Add Reset-PSResourceRepository cmdlet to recover from corrupted repository store #1895

Copilot · 2025-10-08T20:05:41Z

Summary

Implemented Reset-PSResourceRepository cmdlet that resets the repository store to default state with only PSGallery registered.

Key Features:

Safety-first approach: creates new file in temp location, validates, then replaces old file
Backup and restore mechanism if creation fails
ShouldProcess support with ConfirmImpact=High
PassThru parameter to return PSGallery repository info
Updated error messages to suggest using Reset-PSResourceRepository when store is corrupted

Latest Update:

Added error handling for temporary file cleanup when validation fails
Reports both validation error and cleanup error if cleanup also fails

Verification:

✓ Cmdlet compiles successfully
✓ Reset method added to RepositorySettings
✓ ShouldProcess enabled with High confirm impact
✓ PassThru parameter implemented
✓ Test file created with 6 test cases
✓ Error message updated in CheckRepositoryStore
✓ Cmdlet added to module manifest exports
✓ File operations use Utils.MoveFiles for consistency
✓ All cleanup errors are properly reported
✓ Validation errors are properly handled

Original prompt

This section details on the original issue you should resolve

<issue_title>Repository store (PSRepositories.xml) should have 'reset' functionality</issue_title>
<issue_description>### Prerequisites

Write a descriptive title.

Make sure you are able to repro it on the latest released version

Search the existing issues.

Steps to reproduce

If the repository store gets corrupted, PSGet throws an error from attempting to parse the file. At the very least, error messaging should provide user with steps to remedy the situation. We should, however, also add either a new parameter or a new cmdlet that allows users to delete the old PSRepositories.xml file and create a new default file.

I'm proposing:
Register-PSResourceRepository -Reset
which, again, would delete the current PSRepositories.xml file, create a new one, and then register only the PowerShellGallery.

Expected behavior
If the xml file is unable to be parsed, an error throws telling the user that there was a parse error and suggesting to either try rerunning the command or running Register-PSResourceRepository -Reset to reset the repository store.
Actual behavior
Throws parse error and fails.

<agent_instructions>create a new cmdlet 'Reset-PSResourceRepository' that will create a new PSRepository.xml file. However, make sure that a new file is created first and once that new file is successfully created the old one is deleted. If the new file cannot be created, restore the old file. </agent_instructions>

@StevenBucher98 Adding some ShouldProcess logic in order to make sure the user understands what is happening and where the file is that they are going to reset @alerickson @mgreenegit consider documentation on how to handle a 'reset' scenario

@copilot in 'Reset(PSCmdlet cmdletPassedIn, out string errorMsg)', instead of copying files, just move them

@copilot in 'Reset(PSCmdlet cmdletPassedIn, out string errorMsg)', instead of copying files, just move them

Updated the Reset method to use Utils.MoveFiles() instead of File.Copy() for all file operations in commit a2c0ca2. This provides better cross-volume compatibility and simplifies the code.
