2021-10-04 Dodji Seketeli Update NEWS file for 2.0 * NEWS: Update for 2.0 2021-09-23 Dodji Seketeli Bug 27086 - Consider all C++ virtual destructors when there are many * src/abg-dwarf-reader.c (build_or_get_fn_decl_if_not_suppressed): Do not try to re-use a virtual destructor of a class, based on its signature. Several different of these can have the same signature, inside a given class. * tests/data/test-types-stability/PR27086-libstdc++.so.6.0.26: Add new binary test input. * tests/data/Makefile.am: Add the new test input to source distribution. * tests/test-types-stability.cc (elf_paths): Add the test input above to this harness. 2021-09-23 Dodji Seketeli dwarf-reader: Indent * src/abg-dwarf-reader.cc (finish_member_function_reading): Fix indentation. 2021-09-22 Dodji Seketeli Bug 27970 - Duplicated member functions cause spurious self comparison changes * src/abg-dwarf-reader.cc (fixup_functions_with_no_symbols): When the function decl is finally associated to its (publicly defined) ELF symbol, mark it as being exported. (finish_member_function_reading): Don't risk marking a virtual function as being non-virtual when updating its properties. (build_or_get_fn_decl_if_not_suppressed): Update comment. If the member function is already present in the class, do not create a new one; rather, reuse the existing one. It's going to be later updated by finish_member_function_reading. * tests/data/test-annotate/test18-pr19037-libvtkRenderingLIC-6.1.so.abi: Adjust. * tests/data/test-annotate/test20-pr19025-libvtkParallelCore-6.1.so.abi: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-report-0.txt: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-report-1.txt: Likewise. * tests/data/test-diff-filter/test41-report-0.txt: Likewise. * tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-0.txt: Likewise. * tests/data/test-diff-pkg/tbb-4.1-9.20130314.fc22.x86_64--tbb-4.3-3.20141204.fc23.x86_64-report-1.txt: Likewise. * tests/data/test-read-dwarf/PR22015-libboost_iostreams.so.abi: Likewise. * tests/data/test-read-dwarf/test10-pr18818-gcc.so.abi: Likewise. * tests/data/test-read-dwarf/test18-pr19037-libvtkRenderingLIC-6.1.so.abi: Likewise. * tests/data/test-read-dwarf/test20-pr19025-libvtkParallelCore-6.1.so.abi: Likewise. * tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi: Likewise. 2021-09-21 Dodji Seketeli abipkgdiff: Do not erase working dirs before we are done using them * tools/abipkgdiff.cc (compare_prepared_userspace_packages): Removing working directories "early" prevents e.g, dwarf_reader::get_soname_of_elf_file from accessing those files. So do not remove them until the very end. * tests/data/test-diff-pkg/libxcrypt-4.1.1-6.el8.x86_64--libxcrypt-4.1.1-6.el8.x86_64-output-1.txt: Adjust. 2021-09-14 Dodji Seketeli Bug 28316 - Failure to represent typedef named anonymous enums * include/abg-fwd.h (scope_anonymous_or_typedef_named) (is_anonymous_or_typedef_named): Declare new functions. * include/abg-ir.h (decl_base::set_has_anonymous_parent): Remove declaration. (decl_base::{get,set}_naming_typedef): Declare new member functions. * src/abg-ir.cc (update_qualified_name): Define static function. (decl_base::priv::naming_typedef_): Define new data member. (decl_base::priv::has_anonymous_parent_): Remove data member. (decl_base::priv::priv): Adjust constructor. (decl_base::get_has_anonymous_parent): Rather than storing a flag for this, dynamically look at if the scope is anonymous. (decl_base::set_has_anonymous_parent): Remove definition. (decl_base::{get,set}_naming_typedef): Define new member functions. (scope_anonymous_or_typedef_named) (is_anonymous_or_typedef_named): Define new functions. (get_decl_name_for_comparison): Define new sub-routine for the decl_base overload of equals. (equals): In the overload for decl_base, use the new get_decl_name_for_comparison. It helps to ensure that all anonymous decls of the same kind have the same name for the purpose of comparison. It also ensures that non anonymous decls that are part of anonymous scopes should be compared only by looking at their non-qualified names. In the overload for class_or_union, adjust. (scope_decl::add_member_decl): No more need to flag the fast that the parent scope is anonymous here. (get_debug_representation): Fix a thinko. (class_or_union::get_naming_typedef): Remove member function as it's now handled by decl_base::get_naming_typedef. * src/abg-dwarf-reader.cc (build_typedef_type): When a typedef is a naming typedef, then mark the named decl as being typedef-named. (maybe_canonicalize_type): Delay canonicalization of anonymous types because they can be typedef-named later. * src/abg-reader.cc (read_naming_typedef_id_string) (maybe_set_naming_typedef): Define new static function. (build_class_decl): Use it here, rather than reading the "naming-typedef-id" by hand. (build_enum_type_decl, build_union_decl): Read the "naming-typedef-id" property. * src/abg-writer.cc (write_naming_typedef): Make this accept decl_base_sptr, rather than just class_decl_sptr. (write_enum_type_decl): Write the naming-typedef-id property if needed. * tests/data/test-abidiff-exit/test-PR28316-report.txt: New test reference output. * tests/data/test-abidiff-exit/test-PR28316-v{0,1}.cc: Source code of new binary test input. * tests/data/test-abidiff-exit/test-PR28316-v{0,1}.o: New binary test input files. * tests/data/Makefile.am: Add the new test files to the source distribution. * tests/test-abidiff-exit.cc: Add the new test files above to this harness. * tests/data/test-annotate/libtest23.so.abi: Adjust. * tests/data/test-annotate/libtest24-drop-fns-2.so.abi: Likewise. * tests/data/test-annotate/libtest24-drop-fns.so.abi: Likewise. * tests/data/test-annotate/test13-pr18894.so.abi: Likewise. * tests/data/test-annotate/test14-pr18893.so.abi: Likewise. * tests/data/test-annotate/test15-pr18892.so.abi: Likewise. * tests/data/test-annotate/test21-pr19092.so.abi: Likewise. * tests/data/test-diff-dwarf/test15-enum-report.txt: Likewise. * tests/data/test-diff-filter/test19-enum-report-1.txt: Likewise. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report0.txt: Likewise. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report1.txt: Likewise. * tests/data/test-diff-filter/test30-pr18904-rvalueref-report2.txt: Likewise. * tests/data/test-diff-filter/test35-pr18754-no-added-syms-report-0.txt: Likewise. * tests/data/test-diff-pkg/PR24690/PR24690-report-0.txt: Likewise. * tests/data/test-diff-pkg/nss-3.23.0-1.0.fc23.x86_64-report-0.txt: Likewise. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-0.txt: Likewise. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-1.txt: Likewise. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-2.txt: Likewise. * tests/data/test-diff-pkg/spice-server-0.12.4-19.el7.x86_64-0.12.8-1.el7.x86_64-report-3.txt: Likewise. * tests/data/test-read-dwarf/PR22015-libboost_iostreams.so.abi: Likewise. * tests/data/test-read-dwarf/PR22122-libftdc.so.abi: Likewise. * tests/data/test-read-dwarf/PR25007-sdhci.ko.abi: Likewise. * tests/data/test-read-dwarf/PR25042-libgdbm-clang-dwarf5.so.6.0.0.abi: Likewise. * tests/data/test-read-dwarf/libtest23.so.abi: Likewise. * tests/data/test-read-dwarf/libtest24-drop-fns-2.so.abi: Likewise. * tests/data/test-read-dwarf/libtest24-drop-fns.so.abi: Likewise. * tests/data/test-read-dwarf/test-libaaudio.so.abi: Likewise. * tests/data/test-read-dwarf/test-libandroid.so.abi: Likewise. * tests/data/test-read-dwarf/test10-pr18818-gcc.so.abi: Likewise. * tests/data/test-read-dwarf/test11-pr18828.so.abi: Likewise. * tests/data/test-read-dwarf/test12-pr18844.so.abi: Likewise. * tests/data/test-read-dwarf/test13-pr18894.so.abi: Likewise. * tests/data/test-read-dwarf/test14-pr18893.so.abi: Likewise. * tests/data/test-read-dwarf/test15-pr18892.so.abi: Likewise. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Likewise. * tests/data/test-read-dwarf/test21-pr19092.so.abi: Likewise. * tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi: Likewise. * tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Likewise. 2021-09-17 Dodji Seketeli abipkgdiff: Fix showing added/removed files * tools/abipkgdiff.cc (compare_prepared_userspace_packages): Do not return early if there are no binaries to compare.

This helps fix bug 2021-09-08 Dodji Seketeli ir: Fix canonical type propagation cancelling * src/abg-ir.cc (return_comparison_result): When the comparison of the current type sub-object fails, clear the potentially propagated canonical type and remove it from the set of types with non confirmed propagated canonical types. 2021-09-08 Dodji Seketeli ir: Avoid infinite loop during type canonicalization * src/abg-ir-priv.h (environment::priv::collect_types_that_depends_on): Don't try to collect a type that has already been collected. 2021-09-07 Dodji Seketeli writer: escape enum linkage name in abixml * src/abg-writer.cc (write_enum_type_decl): Escape linkage name. 2021-09-07 Dodji Seketeli RHBZ-1944096 - assertion failure during self comparison of systemd * src/abg-reader.cc (build_enum_type_decl): When strtoll detects an underflow or overflo, it sets errno to ERANGE. So take that into account. 2021-09-03 Dodji Seketeli Bug 27985 - abidiff: bad array types in report * src/abg-ir.cc (array_type_def::get_qualified_name): Use the cache for temporary qualified names when the type is not yet canonicalized.

Consolidate related comments. Reviewed-by: Matthias Maennich 2021-08-10 Dodji Seketeli RHBZ 1925886 - Compare anonymous types without qualified names * include/abg-fwd.h (is_anonymous_type): Constify this function. * src/abg-ir.cc (equals): In the overload for decl_base, do not take scope of anonymous types into account. In the overload for array_type_def do not peel of typedefs. This is not directly related to anonymous types, but it make comparison more robust against naming typedefs used for anonymous types in array elements. (get_type_name): Do not take into account the scope of anonymous types when building internal representation of types. Note that the internal representation is what is used for canonicalization. This means that all anonymous types are compared against each others during type canonicalization. * src/abg-reader.cc (build_class_decl): Do not try to re-use anonymous types, just like we already do for DWARF. * tests/data/test-annotate/test17-pr19027.so.abi: Adjust. * tests/data/test-annotate/test18-pr19037-libvtkRenderingLIC-6.1.so.abi: Likewise. * tests/data/test-annotate/test19-pr19023-libtcmalloc_and_profiler.so.abi: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-report-0.txt: Likewise. * tests/data/test-diff-filter/test31-pr18535-libstdc++-report-1.txt: Likewise. * tests/data/test-read-dwarf/PR22122-libftdc.so.abi: Likewise. * tests/data/test-read-dwarf/test-libaaudio.so.abi: Likewise. * tests/data/test-read-dwarf/test-libandroid.so.abi: Likewise. * tests/data/test-read-dwarf/test10-pr18818-gcc.so.abi: Likewise. * tests/data/test-read-dwarf/test11-pr18828.so.abi: Likewise. * tests/data/test-read-dwarf/test12-pr18844.so.abi: Likewise. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Likewise. * tests/data/test-read-dwarf/test17-pr19027.so.abi: Likewise. * tests/data/test-read-dwarf/test18-pr19037-libvtkRenderingLIC-6.1.so.abi: Likewise. * tests/data/test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi: Likewise. * tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi: Likewise. * tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Likewise. 2021-07-29 Dodji Seketeli Bug 27236 - Don't forget to emit some referenced types * include/abg-writer.h (write_translation_unit): Add a new parameter that says if we are emitting the last TU. * src/abg-writer.cc (write_translation_unit::{type_is_emitted, decl_only_type_is_emitted}): Constify these methods.

(environment::priv_): Make this public so that code in free form function from abg-ir.cc can access it. * src/abg-ir-priv.h (struct type_base::priv): Move this private structure here, from abg-ir.cc. (type_base::priv::{depends_on_recursive_type_, canonical_type_propagated_}): Added these two new data members. (type_base::priv::priv): Initialize the two new data members. (type_base::priv::{depends_on_recursive_type, set_depends_on_recursive_type, set_does_not_depend_on_recursive_type, canonical_type_propagated, set_canonical_type_propagated, clear_propagated_canonical_type}): Define new member functions.

(equals(const function_type& l, const function_type& r)): Redefine the RETURN macro using the new return_comparison_result function template. Use the new RETURN_TRUE_IF_COMPARISON_CYCLE_DETECTED and mark_types_as_being_compared functions. (equals(const class_or_union& l, const class_or_union&, change_kind*)): Likewise. (equals(const class_decl& l, const class_decl&, change_kind*)): Likewise. Because this uses another equal() function to compare the class_or_union part the type, ensure that no canonical type propagation occurs at that point. (types_are_being_compared): Remove as it's not used anymore. (maybe_propagate_canonical_type): Use the new environment::priv::propagate_ct() function here.

In the overload for pointer_type_def do not peel typedefs off from the compared pointed-to types. In the overload for typedef_decl compare the typedef as a decl as well. In the overload for var_decl, compare variables that have the same ELF symbols without taking into account their qualified name, rather than their name. Stop comparing data member without considering their names. In the overload for class_or_union, when a decl-only class that is ODR-relevant is compared against another type, assume that equality if names are equal. This is useful in environments where some TUs are ODR-relevant and others aren't. (*::get_pretty_representation): Update doxygen comments.

If yes, then define the preprocessor macro RPM_4_15. If that macro is defined then test-diff-pkg.cc can support RPMs from Fedora >= 31 as those are compressed with zstd. Earlier RPM versions don't support that compression scheme. * src/abg-dwarf-reader.cc (build_translation_unit_and_add_to_ir): Suffix the offset of the translation unit to its name when that name is "". * tests/data/test-diff-pkg/mesa-libGLU-9.0.1-3.fc33.x86_64.rpm: New binary test input. * tests/data/test-diff-pkg/mesa-libGLU-debuginfo-9.0.1-3.fc33.x86_64.rpm: Likewise. * tests/data/test-diff-pkg/mesa-libGLU-9.0.1-3.fc33.x86_64.self-check-report-0.txt: New reference output for the binary test input above. * tests/data/Makefile.am: Add the new test inputs above to source distribution. * tests/test-diff-pkg.cc (in_out_specs): Add the binary test inputs above to source distribution if we are running on an RPM version >= 4.15. 2020-11-20 Dodji Seketeli fedabipkgdiff: make --self-compare use abipkgdiff --self-check * tools/fedabipkgdiff (abipkgdiff): If the user provides the --self-compare options, generate the abipkgdiff command by using the --self-check option.

(class self_compare_task): Add new class. (prepare_package): Add a new overload that takes just one parameter. (elf_size_is_greater): Don't crash if the args are empty.

Use the new compare_to_self function to handle the --self-check option. * doc/manuals/abipkgdiff.rst: Add documentation for the new --self-check option. 2020-11-16 Dodji Seketeli Bug 26769 - Fix missing types in abixml output * include/abg-corpus.h (corpus::{record_canonical_type, lookup_canonical_type}): Remove function declarations. * src/abg-corpus-priv.h (corpus::priv::canonical_types_): Remove data member. * src/abg-corpus.cc (corpus::{record_canonical_type, lookup_canonical_type}): Remove functions. * src/abg-ir.cc (type_eligible_for_odr_based_comparison): Remove static function.

Otherwise, it means we added a variable that wasn't yet properly constructed. Also add a new overload for var_decl_sptr&. (build_var_decl): Do not add the var to its the set of exported declaration before we are sure it has been fully constructed and added to the scope it belongs. (build_class_decl): Only add *static* data members to the list of exported declarations. (handle_var_decl): A var decl seen here is a global variable declaration. Add it to the list of exported declarations. * src/abg-writer.cc (write_context::decl_only_type_is_emitted): Constify parameter.

It takes care of canonicalizing variadic parameter types. (build_function_decl): Canonicalize the function type that is created here. (build_ir_node_from_die): Use the overload of maybe_canonicalize_type which canonicalizes class_or_union nodes directly, rather than the one which handles DIE offsets. The latter was used as an optimization to reduce the size of the array of types scheduled for canonicalization, as DIE offsets take less space than pointers to IR types.

Unlike for qualified names, the scoped name won't have a "__anonymous_*__" string in its name if its directly containing scope is not anonymous; a qualified name might still have that string in its name because the decl has a parent scope (not necessarily its directly containing scope though) that is anonymous. The patch goes on to update the logic for comparison of decls that are anonymous. For a decl which direct scope is *NOT* anonymous, the scoped name is what's used in the comparison. Otherwise, only the name of the decl is used. The patch also updates how we detect changes in data members and member types, in the comparison engine. It now uses the names of the data members, rather than their qualified name. This is in the scope of the current class/union anyway. The improvement is that the fact that the class/union itself is anonymous (even if its anonymous name changes to another anonymous name) won't have any spurious impact on the detection of name change of the members. The patch considers the change of an anonymous decl name which anonymous name changes to another anonymous name as being harmless. The patch updates the logic of category propagation in the comparison engine. Although a public typedef to private underlying type needs to stay public and thus not propagate the PRIVATE_TYPE_CATEGORY from its child diff node to himself, it still needs to suppress the changes to the private underlying diff node that were suppressed (because of the private-ness), unless that typedef has local changes. * include/abg-ir.h (decl_base::get_scoped_name): Declare new member function.

We'll end up with those two libraries that are identical (modulo the order in which libabigail sees type declarations and their definitions) and are considered different when a suppression specification makes us drop T: the second library appears to libabigail as if T was removed from it. This is the problem addressed by this patch. When the definition of a type T is suppressed because it's considered private then we look if there was a forward declaration for it elsewhere, that is not matched by the private type suppression specification. If we encountered such a type declaration then it means that declaration is in effect an "opaque" version of T. So rather than just dropping T altogether, we keep (and build an IR) for its opaque version only. And we drop the definition of T. This seems to fix the issue. I can't seem to reproduce the slight re-ordering of DIEs descriptions that uncover the issue so I'll rely on integration tests to catch future regressions on this issue, rather than on unit tests.

Enhancements ============ * Pass the "task done" notifier by reference, to the worker queue. Without this, the worker queue needs to copy the "task done" notifier by value. This implies that user code needs to provide task done notifier instances that come with potentially complicated copy constructors. By passing it by reference and by just re-using the notifier from the user code, we do away with the need for copying altogether. This also fixes some latent copying bugs. * Add a workers::queue::schedule_tasks() method This allows user code to schedule a vector of tasks at once. * make workers::queue::get_completed_tasks() return a non-const vector This enables user code to sort the completed tasks as they wish. * include/abg-workers.h (queue::tasks_type): New typedef. (queue::queue): Pass task_done_notify by reference. (queue::schedule_tasks): Declare new member function. (queue::get_completed_tasks): Return non-const vector. * src/abg-workers.cc (queue::priv::default_notify): New data member. (queue::priv::notify): Make this data member be a reference. (queue::priv::priv): Initialize the notify data member to either the new default_notify (if no notifier is provided by the constructor) or to the notifier provided by the constructor. (queue::priv::schedule_task): Do not schedule a nil task. Update comment. (queue::priv::schedule_tasks): Add a new member function. (queue::priv::do_bring_workers_down): Update comment. Protect access to "bring_workers_down" with tasks_todo_mutex to prevent a data race. Call pthread_cond_broadcast on the queue_cond unconditionaly to prevent some worker threads to keep waiting for ever. Also, protect the access to the queue_cond by the queue_cond_mutex to precent a data race. (queue::queue): Pass the notifier by reference. Update comment. (queue::schedule_task): Update comment. (queue::schedule_tasks): Define new member function. (queue::wait_for_workers_to_complete): Update comment. (queue::get_completed_tasks): Return a non-const vector. Update comment.

This is not only a way to prevent infinite loops while visiting the graph, but also an optimization as it avoids walking two equivalent diff nodes. But then it can happen that we forget to categorize some diff nodes inside a given class of equivalence, even though we categorized some others. This patch makes it so that when a diff node inside a class of equivalence is categorized as SUPPRESSED, the canonical diff node of that class of equivalence is categorized as SUPPRESSED too. That way, to know if a diff node is suppressed, we just need to look at its canonical diff node. While doing this, I noticed that abidiff and abipkgdiff are not dropping private types from libabigail's internal representation, even though the Library now has that capability. The patch fixes that. But then the patch adds a --dont-drop-private-types option to abidiff to avoid dropping those private types from the IR, so that regression tests can make sure that a suppressed diff node implies suppression all equivalent nodes too. * doc/manuals/abidiff.rst b/doc/manuals/abidiff.rst: Document the new --dont-drop-private-types option. * src/abg-comparison.cc (diff::is_filtered_out): If the canonical type was suppressed then the current diff node is filtered out.

More precisely, on ppc64, the address of a function is the address of a function descriptor. The function descriptor is a set of three 64 bits addresses. The first element of the triplet is the function entry pointer address. So to get the symbol a given function entry point address belongs to, one must get to the function descriptor which contains said function entry point address. And function descriptors are in the ".opd" special section. Unfortunately, Libabigail's ELF/DWARF reader has no knowledge of all this. So it cannot get the symbol of a given function DWARF description. So it considers all functions as having no ELF symbols. So it shows no ABI change pertaining to function sub-types on ppc64. This patch makes Libabigail support function descriptors on ppc64 so it can detect changes on function sub-types there. * src/abg-dwarf-reader.cc (read_context::{opd_section_, fun_entry_addr_sym_map_}): New data members.

Ok, it does one extra save of abixml, but then that won't hurt. And things are faster now than what they were anyway :-) 2015-10-17 Dodji Seketeli Fix emitting of referenced type in abixml writer * Use of canonical pointers in the hash map of referenced types The abixml writer was using canonical types pointer values to hash referenced types in a map. It was doing so "by hand"; and it was thus messing things up for types without canonical types (like some class declarations) etc. This patch changes that by using the generic solution of abigail::ir::hash_type_or_decl(), which also uses the same canonical pointer type values. For types with no canonical types, that functions knows has to gracefully fallback. At worst, it will just make things slower, not wrong. * Sorting of referenced types The patch also changes the sorting function used for the hash map of referenced types. The previous solution was sorting the pretty representation of types; but then when two types have the same pretty representation (think, typedefs, for instance) then their relative position in the sorted result was random. This causes some stability issues, in that emitting the abixml for the same binary several times can lead to the some types being sorted differently -- they have the same name, but not necessarily the same type *IDs*, as they are different types. The new sorting code handles this better; it also uses the pretty representations of types, when they are equal, it uses the type IDs to tell the types apart. At least this brings stability in the abixml output, for a given binary. * Avoiding duplicating declaration-only types when emitting the context of referenced member types. We don't keep track of declaration-only classes that are emitted. This is because we allow a given class declaration (that carries no definition) to appear several times in a given ABI corpus. So when a referenced type is a class declaration, it always appears as if that referenced type has not been emitted. So when we specifically emit the not-emitted referenced types, it can happen that declaration-only classes can appear a lot of times. This is unnecessary duplication, aka bloat. This patch thus introduces a new hash map that tracks emitted declaration-only classes, so that we can allow duplication of class declarations when they follow what's done in the IR read from DWARF, and disallow that duplication when it's totally artificial and useless. * Better tracking of referenced types We were blatantly forgetting to mark some referenced types as such. So those were missing in some abixml output. This patch fixes the spots where we were forgetting that important information. * Better representation of the scopes of the referenced types that were specifically emitted. The previous code was failing at properly representing the class scope of some referenced types that were specifically emitted, or sometimes, for member types, representing the scope would be so screwed that the (referenced) member type itself wouldn't be emitted at all. This is because I thought that to emit a given member type, just emitting its parent scope would be enough. I thought that would automatically trigger emitting the member type itself. First, that would emit too much information at times; the other members of the scope are not necessarily needed. And second the "duplication detection code" would sometime refuse to emit the scope class, because it has already been emitted earlier! But the incarnation that got emitted didn't have this member type as member, then. Yes, in DWARF, the same class A can be declared several times with different member types in it. The complete representation of A would be a union of all those declarations of A that are seen. This patch addresses this issue by carefully emitting just the information that is needed from the scope of the referenced type. Basically the scope is declared just to declare/define the type we are interested in; period. The abixml reader is now properly geared to re-construct the scope by merging its different parts that are now scattered around, in the ABI corpus. That support is part of this patch set. instance, a member typedef would be emitted with the information of its parent class badly formatted. * src/abg-writer.cc (struct type_ptr_comp_functor): Remove this. (sort_type_ptr_map): Likewise. (write_context::record_type_as_referenced): Do not add the canonical type of the type to record as referenced directly.

(write_class_decl_opening_tag): Factorize out of ... (write_class_decl): ... here. Now, keep track also of declaration-only classes that are emitted. (write_decl_in_scope): Use the new write_member_type_opening_tag and write_class_decl_opening_tag. Now write class scopes ourselves; they only contain the type declarations that we are emitting. (write_translation_unit): Use the new sorting code to sort the referenced types to emit. Do not emit referenced types that are declaration-only classes that have already been emitted. Handle the fact that emitting the referenced types might make those emitted type *reference* other types too! So handle those new referenced types as such, and emit them too. (write_qualified_type_def, write_typedef_decl, write_var_decl): Do not forget to mark referenced types as such. 2015-10-17 Dodji Seketeli Support updating a class in the abixml reader * include/abg-ir.h (class_decl::{find_base_class, find_member_type, find_data_member}): Declare new member functions .. * src/abg-ir.cc (class_decl::{find_base_class, find_member_type, find_data_member}): ... and define them. * src/abg-reader.cc (build_class_decl): Add the ability to update a class to add new data members, member types and base classes to it, if necessary. 2015-10-17 Dodji Seketeli Don't canonicalize types not added to their context in abixml reader * src/abg-reader.cc (read_context::maybe_canonicalize_type): Assert that a class type that is scheduled for canonicalization must be in a scope. We do this only for classes, for now. The assert here helped to spot (and fix) a lot of places where we were canonicalizing types without scope. (read_context::build_or_get_type_decl): Canonicalize types here, when they are built and (hopefully) added to their scope. There might be cases here where we try to canonicalize types that are not added to their scope. That should bomb in the assert above, at least for class types, for now. We'll then fix the places where the types are created, to make them properly scoped. (build_type_decl, build_qualified_type_decl) (build_pointer_type_def, build_reference_type_def) (build_array_type_def, build_enum_type_decl, build_typedef_decl): Do not try to canonicalize the types early, right when they are created.

Also, schedule member types for canonicalization once they've been added to their scope. (build_class_tdecl): Schedule the pattern of the class template for canonicalization once it has been added to its scope. I am not sure I should do this, as the pattern is not yet a real type, but I am taking my bet. (build_type_composition): Schedule the composed type for canonicalization once it's been added to its scope. (handle_type_decl, handle_qualified_type_decl) (handle_pointer_type_def, handle_reference_type_def) (handle_function_type, handle_array_type_def) (handle_enum_type_decl, handle_typedef_decl, handle_class_decl): At this point, we should know if the type is to be added to a scope or not. If it's in a scope, then schedule for canonicalization. 2015-10-15 Dodji Seketeli Bug 19092 - abidw aborts on types that violate the ODR * src/abg-ir.cc (type_base::get_canonical_type_for): Look at the size of types with the same name which could be considered ODR-equal, to spot possible violations that would induce a type canonicalization error. * tests/data/test-read-dwarf/test21-pr19092.so: New test input binary. * tests/data/test-read-dwarf/test21-pr19092.so.abi: New reference abixml for the binary above. * tests/data/Makefile.am: Add the new test input above to source distribution. * tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Adjust. * tests/data/test-read-dwarf/test12-pr18844.so.abi: Likewise. * tests/data/test-read-dwarf/test20-pr19025-libvtkParallelCore-6.1.so.abi: Likewise. * tests/test-read-dwarf.cc (int_out_specs): Add the two test input above. 2015-10-15 Dodji Seketeli Fix activation of Debian package support * configure.ac: If we cannot activate Debian package support, then report it clearly. 2015-10-15 Dodji Seketeli Misc style cleanup * include/abg-fwd.h: Remove unnecessary declaration of class parameter. * src/abg-ir.cc: Remove trailing space in a comment. * src/abg-reader.cc: Fix a comment. 2015-10-15 Dodji Seketeli Emit statistics about resolved class declarations * src/abg-dwarf-reader.cc (read_context::resolve_declaration_only_classes): Emit statistics about resolved classes and the missed ones. 2015-10-15 Dodji Seketeli Add a missing xml text reader call * src/abg-reader.cc (read_corpus_from_input): Add the necessary call to xmlTextReaderNext call after the xmlTextReaderExpand call. 2015-10-15 Dodji Seketeli Pass some more parameters in reference * include/abg-ir.h (operator==): For the type_base_sptr and decl_base_sptr overloads, pass the parameters by reference.

If we are computing the hash value of struct list itself, then the temporary value of "struct list" is zero. But then once we are done computing the hash value of "struct list", that value becomes non-zero. Hence, the hash value of a type depends on when that value is computed. But then if we want to cache that hash value and re-use it later, which value should we cache? Definitely not the zero value! So in other words, we can use (and thus cache) the hash value of a given type T only after the hash values of all types which use T have been computed. To satisfy that condition, we decide to use the (cached) hash value of each type only after we've computed all the hash values of all types of the system. So, during type canonicalization, when a type T is canonicalized, this patch stores the hash value of T. But then it's only when all types are canonicalized that the hashing code is allowed to re-use the cached value of types. This fixes the issues of spurious type differences introduced when the same type was read either from DWARF or from abixml. Those differences where introduced by differences in the order of hashing types which sub-types refer to themselves. The patch also updates regression tests accordingly. * src/abg-dwarf-reader.cc (read_debug_info_into_corpus): Before we read debug info and build the IR, set a flag in the environment saying that type canonicalization isn't finished yet. But then, after type canonicalization is done, flip that flag to say that type canonicalization is done. * src/abg-reader.cc (read_corpus_from_input): Likewise. * src/abg-ir.cc (type_base::get_canonical_type_for): Once a type has been canonicalized, cache its hash value. * src/abg-hash.cc (type_base::dynamic_hash::operator()): If type canonicalization has been done and if the type has a cached value, use that one. * tests/data/test-read-dwarf/test2.so.abi: Adjust. * tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Likewise. * tests/data/test-read-dwarf/test10-pr18818-gcc.so.abi: Likewise. * tests/data/test-read-dwarf/test12-pr18844.so.abi: Likewise. * tests/data/test-read-dwarf/test13-pr18894.so.abi: Likewise. * tests/data/test-read-dwarf/test14-pr18893.so.abi: Likewise. * tests/data/test-read-dwarf/test15-pr18892.so.abi: Likewise. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Likewise. 2015-09-07 Dodji Seketeli Introduce the concept of environment * include/abg-ir.h: Adjust note about memory management.

(read_context::clear_per_corpus_data): Clear here the previous data that were per-tu. (read_context::maybe_canonicalize_type): Add a new force_delay flag that forces the type to be late-canonicalized. Also force late-canonicalize references, pointers, qualified-type and typedef because they must be canonicalized once they've been added to their context; but then this function might be called too early, before they are added to their context. (read_context::type_id_new_in_translation_unit): Remove this member function. (read_translation_unit_from_input): Be able to either use the xmlTextReader interface, or get the current 'abi-instr' xml element node. If using the xmlTextReader interface, use it to move to the 'abi-instr' node, expand it and then use that. In either case, call read_translation_unit() with the 'abi-instr' xml element node. (read_translation_unit): Take an 'abi-instr' XML element in argument now, use that to read the translation unit, as opposed to using the xmlTextReader interface we where using before to walk the sub-tree of the abi-instr xml node. (read_context::get_scope_for_node): If the scope is a new translation unit, then build the new translation unit. (read_symbol_db_from_input): Take the function and variable symbol data bases, and read the current xml element node (do not use the xmlTextReader interface anymore) to populate the function and variable symbols. (read_elf_needed_from_input): Do not use the xmlTextReader interface anymore. Rather, use the current xml element node, look for the 'elf-needed' xml element node and use it to populate the set of elf dependencies. (read_corpus_from_input): Rework to expand the contents of the corpus node and use the result, rather than just exclusively relying on the xmlTextReader interface. (build_function_parameter): Build a proper IR node for variadic parameters. Build function type node *after* having built all the parameters IR, so that parameter indexing is the same as what is done in the DWARF reader. Also, if the function is not being added to its context yet, then delay the canonicalizing of its type, just like what is done by the DWARF reader. (build_qualified_type_decl, build_pointer_type_def) (build_reference_type_def, build_enum_type_decl, build_type_decl): Adjust. Do not enforce anymore that the ID of this type be new in the current TU. Delay canonicalizing if the type is not being added to its context. For typedefs, use an adapted way of checking the consistency of the underlying type. (build_array_type_def): Do not enforce anymore that the ID of this type be new in the current TU. Support the fact that the array might not have any DW_AT_byte_size attribute. Force late canonicalizing if the array is not being added to its context. (build_class_decl): Adjust. Reuse the read_context::maybe_canonicalize_type() function rather than trying to determine locally when to canonicalize. (build_template_tparameter): Adjust 2015-08-29 Dodji Seketeli Fix handling of class declaration during DWARF reading *virtual* member functions, data members, base classes or a DW_AT_byte_size as being conditions for being defined. * src/abg-dwarf-reader.cc (read_context::decl_only_classes_map_): Remove this data member. (read_context::{declaration_only_classes_to_force_defined, schedule_declaration_only_class_for_forced_resolution}): Remove these member functions. (read_context::resolve_declaration_only_classes): Do not force resolution of class declaration. (build_class_type_and_add_to_ir): Do not schedule classes for forced-resolution when they are used as base classes. The presence of a member function is not enough to make the class be defined. It needs to be a virtual member function. 2015-08-28 Dodji Seketeli Fix important hashing issues * src/abg-hash.cc (class_decl::hash::operator()): Do not force base classes to have definitions anymore. GCC and Clang (at least) some time emits debug info in which the definition of some base classes are missing, especially when those base classes have vtables. In that case, the definition of the class might it's in the binary where the vtable is emitted, which might not be the binary we are looking at. So let's relax the assertion we had here for base classes. For hashing virtual member functions, directly walk the virtual member functions by looking at class_decl::get_virtual_mem_fns() rather than walking all member functions and looking for the virtual ones. This is a speed optimization but it also helps during debugging. 2015-08-28 Dodji Seketeli Fix template comparison operators * include/abg-ir.h (function_tdecl::operator==): Introduce a new virtual member operator that takes a function_tdecl&. * src/abg-ir.cc (class_decl::member_function_template::operator==): Avoid the static cast in the overload for member_base. In the overload for member_class_template, avoid infinite recursion. (function_tdecl::operator==): In the overload for decl_base, do not do the real work here in the overload for decl_base Rather, the real work is done in the new overload for function_tdecl, and all other overloads call that one. 2015-08-28 Dodji Seketeli Use size/alignment of class definition when requested on declaration * include/abg-ir.h (type_base::{set_size_in_bits, set_alignment_in_bits}): Make these member functions virtual.

(fqn_to_components): Use the new function above to break up a fully qualified name into components, rather than the too simple string::find_first_of() we were using previously.

(corpus_diff::priv::diff_stats_): Turn this data member into a [shared] pointer to diff_stats. (corpus_diff::priv::filters_and_suppr_applied_): Remove this data member. Now that diff_stats_ is a pointer, we don't need this boolean anymore. (corpus_diff::apply_filters_and_suppressions_before_reporting): Adjust to the fact that filters_and_suppr_applied_ is gone, and that diff_stats_ is now a pointer.

(get_typedef_diff_underlying_type_diff): Define new function. (type_suppression::suppresses_diff): After looking through the different kind of access methods, use the new type_suppression::suppresses_type(), rather than doing lots of stuff ourselves here. But then, if the suppression doesn't apply to the subjects of the diff, look through typedefs and try to apply the suppression again. * src/abg-ir.cc (get_typedef_underlying_type): Define new function. * tests/data/test-diff-suppr/libtest25-typedef-v{0,1}.so: New binary test input files. * tests/data/test-diff-suppr/test25-typedef-v{0,1}.c: Source code for the binary test input files above. * tests/data/test-diff-suppr/test25-typedef-report-{0, 1}.txt: New test input files. * tests/data/test-diff-suppr/test25-typedef-suppr-0.txt: New test input file. * tests/data/Makefile.am: Add the new test material to the source distribution. * tests/test-diff-suppr.cc (in_out_specs): Add the test inputs above to the set of test inputs this harness has to run over. 2015-07-24 Dodji Seketeli Make abipkgdiff erase the *parent* directory of temporary files * tools/abipkgdiff.cc (erase_created_temporary_directories_parent): New static function.

Add an overload that takes an elf_symbol. * src/abg-corpus.cc (find_symbol_by_version): New static function. (corpus::{lookup_function_symbol, lookup_variable_symbol}): Take a elf_symbol::version object, rather than a string representing the version. Add an overload that takes an elf_symbol. If the looked up symbol has no version and if the corpus contains a symbol with the same name and with a default version, then return that latter symbol if the corpus doesn't contain a symbol with the same name and empty version. * src/abg-comparison.cc (class_diff::ensure_lookup_tables_populated): Adjust. (corpus_diff::priv::ensure_lookup_tables_populated): Before deciding that a symbol has been added, if the symbol has a default version, make sure no symbol with the same name and without version was present in the former corpus. Similarly, before deciding that a symbol has been removed, if the symbol has no version, make sure the latter corpus has no symbol with the same name and with a default version. * tests/data/test-diff-dwarf/test12-report.txt: Adjust. The function should not be considered as added, because its symbol (and version) was already present in the former DSO. 2015-07-24 Dodji Seketeli Fix a thinko in removed variables detection * src/abg-comparison.cc (corpus_diff::priv::ensure_lookup_tables_populated): Once we have computed a set of potentially deleted variables that turned out to contain variables that were actually *NOT* deleted, really take these into account by removing these false positives from the set of deleted *variables*. We were trying to delete these from the set deleted *functions*; woops, I guess this was a copy & paste error. 2015-07-24 Dodji Seketeli Fix logic of type_has_non_canonicalized_subtype() * src/abg-ir.cc (type_has_non_canonicalized_subtype): Once the type has been traversed, just test if the visitor has accumulated the 'has_non_canonical_type' property. 2015-07-24 Dodji Seketeli Fix style issues * include/abg-ir.h (struct ir_node_visitor): Fix the wording of the comment of this type. * src/abg-dwarf-reader.cc (build_ir_node_from_die): Fix the filling of the text of the comment of the code that chooses to perform early canonicalizing. 2015-07-24 Dodji Seketeli Adding member type doesn't reset declaration-only-ness of a class * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Adding a new member type shouldn't remove the declaration-only-ness of the class. 2015-07-22 Dodji Seketeli Extract all packages for a given run of abipkgdiff under the same temp dir * tools/abipkgdiff.cc (package::{}): Make the data members be private.

(synthesize_function_type_from_translation_unit): Make the translation_unit parameter non-const because the function needs to bind the life time of the synthesized function to the life time of the translation unit. Make this function be a friend of abigail::ir::translation_unit. (synthesize_function_type_from_translation_unit): * src/abg-ir.cc (translation_unit::priv::synthesized_types_): New data member. (synthesize_type_from_translation_unit): Define new function. (synthesize_function_type_from_translation_unit): Make the translation_unit parameter non-const. If the return is void, then take that in account carefuly. Rather than just looking up the type of parameters and return value, synthesize them too, especially when they are qualified types. Bind the life time of the synthesized function type to the lifetime of the translation unit. * tests/data/test-abicompat/test7-fn-changed-report-1.txt: New test reference output. * tests/test-abicompat.cc (in_out_spec): Run the harness on the exisiting test7-fn-changed-app and libtest7-fn-changed-libapp-v1 but in weak mode this time. 2015-07-20 Dodji Seketeli Clean up the output of abicompat weak mode * tools/abicompat.cc (perform_compat_check_in_weak_mode): Remove disgracious vertical spaces in the wording. * tests/data/test-abicompat/test5-fn-changed-report-0.txt: Adjust. * tests/data/test-abicompat/test6-var-changed-report-0.txt: Adjust. 2015-07-20 Sinny Kumari Display --suppressions|--suppr option in help usage * tools/abipkgdiff.cc (display_usage): Print --suppressions|--suppr option in help usage 2015-07-20 Dodji Seketeli Fix computing the set of exported functions and varible symbols * src/abg-ir.cc (elf_symbol::get_name_and_version_from_id): Always set the version and name of the symbol. * src/abg-corpus.cc (corpus::exported_decls_builder::{keep_wrt_id_of_fns_to_keep, keep_wrt_id_of_vars_to_keep}): Reset the symbol name *and* version before passing it. This is redundant with the fix in elf_symbol::get_name_and_version_from_id() that always set the symbol name and version now, but I felt it makes it easier to understand the fix overall. * tests/data/test-abicompat/libtest7-fn-changed-libapp-v{0,1}.so: New test input binaries. * tests/data/test-abicompat/test7-fn-changed-app: Likewise. * tests/data/test-abicompat/test7-fn-changed-{app, libapp-v0, libapp-v1}.c: Source code of the binary test inputs above. * * tests/data/test-abicompat/test7-fn-changed-{libapp-v0, libapp-v1}.h: Likewise. * tests/data/test-abicompat/test7-fn-changed-report-0.txt: Test input. * tests/data/Makefile.am: Add the new test material above to source distribution. * tests/test-abicompat.cc (int_out_specs): Add the test inputs above to the set of inputs this test harness has to run over. 2015-07-20 Dodji Seketeli Fix the wording of description of abipkgdiff.cc again * tools/abipkgdiff.cc: Fix the wording again. 2015-07-20 Dodji Seketeli Remove use of tmpnam from abilint * include/abg-tools-utils.h (abigail::tools_utils::temp_file): Declare new type.

(struct options, ): Add apidoc for these types. (options::{erase_extraction_directory, erase_extraction_directories}, display_usage, extract_rpm) (erase_created_temporary_directories, extract_package) (file_tree_walker_callback_fn, compare) (create_maps_of_package_content) (extract_package_and_map_its_content, prepare_packages, compare) (parse_command_line): Add apidoc for these functions. 2015-07-15 Dodji Seketeli Various style fixes * abipkgdiff.cc (get_soname_of_elf_file): Fix spacing. * tools/abipkgdiff.cc (elf_file_paths): Make this global variable static. (extract_rpm): Rename parameter pkg_path name into package_path. 2015-07-15 Dodji Seketeli Remove the last direct fiddling with ELF from abipkgdiff.cc * abg-dwarf-reader.h (enum elf_type): Move this declaration here from abipkgdiff.cc to here. (get_type_of_elf_file): Declare this new function. (get_soname_from_elf): Change this to take a path to the elf file rather than a Elf* handler. So now to use this, the user doesn't have to get her hand dirty with elfutils. * src/abg-dwarf-reader.cc (get_soname_from_elf): Change this to take a path to the elf file rather than a Elf* handler. (elf_file_type): Move this static function here, from abipkgdiff.cc. (get_type_of_elf_file): New function. This has been factorized out of create_maps_of_package_content() in abipkgdiff.cc. * tools/abipkgdiff.cc (class elf_file): Changed struct elf_file into this. Make the default constructor private. (elf_file::elf_file): Change the constructor to just take the path to the elf_file. The base name, soname and elf file type are now computed from the path file, in the constructor. This makes instantiation much much easier from the point of view of the user of the type. (struct abi_diff): Renamed struct abi_changes into this. (abi_diff::has_changes): Define new member function. (abi_diffs): Remove this global variable. (package::package): Remove the elf file type from the set of parameters of this constructor. Rather, compute that elf file type from the path to the elf file, in the constructor. Again, this eases the use of the type. (elf_file_type): Remove this from here, as it got moved to abg-dwarf-reader.cc. (compare): In the elf_file overload, return true if the comparison yields ABI changes. (create_maps_of_package_content): Do not fiddle with elfutils stuff here. Rather, just instantiate elf_file and the analyzing of the file magically happens. (compare): Make the package overload take an abi_diff as output parameter, rather than populating a global variable in return. (compare): Add an other overload for package that doesn't take the abi_diff as output parameter and write it in terms of the previous one. (main): Adjust as the instantiation of package is now simpler. 2015-07-08 Dodji Seketeli Add a --verbose option to abipkgdiff * tools/abipkgdiff.cc (verbose): Add a new global variable. (package::erase_extraction_directory, extract_rpm, compare) (create_maps_of_package_content): Emit verbose information. (parse_command_line): Parse the --verbose option. 2015-07-08 Dodji Seketeli Use the library to implement ABI comparison in abipkgdiff * tools/abipkgdiff.cc (compare): In the overload for elf_file, use abigail::comparison::compute_diff() to compare the ABI of two corpora. The corpora themselves is read using abigail::dwarf_reader::read_corpus_from_elf(). This cleans up the output of the tool because nothing is emitted to standard output if the two ABI corpora compares equal. 2015-07-08 Dodji Seketeli Fix several string passing issues in abipkgdiff.cc * tools/abipkgdiff.cc (elf_file::elf_file): Pass the strings by reference. Also, change the order of the parameters; all the strings are passed first, then the elf_type is passed last. (package::package): Likewise, pass the strings by reference, not by value. (create_maps_of_package_content): Adjust for the change in parameters order of elf_file::elf_file. 2015-07-08 Dodji Seketeli Only try to compare DSOs or executable binaries in abipkgdiff * tools/abipkgdiff.cc (compare): In the overload for packages, only compare binaries that are DSO or executable. 2015-07-08 Dodji Seketeli Avoid flushing the output stream in abipkgdiff.cc * tools/abipkgdiff.cc (extract_package) (create_maps_of_package_content, compare, main): Avoid flushing the output stream arbitrarily. 2015-07-08 Sinny Kumari Move get_soname() function to abg-dwarf-reader.h/cc * include/abg-dwarf-reader.h (get_soname_from_elf): Declare new function * src/abg-dwarf-reader.cc (get_soname_from_elf): Define new function * tools/abipkgdiff.cc (get_soname): Remove function (pkg_diff): Call get_soname_from_elf() instead of get_soname() 2015-07-07 Dodji Seketeli Important organizational changes in abipkgdiff.cc * Avoid using shortened names when the line is not too long. * Use shared_ptr when possible. * When a function parameter is not meant to be nil, do not pass it as a pointer; rather, pass it as a reference. * Avoid doing things that can "fail" in a destructor; e.g, spawning a process. Also, it's not common practise to cleanup a resource in a type destructor, when that resource has not been created in one of the member functions of the type. It eases maintenance when resource creation and cleanup is performed at the same logical level. * tools/abipkgdiff.cc (option::package{1,2}): Rename option::pkg{1,2} into this, to increase legibility. (option::debug_package{1,2}): Likewise, rename option::debug_pkg{1,2} into this. (elf_file::~elf_file): Do not "delete this" in a destructor. This leads to double free. It's when someone invokes the "delete" operator on a pointer to the object that the destructor of the object is executed automatically; so if in the destructor the delete operator is called again, bad things are going to happen. As the destructor is now empty, remove it altogether. (elf_file_sptr): New typedef for shared_ptr. (package::path): Rename package::pkg_path into this, for better legibility. (package::extracted_package_dir_path): Rename package::extracted_pkg_dir_path into this. (package::type): Rename package::pkg_type into this. (package::is_debug_info): Rename package::is_debuginfo_pkg into this. (package::path_elf_file_sptr_map): Rename package::dir_elf_files_map into this because this is a map of path -> elf_file_sptr. Also, now the value of the map element is a elf_file_sptr, no more an elf_file*. (package::debug_info_package): Rename package::debuginfo_pkg into this. (package::package): Adjust for the changes above. (package::{erase_extraction_directory, erase_extraction_directories}): New member functions. (elf_file_paths): Renamed dir_elf_files_path into this. (erase_created_temporary_directories) (create_maps_of_package_content) (extract_package_and_map_its_content, prepare_packages): New static functions. (get_soname, elf_file_type, extract_rpm): Make this static. (extract_package): Take a const package& rather than a package_sptr to express that the function really expects a non-nil object by reference (not by copy) and that the object won't be modified. Using a reference removes the possibility that the pointer could be nil, causing crashes in the code where parameter->something was used. Now only parameter.something can be used, so no crash possible there. This is more solid code. (file_tree_walker_callback_fn): Rename callback() into this. It makes the code more legible and kind of 'self-documented'. At least you get the hint that this is a callback function for some file tree walking (ftw) function. Adjust for the relevant names renaming above. (compare): Rename compute_abidiff into this; again, this increases legibility; at least at the point of use of this function. Rename compare_package() into a an overload of compare() as well. compare_package() used to take a vector of packages. It was hard to guess by reading the signature of the function, which element of the vector is expected to be the first vector of the comparison, which one is to be the second, etc. Now, this function takes two packages, named first_package and second_package. That is more "typed"; that is, the signature is more meaningful. Greater legibility, hopefully. And in the body of the function, the debug information packages are now accessed using the package::debug_info_package data member. Again, this is less surprising, I believe. Also, explicitly erase the temporary files that were created during this comparison. All this simplifies the logic of this function, hopefully. (parse_command_line): Make this static. Add new --d1 and --d2 command line switches that are shortcuts of --debug-info-pkg1 and --debug-info-pkg2. Adjust this function for the relevant name changes above. Make lines be shorter than 80 characters. (main): Do not create any vector of parameters anymore as the compare_packages() function don't take any vector of parameter anymore. Just instantiate first_package and second_package now. Adjust for the relevant name changes above. This hopefully simplifies the logic of this function. 2015-07-06 Dodji Seketeli Wording fixes in abipkgdiff.cc * tools/abipkgdiff.cc (extract_package): Renamed extract_pkg into this because shortening 'package' into 'pkg' provides no legibility improvement. (compare_packages): Renamed pkg_diff() into this, so that the name of the function starts with a verb, and the shortened 'pkg' word is renamed back to the 'package' word. This way, the code almost reads like normal English sentences with verbs and complement, thus enhancing legibility and easing latter maintenance. (main): Adjust for the changes above. 2015-07-06 Dodji Seketeli Re-indent tools/abipkgdiff.cc * tools/abipkgdiff.cc: Re-indent the file properly and fix some white spacing here and there. 2015-07-06 Dodji Seketeli Some slight typo and wording fixes in abipkgdiff * tools/abipkgdiff.cc (display_usage): Fixed the typo in 'bi-pacakge.' Also, refer to 'package', not to 'bi-package' that is surprising to the user at first. (compute_abidiff): Shorten the size of the introductory line. 2015-07-03 Dodji Seketeli Remove names of unused variables in callback() * tools/abipkgdiff.cc (callback): Remove the name of parameters st and flag. 2015-07-03 Dodji Seketeli Remove useless const from the declaration of extract_rpm() * tools/abipkgdiff.cc (extract_rpm): Remove useless const qualifier. 2015-07-03 Dodji Seketeli End all branches of get_soname() finish with a return statement * tools/abipkgdiff.cc (get_soname): Have just one return statement at the end of this function. 2015-07-03 Dodji Seketeli Fix abipkgdiff compilation issues * tools/abipkgdiff.cc (elf_file::elf_file): Initialize data member in the same order as they were declared. (package::package): Likewise. 2015-06-19 Sinny Kumari Exclude processing symlink, display removed/added binaries between two packages * tools/abipkgdiff.cc (abi_changes): Declare new struct (callback): Exclude symbloic link file for durther processing (compute_abidiff): Consider SONAME if exists as key in map instead of binary name, else binary as key. Also, print if removed/added binaries exist between packages 2015-06-09 Sinny Kumari Stdout ABI changes if same binary found in both package * tools/abipkgdiff.cc (compute_abidiff): New function tools/abipkgdiff.cc (pkg_diff): Iterate through list of binaries in both package directory and call compute_diff function if same binary found in both file. tools/abipkgdiff.cc (main): Also consider debug-info directories avilable in debu-info packages. 2015-06-02 Sinny Kumari Save ELF files, their type and SONAME if exist for extracted packages * tools/abipkgdiff.cc (elf_type): Declare new enum (elf_file): Declare new struct (package): Add member variable dir_elf_files_map (get_soname): Define new function (elf_file_type): Define new function (extract_rpm): Iterate over extracted directory files and filter ELF binary files along with their information like name, soname, elf_type and save in dir_elf_files_map 2015-05-26 Sinny Kumari Extract packages(RPMs) into temporary directories for further processing * tools/abipkgdiff.cc (struct package): Declare new struct (package_sptr): Declare shared_ptr for struct package (extract_rpm): Define new fuction to extract rpm package (extract_pkg): Define new function to extract pacakge (pkg_diff): Define new function to get ABI diff between two packages (main): Create new object of type pacakge for each binary and debuginfo pacakge passed in commandline options 2015-05-21 Sinny Kumari Guess RPM file type * include/abg-tools-utils.h (file_type): Added member FILE_TYPE_RPM and FILE_TYPE_SRPM (operator<<): New function declaration. * src/abg-tools-utils.cc (file_type): Detect RPM and SRPM file type (operator<<): New function definition * tools/abidiff.cc (main): Check for RPM and SRPM file type as well. * tools/abilint.cci (main): Check for RPM and SRPM file type as well. * tools/abipkgdiff.cc (main): Check whether input files to abipkgdiff are valid RPM files or not. 2015-05-19 Sinny Kumari Initial skeleton of abipkgdiff tool * tools/Makefile.am: Include abipkgdiff.cc in compilation and generate abipkgdiff binary. * tools/abipkgdiff.cc: New file 2015-07-16 Dodji Seketeli Support reading binaries that do not have a symbol table * src/abg-dwarf-reader.cc (read_context::find_symbol_table_section): Allow returning a nil pointer to symbol table.

Just looking at the is_member flag is enough. So the issue arises when for instance, we are reading a class that defines a member typedef (or enum) and uses that enum as the type of a data member. When reading that data member (before reading the definition of the typedef), we read the type of the data member; so we hit the typedef. But build_ir_node_from_die() cannot fully construct the scope of the typedef before handing off the typedef because we are currently building it! So it hands out a non-complete version of the class that is being built; 'is_member' is not set to 'true' because we are getting the type of the data member; it's not *necessarily* a member type. So we need to check !is_class_type(scope) to know if we are given a member type. I am now thinking that the "is_member" flag is actually useless. I think I'll remove it in a later patch. Anyway, this fixes 'abidiff libabigail.so libabigail.so' again. I have some stashed patches that brings it's time down to ~ 45 seconds. So we are getting close to being able to include that *ultimate* test in regression test suite. Oh well. * src/abg-dwarf-reader.cc (build_ir_node_from_die): When building typedefs, enum and memeber classes, check that the scope is a member class to detect if we are building a member type. In which case the caller is going to handle the canonicalizing of the member type *after* it's access specification has been adjusted. Otherwise, that adjustments happens after the type has been canonicalized and bad things happen at comparison type. 2015-02-21 Dodji Seketeli Bug 17649 Avoid endless looping on diff graph with cycles * 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. (harm{less,ful}_filter::visit): Update the category of the canonical node too. (harm{less,ful}_filter::visit_end): Define new method. * src/abg-comparison.cc (diff_context::maybe_apply_filters): Remove the traverse_nodes_once flag. Adjust. Simplify logic. (diff::traverse): Always call diff_node_visitor::{begin,end}. If the node has already been visited previously then do not call diff_node_visitor::visit() and do not visit the children nodes. (category_propagation_visitor::visit_end): If the node has already been visited, then propagate the category from the canonical nodes of the children nodes. (propagate_categories): Force the traversing to operate in cycle avoidance mode. 2015-02-20 Dodji Seketeli Add missing new line after reporting alignment changes * src/abg-comparison.cc (distinct_diff::report): After calling report_size_and_alignment_changes, one needs to add a new line if some stuff got emitted out the output stream. 2015-02-20 Dodji Seketeli Add type checking overloads that ease their calling from GDB * include/abg-fwd.h (is_class_type, is_pointer, is_reference_type) (is_qualified_type): Declare overloads that take naked (non-smart) pointers. * src/abg-ir.cc (is_class_type, is_pointer, is_reference_type) (is_qualified_type): Define overloads that take naked (non-smart) pointers. 2015-02-20 Dodji Seketeli Remove overly eager assert in distinct_diff::report * src/abg-comparison.cc (distinct_diff::report): Remove over-eager assert. 2015-02-20 Dodji Seketeli Factorize late canonicalizing code in the dwarf reader * src/abg-dwarf-reader.cc (read_context::{canonicalize_types_scheduled, perform_late_type_canonicalizing}): Factorize these from ...

Also, add some sanity checking code in there.

Adjust set to false when calling build_ir_node_from_die() to build a function_decl. 2015-02-20 Dodji Seketeli Simplify canonicalizing handling for typedefs * src/abg-dwarf-reader.cc (build_ir_node_from_die): For typedefs, we don't need to test that the current scope is a class to know that we are looking at a member type. Just looking at the is_member flag is enough. 2015-02-20 Dodji Seketeli Do not miss canonicalizing opportunities on non-member class types * src/abg-dwarf-reader.cc (build_ir_node_from_die): When a class is not a member type, then it at least ought to be scheduled for late canonicalizing. 2015-02-20 Dodji Seketeli Fix handling of canonicalizing of member enum types * src/abg-dwarf-reader.cc (build_ir_node_from_die): Once we've built the enum type by calling build_enum_type(), do not try to canonicalize it here if it's a member type. The calling build_class_type_and_add_to_ir() must deal with it already. 2015-02-20 Dodji Seketeli Stick qualified, pointer, reference and array types into the global scope * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Do not consider qualified, pointer, reference and array types as member types. Only typedef, class and enum types are.

(build_ir_node_for_void_type): Canonicalize the void type. 2015-02-20 Dodji Seketeli Do not forget to associate DIE to the types they represent * src/abg-dwarf-reader.cc (build_type_decl, build_enum_type) (build_qualified_type, build_pointer_type_def) (build_reference_type, build_typedef_type) (build_class_type_and_add_to_ir): Take a new flag that says if the DIE is from the alternate debug info section or not. Perform the DIE->type association in these functions. Note that in build_class_type_and_add_to_ir we are now doing the DIE->type association even for declaration-only classes. And for member types, do not bother doing the association because it's already been done by build_ir_node_from_die(). (build_ir_node_from_die): Do not do the DIE->type association here anymore. Adjust to the new signature of the build_* functions above that actually build the types. 2015-02-20 Dodji Seketeli Clear per-TU data before reading debub info for a TU * src/abg-dwarf-reader.cc (read_context::die_type_map): New accessor for the two DIE->Type maps we have; the one of the main debug info section and the one of the alternate debug info section. (read_context::{associate_die_to_type, lookup_type_from_die_offset}): use the new die_type_map() accessor. (read_context::clear_per_translation_unit_data): Factorize this from build_translation_unit_and_add_to_ir(). Also, add code to clear the DIE->type map as well as the vectors of offsets of the types of the DIEs to canonicalize after the translation unit has been read. 2015-02-19 Dodji Seketeli Fix the new regression test for type canonicalizing * tests/runtestcanonicalizetypes.sh.in (binaries): Refer to abg-tools-utils, not abg-tools-utils.o; the extension is computed automatically, depending on the underlying platform. 2015-02-19 Dodji Seketeli Make strip_typedef() act on canonical types only * include/abg-fwd.h (is_compatible_with_class_type): Declare new function. (canonicalize): Move the declaration here, from ... * include/abg-ir.h (canonicalize): ... here. * src/abg-ir.cc (strip_typedef): Assert that the input type is canonicalized. Make sure that weak references are on canonicalized types. Make sure that the returned type is a canonical one. (canonicalize): Make this return the canonical type that it has computed. * src/abg-comp-filter.cc (type_size_changed): Use the new is_compatible_with_class_type() function, instead of is_class_type(). 2015-02-18 Dodji Seketeli Speed up function_decl::get_id() and var_decl::get_id() * src/abg-ir.cc (var_decl::priv::id_): New data member.

({type_base, scope_type_decl, function_type, class_decl::base_spec}::traverse): New method. (type_base::get_canonical_type_for): Handle the case of the type already having a canonical type.

(equals(const class_decl&, const class_decl&, change_kind*)): If the containing translation unit is not constructed yet, do not take virtual member functions in account when comparing the classes. This is because when reading from DWARF, there can be DIEs that change the number of virtual member functions after the DIE of the class. So one needs to start taking virtual members into account only after the translation unit has been constructed. (class non_canonicalized_subtype_detector): Define new type. (type_has_non_canonicalized_subtype): Define new function. * src/abg-corpus.cc (symtab_build_visitor_type::visit): Renamed this into symtab_build_visitor_type::visit_end. * src/abg-dwarf-reader.cc (die_type_map_type): New typedef.

(maybe_canonicalize_type): Define new function. (build_ir_node_from_die): Take a new flag that says if the ir node is a member type/function or not. Early-canonicalize base types. Canonicalize composite types that have only canonicalized sub-types. Schedule the other types for late canonicalizing. For class types, early canonicalize those that are non-member types, that are fully constructed and that have only canonicalized sub-types. Adjust to the new signature of build_ir_node_from_die.

(read_context::clear_per_translation_unit_data): Call read_context::clear_types_to_canonicalize(). (read_translation_unit_from_input): Call read_context::perform_late_type_canonicalizing() at the end of the function. (build_function_decl): Fix the function type canonicalizing (per translation) that was already in place. Do the canonicalizing of these only when the type is fully built. Oops. This was really brokend. Also, when the function type is constructed, consider it for type canonicalizing. (build_type_decl): Early canonicalize basic types. (build_qualified_type_decl, build_pointer_type_def) (build_pointer_type_def, build_reference_type_def) (build_array_type_def, build_enum_type_decl, build_typedef_decl): Handle the canonicalizing for these composite types: either early or late. (build_class_decl): Likewise. Also, mark this class a 'being built' until it's fully built. This helps the canonicalizing code to know that it should leave a class alone until it's fully built. * tests/test-ir-walker.cc (struct name_printing_visitor): Adjust to the visitor methods naming change. * configure.ac: Generate the tests/runtestcanonicalizetypes.sh testing script from tests/runtestcanonicalizetypes.sh.in. * tests/runtestcanonicalizetypes.sh.in: Add the template for the new runtestcanonicalizetypes.sh script that test for type canonicalizing. * tests/Makefile.am: Add the new runtestcanonicalizetypes.sh regression testing script to the build system. 2015-02-18 Dodji Seketeli Factorize per TU data clearing in the xml-abi reader * src/abg-reader.cc (read_context::clear_per_translation_unit_data): Factorize this function out of ... (read_context::read_translation_unit_from_input): ... this one. 2015-02-13 Dodji Seketeli Use the deep type sptr equality operator when possible * src/abg-ir.cc (equals): On function_decl overload, use the deep sptr type equality operator when comparing types. (non_type_tparameter::operator==): Likewise. 2015-02-18 Dodji Seketeli Properly compare virtualness of member functions * src/abg-ir.cc (equals(const function_decl&, const function_decl&, change_kind*)): Compare virtualness of member function before comparing their vtable offsets. 2015-02-13 Dodji Seketeli Misc style fixes * include/abg-ir.h (reference_type_def::get_pointed_to_type): use type_base_sptr, rather than shared_ptr (typdef_decl::get_underlying_type): Likewise.

(build_qualified_type_decl) (build_pointer_type_def, build_reference_type_def) (build_array_type_def, build_typedef_decl, build_class_decl): Use the is_ functions here, rather than using the dynamic cast. This increases maintainability. 2015-02-11 Dodji Seketeli Optimize compressed debug info reading for speed * src/abg-dwarf-reader.cc (find_last_import_unit_point_before_die): Look for the inclusion point of the partial unit in reverse topological order. 2015-02-10 Dodji Seketeli Share private data of class_diff nodes * src/abg-comparison.cc (class_diff::class_diff): Do not initialize the private data of class_diff here. (compute_diff): In the overload for class_diff, initialize the private data of the new instance of class_diff to the private data of its canonical instance. (redundancy_marking_visitor::visit_begin): If a node is marked redundant, do not dare visit its children. In cases of classes that have members that reference themselves, this prevents us from wrongly marking some of the data member changes as being redundant. 2015-02-10 Dodji Seketeli Do not crash when applying filters to a NULL diff * src/abg-comparison.cc (diff_context::maybe_apply_filters): Do not crash when called with a NULL diff. 2015-02-09 Dodji Seketeli Initial implementation of canonical type comparison in the IR * include/abg-ir.h (class type_base): Pimplify this class.

Do this on all the overloads' declarations. * src/abg-ir.cc (equal): Do the same for the definitions of the overloads and adapt them to report about the kind of changes makes the two ABI artifact different -- only if the change_kind pointer is non-null.

It was to determine if traversal was to be done in a pre or post manner. But with the recent addition of diff_node_visitor::visit_{begin,end}() notifiers, the pre/post handling is taken care of in a different way. So now the meaning of this enum is changed to handle whether diff node children should be visited or not. So the enumerators are now DEFAULT_VISITING_KIND, and SKIP_CHILDREN_VISITING_KIND.

So nuke the code that was dealing with it. (redundancy_marking_visitor::skip_children_nodes_): New data member flag. (redundancy_marking_visitor::visit_begin): If the current diff node is not be reported (is filtered out), do not bother visit its children nodes for the purpose of marking redundant nodes. So use the new skip_children_nodes_ flag above to know we are in that case. (redundancy_marking_visitor::visit_end): Unset the new skip_children_nodes_ flag above when appropriate. * include/abg-fwd.h (is_function_decl): Declare new function. * include/abg-ir.h (function_type::get_parm_at_index_from_first_non_implicit_parm): Declare new member function. * src/abg-ir.cc (is_function_decl): Define new function.

Also, when we bail out because we detect that there is a comparison underway, do *not* unmark the current class as not being involved in the comparison. Also, break at the first lhs virtual member function that is different from the rhs counter part. 2014-10-15 Dodji Seketeli Update the manual for the suppression specification initial work * doc/manuals/abidiff.rst: Add documentation for the new --suppressions command line switch.

(decl_base::{g,s}et_is_public_symbol_table): (class_decl::hashing_started): Remove this as we now have decl_base::hashing_started. (decl_base::{hash_, hashing_started, location_, context_, name_, qualified_parent_name_, qualified_name_, mangled_name_, visibility_}): Move all these members into the new ... * src/abg-ir.cc (struct decl_base::priv): ... pimpl type. (decl_base::decl_base): Move these out-of-line here. Adjust the other overloads. (decl_base::{hashing_started, peek_hash_value, peek_qualified_name, set_qualified_name}): Define these new protected methods.

(harmless_filter): Categorize base classes added or removed. * tests/data/test-diff-dwarf/test8-report.txt: New test input. * tests/data/test-diff-dwarf/test8-v0.cc: Likewise. * tests/data/test-diff-dwarf/test8-v0.o: Likewise. * tests/data/test-diff-dwarf/test8-v1.cc: Likewise. * tests/data/test-diff-dwarf/test8-v1.o: Likewise. * tests/data/test-diff-filter/test13-report.txt: New test input. * tests/data/test-diff-filter/test13-v0.cc: Likewise. * tests/data/test-diff-filter/test13-v0.o: Likewise. * tests/data/test-diff-filter/test13-v1.cc: Likewise. * tests/data/test-diff-filter/test13-v1.o: Likewise. * tests/Makefile.am: Add the new files above to the source distribution. * tests/test-diff-dwarf.cc: Use the new relevant input above to run more tests. * tests/test-diff-filter.cc: Likewise. 2014-04-17 Dodji Seketeli Fix class diff reporting issues for base classes * src/abg-comparison.cc (class_diff::report): For base classes, report their pretty representation. Do not try to report a the diff of a changed base class that got filtered out. Avoid emitting too many vertical white spaces. 2014-04-17 Dodji Seketeli Simplify SIZE_OR_OFFSET_CHANGE_CATEGORY categorizing * src/abg-comp-filter.cc (harmful_filter::visit): Now that type_size_changed is correctly geared to not be fulled by decl-only classes, there is no need for its caller to handle that case. And data_member_offset_changed ain't affected by decl-only classes anyway. So the code is now much simpler. 2014-04-17 Dodji Seketeli Fix API doc for static_data_member_type_size_changed * src/abg-comp-filter.cc (static_data_member_type_size_changed): Fix API doc comment. 2014-04-17 Dodji Seketeli Don't blindly drop DIEs defined in the scope of a function * src/abg-dwarf-reader.cc (get_scope_for_die): Do not drop a DIE on the floor just because it is in the scope of a function. We were dropping a function parameter because its type is a typedef defined right before the parameter, in the scope of the function. Urgh. So with this change, that function parameter is not dropped anymore. I have seen that happening in a DWARF generated by GCC 4.7.1 on libstdc++.so. Hard to come up with a regression test case for this one. 2014-04-17 Dodji Seketeli Useless code killing * src/abg-comparison.cc (decls_equal::operator()(const decls_type, const decls_type)): Kill dead code. Note that there is a proper equality operator for decl_base_sptr already. 2014-04-17 Dodji Seketeli File static data member changes in STATIC_DATA_MEMBER_CHANGE_CATEGORY * include/abg-comparison.h (diff_category::STATIC_DATA_MEMBER_CHANGE_CATEGORY): New category.

Oops. * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Let's consider that a data member being not laid out (i.e, not having a data_member_location) is is a static data member. Otherwise, we were not detecting static data members at all. Well we were only inferring their presence from seeing the static variable definition later on. That means we were missing most of the static variables. Woops. * src/abg-comparison.cc (corpus_diff::priv::ensure_lookup_tables_populated): Now that we are really seeing static data members, let's be prepare to the fact that we can the same static data member being declared several times in a corpus. * tests/data/test-diff-dwarf/test7-report.txt: New test input file. * tests/data/test-diff-dwarf/test7-v0.cc: Likewise. * tests/data/test-diff-dwarf/test7-v0.o: Likewise. * tests/data/test-diff-dwarf/test7-v1.cc: Likewise. * tests/data/test-diff-dwarf/test7-v1.o: Likewise. * tests/test-diff-dwarf.cc: Update this to consume the new test input files. * tests/Makefile.am: Update this to add the missing test files to the source distribution. 2014-04-16 Dodji Seketeli Add dumping routines for declaration location * include/abg-fwd.h (get_global_scope()): New overload for const decl_base&. Move the other overloads up in the file. (get_translation_unit): Add an overload for decl_base&. Constify the others. (dump_decl_location): Declare new functions. * src/abg-ir.cc (get_global_scope): Define the overload for const decl_base&. Write the other overloads in terms of this one. (get_translation_unit): Likewise, define the overload for const decl_base&. Write the other overloads in terms of this one. (dump_decl_location): Define these new overloads. 2014-04-16 Dodji Seketeli Fix dumping function to make them use generic ostream * src/abg-writer.cc (dump(const decl_base_sptr, std::ostream&)): Do not dump the content to cerr here. Rather dump to the output stream given in parameter. Oops. (dump(const translation_unit&, std::ostream&)): Likewise. 2014-04-16 Dodji Seketeli Misc style fixes * src/abg-ir.cc (get_translation_unit): Remove useless vertical white space. (is_global_scope): Add missing API doc. 2014-04-16 Dodji Seketeli A virt mem fn deleted and added to the same offset is not harmful * src/abg-comp-filter.cc (has_virtual_mem_fn_change): A virtual member that gets deleted and added back again to the same vtable offset is not considered as being a virtual member function change suitable for VIRTUAL_MEMBER_CHANGE_CATEGORY. Likewise for a function sub-type change not involving a change in the vtable offset. 2014-04-16 Dodji Seketeli Do not categorize size/offset changes when a decl-only class is involved * src/abg-comp-filter.cc (there_is_a_decl_only_class) (diff_involves_decl_only_class): New static functions. (type_size_changed, data_member_added_or_removed) (has_virtual_mem_fn_change, has_non_virtual_mem_fn_change): Bail out if one of the types involved is a decl-only class. 2014-04-16 Dodji Seketeli Work around "mangled name vanishing from one version of mem fn decl" bug * src/abg-comparison.cc (class_diff::ensure_lookup_tables_populated): If the first version of the member function decl doesn't have a mangled name while the second has it, try the lookups using the pretty representation of the function. 2014-04-16 Dodji Seketeli Do not try to represent the offset for a static data member * src/abg-comparison.cc (represent_data_member(var_decl_sptr, ostream&)): If the data member is static, do not try to represent its offset. 2014-04-16 Dodji Seketeli A static data member shouldn't be checked for having been laid out * src/abg-comparison.cc (represent_data_member(var_decl_sptr, ostream&)): If the data member is static do not check for it having been laid out. 2014-04-16 Dodji Seketeli Prefix pretty representation of static data members with 'static' * src/abg-ir.cc (var_decl::get_pretty_representation): Prefix pretty representation of static data members with 'static'. 2014-04-16 Dodji Seketeli Provide a robust way of getting the size of a qualified type * include/abg-ir.h (qualified_type_def::get_size_in_bits): Declare new member function ... * src/abg-ir.cc (qualified_type_def::get_size_in_bits): ... and define it. Keep in mind that some times the size of the underlying type can change between the moment the qualified type is created and the end of its life time. That is because a subsequent DIE (from DWARF) can alter the size of the underlying type. This overload allows the user to always query the size of the underlying type and keep the size of the qualified type in sync with it. 2014-04-16 Dodji Seketeli Add an assert to the pointer diff reporting code * src/abg-comparison.cc (pointer_diff::report): If the pointer diff node is deemed to be reported then the underlying diff node should be reported as well. 2014-04-16 Dodji Seketeli Little style adjustment in diff node categorization code * src/abg-comp-filter.cc (harmful_filter::visit): Factorize the categorization into SIZE_OR_OFFSET_CHANGE_CATEGORY for data member adding or removal and for data member type size change. 2014-04-15 Dodji Seketeli If a diff node is in NO_CHANGE_CATEGORY do not report it anymore * src/abg-comparison.cc (diff::is_filtered_out): Now that we seem to be flagging every changes to a class into a category, we do not need to dive into reporting a diff not that is categorized as NO_CHANGE_CATEGORY anymore. So let's have the implementation that one would expect for this function. 2014-04-15 Dodji Seketeli Categorize changes to virt mem fncts as VIRTUAL_MEMBER_CHANGE_CATEGORY * src/abg-comp-filter.cc (has_virtual_mem_fn_change): New static function. (harmful_filter): Categorize changes to virtual member functions into VIRTUAL_MEMBER_CHANGE_CATEGORY. * src/abg-comparison.cc (class_diff::priv::count_filtered_changed_dm): Move this up, right after class_diff::priv::count_filtered_subtype_changed_dm.

(compute_diff): Consider virtual member functions only, not non-virtual ones. * src/abg-ir.cc (class_decl::operator==): Do not compare non-virtual member functions. Only compare virtual member functions. * tests/data/test-bidiff/test-struct1-report.txt: New test input. * tests/data/test-diff-dwarf/test0-report.txt: New test input. * tests/data/test-diff-filter/test0-report.txt: New test input. * tests/data/test-diff-filter/test01-report.txt: New test input. * tests/data/test-diff-filter/test10-report.txt: New test input. * tests/data/test-diff-filter/test11-report.txt: New test input. * tests/data/test-diff-filter/test2-report.txt: New test input. * tests/data/test-diff-filter/test9-report.txt: New test input. 2014-04-14 Dodji Seketeli Recognize virtual member functions better and store them appart * include/abg-fwd.h (set_member_function_is_virtual): Declare new function. * include/abg-ir.h (class class_decl): Declare set_member_function_is_virtual and member_function_is_virtual as friends of class_decl.

(class_decl::operator==): Harden inf-loop prevention during class comparison using the new priv::mark/unmark_as_being_compared() functions. Now comparison of a class really compares member functions again. And it is *slooow*. I should probably change this to compare only virtual member functions. But at least this should be correct and robust for now. * tests/data/test-diff-filter/test0-report.txt: Adjust. * test01-report.txt: Adjust. 2014-04-11 Dodji Seketeli Remove the parent member of the diff node * include/abg-comparison.h (diff::parent_): Remove.

({scope_decl, var_decl, non_type_tparameter, type_composition, class_decl}::get_hash): Provide new overloads of the get_hash. * src/abg-hash.cc ({type_decl, scope_type_decl, qualified_type_def, pointer_type_def, reference_type_def, enum_type_decl, typedef_decl, var_decl, function_decl}::hash::operator()): If the hash is being calculated, do not use the not-yet fully calculated hash value. Rather, calculate the hash, cache it and return the value. ({class_decl, non_type_tparameter}::hash::operator()): Moved the {class_decl, non_type_tparameter}::hash declaration out of here and stick it in include/abg-ir.h. Keep the definition of the hashing operators here though. (type_composition::hash::operator()): New operator definition. * src/abg-ir.cc ({scope_decl, var_decl, class_decl, non_type_tparameter, type_composition}::get_hash): Define new virtual overload. 2014-04-08 Dodji Seketeli Fix mis-hashing of base specifiers and function_decl during comparison * include/abg-ir.h (function_decl::get_hash): Declare new virtual overload. * src/abg-hash.cc (class_decl::base_spec::hash::operator()): Properly hash the base specifier so that it doesn't collide with hashing a class. * src/abg-ir.cc (decl_base::get_hash): Abort if we detect a missing overload for this; (function_decl::get_hash() const): Implement this missing overload, allowing using the virtual decl_base::get_hash for function_decl. 2014-04-08 Dodji Seketeli Properly place opening quote and add missing closing quote in report * src/abg-comparison.cc (corpus_diff::report): Move the [{A,D}] marker before the opening quote.

(build_ir_node_from_die): When the scope is NULL, just drop the whole thing on the floor. 2014-04-08 Dodji Seketeli Fix the static data member recognition hack * src/abg-dwarf-reader.cc (build_translation_unit_and_add_to_ir): When trying to recognize the global var_decl as being definition variables for static data members, lookup the declaration for the data member in the relevant class. If found, then just flag the var_decl for the data member as being static; no need to add a var_decl as data member in that case, that would duplicate the data member. 2014-04-08 Dodji Seketeli Fix looking up a node inside a class * src/abg-ir.cc (lookup_node_in_scope): Do not forget to actually look at the class members. Sigh. 2014-04-07 Dodji Seketeli Work around old dwarf producers forgetting mangled names for functions * src/abg-comparison.cc (corpus_diff::priv::ensure_lookup_tables_populated): If lookup using mangled name for a deleted function yields nada, try the lookup with the pretty representation for the function. 2014-04-07 Dodji Seketeli Make type_base::get_{size,alignment}_in_bits virtual * include/abg-ir.h (type_base::get_{size,alignment}_in_bits): Make this virtual. (typedef_decl::get_{size,alignment}_in_bits): Add new member functions. Get the size,alignment from the underlying type and update the current size/alignment if they differ. Keep in mind that the size of an underlying class_decl can change over its lifetime, given how the dwarf reader reads the type information, i.e, there can be a DIE for a class type with no size information that will lead to the creation of a class_decl with size zero. Later during the DWARF reading process, another DIE will supplement the type information, adding size information to that class_decl. In between, a typedef_decl might have been created with the first version of the class_decl that has a zero size. I guess this should be extended to the other type constructs that have an underlying type (qualified types, references and pointers). 2014-04-07 Dodji Seketeli Look through typedefs when setting SIZE_OR_OFFSET_CHANGE_CATEGORY * include/abg-fwd.h (is_class_type): Declare new functions. * src/abg-comp-filter.cc (harmful_filter::visit): Use the above to convert a type into a class. * src/abg-ir.cc (is_class_type): Define the new function. 2014-04-06 Dodji Seketeli Add a new DECL_NAME_CHANGE_CATEGORY change category * include/abg-comparison.h (enum diff_category::DECL_NAME_CHANGE_CATEGORY): New enumerator. * src/abg-comparison.cc (report_name_size_and_alignment_changes) ({enum, typedef}_diff::report): Adjust to avoid emitting name change report if the DECL_NAME_CHANGE_CATEGORY category of change is currently disallowed. * abg-comp-filter.cc (decl_name_changed): New static function.

(function_decl_diff::report): Avoid using the removed_parms_ data member that was removed above. 2014-02-21 Dodji Seketeli Put the setter of access specifiers in class_decl::member_base * include/abg-ir.h (class_decl::member_base::set_access_specifier): Put the setter for access specifier here, where it belongs ... (class_decl::member_type::set_access_specifier): ... not here. 2014-02-21 Dodji Seketeli First approach to avoid duplication of IR nodes for forward-declared classes * src/abg-dwarf-reader.cc (is_declaration_only): Put this back (I removed it earlier). (build_class_type_and_add_to_ir): If the class is a declaration-only (a forward declaration), do not add a new declaration only IR node. 2014-02-21 Dodji Seketeli Do not forget to set the indexes of fn parms * include/abg-ir.h (function_type::function_type): In the constructor that takes a vector of parms, walk the vector and set the indexes of the parms. 2014-02-19 Dodji Seketeli Misc diff reporting output cleanup * src/abg-comparison.cc (function_decl_diff::report): Do not talk about changed function anymore. Rather, say that some indirect sub-types changed in the function. 2014-02-19 Dodji Seketeli Do not forget some member types/functions we built IR nodes for * src/abg-dwarf-reader.cc (build_class_type_and_add_to_ir): Associate the member type IR node to the offset of the die of the member type. (build_ir_node_from_die): For a DW_TAG_subprogram DIE that has a DW_AT_specification pointing to another subprogram DIE, associate the offset of this DIE to the IR node of that other DIE. 2014-02-19 Dodji Seketeli Better support of static member variables * include/abg-fwd.h (fqn_to_components) (lookup_type_in_translation_unit, demangle_cplus_mangled_name): Declare new public entry points * src/abg-comparison.cc (corpus_diff::report): Report stuff about global variables using their mangled name, and demangle them. If there is no mangled name for the variable, then use its pretty representation.

(build_translation_unit_and_add_to_ir): If there is what appears to be a definition of a static member variable variable -- this is in case this definition lacks the DW_AT_specification attribute that links it to the DW_TAG_member or DW_TAG_variable DIE that is a child of the right class/structure DIE -- that is not at the right place in the DIE tree, remove it from the its current place in the tree and try to hang it off of the right DIE. To do this, de-mangle its mangled name, look at what is supposed to be the parent class name, look it up in the translation unit IR, and if found, stick the variable IR node in there, as a static member variable. If not found, then bad luck. (build_class_type_and_add_to_ir): Do not try to see if a member variable is static here as the way I was doing it was unreliable. Build the data member node directly w/o going through building a variable node first. Register the data member in the die offset -> IR node map. (build_ir_node_from_die): When seeing DW_TAG_variable, look for a DW_AT_specification attribute. If there is one, then it points to a the DIE of a data member and means that data member is static. Flag the IR node of that data member as static thus. Update the die offset -> IR node map. If there is no DW_AT_specification attribute or if it doesn't point to a data member DIE, schedule this variable tag for a stage when after the whole IR is built for the translation unit, the variable's mangled named is inspected, its hypothetical parent struct/class is looked up and the variable IR node is put into the node of the right struct/class IR node. * src/abg-ir.cc (enum lookup_entity_kind): New.

Make --noout really work for when reading from dwarf. 2014-01-17 Dodji Seketeli Read .abi files with types used before being defined & lots of fixes * src/abg-reader.cc (read_context::m_decls_stack): Make this is a std::deque, rather than a std::stack. (read_context::{get_id_xml_node_map, clear_id_xml_node_map, get_xml_node_decl_map, map_xml_node_to_decl, get_decl_for_xml_node, clear_xml_node_decl_map, map_id_and_node, get_xml_node_from_id, get_scope_for_node, build_or_get_type_decl}): New member functions. (read_context::{get_cur_decl, push_decl, pop_decl}): Update this now that the decl stack uses a std::deque. (read_context::clear_decls_stack): New. (read_context::get_translation_unit): Use the first decl of the decl stack, that is most certainly the global scope of the current translation unit, to get the translation unit. (read_context::key_type_decl): Take a new flag to force the re-keying; that is set an id to a new type, even if the id was already set to a type. (read_context::push_and_key_type_decl): Assert that a type must have a declaration. (handle_*): Make these return the decl_base_sptr resulting from the parsing of the xml node, rather than just a bool. (walk_xml_node_to_map_type_ids): New static function. (read_translation_unit_from_input): Read the abi-instr xml sub-tree once, just to build an id->xml node map. That way, when a declaration needs a type what is not yet defined, it can just get its XML node, build the type from it and use it. Do not forget to advance the xml reader cursor when the reading of the 'abi-instr' sub-tree is read. Clear all the new maps we have used for the current translation unit. (handle_element_node): Cleanup logic. (build_namespace_decl): Update the new xml node -> decl map, and use it to avoid building the same namespace twice. (build_function_parameter): Do not even try to get the type of a variadic parameter. (build_function_decl, build_var_decl): Support types that are defined later.

(build_class_type_and_add_to_ir): If the class being currently built is a member class, do not loose that information after it has been added to its scope. Also, base types and types of member variables can be member types and should retain that information.

(build_pointer_type_def, build_reference_type, build_typedef_type) (build_var_decl, build_function_decl): Likewise. 2014-01-17 Dodji Seketeli Fix hashing of member types * include/abg-ir.h (class_decl::{member_function_template, member_class_template}): Make these inherit from decl_base, to comply with class_decl::member_type.

(class_decl::{member_base, member_type, data_member, member_function, member_function_template, member_class_template}::hash::operator()): define these out of line here. (type_base::dynamic_hash::operator()): Update this to hash member things. * src/abg-writer.cc (write_qualified_type_def) (write_pointer_type_def, write_class_decl) (write_reference_type_def, write_enum_type_decl): Add an overload that takes the type ID to use in the serialization.

(ses_len, compute_diff): Add a new overload that uses a default_eq_functor as comparison functor, to avoid breaking existing client code. * src/abg-diff-utils.cc (compute_middle_snake): Adjust the call to the compute_middle_snake. 2013-12-23 Dodji Seketeli Change ir node visitor interface work on pointer to nodes * include/abg-ir.h (ir_traversable_base): New type to be the base of IR nodes that are to be traversed. Extends traversable_base. Its ir_traversable_base::traversable() method takes an ir_node_visitor&. (ir_node_visitor::visit): Change these virtual overloads to take pointers to IR nodes, rather than references. This will be useful to e.g, store these IR nodes in containers on the side for some algorithms to work. That is going to be useful later to, e.g. build symbol tables on the side, using the visitor interface. (class decl_base): Make this inherit ir_traversable_base. * src/abg-ir.cc (*::traverse): Adjust comments and the call the ir_node_visitor::visit call. Use the ir_traversable_base type rather than traversable_base. (ir_traversable_base::traverse): Define.

(build_class_type_and_add_to_ir): Rename build_class_type into this. Handle adding the class to the IR and to the relevant maps. During the creation of the class, arrange for build_ir_node_from_die on the current DIE to return a declaration-only class, representing the declaration for the class that is being constructed. This breaks circular dependencies induced by decls/types that refer to the class being built, before the class is fully built and has a (logical) type ID. Once the class is created, make it refer to the class declaration that was previously handed for the requests to the class DIE. Now requests to the class DIE will just yield the newly built class. Add support for member functions and member types. (build_corpus): Support reading the dwarf version and stick it into the context.

Adjust for the rename to build_translation_unit_and_add_to_ir. (build_ir_node_from_die): Add a scope parm.

(class_decl::{remove_member_decl, remove_member_type): Likewise. * src/abg-dwarf-reader.cc (die_decl_map_type): Change this map type so that the value is now a DIE offset, rather than a DIE. This is because many times the lifetime of DIEs is shorter than the one of the reader_context. Also, the die offset uniquely designates a physical DIE even if several different instances of logical DIE might point to it. (struct die_hash): Remove this as it's useless now that we store DIE offsets in the map. (build_translation_unit): Call build_ir_node_from_die w/o setting the called_from_public_decl flag.

For DW_TAG_base_type case, use the new canonicalize_and_insert_type_into_ir to insert the type at the right place in the global scope making sure it is seen before the current scope. For pointer, references and qualified types, use canonicalize_and_insert_type_into_ir to add the type at the same scope as its underlying type. Handle DW_TAG_{namespace,module} using the new build_namespace_decl_and_add_to_ir function. Add some vertical spaces and some assertions. * src/abg-ir.cc (scope_decl::add_member_decl): Use scope_decl_sptr typedef.

(class_diff::{clear_lookup_tables, lookup_tables_empty, ensure_lookup_tables_populated}): Define new methods. (class_diff::report): Detect and report when a base class or a member type has changed, as opposed to just saying that it has been removed and inserted. Fix the rest of the function to avoid emitting useless vertical space and avoid saying that the class has "zero" insertion/deletion of a given kind of member. (scope_diff::report): avoid saying that the scope has "zero" insertion/deletion of a given kind of member. Avoid useless vertical spaces. (type_decl_diff::report): Avoid useless vertical spaces. 2013-11-19 Dodji Seketeli Add bilint tool to validate bi files somewhat. * tools/bilint.cc: New file. * tools/Makefile.am: Build and install the new file above. 2013-11-19 Dodji Seketeli Add diff support for typedef_decl and type_decl * include/abg-ir.h (operator<<(std::ostream&, decl_base::visibility)): Declare new streaming operator. * src/abg-ir.cc (operator<<(std::ostream&, decl_base::visibility)): Define it.

This to be able to call decl_base::set_scope from class_decl. (scope_decl::add_member_decl): Make this virtual protected, so that it can be called (virtually) from e.g, class_decl. (type_decl_sptr, typedef_decl_sptr): New convenience typedefs. (class_decl::add_member_decl): New virtual overload for scope_decl::add_member_decl.

(class_decl::add_member_decl): New method. (class_decl::add_member_type): Avoid silently added a new member type when that member type has already been (perhaps inadvertently) added to a scope already. Rather, put a strict assert in place there. Also add a new overload that constructs the member type out of a classic type and adds it to the class. (class_decl::{add_data_member, add_member_function}): Likewise. (class_decl::{add_member_function_template, add_member_class_template}): Avoid silently added a new member template when that template has already been (perhaps inadvertently) added to a scope already. Rather, put a strict assert in place there. * src/abg-reader.cc (push_decl_to_current_scope): Take a an extra flag saying if the current decl should be added to the current scope as well (in addition to being pushed onto the stack of scopes maintained in the reader context). (push_and_key_type_decl): Likewise, take that extra flag and pass it to push_decl_to_current_scope. (build_function_decl, build_var_decl, build_type_decl) (build_qualified_type_decl, build_pointer_type_def) (build_reference_type_def, build_enum_type_decl, build_typedef_decl) (build_function_tdecl, build_class_tdecl): Likewise. (build_class_decl): Likewise. When building member data, types, and functions, make sure /not/ to add the data, type of function to the current scope before adding it to the class_decl. This was making the member not being added to the class because it already had a scope. (build_type_tparameter, build_type_composition) (build_non_type_tparameter, build_template_tparameter) (build_type): Adjust to add the template parm to the current scope explicitly, like previously. (handle_type_decl): Use build_type_decl function. Add the type_decl to the current scope, like previously. (handle_namespace_decl, handle_qualified_type_decl) (handle_pointer_type_def, handle_reference_type_def) (handle_enum_type_decl, handle_typedef_decl, handle_var_decl) (handle_function_decl, handle_class_decl, handle_function_tdecl) (handle_class_tdecl): Adjust to add the decl to the current scope, like previously. * tests/data/test-read-write/test21.xml: New test input with member type(def). 2013-10-24 Dodji Seketeli Avoid tabs and add const/virtual/offsets to class member diff reports * include/abg-ir.h (class_decl::get_num_virtual_functions): New declaration. * src/abg-ir.cc (class_decl::get_num_virtual_functions): New definition.

The offset is an index into a table; it's not a value in bits. * src/abg-hash.cc (class_decl::member_function::hash): Update wrt function name change above. * src/abg-ir.cc (class_decl::member_function::operator==): Likewise. * src/abg-reader.cc (build_class_decl): Rename the attribute vtable-offset-in-bits into vtable-offset. * src/abg-writer.cc (write_voffset): New function. (write_class_decl): Use the new write_voffset. Cleanup. 2013-10-24 Dodji Seketeli White space and style fixes * include/abg-ir.h (class_decl::member_function::member_function): Align function parameters. * src/abg-ir.cc (type_decl::operator==): Remove useless white spaces 2013-10-24 Dodji Seketeli Do not report added/removed type_decls * src/abg-comparison.cc (scope_diff::report): Do not report added/removed type_decls. 2013-10-24 Dodji Seketeli Fix string representation for variables and methods * src/abg-ir.cc (var_decl::get_pretty_representation): Don't use the pretty representation for the type of the variable; just use its qualified name. (method_type::set_class_type): I wonder what I was thinking when setting the first parameter's type to being the type of the class. Remove this. (function_decl::get_pretty_representation): Use the "method " prefix for methods. Avoid printing the first parameter of methods. Use the qualified name of the parameter type, rather than its pretty representation. * src/abg-writer.cc (write_class_decl): Do not skip the first function parameter when serializing the method. 2013-10-24 Dodji Seketeli Support reporting removed types/decls * include/abg-comparison.h (scope_diff::{removed_types, removed_decls, added_types, added_decls}): New accessor methods declarations. * src/abg-comparison.cc (scope_diff::{removed_types, removed_decls, added_types, added_decls}): New accessor methods definitions. (scope_diff::report): Report removed & added types/decls. 2013-10-24 Dodji Seketeli Fix erratic reporting of changed types & decls in scopes * src/abg-comparison.cc (scope_diff::ensure_lookup_tables_populated): A changed type/decl is not only one that has been both deleted and inserted (as is a type/decl with a given name N has been deleted and a type/decl with that same name N has been inserted), but we must also ensure that both inserted and deleted type/decl are not the same. Otherwise, it might has been a type/decl that has been shuffled around. 2013-10-24 Dodji Seketeli Fix some class & scope diff reports formatting glitchs * src/abg-comparison.cc (class_diff::report): Quote data members. (scope_diff::report): Simplify how we report changed types. Avoid unnecessary vertical spaces. 2013-10-24 Dodji Seketeli Pretty representation for variables and types by default * include/abg-ir.h (var_decl::get_pretty_representation): New method declaration. * src/abg-ir.cc (decl_base::get_pretty_representation): Prefix types with the "type " string. (var_decl::get_pretty_representation): New method definition. 2013-10-24 Dodji Seketeli Re-write middle snakes management in core diff algorithms * include/abg-diff-utils.h (point::set): New overload.. (point::{add, operator<, operator>, operator<=, operator>=}): New methods. (point::operator!=): Constify. (point::operator==): Constify. Cleanup. (point::operator=): Keep emptiness. (class snake): New class definition (d_path_vec::{over_bounds, offset}): New methods. (d_path_vec::check_index_against_bound): Don't take a bound parameter anymore. Use the new over_bound method above. Fix up error reporting. (d_path_vec::d_path_vec): Fix d_path_vec size allocation. (d_path_vec::operator[]): Use the d_path_vec::at method to check all accesses against the bounds. This is slower, but at least we can expect to have something that is more robust. We can remove the bound checking later when we are sure the code has been tested enough. Also use the new offset() method. (d_path_vec::at): Take long long. (ends_of_furthest_d_paths_overlap): Constify input parameters. (end_of_fr_d_path_in_k, end_of_frr_d_path_in_k_plus_delta): Take an instance of the new snake in parameter, rather than a bare end point that wasn't carrying enough information about the snake. Record the snake which consists of up to four points: a begin point, an intermediate point, a diagonal start point and an end point. Return that snake upon successful completion. (compute_middle_snake): Take an instance of snake, rather than the two points that were supposed to represent a snake and with which we were loosing information before. Revisit/simplify the logic of this function; this literally goes forward or in reverse, gets the resulting snake returned by the end_of_fr_d_path_in_k and end_of_frr_d_path_in_k_plus_delta functions, detect if these snakes overlap and just return the current snake. Much simpler. The caller now gets a snake, which has much more information than the previous snake approximation made of just two points. Bonus point, this follows almost to the word, what the paper says. (maybe_record_match_point, find_snake_start_point): Remove these as there are not used by compute_middle_snake anymore. (print_snake, ses_len): Update these to take/handle a snake. (snake_end_points): New declaration. (compute_diff): When we are getting an empty first sequence, this means that we are inserting the second sequence *before* the beginning of the first sequence; keep this information by setting the insertion point index to -1, rather than zero. Update this to get/handle snakes, rather than free points vaguely representing snakes. Now that compute_middle_snake returns real snakes, handle the information we are getting. Basically for edit scripts of length equal to 1, as the snake carries all the necessary information about the non-diagonal edge (as well as the diagonal edges), we (can) now precisely update the current edit script (as well as the longest common sub-sequence). For edit scripts of length greater than 1, better at which points to divide the problem and consequently, at which points to conquer it back -- better following The Paper to the letter. (display_edit_script): Update this for the use of instances of snake. * src/abg-diff-utils.cc (ends_of_furthest_d_paths_overlap): Update for constification of inputs. (snake_end_points): Define new function.

(function_decl_diff::{deleted_parameter_at, inserted_parameter_at, ensure_lookup_tables_populated, function_decl_diff, first_function_decl, second_function_decl, changed_parms, removed_parms, added_parms, length, report}): New member function definitions. * src/abg-hash.cc (function_decl::parameter::hash): Update this to take the index in account. 2013-10-19 Dodji Seketeli Misc style & white space fixes * include/abg-fwd.h (is_global_scope, is_at_global_scope) (is_at_class_scope, is_at_template_scope, is_template_parameter) (is_type, is_var_decl, is_template_parm_composition_type) (is_template_decl, is_function_template_pattern) (add_decl_to_scope, get_global_scope, get_translation_unit): Remove parameter names from declarations. * include/abg-ir.h (decl_base::set_location): Remove useless white space. (struct type_shared_ptr_equal): Fix comment filling. 2013-10-16 Dodji Seketeli Avoid useless hashing during serialization * src/abg-writer.cc (write_context::get_id_for_type): Avoid the useless hashing incurred by the [] operator on the map, when we already have the value we want. 2013-10-16 Dodji Seketeli Add more IR nodes dumping routines * include/abg-fwd.h (dump): Declare 4 overloads for the dumping routines. * include/abg-ir.h (var_decl_sptr): New typedef. * src/abg-writer.cc (dump(const decl_base_sptr)): Add comments.

(type_decl::operator==(const type_base&)): To ease maintenance, re-use the equality operator that takes a decl_base. (scope_type_decl::operator==(const type_base&)): Likewise. (qualified_type_def::operator==(const type_base&)): Likewise. (compare_function_types): New sub-routine to compare function types. It fixes an infinite recursion when comparing two methods of the same class. (function_type::operator==(const type_base&)): Use the new compare_function_types function. (class_decl::operator==(const decl_base&)): Fix a thinko in the first test of the function. Use a dedicated scope for each class section comparison; that way, there won't be any chance to misuse the variables pertaining to a different section. Fix the member function sections; we were mistakenly using the variables for the *data* section there. (class_decl::operator==(const type_base&)): Re-use the operator that takes a decl_base. (class_decl::operator==(const class_decl&)): Don't remove const-ness during the static cast. (class_decl::member_function::operator==(const member_function&)): Do not remove the reference from the static cast. (class_decl::member_class_template::operator==(const member_base&)): Likewise.

(class_tdecl::operator==(const class_tdecl&)): Likewise. * tests/data/test-read-write/test12.xml: Update this because the test now correctly considers two type template parameters at the same index as being equivalent. * tests/data/test-read-write/test13.xml: Likewise. 2013-10-16 Dodji Seketeli On going white space cleanups * include/abg-ir.h: Remove useless white spaces. * src/abg-ir.cc: Likewise. * src/abg-reader.cc: Likewise. * src/abg-writer.cc: Likewise. 2013-10-15 Dodji Seketeli Finish reporting about class_diff * src/abg-comparison.cc (report_num_dels_or_ins): Factorize out the header of each of inserted/deleted parts of the class into this new function.

Changed the type of these to decl_base_sptr (diff::diff): Update for the change above. (diff::{length, report}): New virtual pure methods. (class pointer_diff, reference_diff): New classes declarations. (compute_diff): New overloads for the new classes above. Make the existing overloads take shared_pointers instead of references.

(compute_diff): Change the overload for translation_unit to take a translation_unit_sptr rather than a reference. * tools/bidiff.cc (main): Update this wrt the change of the signature of compute_diff. 2013-10-15 Dodji Seketeli Fix construction of class_decl::member_type * include/abg-ir.h (class_decl::member_type::member_type): Remove inline body from here. * src/abg-ir.cc (class_decl::member_type::member_type): Move implementation here. Also, properly set the name of the the member_type at construction time. 2013-10-15 Dodji Seketeli Few typedef additions to abg-ir.h * include/abg-ir.h (pointer_type_def_sptr) (reference_type_def_sptr): New typedefs. 2013-10-11 Dodji Seketeli Add debugging routines for decl_base_sptr and translation_unit * src/abg-writer.cc (dump): Add two version of this; on for decl_base_sptr, one for translation_unit&. 2013-10-11 Dodji Seketeli Initial implementation of tu diffing & bidiff cmd line program * include/abg-comparison.h (class translation_unit_diff): New type. (compute_diff): Make this take class_decl&, rather than class_decl_sptr. Add new overloads for scope_decl& and translation_unit&.

This makes the descendant operator be the one called when a comparison involves references the parent class. * src/abg-ir.cc: Write the implementation of the above. Remove the useless static_casts from the previous operator== code. 2013-10-10 Dodji Seketeli On going misc white spaces and style fixes * include/abg-ir.h: Add author. Remove many useless white spaces. Add missing end-of-class comments. Move function declaration comments from here to their definition point. * include/abg-fwd.h: Remove useless indentation. Also move doxygen comments to *definition* points in src/abg-ir.cc. * src/abg-ir.cc: Remove many useless white spaces. Move comments from declaration points to here. 2013-10-06 Dodji Seketeli Fix middle snake determination & ses len computation for d == 1 * include/abg-diff-utils.h (compute_middle_snake): After the overlap determination happened, finding the middle snake can require keep on building the current path until the "end". The end meaning reaching the max of D. And that max is (M + N)/2 + 1. In the extreme cases were middle snake was on the very last step (M + N) + 1, we were not finding the middle snake. Fix this. (compute_diff): When d == 1 and the first edge on the edit graph is a non-diagonal edge and when a_base != a_begin, we were failing to properly initialize x,y to find that non-diagonal edge. Also we were failing to correctly compute the size of the sequence. Fix these. * tests/test-core-diff.cc: Add a new regression test for the two cases above. * tests/data/test-core-diff/report7.txt: New reference data for the new regression test. 2013-10-05 Dodji Seketeli Initial un-debugged implementation of scope diffing * include/abg-comparison.h (class scope_diff): New type. (compute_diff(scope_decl_sptr, scope_decl_sptr, scope_diff)): New declaration. (report_changes): New declaration. * src/abg-comparison.cc (struct scope_diff::priv): Define. (scope_diff::{clear_lookup_tables, lookup_tables_empty, ensure_lookup_tables_populated, scope_diff, member_changes, deleted_member_at, inserted_member_at, changed_types, changed_decls}): Define these new member functions.

(scope_decl::{operator==, traverse}): Adjust for using vectors to store scope members now, rather than lists. (scope_decl::{declarations, scopes}): Make these types be vector. This makes the members of a scopes be vector, rather than lists. This enables them to be diffed. 2013-10-05 Dodji Seketeli Simplify & cleanup compute_diff core api * include/abg-diff-utils.h (insertion::inserted_): Changed the type of this from vector to vector. (insertion::{insertion, inserted_indexes}): Adjust. (compute_diff): Add two new simpler overloads. Implement them in term of the former more complex overload.

(class type_base): Add a _sptr typedef and end of class comment. * src/abg-ir.cc (operator==(class_decl_sptr, class_decl_sptr)): Fix comment. 2013-10-04 Dodji Seketeli Un-debugged initial implementation of class diffing. * include/abg-ir.h (decl_base::get_qualified_name): New declaration. (class_decl::{base_specs, member_types, data_members, member_functions, member_function_templates, member_class_templates}): Make all these containers be vectors, rather than list. This makes these containers (like class_decl::base_specs, class_decl::member_types, etc) be suitable to be used by the core diffing algorithms to diff their content. (operator==(class_decl_sptr, class_decl_sptr)) (operator==(class_decl::member_type_sptr, class_decl::member_type_sptr)) (operator==(class_decl::base_spec_sptr, class_decl::base_spec_sptr)) (operator==(class_decl::data_member_sptr, class_decl::data_member_sptr)) (operator==(class_decl::member_function_sptr, class_decl::member_function_sptr)) (operator==(class_decl::member_function_template_sptr, class_decl::member_function_template_sptr)) (operator==(class_decl::member_class_template_sptr, class_decl::member_class_template_sptr)): Declare these new equality operators. These are to be used by the core diffing algorithms when comparing two vectors of shared pointers of members of class_decls. * src/abg-ir.cc (decl_base::get_qualified_name): Define. (class_decl::class_decl, class_decl::operator==(class_decl&)): Adjust for the containers type change to a vector.

(class_decl_diff::{first_class_decl, second_class_decl}) (report_changes): New declarations. * src/abg-comparison.cc (class_decl_diff::class_decl_diff): Update as per the declaration. (class_decl_diff::{first_class_decl, second_class_decl}): Define as per the declaration. (compute_diff): Initial implementation for this. (report_changes): Define. 2013-10-04 Dodji Seketeli Change the diff::changes_type back to just edit_script * include/abg-comparison.h (diff::changes_type): Remove this typedef. (class_decl_diff::data_members_changes): Rename class_decl_diff::data_member_changes into this. (class_decl_diff::member_fn_tmpls_changes): Renamed class_decl_diff::member_fn_tmpl_changes into this.

(class_decl_diff::{base_changes, member_types_changes, data_members_changes, member_fns_changes, member_fn_tmpls_changes, member_fn_tmpls_changes, member_class_tmpls_changes}): Adjust these definitions for the above. 2013-10-04 Dodji Seketeli Misc white space, style and comment fixes * include/abg-ir.h: Lots of useless white space removals and comments adding. (class class_decl::member_base): Fix comment. * src/abg-hash.cc: Lots of useless white space removals too. * src/abg-ir.cc: Remove useless white space too. 2013-10-04 Dodji Seketeli Fix middle snake determination * include/abg-diff-utils.h (point::{operator!=,operator==}): New operators. (end_of_fr_d_path_in_k, end_of_frr_d_path_in_k_plus_delta): Allow the initial point (-1,-1) that is not a point addressing elements of the input sequences, but that is the starting point of the forward paths and the ending point of reverse paths in the "Linear Refinement" of the algorithm. (is_match_point, maybe_record_match_point) (find_snake_start_point): New functions. (find_last_snake_in_path): Remove this. It's not used anymore. (compute_middle_snake): Allow checking for overlapping paths even on points that are outside of the edit graph boundaries. Once the overlap is detected, if a non-empty snake has been seen already, report it as the middle snake. Otherwise, keep building the path until the end and report the last snake encountered as the middle snake. Add comments. (compute_diff): For the d == 1 case, fix the logic of the finding the non-diagonal edge. Fix typos. Add comments. (display_edit_script): Fix report glitches. * tests/data/test-core-diff/report3.txt: Update as per the report glitch above. * tests/data/test-core-diff/report4.txt: Likewise. * tests/data/test-core-diff/report5.txt: Likewise. * tests/data/test-core-diff/report6.txt: New reference report for a new test. * tests/test-core-diff.cc: Add a new test for negative delta. 2013-10-03 Dodji Seketeli Initial regression test facility for core diff algorithms * tests/data/test-core-diff/report0.txt: New test reference data. * tests/data/test-core-diff/report1.txt: Likewise. * tests/data/test-core-diff/report2.txt: Likewise. * tests/data/test-core-diff/report3.txt: Likewise. * tests/data/test-core-diff/report4.txt: Likewise. * tests/data/test-core-diff/report5.txt: Likewise. * tests/test-core-diff.cc: New regression test program. * tests/Makefile.am: Add these new files to the build system. 2013-10-02 Dodji Seketeli Initial command line testing facility for core diff algorithms * tests/test-diff2.cc: New command line testing facility. * tests/Makefile.am: Add this to the build system. 2013-10-02 Dodji Seketeli Fix core diff algorithms for negative deltas * diff2.h (point::point): New copy constructor.

(end_of_fr_d_path_in_k, ): Return a bool when the end of furthest reaching past found is within the bounds of the edit graph. Add comments. (end_of_frr_d_path_in_k_plus_delta): Likewise. Also, delta can be negative; support that. Do not cross the boundaries of the edit graph when following a diagonal edge. (find_last_snake_in_path): New function. (compute_middle_snake): Make forward/reverse d_path_vec be big enough to hold paths for M+N differences. Normally M+N/2 should be enough, but we were getting weird out of bound errors. Let's handle it this way for now. Do not require that we check for overlap only when we are on a diagonal edge. Once we detected an overlap, use the new find_last_snake_in_path to find the boundaries of the snake. (ses_len): Delta can be negative. (display_edit): Small minor English nit. 2013-09-28 Dodji Seketeli Lay down the foundations of computing the diff between two class_decl * include/abg-diff-utils.h: New file. * src/abg-diff-utils.cc: Likewise. Implement the code diffing algorithms from Eugene Myers. * include/abg-comparison.h: New file. First short at defining the basic APIs to compute the diff of two classes. * src/abg-comparison.cc: New file. Start the implementation of the above header. 2013-09-26 Dodji Seketeli Prepare node visitors to be usable on things other than IR nodes * include/abg-fwd.h (node_visitor_base): Renamed ir_node_visitor into this. * include/abg-traverse.h (struct node_visitor_base): New base for the visitors. (struct traversable_base): Update comments. (traversable_base::traverse): Change this into non-pure virtual. Make it take a reference to node_visitor_base, rather than a reference to ir_node_visitor. * src/abg-traverse.cc (traversable_base::traverse): New empty default implementation. * include/abg-ir.h: Make ir_node_visitor inherit from new node_visitor_base. 2013-09-26 Dodji Seketeli Renamed data members from m_something to something_ * src/abg-ir.{cc,h}: Renamed data members from m_something to something_ and update their usage. 2013-08-29 Dodji Seketeli Initial version of an archive manipulation program: biar * tests/test-utils.h (is_dir, ensure_dir_path_created) (ensure_parent_dir_created): Move these directories manipulation utilities from here to ... * tools/abg-tools-utils.h (is_dir, ensure_dir_path_created) (ensure_parent_dir_created): ... here in this new file. (dir_name, base_name): Declare these new functions. * tests/test-utils.cc (is_dir, ensure_dir_path_created) (ensure_parent_dir_created): Likewise, move these to ... * tools/abg-tools-utils.cc (is_dir, ensure_dir_path_created) (ensure_parent_dir_created): ... here in this new file. (dir_name, base_name): Define these. * tools/Makefile.am: New file. Create a new libtoolsutils.la static library with stuff from tools/abg-tools-utils.cc in it. Also create a new 'biar' program with the stuff from the new tools/biar.cc in it. * tools/biar.cc: New file. Contains the code for the new "biar" archive manipulation command line utility. * tests/test-read-write.cc (main): Adjust for the change about ensure_parent_dir_created above. * tests/test-write-read-archive.cc (main): Likewise. * Makefile.am (SUBDIRS): Add the new tools/ sub-directory to the build system. * configure.ac (AC_CONFIG_FILES): Generate tools/Makefile. * tests/Makefile.am: Make libtestutils.la link with the new libtoolsutils.la. Make sure to express the dependencies between libtestutils.la and the binaries that depend on it. Otherwise parallel builds can go awry. 2013-08-29 Dodji Seketeli Define translation_unit{_sptr,s} types in abigail:: * include/abg-corpus.h (abigail::corpus::{translation_unit_sptr, translation_units): Do not define these typedefs here. Rather) (define them ... * include/abg-ir.h (abigail::{translation_units,translation_unit_sptr): ... here. This is because a translation unit can be manipulated independently from an abi corpus. * src/abg-corpus.cc (corpus::get_translation_units): Adjust return type to comply with the change above. 2013-08-29 Dodji Seketeli Fix header inclusion in abg-corpus.h * include/abg-corpus.h: Drop incomplete abg-traverse.h and abg-fwd.h. Use abg-ir.h proper and be done with it. Users of the library will just have to use abg-corpus.h to manipulate and the archives and the IR they contain. 2013-08-29 Dodji Seketeli Add error message to translation_unit::write * src/abg-writer.cc (translation_unit::write): Add an error message to stderr if something ultimately went wrong. 2013-08-29 Dodji Seketeli Rename abigail::corpus::{get_file_path --> get_path} * include/abg-corpus.h (corpus::{get_path, set_path): Renamed corpus::get_file_path and corpus::set_file_path into these as get_path/set_path is what is used elsewhere as well. * src/abg-corpus.cc (corpus::{get_path, set_path}): Likewise. * tests/test-write-read-archive.cc (main): Adjust for the change above. 2013-08-29 Dodji Seketeli Cleanup src/Makefile.am * src/Makefile.am: Fix library naming and remove useless trailing space from directory path. 2013-08-27 Dodji Seketeli Initial writing/reading of an ABI corpus to an archive * configure.ac: Support detection of libzip dependency. Define new DEPS_CFLAGS and DEPS_LIBS variables for use in Makefile.am to refer to the dependency headers and libraries. * doc/website/mainpage.txt: Update this to talk about the new libzip dependency. * include/Makefile.am: Add abg-libzip-utils.h to the build system. * include/abg-corpus.h (corps): Hide abigail::corpus's private behind a pimpl idiom.

Refer to the library and headers dependencies via the new DEPS_LIBS and DEPS_CFLAGS variables. * src/abg-corpus.cc: New file. * src/abg-ir.cc (translation::set_path): New method. * src/abg-libxml-utils.cc (new_reader_from_buffer): Define new function. * src/abg-libzip-utils.cc: New file. * src/abg-reader.cc (translation_unit::read): New overload. * src/abg-writer.cc: Inject the names from the std namespace into the abigail namespace, rather than into abigail::writer. (abigail::translation_unit::write): New overload. This can now use ofstream and the other stuff from std that are injected in the abigail:: namespace. * tests/Makefile.am: Add tests/test-write-read-archive.cc to the build system; use that to build runtestwritereadarchive. Also add the input test data from tests/data/test-write-read-archive/test[0-4].xml. * /tests/data/test-write-read-archive/test[0-4].xml: New test input data files. * tests/test-write-read-archive.cc: New test for this archive write/read support. 2013-08-27 Dodji Seketeli Fix & add missing API documentation * src/abg-ir.cc (location_manager::create_new_location): Fix documentation comment. (translation_unit::translation_unit) (translation_uni::get_global_scope, translation_unit::get_path) (translation_unit::traverse, translation_unit::get_loc_mgr) (translation_unit::is_empty, translation_unit::traverse): Add missing documentation comments. * src/abg-libxml-utils.cc (new_reader_from_file): Fix comment. * src/abg-reader.cc (translation_unit::read): Likewise. 2013-08-27 Dodji Seketeli Remove useless header inclusion * include/abg-traverse.h: Remove useless #include 2013-08-27 Dodji Seketeli Misc white space cleanups * include/abg-corpus.h: Cleanup white spaces. * include/abg-fwd.h: Likewise. * include/abg-ir.h: Likewise. * include/abg-libxml-utils.h: Likewise. * src/abg-config.cc: Likewise. * src/abg-ir.cc: Likewise. * src/abg-reader.cc: Likewise. * src/abg-writer.cc: Likewise. 2013-08-27 Dodji Seketeli Small cleanup in abg-config.cc * src/abg-config.cc: Include auto-generated $(top_builddir)/config.h file. 2013-08-27 Dodji Seketeli Pass absolute paths to the compiler during the build * src/Makefile.am: Pass absolute file paths to the compiler during the build. This helps in e.g in emacs' compilation mode, when the output shows an error reported by GCC's diagnostics, setting point to the error line and hitting 'enter' transports the user to the file location where the error happened; as the file path is nows absolute, emacs can always find it. Otherwise, finding it depends on $PWD and whatnot. * tests/Makefile.am: Likewise. 2013-08-27 Dodji Seketeli Misc cleanups in abg-fwd.h * include/abg-fwd.h: Move location, location_manager and translation_unit in the ir section. Remove stuff that was commented out anyway. 2013-08-27 Dodji Seketeli Move location, location_manager & translation_unit back into abg-ir.h * include/abg-corpus.h: Move location location_manager, translation_unit from here ... * include/abg-ir.h: ... to here. The reason being that these are really constructs of the Internal Representation of the ABI/API of a translation unit. What is left in abg-corpus is really exclusively related to an ABI Corpus, which I see more as a "packaging" construct that abstracts the bundling of several translation units together. Also, I fixed some comments about the location/location_manger types; now a location is made specific to a translation unit; to an abi corpus. A location of a given translation unit has to be decoded by the location manager of that same translation unit. 2013-08-22 Dodji Seketeli Make libxml2 a private dependency wrt pkconfig * libabigail.pc.in: Libxml2 is not exposed to clients so make it be a private dependency. 2013-08-22 Dodji Seketeli White space fix in COMPILING * COMPILING: White space fix. 2013-08-22 Dodji Seketeli Add abg-version.h.in to the source distribution & cleanup * include/Makefile.am: Add abg-version.h.in to the source distribution. * configure.ac: Generate abg-version.h in using the existing AC_CONFIG_FILES macro call. 2013-08-22 Dodji Seketeli Support pkgconfig through a new libabigail.pc file * libabigail.pc.in: New pkgconfig file. * configure.ac: Define the LIBXML2_VERSION variable that is used in the libabigail.pc.in file. Generate the libabigail.pc file from its libabigail.pc.in template. * Makefile.am: Add libabigail.pc.in to the source distribution. Install the generated libabigail.pc to the right destination. 2013-08-21 Dodji Seketeli Tweak the apidoc mainpage * include/abg-fwd.h: Fix link to the project web page and for git check-out. 2013-08-21 Dodji Seketeli Initial website generation-fu using Doxygen * doc/website/mainpage.txt: New file representing the input for the website. * doc/website/libabigail-website.doxy: New file representing the doxygen configuration for the website generation. * doc/api/libabigail.doxy: Output doxygen generation warnings into a file. * doc/Makefile.am: Support generating the website from doxygen.

Add a 'website' target to make the website. 2013-08-21 Dodji Seketeli Fix typo in CONTRIBUTING file * CONTRIBUTING: Fix typo, courtesy of Mark Wielaard. 2013-08-19 Dodji Seketeli Remove autotools-generated files * Makefile.in: Remove this autotools-generated file. I know that people in the GCC-realm like storing these autotools-generated files into the source control system, but I believe in this day and age, this is annoying (to say the least) for the project developers for no good reason. Requiring (the ubiquitous) autoconf for building from source is no big deal today, and typing "autoreconf" is not hard to do, really. And it saves the developers for having to update a bunch of boilerplate automatically generated files into the source control system; this is really unnecessary noise and it is a commonly accepted good practice to avoid doing it these days. To help people who do not know how to handle this, there is a COMPILING file in the source tree that explains how to build the project from sources. * aclocal.m4: Likewise. * configure: Likewise. * include/Makefile.in: Likewise. * src/Makefile.in: Likewise. * doc/Makefile.in: Likewise. * tests/Makefile.in: Likewise. 2013-08-19 Dodji Seketeli Add a new COMPILING file explaining how to build the package * COMPILING: New file. 2013-08-14 Dodji Seketeli Remove name of unused parameter in decl_base::traverse. * src/abg-ir.c (decl_base::traverse): Remove name of unused parameter. 2013-08-14 Dodji Seketeli install headers in $includedir/libabigail * include/Makefile.am: Install headers in $includedir/libabigail 2013-08-14 Dodji Seketeli For usage from within GCC set header path to $includedir/libabigail * abigail.m4: The include path used for compilation goes to $includedir/libabigail. 2013-08-08 Benjamin Kosnik Separate out bits from the ir header. * include/abg-irfwd.h: Move to... * include/abg-fwd.h: ...this. * include/abg-ir.h (traverse_base): Move to... * include/abg-traverse.h: ...here.
