           Summary: Documented WinMain for D2 is wrong
           Product: D
           Version: 2.023
          Platform: PC
               URL: http://www.digitalmars.com/d/2.0/windows.html
        OS/Version: Windows
            Status: NEW
          Keywords: spec
          Severity: critical
          Priority: P2
         Component: www.digitalmars.com
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: smjg iname.com


Currently, the form of WinMain documented for D2 is the same as that for D1. 
However, it's no good.  _moduleUnitTests() doesn't exist in D2 for a start; a
more subtle yet more serious problem is that it doesn't initialise the GC
properly.

After a day or three of driving myself mad trying to figure why one of my apps
was unstable under D2, I've finally come up with a form for WinMain that seems
to work:

----------
import std.c.windows.windows;
import core.runtime;

extern (Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
      LPSTR lpCmdLine, int nCmdShow) {
    try {
        Runtime.initialize();
        runModuleUnitTests();

        return myWinMain(hInstance, hPrevInstance, lpCmdLine, nCmdShow);

    } catch (Object o) {
        MessageBoxA(null, toStringz(o.toString()),
          "Fatal Internal Error", MB_OK | MB_ICONEXCLAMATION);
        return 0;

    } finally {
        Runtime.terminate();
    }
}

Isn't proper startup code can be found in dmain2.d ?

That's exactly what Runtime.initialize and Runtime.terminate do - call the
"proper startup code".

Correction: Runtime.initialize calls the proper startup code, and
Runtime.terminate calls the proper shutdown code.

That looks about right.  I had thought that people wouldn't want unit tests run
for dynamic libraries, which is why that routine needs to be called manually. 
If this is incorrect then I can add it to Runtime.initialize() as well.  I'll
look into changing the docs.

In which case they'll compile them without --unittest - problem solved.

You're right - Runtime.initialize() ought to call runModuleUnitTests().  People
using the currently correct WinMain will find that the unit tests run twice,
but at least they just have to remove the extra call in order to fix it.

I forgot about this ticket until the release went out and I was looking 
through bugzilla for stuff to close.  It will be fixed in the next release.
