Release Summary:

Resolved issues:

related to #2812

Description of changes:

The restart test in dcQUIC is extremely flaky. At the same time, it is extremely difficult to reproduce it locally. I tried to run it on my Macbook, and run it on my forked repo, but the flakiness never show up. We suspect that Github Action is giving different kinds of MacBook with different architectures which makes the test flaky. For now, to reduce developer pain, I will disable the restart test on MacOS.

Call-outs:

• We primarily notice that the restart test failed with UDP rather TCP. We suspect it is because how different protocols transfer data which leads to success or failure. For this PR, we want to test that theory and only disable the UDP test mentioned by refactor(s2n-quic-dc): disable restart test on MacOS #2839 (comment).
• We shouldn't close the ticket since we can still investigate it later and find out what architecture of MacOS is triggering the flakiness. However, I can downgrade the priority of the ticket to medium/low.

Testing:

CI test: restart test shouldn't run on MacOS.
