Release Summary:

Resolved issues:

resolves #2889.

Description of changes:

Instead of checking for the word Copyright in our CI, we should check the phrase Copyright Amazon.com, Inc. or its affiliates. to ensure all files contain Amazon's copyright statement.

Call-outs:

I add the -i option to the command, because case distinction shouldn't affect this check. In fact, we do have at least one file that is using copyright Amazon.com, Inc. or its affiliates:

Testing:

Local test: I removed the Amazon copy right statement in if_xdp.rs. The file would still have the word Copyright at the top, but this test will error:

EC2:path to 2n-quic$ ./scripts/copyright_check 
Copyright Check Failed: /home/ubuntu/workspace/s2n-quic/tools/xdp/s2n-quic-xdp/src/if_xdp.rs
FAILED Copyright Check

Github test: I remove that line on this PR to show that copy right will fail. I then revert the commit to pass the test.
Negative test: for commit: 2ebfdb4, the copyright test failed: https://github.com/aws/s2n-quic/actions/runs/19242825789/job/55009419600?pr=2890.

Positive test: I revert the negative test commit. The new commit is 31cefd6, the copyright test passed: https://github.com/aws/s2n-quic/actions/runs/19242880178/job/55009601767?pr=2890.
