Introduce the concept of environment
There are resources needed by the type system and other artifacts of
libabigail. Today, when the life time of those resources need to be
greater than all of artifacts of Abigail, then said resources are made
global.
But then global resources are not great, if anything because they
complicate the future use of the library in concurrent computing
setups.
As I was in the need to add one resource to be used by the type
system, I decided to sit down and first overhaul how these long lived
resources needed to be handled.
And here comes the concept of "environment". An environment is a
place where one can put resources that need to live longer than all
the other artifacts of the Abigail system. And so, the code that
creates Abigail artifacts needs and environment of for said artifacts
to use. In other words, artifacts now use an environment.
This has interesting and strong implications. We can only compare two
artifacts if they use the same environment. This is quite a strong
requirement.
But then when this requirement is fulfilled, comparing two types
amounts to just comparing two pointer values; hash values for types
can also be cached. Now *that* is great for speed of comparison, is
it not?
This patch introduce the concept environment (which is basically a new
abigail::ir::environment type), removes the global variables and uses
the environment instead. Each ABI artifact (either type or decl) now
has a ::get_environment() member function to get its environment.
This patch also disables the caching of hash values because the
caching must happen only *after* all types have been canonicalized.
We were not respecting that requirement until now, and that introduces
wrong hash values. A subsequent patch is going to re-introduce hash
value caching again, once the infrastructure is in place to set a flag
in the environment (hah!) once type canonicalization is done, and then
later read that flag when some client code requests a hash value, to
know if we should look in the hash value cache or not.
The patch obviously changes the output of numerous regression tests
(if anything b/c it disables hash value caching) so 'make check'
yields regressions. But then, it's only the subsequent patch that
updates the tests.

Handle the life time of the map of canonical types
While working on something else, it turned out that we need to cleanup (de-allocate) the map of canonical types when all the translation units that own types are de-allocated. Otherwise, when new translation units are created later, the types in the canonical types map become unrelated to the types in these new translation units, leading to memory management issues. This patch introduces a "usage watchdog" which detects when no translation unit uses the type system anymore. That usage watchdog is then used in the destructor of the translation_unit type to de-allocate the global data that is logically owned by by the type system. The patch also changes the API to read translation units and corpora in a way that forces users to get a handle on the resulting shared pointer. * include/abg-ir.h (type_base::canonical_types_map_type): Move this typedef into abg-ir.cc and out of the type_base namespace. (type_base::get_canonical_types_map): Likewise. * src/abg-ir.cc (canonical_types_map_type): New typedef that got moved here from type_base::canonical_types_map_type.

(translation_unit::priv::~priv): If the usage watchdog says that the type system is not used, then cleanup the global data logically owned by the type system. * include/abg-dwarf-reader.h (read_corpus_from_elf): Make this return a corpus and set the status by reference using a parameter. * src/abg-dwarf-reader.cc (read_corpus_from_elf): Implement the above. * include/abg-reader.h (read_translation_unit_from_file) (read_translation_unit_from_buffer) (read_translation_unit_from_istream): Remove the overloads that do not return a translation_unit_sptr and that pass it as a parameter. Only keep the overloads that return a translation_unit_sptr, forcing users of the API to own a proper reference on the resulting translation_unit pointer.

Add support for abicompat weak mode
This patch implements the weak mode of abicompat. In this mode, just
the application and the new version of the library are provided. The
types of functions and variables of the library that are consumed by
the application are compared to the types of the functions and
variables expected by the application. The goal is to check if the
types of the declarations consumed by the application and provided by
the library are compatible with what the application expects.
The abicompat first gets the set of symbols undefined in the
application and exported by the library. It then builds the set of
declarations exported by the library that have those symbols. We call
these the set of declarations of the library that are consumed by the
application.
Note that the debug information for the application does not contain
the declarations of the functions/variables whose symbols are
undefined. So we can not just read them to compare them to
declarations exported by the library.
But the *types* of the variables and the *sub-types* of the functions
whose symbols are undefined in the application are present in the
debug information of the application.
So in the weak mode, abicompat compare the *types* of the declarations
consumed by the application as expected by the application (described
by the debug information of the application) with the types of the
declarations exported by the library.
To do this a number of changes were necessary.
The patch builds a representation of all the types found in the
application's debug info. Before that, only the types that are
reachable from exported declarations were represented.
The abidw tool got a new --load-all-types to test this new ability of
loading all types.
The patch also adds support for looking a type, not by name, but by
its internal representation.
In the comparison engine, function_type_diff is introduced to
represent changes between two function types. For this, a new class
type_or_decl_base has been introduced in the IR. It's now the base
class for both decl_base and type_base. And abigail::comparison::diff
now takes two pointers of type_or_decl, not decl_base anymore. So
function_type_diff can take two function_type now; not that a
function_type has no declaration so it doesn't inherit decl_base. A
bunch of changes got made just to adjust to this modification.
A number of fixes were made too, to make this work, like adding
missing comparison operators, removing asserts that too strong, etc..
The patch also adjust the test suite as well as the documentation.

Add --no-architecture option to abidw
For portability of the regression tests of libabigail, we need abidw to avoid emitting information about the architecture of the ELF file it's looking at. This patch thus adds a new --no-architecture option to abidw for that purpose. * tools/abidw.cc (options::write_architecture): New flag. (options::options): Initialize it. (display_usage): Add usage string for the new --no-architecture option. (parse_command): Parse the new --no-architecture command line option. (main): Ignore the architecture name if required by the user. Signed-off-by: Dodji Seketeli <dodji@redhat.com> |

Expose a new libabigail::tools_utils namespace
The utilities present in this namespace were previously living in
tools/abg-tools-utils.h and tools/abg-tools-utils.cc. They were not
exported and were meant to be useful to the tools writting in the
tools/ directory. I realized that these utilities might be useful to
clients of the libabigail library in general so I am making them
available generally. Note that the initial name of the namespace was
libabigail::tools; so renaming it to libabigail::tools_utils required
that I adjust some client code. I have also cleaned up the code,
interfaces and their apidoc a little bit.
* include/abg-tools-utils.h: Moved tools/abg-tools-utils.h in
here. Renamed the namespace tools into tools_utils. Inject
std::ostream, std::istream, std::ifstream, and std::string types
into the tools_utils namespace. Adjust the function declarations
accordingly. Remove the useless dirname() function declaration.
* include/Makefile.am: Add abg-tools-utils.h to the list of
exported headers.
* src/abg-tools-utils.cc: Moved tools/abg-tools-utils.cc in here.
Renamed the namespace tools into tools_utils.
(get_stat): Add apidoc.
(is_dir): Cleanup apidoc.
(dir_name); Cleanup parameter name.
(guess_file_type): Cleanup parameter type.
* src/Makefile.am: Add abg-tools-utils.cc to the list of exported
headers.
* tools/Makefile.am: Do not build the temporary library
libtoolsutils.la anymore as abg-tools-utils.{h,cc} have moved out
of this directory.
* tools/abicompat.cc (parse_command_line, main): Adjust for tools
-> tools_utils namespace change.
* tools/abidiff.cc (parse_command_line, main): Likewise.
* tools/abidw.cc (parse_command_line, main): Likewise.
* tools/abilint.cc (parse_command_line, main): Likewise.
