This function is useful for determining whether it's safe to shut down ComfyUI without interrupting ongoing processing. .EXAMPLE Test-ComfyUIQueueEmpty Returns $true if the queue is empty, $false if there are pending tasks. .EXAMPLE if (Test-ComfyUIQueueEmpty) { Stop-ComfyUI } Conditionally shuts down ComfyUI only if no tasks are queued. .NOTES This function requires an active ComfyUI server connection and uses the $script:comfyUIApiUrl variable to determine the API endpoint. If the queue endpoint is not accessible, the function assumes the queue is empty to avoid blocking shutdown. #> function Test-ComfyUIQueueEmpty { [CmdletBinding()] param() begin { GenXdev.AI\EnsureComfyUI # construct queue api endpoint url $queueUrl = "${script:comfyUIApiUrl}/queue" } process { try { # query the queue endpoint to get current status $queueResponse = Microsoft.PowerShell.Utility\Invoke-RestMethod ` -Verbose:$false ` -ProgressAction Continue ` -Uri $queueUrl ` -Method GET ` -TimeoutSec 3 # analyze queue response structure $queueEmpty = $true # check for pending tasks in queue_pending if ($queueResponse.queue_pending -and ($queueResponse.queue_pending.Count -gt 0)) { Microsoft.PowerShell.Utility\Write-Verbose ` "Found $($queueResponse.queue_pending.Count) pending tasks in queue" $queueEmpty = $false } # check for running tasks in queue_running if ($queueResponse.queue_running -and ($queueResponse.queue_running.Count -gt 0)) { Microsoft.PowerShell.Utility\Write-Verbose ` "Found $($queueResponse.queue_running.Count) running tasks in queue" $queueEmpty = $false } # verbose output for debugging if ($queueEmpty) { Microsoft.PowerShell.Utility\Write-Verbose "ComfyUI queue is empty" } else { Microsoft.PowerShell.Utility\Write-Verbose "ComfyUI queue has active tasks" } return $queueEmpty } catch { # if queue endpoint is not accessible, assume it's safe to shutdown Microsoft.PowerShell.Utility\Write-Verbose ` "Could not access ComfyUI queue endpoint: $($_.Exception.Message)" Microsoft.PowerShell.Utility\Write-Verbose ` "Assuming queue is empty for shutdown purposes" return $true } } end { } } ############################################################################### |
