From 86ef0f7a12cd3e68caf6f2bded7a669d0d2d3bf3 Mon Sep 17 00:00:00 2001 From: Ruslan Kuprieiev Date: Wed, 1 Nov 2017 01:49:07 +0200 Subject: [PATCH 01/25] state: add local_state First two parameters are data and cache timestamps, that are saved when dvc modifies them and are used to cheaply detect if something has changed. These .local_state files are ignored by git.
