Empty Selector

The mach try empty subcommand is very simple, it won’t schedule any additional tasks. You’ll still see lint tasks and python-unittest tasks if applicable, this is due to a configuration option in taskcluster.

Other than those, your try run will be empty. You can use treeherder’s Add new jobs feature to selectively add additional tasks after the fact.


To use Add new jobs you’ll need to be logged in and have commit access level 1, just as if you were pushing to try.

To do this:

  1. Click the drop-down arrow at the top right of your commit.

  2. Select Add new jobs (it may take a couple seconds to load).

  3. Choose your desired tasks by clicking them one at a time.

  4. At the top of your commit, select Trigger New Jobs.
