refactor touched accounts, selfdestruct, and log
simplify EVM and delegete those things to accounts cache.
also no more manual state clearing, accounts cache will be
responsible for both collecting touched account and perform
state clearing.

More on withdrawals (#1508)
* Gwei conversion should use u256 because u64 can overflow.

* Make withdrawals follow the EIP-158 state-clearing rules.

(i.e. Empty accounts should be deleted.)

* Allow the zero address in normalizeNumber.

(Necessary for one of the new withdrawals-related tests.)

* Another fix with a withdrawals-related test.

Redesign of BaseVMState descriptor (#923)
* Redesign of BaseVMState descriptor

why:
  BaseVMState provides an environment for executing transactions. The
  current descriptor also provides data that cannot generally be known
  within the execution environment, e.g. the total gasUsed which is
  available not before after all transactions have finished.

  Also, the BaseVMState constructor has been replaced by a constructor
  that does not need pre-initialised input of the account database.

also:
  Previous constructor and some fields are provided with a deprecated
  annotation (producing a lot of noise.)

* Replace legacy directives in production sources

* Replace legacy directives in unit test sources

* fix CI (missing premix update)

* Remove legacy directives

* chase CI problem

* rebased

* Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation

why:
  Constructing a new 'AccountsCache' descriptor can be avoided sometimes
  when the current state root is properly positioned already. Such a
  feature existed already as the update function 'initStateDB()' for the
  'BaseChanDB' where the accounts cache was linked into this desctiptor.

  The function 'initStateDB()' was removed and re-implemented into the
  'BaseVmState' constructor without optimisation. The old version was of
  restricted use as a wrong accounts cache state would unconditionally
  throw an exception rather than conceptually ask for a remedy.

  The optimised 'BaseVmState' re-initialisation has been implemented for
  the 'persistBlocks()' function.

also:
  moved some test helpers to 'test/replay' folder

* Remove unused & undocumented fields from Chain descriptor

why:
  Reduces attack surface in general & improves reading the code.

EIP-1559: Fee market change for ETH 1.0 chain
Transaction and BlockHeader already updated in nim-eth repo
to support EIP-1559

EIP-1559 header validation and gasLimit validation
already implemented in previous commit

This commit deals with block validation:
- Effective gasPrice per EIP-1559
- new miner reward based on priorityFee

Jordan Hrycaj 69a1ee5fc8 re-named some v2state_transactions.nim to its original name without the v2
also:
  re-integrated stack_defs.nim back into stack.nim

why:
  the v2 prefix of the file name was used as a visual aid when
  comparing vm2 against vm sources
2021-04-28 15:24:14 +03:00
Jordan Hrycaj ff6921eb1a re-named some v2*.nim sources to its original name *.nim (without the v2)
why:
  the v2 prefix of the file name was used as a visual aid when
  comparing vm2 against vm sources

details:
  all renamed v2*.nim sources compile locally with the -d:kludge:1 flag
  set or without (some work with either)

  only sources not renamed yet: v2state_transactions.nim
2021-04-28 15:24:14 +03:00
Jordan Hrycaj 18587f5496 move setupTxContext() from v2state.nim to v2state_transactions.nim
why:
  removes circular dependency in v2state.nim which is more used than
  v2state_transactions.nim
2021-04-28 15:24:14 +03:00
Jordan Hrycaj f159e67bba renamed states*.nim => v2states*.nim
why:
  these files provide part of the externally accessible interface
  provided by vm_state*.nim. so the new filename indicates that the
  source code belongs to vm2 (rather than vm).
2021-04-23 14:04:06 +03:00
Jordan Hrycaj b4f8450968 provide identical copy of vm folder => vm2, activated by make flag ENABLE_VM2=1
why:
  vm2 enabled by ENABLE_VM2=1 behaves as vm without ENABLE_EVMC=1 until
  it doesn't in some future fatch set. this leaves some wiggle room
  to work on a vm copy without degrading the original implementation.

details:
  + additional make flag ENABLE_VM2=1 (or ENABLE_VM2=0 to explicitely disable)
  + when both flags ENABLE_EVMC=1 and ENABLE_VM2=1 are present, the former
    flag ENABLE_EVMC=1 takes precedence, this is implemented at the NIM
    compiler level for -d:evmc_enabled and -d:vm2_enabled

Jordan Hrycaj 9e365734e6
renamed nvm_ prefixed modules to its original names
why:
  the nvm_ prefix was used inside the vm folder to hide them temporarily
  from the outside world while writing export wrappers. now all
  functionality is accessed via vm_*, rather than vm/* imports.

todo:
  at a later stage the import headers of the vm modules need to get fixed
  to meet style guide standards (as jacek kindly pointed out.)
