- add comments to hashes shim
- remove .catch from callback condition
- derive SignerError from EthersError instead of ProviderError. This allows Providers and Signers to be separate, as Ledger does it, to isolate functionality. Some signer functions now raise both ProviderError and SignerError
- Update reverts to check for SignerError
- Update ERC-20 method comment
Fixes issue where getAddress and sendTransaction could not be found for MockSigner in tests. The problem was that the async: raises update had not been applied to the MockSigner.
next step is to:
1. change back any ethers var names that were changed for serialization purposes, eg `from` and `type`
2. move the json util to its own lib
- signer procs raise SignerError, provider procs raise ProviderError
- WalletError now inherits from SignerError
- move wallet module under signers
- create jsonrpo moudle under signers
- bump nim-json-rpc for null-handling fixes
- All jsonrpc provider tests passing, still need to fix others
- async lock during nonce sequencing + gas estimation
- simplified cancelTransaction (still exported) such that the new transaction is populated using populateTransaction, so that all gas and fees are reset
- moved reverting contract function into its own testing helpers module, and refactored any tests to use it
- updated the test helper reverts to check EstimateGasErrors
- combine ensureNonceSequence into populateTransaction
Based on ethers.js's queryFilter, allows querying of past contract events, by querying the logs for a contract's event topic.
* queryFilter to query past logs
* Allow querying of past block log events
* Can query by block number or block hash
Add support for indexed (and non-indexed) Event fields types that are distinct `ValueType` or `SmallByteArray`. For example,
```nim
type
DistinctAlias = distinct array[32, byte]
MyEvent = object of Event
a {.indexed.}: DistinctAlias
b: DistinctAlias # also allowed for non-indexed fields
## The below funcs generally need to be included for ABI
## encoding/decoding purposes when implementing distinct types.
func toArray(value: DistinctAlias): array[32, byte] =
array[32, byte](value)
func encode*(encoder: var AbiEncoder, value: DistinctAlias) =
encoder.write(value.toArray)
func decode*(decoder: var AbiDecoder,
T: type DistinctAlias): ?!T =
let d = ?decoder.read(type array[32, byte])
success DistinctAlias(d)
```
