== Re-running tasks with custom parameters from Treeherder ==
It is possible to run a task again, with certain types of changes to its run time environment and parameters. This feature is commonly used to enable debug logging, or run a test repeatedly to reproduce test failures.
In treeherder, select the job you want to re-run (Note: it currently only works for [https://searchfox.org/mozilla-central/source/taskcluster/taskgraph/actions/retrigger_mochitest.py#30-31 some jobs]). The details panel should open. Look for the 3 dots icon ("Other job details") and select "Custom actions...".
* Run a test repeatedly
* Run until the test fails
Common problems:
* By default the entire task is re-run, running all the tests in the original task. If repeat/runUntilFailure is specified, it may take a long time to repeat all the tests, and the log file may be huge. Consider using the path: parameter to limit the run to the test(s) of interest.
