Walkthrough

The changes in the pkg/installer/template.go file enhance the template update process by adding a mechanism to remove deleted templates from the filesystem. When performing template updates, the code now iterates through a list of deleted template paths and attempts to delete each file. If a deletion fails, a warning message is logged to provide visibility into any removal issues. Additionally, the representation of template changes is improved by updating the summary output to include modified templates and altering the checksum handling logic.

Changes

File Change Summary
pkg/installer/template.go Enhanced updateTemplatesAt to remove deleted templates with error logging; updated String method to include modified templates; changed checksum delimiter from newline to semicolon.

Poem

🐰 A rabbit's tale of templates clean,
Deleted paths, no longer seen,
With os.Remove(), we sweep away,
Stale templates that have lost their day!
Nuclei updates, now sharp and bright! 🔍

🪧 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 <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.

154-159: Consider implementing atomic operations for template updates.

The current implementation could face race conditions during concurrent template operations. Consider implementing atomic operations or using file locks to ensure safe template updates.

Some suggestions:

  1. Use a temporary directory for staging updates
  2. Implement file locking mechanism
  3. Use atomic rename operations for final updates

Would you like me to provide a detailed implementation for these improvements?

154-159: Verify template deletion behavior.

Let's verify the template deletion behavior and its impact on the codebase.

✅ Verification successful

Template deletion behavior is correctly implemented

The current implementation appropriately:

  • Handles individual file deletions with proper error logging
  • Preserves shared directory structures to prevent unintended side effects
  • Uses non-blocking error handling to ensure template updates can continue
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Analyze template deletion patterns and verify cleanup behavior

# Check for potential template file patterns
echo "Analyzing template patterns..."
rg -g '!{.git,node_modules}' -l '(?i)id:\s*[''"][\w-]+[''"]' --type yaml

# Check for empty directories in templates
echo "Checking for empty directories..."
find . -type d -empty -not -path "*/\.*"

# Check for any template references in code
echo "Checking template references..."
rg -l 'template.*\.ya?ml'

Length of output: 1830


Script:

#!/bin/bash
# Check template deletion implementation context
echo "Checking template deletion context..."
rg -B 5 -A 5 "os\.Remove\(.*template.*\)"

# Check for directory cleanup implementations
echo "Checking directory cleanup patterns..."
ast-grep --pattern 'if err := os.Remove($_); $_'

# Check error handling patterns
echo "Checking error handling patterns..."
rg "failed to.*template" -B 2 -A 2
