From ac483e1c2a37180aea9ab985aefde8f236d582a6 Mon Sep 17 00:00:00 2001 From: Michael Pratt Date: Sat, 12 Oct 2024 14:55:04 -0400 Subject: [PATCH] tools/ninja: update to 1.12.1 Update to the most recent stable release, including a new job scheduler and bug fixes. Backport a patch to assist in reworking jobserver support. The original patch for jobserver support requires reworking due to the function CanRunMore() and its usage being significantly changed, including the return becoming an integer instead of a boolean. AcquireToken() must now be used in CanRunMore() in order to quantify how much the job searching loop is able to run at any time, and in order to do so CanRunMore() cannot be a constant function anymore.
