Paul Tsupikoff	6a5916764d	Consolidate POSDAO contract reading (#2371 ) Previously, staking contract reading was arbitrarily spread across Explorer.Staking.ContractState, Explorer.Staking.PoolsReader and Indexer.Fetcher.StakingPools. Using async fetcher infrastructure for staking contracts is inadequate, as blocks may arrive out of order, while we want fetching to be triggered by newer block arrival. Also, contract calls were not batched enough, and it was hard to follow their sequence across involved modules. Now, on each incoming block, which is newer than the last seen, we fully update not only global contract state, but all validators, pools and delegators. All requests are intelligently compiled into four batches. These are defined together to give better overview of performed actions. Chain.import infrastructure is still used for inserting data into DB to leverage smart batching of INSERT queries. Likelihood calculation is added: it zips results of getPoolsToBeElected and getPoolsLikelihood calls to make a map of addresses. Only POS_STAKING_CONTRACT env variable is required now. Other contract addresses are fetched from it during launch. ABIs are concatenated together during launch as well, as we don't support batch requests against distinct ABIs yet. This should be addressed in further PRs. Up-to-date ABIs copied from build artifacts of posdao-contracts repo. File names now correspond to contract names, README directs to their origin. * Fetch inactive delegators, mark pools and delegators deleted (#2205) * Fetch min stakes and token contract address from StakingAuRa (#2313) * Fetch block reward ratio using validatorRewardPercent getter (#2424) * Add missing `banned_until` field in ON CONFLICT clause for staking pools.	4 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

Luke Imhoff	9a8cdc4031	Use Path.absname so that log paths are stable during reload Fixes #628 The Phoenix.CodeReloader causes the file loggers to restart and reload their config, but when they reload, the current working directory has shifted from the project root to the OTP app root, so it produces log files under each OTP app (`apps/APP_NAME/logs`). We don't want this, so compute the absolute path in the config files, so that the loaded `Application` environment has an absolute path in it that can't shift when the working directory changes.	6 years ago

Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` * `:error` is only for errors across all environments. It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/error.log`. * `:block_scout_web` is only when `:application` metadata is `:block_scout_web`. Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/block_scout_web.log`. * `:ethereum_jsonrpc` is only when `:application` metadata is `:ethereum_jsonrpc`.

Level is - `:debug` for `dev` - `:warn` for `test` - `:info` for `prod` It uses `LoggerFileBackend` and writes to `logs/<Mix.env>/explorer.log`. * `:indexer` is only when `:application` metadata is `:indexer`.
