Description

If you have have a workflow, and it does cylc vip to launch another workflow, from within a ROSE app, the second workflow gets confused as the ROSE variables are passed through.

NOTE: I thought this should go in this repo but happy to be corrected if it should be in the rose repo.

Workaround

Current workaround is to do unset "${!ROSE_@}" before cylc vip to ensure they are unset.

Reproducible Example

rose_app_launch_corruption.tar.gz

Download the above. Check its contents to make sure I'm not doing anything nefarious. Then, run the run.sh in the top level.

The launcher workflow launches the runner workflow. If I look at the log for the only task in runner, this is the job.out:

$ cat cylc-run/runner/log/job/20201010T0000Z/run_stuff/NN/job.out
Workflow : runner
Job : 20201010T0000Z/run_stuff/01 (try 1)
User@Host: username@hostname

2024-12-19T23:54:10Z INFO - started
[INFO] export PATH=.....
[INFO] command: launch.sh
$ cylc validate /home/username/rose_app_launch_corruption/runner
Valid for cylc-8.3.6
$ cylc install /home/username/rose_app_launch_corruption/runner

The run_stuff app should be doing an echo.

$ cat cylc-run/runner/app/run_stuff/rose-app.conf
[command]
default=echo "I am running stuff"

Expected Behaviour

The second workflow should not think it is the first workflow. And the tasks should not think they are the launching workflows task.
