* Write state diff to CSV (#2) * port statediff from https://github.com/jpmorganchase/quorum/blob/9b7fd9af8082795eeeb6863d9746f12b82dd5078/statediff/statediff.go; minor fixes * integrating state diff extracting, building, and persisting into geth processes * work towards persisting created statediffs in ipfs; based off github.com/vulcanize/eth-block-extractor * Add a state diff service * Remove diff extractor from blockchain * Update imports * Move statediff on/off check to geth cmd config * Update starting state diff service * Add debugging logs for creating diff * Add statediff extractor and builder tests and small refactoring * Start to write statediff to a CSV * Restructure statediff directory * Pull CSV publishing methods into their own file * Reformatting due to go fmt * Add gomega to vendor dir * Remove testing focuses * Update statediff tests to use golang test pkg instead of ginkgo - builder_test - extractor_test - publisher_test * Use hexutil.Encode instead of deprecated common.ToHex * Remove OldValue from DiffBigInt and DiffUint64 fields * Update builder test * Remove old storage value from updated accounts * Remove old values from created/deleted accounts * Update publisher to account for only storing current account values * Update service loop and fetching previous block * Update testing - remove statediff ginkgo test suite file - move mocks to their own dir * Updates per go fmt * Updates to tests * Pass statediff mode and path in through cli * Return filename from publisher * Remove some duplication in builder * Remove code field from state diff output this is the contract byte code, and it can still be obtained by querying the db by the codeHash * Consolidate acct diff structs for updated & updated/deleted accts * Include block number in csv filename * Clean up error logging * Cleanup formatting, spelling, etc * Address PR comments * Add contract address and storage value to csv * Refactor accumulating account row in csv publisher * Add DiffStorage struct * Add storage key to csv * Address PR comments * Fix publisher to include rows for accounts that don't have store updates * Update builder test after merging in release/1.8 * Update test contract to include storage on contract intialization - so that we're able to test that storage diffing works for created and deleted accounts (not just updated accounts). * Factor out a common trie iterator method in builder * Apply goimports to statediff * Apply gosimple changes to statediff * Gracefully exit geth command(#4) * Statediff for full node (#6) * Open a trie from the in-memory database * Use a node's LeafKey as an identifier instead of the address It was proving difficult to find look the address up from a given path with a full node (sometimes the value wouldn't exist in the disk db). So, instead, for now we are using the node's LeafKey with is a Keccak256 hash of the address, so if we know the address we can figure out which LeafKey it matches up to. * Make sure that statediff has been processed before pruning * Use blockchain stateCache.OpenTrie for storage diffs * Clean up log lines and remove unnecessary fields from builder * Apply go fmt changes * Add a sleep to the blockchain test * Address PR comments * Address PR comments * refactoring/reorganizing packages * refactoring statediff builder and types and adjusted to relay proofs and paths (still need to make this optional) * refactoring state diff service and adding api which allows for streaming state diff payloads over an rpc websocket subscription * make proofs and paths optional + compress service loop into single for loop (may be missing something here) * option to process intermediate nodes * make state diff rlp serializable * cli parameter to limit statediffing to select account addresses + test * review fixes and fixes for issues ran into in integration * review fixes; proper method signature for api; adjust service so that statediff processing is halted/paused until there is at least one subscriber listening for the results * adjust buffering to improve stability; doc.go; fix notifier err handling * relay receipts with the rest of the data + review fixes/changes * rpc method to get statediff at specific block; requires archival node or the block be within the pruning range * review fixes * fixes after rebase * statediff verison meta * fix linter issues * include total difficulty to the payload * fix state diff builder: emit actual leaf nodes instead of value nodes; diff on the leaf not on the value; emit correct path for intermediate nodes * adjust statediff builder tests to changes and extend to test intermediate nodes; golint * add genesis block to test; handle block 0 in StateDiffAt * rlp files for mainnet blocks 0-3, for tests * builder test on mainnet blocks * common.BytesToHash(path) => crypto.Keaccak256(hash) in builder; BytesToHash produces same hash for e.g. []byte{} and []byte{\x00} - prefix \x00 steps are inconsequential to the hash result * complete tests for early mainnet blocks * diff type for representing deleted accounts * fix builder so that we handle account deletions properly and properly diff storage when an account is moved to a new path; update params * remove cli params; moving them to subscriber defined * remove unneeded bc methods * update service and api; statediffing params are now defined by user through api rather than by service provider by cli * update top level tests * add ability to watch specific storage slots (leaf keys) only * comments; explain logic * update mainnet blocks test * update api_test.go * storage leafkey filter test * cleanup chain maker * adjust chain maker for tests to add an empty account in block1 and switch to EIP-158 afterwards (now we just need to generate enough accounts until one causes the empty account to be touched and removed post-EIP-158 so we can simulate and test that process...); also added 2 new blocks where more contract storage is set and old slots are set to zero so they are removed so we can test that * found an account whose creation causes the empty account to be moved to a new path; this should count as 'touching; the empty account and cause it to be removed according to eip-158... but it doesn't * use new contract in unit tests that has self-destruct ability, so we can test eip-158 since simply moving an account to new path doesn't count as 'touchin' it * handle storage deletions * tests for eip-158 account removal and storage value deletions; there is one edge case left to test where we remove 1 account when only two exist such that the remaining account is moved up and replaces the root branch node * finish testing known edge cases * add endpoint to fetch all state and storage nodes at a given blockheight; useful for generating a recent atate cache/snapshot that we can diff forward from rather than needing to collect all diffs from genesis * test for state trie builder * minor changes/fixes * update version meta * if statediffing is on, lock tries in triedb until the statediffing service signals they are done using them * update version meta * fix mock blockchain; golint; bump patch * increase maxRequestContentLength; bump patch * log the sizes of the state objects we are sending * CI build (#20) * CI: run build on PR and on push to master * CI: debug building geth * CI: fix coping file * CI: fix coping file v2 * CI: temporary upload file to release asset * CI: get release upload_url by tag, upload asset to current relase * CI: fix tag name * fix ci build on statediff_at_anyblock-1.9.11 branch * fix publishing assets in release * bump version meta * use context deadline for timeout in eth_call * collect and emit codehash=>code mappings for state objects * subscription endpoint for retrieving all the codehash=>code mappings that exist at provided height * bump version meta * Implement WriteStateDiffAt * Writes state diffs directly to postgres * Adds CLI flags to configure PG * Refactors builder output with callbacks * Copies refactored postgres handling code from ipld-eth-indexer * rename PostgresCIDWriter.{index->upsert}* * less ambiguous * go.mod update * rm unused * cleanup * output code & codehash iteratively * had to rf some types for this * prometheus metrics output * duplicate recent eth-indexer changes * migrations and metrics... * [wip] prom.Init() here? another CLI flag? * cleanup * tidy & DRY * statediff WriteLoop service + CLI flag * [wip] update test mocks * todo - do something meaningful to test write loop * logging * use geth log * port tests to go testing * drop ginkgo/gomega * fix and cleanup tests * fail before defer statement * delete vendor/ dir * unused * bump version meta * fixes after rebase onto 1.9.23 * bump version meta * fix API registration * bump version meta * use golang 1.15.5 version (#34) * bump version meta;
