* [PATCH v2 3/5] worktree.c: kill parse_ref() in favor of refs_resolve_ref_unsafe()

The manual parsing code is replaced with a call to refs_resolve_ref_unsafe().
The manual parsing code must die because only refs/files-backend.c
should do that.

files-backend at this point is still aware of the per-repo/worktree
separation in refs, so it can handle a linked worktree.
Note: accessing a worktree of a submodule remains unaddressed. Perhaps
after get_worktrees() can access submodule (or rather a new function
get_submodule_worktrees(), that lists worktrees of a submodule), we can
update this function to work with submodules as well.

v2 still kills parse_ref(), but the series now depends on my other
series [1] and as a result does not make any confusing "submodule"
calls any more.
It also kills another function, introduced for multi-worktree, that
should not have been there to begin with. Good riddance.
Again, the naming convention with refs_ prefix for new APIs may not be
the best idea...

Since submodule or not is irrelevant to files-backend after the last
patch, remove the parameter from files_downcast() and kill
files_assert_main_repository().
PS. This implies that all ref operations are allowed for submodules. But
we may need to look more closely to see if that's really true...

* [PATCH v2 14/16] refs: move submodule code out of files-backend.c
From: Nguyễn Thái Ngọc Duy @ 2017-02-16 11:48 UTC (permalink / raw)

In-Reply-To: <20170216114818.6080-1-pclouds@gmail.com>
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().
The new code in init_submodule_ref_store() is basically a copy of
strbuf_git_path_submodule().
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() follows shortly. It's separate to keep
noises from this patch.

In-Reply-To: <20170216114818.6080-1-pclouds@gmail.com>
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.

* [PATCH v2 11/16] refs.c: kill register_ref_store(), add register_submodule_ref_store()

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().

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. After this the patch to delete
that code will be cleaner.

With get_main_ref_store() being used inside get_ref_store(),
lookup_ref_store() is only used for submodule code path. Rename to
reflect that and delete dead code.

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.

This centralizes all path rewriting of files-backend.c in one place so
we have easier time removing the path rewriting later. There could be
some hidden indirect git_path() though, I didn't audit the code to the
bottom.
Side note: set_worktree_head_symref() is a bad boy and should not be in
files-backend.c (probably should not exist in the first place). But
we'll leave it there until we have better multi-worktree support in refs
before we update it.

* [PATCH v2 03/16] files-backend: add files_path()
From: Nguyễn Thái Ngọc Duy @ 2017-02-16 11:48 UTC (permalink / raw)
To: git

In-Reply-To: <20170216114818.6080-1-pclouds@gmail.com>
This will be the replacement for both git_path() and git_path_submodule()
in this file. The idea is backend takes a git path and use that,
oblivious of submodule, linked worktrees and such.
This is the middle step towards that. Eventually the "submodule" field
in 'struct files_ref_store' should be replace by "gitdir". And a
compound ref_store is created to combine two files backends together,
one represents the shared refs in $GIT_COMMON_DIR, one per-worktree. At
that point, files_path() becomes a wrapper of strbuf_vaddf().

* [PATCH v2 02/16] files-backend: convert git_path() to strbuf_git_path()

In-Reply-To: <20170216114818.6080-1-pclouds@gmail.com>
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.

In some places static size buffers can't store formatted string.
If it be happen then git die.

add git_psprintf helper function

Git can't run bisect between 2048+ commits if use russian translation.
Reproduce "LANG=ru_RU.UTF8 git bisect start v4.9 v4.8" on linux sources.
Dummy solution: just increase buffer size but is not safe.
Size gettext string is a runtime value.
