DebugService is used to initialize a new
DebugSession. This service provides functionality to configure and to start a new debug session. The workflow is the following. If user wants to debug an application and there is no debug configuration associated with the application then the list of available debuggers is requested to create a suitable debug configuration. When configuration is chosen it is possible to alter the configuration by filling in missing values or by adding/changing/removing attributes.
In most cases the default behavior of the
DebugSession is enough. But it is possible to provide its own implementation. The
DebugSessionFactory is used for this purpose via
DebugSessionContribution. Documented model objects are located here
DebugSession life-cycle is controlled and can be tracked as follows:
onDidPreCreateDebugSessionevent indicates that a debug session is going to be created.
onDidCreateDebugSessionevent indicates that a debug session has been created.
onDidDestroyDebugSessionevent indicates that a debug session has terminated.
onDidChangeActiveDebugSessionevent indicates that an active debug session has been changed
ExtDebugProtocol.AggregatedBreakpoint is used to handle breakpoints on the client side. It covers all three breakpoint types:
ExtDebugProtocol.ExceptionBreakpoint. It is possible to identify a breakpoint type with help of
DebugUtils. Notification about added, removed, or changed breakpoints is received via
At the back-end we start a debug adapter using
DebugAdapterFactory and then a
DebugAdapterSession is instantiated which works as a proxy between client and debug adapter. If a default implementation of the debug adapter session does not fit needs, it is possible to provide its own implementation using
DebugAdapterSessionFactory. If so, it is recommended to extend the default implementation of the
DebugAdapterSession. Documented model objects are located here
DebugSessionState accumulates debug adapter events and is used to restore debug session on the client side when page is refreshed.
DebugAdapterContribution is a contribution point for all debug adapters to provide and resolve debug configuration.
Here is an example of debug adapter contribution for node
