* params, core/vm: deprecating gastable, part 1
* core/vm, params: deprecate gastable, use both constant and dynamic gas
* core/vm, params: remove gastable, remove copypaste
* core/vm: make use of the chainrules
* interpreter: make tracing count constant+dynamic gas
* core/vm: review concerns (param/method name changes)
* core/vm: make use of chainrules more
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.
* core/vm: remove function call for stack validation from evm runloop
* core/vm: separate gas calc into static + dynamic
* core/vm: optimize push1
* core/vm: reuse pooled bigints for ADDRESS, ORIGIN and CALLER
* core/vm: use generic error message for jump/jumpi, to avoid string interpolation
* testdata: fix tests for new error message
* core/vm: use 64-bit memory calculations
* core/vm: fix error in memory calculation
* core/vm: address review concerns
* core/vm: avoid unnecessary use of big.Int:BitLen()
This PR adds a new fork which disables EIP-1283. Internally it's called Petersburg,
but the genesis/config field is ConstantinopleFix.
The block numbers are:
7280000 for Constantinople on Mainnet
7280000 for ConstantinopleFix on Mainnet
4939394 for ConstantinopleFix on Ropsten
9999999 for ConstantinopleFix on Rinkeby (real number decided later)
This PR also defaults to using the same ConstantinopleFix number as whatever
Constantinople is set to. That is, it will default to mainnet behaviour if ConstantinopleFix
is not set.This means that for private networks which have already transitioned
to Constantinople, this PR will break the network unless ConstantinopleFix is
explicitly set!
This adds the global accumulated refund counter to the standard
json output as a numeric json value. Previously this was not very
interesting since it was not used much, but with the new sstore
gas changes the value is a lot more interesting from a consensus
investigation perspective.
* first impl of eth_getProof
* fixed docu
* added comments and refactored based on comments from holiman
* created structs
* handle errors correctly
* change Value to *hexutil.Big in order to have the same output as parity
* use ProofList as return type
Interpreter initialization is left to the PRs implementing them.
Options for external interpreters are passed after a colon in the
`--vm.ewasm` and `--vm.evm` switches.
Makes Interface interface a bit more stateless and abstract.
Obviously this change is dictated by EVMC design. The EVMC tries to keep the responsibility for EVM features totally inside the VMs, if feasible. This makes VM "stateless" because VM does not need to pass any information between executions, all information is included in parameters of the execute function.
This commit does a few things at once:
- Updates the tests to contain the latest data from ethereum/tests repo.
- Enables Constantinople state tests. This is needed to be able to
fuzz-test the evm with constantinople rules.
- Fixes the error in opSAR that we've known about for some time. I was
kind of saving it to see if we hit upon it with the random test
generator, but it's difficult to both enable the tests and have the
bug there -- we don't want to forget about it, so maybe it's better
to just fix it.
- Update benchmarks to use a pool of int pools.
Unless benchmarks are aborted with segmentation fault.

- Define an Interpreter interface
- One contract can call contracts from other interpreter types.
- Pass the interpreter to the operands instead of the evm.
This is meant to prevent type assertions in operands.
* vm/test: add tests+benchmarks for mstore
* core/vm: less alloc and copying for mstore
* core/vm: less allocs in sload
* vm: check for errors more correctly
