Every call to create a shapeObj or getFeature function the VM crashes.

[hrodriguez@…]

Every time i want to create a shapeObj or call the getFeature function the VM
crashes.
MapServer version 4.8.1 
 example 
public List queryPorPunto(int x, int y)   {
>                 List lista = new ArrayList();
>                 pointObj p = new pointObj(x, y, 0);
>                 String row = "";
>
>                 layerObj l = map.getLayerByName("entorno");
>                 l.queryByPoint(map, p, mapscriptConstants.MS_MULTIPLE, 
> -1);
>
>                         resultCacheObj results = l.getResults();
>                         if (results == null)
>                                 return lista;
>
>                         l.open();
>                         for (int i = 0; i < results.getNumresults(); i++)
>                         {
>                                 resultCacheMemberObj r = 
> results.getResult(i);
>                                 shapeObj shape = 
> l.getFeature(r.getShapeindex(), -1);
>                                 row = "";
>                                 for (int j = 0; j <

> j++)
>                                         {

> shape.getValue(j) + "</TD>";
>                                         }
>                                 lista.add(row);

Apply the attached patch or add this statement

at about line 233 of mappostgis.c and then post the standard output here.

Please try this queryByPoint code (which works well for me on postgis):

    protected List queryLayerByPoint(int i, pointObj queryPoint) {
       List results = new ArrayList();

       layerObj layer = map.getLayer(i);
       if (layer != null && isVisible(layer)) {
           if (log.isDebugEnabled()) {
               log.debug("Querying layer: " + layer.getName());
           }
           if (layer.queryByPoint(map, queryPoint,
mapscript.MS_MULTIPLE, -1) == mapscript.MS_SUCCESS) {
               //resultCacheObj resultCache = layer.ggetResultcache();
               if (layer.open() == mapscript.MS_SUCCESS) {
                   //for (int j=0;j<resultCache.getNumresults();j++) {
                   for (int j = 0; j < layer.getNumResults(); j++) {
                       if (log.isDebugEnabled())
                           log.debug("Layer " + layer.getName() + ",
result number:" + j);
                       resultCacheMemberObj resultMember = layer.getResult(j);
                       shapeObj shape = new shapeObj(layer.getType());
                       layer.getShape(shape,
resultMember.getTileindex(), resultMember.getShapeindex());
                       if (shape != null) {
                           Map aResult = getResult(shape, layer);

                           results.add(aResult);
                       } else {
                           log.error("Shape " + j + " is null!");
                       }
                   }
                   layer.close();
               } else {
                   log.error("Cannot open layer: " + layer.getName());
               }
           } else {
               log.info("Query on layer " + layer.getName() + " failed.");
           }
       }
       return results;
   }

[szekerest]

I have found similar problems with C# on linux if support for geos was enabled.
Without geos support compiled in the problem has not come out.

Tamas

[szekerest]

Umberto,

You should enable GEOS support in java makefile.in for fixing this problem.

Tamas

[szekerest]

Fixed for C#

[unicoletti]

I have not been able to reproduce the error (even with GEOS 2.2.1 compiled in)
and the user has not answered to emails.
I'll wait another week then close as INVALID.

[szekerest]

I wonder why you haven't encounter this problem considering the followings:

1. Java makefile.in does not propagate USE_GEOS (like for C# before)
2. Compiling mapserver and mapscript with different USE_GEOS setting different
shapeObj size will be allocated for mapserver and mapscript, see the shapeObj
declaration:

typedef struct {
#ifdef SWIG
%immutable;
#endif
  int numlines;
  int numvalues;
  lineObj *line;
  char **values;
#ifdef SWIG
%mutable;
#endif

  rectObj bounds;
  int type; /* MS_SHAPE_TYPE */
  long index;
  int tileindex;
  int classindex;
  char *text;

#ifdef USE_GEOS
  void *geometry;
#endif

} shapeObj;

and the mapscript shapeObj constructor & destructor:

SWIGINTERN shapeObj *new_shapeObj(int type){
        int i;
        shapeObj *shape;

	shape = (shapeObj *)malloc(sizeof(shapeObj));
        if (!shape)
            return NULL;

        msInitShape(shape);
        if(type >= 0) shape->type = type;

        /* Allocate memory for 4 values */
        if ((shape->values = (char **)malloc(sizeof(char *)*4)) == NULL) {
            msSetError(2, "Failed to allocate memory for values", "shapeObj()");
            return NULL;
        } else {
            for (i=0; i<4; i++) shape->values[i] = strdup("");
        }
        shape->numvalues = 4;
        
        return shape;
    }
SWIGINTERN void delete_shapeObj(shapeObj *self){
        msFreeShape(self);
        free(self);		
    }

msFreeShape will want to use *geometry that was not allocated for example.
Or the reverse case may also occur.

[unicoletti]

I do not usually have MALLOC_CHECK_ set. When I set it I got the error too.

BTW: the shapeObj constructor allocates 4 values which are probably not needed.
Should we remove them?

[szekerest]

Inline shapeObj currently supports 4 value to be handled by setValue and getValue.
Values cannot be added. How about implementing "shapeObj.addValues(string[]
values)" instead of preallocating the 4 values?

[unicoletti]

I don't think we should allow users to edit shapeObj values.
Those values should be set by the datasource where the shape came from and
should not be changed (they are in fact read-only).

I am more keen on just removing the allocation of the 4 values array, which is
probably a memory leak (at lease for postgis which does not free it when it sets
its own values).

[szekerest]

I have changed the followings in the CVS-HEAD:

1. Removed the default preallocation of 4 values
2. Added initValues to achieve the similar functionality if needed.

Maybe branch-4-8 should also be changed if this issue is critical.

[unicoletti]

This bug is closed.
