* Using unsigned types for message type and requst IDs
why:
Negative values are neither defined for RLP nor in the protocol specs
which refer to the RLPs (see yellow paper app B clause (199).
* Fix `int` argument (must be `uint`) in fuzzing tests
why:
Not part of all tests so it slipped through.
* Restricting exception catcher
why:
`CatchableError` is not needed here
* Check data length before converting to `openArray[]`
why:
Getting the first entry of an `openArray[]` crashes with `IndexDefect`.
This is particularly annoying when decoding messages in rlpx.
* Added unit test using rlpx message that causes this problem to detect
- Rework to have exception raise only at rlp decoding and use
result types from then onwards
- Adjust the current API to have result versions and deprecated
the ones which had var Record + bool
- Add PublickKey to the Record object, as this allows us to skip
fromRaw calls whenever access is needed to the public key
- Add a TypedRecord.fromRecord which cannot fail and deprecate
the old one
- Some other minor clean-up & re-ordering
- Rework adding and updating of fields by having an insert call
that gets used everywhere. Avoiding also duplicate keys. One
side-effect of this is that ENR sequence number will always get
updated on an update call, even if nothing changes.
- Deprecate initRecord as it is only used in tests and is flawed
- Assert when predefined keys go into the extra custom pairs.
Any of the predefined keys are only to be passed now via specific
parameters to make sure that the correct types are stored in ENR.
- Clearify the Opt.none behaviour for Record.update
- When setting ipv6, allow for tcp/udp port fields to be used
default
- General clean-up
- Rework/clean-up completely the ENR tests.
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.
* Fix chronos related deprecated warnings in discv5
* Fix chronos related deprecated warnings in uTP code
* Improve discv5 closeWait order of events and add noCancel
* Refactor p2pProtocol internals
* Attempt to fix rlp crash with Nim v2 (#658)
* Attempt to fix rlp crash with Nim v2
* Fix test_ecies for nim v2
* Reduce compiler warnings
* Resolve ambiquity in testutils
* Disable nim devel continue-on-error
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.
* Add metrics related to devp2p peer connections
* Avoid reconnecting to peers that just failed connection
- Add SeenTable to avoid reconnecting to peers immediately after
a failed connect. Depending on the failure, the amount of time is
different. This is similar to what is done in nimbus-eth2.
- Attempt to rework rlpxConnect at the same time, in order to
make sure that errors are properly handled. The current structure
is far from ideal, but it is hopefully a small step in the right
direction. To many oddities in there right now to really rework
rlpxConnect properply.
* Fix rlpx thunk fuzzer
The old code, which did it in sequence, made it take a very long
time to accumulate peers in the peer pool, particularly because
occasionally a connection-attempt would hang for a couple of minutes
before timing out.
