Walkthrough

The changes made in this pull request involve a modification to the GetFileContent function in the internal/exec/stack_processor_utils.go file. The function's return behavior has been adjusted to return an empty map instead of a nil value when the stackYamlConfig is an empty string. This ensures that the function explicitly defines its return value for empty content, while the overall structure and logic of the function remain unchanged.

Changes

File Path	Change Summary
internal/exec/stack_processor_utils.go	Modified GetFileContent to return an empty map when stackYamlConfig is an empty string.

Assessment against linked issues

Objective	Addressed	Explanation
Allow empty manifests in JSONSchema (DEV-2362)	❌	The change does not address the need for empty file handling in validation.

Possibly related PRs

• Add support for remote validation schemas #731: This PR introduces changes to the handling of schema manifests, which may indirectly relate to the GetFileContent function's behavior when dealing with configuration files, although it does not modify the same function directly.
• get atmos config and vendor from .yaml or .yml #736: This PR modifies file handling logic in internal/exec/vendor_utils.go, which may relate to how configuration files are processed, similar to the changes in GetFileContent.
• Do not process stack configs when executing command atmos vendor pull and the stack flag is not specified #738: This PR updates the ExecuteVendorPullCommand function, which may involve similar file processing logic as the GetFileContent function, although it does not directly modify it.
• Do not process stack configs when executing command atmos vendor pull and the --stack flag is not specified #740: This PR also modifies the checkAtmosConfig function, which may relate to the overall configuration handling in the same context as the changes made to GetFileContent.

  • I pushed a fix in commit <commit_id>, 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.
