From 4307bdaae4355213efdaa46afc16fed4f53cb754 Mon Sep 17 00:00:00 2001 From: cloudhead Date: Fri, 9 Feb 2024 11:32:57 +0100 Subject: [PATCH] sim: Change a few things in the simulator 1. Simplify latency calculation to be more predictable, otherwise, setting a latency is not super useful. 2. Turn a hard error into a log. It's not worth fixing it now though, as it isn't a problem for the tests. --- radicle-node/src/test/simulator.rs | 27 +++++---------------------- 1 file changed, 5 insertions(+), 22 deletions(-) diff --git a/radicle-node/src/test/simulator.rs b/radicle-node/src/test/simulator.rs index 859d6894..8a2f994c 100644 --- a/radicle-node/src/test/simulator.rs +++ b/radicle-node/src/test/simulator.rs @@ -259,25 +259,7 @@ impl Simulation { self.latencies .get(&(from, to)) .cloned() - .map(|l| { - let mut rng = self.rng.borrow_mut(); - - if l <= MIN_LATENCY { - l - } else { - // Create variance in the latency.
