Process

The process dialog displays information about the processes within Lisp. See multiprocessing.htm for information on processes. It is displayed with the View | Processes menu item.

Click on the Update button to update the display. It is not updated automatically.

The Headings

• Name: The name of the process
• Brk: The break level of the process. A process enters a higher break level when an error is signaled but not handled. Other conditions, when signaled, may put a process in a break level under certain circumstances (when *break-on-signals* is true, e.g.) Break level 0 means no unhandled error or condition.
• State: The state of the process (active, runnable, waiting, etc.)
• Status Note: The "whostate" of the process (as returned by process-whostate). While the value can be any string, it usually describes what the process is doing.
• Prio: The priority of the process.
• Quantum (Q... in the illustration): The process quantum.
• Time: the (approximate) total cpu time consumed by the process.
• Delta: The cpu time consumed since the last report.
• Dis: The number of times the process has been resumed since the last report.
• Analyzable (A... in the illustration) A * in the column indicates the process can be included in a runtime analysis (see runtime-analyzer.htm.
• Arrest Reasons the arrest reasons (as returned by process-arrest-reasons) of the process.

The buttons

• Update: update the display.
• Debug: display the process stack backtrace in the debug window.
• Arrest: Arrest the process for arrest reason "debugging".
• Unarrest: Remove (if possible) the arrest reasons of the process.
• Abort: Unwind the process thread clearing all errors and break levels.
• Delete: Kill (and delete) the process.
