HttpLocust class instance variable not set for all users during setup

[andylin00]

I have a question about how Locust works when specifying multiple users. I run locust --no-web -c 1 -r 1 expecting 2 users spawned at 1 user/sec. I see my HttpLocust-level setup() runs only once, so I assumed there is only 1 Locust instance regardless of number of users even though the output says that 2 ExampleLocusts hatch.

When the example task runs for the first user, everything prints out normally. When the example task runs for the second user, it prints "bye" and then "None" for the table instance variable. Why is my env instance variable saving the value and the table variable not?

Ty in advance.

Code:
`
class ExampleLocust:
task_set = basicTaskset
host = "whatever"
table = None
env = {}

setup() {
    self.env["hello"] = "bye"
    session = boto3.Session()
    dynamodb = session.resource('dynamodb', region_name='us-west-1')
    self.table = dynamodb.Table("exampleTable")

}

class ExampleTaskSet(TaskSequence):
tasks = [exampleTask]

def exampleTask(l):
print(l.locust.env["hello"])
print(l.locust.table)
`

Hello @andvlin .

I have the same problem...

I load users from a file and then save them in a class variable.

1st user is reading it fine, for 2nd user it is empty.

How could you fix this issue?

Thanks and sorry for reviving this closed issue.

I just accepted that setup() in the HttpLocust class will only run once per program execution. I put any user-specific data I need to load in on_start() in the TaskSet / TaskSequence class

Ah...
I've put some user generation code in setup() that saves its data into one main class variable.

But then as soon as the 2nd locust is zero the variable is reset :(

I cannot find a way to make a variable available for all the locusts without modification.

Sorry if I asked the wrong question here, then.

you can use global variables for that most likely @ltpitt
