potiuk opened a new pull request, #38077:
URL: https://github.com/apache/airflow/pull/38077
GitHub actions has strange and complex way of getting conditional jobs. When
you want a job to depend on another job to be running when it is either
successful of fully skipped, you have to write a rather peculiar condition:
```
always() && !failure() && !cancelled()
```
However, it turned out that this condition does not propoagate to to task
that depends on the downstream tasks - for example if "wait-for-ci-images" had
this condition and preceding "build-ci-images" was skipped, the
"wait-for-ci-images" was happily running, but any of the other jobs that
depended on "wait-for-ci-images" has been skipped :(. Simply - skipping tasks
immediately propagates to all the downstream tasks and we cannot easily
mitigate it.
This means that we have to come back to a solution that was implemented
before #38057 - where instead of skipping the whole job, we skip all the steps
in this kob. That makes it a little more clunky but makes the skipping status
not propagate to downstream jobs.
