From c376ac359ec8551823b4ee14c85d85a49f2d3436 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Sun, 15 Apr 2012 16:52:09 -0400 Subject: [PATCH] Fix loop index var types, fixing many minor sign comparison warnings foo.size() typically returns an unsigned integral type; make loop variables match those types' signedness. --- src/addrman.cpp | 4 ++-- src/bitcoinrpc.cpp | 2 +- src/main.cpp | 38 +++++++++++++++++++------------------- src/main.h | 12 ++++++------ src/net.cpp | 6 +++--- src/netbase.cpp | 2 +- src/protocol.cpp | 2 +- src/uint256.h | 2 +- src/wallet.cpp | 14 +++++++------- src/wallet.h | 6 +++--- 10 files changed, 44 insertions(+), 44 deletions(-) diff --git a/src/addrman.cpp b/src/addrman.cpp index 8fb40b46..11dd2a7b 100644 --- a/src/addrman.cpp +++ b/src/addrman.cpp @@ -124,7 +124,7 @@ int CAddrMan::SelectTried(int nKBucket) // random shuffle the first few elements (using the entire list) // find the least recently tried among them int64 nOldest = -1;
