From 47c39c28bc1a0001e4341ae70629adcb10f425cc Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Fri, 10 Nov 2023 11:01:24 +0100 Subject: [PATCH] contrib/subtree: convert subtree type check to use case statement The `subtree_for_commit ()` helper function asserts that the subtree identified by its parameters are either a commit or tree. This is done via the `-o` parameter of test, which is discouraged. Refactor the code to instead use a switch statement over the type. Despite being aligned with our coding guidelines, the resulting code is arguably also easier to read.
