Transitions

• Stopped -> Starting (start() called)
• Starting -> Initializing (process spawned, DAP initialize sent)
• Starting -> Crashed (spawn failed)
• Initializing -> Configured (initialize response received)
• Initializing -> Crashed (initialize failed or timed out)
• Configured -> Running (launch/attach response received)
• Configured -> Crashed (launch/attach failed)
• Running -> ShuttingDown (disconnect/terminate requested)
• Running -> Crashed (adapter process exited unexpectedly)
• ShuttingDown -> Stopped (adapter exited cleanly)
• Crashed -> Starting (restart attempt)

Variants

Stopped

No debug adapter process is running.

Starting

The debug adapter process is being spawned.

Initializing

The DAP initialize request has been sent and a response is pending.

Configured

The adapter has been initialized and configured, ready for launch/attach.

Running

The debug session is actively running with a live adapter.

ShuttingDown

A disconnect request has been sent and the adapter is shutting down.

Crashed

The adapter process exited unexpectedly or failed to start.
