Environment

Thinkpad T530 16GB 8cores. Ubuntu LTS 18.04 up to date. Anaconda Python 3.7.7, with a venv virtual environment activated.

Latest branches of cylc-flow (9d60d6858113322f607b408fb3ead34b3f98a142) and cylc-uiserver (0eba8f3af77ed3adfb10a2f6510b247beaa1fcdc).

Chromium 84. As Cylc UI was built for production mode, VueDevTools doesn't interfere with the performance tests, as it won't be activated either during the tests. I will use only the browser default development tools and lighthouse. Also disabled uBlock origin for localhost.

See file suite.rc for complex workflow source.

Check out conda/conda, and create a venv. Activate it, and run pip install -e ..

Then create a file test.py with the following contents:

from conda.cli.main import main
main('install', '--dry-run', '--use-index-cache', 'cylc==8.0a2')

Now you should be able to debug it. The --use-index-cache is important to skip downloading the

Used the same technique that I tried on spawn-on-demand (here).

I changed main.py in Cylc UI Server to include near the top
