* 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

This commit fixes a flaw in two testcases, and brings down the exec-time from ~40s to ~8s for trie/TestIncompleteSync.
The checkConsistency was performed over and over again on the complete set of nodes, not just the recently added, turning it into a quadratic runtime.

According to the benchmarks, type assertion between the pointer and
interface is extremely fast.
BenchmarkIntmethod-12 1000000000 1.91 ns/op
BenchmarkInterface-12 1000000000 2.13 ns/op
BenchmarkTypeSwitch-12 1000000000 1.81 ns/op
BenchmarkTypeAssertion-12 2000000000 1.78 ns/op
So the overhead for asserting whether the shortnode has "valuenode"
child is super tiny. No necessary to have another field.

This change introduces garbage collection for the light client. Historical
chain data is deleted periodically. If you want to disable the GC, use
the --light.nopruning flag.
* core, crypto: various allocation savings regarding tx handling
* core: reduce allocs for gas price comparison
This change reduces the allocations needed for comparing different transactions to each other.
A call to `tx.GasPrice()` copies the gas price as it has to be safe against modifications and
also needs to be threadsafe. For comparing and ordering different transactions we don't need
these guarantees
* core: added tx.GasPriceIntCmp for comparison without allocation
adds a method to remove unneeded allocation in comparison to tx.gasPrice
* core/types: pool legacykeccak256 objects in rlpHash
rlpHash is by far the most used function in core that allocates a legacyKeccak256 object on each call.
Since it is so widely used it makes sense to add pooling here so we relieve the GC.
On my machine these changes result in > 100 MILLION less allocations and > 30 GB less allocated memory.

When we flush a batch of trie nodes into database during the state
sync, we should guarantee that all children should be flushed before
parent.
Actually the trie nodes commit order is strict by: children -> parent.
But when we flush all ready nodes into db, we don't need the order
anymore since
(1) they are all ready nodes (no more dependency)
(2) underlying database provides write atomicity
