Python setval Examples

Example #1

def load_it(fd, fname):
    logger.debug("Reading: %s" % os.path.split(fname)[1])
    d = load_dict(fname)
    lock.acquire()
    logger.debug("Loading into shared memory: %s" % os.path.split(fname)[1])
    for key, value in d.items():
        shmht.setval(fd, key, value)
    logger.debug("Loaded: %s" % os.path.split(fname)[1])
    lock.release()
