This fixes a regression introduced inac6d45d11f(commit-graph: move slab-clearing to close_commit_graph(), 2023-10-03), in which running: git -c fetch.writeCommitGraph=true fetch --recurse-submodules multiple times in a freshly cloned repository causes a segfault. What happens in the second (and subsequent) runs is this: 1. We make a "struct commit" for any ref tips which we're storing (even if we already have them, they still go into FETCH_HEAD). Because the first run will have created a commit graph, we'll find those commits in the graph. The commit struct is therefore created with a NULL "maybe_tree" entry, because we can load its oid from the graph later. But to do that we need to remember that we got the commit from the graph, which is recorded in a global commit_graph_data_slab object. 2. Because we're using --recurse-submodules, we'll try to fetch each of the possible submodules. That implies creating a separate "struct repository" in-process for each submodule, which will require a later call to repo_clear(). The call to repo_clear() calls raw_object_store_clear(), which in turn calls close_object_store(), which in turn calls close_commit_graph(). And the latter frees the commit graph data slab. 3. Later, when trying to write out a new commit graph, we'll ask for their tree oid via get_commit_tree_oid(), which will see that the object is parsed but with a NULL maybe_tree field. We'd then usually pull it from the graph file, but because the slab was cleared, we don't realize that we can do so! We end up returning NULL and segfaulting. (It seems questionable that we'd write a graph entry for such a commit anyway, since we know we already have one. I didn't double-check, but that may simply be another side effect of having cleared the slab). The bug is in step (2) above. We should not be clearing the slab when cleaning up the submodule repository structs. Prior toac6d45d11f, we did not do so because it was done inside a helper function that returned early when it saw NULL. So the behavior change from that commit is that we'll now _always_ clear the slab via repo_clear(), even if the repository being closed did not have a commit graph (and thus would have a NULL commit_graph struct). The most immediate fix is to add in a NULL check in close_commit_graph(), making it a true noop when passed in an object_store with a NULL commit_graph (it's OK to just return early, since the rest of its code is already a noop when passed NULL). That restores the pre-ac6d45d11f behavior. And that's what this patch does, along with a test that exercises it (we already have a test that uses submodules along with fetch.writeCommitGraph, but the bug only triggers when there is a subsequent fetch and when that fetch uses --recurse-submodules). So that fixes the regression in the least-risky way possible. I do think there's some fragility here that we might want to follow up on. We have a global commit_graph_data_slab that contains graph positions, and our global commit structs depend on the that slab remaining valid. But close_commit_graph() is just about closing _one_ object store's graph. So it's dangerous to call that function and clear the slab without also throwing away any "struct commit" we might have parsed that depends on it. Which at first glance seems like a bug we could already trigger. In the situation described here, there is no commit graph in the submodule repository, so our commit graph is NULL (in fact, in our test script there is no submodule repo at all, so we immediately return from repo_init() and call repo_clear() only to free up memory). But what would happen if there was one? Wouldn't we see a non-NULL commit_graph entry, and then clear the global slab anyway? The answer is "no", but for very bizarre reasons. Remember that repo_clear() calls raw_object_store_clear(), which then calls close_object_store() and thus close_commit_graph(). But before it does so, raw_object_store_clear() does something else: it frees the commit graph and sets it to NULL! So by this code path we'll _never_ see a non-NULL commit_graph struct, and thus never clear the slab. So it happens to work out. But it still seems questionable to me that we would clear a global slab (which might still be in use) when closing the commit graph. This clearing comes from957ba814bf(commit-graph: when closing the graph, also release the slab, 2021-09-08), and was fixing a case where we really did need it to be closed (and in that case we presumably call close_object_store() more directly). So I suspect there may still be a bug waiting to happen there, as any object loaded before the call to close_object_store() may be stranded with a bogus maybe_tree entry (and thus looking at it after the call might cause an error). But I'm not sure how to trigger it, nor what the fix should look like (you probably would need to "unparse" any objects pulled from the graph). And so this patch punts on that for now in favor of fixing the recent regression in the most direct way, which should not have any other fallouts.
