From efa7ae36c134cc0de6f766c1ab5dfd6b55fab65c Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Sat, 22 Feb 2020 20:17:40 +0000 Subject: [PATCH] init-db: move writing repo version into a function When we perform a clone, we won't know the remote side's hash algorithm until we've read the heads. Consequently, we'll need to rewrite the repository format version and hash algorithm once we know what the remote side has. Move the code that does this into its own function so that we can call it from clone in the future.
