Proposed change

Currently the API converts backup locations on network mounts to the Supervisor's Mount representation. However, the locations stored in the backup representations is a dictionary with the location string as key.

Make sure to use the backup location string to validate the remove requests. This fixes removing backups from network storage mounts.

Type of change

  • Dependency upgrade
  • Bugfix (non-breaking change which fixes an issue)
  • New feature (which adds functionality to the supervisor)
  • Breaking change (fix/feature causing existing functionality to break)
  • Code quality improvements to existing code or addition of tests

📝 Walkthrough

Walkthrough

The pull request introduces a minor refactoring in the remove method of the BackupManager class within the supervisor/backups/manager.py file. The change focuses on improving code readability by modifying how location names are filtered and processed. The core logic for removing backup files remains unchanged, with the same error handling and system resolution state management preserved.

Changes

File Change Summary
supervisor/backups/manager.py Refactored location filtering in remove method by introducing an intermediate location_name variable instead of directly calling self._get_location_name(location) in the list comprehension

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.

266-268: Consider handling any unexpected None from _get_location_name.

Although using the walrus operator here is concise and clear, if _get_location_name(location) ever returns None unexpectedly (e.g., a misconfiguration or a removed mount), the list comprehension silently excludes that location without logging. If that is intentional, no change is needed; otherwise, consider logging or raising a warning for unrecognized locations to aid debugging.

 targets = (
     [
-        location_name
-        for location in locations
-        if (location_name := self._get_location_name(location)) in backup.all_locations
+        location_name
+        for location in locations
+        if (location_name := self._get_location_name(location)) is not None
+           and location_name in backup.all_locations
     ]
     if locations
     else list(backup.all_locations.keys())
