details:
For documentation, see comments in the file tx_pool.nim.
For prettified manual pages run 'make docs' in the nimbus directory and
point your web browser to the newly created 'docs' directory.
why:
Previous version was based on lru_cache which is ugly. This module is
based on the stew/keyed_queue library module.
other:
There are still some other modules rely on lru_cache which should be
removed.
* crash test scenario
details:
Example code for inspecting nested block chain and accounts cache
database transaction framework. There seems to be a pathological
case where the system crashes after a rollback (as appeared in the
tx-pool packer code.)
* simplified crash scenario
* Workable solution (as suggested by Andri)
details:
Avoiding db.rollback() (db.commit() is OK) while vmState.stateDB is
alive.
* Rename text_txcrash => test_accounts_cache
why:
Unit tests covers part of accounts_cache handling
* comment update
* PoW wrapper for verification & mining
why:
It eases data management of per-Epoch lookup tables. Also some unit
tests show limits of usefulness on non-specialised machines for
mining besides developing tests.
details:
For PoW verification, this patch provides a pretty wrapper hiding the
details of the ethash/Hashimoto lookup cache management.
For mining on my development system without special hardware, the
underlying ethash functions are prohibitively slow. It takes
* ~20 minutes to prepare the full ethash/Hashimoto lookup dataset
* a second to run ~25k nonce tests (in the mining loop)
The mining part might be of some use for generating test data for
the tx-pool, though.
* Using PowRef as replacement for EpochHashCache + hashimotoLight()
* Fix typo (CI failed)
why:
was below log level when testing locally
* fix canonical naming
why:
source-local unit tests would hardly be triggered by github CI as rightly
criticised with the last patch.
details:
source-local unit tests have been moved to tests folder.
this version also contains rlp serialisation code so rlp encode/decode
will apply tranparently. this is not needed in p2p/validate but will be
useful with the clique protocol.
- port to new APIs
- added copyright headers
- bumped the copyright interval in modified files
- fixed tests
- reorganised imports
- normalised function names
- deleted some trailing space
- added test_rpc to all_tests
- assert() -> doAssert()
- moved the RPC port in a constant for the test suite
* move forks constants, rename errors

* Update with 30s, 40s, 50s opcodes + impl of balance + stack improvement
* add push, dup, swap, log, create and call operations
* finish opcode implementation
* Add the new dispatching logic
* Pass the opcode test
* Make test_vm_json compile
* halt execution without exceptions for Return, Revert, selfdestruct (fix#62)
* Properly catch and recover from EVM exceptions (stack underflow ...)
* Fix byte op
* Fix jump regressions
* Update for latest devel, don't import old dispatch code as quasiBoolean macro is broken by latest devel
* Fix sha3 regression on empty memory slice and until end of range slice
* Fix padding / range error on expXY_success (gas computation left)
* update logging procs
* Add tracing - expXY_success is not a regression, sload stub was accidentally passing the test
* Reuse the same stub as OO implementation
* Delete previous opcode implementation
* Delete object oriented fork code
* Delete exceptions that were used as control flows
* delete base.nim 🔥, yet another OO remnants
* Delete opcode table
* Enable omputed gotos and compile-time gas fees
* Revert const gasCosts -> generates SIGSEGV
* inline push, swap and dup opcodes
* loggers are now template again, why does this pass new tests?
* Trigger CI rebuild after rocksdb fix https://github.com/status-im/nim-rocksdb/pull/5
* Address review comment on "push" + VMTests in debug mode (not release)
* Address review comment: don't tag fork by default, make opcode impl grepable
* Static compilation fixes after rebasing
* fix the initialization of the VM database
* add a missing import
* Deactivate balance and sload test following #59
* Reactivate stack check (deactivated in #59, necessary to pass tests)
* Merge remaining opcodes implementation from #59
* Merge callDataLoad and codeCopy fixes, todo simplify see #67
Merge note: currently cannot compile due to `quasiBoolean` (#63). This will be solved by https://github.com/status-im/nimbus/pull/65
----
* Implemented most of the stubbed out state handling instructions
The code compiles, but still fails at the moment due to incorrect
initialization of the VM. Don't merge yet. More commits will be
pushed in the coming days.
* Fixed crash
* trie put and del are void now
* getBlockTransactionData and getReceipts
* Working code for extcodesize0.json
* fix origin.json
* fix calldatasize1
* fix calldataloadSizeTooHighPartial
* fix calldataloadSizeTooHigh
* more efficient PushX implementation
* fix and, or, xor
* Move and cleanup interpreter files - prepare for redesign of VM
* fix call comment aobut recursive dependencies
* memory: use a template again and avoid (?) a cstring-> string conversion
* Fix stack test regression
* Fix recursive dependency on logging_ops, test_vm_json compiles but regression :/
* Fix signextend regression
* Fix 3 signed test and sha3 test
* Decoupling op logic and gas - introduce gasometer, rework opcode declaration
* Remove gas constants for gas opcode computation
* Remove gas constants for precompiled contracts
* make vm_types compile
* Make opcode, call and computation compile
* Distinguish between dynamic and complex gas costs, fix arithmetic
* Fix context and sha3
* update memory and storage ops
* Log opcode uses memory expansion code
* update/stub system_ops with gas costs
* Make test compile. Deactivate stub test_vm
* all tests compiles, opcode fails due to https://github.com/nim-lang/Nim/issues/8007 (const object variant in tables reset at runtime)
* Create an enum without holes - workaround: https://github.com/nim-lang/Nim/issues/8007
* Use arrays instead of tables for GasCosts, remove some unused imports - passing all basic tests!
* Make test_vm_json compile
* Fix test_vm_json - workaround https://github.com/nim-lang/Nim/issues/8015
* fix memory expansion cost bug
* Remove leftover special handling from before GckMemExpansion
* cleanup outdated comment, better align =
* Fix sha3 gas cost not taking memory expansion into account
* Improve gas error reporting of test_vm_json
* Fix gas computation regression due to mem expansion
* mass replace for memExpansion->RequestedMemSize was too eager
* fix log gas cost (no tests :/)
* missed a static FeeSchedule

* Enable vm_tests, remove usage of from keyword as a variable name
* Fix Genesis types and use the new EthTime
* Add a new VMKind enum (py-evm vmclass runtime type)

* For now blockNumbers are UInt256
* EoD merge: vm_test compiles and does not throw computation error
* running full transactions is too early
