Junio C Hamano a89fa2fff2 Merge branch 'jk/color-variable-fixes'
Some places in the code confused a variable that is *not* a boolean
to enable color but is an enum that records what the user requested
to do about color.  A couple of bugs of this sort have been fixed,
while the code has been cleaned up to prevent similar bugs in the
future.

* jk/color-variable-fixes:
  config: store want_color() result in a separate bool
  add-interactive: retain colorbool values longer
  color: return bool from want_color()
  color: use git_colorbool enum type to store colorbools
  pretty: use format_commit_context.auto_color as colorbool
  diff: stop passing ecbdata->use_color as boolean
  diff: pass o->use_color directly to fill_metainfo()
  diff: don't use diff_options.use_color as a strict bool
  diff: simplify color_moved check when flushing
  grep: don't treat grep_opt.color as a strict bool
  color: return enum from git_config_colorbool()

Jeff King e9330ae4b8 color: use git_colorbool enum type to store colorbools
We traditionally used "int" to store and pass around the values defined
by "enum git_colorbool" (which were originally just #define macros).
Using an int doesn't produce incorrect results, but using the actual
enum makes the intent of the code more clear.

It would be nice if the compiler could catch cases where we used the
enum and an int interchangeably, since it's very easy to accidentally
check the boolean true/false of a colorbool like:

  if (branch_use_color)

This is wrong because GIT_COLOR_UNKNOWN and GIT_COLOR_AUTO evaluate to
true in C, even though we may ultimately decide not to use color. But C
is pretty happy to convert between ints and enums (even with various
-Wenum-* warnings). So this sadly doesn't protect us from such mistakes,
but it hopefully does make the code easier to read.

Jeff King 3c3e9b8303 color: use GIT_COLOR_* instead of numeric constants
Long ago Git's decision to show color for a subsytem was stored in a
tri-state variable: it could be true (1), false (0), or unknown (-1).
But since daa0c3d971 (color: delay auto-color decision until point of
use, 2011-08-17) we want to carry around a new state, "auto", which
bases the decision on the tty-ness of stdout (rather than collapsing
that "auto" state to a true/false immediately).

That commit introduced a set of GIT_COLOR_* defines to represent each
state: UNKNOWN, ALWAYS, NEVER, and AUTO. But it only used the AUTO
value, and left alone code using bare 0/1/-1 values. And of course since
then we've grown many new spots that use those bare values.

Let's switch all of these to use the named constants. That should make
the code a bit easier to read, as it is more obvious that we're
representing a color decision.

Phillip Wood a0e6aaea7d config: warn on core.commentString=auto
As support for this setting was deprecated in the last commit print a
warning (or die when WITH_BREAKING_CHANGES is enabled) if it is set.
Avoid bombarding the user with warnings by only printing it (a) when
running commands that call "git commit" and (b) only once per command.

Some scaffolding is added to repo_read_config() to allow it to
detect deprecated config settings and warn about them. As both
"core.commentChar" and "core.commentString" set the comment
character we record which one of them is used and tailor the
warning message appropriately.

Note the odd combination of die_message() followed by die(NULL)
is to allow the next commit to insert a call to advise() in the middle.

Phillip Wood fdae4114a6 breaking-changes: deprecate support for core.commentString=auto
When "core.commentString" is set to "auto" then "git commit" will
automatically select the comment character ensuring that it is not the
first character on any of the lines in the commit message. This was
introduced by commit 84c9dc2c5a (commit: allow core.commentChar=auto
for character auto selection, 2014-05-17). The motivation seems to be
to avoid commenting out lines from the existing message when amending
a commit that was created with a message from a file.

Unfortunately this feature does not work with:

 * commit message templates that contain comments.

 * prepare-commit-msg hooks that introduce comments.

 * "git commit --cleanup=strip --edit -F <file>" which means that it
   is incompatible with

   - the "fixup" and "squash" commands of "git rebase -i" as the
     comments added by those commands are then treated as part of
     the commit message.

   - the conflict comments added to the commit message by "git
     cherry-pick", "git rebase" etc. as these comments are then
     treated as part of the commit message.

It is also ignored by "git notes" when amending a note.

The issues with comments coming from a template, hook or file are a
consequence of the design of this feature and are therefore hard to
fix.

As the costs of this feature outweigh the benefits, deprecate it and
remove it in Git 3.0. If someone comes up with some patches that fix
all the issues in a maintainable way then I'd be happy to see this
change reverted.

The next commits will add a warning and some advice for users on how
they can update their config settings.

Leon Michalak 2b3ae04011 add-patch: add diff.context command line overrides
This patch compliments the previous commit, where builtins that use
add-patch infrastructure now respect diff.context and
diff.interHunkContext file configurations.

In particular, this patch helps users who don't want to set persistent
context configurations or just want a way to override them on a one-time
basis, by allowing the relevant builtins to accept corresponding command
line options that override the file configurations.

This mimics commands such as diff and log, which allow for both context
file configuration and command line overrides.

Patrick Steinhardt 9ce196e86b config: drop `git_config()` wrapper
In 036876a106 (config: hide functions using `the_repository` by
default, 2024-08-13) we have moved around a bunch of functions in the
config subsystem that depend on `the_repository`. Those function have
been converted into mere wrappers around their equivalent function that
takes in a repository as parameter, and the intent was that we'll
eventually remove those wrappers to make the dependency on the global
repository variable explicit at the callsite.

Follow through with that intent and remove `git_config()`. All callsites
are adjusted so that they use `repo_config(the_repository, ...)`
instead. While some callsites might already have a repository available,
this mechanical conversion is the exact same as the current situation
and thus cannot cause any regression. Those sites should eventually be
cleaned up in a later patch series.

Ayush Chandekar e69bbfa294 commit: avoid scanning trailing comments when 'core.commentChar' is "auto"
When core.commentChar is set to "auto", Git selects a comment character
by scanning the commit message contents and avoiding any character
already present in the message.

If the message still contains old conflict comments (starting with a
comment character), Git assumes that character is in use and chooses a
different one. As a result, those existing comment lines are no longer
recognized as comments and end up being included in the final commit
message.

To avoid this, skip scanning the trailing comment block when selecting
the comment character. This allows Git to safely reuse the original
character when appropriate, keeping the commit message clean and free of
leftover conflict information.

Background:

The "auto" value for core.commentchar was introduced in the commit
84c9dc2c5a (commit: allow core.commentChar=auto for character auto
selection, 2014-05-17) but did not exhibit this issue at that time.

The bug was introduced in commit a6c2654f83 (rebase -m: fix --signoff
with conflicts, 2024-04-18) where Git started writing conflict comments
to the file at 'rebase_path_message()'.

Johannes Schindelin 131a8fa815 commit: simplify code
The difference of two unsigned integers is defined to be unsigned, and
therefore it is misleading to check whether it is greater than zero
(instead, the more natural way would be to check whether the difference
is zero or not).

Let's instead avoid the subtraction altogether, and compare the two
operands directly, which makes the code more obvious as a side effect.

Patrick Steinhardt d012ceb5f3 global: use designated initializers for options
While we expose macros for most of our different option types understood
by the "parse-options" subsystem, not every combination of fields that
has one as that would otherwise quickly lead to an explosion of macros.
Instead, we just initialize structures manually for those variants of
fields that don't have a macro.

Callsites that open-code these structure initialization don't use
designated initializers though and instead just provide values for each
of the fields that they want to initialize. This has three significant
downsides:

  - Callsites need to specify all values up to the last field that they
    care about. This often includes fields that should simply be left at
    their default zero-initialized state, which adds distraction.

  - Any reader not deeply familiar with the layout of the structure
    has a hard time figuring out what the respective initializers mean.

  - Reordering or introducing new fields in the middle of the structure
    is impossible without adapting all callsites.

Convert all sites to instead use designated initializers, which we have
started using in our codebase quite a while ago. This allows us to skip
any default-initialized fields, gives the reader context by specifying
the field names and allows us to reorder or introduce new fields where
we want to.

Patrick Steinhardt 88dd321cfe path: drop `git_path()` in favor of `repo_git_path()`
Remove `git_path()` in favor of the `repo_git_path()` family of
functions, which makes the implicit dependency on `the_repository` go
away.

Note that `git_path()` returned a string allocated via `get_pathname()`,
which uses a rotating set of statically allocated buffers. Consequently,
callers didn't have to free the returned string. The same isn't true for
`repo_common_path()`, so we also have to add logic to free the returned
strings.

This refactoring also allows us to remove `repo_common_pathv()` as well
as `get_pathname()` from the public interface.

Patrick Steinhardt 648abbe22d config: fix leaking comment character config
When the comment line character has been specified multiple times in the
configuration, then `git_default_core_config()` will cause a memory leak
because it unconditionally copies the string into `comment_line_str`
without free'ing the previous value. In fact, it can't easily free the
value in the first place because it may contain a string constant.

Refactor the code such that we track allocated comment character strings
via a separate non-constant variable `comment_line_str_to_free`. Adapt
sites that set `comment_line_str` to set both and free the old value
that was stored in `comment_line_str_to_free`.

This memory leak is being hit in t3404. As there are still other memory
leaks in that file we cannot yet mark it as passing with leak checking

Patrick Steinhardt 63c9bd372e commit: fix leaking parents when calling `commit_tree_extended()`
When creating commits via `commit_tree_extended()`, the caller passes in
a string list of parents. This call implicitly transfers ownership of
that list to the function, which is quite surprising to begin with. But
to make matters worse, `commit_tree_extended()` doesn't even bother to
free the list of parents in error cases. The result is a memory leak,
and one that the caller cannot fix by themselves because they do not
know whether parts of the string list have already been released.

Refactor the code such that callers can keep ownership of the list of
parents, which is getting indicated by parameter being a constant
pointer now. Free the lists at the calling site and add a common exit
path to those sites as required.

string constants to `const char[]`. Fix various sites where we assign
such constants to non-const variables.

Patrick Steinhardt 1b261c20ed config: clarify memory ownership in `git_config_string()`
The out parameter of `git_config_string()` is a `const char **` even
though we transfer ownership of memory to the caller. This is quite
misleading and has led to many memory leaks all over the place. Adapt
the parameter to instead be `char **`.

John Passaro 4a8618785e builtin/commit: refactor --trailer logic
git-commit adds user trailers to the commit message by passing its
`--trailer` arguments to a child process running `git-interpret-trailers
--in-place`. This logic is broadly useful, not just for git-commit but
for other commands constructing message bodies (e.g. git-tag).

Let's move this logic from git-commit to a new function in the trailer
API, so that it can be re-used in other commands.

John Passaro 56740f9910 builtin/commit: use ARGV macro to collect trailers
Replace git-commit's callback for --trailer with the standard
OPT_PASSTHRU_ARGV macro. The callback only adds its values to a strvec
and sanity-checks that `unset` is always false; both of these are
already implemented in the parse-option API.

Ghanshyam Thakkar ac5946e624 builtin/commit: error out when passing untracked path with -i
When we provide a pathspec which does not match any tracked path
alongside --include, we do not error like without --include. If there
is something staged, it will commit the staged changes and ignore the
pathspec which does not match any tracked path. And if nothing is
staged, it will print the status. Exit code is 0 in both cases (unlike
without --include). This is also described in the TODO comment before
the relevant testcase.

Fix this by passing a character array to add_files_to_cache() to
collect the pathspec matching information and error out if the given
path is untracked. Also, amend the testcase to check for the error
message and remove the TODO comment.

Junio C Hamano 86829f3f3e revision: optionally record matches with pathspec elements
Unlike "git add" and other end-user facing commands, where it is
diagnosed as an error to give a pathspec with an element that does
not match any path, the diff machinery does not care if some
elements of the pathspec do not match.  Given that the diff
machinery is heavily used in pathspec-limited "git log" machinery,
and it is common for a path to come and go while traversing the
project history, this is usually a good thing.

However, in some cases we would want to know if all the pathspec
elements matched.  For example, "git add -u <pathspec>" internally
uses the machinery used by "git diff-files" to decide contents from
what paths to add to the index, and as an end-user facing command,
"git add -u" would want to report an unmatched pathspec element.

Add a new .ps_matched member next to the .prune_data member in
"struct rev_info" so that we can optionally keep track of the use of
.prune_data pathspec elements that can be inspected by the caller.

It is natural to expect that the "--untracked" option and the
status.showuntrackedFiles configuration variable to take a Boolean
value ("do you want me to show untracked files?"), but the current
code takes nothing but "no" as "no, please do not show any".

Allow the usual Boolean values to be given, and treat 'true' as
"normal", and 'false' as "no".

Junio C Hamano 63acdc4827 status: unify parsing of --untracked= and status.showUntrackedFiles
There are two code paths that take a string and parse it to enum
untracked_status_type.  Introduce a helper function and use it.

As these two places handle an error differently, add an additional
invalid value to the enum, and have the caller of the helper handle
the error condition, instead of dying or emitting error message from
the helper.

Jeff King f99e1d94f5 prefer comment_line_str to comment_line_char for printing
As part of our transition to multi-byte comment characters, we should
use the string variable rather than the historical character variable.
All of the sites adjusted here are just swapping out "%c" for "%s" in
format strings, or strbuf_addch() for strbuf_addstr(). The type system
and printf-attribute give the compiler enough information to make sure
our formats and variable changes all match (especially important for
cases where the format string is defined far away from its use, like
prepare_to_commit() in commit.c).
