From 9c7722b7c5ce49130bd978b932f73b629ce5cebe Mon Sep 17 00:00:00 2001 From: Luke Dashjr Date: Sun, 27 May 2012 23:06:09 +0000 Subject: [PATCH] Store a fixed order of transactions (and accounting) in the wallet For backward compatibility, new accounting data is stored after a \0 in the comment string. This way, old versions and third-party software should load and store them, but all actual use (listtransactions, for example) ignores it. --- src/rpcwallet.cpp | 12 ++-- src/test/accounting_tests.cpp | 123 ++++++++++++++++++++++++++++++++++ src/wallet.cpp | 3 + src/wallet.h | 83 ++++++++++++++++++++++- src/walletdb.cpp | 97 ++++++++++++++++++++++++++- src/walletdb.h | 4 ++ 6 files changed, 315 insertions(+), 7 deletions(-) create mode 100644 src/test/accounting_tests.cpp diff --git a/src/rpcwallet.cpp b/src/rpcwallet.cpp index 3b68105d..005a7766 100644 --- a/src/rpcwallet.cpp +++ b/src/rpcwallet.cpp @@ -542,6 +542,7 @@ Value movecmd(const Array& params, bool fHelp) // Debit CAccountingEntry debit;
