The oss-fuzz engine crashes due to stack overflow decoding a large nested
structure into a interface{}. This PR limits the size of the input data, so
should avoid such crashes.
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.
Previously on Geth startup we just logged the chain config is a semi-json-y format. Whilst that worked while we had a handful of hard-forks defined, currently it's kind of unwieldy.
This PR converts that original data dump and converts it into a user friendly - alas multiline - log output.
This adds the ability to run --state.fork=Merged, and have post-merge rules apply. When doing so, it also requires the input env to contain currentRandom, and enforces the currentDifficulty to be omitted or zero.
This adds a tools.go file to import all command packages used for
go:generate. Doing so makes it possible to execute go-based code
generators using 'go run', locking in the tool version using go.mod.

Trie tracer is an auxiliary tool to capture all deleted nodes
which can't be captured by trie.Committer. The deleted nodes
can be removed from the disk later.
This updates the no-cgo implementations in the crypto package to use
the github.com/btcsuite/btcd/btcec/v2 module instead of the older btcec
package that was part of the main github.com/btcsuite/btcd module.

This PR adds an addtional API called `NewBatchWithSize` for db
batcher. It turns out that leveldb batch memory allocation is
super inefficient. The main reason is the allocation step of
leveldb Batch is too small when the batch size is large. It can
take a few second to build a leveldb batch with 100MB size.
Luckily, leveldb also offers another API called MakeBatch which can
pre-allocate the memory area. So if the approximate size of batch is
known in advance, this API can be used in this case.
It's needed in new state scheme PR which needs to commit a batch of
trie nodes in a single batch. Implement the feature in a seperate PR.

This adds a check to verify that a sender-account does not have code, which means that the codehash is either `emptyCodeHash` _OR_ not present. The latter occurs IFF the sender did not previously exist, a situation which can only occur with zero cost gasprices.
This commit changes the behavior of BitCurve.Add to be more inline
with btcd. It fixes two different bugs:
1) When adding a point at infinity to another point, the other point
should be returned. While this is undefined behavior, it is better
to be more inline with the go standard library.
Thus (0,0) + (a, b) = (a,b)
2) Adding the same point to itself produced the point at infinity.
This is incorrect, now doubleJacobian is used to correctly calculate it.
Thus (a,b) + (a,b) == 2* (a,b) and not (0,0) anymore.
The change also adds a differential fuzzer for Add, testing it against btcd.
