[CELayoutEditor Update] Stack Traces, VEH & misc

Postby fjeronimo » Thu Dec 06, 2007 20:25

Hi all,

Here's another CELayoutEditor SVN update that I hope is to your liking.

The update has been tested in both VS2003 and VS2005.

Here's the detailed contents:

---------------//-----------------

- New: VEH Support - Added Vectored Exception Handling (VEH) support under Windows platforms and debug builds (this option is ignored in release builds). The VEH handler is registered at program startup and is responsible for intercepting all thrown exceptions (both CPP & SEH Win32 ones). This includes normal thrown exceptions, unhandled ones, fatal ones (like access violations) and explicitly raised ones (via RaiseException()). Thanks go to Roger Orr (see about box for contact) for all the help he provided in the process.

- New: Stack Trace - Added stack trace support if running under Windows. The stack trace mechanism includes support for multiple stack trace processing and "eaten" exceptions detection (caught but not processed/logged exceptions).Unfortunately, the code is non-portable, although plans are being made for linux support in the near future.

The following code (inserted in EditorFrame):


Code: Select all

void buh()
{
    throw CEGUI::GenericException( "A sample error..." );
}

// ------------------------------------------------------------------------
// [...]
// In EditorFrame::OnLayoutSkin

    try
    {
        buh(); // First thrown exception     
    }
    catch(CEGUI::GenericException &)
    {
        try
        {
            // Second thrown exception
            // NOTE: This will lead exceptionAddress is empty or invalid when
            // attempting to retrieve type in the VEH handler
            throw;
        }
        catch(CEGUI::GenericException &)
        {
            try
            {
                // Third thrown exception
                throw std::exception("Final exception in the chain");
            }
            SHOW_EXCEPTION("EditorFrame::OnLayoutSkin", "This is the result of a series of nested exceptions", "This is the result of a series of nested exceptions", "This is the result of a series of nested exceptions");
        }
    }

    // Cause access violation (fatal exception)
    // NOTE: This will also lead to failure when attempting to retrieve the exception type
    // in the handler, since an SEH exception class cannot be recognized
    int* p = 0;
    *p = 0;


generates the following under Windows in a debug build (with all configuration defines in Config.h set to 1):

Code: Select all

06/12/2007 19:21:37 (Error)   CEGUI::GenericException in file d:\dev\ceguitests\celayouteditor\src\editorframe.cpp(794) : A sample error...
06/12/2007 19:21:37 (Warn)   GetRTTIExceptionType - Failed to obtain exception type (exceptionAddress is empty or invalid)
06/12/2007 19:21:39 (Error)   CELayoutEditor has detected and caught an exception. The following detailed info is available:

Description: This is the result of a series of nested exceptions
Exception Location: EditorFrame::OnLayoutSkin
Exception Message: Final exception in the chain

WARNING: Multiple stacks detected. This is the result of one or more of the following three things:
   - "Eaten" exceptions (caught but not processed/logged exceptions);
   - Exception chains (the same exception is rethrown -- e.g. catch(Exception&) throw;);
   - Nested exceptions (the exception is caught and a new one is thrown).
All stack traces will be displayed (more recent first).

- New: Exception code retrieval - Added support for exception code retrieval. See 'Stack Trace' entry above for more info.

- New: Exception flags retrieval - Added support for exception flags retrieval. See 'Stack Trace' entry above for more info.

- New: Exception type retrieval - Added support for exception type retrieval (using RTTI). See 'Stack Trace' entry above for more info.

- New: Exception line & file - Added support for line and file retrieval for CEGUI exceptions. See 'Stack Trace' entry above for more info.

- New: Exception handling configuration - The new features added above are fully configurable via the defines present in Config.h (CHECK_STACK_TRACES;
SHOW_EXCEPTION_FLAGS; SHOW_EXCEPTION_CODE; SHOW_EXCEPTION_TYPE; CHECK_EATEN_EXCEPTIONS; CHECK_MULTIPLE_STACKS and APPEND_MULTIPLE_STACKS).

- New: Logger - The logger is now setup right from the start (and not only when CEGUI is initialized). This allows for the contemplation of errors when performing the CELayoutEditor setup. The log file is now named CELayoutEditor.log instead of CEGUI.log.


- Change: RTTI - Project now supports RTTI in both VS2003 and VS2005.

- Change: Lint files - Lint files have been updated.
