From 14a1e96b68386d28b26e82f4dae2a86062d3b355 Mon Sep 17 00:00:00 2001 From: jp-imx <109574657+jp-imx@users.noreply.github.com> Date: Mon, 20 Nov 2023 19:05:20 +1100 Subject: [PATCH] core/txpool/legacypool: respect nolocals-setting (#28435) This change adds a check to ensure that transactions added to the legacy pool are not treated as 'locals' if the global locals-management has been disabled. This change makes the pool enforce the --txpool.pricelimit setting. --- core/txpool/legacypool/legacypool.go | 3 ++ core/txpool/legacypool/legacypool_test.go | 44 +++++++++++++++++++++++ 2 files changed, 47 insertions(+) diff --git a/core/txpool/legacypool/legacypool.go b/core/txpool/legacypool/legacypool.go index 0e33923274..8450d89a2c 100644 --- a/core/txpool/legacypool/legacypool.go +++ b/core/txpool/legacypool/legacypool.go @@ -959,6 +959,9 @@ func (pool *LegacyPool) addRemoteSync(tx *types.Transaction) error { // If sync is set, the method will block until all internal maintenance related // to the add is finished.
