Since these types were written, we've gained an executable spec:
https://github.com/ethereum/execution-specs
This PR aligns some of the types we use with this spec to simplify
comparisons and cross-referencing.
Using a `distinct` type is a tradeoff between nim ergonomics, type
safety and the ability to work around nim quirks and stdlib weaknesses.
In particular, it allows us to overload common functions such as `hash`
with correct and performant versions as well as maintain control over
string conversions etc at the cost of a little bit of ceremony when
instantiating them.
Apart from distinct byte types, `Hash32`, is introduced in lieu of the
existing `Hash256`, again aligning this commonly used type with the spec
which picks bytes rather than bits in the name.
Fixes a missing CancelledError async raising on discv5 waitMessage
which would cause "Error set on a non-raising future".
Also moves some more results import away from stew.
This allows for protocols build on top of discv5 to use the ENR
provided in the handshake directly, instead of having to rely
on requesting it from the discv5 routing table.
Currently only setting `--styleCheck:hint` as there are some
dependency fixes required and the compiler seems to trip over the
findnode MessageKind, findnode Message field and the findNode
proc. Also over protocol.Protocol usage.
toBytes for NodeId wasn't selected by compiler byt if it does
get selected, it will fail on the test cases due to the
countdown that is done in logDistance.
Set to toBytesBE properly now and do countup, that should make
it correct also for BE architecture.
Removed toBytes to avoid confusion and avoid this one being
selected ever. The only place toBytes for NodeId was used is in
sessions.nim makeKey func and there also the stint one
(thus native endianness) was selected in Nim 1.2.x.
Native endianness is fine there as it is only an internal
representation.
* Add build_dcli target and add it to CI
* Fix local imports for dcli
* And use local imports for all other files too
* Use local imports in tests and rlpx protocols
* use bearssl rng throughout
* seeder can fail
* imports and exports
* modules, sigh
* one more try
* move var
* even fewer thread vars
* remove out-of-date genrated files
* Discv5: More error handling improvements
- More results usage and raises pragma annotations
- Remove ENode related code and adjust Node object
- Misc.
* Add sendMessage and catch RlpError when decoding WhoAreYou
* Make the receive proc exception free
Except for `Exception` hah...
* Address review comments
* And another bunch of results and raises annotations
* Send Nodes Message also on 0 nodes and remove usage of broken require
