That was a very good answer, and it sure sounds like it would work.
However, I failed at implementing it. :( My updated runQueue() function
is:
def runQueue(self):
self.buildProcess = None
count = 1 # current position in the queue
while True:
if self.buildProcess is None:
self.execute(self.cmdQueue[count][2],
self.cmdQueue[count][0],
self.cmdQueue[count][1])
count = count + 1
else:
# I'm not really sure what to put here
I pretty sure I did all of that wrong. ;) Also, how exactly would I
redirect stderr to another place?
