brian m. carlson ed773a18c6 var: add config file locations
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.

brian m. carlson 576a37fccb var: add attributes files locations
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.

brian m. carlson cdd489eaf9 var: adjust memory allocation for strings
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
of our functions allocate its own memory and make the caller responsible
for freeing it.

Right now, we have only two items in our variable struct.  However, in
the future, we're going to add two more items.  To help keep our diffs

brian m. carlson 1e65721227 var: add support for listing the shell
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.

Jeff King 4db16f58c7 var: mark unused parameters in git_var callbacks
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).

Elijah Newren 6723899932 merge-ll: rename from ll-merge
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 d1cbe1e6d8 ("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.

Elijah Newren 50c37ee839 add: modify add_files_to_cache() to avoid globals
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
arguments instead of relying on globals.

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.)

Elijah Newren 0f7443bdc7 init-db: document existing bug with core.bare in template config
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.

Teng Long 3d6a316464 notes: introduce "--no-separator" option
Sometimes, the user may want to add or append multiple notes
without any separator to be added between them.

Teng Long c4e2aa7d45 notes.c: introduce "--[no-]stripspace" option
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.

Teng Long b7d87ad537 notes.c: append separator instead of insert by pos
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.

Teng Long 90bc19b3ae notes.c: introduce '--separator=<paragraph-break>' option
When adding new notes or appending to an existing notes, we will
insert a blank line between the paragraphs, like:

     $ git notes add -m foo -m bar
     $ git notes show HEAD
     foo

     bar

The default behavour sometimes is not enough, the user may want
to use a custom delimiter between paragraphs, like when
specifying '-m', '-F', '-C', '-c' options. So this commit
introduce a new '--separator' option for 'git notes add' and
'git notes append', for example when executing:

    $ git notes add -m foo -m bar --separator="-"
    $ git notes show HEAD
    foo
    -
    bar

a newline is added to the value given to --separator if it
does not end with one already. So when executing:

      $ git notes add -m foo -m bar --separator="-"
and
      $ export LF="
      "
      $ git notes add -m foo -m bar --separator="-$LF"

Both the two exections produce the same result.

The reason we use a "strbuf" array to concat but not "string_list", is
that the binary file content may contain '\0' in the middle, this will
cause the corrupt result if using a string to save.

Teng Long ef48fcc432 notes.c: cleanup 'strbuf_grow' call in 'append_edit'
Let's cleanup the unnecessary 'strbuf_grow' call in 'append_edit'. This
"strbuf_grow(&d.buf, size + 1);" is prepared for insert a blank line if
needed, but actually when inserting, "strbuf_insertstr(&d.buf, 0,
"\n");" will do the "grow" for us.

348f199b (builtin-notes: Refactor handling of -F option to allow
combining -m and -F, 2010-02-13) added these to mimic the code
introduced by 2347fae5 (builtin-notes: Add "append" subcommand for
appending to note objects, 2010-02-13) that reads in previous note
before the message.  And the resulting code with explicit sizing is
carried to this day.

In the context of reading an existing note in, exact sizing may have
made sense, but because the resulting note needs cleansing with
stripspace() when appending with this option, such an exact sizing
does not buy us all that much in practice.

It may help avoiding overallocation due to ALLOC_GROW() slop, but
nobody can feed so many long messages for it to matter from the
command line.

The value of config.worktree is per-repository, but has been kept
in a singleton global variable per process. This has been OK as
most Git operations interacted with a single repository at a time,

The global variable has been eliminated and made into a member in
the per-repository data structure.
