Description

Hello Team,

I am on Oracle-Linux-9.6 upgraded Locust-2.14.2 (on Python-3.9.21) to Locust-2.40.5 (on Python-3.12.9)

On Locust-2.14.2 (on Python-3.9.21) I was using the below conf-file and the web-server is not started (as expected) and the test starts running immediately.

home.conf

headless = true
users = 200
spawn-rate = 1
csv = "stats/home"

After upgrading to Locust-2.40.5 (on Python-3.12.9) the same conf above does not work and the web-server is started (not expected) and nothing proceeds on the console! But changing 'headless = true' to 'headless = yes' works!

As per 2.40.5 version docs @ "https://docs.locust.io/en/stable/configuration.html#locust-conf" 'headless = true' should work right?

Regards
J

Command line

locust -f home.py --config=home.conf --host="https://example.com" --iterations=1

Hmm... I can reproduce the issue. It seems "true" is really not handled ("True" is though).

It may be related to how we handle arguments in locust-cloud, or it is a bug in configargparse. We're making a few updates to locust-cloud in the coming months. We'll try to fix it then!

Or maybe you can have a look @amadeuppereira ?
