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.
