From f89bbbe300dad7bc479db535e7822199f98aca30 Mon Sep 17 00:00:00 2001 From: Benoît Ganne Date: Thu, 4 Mar 2021 14:31:03 +0100 Subject: vlib: refactor trajectory trace debug feature MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.
