[ymc9]

Fixes #1533

[coderabbitai]

Walkthrough

Walkthrough

The code changes introduce a new clone function within the cross module, replacing all instances of the deepcopy function in various files for deep cloning arrays and objects. Additionally, a safeClone method has been introduced in policy-utils.ts. A regression test addressing issue #1533 was also added to validate searches for null values and attributes in JSON fields.

Changes

Files	Summary
packages/runtime/src/cross/clone.ts	Introduced a new clone function for deep cloning arrays and objects.
packages/runtime/src/cross/index.ts	Added export for the clone function.
packages/runtime/src/cross/mutator.ts, packages/runtime/src/enhancements/default-auth.ts, packages/runtime/src/enhancements/delegate.ts, packages/runtime/src/enhancements/proxy.ts	Replaced deepcopy with clone in multiple modules for consistent cloning behavior.
packages/runtime/src/enhancements/policy/handler.ts, packages/runtime/src/enhancements/policy/policy-utils.ts	Removed old clone method and introduced safeClone for cloning operations in policy enhancements.
packages/runtime/src/enhancements/utils.ts	Removed the old clone function using deepcopy.
tests/regression/tests/issue-1533.test.ts	Added regression test to validate JSON field checks for null values and attribute existence, addressing issue #1533.

Assessment against linked issues

Early access features: enabled

We are currently testing the following features in early access:

• OpenAI gpt-4o model for code reviews and chat: OpenAI claims that this model is better at understanding and generating code than the previous models. We seek your feedback over the next few weeks before making it generally available.

Note:

• You can enable or disable early access features from the CodeRabbit UI or by updating the CodeRabbit configuration file.
• Please join our Discord Community to provide feedback and report issues.
• OSS projects are always opted into early access features.

Thank you for using CodeRabbit. We offer it for free to the OSS community and would appreciate your support in helping us grow. If you find it useful, would you consider giving us a shout-out on your favorite social media?

Tips

Chat

There are 3 ways to chat with CodeRabbit:

‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

• 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.
  • @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.

CodeRabbit Commands (invoked as PR comments)
