From 9430147ca0aab0189d7e52df97b95a0985fc0c8a Mon Sep 17 00:00:00 2001 From: Matthew DeVore Date: Thu, 27 Jun 2019 15:54:05 -0700 Subject: list-objects-filter: encapsulate filter components Encapsulate filter_fn, filter_free_fn, and filter_data into their own opaque struct. Due to opaqueness, filter_fn and filter_free_fn can no longer be accessed directly by users. Currently, all usages of filter_fn are guarded by a necessary check: (obj->flags & NOT_USER_GIVEN) && filter_fn Take the opportunity to include this check into the new function list_objects_filter__filter_object(), so that we no longer need to write this check at every caller of the filter function. Also, the init functions in list-objects-filter.c no longer need to confusingly return the filter constituents in various places (filter_fn and filter_free_fn as out parameters, and filter_data as the function's return value); they can just initialize the "struct filter" passed in.
