Running testmon with xdist fails when there is a new Python dependency

[ajeetdsouza]

What is your setup and what steps did you do?

• Create a Poetry project
• Run pytest -n12 --testmon
• poetry add a new dependency
• Run pytest -n12 --testmon and it breaks

What was the outcome?

When the list of packages changes, testmon tries to execute this line:

pytest-testmon/testmon/db.py

Line 673 in cd109a2

cursor.execute(

But the DB has been created as readonly, since it's running within xdist:

pytest-testmon/testmon/pytest_testmon.py

Line 183 in cd109a2

readonly=get_running_as(config) == "worker",

So the execution fails.

What did you expect instead?

.

What is your operating system and it's version please?

macOS 15.2.
