Debugging recent geth failures in hive, it took a while to realize that it's because
geth doesn't support eth/65 any longer. This PR makes such failures a bit more
easy to figure out.
This PR offers two more database sub commands for exporting and importing data.
Two exporters are implemented: preimage and snapshot data respectively.
The import command is generic, it can take any data export and import into leveldb.
The data format has a 'magic' for disambiguation, and a version field for future compatibility.

This PR adds functionality to the evm t8n to calculate ethash difficulty. If the caller does not provide a currentDifficulty, but instead provides the parentTimestamp (well, semi-optional, will default to 0 if not given), and parentDifficulty, we can calculate it for him.
The caller can also provide a parentUncleHash. In most, but not all cases, the parent uncle hash also affects the formula. If no such hash is provided (or, if the empty all-zero hash is provided), it's assumed that there were no uncles.
This PR adds flag to enable InfluxDB v2 (--metrics.influxdbv2), flags for v2-specific features (--metrics.influxdb.token, --metrics.influxdb.bucket), also carries over addition of support for specifying organization (--metrics.influxdb.organization), but still retains backwards compatibility with InfluxDB v1.
In many cases, it's desireable to use already-signed transactions as input to the state transition, instead of having the evm sign them internally (for example to use malformed or not-yet-valid transactions). This PR adds support + docs for that feature.
This PR modifies the post-PING-send expectations to both be laxer and stricter: it doesn't care what order the packets arrive, but also verifies that exactly one PING and one PONG is returned.
When processing a transaction with London fork rules, EIP-1559 mandates
checking that the sender must have sufficient balance to cover gas * gasFeeCap.
In the EIP's pseudocode, this check happens after the value transferred by the
transaction has already been deducted. However, in go-ethereum, the balance
has not yet been updated when the check happens, and therefore needs to be
added explicitly.

Previously, the test waited a second and then failed if geth had not
started. This caused the test to fail intermittently. This change checks
whether the IPC is open 10 times over a 5 second period and then fails
if geth is still not available.
This PR refactors the eth test suite to make it more readable and
easier to use. Some notable differences:
- A new file helpers.go stores all of the methods used between
both eth66 and eth65 and below tests, as well as methods shared
among many test functions.
- suite.go now contains all of the test functions for both eth65
tests and eth66 tests.
- The utesting.T object doesn't get passed through to other helper methods,
but is instead only used within the scope of the test function,
whereas helper methods return errors, so only the test function
itself can fatal out in the case of an error.
- The full test suite now only takes 13.5 seconds to run.
This is the initial implementation of EIP-1559 in packages core/types and core.
Mining, RPC, etc. will be added in subsequent commits.

This changes the SimultaneousRequests test to send the requests from the same
connection, as it doesn't really make sense to test whether a node can respond
to two requests with different request IDs from separate connections.
This removes auto-configuration of the snap.*.ethdisco.net DNS discovery tree.
Since measurements have shown that > 75% of nodes in all.*.ethdisco.net support
snap, we have decided to retire the dedicated index for snap and just use the eth
tree instead.
The dial iterators of eth and snap now use the same DNS tree in the default configuration,
so both iterators should use the same DNS discovery client instance. This ensures that
the record cache and rate limit are shared. Records will not be requested multiple times.
While testing the change, I noticed that duplicate DNS requests do happen even
when the client instance is shared. This is because the two iterators request the tree
root, link tree root, and first levels of the tree in lockstep. To avoid this problem, the
change also adds a singleflight.Group instance in the client. When one iterator
attempts to resolve an entry which is already being resolved, the singleflight object
waits for the existing resolve call to finish and returns the entry to both places.
The new -limit option makes the filter operate on top N nodes by score.
This also adds ENR attribute stats in the nodeset info command.
Node set commands are now documented in README.
This change adds the --catalyst flag, enabling an RPC API for eth2 integration.
In this initial version, catalyst mode also disables all peer-to-peer networking.

This upgrades the cloudflare client dependency to v0.14.0. The new
version changes the API because all methods now require a context
parameter. This change also reduces the log level of the 'Skipping...'
message to debug, following a similar change in the AWS deployer.
The PR implements the --miner.notify.full flag that enables full pending block
notifications. When this flag is used, the block notifications sent to mining
endpoints contain the complete block header JSON instead of a work package
array.

* cmd/devp2p: fix comparison of TXT record value
The AWS API returns quoted DNS strings, so we must encode the new value
before comparing it against the existing record content.
* cmd/devp2p: add test
* cmd/devp2p: fix typo and rename val -> newValue
In Geth v1.10, we changed the structure of the "les" ENR entry. As a result, the DHT crawler that creates the DNS lists
no longer recognizes the les nodes, which is fixed in this commit.
* cmd/devp2p: skip ENR field tails properly in nodeset filter
* cmd/devp2p: fix tail decoder for snap as well
* les: fix tail decoding in "eth" ENR entry
This PR fixes a regression introduced in #22360, when we updated to the v2 of the AWS sdk, which causes current crawler to just get the same first 100 results over and over, and get stuck in a loop.
This updates the DNS deployer to use AWS SDK v2. Migration is relatively
seamless, although there were two locations that required a slightly
different approach to achieve the same results. In particular, waiting for
DNS change propagation is very different with SDK v2.
This change also optimizes DNS updates by publishing all changes before
waiting for propagation.
This PR fixes an issue with the eth66 test suite where, during a readAndServe when
the test is manually responding to GetBlockHeader requests, it now responds
with a BlockHeaders eth66 packet that includes the inbound request ID.
This replaces the github.com/pborman/uuid dependency with
github.com/google/uuid because the former is only a wrapper for
the latter (since v1.0.0).

This adds support for EIP-2718 typed transactions as well as EIP-2930
access list transactions (tx type 1). These EIPs are scheduled for the
Berlin fork.
There very few changes to existing APIs in core/types, and several new APIs
to deal with access list transactions. In particular, there are two new
constructor functions for transactions: types.NewTx and types.SignNewTx.
Since the canonical encoding of typed transactions is not RLP-compatible,
Transaction now has new methods for encoding and decoding: MarshalBinary
and UnmarshalBinary.
The existing EIP-155 signer does not support the new transaction types.
All code dealing with transaction signatures should be updated to use the
newer EIP-2930 signer. To make this easier for future updates, we have
added new constructor functions for types.Signer: types.LatestSigner and
types.LatestSignerForChainID.
This change also adds support for the YoloV3 testnet.

This PR adds a more CLI flag, so that the les-server can serve light clients even the local node is not synced yet.
This functionality is needed in some testing environments(e.g. hive). After launching the les server, no more blocks will be imported so the node is always marked as "non-synced".
This PR prevents users from submitting transactions without EIP-155 enabled. This behaviour can be overridden by specifying the flag --rpc.allow-unprotected-txs=true.
This PR introduces:
- db.put to put a value into the database
- db.get to read a value from the database
- db.delete to delete a value from the database
- db.stats to check compaction info from the database
- db.compact to trigger a db compaction
It also moves inspectdb to db.inspect.
This moves the eth config definition into a separate package, eth/ethconfig.
Packages eth and les can now import this common package instead of
importing eth from les, reducing dependencies.

This moves the tracing RPC API implementation to package eth/tracers.
By doing so, package eth no longer depends on tracing and the duktape JS engine.
The change also enables tracing using the light client. All tracing methods work with the

The duplication of this logic by MakeConsolePreloads

duplicate references to the assets dir path.

This PR adds support for using Twitter API to query the tweet and author details. There are two reasons behind this change:
- Twitter will be deprecating the legacy website on 15th December. The current method is expected to stop working then.
- More importantly, the current system uses Twitter handle for spam protection but the Twitter handle can be changed via automated calls. This allows bots to use the same tweet to withdraw funds infinite times as long as they keep changing their handle between every request. The Rinkeby as well as the Goerli faucet are being actively drained via this method. This PR changes the spam protection to be based on Twitter IDs instead of usernames. A user can not change their Twitter ID.

TAP is a text format for test results. Parsers for it are available in many languages,
making it easy to consume. I want TAP output from our protocol tests because the
Hive wrapper around them needs to know about the test names and their individual
results and logs. It would also be possible to just write this info as JSON, but I don't
want to invent a new format.
This also improves the normal console output for tests (when running without --tap).
It now prints -- RUN lines before any output from the test, and indents the log output
by one space.
The old one was wrong in two ways: the first block in chain.rlp was the
genesis block, and the genesis difficulty was below minimum difficulty.
This also contains some other fixes to the test.

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.
