From b604c5c8b5892842f13dee89ae31812a28ab25d1 Mon Sep 17 00:00:00 2001 From: Russell Yanofsky Date: Fri, 15 May 2020 09:23:55 -0400 Subject: wallet: Minimal fix to restore conflicted transaction notifications This fix is a based on the fix by Antoine Riard in https://github.com/bitcoin/bitcoin/pull/18600. Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd77eed497a8e251d31358e16e2f2eb1 and 7e89994133725125dddbfa8d45484e3b9ed51c6e from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325. The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations.
