With the recent changes made to stabilize ABI versioning in DPDK, it will
become increasingly important to check patches for ABI compatibility. We
propose adding the ABI compatibility checking to be done as part of the
build.
The advantages to adding the ABI compatibility checking to the build are
two-fold. Firstly, developers can easily check their patches to make sure
they don’t break the ABI without adding any extra steps. Secondly, it
makes the integration into existing CI seamless since there are no extra
scripts to make the CI run. The build will run as usual and if an
incompatibility is detected in the ABI, the build will fail and show the
incompatibility. As an added bonus, enabling the ABI compatibility checks
does not impact the build speed.
The proposed solution works as follows:
1. Generate the ABI dump of the baseline. This can be done with the new
script added in this RFC. This step will only need to be done when the
ABI version changes (so once a year) and can be added to master so it
exists by default. This step can be skipped if the dump files for the
baseline already exist.
2. Build with meson. If there is an ABI incompatibility, the build will
fail and print the incompatibility information.
The patches accompanying this RFC add the ABI dump file generating script,
the meson option required to enable/disable the checks, and the required
meson changes to run the compatibility checks during the build.
Note: This patch set depends on: http://patches.dpdk.org/patch/63765/.
The generated .dump files in this patch set are based on the changes in the
patch "build: fix soname info for 19.11 compatibility". If a decision is
made to use a different format for the sonames, then a v5 of this set will
be required as the .dump files will need to be regenerated.
---
v2:
- Rebased on master for 19.11.
- Moved the experimental syms checks next to the abi checks. This also
removed the dependency on the experimental checks from the shared
build.
- General cleanup.
v3:
- Fixed typo in meson option name in buildtools/meson.build.
v4:
- removed commits 1 and 2 from the patch set since they are not needed
as part of this change
- squash commits 3,4,5,6 into a single commit
- changes meson option from type boolean to feature
- update travis packages
- move check for windows to earlier in build
- add abignore file to suppress experimental functions
- make the directories we store dump files in hidden
- add .dump files for v20.0 ABI to patch set
Kevin Laatz (3):
build: add dump files for v20.0 ABI
build: add abi checks to meson
build: clean up experimental syms check
