zachdaniel	5582c3df1c	feat: synchronously fetch coin balances when an address is viewed. ... This is only done if the latest balance we have is as of a block that is older than approximately one day. We could just fetch a day old block and compare, but using the average_block_time lets us avoid hitting the database again, and also accounts for somehow having bad information in the blocks table, getting us the latest balance no matter what. If there is an unfetched coin balance, then we just fetch that instead of doing the above. We also don't render the balance if there is an unfetched row.	6 years ago

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	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	903d322553	Use index and COUNT(*) for address_to_validation_count ... BlockValidationCounter is not needed once the query is switched to `COUNT(*)` and an index is added for `blocks.miner_hash`. Creating the index on eth60-test took only 12 seconds. ``` 2018-12-21T08:32:46.375 application=ecto_sql [info] == Running 20181221143000 Explorer.Repo.Migrations.CreateBlocksMinerHashIndex.change/0 forward 2018-12-21T08:32:46.375 application=ecto_sql [info] create index blocks_miner_hash_index 2018-12-21T08:32:59.211 application=ecto_sql [info] == Migrated 20181221143000 in 12.8s ``` Before the index both `COUNT(*)` and `COUNT(hash)` (the old usage before 76fc8e0377 in 92f99cac22) take > 800ms, which would have a noticable impact on the UI. ``` sql> SELECT COUNT(*) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:27:43] 1 row retrieved starting from 1 in 906 ms (execution: 889 ms, fetching: 17 ms) sql> SELECT COUNT(hash) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:28:04] 1 row retrieved starting from 1 in 819 ms (execution: 811 ms, fetching: 8 ms) ``` After the index both queries benefited because `COUNT(hash)` was able to use Bitmap Index Scan, but `COUNT(*)` was much better using a normal Index Scan: ``` sql> SELECT COUNT(hash) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:33:43] 1 row retrieved starting from 1 in 776 ms (execution: 768 ms, fetching: 8 ms) sql> SELECT COUNT(*) FROM blocks WHERE blocks.miner_hash = ( SELECT blocks.miner_hash FROM blocks LIMIT 1 ) [2018-12-21 08:33:55] 1 row retrieved starting from 1 in 130 ms (execution: 120 ms, fetching: 10 ms) ``` The `SELECT` to get a miner_hash takes 54ms alone, so the `COUNT(*)` takes ~70ms, but EXPLAINs take just as long so ~50ms is my latency to eth60-test, meaning the `SELECT COUNT(*)` takes about 20ms plus latency.	6 years ago
Luke Imhoff	f67241cfc0	Use COUNT(*) for count_token_transfers_from_token_hash ... By using `COUNT(*)` instead of `COUNT(column)`, Postgres optimizes the count to use the row count recorded in the index. The ETS counter appeared necessary because in 95de1ebcb0, `COUNT(id)` was being used (95de1ebcb0/apps/explorer/lib/explorer/chain/token_transfer.ex (L138)), which seems reasonable in Ecto as you need some column to count, but in Postgres, it is more efficient to count everything with `*` as it implies "count rows". `COUNT(column)` requires Postgres check if any of the values are `NULL` and it does not optimize the query even if the column is `NOT NULL` in most cases like when the `id` was used. Testing on eth60-test database, `COUNT(*)` took 62ms while `COUNT(column)` (in this case `amount` since the table no longer has `id) took 16s demonstrating the vast speed improvement of `*` counting. ``` sql> SELECT COUNT(*) FROM token_transfers WHERE token_contract_address_hash = ( SELECT token_contract_address_hash FROM token_transfers LIMIT 1) [2018-12-21 07:51:02] 1 row retrieved starting from 1 in 70 ms (execution: 62 ms, fetching: 8 ms) sql> SELECT COUNT(amount) FROM token_transfers WHERE token_contract_address_hash = ( SELECT token_contract_address_hash FROM token_transfers LIMIT 1) [2018-12-21 07:51:43] 1 row retrieved starting from 1 in 16 s 862 ms (execution: 16 s 855 ms, fetching: 7 ms) ```	6 years ago

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	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
