Jeff Garzik fa7e80b8 2011-02-17T01:21:16 Extract get-work logic into separate function.
Jeff Garzik 6d288293 2011-02-13T03:04:02 Add support for JSON-format configuration file
Jeff Garzik c0935a94 2011-02-10T00:41:44 Re-use CURL object, thereby caching DNS and HTTP connections where possible.
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.
