From: Pieter Wuille Date: Wed, 1 Jun 2011 16:27:05 +0000 (+0200) Subject: move wallet code to separate file X-Git-Tag: v0.4.0-unstable~234^2~30^2~1 X-Git-Url: https://git.novaco.in/?p=novacoin.git;a=commitdiff_plain;h=e89b9f6a2abaa120ff0fc3cea9ae364e8cbd25e4 move wallet code to separate file This introduces two new source files, keystore.cpp and wallet.cpp with corresponding headers. Code is moved from main and db, in a preparation for a follow-up commit which introduces the classes CWallet and CKeyStore. --- diff --git a/src/db.cpp b/src/db.cpp index b67e2a6..30e4bb0 100644 --- a/src/db.cpp +++ b/src/db.cpp @@ -584,9 +584,6 @@ bool LoadAddresses() // CWalletDB // -static set setKeyPool;
