Prevent abort signals from causing uncaught exceptions

[nicktrn]

This prevents uncaught (and uncatchable!) exceptions by double and triple checking we haven't aborted yet, and also not using aborts in some cases. There's also more logging in case this causes issues again.

Walkthrough

The changes introduce a new error class, CheckpointAbortError, to manage abort scenarios in the Checkpointer class. The aborting logic has been refined to prevent redundant abort attempts by checking the state of the abort controller's signal. A helper function, assertNotAborted, has been added to streamline abort checks and throw the new error when needed. Additionally, the error handling in the existing try-catch block has been updated to differentiate between general errors and CheckpointAbortError, enhancing log clarity during checkpoint cancellations.

Changes

File Path	Change Summary

Poem

In the meadow where bunnies hop,
A new error class makes our hearts stop.
With checkpoints now clear, no more to fret,
Abort signals handled, no need to sweat!
So let’s dance and cheer, for the code is bright,
A hop, a skip, everything feels just right! 🐇✨

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>, please review it.
  -- 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 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.
  -- @coderabbitai help me debug CodeRabbit configuration file.

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.
