Plumb "struct key_value_info" through all code paths that end in
die_bad_number(), which lets us remove the helper functions that read
analogous values from "struct config_reader". As a result, nothing reads
config_reader.config_kvi any more, so remove that too.
In config.c, this requires changing the signature of
git_configset_get_value() to 'return' "kvi" in an out parameter so that
git_configset_get_<type>() can pass it to git_config_<type>(). Only
numeric types will use "kvi", so for non-numeric types (e.g.
git_configset_get_string()), pass NULL to indicate that the out
parameter isn't needed.
Outside of config.c, config callbacks now need to pass "ctx->kvi" to any
of the git_config_<type>() functions that parse a config string into a
number type. Included is a .cocci patch to make that refactor.
The only exceptional case is builtin/config.c, where git_config_<type>()
is called outside of a config callback (namely, on user-provided input),
so config source information has never been available. In this case,
die_bad_number() defaults to a generic, but perfectly descriptive
message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure
not to change the message.

Pass config_context when parsing CLI config. To provide the .kvi member,
refactor out kvi_from_param() from the logic that caches CLI config in
configsets. Now that config_context and config_context.kvi is always
present when config machinery calls config callbacks, plumb "kvi" so
that we can remove all calls of current_config_scope() except for
trace2/*.c (which will be handled in a later commit), and remove all
other current_config_*() (the functions themselves and their calls).
Note that this results in .kvi containing a different, more complete
set of information than the mocked up "struct config_source" in
git_config_from_parameters().
Plumbing "kvi" reveals a few places where we've been doing the wrong
thing:
* git_config_parse_parameter() hasn't been setting config source
information, so plumb "kvi" there too.
* Several sites in builtin/config.c have been calling current_config_*()
functions outside of config callbacks (indirectly, via the
format_config() helper), which means they're reading state that isn't
set correctly:
* "git config --get-urlmatch --show-scope" iterates config to collect
values, but then attempts to display the scope after config
iteration, causing the "unknown" scope to be shown instead of the
config file's scope. It's clear that this wasn't intended: we knew
that "--get-urlmatch" couldn't show config source metadata, which is
why "--show-origin" was marked incompatible with "--get-urlmatch"
when it was introduced [1]. It was most likely a mistake that we
allowed "--show-scope" to sneak through.
Fix this by copying the "kvi" value in the collection phase so that
it can be read back later. This means that we can now support "git
config --get-urlmatch --show-origin", but that is left unchanged
for now.
* "git config --default" doesn't have config source metadata when
displaying the default value, so "--show-scope" also results in
"unknown", and "--show-origin" results in a BUG(). Fix this by
treating the default value as if it came from the command line (e.g.
like we do with "git -c" or "git config --file"), using
kvi_from_param().

Pass config_context to config callbacks in configset_iter(), trivially
setting the .kvi member to the cached key_value_info. Then, in config
callbacks that are only used with configsets, use the .kvi member to
replace calls to current_config_*(), and delete current_config_line()
because it has no remaining callers.
This leaves builtin/config.c and config.c as the only remaining users of
current_config_*().

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

Much like with attributes files, sometimes programs would like to know
the location of configuration files at the global or system levels.
However, it isn't always clear where these may live, especially for the
system file, which may have been hard-coded at compile time or computed
dynamically based on the runtime prefix.
Since other parties cannot intuitively know how Git was compiled and
where it looks for these files, help them by providing variables that
can be queried. Because we have multiple paths for global config
values, print them in order from highest to lowest priority, and be sure
to split on newlines so that "git var -l" produces two entries for the
global value.
However, be careful not to split all values on newlines, since our
editor values could well contain such characters, and we don't want to
split them in such a case.
Note in the documentation that some values may contain multiple paths
and that callers should be prepared for that fact. This helps people
write code that will continue to work in the event we allow multiple
items elsewhere in the future.

Currently, there are some programs which would like to read and parse
the gitattributes files at the global or system levels. However, it's
not always obvious where these files live, especially for the system
file, which may have been hard-coded at compile time or computed
dynamically based on the runtime prefix.
It's not reasonable to expect all callers of Git to intuitively know
where the Git distributor or user has configured these locations to
be, so add some entries to allow us to determine their location. Honor
the GIT_ATTR_NOSYSTEM environment variable if one is specified. Expose
the accessor functions in a way that we can reuse them from within the
var code.
In order to make our paths consistent on Windows and also use the same
form as paths use in "git rev-parse", let's normalize the path before we
return it. This results in Windows-style paths that use slashes, which
is convenient for making our tests function in a consistent way across
platforms. Note that this requires that some of our values be freed, so
let's add a flag about whether the value needs to be freed and use it
accordingly.

Right now, all of our values are constants whose allocation is managed
elsewhere. However, in the future, we'll have some variables whose
memory we will need to free. To keep things consistent, let's make each

for freeing it.

On most Unix systems, finding a suitable shell is easy: one simply uses
"sh" with an appropriate PATH value. However, in many Windows
environments, the shell is shipped alongside Git, and it may or may not
be in PATH, even if Git is.
In such an environment, it can be very helpful to query Git for the
shell it's using, since other tools may want to use the same shell as
well. To help them out, let's add a variable, GIT_SHELL_PATH, that
points to the location of the shell.
On Unix, we know our shell must be executable to be functional, so
assume that the distributor has correctly configured their environment,
and use that as a basic test. On Git for Windows, we know that our
shell will be one of a few fixed values, all of which end in "sh" (such
as "bash"). This seems like it might be a nice test on Unix as well,
since it is customary for all shells to end in "sh", but there probably
exist such systems that don't have such a configuration, so be careful
here not to break them.

We abstract the set of variables into a table, with a "read" callback to
provide the value of each. Each callback takes a "flag" argument, but
most callbacks don't make use of it.
This flag is a bit odd. It may be set to IDENT_STRICT, which make sense
for ident-based callbacks, but is just confusing for things like
GIT_EDITOR.
At first glance, it seems like this is just a hack to let us directly
stick the generic git_committer_info() and git_author_info() functions
into our table. And we'd be better off to wrap them with local functions
which pass IDENT_STRICT, and have our callbacks take no option at all.
But that doesn't quite work. We pass IDENT_STRICT when the caller asks
for a specific variable, but otherwise do not (so that "git var -l" does
not bail if the committer ident cannot be formed).
So we really do need to pass in the flag to each invocation, even if the
individual callback doesn't care about it. Let's mark the unused ones so
that -Wunused-parameter does not complain. And while we're here, let's
rename them so that it's clear that the flag values we get will be from
the IDENT_* set. That may prevent confusion for future readers of the
code.
Another option would be to define our own local "strict" flag for the
callbacks, and then have wrappers that translate that to IDENT_STRICT
where it matters. But that would be more boilerplate for little gain
(most functions would still ignore the "strict" flag anyway).

A long term (but rather minor) pet-peeve of mine was the name
ll-merge.[ch]. I thought it made it harder to realize what stuff was
related to merging when I was working on the merge machinery and trying
to improve it.
Further, back in d1cbe1e6d8a ("hash-ll.h: split out of hash.h to remove
dependency on repository.h", 2023-04-22), we have split the portions of
hash.h that do not depend upon repository.h into a "hash-ll.h" (due to
the recommendation to use "ll" for "low-level" in its name[1], but which
I used as a suffix precisely because of my distaste for "ll-merge").
When we discussed adding additional "*-ll.h" files, a request was made
that we use "ll" consistently as either a prefix or a suffix. Since it
is already in use as both a prefix and a suffix, the only way to do so
is to rename some files.
Besides my distaste for the ll-merge.[ch] name, let me also note that
the files
ll-fsmonitor.h, ll-hash.h, ll-merge.h, ll-object-store.h, ll-read-cache.h
would have essentially nothing to do with each other and make no sense
to group. But giving them the common "ll-" prefix would group them. Using
"-ll" as a suffix thus seems just much more logical to me. Rename
ll-merge.[ch] to merge-ll.[ch] to achieve this consistency, and to
ensure we get a more logical grouping of files.

The function add_files_to_cache() is used by all three of builtin/{add,
checkout, commit}.c. That suggests this is common library code, and
should be moved somewhere else, like read-cache.c. However, the
function and its helpers made use of two global variables that made
straight code movement difficult:
* the_index
* include_sparse
The latter was perhaps more problematic since it was only accessible in
builtin/add.c but was still affecting builtin/checkout.c and
builtin/commit.c without this fact being very clear from the code. I'm
not sure if the other two callers would want to add a `--sparse` flag
similar to add.c to get non-default behavior, but exposing this
dependence will help if we ever decide we do want to add such a flag.
Modify add_files_to_cache() and its helpers to accept the necessary

of the former file and into setup.c. A secondary issue that made it
difficult was the init_shared_repository global variable; replace it
with a simple parameter that is passed to the relevant functions.

This commit was prompted by a desire to move the functions which
builtin/init-db.c and builtin/clone.c share out of the former file and
into setup.c. One issue that made it difficult was the
init_is_bare_repository global variable.
init_is_bare_repository's sole use in life it to cache a value in
init_db(), and then be used in create_default_files(). This is a bit
odd since init_db() directly calls create_default_files(), and is the
only caller of that function. Convert the global to a simple function
parameter instead.
(Of course, this doesn't fix the fact that this value is then ignored by
create_default_files(), as noted in a big TODO comment in that function,
but it at least includes no behavioral change other than getting rid of
a very questionable global variable.)

The comments in create_default_files() talks about reading config from
the config file in the specified `--templates` directory, which leads to
the question of whether core.bare could be set in such a config file and
thus whether the code is doing the right thing. It turns out, that it
doesn't; it unconditionally ignores core.bare in the config file in any
--templates directory. It is not clear to me that fixing it can be done
within this function; it seems to occur too late:
* create_default_files() is called by init_db()
* init_db() is called by both builtin/{clone.c,init-db.c}
* both callers of init_db() call set_git_work_tree() before init_db()
and in order to actual affect whether a repository is bear, we'd need to
somewhere reset these values, not just the is_bare_repository_cfg
setting.
I do not want to open this can of worms at this time; I'm trying to
clean up some headers, for which I need to move some functions, for
which I need to clean up some globals, and that's far enough down the
rabbit hole. So, simply document the issue with a careful TODO comment
and a few testcases.

Sometimes, the user may want to add or append multiple notes
without any separator to be added between them.

This commit introduces a new option "--[no-]stripspace" to git notes
append, git notes edit, and git notes add. This option allows users to
control whether the note message need to stripped out.
For the consideration of backward compatibility, let's look at the
behavior about "stripspace" in "git notes" command:
1. "Edit Message" case: using the default editor to edit the note
message.
In "edit" case, the edited message will always be stripped out, the
implementation which can be found in the "prepare_note_data()". In
addition, the "-c" option supports to reuse an existing blob as a
note message, then open the editor to make a further edition on it,
the edited message will be stripped.
This commit doesn't change the default behavior of "edit" case by
using an enum "notes_stripspace", only when "--no-stripspace" option
is specified, the note message will not be stripped out. If you do
not specify the option or you specify "--stripspace", clearly, the
note message will be stripped out.
2. "Assign Message" case: using the "-m"/"-F"/"-C" option to specify the
note message.
In "assign" case, when specify message by "-m" or "-F", the message
will be stripped out by default, but when specify message by "-C",
the message will be copied verbatim, in other word, the message will
not be stripped out. One more thing need to note is "the order of
the options matter", that is, if you specify "-C" before "-m" or
"-F", the reused message by "-C" will be stripped out together,
because everytime concat "-m" or "-F" message, the concated message
will be stripped together. Oppositely, if you specify "-m" or "-F"
before "-C", the reused message by "-C" will not be stripped out.
This commit doesn't change the default behavior of "assign" case by
extending the "stripspace" field in "struct note_msg", so we can
distinguish the different behavior of "-m"/"-F" and "-C" options
when we need to parse and concat the message.

Rename "insert_separator" to "append_separator" and also remove the
"postion" argument, this serves two purpose:
The first is that when specifying more than one "-m" ( like "-F", etc)
to "git notes add" or "git notes append", the order of them matters,
which means we need to append the each separator and message in turn,
so we don't have to make the caller specify the position, the "append"
operation is enough and clear.
The second is that when we execute the "git notes append" subcommand,
we need to combine the "prev_note" and "current_note" to get the
final result. Before, we inserted a newline character at the beginning
of "current_note". Now, we will append a newline to the end of
"prev_note" instead, this will give the consisitent results.
