This matches what upload-pack allows, but does restrict some useful cases (e.g., HEAD:foo). We loosened this in 0f544ee, which allows `foo:bar` as long as `foo` is a ref tip. However, that still doesn't allow many useful things, like: 1. Commits accessible from a ref, like `foo^:bar`, which are reachable 2. Arbitrary sha1s, even if they are reachable. We can do a full object-reachability check for these cases, but it can be quite expensive if the client has sent us the sha1 of a tree; we have to visit every sub-tree of every commit in the worst case. Let's instead give site admins an escape hatch, in case they prefer the more liberal behavior. For many sites, the full object database is public anyway (e.g., if you allow dumb walker access), or the site admin may simply decide the security/convenience tradeoff is not worth it. This patch adds a new config option to disable the restrictions added in ee27ca4. It defaults to off, meaning there is no change in behavior by default.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commits ee27ca4 and 0f544ee introduced rules by which git-upload-archive would restrict clients from accessing unreachable objects. However, we never documented those rules anywhere, nor their reason for being. Let's do so now. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

In 23d25e48 (submodule: explicit local branch creation in module_clone) the synopsis of the man page was updated, but the "OPTIONS" section of the man page and the usage string of the git-submodule script still do not mention the '--checkout' option. Fix that by documenting this option in usage string and the "OPTIONS" section of man page too. While at it group the update-mode options into a single set in the usage string.

However, AsciiDoctor (the Ruby implementation of AsciiDoc used to render the http://git-scm.com/ site) does /not/ have this behaviour, and so generates broken links, as can be seen here: http://git-scm.com/docs/git-cvsimport (links to cvs2git & parsecvs) http://git-scm.com/docs/git-filter-branch (link to The BFG) It's worth noting that after this change, the html generated by 'make html' in the git project is identical, and all links still work.

Given that "git add <pathspec>" is to update the index with the state of the named part of the working tree as a whole, it makes it more intuitive, and also makes it possible to simplify the advice we give while marking the paths the user finished resolving conflicts with. We used to say "to record removal as a resolution, remove the path from the working tree and say 'git rm'; for all other cases, edit the path in the working tree and say 'git add'", but we can now say "update the path in the working tree and say 'git add'" instead.

In a recently packed repository, this is fine. A fetch would use the paths only as a heuristic in the delta compression phase, and a fully packed repository should not need to do much delta compression. As time passes, though, we may acquire more objects on top of our large bitmapped pack. If clients fetch frequently, then they never even look at the bitmapped history, and all works as usual. However, a client who has not fetched since the last bitmap repack will have "have" tips in the bitmapped history, but "want" newer objects. The bitmaps themselves degrade gracefully in this circumstance. We manually walk the more recent bits of history, and then use bitmaps when we hit them. But we would also like to perform delta compression between the newer objects and the bitmapped objects (both to delta against what we know the user already has, but also between "new" and "old" objects that the user is fetching). The lack of pathnames makes our delta heuristics much less effective. This patch adds an optional cache of the 32-bit name_hash values to the end of the bitmap file. If present, a reader can use it to match bitmapped and non-bitmapped names during delta compression. Here are perf results for p5310: Test origin/master HEAD^ HEAD ------------------------------------------------------------------------------------------------- 5310.2: repack to disk 36.81(37.82+1.43) 47.70(48.74+1.41) +29.6% 47.75(48.70+1.51) +29.7% 5310.3: simulated clone 30.78(29.70+2.14) 1.08(0.97+0.10) -96.5% 1.07(0.94+0.12) -96.5% 5310.4: simulated fetch 3.16(6.10+0.08) 3.54(10.65+0.06) +12.0% 1.70(3.07+0.06) -46.2% 5310.6: partial bitmap 36.76(43.19+1.81) 6.71(11.25+0.76) -81.7% 4.08(6.26+0.46) -88.9% You can see that the time spent on an incremental fetch goes down, as our delta heuristics are able to do their work. And we save time on the partial bitmap clone for the same reason.

This implies moving old bitmap indexes out of the way if we are repacking a repository that already has them, and moving the newly generated bitmap indexes into the `objects/pack` directory, next to their corresponding packfiles. Since `git repack` is now capable of handling these `.bitmap` files, a normal `git gc` run on a repository that has `pack.writebitmaps` set to true in its config file will generate bitmap indexes as part of the garbage collection process. Alternatively, `git repack` can be called with the `-b` switch to explicitly generate bitmap indexes if you are experimenting and don't want them on all the time.

If bitmap writing is enabled for a given repository (either by calling `pack-objects` with the `--write-bitmap-index` flag or by having `pack.writebitmaps` set to `true` in the config) and pack-objects is writing a packfile that would normally be indexed (i.e. not piping to stdout), we will attempt to write the corresponding bitmap index for the packfile. Bitmap index writing happens after the packfile and its index has been successfully written to disk (`finish_tmp_packfile`). The process is performed in several steps: 1. `bitmap_writer_set_checksum`: this call stores the partial checksum for the packfile being written; the checksum will be written in the resulting bitmap index to verify its integrity 2. `bitmap_writer_build_type_index`: this call uses the array of `struct object_entry` that has just been sorted when writing out the actual packfile index to disk to generate 4 type-index bitmaps (one for each object type). These bitmaps have their nth bit set if the given object is of the bitmap's type. E.g. the nth bit of the Commits bitmap will be 1 if the nth object in the packfile index is a commit. This is a very cheap operation because the bitmap writing code has access to the metadata stored in the `struct object_entry` array, and hence the real type for each object in the packfile. 3. `bitmap_writer_reuse_bitmaps`: if there exists an existing bitmap index for one of the packfiles we're trying to repack, this call will efficiently rebuild the existing bitmaps so they can be reused on the new index. All the existing bitmaps will be stored in a `reuse` hash table, and the commit selection phase will prioritize these when selecting, as they can be written directly to the new index without having to perform a revision walk to fill the bitmap. This can greatly speed up the repack of a repository that already has bitmaps. 4. `bitmap_writer_select_commits`: if bitmap writing is enabled for a given `pack-objects` run, the sequence of commits generated during the Counting Objects phase will be stored in an array. We then use that array to build up the list of selected commits. Writing a bitmap in the index for each object in the repository would be cost-prohibitive, so we use a simple heuristic to pick the commits that will be indexed with bitmaps. The current heuristics are a simplified version of JGit's original implementation. We select a higher density of commits depending on their age: the 100 most recent commits are always selected, after that we pick 1 commit of each 100, and the gap increases as the commits grow older. On top of that, we make sure that every single branch that has not been merged (all the tips that would be required from a clone) gets their own bitmap, and when selecting commits between a gap, we tend to prioritize the commit with the most parents. Do note that there is no right/wrong way to perform commit selection; different selection algorithms will result in different commits being selected, but there's no such thing as "missing a commit". The bitmap walker algorithm implemented in `prepare_bitmap_walk` is able to adapt to missing bitmaps by performing manual walks that complete the bitmap: the ideal selection algorithm, however, would select the commits that are more likely to be used as roots for a walk in the future (e.g. the tips of each branch, and so on) to ensure a bitmap for them is always available. 5. `bitmap_writer_build`: this is the computationally expensive part of bitmap generation. Based on the list of commits that were selected in the previous step, we perform several incremental walks to generate the bitmap for each commit. The walks begin from the oldest commit, and are built up incrementally for each branch. E.g. consider this dag where A, B, C, D, E, F are the selected commits, and a, b, c, e are a chunk of simplified history that will not receive bitmaps. A---a---B--b--C--c--D \ E--e--F We start by building the bitmap for A, using A as the root for a revision walk and marking all the objects that are reachable until the walk is over. Once this bitmap is stored, we reuse the bitmap walker to perform the walk for B, assuming that once we reach A again, the walk will be terminated because A has already been SEEN on the previous walk. This process is repeated for C, and D, but when we try to generate the bitmaps for E, we can reuse neither the current walk nor the bitmap we have generated so far. What we do now is resetting both the walk and clearing the bitmap, and performing the walk from scratch using E as the origin. This new walk, however, does not need to be completed. Once we hit B, we can lookup the bitmap we have already stored for that commit and OR it with the existing bitmap we've composed so far, allowing us to limit the walk early. After all the bitmaps have been generated, another iteration through the list of commits is performed to find the best XOR offsets for compression before writing them to disk. Because of the incremental nature of these bitmaps, XORing one of them with its predecesor results in a minimal "bitmap delta" most of the time. We can write this delta to the on-disk bitmap index, and then re-compose the original bitmaps by XORing them again when loaded. This is a phase very similar to pack-object's `find_delta` (using bitmaps instead of objects, of course), except the heuristics have been greatly simplified: we only check the 10 bitmaps before any given one to find best compressing one. This gives good results in practice, because there is locality in the ordering of the objects (and therefore bitmaps) in the packfile. 6. `bitmap_writer_finish`: the last step in the process is serializing to disk all the bitmap data that has been generated in the two previous steps. The bitmap is written to a tmp file and then moved atomically to its final destination, using the same process as `pack-write.c:write_idx_file`.

Calling `git rev-list --objects --use-bitmap-index [committish]` will perform an object iteration based on a bitmap result instead of actually walking the object graph. These are some example timings for `torvalds/linux` (warm cache, best-of-five): $ time git rev-list --objects master > /dev/null real 0m34.191s user 0m33.904s sys 0m0.268s $ time git rev-list --objects --use-bitmap-index master > /dev/null real 0m1.041s user 0m0.976s sys 0m0.064s Likewise, using `git rev-list --count --use-bitmap-index` will speed up the counting operation by building the resulting bitmap and performing a fast popcount (number of bits set on the bitmap) on the result. Here are some sample timings of different ways to count commits in `torvalds/linux`: $ time git rev-list master | wc -l 399882 real 0m6.524s user 0m6.060s sys 0m3.284s $ time git rev-list --count master 399882 real 0m4.318s user 0m4.236s sys 0m0.076s $ time git rev-list --use-bitmap-index --count master 399882 real 0m0.217s user 0m0.176s sys 0m0.040s This also respects negative refs, so you can use it to count a slice of history: $ time git rev-list --count v3.0..master 144843 real 0m1.971s user 0m1.932s sys 0m0.036s $ time git rev-list --use-bitmap-index --count v3.0..master real 0m0.280s user 0m0.220s sys 0m0.056s Though note that the closer the endpoints, the less it helps. In the traversal case, we have fewer commits to cross, so we take less time. But the bitmap time is dominated by generating the pack revindex, which is constant with respect to the refs given. Note that you cannot yet get a fast --left-right count of a symmetric difference (e.g., "--count --left-right master...topic"). The slow part of that walk actually happens during the merge-base determination when we parse "master...topic". Even though a count does not actually need to know the real merge base (it only needs to take the symmetric difference of the bitmaps), the revision code would require some refactoring to handle this case. Additionally, a `--test-bitmap` flag has been added that will perform the same rev-list manually (i.e. using a normal revwalk) and using bitmaps, and verify that the results are the same. This can be used to exercise the bitmap code, and also to verify that the contents of the .bitmap file are sane.

For a reasonably-packed large repo, the time to fetch and clone is often dominated by the full-object revision walk during the Counting Objects phase. Using bitmaps can reduce the CPU time required on the server (and therefore start sending the actual pack data with less delay). For bitmaps to be used, the following must be true: 1. We must be packing to stdout (as a normal `pack-objects` from `upload-pack` would do). 2. There must be a .bitmap index containing at least one of the "have" objects that the client is asking for. 3. Bitmaps must be enabled (they are enabled by default, but can be disabled by setting `pack.usebitmaps` to false, or by using `--no-use-bitmap-index` on the command-line). If any of these is not true, we fall back to doing a normal walk of the object graph. Here are some sample timings from a full pack of `torvalds/linux` (i.e. something very similar to what would be generated for a clone of the repository) that show the speedup produced by various methods: [existing graph traversal] $ time git pack-objects --all --stdout --no-use-bitmap-index \ </dev/null >/dev/null Counting objects: 3237103, done.

This change clarifies that the example command uses the pickaxe interface and what it is searching for. Signed-off-by: Albert L.

This change explains the difference made by using this option, namely copying instead of hardlinking, and why it may be useful. Signed-off-by: Albert L.
