Currently, one can use the "withLogs" parameter to include logs in the
callTracer results, which allows the user to see at which trace level
was each log emitted.
This commit adds a position field to the logs which determine
the exact ordering of a call's logs and its subcalls. This would
be useful e.g. for explorers wishing to display the flow of execution.

This change improves GenerateChain to support internal chain history access (ChainReader)
for the consensus engine and EVM.
GenerateChain takes a `parent` block and the number of blocks to create. With my changes,
the consensus engine and EVM can now access blocks from `parent` up to the block currently
being generated. This is required to make the BLOCKHASH instruction work, and also needed
to create real clique chains. Clique uses chain history to figure out if the current signer is in-turn,
for example.
I've also added some more accessors to BlockGen. These are helpful when creating transactions:
- g.Signer returns a signer instance for the current block
- g.Difficulty returns the current block difficulty
- g.Gas returns the remaining gas amount
Another fix in this commit concerns the receipts returned by GenerateChain. The receipts now
have properly derived fields (BlockHash, etc.) and should generally match what would be
returned by the RPC API.
This adds warning logs when the read does not match the expected count.
We can also remove the size limit since the function documentation explicitly states
that callers should limit the count.

We have this dependency on docker, a.k.a moby: a gigantic library, and we only need ~70 LOC,
so here I tried moving it inline instead.

This PR is a bit in preparation for the slog work in #28187 .
Our current test re logging mostly test the internals, but we have no real end-to-end test of the logging output. This PR introduces a simple reexec-based log tester. This also relies upon a special mode in geth, which can be made to eject a set of predefined log messages (only available if the build-tag `integrationtests` is used
e.g. go run --tags=integrationtests ./cmd/geth --log.format terminal logtest
While working on this, I also noticed a quirk in the setup: when geth was configured to use a file output, then two separate handlers were used (one handler for the file, one handler for the console). Using two separate handlers means that two formatters are used, thus the formatting of any/all records happened twice. This PR changes the mechanism to use two separate io.Writers instead, which is both more optimal and fixes a bug which occurs due to a global statefulness in the formatter.
The String() version of BlockNumberOrHash uses decimal for all block numbers, including negative ones used to indicate labels. Switch to using BlockNumber.String() which encodes it correctly for use in the JSON-RPC API.
This PR removes panics from stacktrie (mostly), and makes the Update return errors instead. While adding tests for this, I also found that one case of possible corruption was not caught, which is now fixed.
This change closes https://github.com/ethereum/go-ethereum/issues/27730 . By using an iterator instead of a slice of transactions, we can better handle the case when an individual transaction (within an otherwise well-formed RLP-list) cannot be decoded.
Fixes a bug where the ethstats omits to report full block contents. This bug was a side-effect of https://github.com/ethereum/go-ethereum/pull/26777, where `CurrentBlock` was changed to return a header instead of a block, leading to a failed type assertion.
A goroutine is used to manage the lifetime of subscriptions managed by
resubscriptions. When the subscription ends with no error, the resub
goroutine ends as well. However, the resub goroutine needs to live
long enough to read from the unsub channel. Otheriwse, an Unsubscribe
call deadlocks when writing to the unsub channel.
This is fixed by adding a buffer to the unsub channel.
* api/bind: Add CallOpts.BlockHash to allow calling contracts at a specific block hash.
* ethclient: Add BalanceAtHash, NonceAtHash and StorageAtHash functions
This change enhances the stacktrie constructor by introducing an option struct. It also simplifies the `Hash` and `Commit` operations, getting rid of the special handling round root node.
This changes fixes a bug in the fetcher, where the timeout for how long to remember underpriced transaction was erroneously compared, and the timeout never hit.

This change fixes#28355, where eth_getProof failed to return the correct codehash under certain conditions. This PR changes the logic to unconditionally look up the codehash, and also adds some more tests.
During snap-sync, we request ranges of values: either a range of accounts or a range of storage values. For any large trie, e.g. the main account trie or a large storage trie, we cannot fetch everything at once.
Short version; we split it up and request in multiple stages. To do so, we use an origin field, to say "Give me all storage key/values where key > 0x20000000000000000". When the server fulfils this, the server provides the first key after origin, let's say 0x2e030000000000000 -- never providing the exact origin. However, the client-side needs to be able to verify that the 0x2e03.. indeed is the first one after 0x2000.., and therefore the attached proof concerns the origin, not the first key.
So, short-short version: the left-hand side of the proof relates to the origin, and is free-standing from the first leaf.
On the other hand, (pun intended), the right-hand side, there's no such 'gap' between "along what path does the proof walk" and the last provided leaf. The proof must prove the last element (unless there are no elements).
Therefore, we can simplify the semantics for trie.VerifyRangeProof by removing an argument. This doesn't make much difference in practice, but makes it so that we can remove some tests. The reason I am raising this is that the upcoming stacktrie-based verifier does not support such fancy features as standalone right-hand borders.
