Until now, if a diff node N has a local change, even if all of its
children nodes are redundant, N is not considered as being redundant.
This is an issue if the local changes of N are filtered out; in that
case, N should be considered redundant.
This patch fixes that. It introduces a second category bitmap on the
diff node that stores the categorization of the diff node that does
*NOT* take in account the categories inherited from its children
nodes. That way, it's possible to know if the *local changes* of a
given node have been filtered out.
* include/abg-comparison.h (diff::{get_local_category,
add_to_local_category, add_to_local_and_inherited_categories,
remove_from_local_category, set_local_category,
is_filtered_out_wrt_non_inherited_categories,
has_local_changes_to_be_reported}): Declare new member functions.
* src/abg-comp-filter.cc ({harmless, harmful}_filter::{visit,
visit_end}): Update local category too.
* src/abg-comparison.cc (diff::priv::local_category_): Add new
data member.
(diff::priv::priv): Initialize it.
(diff::priv::is_filtered_out): Add new member function. This is
factorized out of diff::is_filtered_out().
(diff::is_filtered_out): Re-write in terms of
diff::priv::is_filtered_out().
(diff::{get_local_category, add_to_local_category,
add_to_local_and_inherited_categories, remove_from_local_category,
set_local_category, is_filtered_out_wrt_non_inherited_categories,
has_local_changes_to_be_reported}): Define new member functions.
(suppression_categorization_visitor::visit_begin): Update local
categories too.
(redundancy_marking_visitor::visit_end): If all of the children
nodes of the a diff node N are redundant and if N has filtered-out
local changes, then N is redundant too.
* tests/data/test-diff-filter/libtest28-redundant-and-filtered-children-nodes-v{1,2}.so:
New binary test inputs.
* tests/data/test-diff-filter/test28-redundant-and-filtered-children-nodes-v{0,1}.cc:
Source code for the binary test inputs above.
* tests/data/test-diff-filter/test28-redundant-and-filtered-children-nodes-report-{0,1}.txt:
New test output references.
* tests/test-diff-filter.cc (in_out_specs): Add the test inputs
above to the set of inputs this test harness has to run over.
* tests/data/Makefile.am: Add the test materials above to the
source distribution.
