pytracing's Issues

Output can be truncated

The writer thread is terminated without checking if its finished processing the event queue.

I sent a PR that addresses this: #2

doesn't work with multiple processes

Testing the threading behavior, it seems to work:

from time import sleep
from multiprocessing import Process
from threading import Thread

from pytracing import TraceProfiler
tp = TraceProfiler(output=open('trace.out', 'w'))

def my_func():
    sleep(0.1)

def job():
    for i in range(10):
        my_func()

with tp.traced():
    worker = Thread(target=job)
    worker.start()
    worker.join()

Output:

Changing the one line to worker = Process(target=job) I get very long output that catches the Process being created and joined, but doesn't see anything inside. My current solution is to create a pytracing object for each Process, and then I'm going to try and rename/munge and concatenate the traces:
