Feature: Robust service provider loading #27

Closed infeo closed 9 months ago

infeo commented 9 months ago

Closes #26.

This PR improves discovery and loading of supported service providers by catching common exceptions/errors during this process (ExceptionInInitializationError, NoClassDefFoundError, RuntimeException).

If one of those throwables are thrown, the service provider is considered as "not supported" and filtered out.

Walkthrough

The changes focus on enhancing the resilience of the IntegrationsLoader in handling service loading failures. By refining the loading process, the updates ensure that an exception thrown by one service does not prevent the loading of others. This includes the introduction of a method for more robust service provider instantiation, improved error logging, and specific test cases to verify the behavior when exceptions are encountered.

Changes

File Path Change Summary
.../common/IntegrationsLoader.java Added ServiceConfigurationError handling, new instantiateServiceProvider method, and improved error logging.
.../common/IntegrationsLoaderTest.java Added tests for handling exceptions in @CheckAvailability methods.
.../common/InitExceptionTestClass.java New file for testing initialization exceptions.

Poem

In the code where services dwell, A rabbit worked, casting its spell. With a hop and a leap, no error too steep, It weaved resilience, so deep.

"Fear not," it squeaked, with a twinkle in eye, "For your services, no longer will sigh. Through storms and errors, they'll stand tall, United we code, we'll never fall."

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 .` - `Generate unit-tests for this file.` - 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 tests 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 from git and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit tests.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` 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 a review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@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. - The JSON schema for the configuration file is available [here](https://coderabbit.ai/integrations/coderabbit-overrides.v2.json). - 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/coderabbit-overrides.v2.json` ### CodeRabbit Discord Community Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback.
