Make abi{pkg}diff filter out changes about private types This is to address the following enhancement requests: #19588 - Add a --headers-dir1 and --headers-dir2 option to abidiff #19948 - Add --devel-pkg1 and --devel-pkg2 options to abipkgdiff When the user specifies where to find header files for two binaries (or packages) being compared, this patch generates a type suppression specification that filters out change reports about types that are defined in files that are not in the set of header files specified. The type suppression specification also suppresses change reports about changed/added/removed virtual member functions which enclosing class type matches the type suppression specification. There is a corner case that the patch handles too, and that is exhibited by the accompanying test case for abidiff. There can be a class defined by DWARF as having no source location and as being a pure declaration. This can be a class declaration that has inline virtual members only, and one or several non-defined virtual methods too. When that declaration is included in a source file, GCC generates debug info that describes that class as being a declaration-only class with no source declaration. This patch considers such a class as being non defined; you know, like a true opaque type. So it's considered being not defined in any public header file. Changes to this kind of class are thus filtered out. * include/abg-comp-filter.h: Update copyright year. * src/abg-comp-filter.cc (has_virtual_mem_fn_change): Make this static function become exported. (has_virtual_mem_fn_change): Declare new function. * include/abg-suppression.h (suppression_base::{get,set}_is_artificial): Declare new accessors. (type_suppression::get_source_locations_to_keep): Return an unordered set of strings, not a vector. Add a non-const overload. (type_suppression::set_source_locations_to_keep): Set an unordered set of strings, not a vector. * src/abg-suppression.cc (suppression_base::priv::is_artificial_): New data member. (suppression_base::priv::priv): Initialize the new data member. (suppression_base::{get,set}_is_artificial): Define new accessors. (type_suppression::priv::source_locations_to_keep_): Change the vector of strings representing source file names into unordered set of string. (type_suppression::get_source_locations_to_keep): Return an unordered set of strings, not a vector. Define a non-const overload. (type_suppression::set_source_locations_to_keep): Set an unordered set of strings, not a vector. (type_suppression::suppresses_diff): Make this suppress virtual member function diffs if the enclosing type of the changed virtual member is suppressed by the current type_suppression. (read_type_suppression): Adjust to use the fact that the source locations are not stored in an unordered set, not in a vector anymore. Otherwise, using a vector here make things too slow. (type_suppression::suppresses_type): Likewise. Also, If the type we are looking at has no location because it's a true opaque type and if the current suppression is an artificial suppression that is meant to suppress change reports about non-public types, then suppress the type. * include/abg-tools-utils.h (gen_suppr_spec_from_headers): Declare new public function. * src/abg-tools-utils.cc (PRIVATE_TYPES_SUPPR_SPEC_NAME): Define a new constant variable. (handle_fts_entry): Define new static function. (gen_suppr_spec_from_headers): Define new public function. * src/abg-comparison.cc (corpus_diff::priv::apply_suppressions_to_added_removed_fns_vars): If a type suppression suppresses a given class C, make it change added/removed virtual functions whose enclosing type is C. * tools/abidiff.cc (options::{headers_dir1, headers_dir2}): New data members. (display_usage): Add help strings for --headers-dir1 and --headers-dir2. (parse_command_line): Parse the new --headers-dir1 and --headers-dir2 options. (set_diff_context_from_opts): Generate suppression specifications to filter out changes on private types, if --headers-dir1 or --headers-dir2 is given. * tools/abipkgdiff.cc (options::{devel_package1, devel_package2}): New data members.

Bug 17649 Avoid endless looping on diff graph with cycles Bug URL: https://sourceware.org/bugzilla/show_bug.cgi?id=17649. abidiff stumbled accross a diff graph with cycles. And it kept walking that graph endlessly. Of course. It turned out on such graphs with cycles, the categorizing code that uses abigail::comparison::diff::traverse() to walk the graph and categorize the diff nodes was traversing the same class of equivalence of certain diff nodes more than once without even noticing. This patch changes the logic of the diff graph traversing code to make it always call diff_node_visitor::visit_begin() on the visitor for a diff node prior to visiting it (visiting means calling diff_node_visitor::visit()) and diff_node_visitor::visit_end() after visiting it. But when the diff node has already been visited and it's reached again by the traversing code (in case of a cycle) then the diff_node_visitor::visit_begin() is called, but diff_node_visitor::visit() is *NOT*. Then diff_node_visitor::visit_end() is called. In other words, even when the diff node is not visited (because it's already been visited) the pair diff_node_visitor::{visit_begin,visit_end}() is called. This avoids traversing the diff node (or rather the equivalence class of the diff node) more than once even in presence of cycles, but still gives a chance to custom visitors to detect that they are seeing a cycle and act accordingly if need be. This is a kind of cycle detection feature. Then the code of the (harmless and harmful categorization) filters has been adapted to always rely on the cycle detection feature. The code of the category propagation visitor has also been adapted to propagate the category of a given diff node to and from its canonical diff node. * include/abg-comp-filter.h (harm{less,ful}_filter::visit_end): Declare new methods. * include/abg-comparison.h (diff_context::maybe_apply_filters): Remove the traverse_nodes_once flag. * src/abg-comp-filter.cc (apply_filter): Force the traversing to operate in cycle avoidance mode.
