Here we add a Go API for running tracing plugins within the main block import process. As an advanced user of geth, you can now create a Go file in eth/tracers/live/, and within that file register your custom tracer implementation. Then recompile geth and select your tracer on the command line. Hooks defined in the tracer will run whenever a block is processed. The hook system is defined in package core/tracing. It uses a struct with callbacks, instead of requiring an interface, for several reasons: - We plan to keep this API stable long-term. The core/tracing hook API does not depend on on deep geth internals. - There are a lot of hooks, and tracers will only need some of them. Using a struct allows you to implement only the hooks you want to actually use. All existing tracers in eth/tracers/native have been rewritten to use the new hook system. This change breaks compatibility with the vm.EVMLogger interface that we used to have. If you are a user of vm.EVMLogger, please migrate to core/tracing, and sorry for breaking your stuff. But we just couldn't have both the old and new tracing APIs coexist in the EVM. --------- Co-authored-by: Sina M <1591639+s1na@users.noreply.github.com> Co-authored-by: Matthieu Vachon <matthieu.o.vachon@gmail.com> Co-authored-by: Delweng <delweng@gmail.com> Co-authored-by: Martin HS <martin@swende.se>
