This change adds a code generator tool for creating EncodeRLP method
implementations. The generated methods will behave identically to the
reflect-based encoder, but run faster because there is no reflection overhead.
Package rlp now provides the EncoderBuffer type for incremental encoding. This
is used by generated code, but the new methods can also be useful for
hand-written encoders.
There is also experimental support for generating DecodeRLP, and some new
methods have been added to the existing Stream type to support this. Creating
decoders with rlpgen is not recommended at this time because the generated
methods create very poor error reporting.
More detail about package rlp changes:
* rlp: externalize struct field processing / validation
This adds a new package, rlp/internal/rlpstruct, in preparation for the
RLP encoder generator.
I think the struct field rules are subtle enough to warrant extracting
this into their own package, even though it means that a bunch of
adapter code is needed for converting to/from rlpstruct.Type.
* rlp: add more decoder methods (for rlpgen)
This adds new methods on rlp.Stream:
- Uint64, Uint32, Uint16, Uint8, BigInt
- ReadBytes for decoding into []byte
- MoreDataInList - useful for optional list elements
* rlp: expose encoder buffer (for rlpgen)
This exposes the internal encoder buffer type for use in EncodeRLP
implementations.
The new EncoderBuffer type is a sort-of 'opaque handle' for a pointer to
encBuffer. It is implemented this way to ensure the global encBuffer pool
is handled correctly.
* internal: support optional filter expression for debug.stacks
* internal/debug: fix string regexp
* internal/debug: support searching for line numbers too
This PR adds flag to enable InfluxDB v2 (--metrics.influxdbv2), flags for v2-specific features (--metrics.influxdb.token, --metrics.influxdb.bucket), also carries over addition of support for specifying organization (--metrics.influxdb.organization), but still retains backwards compatibility with InfluxDB v1.
This removes auto-configuration of the snap.*.ethdisco.net DNS discovery tree.
Since measurements have shown that > 75% of nodes in all.*.ethdisco.net support
snap, we have decided to retire the dedicated index for snap and just use the eth
tree instead.
The dial iterators of eth and snap now use the same DNS tree in the default configuration,
so both iterators should use the same DNS discovery client instance. This ensures that
the record cache and rate limit are shared. Records will not be requested multiple times.
While testing the change, I noticed that duplicate DNS requests do happen even
when the client instance is shared. This is because the two iterators request the tree
root, link tree root, and first levels of the tree in lockstep. To avoid this problem, the
change also adds a singleflight.Group instance in the client. When one iterator
attempts to resolve an entry which is already being resolved, the singleflight object
waits for the existing resolve call to finish and returns the entry to both places.
This upgrades the cloudflare client dependency to v0.14.0. The new
version changes the API because all methods now require a context
parameter. This change also reduces the log level of the 'Skipping...'
message to debug, following a similar change in the AWS deployer.
This updates the DNS deployer to use AWS SDK v2. Migration is relatively
seamless, although there were two locations that required a slightly
different approach to achieve the same results. In particular, waiting for
DNS change propagation is very different with SDK v2.
This change also optimizes DNS updates by publishing all changes before
waiting for propagation.
This replaces the github.com/pborman/uuid dependency with
github.com/google/uuid because the former is only a wrapper for
the latter (since v1.0.0).

This change allows users to set a custom path prefix on which to mount the http-rpc
or ws-rpc handlers via the new flags --http.rpcprefix and --ws.rpcprefix.

* accounts/scwallet: use go-ethereum crypto instead of go-ecdh
github.com/wsddn/go-ecdh is a wrapper package for ECDH functionality
with any elliptic curve.
Since 'generic' ECDH is not required in accounts/scwallet (the curve is
always secp256k1), we can just use the standard library functionality
and our own crypto libraries to perform ECDH and save a dependency.
* Update accounts/scwallet/securechannel.go

This adds a test suite for discovery v4. The test suite is a port of the Hive suite for
discovery, and will replace the current suite on Hive soon-ish. The tests can be
run locally with this command:
devp2p discv4 test -remote enode//...
