fedabipkgdiff is a convenient way to compare the ABI of Fedora
packages easily.
The first version of fedabipkgdiff introduced by this patch lets users
perform operations like:
fedabipkgdiff --from fc23 foo-0.1-1.fc23.x86_64.rpm
fedabipkgdiff --from fc23 --to fc24 foo
fedabipkgdiff foo-0.1-1.fc23 foo-0.1-1.fc24
fedabipkgdiff foo-0.1-1.fc23.i686 foo-0.1-1.fc24.i686
fedabipkgdiff --all-subpackages foo-0.1-1.fc23 foo-0.1-1.fc24

* configure.ac: Include the new m4 macros from the autoconf

itertools, urlparse, itertools, shutil, unittest, xdg, koji and
mock. These are necessary for the unit test of
fedabipkgdiff. Generate tests/runtestfedabipkgdiff.py into the

Since libabigail now uses pthreads via the abigail::workers namespace,
the libabigail shared library should link with pthreads. Many to
Michi Henning for raising this.
* src/Makefile.am: Add -pthread to libabigail_la_LDFLAGS.
* tools/Makefile.am: Do not use abinilint_LDFLAGS when it should
be abinilint_LDADD. This one was fixed by Michi Henning.

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.
* doc/manuals/abipkgdiff.rst: Mention the new --no-parallel option.
* tools/Makefile.am: Add -pthread to abipkgdiffs link options.
* tools/abipkgdiff.cc (elf_file_paths_tls_key): New key for the
thread-local vector of ELF filepaths.
(reports_map): A map of the path of the first ELF of a compared pair
and a corpus representing the difference.
(env_map): A map of the corpus difference and a corresponding
environment needed to be kept alive until the diff is reported.
({arg,map}_lock): mutexes to control access to the comparison argument
list and the {reports,env}_map respectively.
(options): Add a new member "parallel" and set it to true in the ctor.
(elf_file): Add a new "size" member and set it in the ctor.
(package descriptor): Arguments passed to extract_package_set.
(compare_args): Arguments passed to the ELF comparison function.
(display_usage): Mention the new "--no-parallel" option.
(pthread_routine_extract_package): A wrapper function around
extract_package to be used in a multi-threaded environment.
({first_second}_package_tree_walker_callback_fn): Add the new ELF file
paths to a thread-specific vector.
(compare): In an overload of compare, verbose output is updated to
always mention the ELF files being compared for each reported stage.
Reporting is no longer done in this function, the resulting difference
is instead passed back to the calling function for reporting in the
main thread, along with a corresponding environment.
(pthread_routine_compare): Accept a pointer to a vector of comparison
arguments. This function is to be called NTHREAD times and share the
vector passed to it with its other invocations. Create the environment
for compare() and store its output in a map if there is a difference.
(create_maps_of_package_content): Allocate memory for a thread local
vector of ELF paths and dispose of it before returning.
(pthread_routine_extract_pkg_and_map_its_content): Renamed from
extract_package_and_map_its_content. Extract the debuginfo as well as
the regular package in this function. Spawn a separate thread for the
extraction of the debug package.
(pthread_join): A function handling thread joining throughout package
extractions.
(prepare_packages): Spawn a thread to extract each set of packages.
(elf_size_is_greater): New comparison function used to order ELF pairs
by size.
(compare): In the overload of compare, pass through the ELF path
vectors and identify pairs to be diffed. Put them in a vector and sort
it by the summed ELF pair size. Spawn comparison threads and safely
check for results in the proper order of the ELF pairs. Report any
differences ASAP and collect the threads after all the reporting is
done, checking their return status.
(parse_command_line): Check for the "--no-parallel" option.

Motive of abipkgdiff tool is to provide abi changes between two
pacakges. Packages can be .rpm, .deb or archives. It also takes
optional debug-info package to support pacakges shipping separate
debug-info.
This commit set-up initial skeleton of abipkgdif tool consisting of
help and usage otions. It ensures pkgdiff tool compiles and run when
libabigail gets compiled as whole. Initially, we will add support for
ABI changes for two rpm packages. Further, support for other pacakging
format can be added.

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

Given an application A that links to a shared library L of version V
denoted L(V) and a subsequent version of that library denoted L(V+P),
the 'abicompat' tool tells the user if L(V+P) is still ABI compatible
with L(V+P). And if it is not, abicompat gives a reports that shows
the differences between L(V) and L(V+P) that makes L(V+P)
ABI-incompatible with A.
The source code of this tool is in the tools/abicompat.cc source
file. To support this new tool, this commit changes the comparison
engine to optionally avoid showing added symbols that were not
referenced by any debug info. It changes the ABI corpus type to allow
the specification of a list of variables and functions symbols to keep
(and drop all other functions and variables which have other symbols
on the floor even before starting to compare the two libraries).
This is how the abicompat tool itself works. It basically compares
L(V) and L(V+P) but it only looks at their exported functions and
variables which symbols are undefined in application A. If the list
of exported and defined variables and functions of L(V) whose symbols
are undefined in A equals that of L(V+P) (including the sub-types of
these variables and functions) A is still compatible with L(V+P).
Otherwise, they might not be compatible depending on the kind of
differences that are found.
