fix: fix slice init length #254

Open wangjingcun opened 1 day ago

wangjingcun commented 1 day ago

The intention here should be to initialize a slice with a capacity of 2 rather than initializing the length of this slice.

Summary by CodeRabbit

coderabbitai[bot] commented 1 day ago

Walkthrough

The changes involve a modification to the TestLoadTokensFromUrl function in the client/core/tokens_file_loader_test.go file. The initialization of the tokensMetadata slice has been altered to allow for dynamic growth by changing its creation from a fixed length of 2 to a length of 0 with a capacity of 2. This adjustment does not affect the logic or assertions of the existing tests, which continue to validate the functionality of the LoadTokens function.

Changes

File Change Summary
client/core/tokens_file_loader_test.go Modified TestLoadTokensFromUrl to initialize tokensMetadata with length 0 and capacity 2 for dynamic growth. No changes to logic or assertions in tests.

Poem

In the code where tokens play,
A slice was changed in a clever way.
With room to grow, it leaps and bounds,
In tests, the right behavior founds.
Hooray for tweaks that make it bright,
Our tokens dance in code's delight! 🐇✨

`14-14`: **LGTM! Good optimization of slice initialization.** The change from `make([]TokenMetadata, 2)` to `make([]TokenMetadata, 0, 2)` is a correct optimization. The original code pre-allocated two zero-value `TokenMetadata` structs that were immediately overwritten by the `append` operations. The new code allocates the capacity but starts with zero length, which is more efficient since we're using `append` to add the actual values.

🪧 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 , 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. ### 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. ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
