[!WARNING]

Rate limit exceeded

@sideninja has exceeded the limit for the number of commits or files that can be reviewed per hour. Please wait 11 minutes and 34 seconds before requesting another review.

How to resolve this issue? After the wait time has elapsed, a review can be triggered using the `@coderabbitai review` command as a PR comment. Alternatively, push new commits to this PR. We recommend that you space out your commits to avoid hitting the rate limit.
How do rate limits work? CodeRabbit enforces hourly rate limits for each developer per organization. Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout. Please see our [FAQ](https://coderabbit.ai/docs/faq) for further information.

Walkthrough

The changes introduce a caching mechanism to the Requester service, which enhances the efficiency of script execution. A new type, scriptType, categorizes script operations, and a map associates these types with their bytecode. The EVM struct now includes a scriptCache field that utilizes an LRU cache. The executeScriptAtHeight method is refactored to leverage this cache, optimizing performance by reducing redundant executions and improving error handling.

Changes

Files Change Summary
config/config.go Added CacheSize field to Config struct and updated FromFlags function to include a command-line flag for cache size.
services/requester/requester.go Introduced caching mechanism, defined scriptType, added scripts map, modified EVM struct with scriptCache, and refactored executeScriptAtHeight.
services/requester/requester_test.go Added unit tests for caching functionality, including tests for cache behavior at specific heights and cache expiry. New functions for testing cache key generation included.

Poem

🐰
In the meadow where scripts do play,
A cache was built to save the day.
With types and maps, oh what a sight,
Efficiency hops, taking flight!
No more waits, just swift delight,
Thank you, dear code, for making it right!

Tips ### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `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.` - `@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 using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
