// ActivDbg.idl : ActiveX Debugging Interfaces
/* Overview
Active Debugging is a set of interfaces that allow language-neutral, host-neutral debugging,
with support for a wide variety of development environments.

<INSERT SRC="..\..\doc\figures.doc!Architecture">

By <I> language neutral </I>, we mean that a debugging environment can support essentially any
programming language, without having to have specific knowledge of that language
built into the environment.  (Today, the interfaces focus primarily on support
scripting  languages such as VBScript and JScript, as well as Java, but in the
future we intended  evolve them to support native code in languages such as C++.)
Furthermore, the debugger automatically has the ability to debug applications
written in a mixture of  multiple languages, with cross-language stepping and
breakpoints.

By <I> host neutral </I>, we mean that the debugger can be automatically be used with any Active
Scripting host, such as Internet Explorer, Spruuids,  or any any other host written in
the future.  We also mean that the host has control over the structure of the document
tree presented to the user and the contents and syntax coloring of the documents being
debugged.   This allows the host to present the source code being debugged in the context
 of the host document (for example, scripts can be show on an HTML page.)
In the subsections below, we consider each of the key components in Active Debugging and
their associated interfaces.

Before proceeding further, we should define several key Active Debugging concepts:

<I> host application: </I> The application that hosts the script engines and provides
a scriptable set of objects (or "object model").

<I> language engine: </I>  A component that provides parsing, execution, and debugging
abstractions for a particular languages.

<I> debugger IDE: </I>  The application that provides debugging UI by communicating with
the host application and language engines.

<I> machine debug manager: </I> A component that maintains a registry of debuggable
application processes.

<I> process debug manager: </I> A component that maintains the tree of debuggable documents
a particular application, tracks the running threads, etc.

<I> document context: </I> :  A document context is an abstraction representing
a specific range in the source code of a host document.

<I> code context: </I> A code context represents a particular location in the running
code of a language engine (a "virtual instruction pointer".)

<I> expression context: </I>  A particular context (for example, a stack frame) in which
expressions may be evaluated by a language engine.

<I> object browsing: </I>  A structured, language-independent representation of an objects
name, type, value, and subobjects, suitable for implementating a "watch window" UI.

Below, we provide an overview of each of the key Active Debugging components
and their associated interfaces, followed by the details of those interfaces.

/* <H2> Language Engine  </H2>
The language engine provides:

- Language parsing and execution
- Debugging support (breakpoints,etc..).
- Expression evaluation.
- Syntax coloring.
- Object browsing.
- Stack enumeration and parsing.

Below is a list of the key interfaces implemented by a language engine.  These interfaces
are used by the host application to map between its document context and the engine's
code contexts, and also by the debugger UI to do expression evaluation, stack enumeration,
and object browsing.

*/
interface IActiveScriptDebug32;			// provides syntax coloring and code context enumeration (32bit PDM)
interface IActiveScriptDebug64;			// provides syntax coloring and code context enumeration (64bit PDM)
interface IActiveScriptErrorDebug;		// returns document contexts and stack frames for errors
interface IActiveScriptSiteDebug32;		// host provided link from script engine to debugger (32bit PDM)
interface IActiveScriptSiteDebug64;		// host provided link from script engine to debugger (64bit PDM)
interface IActiveScriptTextInfo;

// Language engine debugging abstractions
interface IDebugCodeContext;			// a virtual "instruction pointer" in a thread
interface IEnumDebugCodeContexts;
interface IDebugStackFrame;				// logical stack frame on the stack of a thread
interface IDebugExpressionContext;		// a context in which expressions can be evaluated.
interface IDebugStackFrameSniffer;		// enumerator for stack frames known by an engine

// Asynchronous Expression Evaluation
interface IDebugExpressionContext;		// context for expression evaluation
interface IDebugExpression;			// an asynchronously evaluated expression
interface IDebugSyncOperation;			
interface IDebugAsyncOperation;
interface IDebugAsyncOperationCallBack;
interface IDebugExpressionCallBack;		// status events for IDebugExpression evaluation progress

interface IEnumDebugExpressionContexts;
interface IProvideExpressionContexts;

// Object browsing
interface IDebugFormatter;

/* <H2> Hosts </H2>
The host:
- Hosts the language engines.
- Provides an object model (set of objects that can be scripted)
- defines a tree of documents that can be debugged and their contents
- Organizes scripts into virtual applications.

There are two kinds of hosts:
1.	A dumb host supports just the basic ActiveScripting interfaces.
It has no control over document structure or organizations; this is determined
entirely by the scripts provided to the language engines.

2.	A smart host supports a larger set of interface that allow it to define
the document tree, document contents, and syntax coloring.  There are a set of
helper interfaces, described in the next subsection, which make it much easier for
a host to be a smart host.

<H3> Smart host Helper Interfaces  </H3>
The IDebugDocumentHelper are a greatly simplified set of interfaces that a host
can use to gain the benefits of smart-hosting without having to handle the full
complexity (and power) of the full host interfaces.

A host is not required to use these interfaces, of course, but by using these
can avoid having to implement or use a number of more complicated interfaces.*/

interface IDebugDocumentHelper32;  // implemented by PDM (32-bit)
interface IDebugDocumentHelper64;  // implemented by PDM (64-bit)
interface IDebugDocumentHost;    // implemented (optionally) by the host

/* <H3> Full smart-host interfaces. </H3>

Below is the full set of interfaces that a smart-host needs to implement or use if
it's not using the helper interfaces.

*/

// implemented by host
interface IDebugDocumentInfo;		// provides info on (possibily uninstantiated) doc
interface IDebugDocumentProvider;   // allows doc to be instantiated on demand
interface IDebugDocument;			// base document interface
interface IDebugDocumentText;		// provides access to source text of document
interface IDebugDocumentTextEvents; // events fired when source text changes
interface IDebugDocumentTextAuthor;
interface IDebugDocumentContext;	// represents a range within the document

// implemented by PDM on behalf of the host
interface IDebugApplicationNode;		  // represents the position of a doc in the hierarchy
interface IDebugApplicationNodeEvents;    // events fired by PDM when document hierarchy changes


/* <H2> Debugger IDE </H2>
The IDE is a fully language independent debugging UI.  It provides:

- Document viewers/editors.
- Breakpoint management.
- Expression evaluation and watch windows.
- Stack frame browsing.
- Object/Class browsing.
- Browsing the virtual application structure.

*/
// Debugger implementation
interface IDebugSessionProvider;     // establishes a debug session for a running application.
interface IApplicationDebugger;      // primary interface exposed by a debugger IDE session


/* <H2> Machine Debug Manager </H2>
The machine debug manager provides the hookup point between virtual applications and debuggers
by maintaining and enumerating a list of active virtual applications.
<INSERT SRC="..\..\doc\figures.doc!IMachineDebugManager">
*/
interface IMachineDebugManager;
interface IMachineDebugManagerCookie;
interface IMachineDebugManagerEvents;
interface IEnumRemoteDebugApplications;

/* <H2> Process Debug Manager </H2>

The PDM does the following:

- Synchronizes the debugging of multiple language engines.
- Maintains a tree of debuggable documents
- Merges stack frames.
- Coordinates breakpoints and stepping across language engines.
- Tracks threads.
- Maintains a debugger thread for asynchronous processing.
- Communicates with the machine debug manager and the debugger IDE.

<Issue>
 We need a way for native to run a thread into the PDM.  This way the thread can be used for expression evaluation on higher frames. Likewise native needs a way to retrieve this thread from the PDM.  Both teams are in agreement on this

*Action item*
SamMck and JimSa to define these methods and how to expose them.  ShonK should comment on feasibility as well.
</Issue>

The following are the interfaces provided by the process debug manager.

/* IDebugExpression
Abstract representation of an asynchronously evaluated expression. Normally used
by the debugger IDE to implement an immediate execution window or watch window.
Normally provided by language engines.
Note: Currently, IDebugExpression is only available from a stack frame.
In the future it will be possible to retrieve these from other contexts
 (such as debug documents).


<Issue>
 We would like to enumerate the language engine namespaces.
 We clearly need something to get the global expression context from.
 Sam and Bob pointed out many cases where there could possibly be many many namespaces.
 We need to consider how to expose something like this a bit further.
 Currently there is a namespace but the namespace is IE really since it will persist globals across LE's.  Perhaps the namespace we are looking for is HTML, but quite possibly only a smart host could provide this.
 We continued to talk about having IDebugProperty be the general containment scheme for processes, namespaces, threads etc...  I tending to agree that this is the right approach.  We need more investigation in this  area.

*Action Item*
BrianCr, BillJoy, SamMck, Philip, etc.. to continue to discuss.

To be a smart host using IDebugDocumentHelper, a host application only to do only
three two things:

(1) CoCreate an IProcessDebugManager and use it to add your application to the list
of debuggable applications.

(2) create an IDebugDocumentHelper for each host document and make the appropriate
calls to define the document name, parent document, text, and script blocks.

(3) Implement IActiveScriptSiteDebug on your IActiveScriptSite object (implemented
already for Active Scripting.  The only non-trivial method on IActiveScriptSiteDebug
simply delegates to the helper.

Additionally, the host can optionally implement IDebugDocumentHost if it needs additional
control over syntax color, document context creation, and other extended functionality.

The main limitation on the smart host helper is that can only handle documents whose contents
change or shrink after they have been added  (though documents can expand, of course.)  For
many smart hosts, however, the functionality it provides is exactly what is needed.

Below we go into each of the steps in more detail.

<H2> Create an Application Object </H2>

Before the smart host helper can be used, it is necessary to create an IDebugApplication
object to represent your application in the debugger.
The steps for creating an application object are as follows:

(1) Create an instance of the process debug manager using CoCreateInstance.
(2) Call IProcessDebugManager::CreateApplication().
(3) Set the name on the application using SetName().
(4) Add the application object to the list of debuggable applications using
AddApplication().

Below is code to do this, minus error-check and other niceties.


	CoCreateInstance(CLSID_ProcessDebugManager, NULL,
					CLSCTX_INPROC_SERVER | CLSCTX_INPROC_HANDLER | CLSCTX_LOCAL_SERVER,
					IID_IProcessDebugManager, (void **)&g_ppdm);

	g_ppdm->CreateApplication(&g_pda);
	g_pda->SetName(L"My cool application");
	g_ppdm->AddApplication(g_pda, &g_dwAppCookie);


<H2> Using IDebugDocumentHelper </H2>

The minimal sequence of steps for using the helper is as follows:

(1) For each host document, create a helper using
IProcessDebugManager::CreateDebugDocumentHelper.

(2) Call Init on the helper, giving the name, document attributes, etc.

(3) Call Attach with parent helper for the document (or NULL if the document is
the root) to define the position of the document in the tree and make it visible
to the debugger

(4) Call AddDBCSText() or AddUnicodeText() to define the text of the document.
(These can be called multiple times if document is downloaded incrementally,
as in the case of a browser.)

(5) Call DefineScriptBlock to define the ranges for each script block and the
associated script engines.

<H2> Implementing IActiveScriptSiteDebug </H2>

To implement <I> GetDocumentContextFromPosition </I>, get the helper corresponding to
the given site, then get the starting document offset for the given source context, as
follows:

	pddh->GetScriptBlockInfo(dwSourceContext, NULL, &ulStartPos, NULL);

Next, use the helper to create a new document context for the given character offset:

	pddh->CreateDebugDocumentContext(ulStartPos + uCharacterOffset, cChars, &pddcNew);

To implement <I> GetRootApplicationNode </I>, simply call IDebugApplication::GetRootNode.

To implement <I> GetDebugApplication </I>, simply return the IDebugApplication you initially
created using the process debug manager.

<H2> The optional IDebugDocumentHost interface <H2>

The host can provide an implementation of IDebugDocumentHost using IDebugDocumentHelper::SetHost
that gives it additional control over the helper.  Here are some of the key things the host
interface allows you to do:

(1) Add text using AddDeferredText so that the host doesn't have to provide the actual
characters immediately.  When the characters are really needed, the helper will call
IDebugDocumentHost::GetDeferredCharacters on the host.

(2) Override the default syntax coloring provided by the helper.  The helper will call
IDebugDocumentHost::GetScriptTextAttributes when it needs to know the coloring for a range
of characters, falling back on its default implementation if the host return E_NOTIMPL.

(3) Providing a controlling unknown for document contexts created by the helper my implementing
IDebugDocumentHost::OnCreateDocumentContext.  This allows the host to override the functionality
of the default document context implementation.

(4) Provide a path name in the file system for the document.  Some debugging UIs will use this
to permit the user to edit and save changes to the document.  IDebugDocumentHost::NotifyChanged
will be called to notify the host after the document has been saved.

 Stepping from interpreted code to native code needs additional help from the LE's. The LE's need to source an event that they are leaving the namespace.  Additionally the LE's will need to provide some PC info of either where they are going to at le


ast where they are (assuming some thin thunk prior to calling out from the namespace).  Both teams are in agreement on this.
