This allows users to estimate gas on top of arbitrary blocks as well as pending and latest.
Tracing on pending is useful for most users as it takes into account the current txpool while
tracing on latest might be useful for users that have little to know knowledge of the current
transactions in the network.
If blockNrOrHash is not specified, estimateGas defaults to pending
This PR significantly changes the APIs for instantiating Ethereum nodes in
a Go program. The new APIs are not backwards-compatible, but we feel that
this is made up for by the much simpler way of registering services on
node.Node. You can find more information and rationale in the design
document: https://gist.github.com/renaynay/5bec2de19fde66f4d04c535fd24f0775.
There is also a new feature in Node's Go API: it is now possible to
register arbitrary handlers on the user-facing HTTP server. In geth, this
facility is used to enable GraphQL.
There is a single minor change relevant for geth users in this PR: The
GraphQL API is no longer available separately from the JSON-RPC HTTP
server. If you want GraphQL, you need to enable it using the
./geth --http --graphql flag combination.
The --graphql.port and --graphql.addr flags are no longer available.
This change introduces garbage collection for the light client. Historical
chain data is deleted periodically. If you want to disable the GC, use
the --light.nopruning flag.
This adds a test suite for discovery v4. The test suite is a port of the Hive suite for
discovery, and will replace the current suite on Hive soon-ish. The tests can be
run locally with this command:
devp2p discv4 test -remote enode//...

Exposing /debug/metrics and /debug/metrics/prometheus was dependent
on --pprof, which also exposes other HTTP APIs. This change makes it possible
to run the metrics server on an independent endpoint without enabling pprof.

For most use cases it can be beneficial to return the output even if there
was an error. This code should be changed anyway once the spec supports
error reasons in graphql responses

* all: seperate consensus error and evm internal error
There are actually two types of error will be returned when
a tranaction/message call is executed: (a) consensus error
(b) evm internal error. The former should be converted to
a consensus issue, e.g. The sender doesn't enough asset to
purchase the gas it specifies. The latter is allowed since
evm itself is a blackbox and internal error is allowed to happen.
This PR emphasizes the difference by introducing a executionResult
structure. The evm error is embedded inside. So if any error
returned, it indicates consensus issue happens.
And also this PR improve the `EstimateGas` API to return the concrete
revert reason if the transaction always fails

This PR adds service value measurement statistics to the light client. It
also adds a private API that makes these statistics accessible. A follow-up
PR will add the new server pool which uses these statistics to select
servers with good performance.
This document describes the function of the new components:

ToMessage is used to convert between ethapi.CallArgs and types.Message.
It reduces the length of the DoCall method by about half by abstracting out
the conversion between the CallArgs and the Message. This should improve the
code's maintainability and reusability.
Prior to this change, eth_call changed the balance of the sender account in the
EVM environment to 2^256 wei to cover the gas cost of the call execution.
We've had this behavior for a long time even though it's super confusing.
This commit sets the default call gasprice to zero instead of updating the balance,
which is better because it makes eth_call semantics less surprising. Removing
the built-in balance assignment also makes balance overrides work as expected.
This makes eth_call and eth_estimateGas use the zero address
as sender when the "from" parameter is not supplied.

This replaces the JavaScript interpreter used by the console with goja,
which is actively maintained and a lot faster than otto. Clef still uses otto
and eth/tracers still uses duktape, so we are currently dependent on three
different JS interpreters. We're looking to replace the remaining uses of otto
soon though.
* log: delete RotatingFileHandler
We added this for the dashboard, which is gone now. The
handler never really worked well and had data race and file
handling issues.
* internal/debug: remove unused RotatingFileHandler setup code
* build: remove env.sh
This removes the dirty symlink-to-self hack we've had for years. The
script was added to enable building without GOPATH and did that job
reliably for all this time. We can remove the workaround because modern
Go supports building without GOPATH natively.
* Makefile: add GO111MODULE=on to environment
* internal/testlog: print file+line number of log call in test log
This changes the unit test logger to print the actual file and line
number of the logging call instead of "testlog.go:44".
Output of 'go test -v -run TestServerListen ./p2p' before this change:

Most of these changes are related to the Go 1.13 changes to test binary

* cmd/geth: make attach tests more reliable
This makes the test wait for the endpoint to come up by polling
it instead of waiting for two seconds.
* tests: fix test binary flags for Go 1.13
Calling flag.Parse during package initialization is prohibited
as of Go 1.13 and causes test failures. Call it in TestMain instead.

Calling flag.Parse during package initialization is prohibited
as of Go 1.13 and causes test failures. Call it in TestMain instead.
* build: remove workaround for ./... vendor matching
This workaround was necessary for Go 1.8. The Go 1.9 release changed
the expansion rules to exclude vendored packages.
* Makefile: use relative path for GOBIN
This makes the "Run ./build/bin/..." line look nicer.
* les: fix test binary flags for Go 1.13
Calling flag.Parse during package initialization is prohibited
as of Go 1.13 and causes test failures. Call it in TestMain instead.
* graphql, internal/ethapi: extend eth_call
This PR offers the third option parameter for eth_call API.
Caller can specify a batch of contracts for overriding the
original account metadata(nonce, balance, code, state).
It has a few advantages:
* It's friendly for debugging
* It's can make on-chain contract lighter for getting rid of
state access functions
* core, internal: address comments
* accounts/mananger, internal/ethapi/api: Add new function AllAccounts on account manager to remove the duplication code on getting all wallets accounts
* Rename to Accounts
* Rename to AllAccounts
This change ensures 'blockHash', 'blockNumber' and 'transactionIndex'
are set to null for pending transactions. This behavior is required by
the Ethereum JSON-RPC spec.

Until this commit, when sending an RPC request that called `NewEVM`, a blank `vm.Config`
would be taken so as to set some options, based on the default configuration. If some extra
configuration switches were passed to the blockchain, those would be ignored.
This PR adds a function to get the config from the blockchain, and this is what is now used
for RPC calls.
Some subsequent changes need to be made, see https://github.com/ethereum/go-ethereum/pull/17955#pullrequestreview-182237244
for the details of the discussion.
