Objet : RE: [gdal-dev] OGR: memory leak in OCI driver
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@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
