* core/vm/runtime: add test for blockhash
* core/evm: less iteration in blockhash
* core/vm/runtime: nitpickfix
Co-authored-by: Péter Szilágyi <peterke@gmail.com>
This change:
- removes the PostChainEvents method on core.BlockChain.
- sorts 'removed log' events by block number.
- fire the NewChainHead event if we inject a canonical block into the chain
even if the entire insertion is not successful.
- guarantees correct event ordering in all cases.
* core: s/isEIP155/isEIP2/ (fix)
This signature variable name reflects a spec'd change
in gas cost for creating contracts as documented in EIP2 (Homestead HF).
https://github.com/ethereum/EIPs/blob/master/EIPS/eip-2.md#specification
* core: s/isEIP2/sIsHomestead/g
Use isHomestead since Homestead is what the caller
and rest of the code uses.
* build: use golangci-lint
This changes build/ci.go to download and run golangci-lint instead
of gometalinter.

* core/vm: optimize mstore a bit
* core/vm: change Get -> GetCopy in vm memory access
* core/asm: Fix encoding of pushed labels
EVM uses big-endian byte-order, so to pad a label value to 4 bytes,
zeros must be added to the front, not the end.
* core/asm: Fix PC calculations when a label is pushed
Incrementing PC by 5 is only correct if the label appears after a jump,
in which case there is an implicit push. When it appears after an explicit
push, PC should only be incremented by 4.
* core/asm: Allow JUMP with no argument
This way, a label can be pushed explicitly, or loaded from memory to
implement a jump table.
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
The precompile at 0x09 wraps the BLAKE2b F compression function:
https://tools.ietf.org/html/rfc7693#section-3.2
The precompile requires 6 inputs tightly encoded, taking exactly 213
bytes, as explained below.
- `rounds` - the number of rounds - 32-bit unsigned big-endian word
- `h` - the state vector - 8 unsigned 64-bit little-endian words
- `m` - the message block vector - 16 unsigned 64-bit little-endian words
- `t_0, t_1` - offset counters - 2 unsigned 64-bit little-endian words
- `f` - the final block indicator flag - 8-bit word
[4 bytes for rounds][64 bytes for h][128 bytes for m][8 bytes for t_0]
[8 bytes for t_1][1 byte for f]
The boolean `f` parameter is considered as `true` if set to `1`.
The boolean `f` parameter is considered as `false` if set to `0`.
All other values yield an invalid encoding of `f` error.
The precompile should compute the F function as specified in the RFC
(https://tools.ietf.org/html/rfc7693#section-3.2) and return the updated
state vector `h` with unchanged encoding (little-endian).
See EIP-152 for details.
* graphql, internal/ethapi: extend eth_call
This PR offers the third option parameter for eth_call API.
Caller can specify a batch of contracts for overriding the
original account metadata(nonce, balance, code, state).
It has a few advantages:
* It's friendly for debugging
* It's can make on-chain contract lighter for getting rid of
state access functions
* core, internal: address comments
* params: add IsIstanbul to config + rules
IstanbulBlock, used to determine if the config IsIstanbul, is currently
left nil until an actual block is chosen.
* params, core/vm: implement EIP-1108
Old gas costs for elliptic curve operations are given the PreIstanbul
prefix, while current gas costs retain the unprefixed names. The actual
precompile implementations are the same, so they are factored out into
common functions that are called by the pre-Istanbul and current
precompile structs. Finally, an Istanbul precompile list is added that
references the new precompile structs, which in turn reference the new
gas costs.

* eth: chain config (genesis + fork) ENR entry
* core/forkid, eth: protocol independent fork ID, update to CRC32 spec
* core/forkid, eth: make forkid a struct, next uint64, enr struct, RLP

* eth: fix lint
* eth: fix crash in ethclient tests
This PR adds some hardening in the lower levels of the protocol stack, to bail early on invalid data. Primarily, attacks that this PR protects against are on the "annoyance"-level, which would otherwise write a couple of megabytes of data into the log output, which is a bit resource intensive.
This PR fixes an issue in chain indexer. Currently chain indexer will
validate whether the stored data is canonical by comparing section head
and canonical hash. But the header of the checkpoint may not exist in
the database. We should skip validation for sections below the
checkpoint.
* core/state, cmd/geth: streaming json output dump cmd + optional code+storage
* dump: add option to continue even if preimages are missing
* core, evm: lint nits
* cmd: use local flags for dump, omit empty code/storage
* core/state: fix state dump test
* core: move TxPool reorg and events to background goroutine
This change moves internal queue re-shuffling work in TxPool to a
background goroutine, TxPool.runReorg. Requests to execute runReorg are
accumulated by the new scheduleReorgLoop. The new loop also accumulates
transaction events.
The motivation for this change is making sends to txFeed synchronous
instead of sending them in one-off goroutines launched by 'add' and
'promoteExecutables'. If a downstream consumer of txFeed is blocked for
a while, reorg requests and events will queue up.
* core: remove homestead check in TxPool
This change removes tracking of the homestead block number from TxPool.
The homestead field was used to enforce minimum gas of 53000 for
contract creations after the homestead fork, but not before it. Since
nobody would want configure a non-homestead chain nowadays and contract
creations usually take more than 53000 gas, the extra correctness is
redundant and can be removed.
* core: fixes for review comments
* core: remove BenchmarkPoolInsert
This is useless now because there is no separate code path for
individual transactions anymore.

* core: remove useless
* core: doesn't process head block in reorg function
* core: lookup txs by block number instead of block hash
Transaction hashes now store a reference to their corresponding
block number as opposed to their hash. In benchmarks this was
shown to reduce storage by over 12 GB.
The main limitation of this approach is that transactions on
non-canonical blocks could never be looked up, however that is
currently not supported.
The database version has been upgraded to version 5 and the
transaction lookup process is backwards-compatible with the
prior two transaction lookup formats prexisting in the
database instance. Tests have been added to ensure this.
* core/rawdb: tiny review nit fixes
This PR makes it easy to generate and execute testcases for VM arithmetic operations. By enabling and running the testcase TestWriteExpectedValues, a set of json files are created which contain input and output for each arith operation.
The test TestJsonTestcases executes all of those tests.
While meaningless as is, this PR makes it less risky to make changes (optimizations) to the vm operations, since there will be a larger body of testcases.
