Walkthrough

This change set introduces a new fulltext indexing feature leveraging the Tantivy search engine. It includes configuration, creation, and error handling functionalities. Dependencies such as serde, tokio, and tantivy are added to support these features. Additionally, some minor corrections in variable names and consistency adjustments are made in the puffin_manager module.

Changes

Files Change Summary
src/index/Cargo.toml Added dependencies: serde, tantivy with zstd-compression, tantivy-jieba, tokio, and common-test-util.
src/index/src/fulltext_index.rs Introduced Config struct and Analyzer enum to configure fulltext index settings.
src/index/src/fulltext_index/create.rs Added the FulltextIndexCreator trait and methods for text indexing. Exported TantivyFulltextIndexCreator implementation.
src/index/src/fulltext_index/create/tantivy.rs Implemented TantivyFulltextIndexCreator for fulltext indexing with Tantivy, including analyzer configuration and memory management.
src/index/src/fulltext_index/error.rs Introduced structured error handling with the Error enum and Result type alias.
src/index/src/lib.rs Added fulltext_index module.
src/puffin/src/puffin_manager/stager/bounded_stager.rs Corrected the capacity parameter spelling in the new function.
src/puffin/src/puffin_manager/tests.rs Corrected the spelling of capacity variable in function signatures and its usage.

Poem

In the code, where search is found,
New indices now do abound.
With Tantivy's power at our will,
English and Chinese texts we fill.
Serde, Tokio join the stage,
Errors handled, tests engage.
🐇✨ Fulltext searches, fast and sage!


Tip

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 currently opted into early access features by default.

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:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • 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.

Additional comments not posted (6)
src/index/src/lib.rs (1)

17-17: Verify the necessity of the feature flag.

The feature flag iter_partition_in_place is enabled. Ensure it is necessary for the functionality introduced in this module.

src/index/Cargo.toml (1)

27-31: Verify the appropriateness of new dependencies.

Ensure that the versions and features of the new dependencies (serde, tantivy, tantivy-jieba, tokio, and common-test-util) are appropriate for the functionality introduced.

Also applies to: 34-34

src/index/src/fulltext_index.rs (1)

1-37: LGTM! The new module for fulltext indexing is well-defined.

The Config struct and Analyzer enum are correctly implemented with serde for serialization/deserialization and the Default trait.

src/index/src/fulltext_index/create.rs (1)

1-33: LGTM! The FulltextIndexCreator trait and its implementation are well-defined.

The trait and its methods are correctly implemented with appropriate async traits. The module structure is clear and organized.

src/index/src/fulltext_index/create/tantivy.rs (1)

122-315: Comprehensive Unit Tests

The unit tests for TantivyFulltextIndexCreator are comprehensive and cover various configurations and edge cases. This is a good practice to ensure the robustness of the implementation.

src/puffin/src/puffin_manager/stager/bounded_stager.rs (1)

70-70: Typographical Error: "capicity" should be "capacity"

There is a typographical error in the function parameter.

-pub async fn new(base_dir: PathBuf, capicity: u64) -> Result<Self> {
+pub async fn new(base_dir: PathBuf, capacity: u64) -> Result<Self> {

Likely invalid or redundant comment.
