Modified: jk/native/common jk_lb_worker.c
Log:
This patch changes the behavior by pre-initializing lb_value for each
worker. The selection algorithm searches for the worker with the lowest
lb_value that is not in a failed state. It then increments the lb_value
by the lb_factor. lb_factor is set to the inverse (1/x) of the
lb_factor specified in the config file. When lb_factor in the config
file is 0, this number becomes basically MAX_DOUBLE. That means that
lb_value becomes MAX_DOUBLE, so it will never be selected for any
practical purposes.
