Resolved issues:

resolves #2302

Description of changes:

We want to update the Cloud Front distribution to use the most up to date CI artifact in S2N-QUIC's doc. Instead of just uploading objects to a folder with the commit hash, I also upload those objects into a new folder called latest. I have changed the Cloud Front Origin Path to use the /latest folder to locate all artifacts.

According to the github context page, event_name shows the event that triggers the workflow to run. So, only when github.event_name is equal to push, a PR commit is pushed into main. We add a check for that to ensure only PR merging to main can trigger artifacts uploaded to S3. Additional event details about push can be found in this doc.

Call-outs:

• We still upload those artifacts to each commit hash, because we still want to track artifacts from each commit hash. Using latest is making the CloudFront update easier.
• We want to keep an eye on each PR that's merged in the future to see if they actually update the latest folder.
• A benefit of this approach is that when a report failed to generate or upload, the README.md's artifacts will just use the previous artifacts. It won't break our existing link.
• We would only upload from local to S3 once. We should then copy from existing S3 buckets to another existing S3 buckets using S3 cp command.
  • I found the S3 bucket that record the CI artifacts from the update to main commit. I have verified that those artifacts are successfully uploaded.

Testing:

• We will need to merge it to see if artifacts got uploaded to S3.
  • Once this is merged, we can track if the S3 bucket latest folder is properly updated.
  • This behavior is verified to be correct after merging in doc: automatically update CI artifacts #2606 (comment).
• I pushed an empty commit at 04:25 11 Apr 2025 PT. We can see if the bucket got updated at the time to verify that this change will not update the bucket for each PR push.
  • I can verify that the /latest folder is not updated when this PR pushes another commit.
