From 575f3f09e9cae11cce199b1d7716d499aa5984d1 Mon Sep 17 00:00:00 2001 From: Christoph Ostarek Date: Tue, 3 Sep 2024 14:40:23 +0200 Subject: [PATCH] tools: introduce git-change-exec tool This new tool detects if in your git tree changed files (compared to master branch and local-only changed files) and uses this information to run only the specified actions. Here it is used to run pillar's go-tests only if something changed there, same for this tool itself and the get-deps tool.
