From d709815106824a3469b5f4152fd32705d7d142d4 Mon Sep 17 00:00:00 2001 From: obscuren Date: Thu, 8 May 2014 18:26:46 +0200 Subject: Added trans state and removed watch address etc The transient state can be used to test out changes before committing them to the proc state. The transient state is currently being used by the gui to support proper nonce updating without having to wait for a block. This used to be done by a cached state mechanism which can now safely by removed. --- ethchain/state_manager.go | 24 ++++++++---------------- ethchain/transaction_pool.go | 3 +-- 2 files changed, 9 insertions(+), 18 deletions(-) (limited to 'ethchain') diff --git a/ethchain/state_manager.go b/ethchain/state_manager.go index b8a893d15..fb5753ab3 100644 --- a/ethchain/state_manager.go +++ b/ethchain/state_manager.go @@ -50,6 +50,10 @@ type StateManager struct { // Comparative state it used for comparing and validating end // results compState *State + // Transiently state.
