Hi Nicolas,



I received that report a month ago:



"we have found the OGROCISession is never released, causing a large memory leak whenever a connection is closed.


As workaround, we added in OGROCISession::~OGROCISession()



    if( hEnv )

           OCIHandleFree((dvoid *) hEnv, (ub4) OCI_HTYPE_ENV);"



But they also mention some other memory leaks without an specific location on the code.



Can you try to see if that fix the problem?



Thanks,



Ivan

Subject: [gdal-dev] OGR: memory leak in OCI driver

Dear developers,
 
                I suspect that there is a memory leak in OCI driver for OGR
               

                My simplified test case is :
 
…          

// point A
OGRRegisterAll();
 
// point B
pDS = OGRSFDriverRegistrar::Open("OCI:USER/PWD at INSTANCE:TABLE", true);
if(pDS)
     {
          OGRDataSource::DestroyDataSource(pDS);
          pDS = NULL;
     }
     else
     {
          fprintf(fOut,"Erreur Open\n");
     }
     // point C
     
OGRCleanupAll();
// point D
 
It appears that I lose memory between points B and C, and between point A and D  

 
                B = A + 4 MB
                C = A + 20 MB ( 16 MB lost)
               D = A +19 MB ( 3 more MB lost)

 
Test was done with GDAL 1.9 under windows (with Oracle 11g)
 
Can some one have an idea to find and fix this ?
 
Thank you
 
By the way,  I received « TICKET_CREATE privileges are required to perform this operation » when I tried to make a ticket (UID nicsim)
