Hi John,
I did all you suggested, but the problem is, it does not fail where you expect
it. This does not mean that the error is not created where you think.
With this here added as you suggested, the output is as i expected.
wxLogDebug(wxT("pushuserdatatype1 %p %p pushing %p type %d\n"),
a2dLuaWP, a2dMaskProc, obj_ptr, wxl_type);
if (wxluaO_istrackedweakobject(L, (void*)obj_ptr, wxl_type, true))
return true;
wxLogDebug(wxT("pushuserdatatype2 %p %p pushing %p type %d\n"),
a2dLuaWP, a2dMaskProc, obj_ptr, wxl_type);
========= OUTPUT ===============
14:43:47: pushuserdatatype1 020062B0 020062B0 pushing 020062B0 type 426
14:43:47: pushuserdatatype2 020062B0 020062B0 pushing 020062B0 type 426
14:44:21: pushuserdatatype1 020062B0 020062B0 pushing 020062B0 type 429
14:44:21: pushuserdatatype2 020062B0 020062B0 pushing 020062B0 type 429
First-chance exception in maskproc.exe: 0xC0000005: Access Violation.
First-chance exception in maskproc.exe (KERNEL32.DLL): 0xE06D7363: Microsoft
C++
Exception.
Here the second time the same pointer is pushed, i get the exception with the
stack dump at the end of this mail. From the output it is clear I do not have a
tracked object/pointer, because in both cases false is returned.
Now the second time the same pointer is pushed, it follows a different path in
this function here, but in both cases the return is false. But the first time
it skips the "if (lua_istable(L, -1))" part, while the second it goes in there,
but the "if (wxlua_iswxuserdata(L, -1) && (wxl_type == wxluaT_type(L,
-1)))"part
is skipped.
bool LUACALL wxluaO_istrackedweakobject(lua_State *L, void *obj_ptr, int
wxl_type, bool push_on_stack)
{
lua_pushlightuserdata(L, &wxlua_lreg_weakobjects_key); // push key
lua_rawget(L, LUA_REGISTRYINDEX); // pop key, push value (the obj table)
lua_pushlightuserdata(L, obj_ptr); // push key
lua_rawget(L, -2); // get t[key] value; pop key push value
if (lua_istable(L, -1))
{
Hope you can do something, knowing this.
