From 0f616517e1f24a270b4599b04e16f21f7137d77e Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Thu, 8 Feb 2018 18:00:06 -0500 Subject: Fix ignoring tx data requests when fPauseSend is set on a peer This resolves a bug introduced in 66aa1d58a158991a8014a91335b5bc9c00062f56 where, if when responding to a series of transaction requests in a getdata we hit the send buffer limit and set fPauseSend, we will skip one transaction per call to ProcessGetData. Bug found by Cory Fields (@theuni).
