From ed3272720eb5ac8fca0e555d1f64a145140e69dd Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Fri, 7 Jun 2024 15:33:02 +0200 Subject: update-ref: add support for 'symref-create' command Add 'symref-create' command to the '--stdin' mode 'git-update-ref' to allow creation of symbolic refs in a transaction. The 'symref-create' command takes in a , which the created will point to. Also, support the 'core.prefersymlinkrefs' config, wherein if the config is set and the filesystem supports symlinks, we create the symbolic ref as a symlink. We fallback to creating a regular symref if creating the symlink is unsuccessful.
