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.

Updates execution-spec-tests to 1.0.5: https://github.com/ethereum/execution-spec-tests/releases/tag/v1.0.5, switching to develop which contains Cancun tests (which are also enabled in this change).
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.
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. --------- Co-authored-by: Martin Holst Swende <martin@swende.se>
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.

…(#28381) This change to fixes a compilation-flaw on master, by putting architecture-specific functions behind corresponding build tags.
This change fixes a memory leak, when running either state-tests or blockchain-tests, we allocate a `1MB` fastcache during snapshot generation. `fastcache` is a bit special, and requires a `Reset()` (it has it's own memory allocator). The `1MB` was hidden [here](https://github.com/ethereum/go-ethereum/blob/master/tests/state_test_util.go#L333) and [here](https://github.com/ethereum/go-ethereum/blob/master/tests/block_test_util.go#L146) respectively.
Changes the trusted_setup to the one created during the kzg-ceremony. The trusted setup file can be found in the consensus specs: https://github.com/ethereum/consensus-specs/blob/dev/presets/mainnet/trusted_setups/trusted_setup_4096.json --------- Co-authored-by: Marius van der Wijden <m.vanderwijden@live.de>
…ds (#28359) 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.
Fixes a bug where the ethstats omits to report full block contents. This bug was a side-effect of ethereum/go-ethereum#26777, where `CurrentBlock` was changed to return a header instead of a block, leading to a failed type assertion.

There was a problem hiding this comment.
If goes to this line, thing goes wrong then. Is it possible that RawBid is a field of Bid but with lower case, so that we are not afraid that line 80 will happen?
