Zach Welz’s case sounds like a bug in durable-task. Hard to say without knowing how to reproduce from scratch.
Maxfield Stewart’s case is a duplicate of a well-known open bug about cancelling quiet mode.
ilya s’s case is as designed (
JENKINS-51928). Ditto plytro.
Some other cases are old and likely correspond to behavioral fixes in either timeout or specific nested steps done in the past.
I am closing this issue as it is mixing up a lot of distinct cases and is pretty old. Please do not reopen or add comments. If you have what you consider a bug (after reading
JENKINS-51928) which is reproducible using the latest released versions of all plugins and a current Jenkins LTS, please file a separate (but linked) bug report with complete, minimal, self-contained steps to reproduce the problem from scratch.
