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 pack‐ ages 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, con‐ sidered 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 con‐ currently. This option tells it not to extract packages or run comparisons in paral‐ lel. · --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 specifica‐ tion 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 com‐ mand 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. COPYRIGHT 2014, Red Hat, Inc.March 10, 2016 ABIPKGDIFF(1)
