@seth-priya thank you for contributing the change. Is there a way to add a test for these changes?
I know we do verify if the tars are generated for each architecture/distribution.

[dbwiddis]

Looks good... one fix needed (comments) and one suggestion (constants).

Agree with the question about tests -- I suspect we can at least test the enum determination by manipulating os.arch property.

[dbwiddis]

(Preference) I would really like if at least some these values could be made constants. I see above they correspond to AUDIT_ARCH_XXX, __NR_xxx, etc.

[seth-priya]

thanks @saratvemulapalli @dbwiddis for your feedback, I will work on it and get back soon.

[saratvemulapalli]

Thanks @seth-priya , looks like inherently gradle scripts are testing the expected distributions.

[saratvemulapalli]

@seth-priya could you update CHANGELOG.md and take care of conflicts. We should be good to merge.

[seth-priya]

thanks @saratvemulapalli for the feedback and review comments , agree on the test, addressed the conflict

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-5459-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 d76adf3504e3001a84d53177af8ea36af2cc65c1
# Push it to GitHub
git push --set-upstream origin backport/backport-5459-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-5459-to-2.x.
