Geth OVM Integration (ExecutionManager/StateManager) (ethereum#9)
* Get basic getStorage/setStorage stubs working * Clean up tests * Add state_manager * Add StateManager set & getStorage * Add state mananger create function * Add get & increment nonce * Add getCodeContractBytecode * Add GetCodeContractHash * Add getCodeContractHash to the state manager * Add associateCodeContract to state manager * Pass the tests * go fmt * Add stateTransition to test with * Fix tests * Test deploying contract with transition state * Call executeTransaction on contract deployment * Added ExecutionManager deployment * Get contract deployments working * Cleanup logging * Get stubbed ExecutionManager working * Get a simple contract to deploy through the ExecutionManager * Refactor simpleAbiEncode * Revert unnecessary changes * Remove comments * Revert changes outside of this PR * Revert changes outside of this PR * Revert changes outside of this PR * Fix broken tests * Move OVM bytecode & ABI into constants * Add crazy printlines * Remove crazy comments * Add a bunch of debug printlns * Add helper fn for applying msgs to the EVM * Update ExecutionManager bytecode * Shim CREATE for EM to use correct addr * Add SimpleStorage test * Add the EM/SM to all new states * Force all txs to be routed through the EM * Remove unused files * Remove unused comments * Increment nonce after failed tx * Add debug statements * Use evm.Time for timestamp * Change EM deployment, fix broken tests, clean up * Add an OVM test & remove printlns * Fix lint errors & remove final printlns * Final cleanup--remove some comments * Limiting Geth to one transaction per block (#3) * Limiting Geth to one transaction per block * Adding TransitionBatchBuilder to build & submit rollup blocks * Adding L1MessageSender to Transaction (#4) * Adding L1MessageSender to Transaction * Adding logic to omit L1MessageSender in encoding / decoding when nil and never use it in hash computation Co-authored-by: ben-chain <[email protected]> * Fixing Geth Tests (ethereum#6) Fixing broken tests, skipping tests we intentionally break, and configuring CI within Github Actions * Hex Trie -> Binary Trie (ethereum#7) *** Changing Hex Trie to Binary Trie *** Note: This changes and/or comments out a bunch of tests, so if things break down the line, this is likely the cause! * Ingest Block Batches (ethereum#8) Handling BlockBatches in Geth at `SendBlockBatches` endpoint (eth_sendBlockBatches) Other: * Adding PR template * Adding ability to set timestamp and making blocks use configured timestamp * Adding ability to encode original tx nonce in calldata * Adding L1MessageSender to Contract Creation Txs * Add L1MessageSender to Message * Increment nonce on CREATE failure * Fix bug where evm.Time=0 * Use state dump with hardcoded EM & SM addrs - ExecutionMgr address should always be 0x0000...dead0000 - StateMgr address should always be 0x0000...dead0001 * Move EM deployment into genesis block maker * Update EM contracts to latest version * Update EM to remove events * Fix the OVM tests * Skip an ungodly number of tests * Fix lint errors * Clean up logging * Cleanup more logs * Use local reference to state manager * Rename applyOvmToState(..) * Remove unneeded check * Clean up logging & add EM ABI panic * Add gas metering to SM & small refactor * Update core/vm/state_manager.go Co-authored-by: Kevin Ho <[email protected]> Co-authored-by: Mason Fischer <[email protected]> Co-authored-by: Will Meister <[email protected]> Co-authored-by: ben-chain <[email protected]> Co-authored-by: Kevin Ho <[email protected]>
