Elijah Newren 90cbae9ce5 statinfo: move stat_{data,validity} functions from cache/read-cache
These functions do not depend upon struct cache_entry or struct
index_state in any way, and it seems more logical to break them out into
this file, especially since statinfo.h already has the struct stat_data
declaration.

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.

Elijah Newren fc81735057 init-db, clone: change unnecessary global into passed parameter
Much like the parent commit, 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.  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.

Elijah Newren c2f76965d0 init-db: remove unnecessary global variable
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.)

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 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.

Derrick Stolee 0dd1324a73 packfile: delete .idx files before .pack files
When installing a packfile, we place the .pack file before the .idx
file. The intention is that Git scans for .idx files in the pack
directory and then loads the .pack files from that list.

However, when we delete packfiles, we do not do this in the reverse
order as we should. The unlink_pack_path() method deletes the .pack
followed by the .idx.

This creates a window where the process could be interrupted between
the .pack deletion and the .idx deletion, leaving the repository in a
state that looks strange, but isn't actually too problematic if we
assume the pack was safe to delete. The .idx without a .pack will cause
some overhead, but will not interrupt other Git processes.

This ordering was introduced into the 'git repack' builtin by
a1bbc6c017 (repack: rewrite the shell script in C, 2013-09-15), though
we must be careful to track history through the code move in 8434e85d5f
(repack: refactor pack deletion for future use, 2019-06-10) to see that.

This became more important after 73320e49ad (builtin/repack.c: only
collect fully-formed packs, 2023-06-07) changed how 'git repack' scanned
for packfiles for use in the cruft pack process. It previously looked
for .pack files, but that was problematic due to the order that packs
are installed: repacks between the creation of a .pack and the creation
of its .idx would result in hard failures.

There is an independent proposal about what to do in the case of a .idx
without a .pack during this 'git repack' scenario, but this change is
focused on deleting .pack files more safely.

Modify the order to delete the .idx before the .pack. The rest of the
modifiers on the .pack should still come after the .pack so we know all
of the presumed properties of the packfile as long as it exists in the
filesystem, in case we wish to reinstate it by re-indexing the .pack
file.

René Scharfe 39dbd49b41 replace strbuf_expand_dict_cb() with strbuf_expand_step()
Avoid the overhead of setting up a dictionary and passing it via
strbuf_expand() to strbuf_expand_dict_cb() by using strbuf_expand_step()
in a loop instead.  It requires explicit handling of %% and unrecognized
placeholders, but is more direct and simpler overall, and expands only
on demand.

Jeff King db30130165 http: handle both "h2" and "h2h3" in curl info lines
When redacting auth tokens in trace output from curl, we look for http/2
headers of the form "h2h3 [header: value]". This comes from b637a41ebe
(http: redact curl h2h3 headers in info, 2022-11-11).

But the "h2h3" prefix changed to just "h2" in curl's fc2f1e547 (http2:
support HTTP/2 to forward proxies, non-tunneling, 2023-04-14). That's in
released version curl 8.1.0; linking against that version means we'll
fail to correctly redact the trace. Our t5559.17 notices and fails.

We can fix this by matching either prefix, which should handle both old
and new versions.

Rubén Justo 5e786ed3ee config: fix a leak in git_config_copy_or_rename_section_in_file
A branch can have its configuration spread over several configuration
sections.  This situation was already foreseen in 52d59cc645 (branch:
add a --copy (-c) option to go with --move (-m), 2017-06-18) when
"branch -c" was introduced.

Unfortunately, a leak was also introduced:

   $ git branch foo
   $ cat >> .git/config <<EOF
   [branch "foo"]
   	some-key-a = a value
   [branch "foo"]
   	some-key-b = b value
   [branch "foo"]
   	some-key-c = c value
   EOF
   $ git branch -c foo bar

   Direct leak of 130 byte(s) in 2 object(s) allocated from:

Rubén Justo 2935a97836 branch: fix a leak in cmd_branch
In 98e7ab6d42 (for-each-ref: delay parsing of --sort=<atom> options,
2021-10-20) a new string_list was introduced to accumulate any
"branch.sort" setting.

That string_list is cleared in ref_sorting_options(), which is only
called when processing the "--list" sub-command.  Therefore, with other
sub-command, while having any sort option set, a leak is produced, e.g.:

   $ git config branch.sort invalid_sort_option
   $ git branch --edit-description

   Direct leak of 384 byte(s) in 1 object(s) allocated from:
       ... in xrealloc wrapper.c
       ... in string_list_append_nodup string-list.c
       ... in string_list_append string-list.c
       ... in git_branch_config builtin/branch.c
       ... in configset_iter config.c
       ... in repo_config config.c
       ... in git_config config.c
       ... in cmd_branch builtin/branch.c
       ... in run_builtin git.c

   Indirect leak of 20 byte(s) in 1 object(s) allocated from:
       ... in xstrdup wrapper.c
       ... in string_list_append string-list.c
       ... in git_branch_config builtin/branch.c
       ... in configset_iter config.c
       ... in repo_config config.c
       ... in git_config config.c
       ... in cmd_branch builtin/branch.c
       ... in run_builtin git.c

We don't have a common clean-up section in cmd_branch().  To avoid
refactoring, keep the fix simple, and while we find a better solution
which hopefuly will avoid entirely that string_list, when no sort
options are needed; let's squelch the leak sanitizer using UNLEAK().

In bdaf1dfae7 (branch: new autosetupmerge option "simple" for matching
branches, 2022-04-29) a new exit for setup_tracking() missed the
clean-up, producing a leak.

   $ git config branch.autoSetupMerge simple

   $ git branch bar local/foo

Rubén Justo 05e717d556 rev-parse: fix a leak with --abbrev-ref
To handle "--abbrev-ref" we use shorten_unambiguous_ref().  This
function takes a refname and returns a shortened refname, which is a
newly allocated string that needs to be freed.

Unfortunately, the refname variable is reused to receive the shortened
one.  Therefore, we lose the original refname, which needs to be freed
as well, producing a leak.

This leak can be reviewed with:

   $ for a in {1..10}; do git branch foo_${a}; done
   $ git rev-parse --abbrev-ref refs/heads/foo_{1..10}

   Direct leak of 171 byte(s) in 10 object(s) allocated from:
       ... in xstrdup wrapper.c
       ... in expand_ref refs.c
       ... in repo_dwim_ref refs.c
       ... in show_rev builtin/rev-parse.c
       ... in cmd_rev_parse builtin/rev-parse.c
       ... in run_builtin git.c

We have this leak since a45d34691e (rev-parse: --abbrev-ref option to
shorten ref name, 2009-04-13) when "--abbrev-ref" was introduced.

Let's fix it.

Jeff King be3d654343 commit: pass --no-divider to interpret-trailers
When git-commit sees any "--trailer" options, it passes the
COMMIT_EDITMSG file through git-interpret-trailers. But it does so
without passing --no-divider, which means that interpret-trailers will
look for a "---" divider to signal the end of the commit message.

That behavior doesn't make any sense in this context; we know we have a
complete and solitary commit message, not something we have to further
parse. And as a result, we'll do the wrong thing if the commit message
contains a "---" marker (which otherwise is not syntactically
significant), inserting any new trailers at the wrong spot.

We can fix this by passing --no-divider. This is the exact situation for
which it was added in 1688c9a489 (interpret-trailers: allow suppressing
"---" divider, 2018-08-22). As noted in the message for that commit, it
just adds the mechanism, and further patches were needed to trigger it
from various callers.  We did that back then in a few spots, like
ffce7f590f (sequencer: ignore "---" divider when parsing trailers,
2018-08-22), but obviously missed this one.

Glen Choo 69f4da8ead setup.c: don't setup in discover_git_directory()
discover_git_directory() started modifying the_repository in ebaf3bcf1a
(repository: move global r_f_p_c to repo struct, 2021-06-17), when, in
the repository setup process, we started copying members from the
"struct repository_format" we're inspecting to the appropriate "struct
repository". However, discover_git_directory() isn't actually used in
the setup process (its only caller in the Git binary is
read_early_config()), so it shouldn't be doing this setup at all!

As explained by 16ac8b8db6 (setup: introduce the
discover_git_directory() function, 2017-03-13) and the comment on its
declaration, discover_git_directory() is intended to be an entrypoint
into setup.c machinery that allows the Git directory to be discovered
without side effects, e.g. so that read_early_config() can read
".git/config" before the_repository has been set up.

Fortunately, we didn't start to rely on this unintended behavior between
then and now, so we let's just remove it. It isn't harming anyone, but
it's confusing.
