Switch LazyTransaction gas caps from *big.Int to *uint256.Int and convert once at pending retrieval time.
In miner ordering, keep fee comparisons on uint256 and precompute TRC21 gas price in uint256 form to avoid repeated big-int conversions in heap comparisons.
Also update affected tests and call sites in legacypool/worker/helper paths.
Compatibility: LazyTransaction exported field types changed (GasFeeCap/GasTipCap).
* refactor(txpool): remove wrapper type #27841
Partial backport of ethereum/go-ethereum PR #27841, limited to txpool wrapper removal.
- Migrate txpool interfaces/call sites from `*txpool.Transaction` to `*types.Transaction`
- Update eth/miner/contracts paths and related tests accordingly
- No intended behavior change
Blob sidecar validation/handling changes from upstream are not included here.
* refactor(core/txpool): migrate tx subscription to SubscribeTransactions #28243
Replace the old SubscribeNewTxsEvent-style plumbing with the new
SubscribeTransactions(ch, reorgs) interface across txpool, eth protocol
manager, API backend, miner worker, and test helpers.
Key changes:
- Extend txpool/subpool tx subscription interface with a reorgs flag
- Route eth tx announcement path to reorgs=false (new tx announcements only)
- Route API/miner subscriptions to reorgs=true
- Move subscription-scope cleanup to TxPool.Close()
- Add Gas field to LazyTransaction in legacy pending view
Note:
LegacyPool currently cannot strictly separate newly seen and resurrected txs,
so the reorgs flag is accepted for API compatibility and future blob-subpool
integration.
