565fb8dc	2016-06-25T20:02:45	revwalk: introduce tests that hide old commits Introduce some tests that show some commits, while hiding some commits that have a timestamp older than the common ancestors of these two commits.
becadafc	2016-08-05T19:30:56	odb: only provide the empty tree Only provide the empty tree internally, which matches git's behavior. If we provide the empty blob then any users trying to write it with libgit2 would omit it from actually landing in the odb, which appear to git proper as a broken repository (missing that object).
27051d4e	2016-07-22T13:34:19	odb: only freshen pack files every 2 seconds Since writing multiple objects may all already exist in a single packfile, avoid freshening that packfile repeatedly in a tight loop. Instead, only freshen pack files every 2 seconds.
8f09a98e	2016-07-14T16:23:24	odb: freshen existing objects when writing When writing an object, we calculate its OID and see if it exists in the object database. If it does, we need to freshen the file that contains it.
9a786650	2016-03-09T11:00:27	odb: Handle corner cases in `git_odb_expand_ids` The old implementation had two issues: 1. OIDs that were too short as to be ambiguous were not being handled properly. 2. If the last OID to expand in the array was missing from the ODB, we would leak a `GIT_ENOTFOUND` error code from the function.
62484f52	2016-03-08T14:09:55	git_odb_expand_ids: accept git_odb_expand_id array Take (and write to) an array of a struct, `git_odb_expand_id`.
4b1f0f79	2016-03-08T11:44:21	git_odb_expand_ids: rename func, return the type
6c04269c	2016-03-04T00:50:35	git_odb_exists_many_prefixes: query odb for multiple short ids Query the object database for multiple objects at a time, given their object ID (which may be abbreviated) and optional type.
a0a1b19a	2015-10-14T19:31:54	odb: Prioritize alternate backends For most real use cases, repositories with alternates use them as main object storage. Checking the alternate for objects before the main repository should result in measurable speedups. Because of this, we're changing the sorting algorithm to prioritize alternates in cases where two backends have the same priority. This means that the pack backend for the alternate will be checked before the pack backend for the main repository but both of them will be checked before any loose backends.
d3b29fb9	2015-10-01T00:50:37	refdb and odb backends must provide `free` function As refdb and odb backends can be allocated by client code, libgit2 can’t know whether an alternative memory allocator was used, and thus should not try to call `git__free` on those objects. Instead, odb and refdb backend implementations must always provide their own `free` functions to ensure memory gets freed correctly.
ac2fba0e	2015-09-16T15:07:27	git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.
8da44047	2015-06-06T03:55:28	path: error out if the callback returns an error When the callback returns an error, we should stop immediately. This broke when trying to make sure we pass specific errors up the chain. This broke cancelling out of the loose backend's foreach.
e0156651	2014-11-21T13:50:46	odb: `git_odb_object` contents are never NULL This is a contract that we made in the library and that we need to uphold. The contents of a blob can never be NULL because several parts of the library (including the filter and attributes code) expect `git_blob_rawcontent` to always return a valid pointer.
e1ac0101	2014-11-08T14:40:53	odb: hardcode the empty blob and tree git hardocodes these as objects which exist regardless of whether they are in the odb and uses them in the shell interface as a way of expressing the lack of a blob or tree for one side of e.g. a diff. In the library we use each language's natural way of declaring a lack of value which makes a workaround like this unnecessary. Since git uses it, it does however mean each shell application would need to perform this check themselves. This makes it common work across a range of applications and an issue with compatibility with git, which fits right into what the library aims to provide. Thus we introduce the hard-coded empty blob and tree in the odb frontend. These hard-coded objects are checked for before going to the backends, but after the cache check, which means the second time they're used, they will be treated as normal cached objects instead of creating new ones.

430866d2	2014-05-20T08:29:51	Fix a leak in the tests
ee311907	2014-05-05T16:04:14	odb: ignore files in the objects dir We assume that everything under GIT_DIR/objects/ is a directory. This is not necessarily the case if some process left a stray file in there. Check beforehand if we do have a directory and ignore the entry otherwise.
89499078	2014-03-10T10:53:39	Fix a number of git_odb_exists_prefix bugs The git_odb_exists_prefix API was not dealing correctly when a later backend returned GIT_ENOTFOUND even if an earlier backend had found the object. Additionally, the unit tests were not properly exercising the API and had a couple mistakes in checking the results. Lastly, since the backends are not expected to behavior correctly unless all bytes of the short id are zero except for the prefix, this makes the ODB prefix APIs explicitly clear out the extra bytes so the user doesn't have to be as careful.

a064dc2d	2014-03-06T00:47:05	Merge pull request #2159 from libgit2/rb/odb-exists-prefix Add ODB API to check for existence by prefix and object id shortener

25e0b157	2013-12-06T15:07:57	Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
