bug_fix, enhancement
Description
Enhanced the logic for parsing the AWS region from EKS cluster names, supporting a wider range of cluster name formats.
Improved error handling in cases where the region cannot be determined from the cluster name.
Added comprehensive test cases to validate the parsing of AWS regions from various EKS cluster name formats, including handling of environment variables.

ekssupport.go
Enhanced EKS Region Parsing Logic
cloudsupport/v1/ekssupport.go
Improved logic for extracting region from EKS cluster name.
Added support for cluster names with different formats.
Enhanced error handling for cases where the region cannot be determined.
2, because the changes are localized to a specific functionality (EKS region parsing) and include both implementation and tests. The logic is straightforward, and the tests are comprehensive.
🧪 Relevant tests
Yes
🔍 Possible issues
The condition len(splittedClusterContext) >= 6 in ekssupport.go might be too restrictive for future or custom EKS cluster naming conventions. Consider if there's a more flexible way to determine the region without hardcoding the expected number of segments.
The test case "Region is extracted from cluster name with ':' separator" expects an error (expectErr: true), but the description suggests it's testing successful region extraction. This might be a misunderstanding or a copy-paste error in the test case description.

✨ Review tool usage guide:
Overview:
The review tool scans the PR code changes, and generates a PR review. The tool can be triggered automatically every time a new PR is opened, or can be invoked manually by commenting on any PR.
When commenting, to edit configurations related to the review tool (pr_reviewer section), use the following template:
The review tool can be configured with extra instructions, which can be used to guide the model to a feedback tailored to the needs of your project.
Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Specify the relevant sub-tool, and the relevant aspects of the PR that you want to emphasize.
Examples for extra instructions:
[pr_reviewer] # /review #
extra_instructions="""
In the 'possible issues' section, emphasize the following:
- Does the code logic cover relevant edge cases?
- Is the code logic clear and easy to understand?
- Is the code logic efficient?
...
"""
Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable.
How to enable\disable automation
When you first install PR-Agent app, the default mode for the review tool is:
pr_commands = ["/review", ...]
meaning the review tool will run automatically on every PR, with the default configuration.
Edit this field to enable/disable the tool, or to change the used configurations
Auto-labels
The review tool can auto-generate two specific types of labels for a PR:
a possible security issue label, that detects possible security issues (enable_review_labels_security flag)
a Review effort [1-5]: x label, where x is the estimated effort to review the PR (enable_review_labels_effort flag)
Extra sub-tools
The review tool provides a collection of possible feedbacks about a PR.
It is recommended to review the possible options, and choose the ones relevant for your use case.
Some of the feature that are disabled by default are quite useful, and should be considered for enabling. For example: require_score_review, require_soc2_ticket, and more.
Auto-approve PRs
By invoking:
/review auto_approve
The tool will automatically approve the PR, and add a comment with the approval.
To ensure safety, the auto-approval feature is disabled by default. To enable auto-approval, you need to actively set in a pre-defined configuration file the following:
[pr_reviewer]
enable_auto_approval = true
(this specific flag cannot be set with a command line argument, only in the configuration file, committed to the repository)
You can also enable auto-approval only if the PR meets certain requirements, such as that the estimated_review_effort is equal or below a certain threshold, by adjusting the flag:
[pr_reviewer]
maximal_review_effort = 5
More PR-Agent commands
To invoke the PR-Agent, add a comment using one of the following commands:
/review: Request a review of your Pull Request.
/describe: Update the PR title and description based on the contents of the PR.
Simplify conditional logic by removing unnecessary else keywords.
Consider simplifying the conditional logic by removing the else keyword since the if block ends with a return statement. This will enhance readability and maintainability.
Replace magic numbers with named constants for clarity and maintainability.
To ensure consistency and avoid magic numbers, consider defining a constant for the magic number 6 used in the condition check. This will make the code more readable and easier to maintain.
Ensure environment variables are cleaned up in tests by deferring their unset at the start.
It is a good practice to clean up environment variables in tests by deferring their unset at the beginning of the test function. This ensures that even if the test fails or panics, the environment variable will be cleaned up, maintaining test isolation.
Correct the expected error flag for a test case to match its description.
For the test case where the region is expected to be extracted from the cluster name with a ':' separator, the expectErr field is set to true. This seems to be a mistake since the test case description and expected behavior suggest that the region extraction should succeed. Consider setting expectErr to false.
{
name: "Region is extracted from cluster name with ':' separator",
cluster: "cluster:us-west-2:eks",
expectedRegion: "us-west-2",
- expectErr: true,+ expectErr: false,
}
enhancement
Add a test case for unexpected cluster name formats to verify error handling.
To improve the robustness of your tests, consider adding a case to explicitly test the behavior when the cluster name does not follow the expected format. This will help ensure that your error handling works as expected.
{
- name: "Failed to get region",- cluster: "cluster",+ name: "Failed to get region due to unexpected format",+ cluster: "unexpected-format-cluster",
expectErr: true,
}
✨ Improve tool usage guide:
Overview:
The improve tool scans the PR code changes, and automatically generates suggestions for improving the PR code. The tool can be triggered automatically every time a new PR is opened, or can be invoked manually by commenting on a PR.
When commenting, to edit configurations related to the improve tool (pr_code_suggestions section), use the following template:
meaning the improve tool will run automatically on every PR, with summarization enabled. Delete this line to disable the tool from running automatically.
Utilizing extra instructions
Extra instructions are very important for the improve tool, since they enable to guide the model to suggestions that are more relevant to the specific needs of the project.
Be specific, clear, and concise in the instructions. With extra instructions, you are the prompter. Specify relevant aspects that you want the model to focus on.
Examples for extra instructions:
[pr_code_suggestions] # /improve #
extra_instructions="""
Emphasize the following aspects:
- Does the code logic cover relevant edge cases?
- Is the code logic clear and easy to understand?
- Is the code logic efficient?
...
"""
Use triple quotes to write multi-line instructions. Use bullet points to make the instructions more readable.
A note on code suggestions quality
While the current AI for code is getting better and better (GPT-4), it's not flawless. Not all the suggestions will be perfect, and a user should not accept all of them automatically.
Suggestions are not meant to be simplistic. Instead, they aim to give deep feedback and raise questions, ideas and thoughts to the user, who can then use his judgment, experience, and understanding of the code base.
Recommended to use the 'extra_instructions' field to guide the model to suggestions that are more relevant to the specific needs of the project, or use the custom suggestions 💎 tool
With large PRs, best quality will be obtained by using 'improve --extended' mode.
More PR-Agent commands
To invoke the PR-Agent, add a comment using one of the following commands:
/review: Request a review of your Pull Request.
/describe: Update the PR title and description based on the contents of the PR.
Add this suggestion to a batch that can be applied as a single commit.This suggestion is invalid because no changes were made to the code.Suggestions cannot be applied while the pull request is closed.Suggestions cannot be applied while viewing a subset of changes.Only one suggestion per line can be applied in a batch.Add this suggestion to a batch that can be applied as a single commit.Applying suggestions on deleted lines is not supported.You must change the existing code in this line in order to create a valid suggestion.Outdated suggestions cannot be applied.This suggestion has been applied or marked resolved.Suggestions cannot be applied from pending reviews.Suggestions cannot be applied on multi-line comments.Suggestions cannot be applied while the pull request is queued to merge.Suggestion cannot be applied right now.
