The OPAL Discussion Forum

[Andreas Adelmann <andreas.adelmann AT psi.ch>]

Dear Colleagues I would like to start a discussion on policies for the 

future  OPAL development. Please contribute.

H5 Error Handling Policy in OPAL

===========================

   h5_int64_t rc;                                                                                                                                                                                                                                         

   rc = H5WriteFileAttribInt64(H5file_m, "nAutoPhaseCavities", &nAutopPhaseCavities, 1);                                                                                                                                                 

   if(rc != H5_SUCCESS)                                                                                                       

      ERRORMSG("H5 rc= " << rc << " in " << __FILE__ << " @ line " << __LINE__ << endl);         

If for example core 2 has a problem, you will be notified like this:

Error{+2}> H5 rc= -3 in /gpfs/homefelsim/adelmann/svnwork/OPAL/src/Structure/DataSink.cpp @ line 499

With the OPAL argument --error=0 you can disable all ERRORMSG's.

Memory Handling Policy in OPAL

===========================

Basic principe, every class has to cleanup the allocated memory, either immediately in the method or in the destructor. 

However there are some exceptions (DataSink and PartBunch). Also the references in the global object OpalData

poses some problems (check out Main.cc ab the end of the file delete OPAL.getDataSink();)

Here we need a redesign in the near future.
