Steps to Reproduce

The core of this issue lies in the discrepancy of data retrieval when using the Find-PSResource cmdlet with different repositories. Specifically, when querying for packages, the Find-PSResource cmdlet is found to be missing data in the Includes property when used against a repository other than PSGallery, such as a Container Registry. This contrasts with the behavior observed when using the PSGallery repository, where the Includes property is populated as expected. To reproduce this issue, follow these steps:

  1. Ensure you have a non-PSGallery repository configured. This could be a Container Registry or any other custom repository configured for PowerShell resource retrieval.
  2. Use the Find-PSResource cmdlet to query for a package from this non-PSGallery repository. For example:
    $a = Find-PSResource -Name az.compute -Repository MAR
    
    In this example, MAR is a placeholder for the name of your non-PSGallery repository.
  3. Examine the Includes property of the returned object. You will observe that the property is empty, meaning it does not contain the expected data about included cmdlets, functions, or other resources.
    $a.Includes
    
  4. Repeat the same steps using the PSGallery repository. You will find that the Includes property is populated correctly.

By following these steps, you can consistently reproduce the issue and confirm the discrepancy in data retrieval between different repositories. This consistent reproduction is crucial for further analysis and resolution of the problem. The key takeaway here is the inconsistent behavior of the Find-PSResource cmdlet depending on the repository being queried, which highlights a potential bug or limitation in the current implementation. This discrepancy can lead to confusion and hinder the effective management of PowerShell resources.

Expected Behavior

The expected behavior of the Find-PSResource cmdlet is that it should consistently retrieve and populate the Includes property, regardless of the repository being queried. The Includes property provides valuable information about the resources contained within a module or package, such as cmdlets, functions, DSC resources, and workflows. This information is crucial for users to understand the capabilities of a module before installing or using it. When querying the PSGallery repository, the expected behavior is observed:

PS> $a = Find-PSResource -Name az.compute -Repository MAR
PS> $a.Includes

Cmdlet         : {Add-AzImageDataDisk, Add-AzVhd, Add-AzVMAdditionalUnattendContent, Add-AzVMDataDisk…}
Command        : {Add-AzImageDataDisk, Add-AzVhd, Add-AzVMAdditionalUnattendContent, Add-AzVMDataDisk…}
DscResource    : {}
Function       : 
RoleCapability : 
Workflow       :

In this example, the Includes property is populated with a list of cmdlets and commands included in the az.compute module. This allows users to quickly see what functions are available within the module. The expectation is that this same level of detail should be available when querying any repository, including Container Registries or other custom repositories. This consistency is essential for a smooth and predictable user experience. The absence of this information can lead to uncertainty and require users to manually inspect modules, which is a time-consuming and inefficient process. Therefore, the consistent population of the Includes property is a fundamental requirement for the Find-PSResource cmdlet to function effectively across all repository types.

Actual Behavior

The actual behavior observed when querying a non-PSGallery repository, such as a Container Registry, deviates significantly from the expected behavior. Instead of populating the Includes property with a list of contained resources, the property is returned as empty. This means that users are unable to see the cmdlets, functions, or other resources included in the module without manually inspecting it. This discrepancy creates a significant usability issue and hinders the discovery and management of PowerShell resources.

PS> $a = Find-PSResource -Name az.compute -Repository MAR
PS> $a.Includes

Cmdlet         : {}
Command        : {}
DscResource    : {}
Function       : {}
RoleCapability : {}
Workflow       : {}

In this example, the Includes property is returned as empty for all resource types, indicating a clear lack of data retrieval from the non-PSGallery repository. This behavior is inconsistent with the PSGallery repository, where the Includes property is populated correctly. This inconsistency raises concerns about the reliability of the Find-PSResource cmdlet when used with non-PSGallery repositories. Users relying on the Includes property for resource discovery may be misled or forced to resort to manual inspection, which is a cumbersome and error-prone process. The implications of this actual behavior are far-reaching, affecting not only individual users but also organizations that rely on PowerShell for automation and management tasks. The inability to accurately determine the contents of a module before installation can lead to security risks, compatibility issues, and overall inefficiency.

Error Details

Currently, there are no specific error messages or exceptions thrown when the Includes property is not populated correctly. This lack of explicit error reporting makes it challenging to diagnose the issue and can lead to confusion for users. The absence of error details means that users may not be aware that the data is missing or that there is a problem with the retrieval process. This silent failure can be particularly problematic as users may unknowingly rely on incomplete information, leading to incorrect decisions or unexpected behavior. The lack of error reporting also makes it more difficult to troubleshoot the issue and identify the root cause. Without specific error messages, developers and administrators are left to rely on manual inspection and trial-and-error, which is a time-consuming and inefficient process. In future iterations of the Microsoft.PowerShell.PSResourceGet module, it would be beneficial to include more detailed error reporting to provide users with actionable information and facilitate the resolution of such issues. Clear error messages or warnings could indicate when the Includes property is not being populated correctly, prompting users to take appropriate steps, such as verifying repository configurations or reporting the issue to the development team.

Environment Data

Understanding the environment in which the issue occurs is crucial for effective troubleshooting and resolution. The following environment data provides valuable context for analyzing the behavior of the Find-PSResource cmdlet:
