Introduce txpool.PendingFilter and migrate Pending(...) signatures from positional params to a typed struct.
- Add core/txpool.PendingFilter with MinTip/BaseFee fields for cheap call-site filtering
- Update txpool subpool interface and all call sites in eth/miner to pass the filter struct
- Keep behavior unchanged for empty filter (equivalent to previous nil,nil usage)
- Refresh legacypool tests to use the new API shape
This is a refactor-only change intended to improve API clarity and future extensibility without changing consensus or RPC semantics.
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).
Introduce dynamic-fee pre-filtering in txpool pending retrieval to reduce
allocations and downstream processing work during mining and tx propagation.
What changed:
- Change the `Pending` API from `Pending(enforceTips bool)` to
`Pending(minTip *uint256.Int, baseFee *uint256.Int)` in txpool interfaces.
- Implement pre-filtering in `legacypool.Pending` by comparing effective tip
against the provided `minTip/baseFee` for non-local, non-special txs.
- Update call sites to the new API:
- miner work assembly (`miner/worker.go`)
- tx sync (`eth/sync.go`)
- pool transaction retrieval (`eth/api_backend.go`)
- protocol/test interfaces (`eth/protocol.go`, `eth/helper_test.go`).
Tests:
- Add targeted coverage for pending filtering semantics in
`core/txpool/legacypool/legacypool_test.go`, including:
- minTip threshold boundary behavior
- baseFee-aware effective tip filtering
- local/special transaction exemption behavior
- dynamic-fee boundary behavior when baseFee is nil.
Impact:
- Preserves existing behavior while making pending selection cheaper for
downstream consumers.
- Improves confidence in edge-case behavior through dedicated tests.
* 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.
