Luke Imhoff	4556ee2c01	Fix tests of transactions on non-consensus blocks ... Tests for BlockTransactionController mistakenly simulated transactions on non-consensus blocks by making the `transaction.block` `consensus` `false`, but this is unrealistic - the importing only sets the consensus block to `transaction.block` and non-consensus blocks show up as `transaction.transaction_forks` `transaction_fork.uncle`. To prevent this from happening again, `Explorer.Factory.with_block` now checks the `block` has `consensus: true`. With this setup fixed, the tests needed to be updated to show that *no* _transactions_ would be shown for non-consensus blocks (because there are only transactions forks) and whether the non-consensus blocks showed as "above tip" only had to do with the number being above the consensus number and not to do with it being non-consensus. Floki selectors are used to improve error messages when messages are unexpected.	6 years ago
Luke Imhoff	57808d6b23	Separate usage of max consensus block number and block height ... The block height should be used when calculating confirmations while the max consensus block number when a block number is needed and you want to tell if the chain is empty or only the genesis block is available. The block height is 0 if there are no blocks or if there is only the genesis block.	6 years ago
Luke Imhoff	cb7bc384e8	Calculate indexed ratio in SQL ... By calculating the indexed ratio in SQL, we only have 1 round trip to the database instead of 1 to get the max and 1 to get the min.	6 years ago
Luke Imhoff	083e5d3278	Ensure min and max block number is for consensus blocks ... Adding `WHERE consensus = true` both fixes the bug that `min_block_number` and `max_block_number` were including non-consensus blocks, but it also makes the query faster because there is an index for consensus blocks.

Luke Imhoff	a571a4edb3	Don't fetch or import internal transactions for value transfers ... Fixes #1287 For simple value transfers, the UI already doesn't show the redundant single internal transaction, but we can speed up the indexing by determine the internal transactions aren't needed when the transacion is a successful simple value transfer as determined by status being `:ok` and the input being empty (`0x`).	6 years ago

Luke Imhoff	8ffbe6418d	Use COUNT(*) of current_token_balances to eliminate TokenHoldersCounter ... `TokenHolderCounter` was created 20 days before the current_token_balances table and wasn't redesigned to make use of `current_token_balances`. With `current_token_balances` in place, the problematic query over `token_balances` that necessitated `TokenHoldersCounter` can use `current_token_balances`. Using `current_token_balances` with `COUNT(*)` is when tested on eth60-test, the new query for `Explorer.Chain.count_token_holders_from_token_hash/1` still took 11 seconds. ``` sql> SELECT COUNT(*) FROM address_current_token_balances WHERE token_contract_address_hash = decode('f230b790e05390fc8295f4d3f60332c93bed42e2', 'hex') AND address_hash != decode('0000000000000000000000000000000000000000', 'hex') AND value > 0 [2019-01-02 08:04:26] 1 row retrieved starting from 1 in 11 s 554 ms (execution: 11 s 463 ms, fetching: 91 ms) ``` Using `EXPLAIN`, it should this was using a full sequential scan of table, so like in the other `COUNT(*)` optimizations PRs, I added an index to enable an index scan. Running the migration to add the index took only 1 minute on eth60-test: ``` 2019-01-02T08:40:16.220 application=ecto_sql [info] == Running 20190102141900 Explorer.Repo.Migrations.IndexCurrentTokenHolders.change/0 forward 2019-01-02T08:40:16.220 application=ecto_sql [info] create index address_current_token_balances_token_contract_address_hash_index 2019-01-02T08:41:13.746 application=ecto_sql [info] == Migrated 20190102141900 in 57.5s ``` After the migration ran, Index Scan was enabled and the query took only 837ms. ``` sql> SELECT COUNT(*) FROM address_current_token_balances WHERE token_contract_address_hash = decode('f230b790e05390fc8295f4d3f60332c93bed42e2', 'hex') AND address_hash != decode('0000000000000000000000000000000000000000', 'hex') AND value > 0 [2019-01-02 08:42:44] 1 row retrieved starting from 1 in 866 ms (execution: 837 ms, fetching: 29 ms) ```	6 years ago

Luke Imhoff	2ec9600a61	Only query for coin balance when channel connected ... Normally, it is good idea to only query the database once no matter the number of sockets for a channel, but most addresses don't have listeners, so it is cheaper to not query unless the channel is in use. If we start to see popular addresses, con_cache can be used to only do the query once across all connected sockets for the same address.

Sebastian Abondano	fa09f399d8	GraphQL API token_transfers query ... Why: * For GraphQL API users to be able to fetch token transfer events. RPC API users could use this instead of the `tokentx` RPC API action. Example usage: 1. ``` query ($token_contract_address_hash: AddressHash!, $first: Int!) { token_transfers(token_contract_address_hash: $token_contract_address_hash, first: $first) { edges { node { amount block_number log_index token_id from_address_hash to_address_hash token_contract_address_hash transaction_hash } } } } ``` 2. with pagination support via [Relay Cursor Connections](https://facebook.github.io/relay/graphql/connections.htm) ``` query ($token_contract_address_hash: AddressHash!, $first: Int!, $after: ID!) { token_transfers(token_contract_address_hash: $token_contract_address_hash, first: $first, after: $after) { page_info { has_next_page has_previous_page } edges { node { amount from_address_hash to_address_hash } cursor } } } ``` * Issue link: n/a This change addresses the need by: * Editing the node interface and node field in `BlockScoutWeb.Schema` to support token transfers. * Adding `token_transfers` connection field to root query object in `BlockScoutWeb.Schema` * Making `token_transfer` object types a node type and adding a few new fields to it, in `BlockScoutWeb.Schema.Types`. * Creating `BlockScoutWeb.Resolvers.TokenTransfer` with resolver functions for getting token transfers. * Adding `get_token_transfer/1` and `list_token_transfers_query/1` to `Explorer.GraphQL`. These two functions are used by the new resolver functions mentioned above. * Editing RPC API docs to reference the new GraphQL query field added in this commit.	6 years ago
Sebastian Abondano	e7071172e2	Allows other sites to open blockscout in iframe ... Why: * For our partners to be able to open BlockScout in an iframe. * Issue link: n/ah This change addresses the need by: * Creating `AllowIframe` plug. * Editing router to have a new scope for write-only routes and a separate one for read-only routes which allows for iframes (using the plug mentioned above).	6 years ago

Why: * For our partner's front-ends to be able to work with our API endpoints. * Issue link: https://github.com/poanetwork/blockscout/issues/1011 This change addresses the need by: * Adding `CORSPlug` with defaults plus `x-apollo-tracing` header for GraphQL usage with graphqlbin.com	6 years ago
Sebastian Abondano	24079bb741	GraphQL support to get internal transactions ... Why: * For GraphQL API users to be able to get internal transactions. RPC API users could use this instead of the `txlistinternal` RPC API action. Example usage: 1. ``` query ($hash: FullHash!, $first: Int!) { transaction(hash: $hash) { internal_transactions(first: $first) { edges { node { index value block_number transaction_index from_address_hash to_address_hash } } } } } ``` 2. with pagiantion support via [Relay Cursor Connections](https://facebook.github.io/relay/graphql/connections.htm) ``` query ($hash: AddressHash!, $first: Int!, $after: ID!) { transaction(hash: $hash) { internal_transactions(first: $first, after: $after) { page_info { has_next_page has_previous_page } edges { node { index transaction_hash } cursor } } } } ``` * Issue link: n/a This change addresses the need by: * Editing the node interface and node field in `BlockScoutWeb.Schema` to support internal transactions. * Adding `internal_transaction` object type to `BlockScoutWeb.Schema.Types`. * Adding an `internal_transaction` connection field to the `transaction` object type in `BlockScoutWeb.Schema.Types`. * Adding `:call_type` and `:type` enums to `BlockScoutWEb.Schema.Scalars`. Needed by `internal_transaction` GraphQL object type. * Creating `BlockScoutWeb.Resolvers.InternalTransaction` with resolver functions for getting internal transactions. * Adding `get_internal_transactions/1` and `transaction_to_internal_transactions_query/1` to `Explorer.GraphQL`. These are used by the new resolver functions mentioned above.	6 years ago
