Release Notes Collection Picks Up Incorrect Text

[npolshakova]

What happened:

Release notes collection automation has resulted in incorrect text and markdown being collected: kubernetes/sig-release#2449 (comment)

You can see examples of this merged in sig-release for 1.30 due to past release notes collection:

• PR 123082
• PR 121413
• PR 122893

Updated examples from 1.29 that are still in the repo after 1.30 was cleaned up:

• Fix stale conntrack flow detection logic kubernetes#119394, release notes here.

What you expected to happen:

This release note should not be collected since it is empty:

@npolshakova thank you for the bug report, are you considering to work on a fix?

@npolshakova thank you for the bug report, are you considering to work on a fix?

I'd be interested, but I'm not super familiar with the code that does the release notes collection. Do you think this is an issue on the krel side here?

[saschagrunert]

@npolshakova I assume it's part of the release notes gathering logic of this repository. We just need a reproducer to see what we can fix.

I think the issue is in the regex in the exclude filter: https://github.com/kubernetes/release/pull/3523/files I'm able to reproduce it, but still need a fix for the regex.
