Reduce verbosity for InvalidCompilation errors

[DarkaMaul]

Following #2011

Problem

When trying to analyze a bogus Solidity file, slither output is a bit crowded with multiple stacktraces of exception thrown (as shown in the previous issue).

Tentative solution

If the compilation fails in Crytic with an InvalidCompilation exception, we don't print the backtrace and instead exit with a new error code (2).

The new output will be like this:

➜ slither Test.sol             
'solc --version' running
'solc Test.sol --combined-json abi,ast,bin,bin-runtime,srcmap,srcmap-runtime,userdoc,devdoc,hashes,compact-format --allow-paths .,./slither' running
Compilation warnings/errors on Test.sol:
Test.sol:2:1: Error: Source file requires different compiler version (current compiler is 0.5.1+commit.c8a2cb62.Darwin.appleclang - note that nightly builds are considered to be strictly less than the released version
pragma solidity ^0.9.0;
^---------------------^

ERROR:Slither:Unable to compile all targets.

A new test is added (maybe the location is wrong though) to test this behavior:

• Checks that error code is appropriate
• Checks that the logger output is correctly set

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

CodeRabbit Commands (invoked as PR comments)

• @coderabbitai pause to pause the reviews on a PR.
• @coderabbitai resume to resume the paused reviews.
• @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
