Internal error: variable time_in_mod not in environment. #4140

Open Thaam opened 8 hours ago

Description

With 2.3.0-rc1 release, I have this error:

2024/09/23 20:40:47 [request.dynamic:2] Failed to obtain a media request: Failure("Internal error: variable time_in_mod not in environment.")

The following script works with version 2.2.5.

It works with 2.3.0-rc1 if I remove the if daytime() line.

Steps to reproduce

I get the error with this script:

daytime = time.predicate("9h-21h")

def get_next_track()
    is_day = ref("")
    if daytime() then is_day := "--day" end
    track = process.read("python3 get_next_track.py #{is_day()}")
    request.create(track)
end

main = request.dynamic(get_next_track)
output(mksafe(main))

But this one works:

daytime = time.predicate("9h-21h")

def get_next_track()
    is_day = ref("")

    track = process.read("python3 get_next_track.py #{is_day()}")
    request.create(track)
end

main = request.dynamic(get_next_track)
output(mksafe(main))

Expected behavior

request.dynamic should get a file to play.

The problem was introduced by #3967.

daytime = time.predicate("9h-21h")

thread.run({print(daytime())})
