It used to be possible to change the value at runtime indeed. In 2.0
we had to review all the configuration items to decide which ones
should be modifiable or not, because several items lived in a grey
area where we never intended them to be modified at runtime but it
was not actually enforced. For this item in particular it did not
seem very interesting to be able to change the value at runtime, and
making it immutable was slightly better for performance. We can
reconsider, of course!
Not for me - I just got curious when I was poking around the load
balancer policies because I observed weird behaviour with wrandom
being very non-random (certain domains seemingly always ending up on
certain backends).
Curiously enough I found a regession test for this in
regression-tests.dnsdist/test_Routing.py, so..bug or feature?
The tests are checking that we can set the value at configuration
time, not at runtime, or am I missing something?
Ah! I misread the test snippet and thought this was runtime.
Nevermind then.
cheers!
