2008-08-16 Sven Neumann <sven@gimp.org> If a procedure call fails, pass a string describing the error as the second return value. First step towars fixing bug #344818. * app/pdb/gimpprocedure.[ch] (gimp_procedure_get_return_values): added a GError parameter. If it is set, pass the error message to the return values. * app/pdb/gimppdberror.h: added some more error codes. * app/pdb/gimppdb.c * app/xcf/xcf.c: pass errors to gimp_procedure_get_return_values(). * app/plug-in/gimpplugin-message.c (gimp_plug_in_handle_proc_run): show a different error message for execution vs. calling errors. * app/plug-in/gimpplugin-progress.c (gimp_plug_in_progress_cancel_callback): pass the error GIMP_PDB_CANCELLED to gimp_procedure_get_return_values(). * app/plug-in/gimppluginmanager-call.[ch] (gimp_plug_in_manager_call_run): removed the 'destroy_return_vals' parameter. * app/plug-in/gimppluginprocedure.c: destroy the return values here. * app/plug-in/gimppluginprocframe.c: pass an error to gimp_procedure_get_return_values(). * tools/pdbgen/app.pl * tools/pdbgen/pdb/fileops.pdb: generate code that passes the error to gimp_procedure_get_return_values(). * app/pdb/*-cmds.c: regenerated. * plug-ins/pygimp/pygimp-pdb.c: extract the error message from the return values and pass it to the exception that is thrown. svn path=/trunk/; revision=26593
