Decoding events and fetching past events is failing with an UnhandledPromiseRejectionWarning:

[GriffGreen]

Have been hoping around from a few ethereum libraries... but we are thinking that the ABI-decoder is the issue.

Previous issues
web3/web3.js#3671
Consensys/abi-decoder#56
are summarized below

It seems that the ConsenSys abi-decoder calls web3.js but in the end uses the ethers.js abi decoder... cause well.... you guys rock ;-)

System information

Geth version: geth version 1.9.18-stable
OS & Version: Linux
Commit hash : (Infura and Aragon gateway)

Expected behavior

Decoding events/logs and fetching past events just works

Actual behavior

For years we were able to decode data for events and then about a week ago it just stopped working... now we get an error

Steps to reproduce the behavior

The decode function produces this error message on decoding data:
(node:55476) UnhandledPromiseRejectionWarning: Error: data out-of-bounds (length=164, offset=192, code=BUFFER_OVERRUN, version=abi/5.0.0-beta.153)

We modified the log data and filled it with zero value except for the part I needed and the code works as before.

It's the code that has been modified if you remove the part that modifies the log.data the error appears

https://github.com/Giveth/feathers-giveth/blob/b164131e588f640a8bd83136ad6c867fb7b6733b/scripts/utils/getHomeTxHash.js#L27-L55

This is the smart contract code and abi: https://rinkeby.etherscan.io/address/0xff9cd5140e79377feb23f6dfaf1f8b558c0fe621#code

And we tried to decode the log data of this transaction: https://rinkeby.etherscan.io/tx/0xa20e3db910d95a5a23692eef523bd6e98152d4759782e6097d3f6eaccf17ff46

Environment
Node v8.17.0
Web3 1.2.11
OS Linux and MacOS

This is the a sample code to regenerate the error:

const abiDecoder = require('abi-decoder'); // NodeJS
const Web3 = require('web3');

[GriffGreen]

This fixes the problem by appending a bunch of 0's to the end of the data

function eventDecodersFromArtifact(artifact) {
  return artifact.compilerOutput.abi
    .filter(method => method.type === 'event')
    .reduce(
      (decoders, event) => ({
        ...decoders,
        [event.name]: log => {
          const decoder = Contract.prototype._decodeEventABI.bind(event);
          log.data += '0'.repeat(100);
          return decoder(log);
        },
      }),
      {},
    );
}

[dapplion]

I believe the cause of the issue is a check on Reader.prototype._peekBytes. This assertion is not true for the event being parsed, where the variable data bytes is an encoded function call where not all words are 32 bytes.

ethers.js/packages/abi/src.ts/coders/abstract-coder.ts

Lines 163 to 172 in 9640e86

	_peekBytes(offset: number, length: number): Uint8Array {
	let alignedLength = Math.ceil(length / this.wordSize) * this.wordSize;
	if (this._offset + alignedLength > this._data.length) {
	logger.throwError("data out-of-bounds", Logger.errors.BUFFER_OVERRUN, {
	length: this._data.length,
	offset: this._offset + alignedLength
	});
	}
	return this._data.slice(this._offset, this._offset + alignedLength)
	}

To recreate use this event which I've commented for ease of following

Why is that check necessary in this context?

[ricmoo]

Is it possibly this is related to this issue?

Are the invalid logs coming for Solidity 4.x where the function was marked as "external" (opposed to "public", which works fine)?

[ricmoo]

The above data you gave looks wrong (just by eye; I’m still in bed reading this ;)), but every slot should be 32 bytes long. The 4c4316c7 is missing 28 null bytes (56 zero nibble) after it.

The old decided did not do this check, so it was possibly to overrun into subsequent data, luckily it got trimmed off. But it may be possible for wrong data to be emitted as a result. I need to do some research into this though.

It is a known bug in Solidity though, and they fixed it in 5. I’m considering adding a recovery mode for bad events, but if you have some examples of transactions with these bad entries that would help.

The biggest issue with trying to solve this is it produces content that cannot be earablished as an error or not. Content that is congruent (in length) to 0 mod 32 bytes is a success, anything congruent to 4 mod 32 is an error. With the old coder, it would emit data you expect to be an error (4 mod 32), which ethers will throw a CALL_EXCEPTION for, but for which the contract believed it was doing the correct thing.

So if there was a way to allow a non-strict parsing, you would lose the ability to detect revert reasons. In fact, it would be non-deterministic; you may not detect an error when there was one and you may get data out when there was an error, with some non-trivial probability (off the top of my head this could happen as much as 3% of the time).

I think. :)

If I understand the issue correctly. :)

[dapplion]

@ricmoo The data of the example was pulled from this actual transaction https://rinkeby.etherscan.io/tx/0xa20e3db910d95a5a23692eef523bd6e98152d4759782e6097d3f6eaccf17ff46#eventlog logIndex 5. bytes is of arbitrary length, in this case, crafted by a Bridge application so it's not forced to pad the bytes words to 32 bytes. Should it?

[ricmoo]

@dapplion yes, the bytes must be padded to be a multiple of 32 bytes.

There is a known Solidity v4.x bug that events emitted from an external (public is fine) function in Solidity that dynamic objects are encoded incorrectly. If you look at line 1075 in the contract for the transaction you provided, the function is marked external and it is from an affected version of the compiler.

This is a compiler bug which makes it very hard to work around. :(

The work around for it can break correctly functioning contracts, which is the problem. We can possibly use a modified version of the coder (or pass a flag in) for events that allows looser checks, but which might allow corrupt data to be emitted and can certainly not be used for generating encoded data passed into solidity as that could result in completely corrupt execution. It’s a sticky sitch. :s

[ricmoo]

Here is another link with more info: web3/web3.js#3544

[dapplion]

After reading the referenced issues from June is there a roadmap to allow corrupted events to be parsed somehow?

The above code sample throws the above mentioned error on ethers version 5.0.8.
But works correctly when version 4.0.47 of ethers package is used!
