utACK 1e747e3. @instagibbs Yes, I read that as "if we're into witness validation, SCRIPT_VERIFY_CLEANSTACK is assumed" |
|
it's more "if we're into witness validation, cleanstack is implied (regardless of SCRIPT_VERIFY_CLEANSTACK)" |

…a SCRIPT_ERR_CLEANSTACK error code 1e747e3 Make segwit failure due to CLEANSTACK violation return a SCRIPT_ERR_CLEANSTACK error code. (Mark Friedenbach) Pull request description: If a segwit script terminates with a stack size not equal to one, the current error code is EVAL_FALSE. This is semantically wrong, and prevents explicitly checking CLEANSTACK violations in the unit tests. This PR changes the error code (and affected unit tests) to use SCRIPT_ERROR_CLEANSTACK instead of SCRIPT_ERROR_EVAL_FALSE.
