Subject:SWIG_exception vs. SWIG_exception_fail
View as plain text  

I think we need to use SWIG_exception_fail instead of SWIG_exception.

In python they are actually defined as the same thing, but in perl 
SWIG_exception_fail does a 'goto fail;' and the croak() is done under 
fail. A plain SWIG_exception continues in the success path and doesn't 
throw an exception (it just creates the exception information but 
doesn't throw it).

With SWIG_exception,
$connection = new ndb::Ndb_cluster_connection();
if ($connection->connect(5,3,1)) {

     print "Connect to cluster management server failed.\n";
     exit -1;

actually prints
Connect to cluster management server failed.

Whereas with SWIG_exception_fail, the script dies with
RuntimeError Connect to management server failed

Which is the behaviour I assume we are looking for.

I'll provide a patch in a bit.
