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	20f50d0dd4	Token holder_count ... `Token` `holder_count` stores `Explorer.Chain.count_token_holders_from_token_hash`, so it does not need to be recalculate for all runs. The `holder_count` is `nil` and must be initialized with a data migration. Since we know `count_token_holders_from_token_hash` across all tokens takes ~90 minutes the `token.holder_count` will be checked first, but if it is `nil`, `count_token_holders_from_token_hash` will still be called, which means the code can be deployed and the data migrations run in the background without blocking further deploys.	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	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.
