This PR removes the newly added txpool.Transaction wrapper type, and instead adds a way
of keeping the blob sidecar within types.Transaction. It's better this way because most
code in go-ethereum does not care about blob transactions, and probably never will. This
will start mattering especially on the client side of RPC, where all APIs are based on
types.Transaction. Users need to be able to use the same signing flows they already
have.
However, since blobs are only allowed in some places but not others, we will now need to
add checks to avoid creating invalid blocks. I'm still trying to figure out the best place
to do some of these. The way I have it currently is as follows:
- In block validation (import), txs are verified not to have a blob sidecar.
- In miner, we strip off the sidecar when committing the transaction into the block.
- In TxPool validation, txs must have a sidecar to be added into the blobpool.
- Note there is a special case here: when transactions are re-added because of a chain
reorg, we cannot use the transactions gathered from the old chain blocks as-is,
because they will be missing their blobs. This was previously handled by storing the
blobs into the 'blobpool limbo'. The code has now changed to store the full
transaction in the limbo instead, but it might be confusing for code readers why we're
not simply adding the types.Transaction we already have.
Code changes summary:
- txpool.Transaction removed and all uses replaced by types.Transaction again
- blobpool now stores types.Transaction instead of defining its own blobTx format for storage
- the blobpool limbo now stores types.Transaction instead of storing only the blobs
- checks to validate the presence/absence of the blob sidecar added in certain critical places
* core/blobpool: implement txpool for blob txs
* core/txpool: track address reservations to notice any weird bugs
* core/txpool/blobpool: add support for in-memory operation for tests
* core/txpool/blobpool: fix heap updating after SetGasTip if account is evicted
* core/txpool/blobpool: fix eviction order if cheap leading txs are included
* core/txpool/blobpool: add note as to why the eviction fields are not inited in reinject
* go.mod: pull in inmem billy form upstream
* core/txpool/blobpool: fix review commens
* core/txpool/blobpool: make heap and heap test deterministic
* core/txpool/blobpool: luv u linter
* core/txpool: limit blob transactions to 16 per account
* core/txpool/blobpool: fix rebase errors
* core/txpool/blobpool: luv you linter
* go.mod: revert some strange crypto package dep updates
This change ensures Reheap will be called even before the London fork activates.
Since Reheap would otherwise only be called through `SetBaseFee` after London,
the list would just keep growing if the fork was not enabled or not reached yet.
* 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
* core/txpool: abstraction prep work for secondary pools (blob pool)
* core/txpool: leave subpool concepts to a followup pr
* les: fix tests using hard coded errors
* core/txpool: use bitmaps instead of maps for tx type filtering
Prior to this change, it was possible that transactions are erroneously deemed as 'future' although they are in fact 'pending', causing them to be dropped due to 'future' not being allowed to replace 'pending'.
This change fixes that, by doing a more in-depth inspection of the queue.
Currently, most of transaction validation while holding the txpool mutex: one exception being an early-on signature check.
This PR changes that, so that we do all non-stateful checks before we entering the mutex area. This means they can be performed in parallel, and to enable that, certain fields have been made atomic bools and uint64.
This adds two new rules to the transaction pool:
- A future transaction can not evict a pending transaction.
- A transaction can not overspend available funds of a sender.

This PR changes the API so that uint64 is used for fork timestamps.
It's a good choice because types.Header also uses uint64 for time.

This enables the following linters
- typecheck
- unused
- staticcheck
- bidichk
- durationcheck
- exportloopref
- gosec
WIth a few exceptions.
- We use a deprecated protobuf in trezor. I didn't want to mess with that, since I cannot meaningfully test any changes there.
- The deprecated TypeMux is used in a few places still, so the warning for it is silenced for now.
- Using string type in context.WithValue is apparently wrong, one should use a custom type, to prevent collisions between different places in the hierarchy of callers. That should be fixed at some point, but may require some attention.
- The warnings for using weak random generator are squashed, since we use a lot of random without need for cryptographic guarantees.
The price limit is supposed to exclude transactions with too low fee
amount. Before EIP-1559, it was sufficient to check the limit against
the gas price of the transaction. After 1559, it is more complicated
because the concept of 'transaction gas price' does not really exist.
When mining, the price limit is used to exclude transactions below a
certain effective fee amount. This change makes it apply the same check
earlier, in tx validation. Transactions below the specified fee amount
cannot enter the pool.
