The first, dom_tree_to_commodity_ref_no_engine(), gets the two pieces of the reference (space and id) and creates a new gnc_commodity from them. The second, dom_tree_to_commodity_ref(), calls dom_tree_to_commodity_ref_no_engine() and then looks up the commodity in the engine. This has the result of only leaving 1 gnc_commodity per commodity.
Right, you only WANT 1 gnc_commodity* object per commodity. That's
exactly what you want. Similarly you only want one Account* object
per account, one Transaction* object per transaction, etc.
> In the places where commodity refs are used, dom parsers for prices and transactions call dom_tree_to_commodity_ref() but the parser for accounts calls dom_tree_to_commodity_ref_no_engine(). Can anyone explain why?
Probably because Accounts are always loaded first so you'll always have
all your commodities before you load any transactions.
