Fix error message during symlink deletion #11331

PR Summary

I hit an issue trying to delete a directory under OneDrive like this:

At C:\Users\roholt\OneDrive - Microsoft\Dev\PowerShellEditorServices\PowerShellEditorServices.build.ps1:126 char:5

C:\Users\roholt\OneDrive - Microsoft\Dev\PowerShellEditorServices [master ≡ +0 ~2 -0 !] [DBG]>> Remove-Item "$root/module/PowerShellEditorServices/bin" -Recurse -Force -Verbose
Remove-Item: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Expanding the error revealed this:

I've tried writing tests that look like this:

    Describe -Name "Symbolic links" -Tag "RequireAdminOnWindows" {
        BeforeEach {
            $testDir = New-Item -Path $TestDrive -Name "testdir" -ItemType Directory
        }

        AfterEach {
            if (Test-Path $testDir)
            {
                Remove-Item $testDir -Force -Recurse
            }
        }

        It "Should be able to delete a symlink to the directory" {
            $subDir = New-Item -ItemType Directory -Path $testDir -Name "subdir"
            New-Item -ItemType File -Path $subDir -Name "txt" -Value "nothing to see here"
            $symlink = New-Item -Name "kwyjibo" -Path $TestDrive -ItemType SymbolicLink -Target $testDir

            Remove-Item $symlink -Recurse -Force

            Test-Path $testDir | Should -BeTrue
            Get-ChildItem $testDir | Should -HaveCount 0
        }

        It "Should fail properly when a symlink cannot be deleted" {
            $subDir = New-Item -ItemType Directory -Path $testDir -Name "subdir"
            New-Item -ItemType File -Path $subDir -Name "txt" -Value "nothing to see here" -Force
            $file = New-Item -ItemType File -Path $subDir -Name "txt" -Value "nothing to see here"
            $symlink = New-Item -Name "kwyjibo" -Path $TestDrive -ItemType SymbolicLink -Target $testDir

            $file = [System.IO.File]::Open($file, 'open', 'read', 'none')
            try
            {
                Remove-Item $symlink -Recurse -Force

                Test-Path $testDir | Should -BeTrue
                Get-ChildItem $testDir | Should -HaveCount 0
            }
            finally
            {
                $file.Close()
                $file.Dispose()
            }
        }
    }

However, they don't fail like OneDrive symlinks do and I'm not sure how to emulate this behaviour.

This is a very simple fix though: the recurse parameter needed to be passed to Delete() and the error message needed its second argument passed through.

PR Checklist

iSazonov · 2019-12-13T07:21:00Z

I do not review in depth but I have concerns because there is old history:
#621
#3637
#3674

anmenaga · 2020-01-24T21:09:50Z

after looking at those linked items, I agree with @iSazonov . We need more info before we can safely merge this. Specifically:

what happens before and after this change when target directory is not empty; this change is adding recurse=true argument to DirectoryInfo.Delete(Boolean) and looking at linked items that may end as a breaking change.
what is so special about OneDrive symlinks
maybe we can separate fixing the error message into a separate PR; as far as I understand that does not depend on DirectoryInfo.Delete(Boolean) modification?

I'm happy with that.

what is so special about OneDrive symlinks

Well the answer to that seems to be "they require recurse set to delete". But I would like to know the full answer as well.

rjmholt · 2020-01-27T17:50:26Z

But agreed. I think the bottom line is that if different symlinks behave differently, we need a way to differentiate them and get the right behaviour for each and this PR doesn't do that. I'll reduce it back to the error message fix.

+                    // TODO:
+                    // Different symlinks seem to vary by behavior.
+                    // In particular, OneDrive symlinks won't remove without recurse,
+                    // but the .NET API here does not allow us to distinguish them.
+                    // We may need to revisit using p/Invokes here to get the right behavior


Should we remove the comment too?

I just put it in in the last commit, since the current behaviour won't work for OneDrive symlinks (why I opened the PR).

Maybe it is better to open a tracking issue?

How about both? Comments like this often help me when I find them in the code, because I usually hit them when I'm trying to fix something that I didn't realise was related.
