Walkthrough

The changes introduce enhancements to the GithubTool class by adding token management and improving error handling. A new class variable stores GitHub tokens, and an initialize_tokens method populates it from an environment variable. Additionally, a get_public_github_instance method retrieves a random token to create a GitHub client. The _get_github_client method now attempts an authenticated repository access and, upon failure, logs the error and tries public access. Import statements were updated to support the new functionality.

Changes

File Changes Summary
app/.../github_tool.py • Added gh_token_list: List[str] to store tokens
• Introduced initialize_tokens to load tokens from the environment
• Added get_public_github_instance to retrieve a random token and create a client
• Enhanced _get_github_client to log errors and try public access upon failure
• Updated imports to include random and List

Poem

Oh, what a hop, what a clever tweak,
Tokens line up in a charming streak.
From env they leap with a random spin,
Making GitHub access a win-win.
A happy rabbit hops with a grin! 🐇

Code transforms with a joyful beat!

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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @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.

50-60: Ensure robust handling of token availability.
Raising a ValueError upon an empty token string is valid for fail-fast behavior. However, consider whether there's a fallback or a more graceful strategy if production workloads rely on partial functionality in the absence of tokens.


90-96: Random selection of tokens is acceptable but consider usage distribution.
Selecting tokens at random could cause uneven token usage under high load. Consider round-robin or tracking usage to balance rate limits across tokens.


120-120: Address PEP 8 code formatting.
The pipeline flagged a formatting issue here. Please run a code formatter (e.g., Black) to resolve styling noncompliance.

122-129: Chain the raised exception to the original error.
Per [B904], it’s recommended to use raise ... from public_error to preserve the error context.

Apply this diff for clarity:

-            raise Exception(f"Repository {repo_name} not found or inaccessible on GitHub")
+            raise Exception(f"Repository {repo_name} not found or inaccessible on GitHub") from public_error

4-6: No immediate concerns; usage of random and List looks correct.
These imports are fine for the newly introduced functionality.


48-48: No changed code on this line.


65-66: Deferred token initialization is valid.
This lazy initialization ensures tokens are populated before first use.


238-238: No functional changes; finalize code formatting.
Re-running black or a similar formatter is recommended for consistent styling.

⚠️ Potential issue

Avoid embedding sensitive private key data within code.
Static analysis flagged a private key in these lines. Even though you partially construct it using config_provider, storing or reconstructing private keys in code can pose a security risk. Consider storing the entire key in a secure external location or environment variable to reduce the risk of accidental disclosure.
