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.

The name of a method’s receiver should be a reflection of its identity;
often a one or two letter abbreviation of its type suffices (such as
“c” or “cl” for “Client”). Don’t use generic names such as “me”, “this”
or “self”, identifiers typical of object-oriented languages that place
more emphasis on methods as opposed to functions. The name need not be
as descriptive as that of a method argument, as its role is obvious and
serves no documentary purpose. It can be very short as it will appear
on almost every line of every method of the type; familiarity admits
brevity. Be consistent, too: if you call the receiver “c” in one method,
don’t call it “cl” in another.
* eth: chain config (genesis + fork) ENR entry
* core/forkid, eth: protocol independent fork ID, update to CRC32 spec
* core/forkid, eth: make forkid a struct, next uint64, enr struct, RLP
* core/forkid: change forkhash rlp encoding from int to [4]byte
* eth: fixup eth entry a bit and update it every block
* eth: fix lint
* eth: fix crash in ethclient tests
* V2 truncate MaxMasternodes from candidates after penalty,
V1 same as before
TestUpdateMultipleMasterNodes: test V2, in snapshot we have all candidates, but at epoch switch, we pick MaxMasternodes
* code looks better
* add isEpochSwitch function and refactor utils
* fix broken first v2 epoch switch block
* use adaptor epoch switch function to determine v1 v2 epoch swtich block
* add test for the GetMasternodesByNumber and GetCurrentEpochSwitchBlock function
* add v2 test for isAuthroisedAddress
* Use GetCurrentEpochSwitchBlock in findNearestSignedBlock api
