This function is used to clean up ComfyUI processes after image generation or when a forced shutdown is requested. It provides verbose feedback for debugging and handles cases where no ComfyUI processes are running. .EXAMPLE Stop-ComfyUI -Verbose Terminates ComfyUI processes with detailed output for debugging. .NOTES This function is designed to be called by other ComfyUI-related cmdlets, such as Invoke-ComfyUIImageGeneration, particularly when the -Force parameter is used or when -KeepComfyUIRunning is not specified. It uses PowerShell's process management to ensure clean termination without leaving orphaned processes. #> function Stop-ComfyUI { [CmdletBinding()] [System.Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseShouldProcessForStateChangingFunctions', '')] param() begin { # display progress indicator to inform user of operation status Microsoft.PowerShell.Utility\Write-Progress ` -Activity "ComfyUI Termination" ` -Status "Stopping ComfyUI processes..." } process { try { # search for all running processes with the name 'comfyui' $comfyProcesses = Microsoft.PowerShell.Management\Get-Process ` -Name 'comfyui' ` -ErrorAction SilentlyContinue # evaluate if any comfyui processes were discovered if ($comfyProcesses) { # inform user about the number of processes found Microsoft.PowerShell.Utility\Write-Verbose ( "Found $($comfyProcesses.Count) ComfyUI process(es) to " + "terminate." ) # iterate through each discovered process for termination foreach ($process in $comfyProcesses) { # inform user about the specific process being terminated Microsoft.PowerShell.Utility\Write-Verbose ( "Terminating process ID $($process.Id)..." ) # forcefully terminate the process to ensure cleanup Microsoft.PowerShell.Management\Stop-Process ` -Id $process.Id ` -Force ` -ErrorAction Stop } # pause briefly to allow system to complete process termination Microsoft.PowerShell.Utility\Start-Sleep -Milliseconds 500 # check if any comfyui processes are still running after termination $remainingProcesses = Microsoft.PowerShell.Management\Get-Process ` -Name 'comfyui' ` -ErrorAction SilentlyContinue # verify successful termination of all processes if (-not $remainingProcesses) { # confirm successful termination to user Microsoft.PowerShell.Utility\Write-Verbose ( "All ComfyUI processes successfully terminated." ) } else { # warn user about processes that could not be terminated Microsoft.PowerShell.Utility\Write-Warning ( "Some ComfyUI processes could not be terminated." ) } } else { # inform user that no comfyui processes were found Microsoft.PowerShell.Utility\Write-Verbose ( "No ComfyUI processes found running." ) } } catch { # handle and report any errors during process termination Microsoft.PowerShell.Utility\Write-Warning ( "Failed to stop ComfyUI processes: $($_.Exception.Message)" ) } } end { # complete the progress indicator to signal operation completion Microsoft.PowerShell.Utility\Write-Progress ` -Activity "ComfyUI Termination" ` -Completed } } ################################################################################ |
