Merge branch 'sb/oid-object-info'

2018-05-23T05:38:16Z

The codepath around object-info API has been taught to take the repository object (which in turn tells the API which object store the objects are to be located). * sb/oid-object-info: cache.h: allow oid_object_info to handle arbitrary repositories packfile: add repository argument to cache_or_unpack_entry packfile: add repository argument to unpack_entry packfile: add repository argument to read_object packfile: add repository argument to packed_object_info packfile: add repository argument to packed_to_object_type packfile: add repository argument to retry_bad_packed_offset cache.h: add repository argument to oid_object_info cache.h: add repository argument to oid_object_info_extended

Merge branch 'ds/commit-graph'

2018-05-08T06:59:20Z

Precompute and store information necessary for ancestry traversal in a separate file to optimize graph walking. * ds/commit-graph: commit-graph: implement "--append" option commit-graph: build graph from starting commits commit-graph: read only from specific pack-indexes commit: integrate commit graph with commit parsing commit-graph: close under reachability commit-graph: add core.commitGraph setting commit-graph: implement git commit-graph read commit-graph: implement git-commit-graph write commit-graph: implement write_commit_graph() commit-graph: create git-commit-graph builtin graph: add commit graph design document commit-graph: add format document csum-file: refactor finalize_hashfile() method csum-file: rename hashclose() to finalize_hashfile()

packfile: convert find_pack_entry to object_id

2018-05-02T04:59:49Z

Convert find_pack_entry and the static function fill_pack_entry to take pointers to struct object_id. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

packfile: convert has_sha1_pack to object_id

2018-05-02T04:59:49Z

Convert this function to take a pointer to struct object_id and rename it has_object_pack for consistency with has_object_file. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

cache.h: allow oid_object_info to handle arbitrary repositories

2018-04-26T01:54:28Z

This involves also adapting oid_object_info_extended and a some internal functions that are used to implement these. It all has to happen in one patch, because of a single recursive chain of calls visits all these functions. oid_object_info_extended is also used in partial clones, which allow fetching missing objects. As this series will not add the repository struct to the transport code and fetch_object(), add a TODO note and omit fetching if a user tries to use a partial clone in a repository other than the_repository. Among the functions modified to handle arbitrary repositories, unpack_entry() is one of them. Note that it still references the globals "delta_base_cache" and "delta_base_cached", but those are safe to be referenced (the former is indexed partly by "struct packed_git *", which is repo-specific, and the latter is only used to limit the size of the former as an optimization).

packfile: add repository argument to unpack_entry

2018-04-26T01:54:27Z

Add a repository argument to allow the callers of unpack_entry to be more specific about which repository to act on. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. As with the previous commits, use a macro to catch callers passing a repository other than the_repository at compile time.

Merge branch 'sb/object-store'

2018-04-11T04:09:55Z

Refactoring the internal global data structure to make it possible to open multiple repositories, work with and then close them. Rerolled by Duy on top of a separate preliminary clean-up topic. The resulting structure of the topics looked very sensible. * sb/object-store: (27 commits) sha1_file: allow sha1_loose_object_info to handle arbitrary repositories sha1_file: allow map_sha1_file to handle arbitrary repositories sha1_file: allow map_sha1_file_1 to handle arbitrary repositories sha1_file: allow open_sha1_file to handle arbitrary repositories sha1_file: allow stat_sha1_file to handle arbitrary repositories sha1_file: allow sha1_file_name to handle arbitrary repositories sha1_file: add repository argument to sha1_loose_object_info sha1_file: add repository argument to map_sha1_file sha1_file: add repository argument to map_sha1_file_1 sha1_file: add repository argument to open_sha1_file sha1_file: add repository argument to stat_sha1_file sha1_file: add repository argument to sha1_file_name sha1_file: allow prepare_alt_odb to handle arbitrary repositories sha1_file: allow link_alt_odb_entries to handle arbitrary repositories sha1_file: add repository argument to prepare_alt_odb sha1_file: add repository argument to link_alt_odb_entries sha1_file: add repository argument to read_info_alternates sha1_file: add repository argument to link_alt_odb_entry sha1_file: add raw_object_store argument to alt_odb_usable pack: move approximate object count to object store ...
