Bug 24690 - Support comparing non-reachable types of a binary
This patch adds the ability to compare all types of a binary,
including those types that are not reachable from global functions and
variables.
This implies that for types that are not reachable from public
interfaces, we want compare them against each others directly, without
first comparing global functions/variables and walking the graph of
reachable types from there.
The patch adds the --non-reachable-types option to abidiff and
abipkgdiff, instructing them to also compare types that are
non-reachable from global variables and functions.
Using that option, for instance, here is what the summary of
abipkgdiff now looks like, in the test case attached added by this
patch:
================ changes of 'libflatpak.so.0.10204.0'===============
Functions changes summary: 0 Removed, 0 Changed (16 filtered out), 16 Added functions
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable
Unreachable types summary: 3 removed (2 filtered out), 1 changed (15 filtered out), 3 added (1 filtered out) types
You can see that there is a new summary line which starts with the
string: "Unreachable types summary:"
Then in the body of the report, those unreachable types are reported
separately.
In practise, we want to limit the unreachable types to compare
somehow, otherwise we'll end up comparing all the types of the types
of the binary and that can be huge. So we want to limit the
unreachable type analysis to types that are defined in public headers.
So, for abipkgdiff, one can limit the analysis of non-reachable types
to those defined in public headers by supplying the --devel{1,2}
options that specifies the development packages that contain said
public headers. For abidiff however, you'll want to use the
--headers-dir{1,2} options for that.
The patch comes with appropriate regression tests.

Separate public types of first binary from those of the second
In abidiff when the user uses --headers-dir{1,2}, she implicitly
indicates the public types of the first and the second binary. That
means that any type that is defined in a file that is not located
under the directory tree designated by --headers-dir{1,2} is
considered private and any change involving those private types will
be suppressed.
In practice, what happens is that libabigail constructs a suppression
specification which suppress all types that are defined in files that
are not under the directories located by --headers-dir{1,2}.
abidiff has a problem, though. It uses the same private type
suppressions (derived from --headers-dir1 and --headers-dir2) when
looking at the first binary *and* the second binary. It should rather
only use the private type suppression specifications derived from
--headers-dir1 when looking at the first binary, and use the private
type suppression specifications derived from --headers-dir2 when
looking at the second binary.
This problem leads to some false positives like the one reported at
https://gitlab.gnome.org/GNOME/pango/issues/343#note_397761.
This patch fixes this issue by using the private type suppression
specifications derived from --headers-dir1 only when looking at the
first binary, and using the private type suppression specifications
derived from --headers-dir2 only when looking at the second binary.

specification derived from the --headers-dir1 option only for the first
binary, and similarly, from the --headers-dir2 option only for the
second binary.

Initial support of de-serializing the KMI of a Linux Kernel Tree
With this patch, kmidiff knows how to compare a serialized
corpus_group that represents a Kernel Module Interface (a .kmi file)
against either another serialized .kmi file, or against a kernel tree.
The patch extends the abixml reader to make it parse an
'abi-corpus-group' element. To do that, the patch modifies
read_corpus_from_input to make it be capable of parsing several
'abi-corpus' in a row. That modified function is then used by a new
read_corpus_group_from_input, which is itself used by the new public
entry points read_corpus_group_from_native_xml_file and
read_corpus_group_from_native_xml.
With that read_corpus_group_from_native_xml_file building block
function, the kmidiff program is modified so that it can take either
two directory trees, two .kmi files or one directory tree and one .kmi
file.
* include/abg-libxml-utils.h (advance_to_next_sibling_element):
Declare new function.
* src/abg-libxml-utils.cc (go_to_next_sibling_element_or_stay)

member functions.
(read_translation_unit_from_input): Cleanup logic.
(read_corpus_from_input): Don't assume that the document is
starting with an 'abi-corpus' element. Support the mode where a
caller called the xmlTextReaderExpand function (and so we are
given an expanded xmlNodePtr) and the mode where we need to use
the xmlTextReader API to walk through the 'abi-corpus' element.
Also, if we are building a corpus group, do not clear what used to
be 'per-corpus' data. That data must be shared by all the corpora
of a given abi-corpus-group.

is, compare two FILE_TYPE_XML_CORPUS_GROUP if they are present.

Drop suppressed ABI artifacts from the IR
This patch allows dropping suppressed ABI artifacts from the in-memory
internal representation right during the DWARF or abixml reading.
In practise, this means that abidw and abilint now have a
--suppressions options to give them suppression specifications. If a
suppression specification that has the "drop" property matches an ABI
artifact (type, function or variable) then that artifact is dropped
from the internal representation. This also applies to abidiff.
Note that now, by default, ABI artifacts (types) that are suppressed
due to the --headers-dir{1,2} option of abidiff are now also dropped
from the IR as well. Incidentally, abidw and abilint tools now have a
--header-dir option too.

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. (get_canonical_types_map): Likewise got moved here from type_base::get_canonical_types_map. Made static in the process. (class usage_watchdog): New type. (usage_watchdog_sptr, usage_watchdog_wptr): New typedefs. (get_usage_watchdog, get_usage_watchdog_wptr, ref_usage_watchdog) (maybe_cleanup_type_system_data): New static functions. (translation_unit::priv::usage_watchdog_): Add new data member. (translation_unit::priv::priv): Get a reference on the usage watchdog. (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. That is important to handle the life time of the global data of the type system that need to be cleared when the last translation unit is de-allocated. * src/abg-reader.cc (read_translation_unit_from_input): Make this return a translation_unit_sptr.
