* 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
Other implementations of MPT delete entries when attempting to put empty
value, because empty value cannot exist in RLP. We should match the
behaviour.
- https://github.com/ethereum/py-trie/pull/109
Also cross-checked with Geth and Ethereumjs implementations.
- 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.
We don't need to clear keccak context after hashing ethereum data since
it is already public - similar to
https://github.com/status-im/nimbus-eth2/pull/222.
Because we overwrite the result fully, we also don't need to zero first.
* Revert "In the incomplete-db node-existence check, don't use contains. (#603)"
This reverts commit 4b818e8307.
* Revert "Some changes to make hexary.nim better able to handle incomplete DBs (#602)"
This reverts commit f5dd26eac0.
* Revert "Added maybeGet, for working with incomplete DBs. (#595)"
This reverts commit 4754543605.
A first step in cleaning up RLP, which has lots of interesting issues -
the next step would be to clean up the exception handling as well
(Resultify?)
* remove `RlpNode` (unused)
* single-pass parsing for most functionality via RlpItem
* stricter conformance to spec
* remove float support
* warn about signed integers
* raise on invalid RLP earlier
* avoid several pointless allocations, in particular in `listLen`,
`listElem` etc
* include spec docs
EIP-4844 blob sidecars are a concept that only exists in the mempool.
After inclusion of a transaction into an execution block, only the
versioned hash within the transaction remains. To improve type safety,
replace the `Transaction.networkPayload` member with a wrapper type
`PooledTransaction` that is used in contexts where blob sidecars exist.
Suppresses an annoying hint that gets triggered when `params is tuple`
but it's an empty tuple without fields.
```
Hint: 'i' is declared but not used [XDeclaredButNotUsed]
```
1. Fix Assertion error when receipt is not a List nor has a single
byte value. Receiving such garbage data would cause a crash.
2. Fix decoding of Receipt list by adding the missing Blob
encapsulation
Also added tests for these scenarios.
This also makes the uTP SendCallBack not returning a Future any
more as it is not used in sendData anyhow. And in case of uTP
over discv5, discv5 send call is already not async.
This gives quite a noticable throughput benchmark improvement over
with uTP over UDP, and a slightly noticable with uTP over discv5
