3993e9ae	2021-11-08T14:00:09	Update documentation for ODB backend refresh logic Commit b1a6c316a6070fac4ab1ec5792979838f7145c39 moved auto-refresh into the pack backend, and added a comment accordingly. Commit 43820f204ea32503b4083e3b6b83f30a0a0031c9 moved auto-refresh back out of backends into the ODB layer, but didn't update the comment.
ea285904	2020-02-18T00:02:13	midx: Introduce git_odb_write_multi_pack_index() This change introduces git_odb_write_multi_pack_index(), which creates a `multi-pack-index` file from all the `.pack` files that have been loaded in the ODB. Fixes: #5399
fefefd1d	2019-06-23T16:42:14	odb: use `git_object_size_t` for object size Instead of using a signed type (`off_t`) use a new `git_object_size_t` for the sizes of objects.
459ac856	2019-02-23T18:42:53	odb: provide a free function for custom backends Custom backends can allocate memory when reading objects and providing them to libgit2. However, if an error occurs in the custom backend after the memory has been allocated for the custom object but before it's returned to libgit2, the custom backend has no way to free that memory and it must be leaked. Provide a free function that corresponds to the alloc function so that custom backends have an opportunity to free memory before they return an error.
790aae77	2019-02-23T18:40:43	odb: rename git_odb_backend_malloc for consistency The `git_odb_backend_malloc` name is a system function that is provided for custom ODB backends and allows them to allocate memory for an ODB object in the read callback. This is important so that libgit2 can later free the memory used by an ODB object that was read from the custom backend. However, the name _suggests_ that it actually allocates a `git_odb_backend`. It does not; rename it to make it clear that it actually allocates backend _data_.
a1ef995d	2019-02-21T10:33:30	indexer: use git_indexer_progress throughout Update internal usage of `git_transfer_progress` to `git_indexer_progreses`.
22d2062d	2019-01-09T18:25:10	Introduce GIT_CALLBACK macro to enforce cdecl Since we now always build the library with cdecl calling conventions, our callbacks should be decorated as such so that users will not be able to provide callbacks defined with other calling conventions. The `GIT_CALLBACK` macro will inject the `__cdecl` attribute as appropriate.

97f9a5f0	2017-12-17T01:12:49	odb: provide length and type with streaming read The streaming read functionality should provide the length and the type of the object, like the normal read functionality does.
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.
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.
41808d04	2015-07-27T14:46:50	Fix @param names in doc comments
77b339f7	2015-05-12T13:06:33	odb: make the writestream's size a git_off_t Restricting files to size_t is a silly limitation. The loose backend writes to a file directly, so there is no issue in using 63 bits for the size. We still assume that the header is going to fit in 64 bytes, which does mean quite a bit smaller files due to the run-length encoding, but it's still a much larger size than you would want Git to handle.
bc91347b	2014-04-30T11:16:31	Fix remaining init_options inconsistencies There were a couple of "init_opts()" functions a few more cases of structure initialization that I somehow missed.

b1a6c316	2013-08-30T17:36:00	odb: Move the auto refresh logic to the pack backend Previously, `git_object_read()`, `git_object_read_prefix()` and `git_object_exists()` were implementing an auto refresh logic. When the expected object couldn't be found in any backend, a call to `git_odb_refresh()` was triggered and the lookup was once again performed against all backends. This commit removes this auto-refresh logic from the odb layer and pushes it down into the pack-backend (as it's the only one currently exposing a `refresh()` endpoint).

Thus the backends should treat it as a read-only value. The positioning in the function signature made it seem as though it was an output parameter.

Some of the stuff related to streaming I left in include/git2 because it seemed like it would be reasonably needed by a normal user who wanted to stream objects into and out of the ODB. Also, I added APIs for traversing the list of backends so that some of the tests would not need to access ODB internals.

Commit 43820f204ea32503b4083e3b6b83f30a0a0031c9 moved auto-refresh back *out* of backends into the ODB layer, but didn't update the comment.
