git/refs.c, branch v2.13.2

Merge branch 'mh/separate-ref-cache'

2017-04-26T06:39:13Z

The internals of the refs API around the cached refs has been streamlined. * mh/separate-ref-cache: do_for_each_entry_in_dir(): delete function files_pack_refs(): use reference iteration commit_packed_refs(): use reference iteration cache_ref_iterator_begin(): make function smarter get_loose_ref_cache(): new function get_loose_ref_dir(): function renamed from get_loose_refs() do_for_each_entry_in_dir(): eliminate `offset` argument refs: handle "refs/bisect/" in `loose_fill_ref_dir()` ref-cache: use a callback function to fill the cache refs: record the ref_store in ref_cache, not ref_dir ref-cache: introduce a new type, ref_cache refs: split `ref_cache` code into separate files ref-cache: rename `remove_entry()` to `remove_entry_from_dir()` ref-cache: rename `find_ref()` to `find_ref_entry()` ref-cache: rename `add_ref()` to `add_ref_entry()` refs_verify_refname_available(): use function in more places refs_verify_refname_available(): implement once for all backends refs_ref_iterator_begin(): new function refs_read_raw_ref(): new function get_ref_dir(): don't call read_loose_refs() for "refs/bisect"

Merge branch 'jk/quarantine-received-objects'

2017-04-24T05:07:52Z

Add finishing touches to a recent topic. * jk/quarantine-received-objects: refs: reject ref updates while GIT_QUARANTINE_PATH is set receive-pack: document user-visible quarantine effects receive-pack: drop tmp_objdir_env from run_update_hook

Merge branch 'nd/files-backend-git-dir'

2017-04-20T04:37:19Z

The "submodule" specific field in the ref_store structure is replaced with a more generic "gitdir" that can later be used also when dealing with ref_store that represents the set of refs visible from the other worktrees. * nd/files-backend-git-dir: (28 commits) refs.h: add a note about sorting order of for_each_ref_* t1406: new tests for submodule ref store t1405: some basic tests on main ref store t/helper: add test-ref-store to test ref-store functions refs: delete pack_refs() in favor of refs_pack_refs() files-backend: avoid ref api targeting main ref store refs: new transaction related ref-store api refs: add new ref-store api refs: rename get_ref_store() to get_submodule_ref_store() and make it public files-backend: replace submodule_allowed check in files_downcast() refs: move submodule code out of files-backend.c path.c: move some code out of strbuf_git_path_submodule() refs.c: make get_main_ref_store() public and use it refs.c: kill register_ref_store(), add register_submodule_ref_store() refs.c: flatten get_ref_store() a bit refs: rename lookup_ref_store() to lookup_submodule_ref_store() refs.c: introduce get_main_ref_store() files-backend: remove the use of git_path() files-backend: add and use files_ref_path() files-backend: add and use files_reflog_path() ...

refs_verify_refname_available(): implement once for all backends

2017-04-17T04:32:45Z

It turns out that we can now implement `refs_verify_refname_available()` based on the other virtual functions, so there is no need for it to be defined at the backend level. Instead, define it once in `refs.c` and remove the `files_backend` definition. Signed-off-by: Michael Haggerty Signed-off-by: Junio C Hamano

refs: reject ref updates while GIT_QUARANTINE_PATH is set

2017-04-17T01:19:18Z

As documented in git-receive-pack(1), updating a ref from within the pre-receive hook is dangerous and can corrupt your repo. This patch forbids ref updates entirely during the hook to make it harder for adventurous hook writers to shoot themselves in the foot. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

refs_ref_iterator_begin(): new function

2017-04-14T10:54:31Z

Extract a new function from `do_for_each_ref()`. It will be useful elsewhere. Signed-off-by: Michael Haggerty Signed-off-by: Junio C Hamano

refs_read_raw_ref(): new function

2017-04-14T10:54:31Z

Extract a new function from `refs_resolve_ref_unsafe()`. It will be useful elsewhere. Signed-off-by: Michael Haggerty Signed-off-by: Junio C Hamano

refs: delete pack_refs() in favor of refs_pack_refs()

2017-04-14T10:53:25Z

It only has one caller, not worth keeping just for convenience. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

refs: new transaction related ref-store api

2017-04-14T10:53:25Z

The transaction struct now takes a ref store at creation and will operate on that ref store alone. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

refs: add new ref-store api

2017-04-14T10:53:25Z

This is not meant to cover all existing API. It adds enough to test ref stores with the new test program test-ref-store, coming soon and to be used by files-backend.c. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano
