Paul Tsupikoff	b8a8a008ec	Make websocket optional for realtime fetcher (#1778) ... Realtime fetcher already uses both websocket and JSONRPC polling for more reliable new block fetching. Though, if no websocket was available, the realtime fetcher wouldn't start, and no new blocks arrived at all. As we already have a polling fallback, we now make websocket optional. This will also help with supporting nodes without websocket API. To disable websocket API, pass `nil` in `subscribe_named_arguments.transport`.	6 years ago

Paul Tsupikoff	ef1b0cd273	Describe indexer structure and list existing fetchers (#1763) ... * Describe indexer structure and list existing fetchers Resolves #1628. A brief description of indexer structure is added to `README.md` of `indexer` application. Installation instructions are removed, as they don't make sense for sub-app of umbrella application. * Add CHANGELOG.md entry	6 years ago

Paul Tsupikoff	f02e2d8841	Remove internal tx and token balance fetching from realtime fetcher (#1724) ... Internal transactions and token balances are the slowest to fetch and import. We'd rather have almost instant import of almost all block-related info than frequent timeouts in realtime fetcher and handing blocks over to catchup fetcher which imports this data asynchronously anyway.	6 years ago

Paul Tsupikoff	c423a41e49	Flatten indexer module hierarchy and supervisor tree (#1718) ... * Add a defsupervisor macro with common supervisor functionality This macro allows removing more than a dozen of copy-pasted `supervisor.ex` modules. The `Indexer.Fetcher` module will be expanded with even more common fetcher functionality in upcoming PRs. * Flatten indexer module hierarchy and remove generated supervisors Modules are organized into 3 directories: `fetcher`, `transform` and `temporary`. Supervisors are replaced with `use Indexer.Fetcher` clause. `token_balances.ex` and block fetchers are left as-is for now, as they require more invasive code refactoring, which will be done in upcoming PRs. * Flatten supervisor tree There is no need in separate `Block.Supervisor` hierarchy, so its children are placed in the root supervisor tree. The tree itself is moved to `Indexer.Supervisor` module to reduce amount of directories. * Add CHANGELOG.md entry	6 years ago

goodsoft	6450c3ac61	Discard child block with parent_hash not matching hash of imported block ... Consider a root block `A`, old chain `-- B -- C` and new one `-- B' -- C'`. Due to asynchronous nature of realtime fetcher it is possible for block `B` to be imported _later_ than the entire chain `-- B' -- C'`. In this case we should discard block `C'` and let it be refetched. When that happens, block `B` gets discarded to make sure block `B'` gets eventually fetched and the chain becomes consistent.	6 years ago

goodsoft	e1d13a3d7f	Force consensus loss for parent block if its hash mismatches parent_hash ... Fixes #1644 When reorg occurs and the older of new blocks fails to be imported, the old consensus block remains in the database. Catchup fetcher ignores it, and we get a discontinuity in the main chain. This commit adds an additional consensus loss step during block import: the parent block with hash not matching parent_hash of current block is marked non-consensus, thus creating a hole in main chain, forcing catchup fetcher to retry fetching it.	6 years ago

goodsoft	ea7d0d007f	Optimize token holder count updates when importing address current balances ... Problem: realtime fetcher transactions takes too long and often fails with a timeout. The reason of timeout is deleted_address_current_token_balances step of import, which selects previous balances for the rows we are going to update. The SELECT query it makes is extremely slow. Solution: we incorporate fetching old balance value into the upsert itself. This is done by help of a transient old_value field, which is updated in ON CONFLICT clause of INSERT with the previous value and returned.

goodsoft	8cbafd2ced	Set internal_transactions_indexed_at for empty blocks ... As there exist blocks without transactions we now pass the list of blocks to import routine instead of deriving this list from the list of fetched internal transactions.	6 years ago
