Currently checking that the DPDK ABI\nhas not changed before up-streaming code is not intuitive and the\nprocess is time consuming. Currently contributors must use the\ntest-meson-builds.sh tool, alongside some environmental variables to\ntest their changes. Contributors in many cases are either unaware or\nunable to do this themselves, leading to a potentially serious situation\nwhere they are unknowingly up-streaming code that breaks the ABI. These\nbreakages are caught by Travis, but it would be more efficient if they\nwere caught locally before up-streaming. This patchset introduces changes\nto test-meson-builds.sh, check-abi.sh and adds a new script\ngen-abi-tarballs.sh. The changes to test-meson-builds.sh include UX\nchanges such as adding command line arguments and allowing the use of\nrelative paths. Reduced the number of abi checks to just two, one for both\nx86_64 and ARM, the references for these tests can now be prebuilt and\ndownloaded by test-meson-builds.sh, these changes will allow the tests to\nrun much faster. check-abi.sh is updated to use the prebuilt references.\ngen-abi-tarballs.sh is a new script to generate the prebuilt abi\nreferences used by test-meson-builds.sh, these compressed archives can be\nretrieved from either a local directory or a remote http location.\n\n---\nv5:\n - Patchset has been completely reworked following feedback\n - Patchset is now part of test-meson-builds.sh not the meson build system\n\nv4:\n - Reworked both Python scripts to use more native Python functions\n and modules.\n - Python scripts are now in line with how other Python scripts in\n DPDK are structured.\n\nv3:\n - Fix for bug which now allows meson < 0.48.0 to be used\n - Various coding style changes throughout\n - Minor bug fixes to the various meson.build files\n\nv2: Spelling mistake, corrected spelling of environmental\n\nConor Walsh (4):\n devtools: add generation of compressed abi dump archives\n devtools: abi and UX changes for test-meson-builds.sh\n devtools: change dump file not found to warning in check-abi.sh\n doc: test-meson-builds.sh doc updates\n\n devtools/check-abi.sh | 3 +-\n devtools/gen-abi-tarballs.sh | 48 ++++++++\n devtools/test-meson-builds.sh | 170 ++++++++++++++++++++++------\n doc/guides/contributing/patches.rst | 43 +++++--\n 4 files changed, 220 insertions(+), 44 deletions(-)\n create mode 100755 devtools/gen-abi-tarballs.sh" }
