2017-04-14refs: new transaction related ref-store apiLibravatar Nguyễn Thái Ngọc Duy3-12/+53
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 <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-04-14refs: add new ref-store apiLibravatar Nguyễn Thái Ngọc Duy4-99/+270
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 <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-04-14refs: rename get_ref_store() to get_submodule_ref_store() and make it publicLibravatar Nguyễn Thái Ngọc Duy3-16/+19
This function is intended to replace *_submodule() refs API. It provides a ref store for a specific submodule, which can be operated on by a new set of refs API. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-04-14files-backend: replace submodule_allowed check in files_downcast()Libravatar Nguyễn Thái Ngọc Duy3-37/+73
files-backend.c is unlearning submodules. Instead of having a specific check for submodules to see what operation is allowed, files backend now takes a set of flags at init. Each operation will check if the required flags is present before performing. For now we have four flags: read, write and odb access. Main ref store has all flags, obviously, while submodule stores are read-only and have access to odb (*). The "main" flag stays because many functions in the backend calls frontend ones without a ref store, so these functions always target the main ref store. Ideally the flag should be gone after ref-store-aware api is in place and used by backends. (*) Submodule code needs for_each_ref. Try take REF_STORE_ODB flag out. At least t3404 would fail. The "have access to odb" in submodule is a bit hacky since we don't know from he whether add_submodule_odb() has been called.

2017-03-27refs: move submodule code out of files-backend.cLibravatar Nguyễn Thái Ngọc Duy3-32/+20
files-backend is now initialized with a $GIT_DIR. Converting a submodule path to where real submodule gitdir is located is done in get_ref_store(). This gives a slight performance improvement for submodules since we don't convert submodule path to gitdir at every backend call like before. We pay that once at ref-store creation. More cleanup in files_downcast() and files_assert_main_repository() follows shortly. It's separate to keep noises from this patch.

2017-03-27refs.c: make get_main_ref_store() public and use itLibravatar Nguyễn Thái Ngọc Duy3-19/+22
get_ref_store() will soon be renamed to get_submodule_ref_store(). Together with future get_worktree_ref_store(), the three functions provide an appropriate ref store for different operation modes. New APIs will be added to operate directly on ref stores. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-27refs.c: kill register_ref_store(), add register_submodule_ref_store()Libravatar Nguyễn Thái Ngọc Duy1-25/+20
This is the last function in this code (besides public API) that takes submodule argument and handles both main/submodule cases. Break it down, move main store registration in get_main_ref_store() and keep the rest in register_submodule_ref_store().

2017-03-27refs.c: flatten get_ref_store() a bitLibravatar Nguyễn Thái Ngọc Duy1-10/+13
This helps the future changes in this code. And because get_ref_store() is destined to become get_submodule_ref_store(), the "get main store" code path will be removed eventually.

2017-03-27files-backend: remove the use of git_path()Libravatar Nguyễn Thái Ngọc Duy1-5/+38
Given $GIT_DIR and $GIT_COMMON_DIR, files-backend is now in charge of deciding what goes where (*). The end goal is to pass $GIT_DIR only. A refs "view" of a linked worktree is a logical ref store that combines two files backends together. (*) Not entirely true since strbuf_git_path_submodule() still does path translation underneath. But that's for another patch. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-03-27files-backend: add and use files_ref_path()Libravatar Nguyễn Thái Ngọc Duy1-24/+23
Keep repo-related path handling in one place. This will make it easier to add submodule/multiworktree support later. This automatically adds the "if submodule then use the submodule version of git_path" to other call sites too. But it does not mean those operations are submodule-ready. Not yet.

2017-03-27files-backend: convert git_path() to strbuf_git_path()Libravatar Nguyễn Thái Ngọc Duy1-33/+97
git_path() and friends are going to be killed in files-backend.c in near future. And because there's a risk with overwriting buffer in git_path(), let's convert them all to strbuf_git_path(). We'll have easier time killing/converting strbuf_git_path() then because we won't have to worry about memory management again.

2017-03-27files-backend: delete dead code in files_init_db()Libravatar Nguyễn Thái Ngọc Duy1-4/+0
safe_create_dir() can do adjust_shared_perm() internally, and init-db has always created 'refs' in shared mode since the beginning, af6e277c5e (git-init-db: initialize shared repositories with --shared - 2005-12-22). So this code looks like extra adjust_shared_perm calls are unnecessary. And they are. But let's see why there are here in the first place. This code was added in 6fb5acfd8f (refs: add methods to init refs db - 2016-09-04). From the diff alone this looks like a faithful refactored code from init-db.c. But there is a subtle difference: Between the safe_create_dir() block and adjust_shared_perm() block in the old init-db.c, we may copy/recreate directories from the repo template. So it makes sense that adjust_shared_perm() is re-executed then to fix potential permission screwups. After 6fb5acfd8f, refs dirs are created after template is copied. Nobody will change directory permission again. So the extra adjust_shared_perm() is redudant. Delete them.

2017-03-27files-backend.c: delete dead code in files_ref_iterator_begin()Libravatar Nguyễn Thái Ngọc Duy1-3/+0
It's not in the diff context, but files_downcast() is called before this check. If "refs" is NULL, we would have segfaulted before reaching the check here.

2017-03-17Merge branch 'bc/sha1-header-selection-with-cpp-macros'Libravatar Junio C Hamano3-8/+20
Our source code has used the SHA1_HEADER cpp macro after "#include" in the C code to switch among the SHA-1 implementations. Instead, list the exact header file names and switch among implementations using "#ifdef BLK_SHA1/#include "block-sha1/sha1.h"/.../#endif"; this helps some IDE tools. * bc/sha1-header-selection-with-cpp-macros: hash.h: move SHA-1 implementation selection into a header file

2017-03-17Merge branch 'jk/add-i-use-pathspecs'Libravatar Junio C Hamano2-11/+45
"git add -p <pathspec>" unnecessarily expanded the pathspec to a list of individual files that matches the pathspec by running "git ls-files <pathspec>", before feeding it to "git diff-index" to see which paths have changes, because historically the pathspec language supported by "diff-index" was weaker. These days they are equivalent and there is no reason to internally expand it. This helps both performance and avoids command line argument limit on some platforms. * jk/add-i-use-pathspecs: add--interactive: do not expand pathspecs with ls-files

The cherry-pick and revert commands use OPT_INTEGER() to parse --mainline. The stock parser is smart enough to reject non-numeric nonsense, but it doesn't know that parent counting starts at 1. Worse, the value "0" is indistinguishable from the unset case, so a user who assumes the counting is 0-based will get a confusing message: $ git cherry-pick -m 0 $merge error: commit ... is a merge but no -m option was given.

2017-03-15hash.h: move SHA-1 implementation selection into a header fileLibravatar brian m. carlson3-8/+20
Many developers use functionality in their editors that allows for quick syntax checks, including warning about questionable constructs. This functionality allows rapid development with fewer errors. However, such functionality generally does not allow the specification of project-specific defines or command-line options. Since the SHA1_HEADER include is not defined in such a case, developers see spurious errors when using these tools. Furthermore, there are known implementations of "cc" whose '#include' is unhappy with this construct. Instead of using SHA1_HEADER, create a hash.h header and use #if and #elif to select the desired header. Have the Makefile pass an appropriate option to help the header select the right implementation to use. [jc: make BLK_SHA1 the fallback default as discussed on list, e.g. <20170314201424.vccij5z2ortq4a4o@sigill.intra.peff.net>; also remove SHA1_HEADER and SHA1_HEADER_SQ that are no longer used].
