2019-02-12get_oid_with_context(): match prototype and implementationLibravatar Duy Nguyen1-3/+5
The get_oid_with_context() function is declared to return an enum in cache.h, but defined to return an int in sha1-name.c. The compiler notices this on AIX and rejects the build, since d1dd94b308 (Do not print 'dangling' for cat-file in case of ambiguity - 2019-01-17) was merged. Return the correct type from the implementation to fix this. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2019-01-18Do not print 'dangling' for cat-file in case of ambiguityLibravatar David Turner1-28/+30
The return values -1 and -2 from get_oid could mean two different things, depending on whether they were from an enum returned by get_tree_entry_follow_symlinks, or from a different code path. This caused 'dangling' to be printed from a git cat-file in the case of an ambiguous (-2) result. Unify the results of get_oid* and get_tree_entry_follow_symlinks to be one common type, with unambiguous values.

2019-01-14sha1-name.c: remove implicit dependency on the_indexLibravatar Nguyễn Thái Ngọc Duy1-22/+32
This kills the_index dependency in get_oid_with_context() but for get_oid() and friends, they still assume the_repository (which also means the_index). Unfortunately the widespread use of get_oid() will make it hard to make the conversion now. We probably will add repo_get_oid() at some point and limit the use of get_oid() in builtin/ instead of forcing all get_oid() call sites to carry struct repository.

2018-11-13object-store: provide helpers for loose_objects_cacheLibravatar Jeff King1-20/+1
Our object_directory struct has a loose objects cache that all users of the struct can see. But the only one that knows how to load the cache is find_short_object_filename(). Let's extract that logic in to a reusable function. While we're at it, let's also reset the cache when we re-read the object directories. This shouldn't have an impact on performance, as re-reads are meant to be rare (and are already expensive, so we avoid them with things like OBJECT_INFO_QUICK). Since the cache is already meant to be an approximation, it's tempting to skip even this bit of safety. But it's necessary to allow more code to use it. For instance, fetch-pack explicitly re-reads the object directory after performing its fetch, and would be confused if we didn't clear the cache.

2018-11-13sha1-file: use an object_directory for the main object dirLibravatar Jeff King1-14/+3
Our handling of alternate object directories is needlessly different from the main object directory. As a result, many places in the code basically look like this: do_something(r->objects->objdir); for (odb = r->objects->alt_odb_list; odb; odb = odb->next) do_something(odb->path); That gets annoying when do_something() is non-trivial, and we've resorted to gross hacks like creating fake alternates (see find_short_object_filename()). Instead, let's give each raw_object_store a unified list of object_directory structs. The first will be the main store, and everything after is an alternate. Very few callers even care about the distinction, and can just loop over the whole list (and those who care can just treat the first element differently). A few observations: - we don't need r->objects->objectdir anymore, and can just mechanically convert that to r->objects->odb->path - object_directory's path field needs to become a real pointer rather than a FLEX_ARRAY, in order to fill it with expand_base_dir() - we'll call prepare_alt_odb() earlier in many functions (i.e., outside of the loop). This may result in us calling it even when our function would be satisfied looking only at the main odb. But this doesn't matter in practice. It's not a very expensive operation in the first place, and in the majority of cases it will be a noop. We call it already (and cache its results) in prepare_packed_git(), and we'll generally check packs before loose objects. So essentially every program is going to call it immediately once per program. Arguably we should just prepare_alt_odb() immediately upon setting up the repository's object directory, which would save us sprinkling calls throughout the code base (and forgetting to do so has been a source of subtle bugs in the past). But I've stopped short of that here, since there are already a lot of other moving parts in this patch. - Most call sites just get shorter. The check_and_freshen() functions are an exception, because they have entry points to handle local and nonlocal directories separately.

2018-11-13handle alternates paths the same as the main object dirLibravatar Jeff King1-2/+6
When we generate loose file paths for the main object directory, the caller provides a buffer to loose_object_path (formerly sha1_file_name). The callers generally keep their own static buffer to avoid excessive reallocations. But for alternate directories, each struct carries its own scratch buffer. This is needlessly different; let's unify them. We could go either direction here, but this patch moves the alternates struct over to the main directory style (rather than vice-versa). Technically the alternates style is more efficient, as it avoids rewriting the object directory name on each call. But this is unlikely to matter in practice, as we avoid reallocations either way (and nobody has ever noticed or complained that the main object directory is copying a few extra bytes before making a much more expensive system call). And this has the advantage that the reusable buffers are tied to particular calls, which makes the invalidation rules simpler (for example, the return value from stat_sha1_file() used to be invalidated by basically any other object call, but now it is affected only by other calls to stat_sha1_file()). We do steal the trick from alt_sha1_path() of returning a pointer to the filled buffer, which makes a few conversions more convenient.

In preparation for unifying the handling of alt odb's and the normal repo object directory, let's use a more neutral name.

2018-08-29convert "oidcmp() == 0" to oideq()Libravatar Jeff King1-1/+1
Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

2018-05-11get_short_oid: sort ambiguous objects by type, then SHA-1Libravatar Ævar Arnfjörð Bjarmason1-1/+36
Change the output emitted when an ambiguous object is encountered so that we show tags first, then commits, followed by trees, and finally blobs. Within each type we show objects in hashcmp() order. Before this change the objects were only ordered by hashcmp(). The reason for doing this is that the output looks better as a result, e.g. the v2.17.0 tag before this change on "git show e8f2" would display: hint: The candidates are: hint: e8f2093055 tree hint: e8f21caf94 commit 2013-06-24 - bash prompt: print unique detached HEAD abbreviated object name hint: e8f21d02f7 blob hint: e8f21d577c blob hint: e8f25a3a50 tree hint: e8f26250fa commit 2017-02-03 - Merge pull request #996 from jeffhostetler/jeffhostetler/register_rename_src hint: e8f2650052 tag v2.17.0 hint: e8f2867228 blob hint: e8f28d537c tree hint: e8f2a35526 blob hint: e8f2bc0c06 commit 2015-05-10 - Documentation: note behavior for multiple remote.url entries hint: e8f2cf6ec0 tree Now we'll instead show: hint: e8f2650052 tag v2.17.0 hint: e8f21caf94 commit 2013-06-24 - bash prompt: print unique detached HEAD abbreviated object name hint: e8f26250fa commit 2017-02-03 - Merge pull request #996 from jeffhostetler/jeffhostetler/register_rename_src hint: e8f2bc0c06 commit 2015-05-10 - Documentation: note behavior for multiple remote.url entries hint: e8f2093055 tree hint: e8f25a3a50 tree hint: e8f28d537c tree hint: e8f2cf6ec0 tree hint: e8f21d02f7 blob hint: e8f21d577c blob hint: e8f2867228 blob hint: e8f2a35526 blob Since we show the commit data in the output that's nicely aligned once we sort by object type. The decision to show tags before commits is pretty arbitrary. I don't want to order by object_type since there tags come last after blobs, which doesn't make sense if we want to show the most important things first. I could display them after commits, but it's much less likely that we'll display a tag, so if there is one it makes sense to show it prominently at the top. A note on the implementation: Derrick rightly pointed out[1] that we're bending over backwards here in get_short_oid() to first de-duplicate the list, and then emit it, but could simply do it in one step. The reason for that is that oid_array_for_each_unique() doesn't actually require that the array be sorted by oid_array_sort(), it just needs to be sorted in some order that guarantees that all objects with the same ID are adjacent to one another, which (barring a hash collision, which'll be someone else's problem) the sort_ambiguous() function does. I agree that would be simpler for this code, and had forgotten why I initially wrote it like this[2]. But on further reflection I think it's better to do more work here just so we're not underhandedly using the oid-array API where we lie about the list being sorted. That would break any subsequent use of oid_array_lookup() in subtle ways. I could get around that by hacking the API itself to support this use-case and documenting it, which I did as a WIP patch in [3], but I think it's too much code smell just for this one call site. It's simpler for the API to just introduce a oid_array_for_each() function to eagerly spew out the list without sorting or de-duplication, and then do the de-duplication and sorting in two passes. 1. https://public-inbox.org/git/20180501130318.58251-1-dstolee@microsoft.com/ 2. https://public-inbox.org/git/876047ze9v.fsf@evledraar.gmail.com/ 3. https://public-inbox.org/git/874ljrzctc.fsf@evledraar.gmail.com/ Helped-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
