Weekly Reports for Year 2023

Week 545 - 12/23 to 12/29

Small in-between week, mainly worked on side 'could be nice' projects.

  • Misc:
    • Investigated usage of libclang (and its python binding) to extract information from C/C++ source code (immediate idea is to replace the very fragile regexes used to extract messages for UI translations updates). Unfortunately, it needs a ‘full’ build to get a valid AST, so this is a slow process (~10 mins on 1 thread only to process the BKE code… and only to extract units’ display names).
    • Investigated new systematically failing ASAN-builds tests in the buildbot.
    • Created design task to decide where to handle modified IDs depsgraph tagging (#116601).
    • Created .profile repo on personal gitea, to host small intro text, and the weekly reports for 2024 now that wiki is discontinued.
  • BT:
    • Reviewed USD: import scenegraph instances (PR #115076).
    • Reviewed USD: Support armature and shape key export (PR #111931).
    • Investigated #108581 Snow character rig has invalid dependencies, leading to evaluation failures in some cases.
Investigated: 1; Reviewed: 2;

      • Cleanup-code pruning unused liboverride operations during RNA diffing would not always work properly, leading to accumulated invalid operations that could, under certain circumstances, end up severely breaking especially collections/objects hierarchies of liboverrides (784d09a87c, 1c0ffa1e18).
      • Resync Enforce tool would not always work properly with collections of IDs (affecting especially Collections/Objects relationships) (2dfbd653a0).

      • As a second approach to work around issue described above, changes were made to liboverride IDs naming, such that when created, they either get the exact same name as their linked reference, or they get a name that does not collide with any other linked override reference (b9becc47de, e11da03e7a).
      • Various minor fixes and improvements (9889d0ef6f, 5b85248c71, df0d6d0022, 6dd51353dd, 457b26aba3, d2c87c3281).
