[dpdk-dev] [PATCH v5 0/4] devtools: abi breakage checks

[Conor Walsh]

This patchset will help developers discover abi breakages more easily
before upstreaming their code. Currently checking that the DPDK ABI
has not changed before up-streaming code is not intuitive and the
process is time consuming. Currently contributors must use the
test-meson-builds.sh tool, alongside some environmental variables to
test their changes. Contributors in many cases are either unaware or
unable to do this themselves, leading to a potentially serious situation
where they are unknowingly up-streaming code that breaks the ABI. These
breakages are caught by Travis, but it would be more efficient if they
were caught locally before up-streaming. This patchset introduces changes
to test-meson-builds.sh, check-abi.sh and adds a new script
gen-abi-tarballs.sh. The changes to test-meson-builds.sh include UX
changes such as adding command line arguments and allowing the use of
relative paths. Reduced the number of abi checks to just two, one for both
x86_64 and ARM, the references for these tests can now be prebuilt and
downloaded by test-meson-builds.sh, these changes will allow the tests to
run much faster. check-abi.sh is updated to use the prebuilt references.
gen-abi-tarballs.sh is a new script to generate the prebuilt abi
references used by test-meson-builds.sh, these compressed archives can be
retrieved from either a local directory or a remote http location.

v5:
 - Patchset has been completely reworked following feedback
 - Patchset is now part of test-meson-builds.sh not the meson build system

v4:
 - Reworked both Python scripts to use more native Python functions
   and modules.
 - Python scripts are now in line with how other Python scripts in
   DPDK are structured.

v3:
 - Fix for bug which now allows meson < 0.48.0 to be used
 - Various coding style changes throughout
 - Minor bug fixes to the various meson.build files

v2: Spelling mistake, corrected spelling of environmental
