[xmlvm-dev] Bug in Interface vtable generation

[Markus H. <ma...@ti...>]

Hi,

I'm trying to convert a class that implements the Comparator interface with the c-backend. Unfortunately using that class as a comparator (e.g. in Arrays.sort) gives a EXC_BAD_ACCESS. In the included source snippet, you can see, that the com_sun_media_sound_ModelInstrumentComparator_compare___javax_sound_midi_Instrument_javax_sound_midi_Instrument function is bound to __TIB_com_sun_media_sound_ModelInstrumentComparator.vtable[11] . But a little bit later in the interface vtable __TIB_com_sun_media_sound_ModelInstrumentComparator.vtable[12] is used, which is unset and leads to the error. I have manually changed the 12 to 11 in that line and the code works fine after that.

void __INIT_IMPL_com_sun_media_sound_ModelInstrumentComparator()
{
    if (!__TIB_com_sun_media_sound_ModelInstrumentComparator.classInitializationBegan) {
        __TIB_com_sun_media_sound_ModelInstrumentComparator.classInitializationBegan = 1;

        // Initialize base class if necessary
        if (!__TIB_java_lang_Object.classInitialized) __INIT_IMPL_java_lang_Object();
        __TIB_com_sun_media_sound_ModelInstrumentComparator.newInstanceFunc = __NEW_INSTANCE_com_sun_media_sound_ModelInstrumentComparator;
        // Copy vtable from base class
        XMLVM_MEMCPY(__TIB_com_sun_media_sound_ModelInstrumentComparator.vtable, __TIB_java_lang_Object.vtable, sizeof(__TIB_java_lang_Object.vtable));
        // Initialize vtable for this class
        __TIB_com_sun_media_sound_ModelInstrumentComparator.vtable[11] = (VTABLE_PTR) &com_sun_media_sound_ModelInstrumentComparator_compare___javax_sound_midi_Instrument_javax_sound_midi_Instrument;
        // Initialize vtable for implementing interfaces
        __TIB_com_sun_media_sound_ModelInstrumentComparator.numImplementedInterfaces = 1;
        __TIB_com_sun_media_sound_ModelInstrumentComparator.implementedInterfaces = (__TIB_DEFINITION_TEMPLATE* (*)[1]) XMLVM_MALLOC(sizeof(__TIB_DEFINITION_TEMPLATE*) * 1);
        __INIT_IMPL_FOR_CLASS_java_util_Comparator(&__TIB_com_sun_media_sound_ModelInstrumentComparator.implementedInterfaces[0][0]);
        __TIB_com_sun_media_sound_ModelInstrumentComparator.implementedInterfaces[0][0]->vtable[11] = __TIB_com_sun_media_sound_ModelInstrumentComparator.vtable[12];
        __TIB_com_sun_media_sound_ModelInstrumentComparator.implementedInterfaces[0][0]->vtable[1] = __TIB_com_sun_media_sound_ModelInstrumentComparator.vtable[1];

        __TIB_com_sun_media_sound_ModelInstrumentComparator.declaredFields = &__field_reflection_data[0];
        __TIB_com_sun_media_sound_ModelInstrumentComparator.numDeclaredFields = sizeof(__field_reflection_data) / sizeof(XMLVM_FIELD_REFLECTION_DATA);
        __TIB_com_sun_media_sound_ModelInstrumentComparator.constructorDispatcherFunc = constructor_dispatcher;
        __TIB_com_sun_media_sound_ModelInstrumentComparator.declaredConstructors = &__constructor_reflection_data[0];
        __TIB_com_sun_media_sound_ModelInstrumentComparator.numDeclaredConstructors = sizeof(__constructor_reflection_data) / sizeof(XMLVM_CONSTRUCTOR_REFLECTION_DATA);
        __TIB_com_sun_media_sound_ModelInstrumentComparator.methodDispatcherFunc = method_dispatcher;
        __TIB_com_sun_media_sound_ModelInstrumentComparator.declaredMethods = &__method_reflection_data[0];
        __TIB_com_sun_media_sound_ModelInstrumentComparator.numDeclaredMethods = sizeof(__method_reflection_data) / sizeof(XMLVM_METHOD_REFLECTION_DATA);
        __CLASS_com_sun_media_sound_ModelInstrumentComparator = XMLVM_CREATE_CLASS_OBJECT(&__TIB_com_sun_media_sound_ModelInstrumentComparator);
        __TIB_com_sun_media_sound_ModelInstrumentComparator.clazz = __CLASS_com_sun_media_sound_ModelInstrumentComparator;
        __CLASS_com_sun_media_sound_ModelInstrumentComparator_ARRAYTYPE = XMLVM_CREATE_ARRAY_CLASS_OBJECT(__CLASS_com_sun_media_sound_ModelInstrumentComparator, 1);

        __TIB_com_sun_media_sound_ModelInstrumentComparator.classInitialized = 1;
    }
}

I don't have enough knowledge of the c backend, so I can't find the place where to correct this in the source myself...

(And yes,  you see correctly, that I'm trying to do MIDI in there :D)

Markus

Oh! I'm sorry. I thought you were another Markus!

Can you please check the review system. There is a patch by another Markus
that will probably fix your problem. We hope to commit that patch soon.

Quick question: I'm assuming you were using HEAD. Does this still happen
when you use your vtable patch?

Hi,

I applied the patch, but unfortunately I can't compile the XCode project afterwards. I get different errors every time or XCode beachballs and doesn't compile at all...

did you do an "ant clean"? You probably have an old cache on your system.

Hi,

Yes, I did ant clean in xmlvm and in my project several times.

Re: [xmlvm-dev] Bug in Interface vtable generation

[Markus H. <ma...@ti...>]

Hi,

unfortunaltly XCode now beachballs everytime if I have the vtable patch applied, so can't give you the errors I got...

But I started xmlvm (without the vtable patch) with debug output and got this for the affected class:

     [java] [03/20/11 11:02:47.869]    DEBUG: Size of vtable for class com.sun.media.sound.ModelInstrumentComparator: 13
     [java] [03/20/11 11:02:47.869]    DEBUG: Implemented interfaces: 
     [java] [03/20/11 11:02:47.869]    DEBUG:     java.util.Comparator
     [java] [03/20/11 11:02:47.869]    DEBUG:         compare: 11 = 12
     [java] [03/20/11 11:02:47.869]    DEBUG:         equals: 1 = 1
...
     [java] [03/20/11 11:02:52.066]    DEBUG: Vtable index for com.sun.media.sound.ModelInstrumentComparator.compare: 11

The funny thing is, that it is working for other classes that implement interfaces, like LinkedList etc...

Any hint where in the code I could poke around to get this fixed?

Markus

Re: [xmlvm-dev] Bug in Interface vtable generation

[Arno P. <ar...@pu...>]

the vtable patch is the way to go, although we can't commit it yet. It 
doesn't make sense to invest time and effort to fix the HEAD. One 
problem with the vtable patch is that it causes many compiler warnings 
(this will be fixed). Unfortunately Xcode doesn't behave well with many 
warnings which is probably what you meant with beachballing (get a 
rebate on those $4! ;) ). In the Xcode project settings, select "Inhibit 
all warnings" and try to compile again.

Re: [xmlvm-dev] Bug in Interface vtable generation

[Markus H. <ma...@ti...>]

Hi,

disabling the warnings does wonders to xcode4 :D

I get the following error with the table patch:

In file included from /Users/markus/Documents/workspace/Kinderlieder/dist/../build/xcode/src/app/native_java_util_Locale.m:9:
/Users/markus/Documents/workspace/Kinderlieder/dist/../build/xcode/src/lib/iphone/org_xmlvm_iphone_NSString.h:37: error: 'XMLVM_ITABLE_SIZE_org_xmlvm_iphone_NSString' undeclared here (not in a function)

Here is the relevant generated snippet. As you can see it uses XMLVM_ITABLE_SIZE_org_xmlvm_iphone_NSString, but that is not defined in the whole project. 

// Class declarations for org.xmlvm.iphone.NSString
XMLVM_DEFINE_CLASS(org_xmlvm_iphone_NSString, 6, XMLVM_ITABLE_SIZE_org_xmlvm_iphone_NSString)

Greetings,
Markus

Re: [xmlvm-dev] Bug in Interface vtable generation

[Arno P. <ar...@pu...>]

OK, here is the problem: you are using the vtable patch for an iphonec 
project. This, unfortunately, does not work (yet). The problem is that 
the vtable patch needs a "global view" on all classes. However, in order 
to make this happen the XMLVM pipeline needs some refactoring. Sascha is 
on this job and is making good progress. We'll send a ping on the 
mailing list when the refactoring is done.

Long in short: the vtable patch currently only works for --target=posix.

Arno
