fix: some streams errors such as pkpatternmatchdel etc #2726

Closed wangshao1 closed 3 months ago

wangshao1 commented 3 months ago
  1. add pkpatternmatchdel unit test.
  2. fix pkpatternmatchdel bug for using wrong key.
  3. fix basemetafilter and datafilter, because stream type doesn't have expire time and uses a different type meta value.

Walkthrough

The changes introduce support for a new kStreams data type within the BaseMetaFilter and BaseDataFilter classes across various files. The updates involve handling stream meta values, adding detailed error logging for stream meta value lengths, and enhancing the functionality to accumulate results in pattern matching deletions.

Changes

Files Change Summaries
src/storage/src/base_filter.h Added support for the kStreams data type in BaseMetaFilter and BaseDataFilter classes. Included parsing and handling for stream meta values.
src/storage/src/pika_stream_meta_value.h Enhanced error logging statements to include the actual and expected lengths of stream meta values.
src/storage/src/redis_strings.cc Reordered assignments within the Redis::PKPatternMatchDel function for improved processing flow.
src/storage/src/storage.cc Updated Storage::PKPatternMatchDel function to accumulate results from multiple instances before returning the final value.

Poem

A new type in the streams of code,
With filters so smart, they decode,
Meta values parsed with care,
Logging errors, now more aware. 🌟
Pattern matching with a touch so neat,
Rabbit's work, impossible to beat. 🐇✨

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 as 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. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration 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.
