pasqu4le	e8c2fa554e	Allow Realtime Fetcher to wait for small skips ... Problem: Sometimes the realtime fetcher's `newHeads` websocket subscription skips a small amount of block numbers, just to be followed by those very same numbers that were skipped, without repeating the number that caused the skipping. This may be cause by out-of-order events or be a legitimate reorg, but in any case this causes close-in-time refetching which in turn leads to async insertions problems. Solution: allow the Realtime fetcher to keep track of a small (settable) skip and wait for the block number inside the skip to arrive before fetching the whole window. Obviously if it gets notified of the blocks following the skip (or it is forced into polling) the whole window gets fetched and inserted.	5 years ago

Ayrat Badykov	483beaa10d	do not fetch token instances with errors	5 years ago
pasqu4le	f04052c4c4	Remove nonconsensus blocks from cache after internal transactions importing ... Problem: after PR #2726 some blocks may lose consensus after internal transactions are imported. The cache is not aware of this and may hold outdated values. Solution: notify the cache to drop the blocks that lost consensus in such cases.	5 years ago

Ayrat Badykov	d34275d2fe	on-fly fetching of token instances ... Currently, we have to restart indexer to fetch metadata for newly imported ERC-721 token instances. This PR triggers fetching of new token instances after blocks imports in Catchup and Realtime fetchers.	5 years ago

pasqu4le	a8cd5058cf	Enforce DB transaction's order to prevent deadlocks ... Problem: due to the ShareLock mechanism used by PostgreSQL when there are several DB transactions are acting on multiple rows of the same table, it's possible to incur in a deadlock and so into an error. Solution: enforce a consistent order of ShareLock acquisition in all the relevant transaction. Also add clear documentation that should help in the future.	5 years ago

pasqu4le	3f30610dde	Add generic Map-like Cache behaviour and implementation ... Problem: multiple caches exist that contain some data as a map (key-value storing). More are to be implemented, so it would be good to abstract their implementation. Solution: add a behaviour and a macro (providing an implementation) to create this type of caches. At the same time, where possible: - redefine the existing ones using the new macro - optimize the implementation	5 years ago
Ayrat Badykov	0e736637a7	skip cache update if there are no blocks inserted ... Sometimes due to some error (mostly network) if may not fetch any data when indexing block. If block cache update is triggered it fails. This PR check if list is passed to cache update function.	5 years ago
pasqu4le	b52d10b22a	Add generic Ordered Cache behaviour and implementation ... Problem: multiple caches exist to keep a page of the most recent `n` elements. More are to be implemented, so it would be good to abstract their implementation. Solution: add a behaviour and a macro (providing an implementation) to create this type of caches. Redefine the existing ones using the new macro.	5 years ago

pasqu4le	da775b07b7	Group Explorer caches ... Problem: a bunch of different caches are under the Explorer.Chain namespaces, cluttering the codebase Solution: create a subdirectory and collect them all under the Explorer.Chain.Cache namespace	5 years ago
pasqu4le	54a1010a11	Improve Address controllers ... This is yet another step in checking controllers for improvements. In particular this time Address controllers were checked and this (mostly refactoring) changes were made: - a few calls to `Explorer.Chain.hash_to_address` were modified to avoid useless preloads where possible - `Explorer.Chain.find_or_insert_address_from_hash` was modified for the very same reason, because it calls the previous function - `Explorer.Chain.address_to_logs` has been modified to have a more legible where clause - both `Explorer.Chain.hash_to_address` and `Explorer.Chain.token_from_address_hash` were modified to support `necessity_by_association_option`s for consistency	5 years ago
Victor Baranov	9bbec7b2cd	Remove changes, that fixed on Nethermind side	5 years ago
pasqu4le	bef66e846f	Add transactions cache ... Problem: due to the unsatisfying performance of the main page some ETS-based cache has been deemed necessary. In this particular case one for the most recent collated transactions. Solution: implementation of said transactions cache	5 years ago
pasqu4le	144f39db5b	Remove duplicate params in `Indexer.Fetcher.TokenBalance` ... Problem: `Explorer.Chain.Import.Runner.Address.TokenBalances` fails with the `cardinality_violation` error because it tries to insert more than once token balances (for the same {token_contract_address_hash, address_hash, block_number} tuple) in a single database transaction. Solution: filter out duplicate parameters in `Indexer.Fetcher.TokenBalance` so that no duplicates are sent to be imported.	6 years ago
