From a3eca5844526fd6111e7a1e8bdfa9813673a6f23 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Thu, 16 Dec 2021 16:13:42 +0000 Subject: sparse-checkout: refuse to add to bad patterns When in cone mode sparse-checkout, it is unclear how 'git sparse-checkout add ...' should behave if the existing sparse-checkout file does not match the cone mode patterns. Change the behavior to fail with an error message about the existing patterns. Also, all cone mode patterns start with a '/' character, so add that restriction. This is necessary for our example test 'cone mode: warn on bad pattern', but also requires modifying the example sparse-checkout file we use to test the warnings related to recognizing cone mode patterns. This error checking would cause a failure further down the test script because of a test that adds non-cone mode patterns without cleaning them up. Perform that cleanup as part of the test now.
