OCI Install Strips Prefix on Package

Commencez par ContainerRegistryServerAPICalls, en suivant InstallPackage et InstallVersion jusqu’à GetContainerRegistryRepositoryManifest et au traitement des métadonnées du manifeste. Reproduisez l’installation de GHCR avec un nom préfixé tel que jborean93/publishtest, puis vérifiez que les requêtes de manifeste suivantes conservent le préfixe tandis que l’artefact local utilise le nom du module.

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

When trying to install a package from an OCI registry that contains a prefix, the package prefix is removed when it goes to download the nupkg blob.

Due to https://github.com/PowerShell/PSResourceGet/issues/1946 I've had to add a hack that fixes up the authentication to GHCR. This uses PSNetDetour to patch the token logic. If/when that is ever fixed then this patch isn't needed to replicate this error.

$repoParams = @{
    Name = 'GHCR'
    Uri = 'https://ghcr.io/'
    ApiVersion = 'ContainerRegistry'
}
Register-PSResourceRepository @repoParams

$psGetCmd = Get-Command -Name Install-PSResource -Module Microsoft.PowerShell.PSResourceGet
$psGetType = $psGetCmd.ImplementingType.Assembly.GetType(
    'Microsoft.PowerShell.PSResourceGet.ContainerRegistryServerAPICalls')

$getRegistryTokenMeth = $psGetType.GetMethod(
    'GetContainerRegistryAccessToken',
    [Reflection.BindingFlags]'Instance, NonPublic',
    [type[]]@([bool], [bool], [System.Management.Automation.ErrorRecord].MakeByRefType()))

$sendRequestMeth = $psGetType.GetMethod(
    'GetHttpResponseJObjectUsingDefaultHeaders',
    [Reflection.BindingFlags]'Instance, NonPublic',
    [type[]]@(
        [string],
        [Net.Http.HttpMethod],
        [Collections.ObjectModel.Collection[System.Collections.Generic.KeyValuePair[string, string]]],
        [System.Management.Automation.ErrorRecord].MakeByRefType(),
        [bool]))

Use-NetDetourContext {
    # Fixes logic for getting anonymous token for GHCR
    New-NetDetourHook -Method $getRegistryTokenMeth -Hook {
        param ([bool]$NeedCatalogAccess, [bool]$IsPushOperation, [ref]$ErrorRecord)

        try {
            $registryUri = "https://ghcr.io/v2/"
            $resp = Invoke-WebRequest -Uri $registryUri -SkipHttpErrorCheck
            $bearer = $resp.Headers['WWW-Authenticate'] | Select-Object -First 1
            if (-not $bearer) {
                throw "No WWW-Authenticate found in response headers for '$registryUri'"
            }

            if ($bearer -match 'realm="([^"]+)"') {
                $realm = $matches[1]
            } else {
                throw "Could not extract realm from WWW-Authenticate header '$bearer'"
            }

            if ($bearer -match 'service="([^"]+)"') {
                $service = $matches[1]
            } else {
                throw "Could not extract service from WWW-Authenticate header '$bearer'"
            }

            $tokenUri = "${realm}?service=${service}&client_id=testclient&scope=repository:jborean93/publishtest:pull"
            $tokenResponse = Invoke-WebRequest -Uri $tokenUri -Method Get
            ($tokenResponse.Content | ConvertFrom-Json).token
        }
        catch {
            $_.ErrorDetails = "Failed to retrieve anonymous token: $_"
            $ErrorRecord.Value = $_
        }
    }

    # Prints the URIs requested to show what the problem is
    New-NetDetourHook -Method $sendRequestMeth -Hook {
        param($Url, $Method, $DefaultHeaders, $ErrRecord, $UsePagination)

         [Console]::WriteLine("$Method -> $Url")
        , $Detour.Invoke($Url, $Method, $DefaultHeaders, $ErrRecord, $UsePagination)
    }

    Install-PSResource -Name jborean93/publishtest -Repository GHCR -TrustRepository -Verbose -Debug
}

We can see that

• It is able to find the tags/versions for this package
• It selects the latest version 0.1.2
  • GET -> https://ghcr.io/v2/jborean93/publishtest/tags/list
• It is able to retrieve the OCI manifest through
  • GET -> https://ghcr.io/v2/jborean93/publishtest/manifests/0.1.2
• It derives the module name through that manifest as PublishTest based on the confirmation message
• The step to gettings the manifest after the confirmation fails with a HTTP 400
  • GET -> https://ghcr.io/v2/publishtest/manifests/0.1.2

This step is failing because the URL used no longer contains the package prefix (jborean93) and thus isn't a valid request. The code when calling InstallPackage after it has found the version now uses the module name contained in the manifest which is just PublishTest rather than the original package name provided with the prefix.

The solution to this is to not update the package name from the manifest details and just use the module name on the downloaded artifact locally.
