From 9b96046b9239589756cde8fbcbafe05ac7ec4611 Mon Sep 17 00:00:00 2001 From: Christian Couder Date: Mon, 2 Oct 2023 18:55:04 +0200 Subject: [PATCH] gc: add `gc.repackFilterTo` config option A previous commit implemented the `gc.repackFilter` config option to specify a filter that should be used by `git gc` when performing repacks. Another previous commit has implemented `git repack --filter-to=` to specify the location of the packfile containing filtered out objects when using a filter. Let's implement the `gc.repackFilterTo` config option to specify that location in the config when `gc.repackFilter` is used. Now when `git gc` will perform a repack with a configured through this option and not empty, the repack process will be passed a corresponding `--filter-to=` argument.
