Description

Suppose I try to compile the following contract:

//SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract Repro {
  function run() public pure returns (string memory) {
    return "¡¡¡";
  }
}

I get the following error message:

ParserError: Invalid character in string.
 --> project:/contracts/Repro.sol:6:12:

6 |     return "¡¡

The backup storage format being defined very simple and dumb, which is expected, there are a few bad cases people need to be careful with.

1. on the backup side, two backup coordinators can run at the same time and write to the storage at the same time, creating duplicate, or even worse, conflicting (if the two coordinators read different chains) backups.
2. on the "read" side, backup CLI tool

When deploying fabric in enterprise's intranet (without the ability to access internet), users maybe upload chaincode builder images and chaincode runtime images to a private docker registry which requires authentication when pulling images.
I think fabric can support this scenario by adding configuration in chaincode section of core.yaml, such as:

chaincode:
    registry:
        

Feature

Similar to #4461, it would be nice if people could truffle exec typescript without needing to run a compilation step.

Steps to Reproduce

Write a script for truffle exec in TypeScript

Desired Behavior

Truffle would use ts-node to execute said script

Current Behavior

Users must first compile said script, and truffle exec the compilation output.

Problem

isBlockhashValid is a useful RPC call for checking if a transaction needs to be resigned with a new blockhash, but it isn't available in web3.js

Proposed Solution

Add support for it on Connection. More information about the call at https://docs.solana.com/developing/clients/jsonrpc-api#isblockhashvalid

Creating a new issue based on lbryio/lbry-sdk#877

• Update ensure_directory_exists() to check that the directory is writable by the current process.
• If it's not, return a useful error
• Add tests to cover the case when
  • download directory does not exist
  • download dir exists but is not writable
  • dir exists an

Background

Inspired by C-Otto/rebalance-lnd#241.

As part of pathfinding, lnd might encounter edges that have a policy specifying a zero CLTV delta (possibly because of no/outdated gossip?). Every time an edge like this is used in the pathfinding code, a warning is logged: https://github.com/lightningnetwork/lnd/blob/290b78e700021e238f7e6bdce6acc80de8d0a64f/routi

A parametrized option to set the blocksize would be useful to experiment with. As quorum is used in a private setting I think this option should be available

Issue Description

The instructions provided on failed jobs (example) don't clearly explain where to find the generated patch file. This can be a problem for anyone who is not familiar with how Github Actions pages are organized.

The general idea is:

From the details page, click on "Summary", then scroll down to the "Artifacts" secti
