Jeff Garzik e47076ca 2011-02-04T11:54:31 Fix max-nonce auto-adjustment logic to actually work
Jeff Garzik e8ee4cb0 2011-02-03T00:54:03 Add --retry-pause, to set length of pause time between failure retries
Jeff Garzik 714c0fd7 2011-02-03T00:46:55 Continue scanhash, even if high 32 bits are zero. Previously, we would stop the scan if the high 32 bits of the hash were zero, as a quick shortcut for testing the full hash. If this quick test succeeded, we would pass the work to the server for full validation. Change this logic to perform full validation inside minerd, so that work may be resumed more quickly if hash > target.
