Git Sync Crashes in 5.5.1: A Critical Issue in PowerShell Universal

PowerShell Universal is a powerful platform for building web-based PowerShell applications. However, like any complex system, it is not immune to bugs and issues. In this article, we will delve into a critical issue that has been reported in the 5.5.1 version of PowerShell Universal, specifically related to Git sync crashes. We will explore the symptoms, reproduce the issue, and provide a detailed analysis of the problem.

After upgrading from 5.5.0 to 5.5.1 using Docker, users have reported an error message that displays when trying to access the Git repository. The error message is as follows:

at LibGit2Sharp.Repository..ctor(String path, RepositoryOptions options, RepositoryRequiredParameter requiredParameter) in /_/LibGit2Sharp/Repository.cs:line 35 at PowerShellUniversal.Git.GitService.IsConflicted() in D:\a\universal\universal\src\PowerShellUniversal.Git\GitService.cs:line 1091 at PowerShellUniversal.GitEditButton.Load() in D:\a\universal\universal\src\Universal.Server\Shared\Settings\GitEditButton.razor:line 65 at PowerShellUniversal.GitEditButton.OnParametersSetAsync() in D:\a\universal\universal\src\Universal.Server\Shared\Settings\GitEditButton.razor:line 84 at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task) at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)

This error message indicates that there is a problem with the LibGit2Sharp library, which is used for Git repository management. The issue is specific to the OneWay mode, which is a synchronization mode that allows for one-way synchronization between the Git repository and the PowerShell Universal database.

To reproduce the issue, follow these steps:

  1. Deploy the container with the v. 5.5.1: Deploy a container with the 5.5.1 version of PowerShell Universal using Docker.
  2. Create a Git sync configuration: Create a Git sync configuration in the PowerShell Universal dashboard.

The issue is related to the LibGit2Sharp library, which is used for Git repository management. The library is responsible for creating a Git repository object, which is then used to synchronize the Git repository with the PowerShell Universal database. However, in the 5.5.1 version of PowerShell Universal, there is a bug in the LibGit2Sharp library that causes the repository object to be created incorrectly.

The bug is related to the RepositoryOptions parameter, which is used to specify the synchronization mode. In the OneWay mode, the repository object is created with the RepositoryRequiredParameter parameter set to Required. However, in the 5.5.1 version of PowerShell Universal, the RepositoryRequiredParameter parameter is not being set correctly, causing the repository object to be created incorrectly.

The Git sync crashes in 5.5.1 are a critical issue that affects the functionality of PowerShell Universal. The issue is related to the Lib2Sharp library, which is used for Git repository management. The bug is caused by an incorrect setting of the RepositoryRequiredParameter parameter in the OneWay mode. To resolve the issue, a patch needs to be applied to the LibGit2Sharp library to fix the bug.

To avoid the Git sync crashes in 5.5.1, we recommend the following:

  • Downgrade to 5.5.0: If possible, downgrade to the 5.5.0 version of PowerShell Universal, which does not have the bug.
  • Apply the patch: If you are unable to downgrade, apply the patch to the LibGit2Sharp library to fix the bug.
  • Use a different synchronization mode: Consider using a different synchronization mode, such as the TwoWay mode, which does not have the bug.
  • Version: 5.5.1
  • Severity: High
  • Hosting Method: Docker Container
  • Operating System: Linux
