All,
I'm trying to write a class that will acquire a lock before entering a
critical section, and then release it. Does this look like the right
way to go about accomplishing my goal?
try:
grabLock = self.lock.acquire( 0 )
if grabLock:
print 'acquired lock successfully'
else:
print "did *not* obtain lock"
< ** what do I put here? ** >
finally:
if grabLock is True:
<do something "critical" here>
self.lock.release()
print 'released lock'
What should I be doing in the else: statement? If I can't grab the
lock, should I simply try again? Maybe a while loop that keeps trying
until I grab the lock? (I'm not really sure how I'm going to integrate
the 'try' statement with the while loop, though, to solve the problem
of not grabbing the lock)
Thoughts?
