* port statediff from 9b7fd9af80/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
* all: freezer style syncing
core, eth, les, light: clean up freezer relative APIs
core, eth, les, trie, ethdb, light: clean a bit
core, eth, les, light: add unit tests
core, light: rewrite setHead function
core, eth: fix downloader unit tests
core: add receipt chain insertion test
core: use constant instead of hardcoding table name
core: fix rollback
core: fix setHead
core/rawdb: remove canonical block first and then iterate side chain
core/rawdb, ethdb: add hasAncient interface
eth/downloader: calculate ancient limit via cht first
core, eth, ethdb: lots of fixes
* eth/downloader: print ancient disable log only for fast sync
* core, eth, trie: bloom filter for trie node dedup during fast sync
* eth/downloader, trie: address review comments
* core, ethdb, trie: restart fast-sync bloom construction now and again
* eth/downloader: initialize fast sync bloom on startup
* eth: reenable eth/62 until we properly remove it
This PR is a more advanced form of the dirty-to-clean cacher (#18995),
where we reuse previous database write batches as datasets to uncache,
saving a dirty-trie-iteration and a dirty-trie-rlp-reencoding per block.
The current trie memory database/cache that we do pruning on stores
trie nodes as binary rlp encoded blobs, and also stores the node
relationships/references for GC purposes. However, most of the trie
nodes (everything apart from a value node) is in essence just a
collection of references.
This PR switches out the RLP encoded trie blobs with the
collapsed-but-not-serialized trie nodes. This permits most of the
references to be recovered from within the node data structure,
avoiding the need to track them a second time (expensive memory wise).
This removes a golint warning: type name will be used as trie.TrieSync by
other packages, and that stutters; consider calling this Sync.
In hexToKeybytes len(hex) is even and (even+1)/2 == even/2, remove the +1.
