Run results show tasks action ratio may be incomprehensible。

[zhu-xiangtao]

Description of issue

In Locust tasks class，define some specific tasks（just use ‘seq_task’ decorate， not use 'task' decorate），also use 'tasks' attribute associate these specific tasks，run results show tasks action ratio may be incomprehensible。

Environment settings

• OS: Win10
• Python version: Python 2.7
• Locust version: 0.11.0

Steps to reproduce (for bug reports)

Locust tasks class as below:

class WebsiteTasks(TaskSequence):

def on_start(self):
    print "start hello imooc..."

@seq_task(1)
def hello_imooc(self):
    self.client.get("/imooc")

@seq_task(2)
def hello_imooc_1(self):
    self.client.get("/imooc_1")

@seq_task(3)
def hello_imooc_2(self):
    self.client.get("/imooc_2")

tasks = {hello_imooc:1, hello_imooc_1:4, hello_imooc_2:2}

Locust user class as below:

class WebsiteUser(HttpLocust):
"""test"""
task_set = WebsiteTasks
host = "http://www.imooc.com"

run in window cmd as below:

locust -f demo.py --logfile=111.log

In web use 1 uses and 1 hatch rate, run a moment, I found task 'hello_imooc' 、'hello_imooc_1'、‘helo_imooc_2’ requests ratio about 1:2.375:1.125，I think the raito may be about 1:4:2

In Locust.core.TaskSetMeta.init , I print some information

print "old_tasks: {}".format(new_tasks)
for item in six.itervalues(classDict):
print "item: {}".format(item)
print hasattr(item, "locust_task_weight")
if hasattr(item, "locust_task_weight"):
print "item lociust task weight: {}".format(item.locust_task_weight)
for i in xrange(0, item.locust_task_weight):
new_tasks.append(item)
print new_tasks

    print "new_tasks: {}".format(new_tasks)

In log file:

old tasks list, 'hello_imooc' 、'hello_imooc_1'、‘helo_imooc_2’, raito is 1:4:2

new taks list, every task add one , raito is 2:5:3, as web run result。

In Locust.core.seq_task, if task have no locust_task_weight attribute，will be assignment default value 1

def seq_task(order):
def decorator_func(func):
func.locust_task_order = order
if not hasattr(func, 'locust_task_weight'):
func.locust_task_weight = 1
return func

return decorator_func

I just think the weight raito should be make clear。
thanks

can you be much more clear? I really have no idea what this issue report is about.
