WebSocket.Registration{}`, so that the request can be re-requested if the websocket disconnects and reconnects. * Drop server-side `subscription_id` from `%EthereumJSONRPC.WebSocket.Registration{}` as it can retrieved from `request` now. * `EthereumJSONRPC.WebSocket.WebSocketClient` * Track whether the web socket is connected or not, so that requests aren't sent when in the disconnected state. This prevents double-sends as `handle_call` can be called before `onconnect`, which caused that first subscribe to be sent twice. * Instead of the subscriber knowing the server-side subscription id, an opaque `t:reference/0` is used, so that the reference is stable in the subscriber's `%Subscription{}`, but the subscription ID can change on reconnect, which means replacing `subscription_id_to_subscription` in `%WebSocketClient{}` with 3 maps 1. `subscription_id_to_subscription_reference` - used translate server-side, per-connection subscription to the stable reference in `subscription_reference_to_subscription` 2. `subscription_reference_to_subscription_id` - used to convert stable reference to subscription id to unsubscribe. 3. `subscription_reference_to_subscription` - used to get full Subscription, including the subscriber_pid for when subscription messages are delivered or the subscription needs to be resubscribed using the `web_socket_options`. * `ondisconnect`, `:reconnect` immediately. * When disconnecting, tell unsubscribers they were successful. * Hold any json_rpc or subscribe requests to retry on reconnect. * Hold any subscriptions to resubscribe on reconnect. * `onconnect` * re-request the saved json_rpc and subscribe requests. * issue new requests to re-establish the subscriptions that had already succeeded in their subscribe requests. * `%EthereumJSONRPC.Subscription{}` * Replace `id`, which did match the server created ID, with a `t:reference/0`, which allows for indirection and for the server created ID to change on reconnect while the subscriber does not need to care about the reconnections. * `EthereumJSONRPC.WebSocket` * `options` is switched from a Keyword.t to a struct, `t`, so that it is easier to pattern match for the reconnect logic in `WebSocketClient`. * `web_socket_options` is no longer a generic `term` because the code did require it to be a map with a `:web_socket` key for the `t:GenServer.server/0`.	6 years ago
