Eigenverft.Manifested.Sandbox.PackageModel.Upstream.GitHubRelease #> function Get-GitHubRelease { <# .SYNOPSIS Gets one fixed GitHub release by tag through the GitHub Releases API. .DESCRIPTION Calls the GitHub REST API through Invoke-WebRequestEx, parses the release metadata JSON, and returns a normalized release object with normalized asset metadata. This helper is intentionally focused on fixed release lookup by tag for PackageModel upstream resolution and does not implement "latest" behavior. .PARAMETER RepositoryOwner The GitHub repository owner or organization name. .PARAMETER RepositoryName The GitHub repository name. .PARAMETER ReleaseTag The GitHub release tag name to resolve. .EXAMPLE Get-GitHubRelease -RepositoryOwner ggml-org -RepositoryName llama.cpp -ReleaseTag b8863 #> [CmdletBinding()] param( [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [string]$RepositoryOwner, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [string]$RepositoryName, [Parameter(Mandatory = $true)] [ValidateNotNullOrEmpty()] [string]$ReleaseTag ) $headers = @{ 'User-Agent' = 'Eigenverft.Manifested.Sandbox' 'Accept' = 'application/vnd.github+json' 'X-GitHub-Api-Version' = '2022-11-28' } $encodedTag = [System.Uri]::EscapeDataString($ReleaseTag) $uri = 'https://api.github.com/repos/{0}/{1}/releases/tags/{2}' -f $RepositoryOwner, $RepositoryName, $encodedTag try { $response = Invoke-WebRequestEx -Uri $uri -Headers $headers -UseBasicParsing -ErrorAction Stop } catch { throw "Get-GitHubRelease failed for repository '$RepositoryOwner/$RepositoryName' and release tag '$ReleaseTag'. $($_.Exception.Message)" } try { $release = $response.Content | ConvertFrom-Json -ErrorAction Stop } catch { throw "Get-GitHubRelease received invalid JSON for repository '$RepositoryOwner/$RepositoryName' and release tag '$ReleaseTag'. $($_.Exception.Message)" } $assets = @( foreach ($asset in @($release.assets)) { $sha256 = $null if ($asset.PSObject.Properties['digest'] -and -not [string]::IsNullOrWhiteSpace([string]$asset.digest)) { $digestMatch = [regex]::Match([string]$asset.digest, '^sha256:(?<value>[0-9a-fA-F]{64})$') if ($digestMatch.Success) { $sha256 = $digestMatch.Groups['value'].Value.ToLowerInvariant() } } [pscustomobject]@{ Id = if ($asset.PSObject.Properties['id']) { [string]$asset.id } else { $null } Name = if ($asset.PSObject.Properties['name']) { [string]$asset.name } else { $null } DownloadUrl = if ($asset.PSObject.Properties['browser_download_url']) { [string]$asset.browser_download_url } else { $null } ContentType = if ($asset.PSObject.Properties['content_type']) { [string]$asset.content_type } else { $null } Size = if ($asset.PSObject.Properties['size']) { [int64]$asset.size } else { 0L } Digest = if ($asset.PSObject.Properties['digest']) { [string]$asset.digest } else { $null } Sha256 = $sha256 CreatedAtUtc = if ($asset.PSObject.Properties['created_at']) { [string]$asset.created_at } else { $null } UpdatedAtUtc = if ($asset.PSObject.Properties['updated_at']) { [string]$asset.updated_at } else { $null } } } ) return [pscustomobject]@{ RepositoryOwner = $RepositoryOwner RepositoryName = $RepositoryName ReleaseId = if ($release.PSObject.Properties['id']) { [string]$release.id } else { $null } ReleaseTag = if ($release.PSObject.Properties['tag_name']) { [string]$release.tag_name } else { $ReleaseTag } ReleaseName = if ($release.PSObject.Properties['name']) { [string]$release.name } else { $null } HtmlUrl = if ($release.PSObject.Properties['html_url']) { [string]$release.html_url } else { $null } PublishedAtUtc = if ($release.PSObject.Properties['published_at']) { [string]$release.published_at } else { $null } Draft = if ($release.PSObject.Properties['draft']) { [bool]$release.draft } else { $false } Prerelease = if ($release.PSObject.Properties['prerelease']) { [bool]$release.prerelease } else { $false } Immutable = if ($release.PSObject.Properties['immutable']) { [bool]$release.immutable } else { $false } Assets = @($assets) } } |
