Walkthrough

The changes consist of renaming an exported environment variable from SDK_SRCS to SDK_SOURCES across two related shell scripts. In guix-start, the variable export is updated with modified default value logic. In setup-sdk, the variable declaration is replaced and all references throughout the script—including path assignments and directory creation commands—are updated to use the new name consistently.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

The changes follow a homogeneous pattern of variable renaming applied consistently across two shell scripts. There are no new logic flows, structural changes, or complex interactions introduced. Verification involves confirming that all occurrences of the old variable name have been systematically replaced with the new name and that default values are preserved or appropriately adjusted.

Pre-merge checks and finishing touches

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Description Check	❓ Inconclusive	The pull request description consists mostly of an incomplete template with empty sections for "What was done?", "How Has This Been Tested?", and "Breaking Changes", along with an unchecked checklist. While the description includes a reference to a related GitHub issue and uses a structure appropriate for PR documentation, it is extremely vague and generic, providing virtually no meaningful information about the actual changes made, testing performed, or any potential breaking changes. This falls into the category of descriptions that convey little substantive information about the changeset despite being structurally related to the topic.

✅ Passed checks (2 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title "guix: adjust scripts to use SDK_SOURCES env variable properly" directly and clearly summarizes the main change in the pull request. The changeset involves renaming the environment variable from SDK_SRCS to SDK_SOURCES across multiple guix scripts (guix-start and setup-sdk). The title is concise, specific, and uses clear terminology that accurately reflects the primary objective of the changes without vagueness or unnecessary details.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.

12-12: LGTM: variable consistently renamed throughout.

All references to SDK_SRCS have been correctly updated to SDK_SOURCES across the variable declaration (line 12) and its usages in the archive path (line 16) and directory creation (line 21). The logic remains unchanged and aligns with the exported variable from guix-start.

Also applies to: 16-16, 21-21

contrib/containers/guix/scripts/guix-start (1)

14-14: Review comment is based on incorrect assumptions and should be disregarded.

The review claims that old code "incorrectly checked ${SDK_PATH:-...} when setting SDK_SRCS", but verification shows:

• The variable SDK_SRCS does not exist anywhere in the codebase (no references found)
• Line 14 correctly uses ${SDK_SOURCES:-...} and is properly self-referencing its own variable
• Line 13 separately defines SDK_PATH with its own correct self-reference pattern
• SDK_SOURCES has no external dependencies and is only used locally within this file

The code at line 14 is already correct and doesn't need changes. The review's description of the original bug doesn't match the actual codebase.

Likely an incorrect or invalid review comment.
