From 0153e99780aef64913dfd4c323984874bf688249 Mon Sep 17 00:00:00 2001 From: Jacques Lucke Date: Wed, 7 Jul 2021 11:20:19 +0200 Subject: Geometry Nodes: refactor logging during geometry nodes evaluation Many ui features for geometry nodes need access to information generated during evaluation: * Node warnings. * Attribute search. * Viewer node. * Socket inspection (not in master yet). The way we logged the required information before had some disadvantages: * Viewer node used a completely separate system from node warnings and attribute search. * Most of the context of logged information is lost when e.g. the same node group is used multiple times. * A global lock was needed every time something is logged. This new implementation solves these problems: * All four mentioned ui features use the same underlying logging system. * All context information for logged values is kept intact. * Every thread has its own local logger. The logged informatiton is combined in the end.
