This change adds support for blob-transaction in certain API-endpoints, e.g. eth_fillTransaction. A follow-up PR will add support for signing such transactions.
This change simplifies the logic for indexing transactions and enhances the UX when transaction is not found by returning more information to users.
Transaction indexing is now considered as a part of the initial sync, and `eth.syncing` will thus be `true` if transaction indexing is not yet finished. API consumers can use the syncing status to determine if the node is ready to serve users.
EIP-4844 adds a new transaction type for blobs. Users can submit such transactions via `eth_sendRawTransaction`. In this PR we refrain from adding support to `eth_sendTransaction` and in fact it will fail if the user passes in a blob hash.
However since the chain can handle such transactions it makes sense to allow simulating them. E.g. an L2 operator should be able to simulate submitting a rollup blob and updating the L2 state. Most methods that take in a transaction object should recognize blobs. The change boils down to adding `blobVersionedHashes` and `maxFeePerBlobGas` to `TransactionArgs`. In summary:
- `eth_sendTransaction`: will fail for blob txes
- `eth_signTransaction`: will fail for blob txes
The methods that sign txes does not, as of this PR, add support the for new EIP-4844 transaction types. Resuming the summary:
- `eth_sendRawTransaction`: can send blob txes
- `eth_fillTransaction`: will fill in a blob tx. Note: here we simply fill in normal transaction fields + possibly `maxFeePerBlobGas` when blobs are present. One can imagine a more elaborate set-up where users can submit blobs themselves and we fill in proofs and commitments and such. Left for future PRs if desired.
- `eth_call`: can simulate blob messages
- `eth_estimateGas`: blobs have no effect here. They have a separate unit of gas which is not tunable in the transaction.
* eth/gasestimator: early exit for plain transfer and error allowance
* core, eth/gasestimator: hard guess at a possible required gas
* internal/ethapi: update estimation tests with the error ratio
* eth/gasestimator: I hate you linter
* graphql: fix gas estimation test

* core/vm: set basefee to 0 internally on eth_call
* core: nicer 0-basefee, make it work for blob fees too
* internal/ethapi: make tests a bit more complex
* core: fix blob fee checker
* core: make code a bit more readable
* core: fix some test error strings
* core/vm: Get rid of weird comment
* core: dict wrong typo
So apparently in the spec the base block parameter of eth_call is optional.
I agree that "latest" is a sane default for this that most people would use.
The Go authors updated golang/x/ext to change the function signature of the slices sort method.
It's an entire shitshow now because x/ext is not tagged, so everyone's codebase just
picked a new version that some other dep depends on, causing our code to fail building.
This PR updates the dep on our code too and does all the refactorings to follow upstream...
This adds support for the "yParity" field in transaction objects returned by RPC
APIs. We somehow forgot to add this field even though it has been in the spec for
a long time.
* all: move main transaction pool into a subpool
* go.mod: remove superfluous updates
* core/txpool: review fixes, handle txs rejected by all subpools
* core/txpool: typos
Adds an optional config parameter to eth_call which allows users to override block context fields (same functionality that was added to traceCall in #24871)
