Re: [RESULT] [VOTE] Release Airflow 1.8.0 based on Airflow 1.8.0rc4

I think the skipped task issue mentioned is the same issue described in AIRFLOW-872 . I had a DAG that was consistently hitting it. I believe the skipped task has to have at least one downstream task for this to occur (e.g. LatestOnlyOperator >>

Cutting down on testing time - updated

Hi All, (Welcome to new MacBook Pro that has a send “button” on the touch bar) Jeremiah and I have been looking into optimising the time that is spend on tests. The reason for this was that Travis’ runs are taking more and more time and we are being throttled by travis. As part of that we

Cutting down on testing time

Hi All, Jeremiah and I have been looking into optimising the time that is spend on tests. The reason for this was that Travis’ runs are taking more and more time and we are being throttled by travis. As part of that we enabled color coding of test outcomes and timing of tests. The results kind

Re: [RESULT] [VOTE] Release Airflow 1.8.0 based on Airflow 1.8.0rc4

Not trying to muddy the waters, but the observation of Jeremiah (non deterministic outcomes) might have to do something with #3. I didn’t dive in deeper, yet. == ERROR: test_backfill_examples (tests.BackfillJobTest)

Re: [RESULT] [VOTE] Release Airflow 1.8.0 based on Airflow 1.8.0rc4

Hi Dan, - Backfill indeed runs only one dagrun at the time, see line 1755 of jobs.py. I’ll think about how to fix this over the weekend (I think it was my change that introduced this). Suggestions always welcome. Depending the impact it is a blocker or not. We don’t often use backfills and
