When abicompat sees a type defined by the library but not used by the

Sometimes we can see const references in DWARF. But then, a reference
is always const, so that qualified reference is redundant.
Furthermore, having that construct make its way into the internal
representation can cause awkward diagnostics.
The DWARF reader was thus eliding such redundant qualifiers in the
function "maybe_strip_qualification". It was doing so by stripping
the qualifier from the qualified type. So const reference, for
instance, becomes a (non-qualified) reference. In that case, we are
turning a qualified type into a non-qualified one.
But as the accompanying problem report suggests, this can cause issues
during the DWARF parsing. This is because a given Debug Information
Entry (DIE) of qualified type kind can be referenced elsewhere, by
another type. That other type expects that DIE to be a qualified
type. And libabigail's DWARF reader code enforces that. So the
internal representation of a type resulting from a qualified type DIE
must be a qualified type itself.
So the way the function "maybe_strip_qualification" was doing the
redundancy elision was wrong. This patch fixes that by keeping the
type qualified, but introducing a "no-op" qualifier. Actually, the IR
already has that "no-op" qualifier: abigail::ir::qualified_type_def::CV_NONE.
So now "maybe_strip_qualification" just turns the CV_CONST qualifier
into a CV_NONE one when the former is redundant.
Now that the libabigail type system actually *has* types qualified
with this no-op qualifier, we need to handle things like printing the
name of such qualified types. When we are printing the name of the
type for internal reasons (i.e, for type canonicalization purposes) we
need to make a difference between the name of a no-op qualified type
and the name of the underlying type of the qualified type, otherwise,
the canonicalizer wrongly considers the two types as being equal. But
then when we are printing the name of the no-op qualified type for
diagnostics reasons, then the name is the same as the name of its
underlying unqualified type.

Abipkgdiff now attempts to extract packages and compare the resulting
ELF pairs in parallel. First off, a thread is spawned to extract each
package and each debuginfo package. After the ELF files are extracted,
mapped and the threads are successfully collected, the resulting
ELF vectors are traversed to identify existing pairs and a list of
arguments for future comparison is made. This list is then sorted
by size from largest to smallest. Unless --no-parallel is
specified on the command line, MIN(pairs,active_processors) threads
are spawned, sharing a single list of arguments. This list is
processed and a map of (ELF_PATH,DIFF_CORPUS) is created. Meanwhile,
the main thread checks this same map for results in the original order
of the ELF pairs, ensuring sequential output. After all the diffing
and reporting is done, the threads are collected again.

When comparing the ABI of the input ELF binary with that same ABI
saved to abixml and read back again, there can be some minor and
harmless changes that are seen, because libabigail makes some
approximations for performance reasons. For instance, if there are
two types that are equivalent, but have different names (because of
typedefs) then libabigail will consider that they are the same type,
and might save them (to abixml) and read them back (from abixml) in
different order.
That can lead to subtle changes that are reported (and filtered out)
by the command "abidw --abixml".
This patch arranges for abidw --abixml to avoid emitting a report
saying that a filtered out change was detected, as those cases are
considered OK.
The patch also fixes a little issue where abidw would abort because
the user forgot to provide the binary to analyze, on the command line.

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.

This patch adds support for comparing the ABI of binaries contained in
a tar archive.
If the archive is compressed with gzip, bzip2, lzip, lzma or xz, then
abipkgdiff recognizes the usual relevant file extensions and lets the
GNU tar program handle the decompression.
If the archive is not compressed, abipkgdiff recognizes the UStar
(Uniform Standard Tape ARchive) format, even if the archive file name
doesn't end with the .tar extension, and lets the GNU tar program
handle the extraction. If the file ends up with the .tar extension
anyway (even if it's not in the UStar format, abipkgdiff lets the GNU
tar program handle its extraction.
* config.h.in (WITH_TAR): New configuration preprocessor macro.
* configure.ac: Add a new --enable-tar option. It's turned on
automatically if the tar program is found in the PATH. Adjust the

If at configure time the libabigail source tarball detects that
rpm2cpio and cpio are present then it enables the support for rpm
files. Users can explicitly enable or disable that support by passing
--enable-rpm or --disable-rpm to configure.
Similarly if it detects that dpkg is present at configure time then it
enables the support for deb files. Users can explicitly enable or
disable that support by passing --enable-deb or --disable-deb to
configure.
* config.h.in: Define WITH_DEB and WITH_RPM pre-processor macros.
* configure.ac: Add --enable-{rpm,deb} switches. Check for
rpm2cpio and cpio programs, unless --disable-rpm was provided. If
they are found and if --enable-rpm=auto was provided, then
consider that --enable-rpm=yes was provided. In that case, set
the WITH_RPM macro to 1. Otherwise, undefine that macro.
Similarly, check for dpkg unless --disable-deb was provided. If
it's found and if --enable-deb=auto was provided, consider that
--enable-deb=yes was provided. In that case, set the WITH_DEB
macro to 1. Otherwise, undefine that macro. Define the

This patch extracts all packages for a given run of abipkgdiff under

To do this, the patch makes accesses of data members of the 'package'

the path to that parent directory in a way that makes it unique, per
