Matthieu Vachon	a09a610384	core/tracing: add system call callback when performing `ProcessBeaconBlockRoot` (#29355) ... Added a start/end system where tracer can be notified that processing of some Ethereum system calls is starting processing and also notifies it when the processing has completed. Doing a start/end for system call will enable tracers to "route" incoming next tracing events to go to a separate bucket than other EVM calls. Those not interested by this fact can simply avoid registering the hooks. The EVM call is going to be traced normally afterward between the signals provided by those 2 new hooks but outside of a transaction context OnTxStart/End. That something implementors of live tracers will need to be aware of (since only "trx tracers" are not concerned by ProcessBeaconRoot). --------- Co-authored-by: Sina Mahmoodi <itz.s1na@gmail.com>	9 months ago

Sina M	064f37d6f6	eth/tracers: live chain tracing with hooks (#29189) ... 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: Matthieu Vachon <matthieu.o.vachon@gmail.com> Co-authored-by: Delweng <delweng@gmail.com> Co-authored-by: Martin HS <martin@swende.se>	11 months ago
