+ if (delete_redundant && repository_format_precious_objects) + die("cannot repack in a precious-objects repo");This message initially threw me off during my cursory reading, but the code tells me that this is only about "repack -d". Unfortunately the users do not get the chance to read the code; perhaps s/cannot repack/& -d/; or something?I agree that would be better. I originally just blocked all use of git-repack, but at the last minute softened it to just "repack -d". I'm not sure if that would actually help anyone in practice. Sure, doing "git repack" without any options is not destructive, but I wonder if anybody actually does it.
Hmph, if you cannot afford to lose objects that are unreachable from your refs (because you know your repository has borrowers) but are suffering from too many packs, wouldn't "repack -a" be the most natural thing to do? Maybe I am biased, but "git gc" is not the first thing that comes to my mind in that situation.
So I think we could squash in the patch below (which also marks the strings for translation). But I'd also be OK with the rule covering all of `git repack`.
OK, will squash it in.

[1] One of my proposed uses for this is to revamp the way we handle shared objects on GitHub servers. Right now objects get pushed to individual forks, and then migrate to a shared repository that is accessed via the alternates mechanism. I would like to move to symlinking the `objects/` directory to write directly into the shared space. But the destruction from accidentally running something like `git gc` in a fork is very high. With this patch, we can bump the forks to the v1 format and mark their objects as precious. ---diff --git a/builtin/prune.c b/builtin/prune.c index fc0c8e8..6a58e75 100644 --- a/builtin/prune.c +++ b/builtin/prune.c@@ -219,7 +219,7 @@ int cmd_prune(int argc, const char **argv, const char *prefix) } if (repository_format_precious_objects) - die("cannot prune in a precious-objects repo"); + die(_("cannot prune in a precious-objects repo")); while (argc--) { unsigned char sha1[20];diff --git a/builtin/repack.c b/builtin/repack.c index 8ae7fe5..3beda2c 100644 --- a/builtin/repack.c +++ b/builtin/repack.c@@ -194,7 +194,7 @@ int cmd_repack(int argc, const char **argv, const char *prefix) git_repack_usage, 0); if (delete_redundant && repository_format_precious_objects) - die("cannot repack in a precious-objects repo"); + die(_("cannot delete packs in a precious-objects repo")); if (pack_kept_objects < 0) pack_kept_objects = write_bitmaps;
