NAME
abipkgdiff - compare ABIs of ELF files in software packages
abipkgdiff compares the Application Binary Interfaces (ABI) of the ELF binaries contained in two software
packages. The software package formats currently supported are Deb, RPM, tar archives (either compressed
or not) and plain directories that contain binaries.
For a comprehensive ABI change report that includes changes about function and variable sub-types, the
two input packages must be accompanied with their debug information packages that contain debug
information in DWARF format.
INVOCATION
abipkgdiff [option] <package1> <package2>
OPTIONS
• --help | -h
Display a short help about the command and exit.
• --version | -v
Display the version of the program and exit.
• --debug-info-pkg1 | --d1 <path>
For cases where the debug information for package1 is split out into a separate file, tells
abipkgdiff where to find that separate debug information package.
• --debug-info-pkg2 | --d2 <path>
For cases where the debug information for package2 is split out into a separate file, tells
abipkgdiff where to find that separate debug information package.
• --dso-only
Compare ELF files that are shared libraries, only. Do not compare executable files, for instance.
• --redundant
In the diff reports, do display redundant changes. A redundant change is a change that has been
displayed elsewhere in a given report.
• --no-linkage-name
In the resulting report, do not display the linkage names of the added, removed, or changed
functions or variables.
• --no-added-syms
Do not show the list of functions, variables, or any symbol that was added.
• --no-added-binaries
Do not show the list of binaries that got added to the second package.
Please note that the presence of such added binaries is not considered like an ABI change by this
tool; as such, it doesn't have any impact on the exit code of the tool. It does only have an
informational value. Removed binaries are, however, considered as an ABI change.
• --no-abignore
Do not search the package2 for the presence of suppression files.
• --no-parallel
By default, abipkgdiff will use all the processors it has available to execute concurrently. This
option tells it not to extract packages or run comparisons in parallel.
• --suppressions | --suppr <path-to-suppressions>
Use a suppression specification file located at path-to-suppressions. Note that this option can
appear multiple times on the command line; all the suppression specification files are then taken
into account.
• --no-show-locs
Do not show information about where in the second shared library the respective type was changed.
• --fail-no-dbg
Make the program fail and return a non-zero exit code if couldn't read any of the debug information
that comes from the debug info packages that were given on the command line. If no debug info
package were provided on the command line then this option is not active.
Note that the non-zero exit code returned by the program as a result of this option is the constant
ABIDIFF_ERROR. To know the numerical value of that constant, please refer to the exit code
documentation.
• --keep-tmp-files
Do not erase the temporary directory files that are created during the execution of the tool.
• --verbose
Emit verbose progress messages.
RETURN VALUE
The exit code of the abipkgdiff command is either 0 if the ABI of the binaries compared are equal, or
non-zero if they differ or if the tool encountered an error.
In the later case, the value of the exit code is the same as for the abidiff tool.
