From 89be7d2774f81f3d8663999975a6ab64d46bf42e Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Fri, 21 Feb 2025 11:04:23 +0100 Subject: builtin/refs: add '--no-reflog' flag to drop reflogs The "git refs migrate" subcommand converts the backend used for ref storage. It always migrates reflog data as well as refs. Introduce an option to exclude reflogs from migration, allowing them to be discarded when they are unnecessary. This is particularly useful in server-side repositories, where reflogs are typically not expected. However, some repositories may still have them due to historical reasons, such as bugs, misconfigurations, or administrative decisions to enable reflogs for debugging. In such repositories, it would be optimal to drop reflogs during the migration. To address this, introduce the '--no-reflog' flag, which prevents reflog migration. When this flag is used, reflogs from the original reference backend are migrated. Since only the new reference backend remains in the repository, all previous reflogs are permanently discarded.
