A pathname that begins with "//" or "\\" on Windows is special but
path normalization logic was unaware of it.
* js/normalize-path-copy-ceil:
normalize_path_copy(): fix pushing to //server/share/dir on Windows

normalize_path_copy() is not prepared to keep the double-slash of a
//server/share/dir kind of path, but treats it like a regular POSIX
style path and transforms it to /server/share/dir.
The bug manifests when 'git push //server/share/dir master' is run,
because tmp_objdir_add_as_alternate() uses the path in normalized
form when it registers the quarantine object database via
link_alt_odb_entries(). Needless to say that the directory cannot be
accessed using the wrongly normalized path.
Fix it by skipping all of the root part, not just a potential drive
prefix. offset_1st_component takes care of this, see the
implementation in compat/mingw.c::mingw_offset_1st_component().

The code that we have used for the past 10+ years to cycle
4-element ring buffers turns out to be not quite portable in
theoretical world.

Overflow is defined for unsigned integers, but not for signed ones.
We could make the ring-buffer index in sha1_to_hex() and
get_pathname() unsigned to be on the safe side to resolve this, but
let's make it explicit that we are wrapping around at whatever the
number of elements the ring-buffer has. The compiler is smart enough
to turn modulus into bitmask for these codepaths that use
ring-buffers of a size that is a power of 2.

Currently, do_submodule_path will attempt locating the .git directory by
using read_gitfile on <path>/.git. If this fails it just assumes the
<path>/.git is actually a git directory.
This is good because it allows for handling submodules which were cloned
in a regular manner first before being added to the superproject.
Unfortunately this fails if the <path> is not actually checked out any
longer, such as by removing the directory.
Fix this by checking if the directory we found is actually a gitdir. In
the case it is not, attempt to lookup the submodule configuration and
find the name of where it is stored in the .git/modules/ directory of
the superproject.
If we can't locate the submodule configuration, this might occur because
for example a submodule gitlink was added but the corresponding
.gitmodules file was not properly updated. A die() here would not be
pleasant to the users of submodule diff formats, so instead, modify
do_submodule_path() to return an error code:
- git_pathdup_submodule() returns NULL when we fail to find a path.
- strbuf_git_path_submodule() propagates the error code to the caller.
Modify the callers of these functions to check the error code and fail
properly. This ensures we don't attempt to use a bad path that doesn't
match the corresponding submodule.
Because this change fixes add_submodule_odb() to work even if the
submodule is not checked out, update the wording of the submodule log
diff format to correctly display that the submodule is "not initialized"
instead of "not checked out"
Add tests to ensure this change works as expected.

The idea of the --git-path option is not only to avoid having to
prefix paths with the output of --git-dir all the time, but also to
respect overrides for specific common paths inside the .git directory
(e.g. `git rev-parse --git-path objects` will report the value of the
environment variable GIT_OBJECT_DIRECTORY, if set).
When introducing the core.hooksPath setting, we forgot to adjust
git_path() accordingly. This patch fixes that.
While at it, revert the special-casing of core.hooksPath in
run-command.c, as it is now no longer needed.

do_git_path(), which is the common code for all git_path* functions, is
modified to take a worktree struct and can produce paths for any
worktree.
worktree_git_path() is the first function that makes use of this. It can
be used to write code that can examine any worktree. For example,
wt_status_get_state() will be converted using this to take
am/rebase/... state of any worktree.

These are mostly convenient functions to reduce code duplication. Most
of the time, we should be able to get by with git_path() which handles
$GIT_COMMON_DIR internally. However there are a few cases where we need
to construct paths manually, for example some paths from a specific
worktree. These functions will enable that.

The repository set-up sequence has been streamlined (the biggest

It would be useful to control access to the global
shared_repository, so that we can lazily load its config.
The first step to doing so is to make sure all access
goes through a set of functions.
This step is purely mechanical, and should result in no
change of behavior.

On Windows, the backslash is the native directory separator, but all
supported Windows versions also accept the forward slash in most
circumstances.
Our tests expect forward slashes.
Relative paths are generated by Git using forward slashes.
So let's try to be consistent and use forward slashes in the $HOME part
of the paths reported by `git config --show-origin`, too.

Junio noticed that there is an implicit assumption in pretty much
all the code calling has_dos_drive_prefix(): it forces all of its
callsites to hardcode the knowledge that the DOS drive prefix is
always two bytes long.
While this assumption is pretty safe, we can still make the code
more readable and less error-prone by introducing a function that
skips the DOS drive prefix safely.
While at it, we change the has_dos_drive_prefix() return value: it
now returns the number of bytes to be skipped if there is a DOS
drive prefix.

The hook to report "garbage" files in $GIT_OBJECT_DIRECTORY/pack/
could be generic but is too specific to count-object's needs.
Move the part to produce human-readable messages to count-objects,
and refine the interface to callback with the "bits" with values
defined in the cache.h header file, so that other callers (e.g.
prune) can later use the same mechanism to enumerate different
kinds of garbage files and do something intelligent about them,
other than reporting in textual messages.

When working with paths in strbufs, we frequently want to
ensure that a directory contains a trailing slash before
appending to it. We can shorten this code (and make the
intent more obvious) by calling strbuf_complete.
Most of these cases are trivially identical conversions, but
there are two things to note:
- in a few cases we did not check that the strbuf is
non-empty (which would lead to an out-of-bounds memory
access). These were generally not triggerable in
practice, either from earlier assertions, or typically
because we would have just fed the strbuf to opendir(),
which would choke on an empty path.
- in a few cases we indexed the buffer with "original_len"
or similar, rather than the current sb->len, and it is
not immediately obvious from the diff that they are the
same. In all of these cases, I manually verified that
the strbuf does not change between the assignment and
the strbuf_complete call.
This does not convert cases which look like:
if (sb->len && !is_dir_sep(sb->buf[sb->len - 1]))
strbuf_addch(sb, '/');
as those are obviously semantically different. Some of these
cases arguably should be doing that, but that is out of
scope for this change, which aims purely for cleanup with no
behavior change (and at least it will make such sites easier
to find and examine in the future, as we can grep for
strbuf_complete).

This function strcpy's directly into a PATH_MAX-sized
buffer. There's only one caller, which feeds the git_dir into
it, so it's not easy to trigger in practice (even if you fed
a large $GIT_DIR through the environment or .git file, it
would have to actually exist and be accessible on the
filesystem to get to this point). We can fix it by moving to
a strbuf.

We use two PATH_MAX-sized buffers to represent the repo
path, and must make sure not to overflow them. We do take
care to check the lengths, but the logic is rather hard to
follow, as we use several magic numbers (e.g., "PATH_MAX -
10"). And in fact you _can_ overflow the buffer if you have
a ".git" file with an extremely long path in it.
By switching to strbufs, these problems all go away. We do,
however, retain the check that the initial input we get is
no larger than PATH_MAX. This function is an entry point for
untrusted repo names from the network, and it's a good idea
to keep a sanity check (both to avoid allocating arbitrary
amounts of memory, and also as a layer of defense against
any downstream users of the names).

If you have a function that uses git_path a lot, but would
prefer to avoid the static buffers, it's useful to keep a
single scratch buffer locally and reuse it for each call.
You used to be able to do this with git_snpath:
char buf[PATH_MAX];
foo(git_snpath(buf, sizeof(buf), "foo"));
bar(git_snpath(buf, sizeof(buf), "bar"));
but since 1a83c24, git_snpath has been replaced with
strbuf_git_path. This is good, because it removes the
arbitrary PATH_MAX limit. But using strbuf_git_path is more
awkward for two reasons:
1. It adds to the buffer, rather than replacing it. This
is consistent with other strbuf functions, but makes
reuse of a single buffer more tedious.
2. It doesn't return the buffer, so you can't format
as part of a function's arguments.
The new git_path_buf solves both of these, so you can use it
like:
struct strbuf buf = STRBUF_INIT;
foo(git_path_buf(&buf, "foo"));
bar(git_path_buf(&buf, "bar"));
strbuf_release(&buf);

The normalize_ceiling_entry() function does not muck with the end
of the path it accepts, and the real world callers do rely on that,
but a test insisted that the function drops a trailing slash.

In normalize_ceiling_entry(), we test that normalized paths end with
slash, *unless* the path to be normalized was already the root
directory.
However, normalize_path_copy() does not even enforce this condition.
Even worse: on Windows, the root directory gets translated into a
Windows directory by the Bash before being passed to `git.exe` (or
`test-path-utils.exe`), which means that we cannot even know whether
the path that was passed to us was the root directory to begin with.
This issue has already caused endless hours of trying to "fix" the
MSYS2 runtime, only to break other things due to MSYS2 ensuring that
the converted path maintains the same state as the input path with
respect to any final '/'.
So let's just forget about this test. It is non-essential to Git's
operation, anyway.

Strict mode is about not guessing where .git is. If the user points to a
.git file, we know exactly where the target .git dir will be. This makes
it possible to serve .git files as repository on the server side.
This may be needed even in local clone case because transport.c code
uses upload-pack for fetching remote refs. But right now the
clone/transport code goes with non-strict.

When submodule is a linked worktree, "git diff --submodule" and other
calls which directly access the submodule's object database do not correctly
calculate its path. Fix it by changing the git_pathdup_submodule() behavior,
to use either common or per-worktree directory.
Do it similarly as for parent repository, but ignore the GIT_COMMON_DIR
environment variable, because it would mean common directory for the parent
repository and does not make sense for submodule.
Also add test for functionality which uses this call.

We need the place we stick refs for bisects in progress to not be
shared between worktrees. So we make the refs/bisect/ hierarchy
per-worktree.
The is_per_worktree_ref function and associated docs learn that
refs/bisect/ is per-worktree, as does the git_path code in path.c
The ref-packing functions learn that per-worktree refs should not be
packed (since packed-refs is common rather than per-worktree).
Since refs/bisect is per-worktree, logs/refs/bisect should be too.

Instead of common_list having formatting like ! and /, use a struct to
hold common_list data in a structured form.
We don't use 'exclude' yet; instead, we keep the old codepath that
handles info/sparse-checkout and logs/HEAD. Later, we will use exclude.

One of the most common uses of git_path() is to pass a
constant, like git_path("MERGE_MSG"). This has two
drawbacks:
1. The return value is a static buffer, and the lifetime
is dependent on other calls to git_path, etc.
2. There's no compile-time checking of the pathname. This
is OK for a one-off (after all, we have to spell it
correctly at least once), but many of these constant
strings appear throughout the code.
This patch introduces a series of functions to "memoize"
these strings, which are essentially globals for the
lifetime of the program. We compute the value once, take
ownership of the buffer, and return the cached value for
subsequent calls. cache.h provides a helper macro for
defining these functions as one-liners, and defines a few
common ones for global use.
Using a macro is a little bit gross, but it does nicely
document the purpose of the functions. If we need to touch
them all later (e.g., because we learned how to change the
git_dir variable at runtime, and need to invalidate all of
the stored values), it will be much easier to have the
complete list.
Note that the shared-global functions have separate, manual
declarations. We could do something clever with the macros
(e.g., expand it to a declaration in some places, and a
declaration _and_ a definition in path.c). But there aren't
that many, and it's probably better to stay away from
too-magical macros.
Likewise, if we abandon the C preprocessor in favor of
generating these with a script, we could get much fancier.
E.g., normalizing "FOO/BAR-BAZ" into "git_path_foo_bar_baz".
But the small amount of saved typing is probably not worth
the resulting confusion to readers who want to grep for the
function's definition.

The git_path function has "git_pathdup" and
"strbuf_git_path" variants, but git_submodule_path only
comes in the dangerous, static-buffer variant. That makes
refactoring callers to use the safer functions hard (since
they don't exist).
Since we're already using a strbuf behind the scenes, it's
easy to expose all three of these interfaces with thin
wrappers.

home_config_paths() combines distinct functionality already implemented
by expand_user_path() and xdg_config_home(), and it also hard-codes the
path ~/.gitconfig, which makes it unsuitable to use for other home
config file paths. Since its use will just add unnecessary complexity to
the code, remove it.

The XDG base dir spec[1] specifies that configuration files be stored in
a subdirectory in $XDG_CONFIG_HOME. To construct such a configuration
file path, home_config_paths() can be used. However, home_config_paths()
combines distinct functionality:
1. Retrieve the home git config file path ~/.gitconfig
2. Construct the XDG config path of the file specified by `file`.
This function was introduced in commit 21cf3227 ("read (but not write)
from $XDG_CONFIG_HOME/git/config file"). While the intention of the
function was to allow the home directory configuration file path and the
xdg directory configuration file path to be retrieved with one function
call, the hard-coding of the path ~/.gitconfig prevents it from being
used for other configuration files. Furthermore, retrieving a file path
relative to the user's home directory can be done with
expand_user_path(). Hence, it can be seen that home_config_paths()
introduces unnecessary complexity, especially if a user just wants to
retrieve the xdg config file path.
As such, implement a simpler function xdg_config_home() for constructing
the XDG base dir spec configuration file path. This function, together
with expand_user_path(), can replace all uses of home_config_paths().
