Title: avoid sub-cent change (lost in fees) whenever possible Post by: Luke-Jr on March 01, 2011, 08:28:29 PM Pull request: https://github.com/bitcoin/bitcoin/pull/85
Starting a thread here, since it's not possible to comment on GitHub without agreeing to finance a legal battle when they get sued. Quote from: gavinandresen Looks good at first glance. Can we brainstorm test cases that we think might cause problems? In your first case, it should send 6 with a 0.0001 fee (this one is UNavoidable).E.g. Wallet with (only) available transactions of +1 +2.0001 +3 : Send 6 bitcoins; what happens? Same wallet, send 2 (I think you'll get a 2.0001+1 spend with 1.0001 change)... Any other tricky edge cases? |
