This gives a description of the HEAD ref if called. This is used as the refname for the HEAD ref whenever the FILTER_REFS_DETACHED_HEAD option is used. Make it public because we need it to calculate the length of the HEAD refs description in branch.c:calc_maxwidth() when we port branch.c to use ref-filter APIs.

Normally delta depth is quite small, but if there _is_ a pathological case, this is where we would find and fix it, so we should be more careful. We can do it without recursion at all, but there's a little bit of cleverness needed to do so. It's easiest to explain by covering the less-clever strategies first. The obvious thing to try is just keeping our own stack on the heap. Whenever we would recurse, push the new entry onto the stack and loop instead. But this gets tricky; when we see an ACTIVE entry, we need to care if we just pushed it (in which case it's a cycle) or if we just popped it (in which case we dealt with its bases, and no we need to clear the ACTIVE flag and compute its depth). You can hack around that in various ways, like keeping a "just pushed" flag, but the logic gets muddled. However, we can observe that we do all of our pushes first, and then all of our pops afterwards. In other words, we can do this in two passes. First dig down to the base, stopping when we see a cycle, and pushing each item onto our stack. Then pop the stack elements, clearing the ACTIVE flag and computing the depth for each. This works, and is reasonably elegant. However, why do we need the stack for the second pass? We can just walk the delta pointers again. There's one complication. Popping the stack went over our list in reverse, so we could compute the depth of each entry by incrementing the depth of its base, which we will have just computed. To go forward in the second pass, we have to compute the total depth on the way down, and then assign it as we go. This patch implements this final strategy, because it not only keeps the memory off the stack, but it eliminates it entirely. Credit for the cleverness in that approach goes to Michael Haggerty; bugs are mine. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

We don't consider it at all when reusing deltas, which means that packing once with --depth=250, and then again with --depth=50, the second pack may still contain chains larger than 50. This is generally considered a feature, as the results of earlier high-depth repacks are carried forward, used for serving fetches, etc. However, since we started using cross-pack deltas in c9af708b1 (pack-objects: use mru list when iterating over packs, 2016-08-11), we are no longer bounded by the length of an existing delta chain in a single pack. Here's one particular pathological case: a sequence of N packs, each with 2 objects, the base of which is stored as a delta in a previous pack. If we chain all the deltas together, we have a cycle of length N. We break the cycle, but the tip delta is still at depth N-1. This is less unlikely than it might sound. See the included test for a reconstruction based on real-world actions. I ran into such a case in the wild, where a client was rapidly sending packs, and we had accumulated 10,000 before doing a server-side repack. The pack that "git repack" tried to generate had a very deep chain, which caused pack-objects to run out of stack space in the recursive write_one(). This patch bounds the length of delta chains in the output pack based on --depth, regardless of whether they are caused by cross-pack deltas or existed in the input packs. This fixes the problem, but does have two possible downsides: 1. High-depth aggressive repacks followed by "normal" repacks will throw away the high-depth chains. In the long run this is probably OK; investigation showed that high-depth repacks aren't actually beneficial, and we dropped the aggressive depth default to match the normal case in 07e7dbf0d (gc: default aggressive depth to 50, 2016-08-11). 2. If you really do want to store high-depth deltas on disk, they may be discarded and new delta computed when serving a fetch, unless you set pack.depth to match your high-depth size. The implementation uses the existing search for delta cycles. That lets us compute the depth of any node based on the depth of its base, because we know the base is DFS_DONE by the time we look at it (modulo any cycles in the graph, but we know there cannot be any because we break them as we see them). There is some subtlety worth mentioning, though. We record the depth of each object as we compute it. It might seem like we could save the per-object storage space by just keeping track of the depth of our traversal (i.e., have break_delta_chains() report how deep it went). But we may visit an object through multiple delta paths, and on subsequent paths we want to know its depth immediately, without having to walk back down to its final base (doing so would make our graph walk quadratic rather than linear). Likewise, one could try to record the depth not from the base, but from our starting point (i.e., start recursion_depth at 0, and pass "recursion_depth + 1" to each invocation of break_delta_chains()). And then when recursion_depth gets too big, we know that we must cut the delta chain. But that technique is wrong if we do not visit the nodes in topological order. In a chain A->B->C, it if we visit "C", then "B", then "A", we will never recurse deeper than 1 link (because we see at each node that we have already visited it).

The reason is that we know that some hierarchies (like refs/tags) are not meant to change, and that unknown hierarchies might not want reflogs at all (e.g., a hypothetical refs/foo might be meant to change often and drop old history immediately). However, sometimes it is useful to override this decision and simply log for all refs, because the safety and audit trail is more important than the performance implications of keeping the log around. This patch introduces a new "always" mode for the core.logallrefupdates option which will log updates to everything under refs/, regardless where in the hierarchy it is (we still will not log things like ORIG_HEAD and FETCH_HEAD, which are known to be transient).

This keeps the connectivity-only code path close to the regular one, but it also introduces some unnecessary inefficiency. While getting the type of an object is cheap compared to actually opening and parsing the object (as the non-connectivity-only case would do), it's still not free. For reachable non-blob objects, we end up having to parse them later anyway (to see what they point to), making our type lookup here redundant. For unreachable objects, we might never hit them at all in the reachability traversal, making the lookup completely wasted. And in some cases, we might have quite a few unreachable objects (e.g., when alternates are used for shared object storage between repositories, it's normal for there to be objects reachable from other repositories but not the one running fsck). The comment in mark_object_for_connectivity() claims two benefits to getting the type up front: 1. We need to know the types during fsck_walk(). (And not explicitly mentioned, but we also need them when printing the types of broken or dangling commits). We can address this by lazy-loading the types as necessary. Most objects never need this lazy-load at all, because they fall into one of these categories: a. Reachable from our tips, and are coerced into the correct type as we traverse (e.g., a parent link will call lookup_commit(), which converts OBJ_NONE to OBJ_COMMIT). b. Unreachable, but not at the tip of a chunk of unreachable history. We only mention the tips as "dangling", so an unreachable commit which links to hundreds of other objects needs only report the type of the tip commit. 2. It serves as a cross-check that the coercion in (1a) is correct (i.e., we'll complain about a parent link that points to a blob). But we get most of this for free already, because right after coercing, we'll parse any non-blob objects. So we'd notice then if we expected a commit and got a blob. The one exception is when we expect a blob, in which case we never actually read the object contents. So this is a slight weakening, but given that the whole point of --connectivity-only is to sacrifice some data integrity checks for speed, this seems like an acceptable tradeoff. Here are before and after timings for an extreme case with ~5M reachable objects and another ~12M unreachable (it's the torvalds/linux repository on GitHub, connected to shared storage for all of the other kernel forks): [before] $ time git fsck --no-dangling --connectivity-only real 3m4.323s user 1m25.121s sys 1m38.710s [after] $ time git fsck --no-dangling --connectivity-only real 0m51.497s user 0m49.575s sys 0m1.776s Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

But we do so by feeding the result of typename() directly to fprintf(). This is potentially dangerous because typename() can return NULL for some type values (like OBJ_NONE). It's doubtful that this can be triggered in practice with the current code, so this is probably not fixing a bug. But it future-proofs us against modifications that make things like OBJ_NONE more likely (and gives future patches a central point to handle them).

When we're checking the objects given to us by the user on the command line. 2. When we're checking if a reflog entry is valid. This generally follows fsck's mental model that we will have looked at and loaded a "struct object" for each object in the repository. But it misses one case: if another object _mentioned_ an object, but we didn't actually parse it or verify that it exists, it will still have a struct. It's not clear if this is a triggerable bug or not. Certainly the later parts of the reachability check need to be careful of this, and do so by checking the HAS_OBJ flag. But both of these steps happen before we start traversing, so probably we won't have followed any links yet. Still, it's easy enough to be defensive here.
