2015-06-22parse-options: move unsigned long option parsing out of pack-objects.cCharles Bailey
The unsigned long option parsing (including 'k'/'m'/'g' suffix parsing) is more widely applicable. Add support for OPT_MAGNITUDE to parse-options.h and change pack-objects.c use this support. The error behavior on parse errors follows that of OPT_INTEGER. The name of the option that failed to parse is reported with a brief message describing the expect format for the option argument and then the full usage message for the command invoked. This differs from the previous behavior for OPT_ULONG used in pack-objects for --max-pack-size and --window-memory which used to display the value supplied in the error message and did not display the full usage message.

2015-05-25each_ref_fn: change to take an object_id parameterMichael Haggerty
Change typedef each_ref_fn to take a "const struct object_id *oid" parameter instead of "const unsigned char *sha1". To aid this transition, implement an adapter that can be used to wrap old-style functions matching the old typedef, which is now called "each_ref_sha1_fn"), and make such functions callable via the new interface. This requires the old function and its cb_data to be wrapped in a "struct each_ref_fn_sha1_adapter", and that object to be used as the cb_data for an adapter function, each_ref_fn_adapter(). This is an enormous diff, but most of it consists of simple, mechanical changes to the sites that call any of the "for_each_ref" family of functions. Subsequent to this change, the call sites can be rewritten one by one to use the new interface. Signed-off-by: Michael Haggerty <> Signed-off-by: brian m. carlson <> Signed-off-by: Junio C Hamano <>

* jk/sha1-file-reduce-useless-warnings: sha1_file: squelch "packfile cannot be accessed" warnings
2015-03-31sha1_file: squelch "packfile cannot be accessed" warningsJeff King
When we find an object in a packfile index, we make sure we can still open the packfile itself (or that it is already open), as it might have been deleted by a simultaneous repack. If we can't access the packfile, we print a warning for the user and tell the caller that we don't have the object (we can then look in other packfiles, or find a loose version, before giving up). The warning we print to the user isn't really accomplishing anything, and it is potentially confusing to users. In the normal case, it is complete noise; we find the object elsewhere, and the user does not have to care that we racily saw a packfile index that became stale. It didn't affect the operation at all. A possibly more interesting case is when we later can't find the object, and report failure to the user. In this case the warning could be considered a clue toward that ultimate failure. But it's not really a useful clue in practice. We wouldn't even print it consistently (since we are racing with another process, we might not even see the .idx file, or we might win the race and open the packfile, completing the operation). This patch drops the warning entirely (not only from the fill_pack_entry site, but also from an identical use in pack-objects). If we did find the warning interesting in the error case, we could stuff it away and reveal it to the user when we later die() due to the broken object. But that complexity just isn't worth it.

2014-12-29pack-objects: use --objects-edge-aggressive for shallow reposbrian m. carlson
When fetching into or pushing from a shallow repository, we want to aggressively mark edges as uninteresting, since this decreases the pack size. However, aggressively marking edges can negatively affect performance on large non-shallow repositories with lots of refs. Teach pack-objects a --shallow option to indicate that we're pushing from or fetching into a shallow repository. Use --objects-edge-aggressive only for shallow repositories and otherwise use --objects-edge, which performs better in the general case. Update the callers to pass the --shallow option when they are dealing with a shallow repository. Signed-off-by: brian m. carlson <> Signed-off-by: Junio C Hamano <>

In commit fbd4a70 (list-objects: mark more commits as edges in mark_edges_uninteresting - 2013-08-16), we marked an increasing number of edges uninteresting. This change, and the subsequent change to make this conditional on --objects-edge, are used by --thin to make much smaller packs for shallow clones. Unfortunately, they cause a significant performance regression when pushing non-shallow clones with lots of refs (23.322 seconds vs. 4.785 seconds with 22400 refs). Add an option to git rev-list, --objects-edge-aggressive, that preserves this more aggressive behavior, while leaving --objects-edge to provide more performant behavior. Preserve the current behavior for the moment by using the aggressive option. Signed-off-by: brian m. carlson <> Signed-off-by: Junio C Hamano <>

2014-10-19pack-objects: turn off bitmaps when we split packsJeff King
If a pack.packSizeLimit is set, we may split the pack data across multiple packfiles. This means we cannot generate .bitmap files, as they require that all of the reachable objects are in the same pack. We check that condition when we are generating the list of objects to pack (and disable bitmaps if we are not packing everything), but we forgot to update it when we notice that we needed to split (which doesn't happen until the actual write phase). The resulting bitmaps are quite bogus (they mention entries that do not exist in the pack!) and can cause a fetch or push to send insufficient objects.

2014-10-19pack-objects: double-check options before discarding objectsJeff King
When we are given an expiration time like --unpack-unreachable=2.weeks.ago, we avoid writing out old, unreachable loose objects entirely, under the assumption that running "prune" would simply delete them immediately anyway. However, this is only valid if we computed the same set of reachable objects as prune would. In practice, this is the case, because only git-repack uses the --unpack-unreachable option with an expiration, and it always feeds as many objects into the pack as possible. But we can double-check at runtime just to be sure. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2014-10-19repack: pack objects mentioned by the indexJeff King
When we pack all objects, we use only the objects reachable from references and reflogs. This misses any objects which are reachable from the index, but not yet referenced. By itself this isn't a big deal; the objects can remain loose until they are actually used in a commit. However, it does create a problem when we drop packed but unreachable objects. We try to optimize out the writing of objects that we will immediately prune, which means we must follow the same rules as prune in determining what is reachable. And prune uses the index for this purpose. This is rather uncommon in practice, as objects in the index would not usually have been packed in the first place. But it could happen in a sequence like: 1. You make a commit on a branch that references blob X. 2. You repack, moving X into the pack. 3. You delete the branch (and its reflog), so that X is unreferenced. 4. You "git add" blob X so that it is now referenced only by the index. 5. You repack again with git-gc. The pack-objects we invoke will see that X is neither referenced nor recent and not bother loosening it. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>

2014-10-16pack-objects: match prune logic for discarding objectsJeff King
A recent commit taught git-prune to keep non-recent objects that are reachable from recent ones. However, pack-objects, when loosening unreachable objects, tries to optimize out the write in the case that the object will be immediately pruned. It now gets this wrong, since its rule does not reflect the new prune code (and this can be seen by running t6501 with a strategically placed repack). Let's teach pack-objects similar logic.

2014-10-16pack-objects: refactor unpack-unreachable expiration checkJeff King
When we are loosening unreachable packed objects, we do not bother to process objects that would simply be pruned immediately anyway. The "would be pruned" check is a simple comparison, but is about to get more complicated. Let's pull it out into a separate function. Note that this is slightly less efficient than the original, which avoided even opening old packs, since no object in them could pass the current check, which cares only about the pack mtime. But the new rules will depend on the exact object, so we need to perform the check even for old packs. Note also that we fix a minor buglet when the pack mtime is exactly the same as the expiration time. The prune code considers that worth pruning, whereas our check here considered it worth keeping. This wasn't a big deal. Besides being unlikely to happen, the result was simply that the object was loosened and then pruned, missing the optimization. Still, we can easily fix it while we are here.

2014-08-12pack-objects: turn off bitmaps when we see --shallow linesJeff King
Reachability bitmaps do not work with shallow operations, because they cache a view of the object reachability that represents the true objects. Whereas a shallow repository (or a shallow operation in a repository) is inherently cutting off the object graph with a graft. We explicitly disallow the use of bitmaps in shallow repositories by checking is_repository_shallow(), and we should continue to do that. However, we also want to disallow bitmaps when we are serving a fetch to a shallow client, since we momentarily take on their grafted view of the world. It used to be enough to call is_repository_shallow at the start of pack-objects. Upload-pack wrote the other side's shallow state to a temporary file and pointed the whole pack-objects process at this state with "git --shallow-file", and from the perspective of pack-objects, we really were in a shallow repo. But since b790e0f (upload-pack: send shallow info over stdin to pack-objects, 2014-03-11), we do it differently: we send --shallow lines to pack-objects over stdin, and it registers them itself. This means that our is_repository_shallow check is way too early (we have not been told about the shallowness yet), and that it is insufficient (calling is_repository_shallow is not enough, as the shallow grafts we register do not change its return value). Instead, we can just turn off bitmaps explicitly when we see these lines. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>

2014-06-10pack-objects: stop respecting pack.writebitmapsJeff King
The handling of the pack.writebitmaps config option originally happened in pack-objects, which is quite low-level. It would make more sense for drivers of pack-objects to read the config, and then manipulate pack-objects with command-line options. Recently, repack learned to do so, making the low-level read of pack.writebitmaps redundant here. Other callers, like upload-pack, would not generally want to write bitmaps anyway. This could be considered a regression for somebody who is driving pack-objects themselves outside of repack and expects the config option to be used. However, such users seem rather unlikely given how new the bitmap code is (and the fact that they would basically be reimplementing repack in the first place). Note that we do not do anything with pack.writeBitmapHashCache here. That option is not about "do we write bimaps", but rather "when we are writing bitmaps, how do we do it?". You would want that to kick in anytime you decide to write them, similar to how pack.indexVersion is used. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>

2014-04-04pack-objects: do not reuse packfiles without --delta-base-offsetJeff King
When we are sending a packfile to a remote, we currently try to reuse a whole chunk of packfile without bothering to look at the individual objects. This can make things like initial clones much lighter on the server, as we can just dump the packfile bytes. However, it's possible that the other side cannot read our packfile verbatim. For example, we may have objects stored as OFS_DELTA, but the client is an antique version of git that only understands REF_DELTA. We negotiate this capability over the fetch protocol. A normal pack-objects run will convert OFS_DELTA into REF_DELTA on the fly, but the "reuse pack" code path never even looks at the objects. This patch disables packfile reuse if the other side is missing any capabilities that we might have used in the on-disk pack. Right now the only one is OFS_DELTA, but we may need to expand in the future (e.g., if packv4 introduces new object types). We could be more thorough and only disable reuse in this case when we actually have an OFS_DELTA to send, but: 1. We almost always will have one, since we prefer OFS_DELTA to REF_DELTA when possible. So this case would almost never come up. 2. Looking through the objects defeats the purpose of the optimization, which is to do as little work as possible to get the bytes to the remote.

2014-03-17pack-objects: turn off bitmaps when skipping objectsJeff King
The pack bitmap format requires that we have a single bit for each object in the pack, and that each object's bitmap represents its complete set of reachable objects. Therefore we have no way to represent the bitmap of an object which references objects outside the pack. We notice this problem while generating the bitmaps, as we try to find the offset of a particular object and realize that we do not have it. In this case we die, and neither the bitmap nor the pack is generated. This is correct, but perhaps a little unfriendly. If you have bitmaps turned on in the config, many repacks will fail which would otherwise succeed. E.g., incremental repacks, repacks with "-l" when you have alternates, ".keep" files. Instead, this patch notices early that we are omitting some objects from the pack and turns off bitmaps (with a warning). Note that this is not strictly correct, as it's possible that the object being omitted is not reachable from any other object in the pack. In practice, this is almost never the case, and there are two advantages to doing it this way: 1. The code is much simpler, as we do not have to cleanly abort the bitmap-generation process midway through. 2. We do not waste time partially generating bitmaps only to find out that some object deep in the history is not being packed. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
2014-03-17pack-objects: show reused packfile objects in "Counting objects"Jeff King
When we are sending a pack for push or fetch, we may reuse a chunk of packfile without even parsing it. The progress meter then looks like this: Reusing existing pack: 3440489, done. Counting objects: 3, done. The first line shows that we are reusing a large chunk of objects, and then we further count any objects not included in the reused portion with an actual traversal. These are all implementation details that the user does not need to care about. Instead, we can show the reused objects in the normal "counting..." progress meter (which will simply go much faster than normal), and then continue to add to it as we traverse.

2014-03-17pack-objects: show progress for reused packfilesJeff King
When the "--all-progress" option is in effect, pack-objects shows a progress report for the "writing" phase. If the repository has bitmaps and we are reusing a packfile, the user sees no progress update until the whole packfile is sent. Since this is typically the bulk of what is being written, it can look like git hangs during this phase, even though the transfer is proceeding. This generally only happens with "git push" from a repository with bitmaps. We do not use "--all-progress" for fetch (since the result is going to index-pack on the client, which takes care of progress reporting). And for regular repacks to disk, we do not reuse packfiles. We already have the progress meter setup during write_reused_pack; we just need to call display_progress whiel we are writing out the pack. The progress meter is attached to our output descriptor, so it automatically handles the throughput measurements. However, we need to update the object count as we go, since that is what feeds the percentage we show. We aren't actually parsing the packfile as we send it, so we have no idea how many objects we have sent; we only know that at the end of N bytes, we will have sent M objects. So we cheat a little and assume each object is M/N bytes (i.e., the mean of the objects we are sending). While this isn't strictly true, it actually produces a more pleasing progress meter for the user, as it moves smoothly and predictably (and nobody really cares about the object count; they care about the percentage, and the object count is a proxy for that). One alternative would be to actually show two progress meters: one for the reused pack, and one for the rest of the objects. That would more closely reflect the data we have (the first would be measured in bytes, and the second measured in objects). But it would also be more complex and annoying to the user; rather than seeing one progress meter counting up to 100%, they would finish one meter, then start another one at zero.
