Better handling for cache key errors

[damianhxy]

When loading tokens from the .arcache fails, proactively delete the file, so that the user is forced to set-up the CLI again.

Also, remove grading_deadline logic.

Closes #23

To test:

• Set up autolab CLI (in debug mode)
• Try loading an assessment, make sure there no string_to_time parse fail! messages (previously caused by attempting to parse grading_deadline)
• Ensure that .autolab/.arcache file exists in user home directory
• Update crypto_key in app_credentials.h, and rebuild CLI
• Try loading an assessment again, get error message

• Check that .autolab/.arcache file has been removed
• Try loading an assessment again - no more error about load_tokens

Walkthrough

Walkthrough

The recent updates primarily enhance error handling and code consistency in the Autolab system. Key modifications include the removal of the grading_deadline field from the Assessment struct, improved exception handling with std::move and noexcept, and the introduction of a CryptoException class for better encryption error management. Additionally, file operations in the context manager now handle crypto exceptions, and the crypto module's error handling is refined to throw exceptions instead of exiting.

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.

verified that ignoring cache on crypto error works by recreating the error found with autolab V3 on AFS, setup now works without having to manually delete the cache. LGTM besides logging comment.
