@terencechain 5fa43da fixes the build issue, and I updated some more of the signer api to build blob transactions. It builds, but still experimental. The surface area to create/sign new transactions is huge, there is a lot to update. |

There was a problem hiding this comment.
Naming nitpick: s/aggregateBlob/aggregateScalar
It's not actually a single blob that is aggregated in every aggregateBlob scalar; it's actually all the blobs.
We previously computed it in UnmarshalBinary() but in a wrong way (we considered the wrapped data as part of the inner length)

This commit squashes the op-geth fork history into a more maintainable diff for rebasing upon upstream geth. reference-optimistic-geth changes (origins of op-geth in early Bedrock development stage): - Deposit TX Type - Enable deposit tx in EVM/tx pool - Change deposit nonce to not be the max nonce - Extend PayloadAttributesV1 with a Transactions field - Force deposits at the start of each L2 block - Fix height check - noTxPool flag, reproduce block in verifier mode without tx pool interference - Fix RPC json marshalling (ref op-geth PR 4) - Deposit txs block height check in block body validation (ref op-geth PR 5) - core: do not try to reinject deposit txs into tx-pool (ref-op-geth PR 6) - deposit source hash field instead of L2 block height and tx index combination - Include invalid deposits, rewind state, but always persist mint (ethereum#10) - Provide gas to Call/Create in deposit transactions (ethereum#12) - Add docker builds (ref-op-geth PR 16, 17) - Don't panic on deposit transaction signature values or chain ID (ref-op-geth PR 18) - core: Add version to DepositTx (ref-op-geth PR 19) - Enable Geth build/lint/test in CircleCI (ref-op-geth PR 23) - core: Include guaranteed gas in the gas pool (ref-op-geth PR 21) - core: handle base fee, l1 availability fee, tx fee (ref-op-geth PR 27) - fix: deposit tx hash - fix l1 fee cache, rpc, tracing and tx pool - core: remove deposit-tx sub-type (a.k.a. deposit version byte) - eth/catalyst: allow engine user to reorg own chain - miner: restore ability to reorg deep as block builder - params: print Optimism consensus type in banner - core/types: remove unused protected() method, see upstream PR 23376 - core: do not mutate original balance value in tx pool l1 cost adjustment - core: subtract deposit gas from pool, so other txs do not use the same gas. And fail tx processing if deposits reach gas limit - core/types: deposits do not tip, avoid basefee subtraction - Unmeter the L1 Attributes Transaction - miner: handle force tx errors as critical, clean up diff - ci: Switch branch - eth,miner: return STATUS_INVALID when failing to process forced transactions in request (ref-op-geth PR 40) - verifier: forward tx to sequencer based on flag - txpool: add flag to disable tx gossip (ref-op-geth PR 42) - Add op-geth version in addition to geth version (ref-op-geth PR 43) - ci: CircleCI improvements (ref-op-geth PR 44) - Rename to op-geth - Build latest tag on optimism branch op-geth changes: - Expose cache config in simulated backend (#2) - Add EIP-1559 parameters - eth/catalyst: update payload id computation (#1) - make eip1559 configurable (#4) - post-merge network should not log warnings about missing transition information (#5) - Make the simulator more configurable (ethereum#6) - fix OPB-6 - IsDepositTx check instead of artificial nonce value check (ethereum#7) - Simulated backend - enable proof of stake consensus type and fix performance issue (ethereum#8) - accounts: simulated backend consensus engine option and immediate tx indexing - consensus/beacon: recognize all blocks as reached TTD with 0 TTD in chain config - Add --rollup.historicalhttp CLI flag and fix backend iface - Flags and interfaces for historical RPC requests (ethereum#12) - Redirect historical RPC requests (ethereum#13) - Use the pre-existing ethereum.NotFound error (ethereum#18) - Add historical endpoint to TraceBlockByNumber and TraceBlockByHash (ethereum#19) - Add historical endpoint to TraceTransaction (ethereum#20) - Add historical endpoint to TraceCall (ethereum#21) - optimism: fee params from info txi, update l1 cost func GPO params read (ethereum#15) - add hardcoded addresses for fee payouts (ethereum#23) - dynamic gas limit via engine API (ethereum#22) Co-authored-by: Matthew Slipper <me@matthewslipper.com> Co-authored-by: Joshua Gutow <jgutow@oplabs.co> Co-authored-by: protolambda <proto@protolambda.com> Co-authored-by: Mark Tyneway <mark.tyneway@gmail.com> Co-authored-by: Maurelian <maurelian@protonmail.ch>
