Martin Holst Swende 7770e41cb5 core: improve contextual information on core errors (#21869) ... A lot of times when we hit 'core' errors, example: invalid tx, the information provided is insufficient. We miss several pieces of information: what account has nonce too high, and what transaction in that block was offending? This PR adds that information, using the new type of wrapped errors. It also adds a testcase which (partly) verifies the output from the errors. The first commit changes all usage of direct equality-checks on core errors, into using errors.Is. The second commit adds contextual information. This wraps most of the core errors with more information, and also wraps it one more time in stateprocessor, to further provide tx index and tx hash, if such a tx is encoutered in a block. The third commit uses the chainmaker to try to generate chains with such errors in them, thus triggering the errors and checking that the generated string meets expectations.		4 years ago
