Extending the previous step, this allows the whitespace placed after
the value before the "# comment message" to be tweaked by tweaking
the preprocessing rule to:
* If the given comment string begins with one or more whitespace
characters followed by '#', it is passed intact.
* If the given comment string begins with '#', a Space is
prepended.
* Otherwise, " # " (Space, '#', Space) is prefixed.
* A string with LF in it cannot be used as a comment string.
Unlike the previous step, which unconditionally added a space after
the value before writing the "# comment string", because the above
preprocessing already gives a whitespace before the '#', the
resulting string is written immediately after copying the value.
And the sanity checking rule becomes
* comment string after the above massaging that comes into
git_config_set_multivar_in_file_gently() must
- begin with zero or more whitespace characters followed by '#'.
- not have a LF in it.
I personally think this is over-engineered, but since I thought
things through anyway, here it is in the patch form. The logic to
tweak end-user supplied comment string is encapsulated in a new
helper function, git_config_prepare_comment_string(), so if new
front-end callers would want to use the same massaging rules, it is
easily reused.
Unfortunately I do not think of a way to tweak the preprocessing
rules further to optionally allow having no blank after the value,
i.e. to produce
[section]
variable = value#comment
(which is a valid way to say section.variable=value, by the way)
without sacrificing the ergonomics for the more usual case, so this
time I really stop here.

When git adds comments itself (like "rebase -i" todo list and
"commit -e" log message editor), it always gives a comment
introducer "#" followed by a Space before the message, except for
the recently introduced "git config --comment", where the users are
forced to say " this is my comment" if they want to add their
comment in this usual format; otherwise their comment string will
end up without a space after the "#".
Make it more ergonomic, while keeping it possible to also use this
unusual style, by massaging the comment string at the UI layer with
a set of simple rules:
* If the given comment string begins with '#', it is passed intact.
* Otherwise, "# " is prefixed.
* A string with LF in it cannot be used as a comment string.
Right now there is only one "front-end" that accepts end-user
comment string and calls the underlying machinery to add or modify
configuration file with comments, but to make sure that the future
callers perform similar massaging as they see fit, add a sanity
check logic in git_config_set_multivar_in_file_gently(), which is
the single choke point in the codepaths that consumes the comment
string.

Introduce the ability to append comments to modifications
made using git-config. Example usage:
git config --comment "changed via script" \
--add safe.directory /home/alice/repo.git
based on the proposed patch, the output produced is:
[safe]
directory = /home/alice/repo.git #changed via script
Users need to be able to distinguish between config entries made
using automation and entries made by a human. Automation can add
comments containing a URL pointing to explanations for the change
made, avoiding questions from users as to why their config file
was changed by a third party.
The implementation ensures that a # character is unconditionally
prepended to the provided comment string, and that the comment
text is appended as a suffix to the changed key-value-pair in the
same line of text. Multi-line comments (i.e. comments containing
linefeed) are rejected as errors, causing Git to exit without
making changes.
Comments are aimed at humans who inspect or change their Git
config using a pager or editor. Comments are not meant to be
read or displayed by git-config at a later time.

Rename format_trailer_info() to format_trailers(). Finally, both
interpret-trailers and format_trailers_from_commit() can call
"format_trailers()"!
Update the comment in <trailer.h> to remove the (now obsolete) caveats
about format_trailers_from_commit(). Those caveats come from
a388b10fc1 (pretty: move trailer formatting to trailer.c, 2017-08-15)
where it says:
pretty: move trailer formatting to trailer.c
The next commit will add many features to the %(trailer)
placeholder in pretty.c. We'll need to access some internal
functions of trailer.c for that, so our options are either:
1. expose those functions publicly
or
2. make an entry point into trailer.c to do the formatting
Doing (2) ends up exposing less surface area, though do note
that caveats in the docstring of the new function.
which suggests format_trailers_from_commit() started out from pretty.c
and did not have access to all of the trailer implementation internals,
and was never intended to replace (unify) the formatting machinery in
trailer.c. The refactors leading up to this commit (as well as
additional refactors that will follow) expose additional functions
publicly, and is therefore choosing option (1) as described in
a388b10fc1.

Now that the preparatory refactors are over, we can replace the call to
format_trailers() in interpret-trailers with format_trailer_info(). This
unifies the trailer formatting machinery
In order to avoid breakages in t7502 and t7513, we have to steal the
features present in format_trailers(). Namely, we have to teach
format_trailer_info() as follows:
(1) make it aware of opts->trim_empty, and
(2) make it avoid hardcoding ": " as the separator and space (which
can result in double-printing these characters).
For (2), make it only print the separator and space if we cannot find
any recognized separator somewhere in the key (yes, keys may have a
trailing separator in it --- we will eventually fix this design but not
now). Do so by copying the code out of print_tok_val(), and deleting the
same function.

This wraps up the preparatory refactors to unify the trailer formatters.
Two patches ago we made format_trailer_info() use trailer_item objects
instead of the "trailers" string array. The strings in the array
include trailing newlines, because the string array is split up with
trailer_lines = strbuf_split_buf(str + trailer_block_start,
end_of_log_message - trailer_block_start,
'\n',
0);
in trailer_info_get() and strbuf_split_buf() includes the terminator (in
this case the newline character '\n') for each split-up substring.
And before we made the transition to use trailer_item objects for it,
format_trailer_info() called parse_trailer() (which trims newlines) for
trailer lines but did _not_ call parse_trailer() for non-trailer lines.
So for trailer lines it had to add back the trimmed newline like this
if (!opts->separator)
strbuf_addch(out, '\n');
But for non-trailer lines it didn't have to add back the newline because
it could just reuse same string in the "trailers" string array (which
again, already included the trailing newline).
Now that format_trailer_info() uses trailer_item objects for all cases,
it can't rely on "trailers" string array anymore. And so it must be
taught to add a newline back when printing non-trailer lines, just like
it already does for trailer lines. Do so now.
The test suite can pass again without the need to hide failures
with *_failure, so flip the affected test cases back to *_success. Now,
format_trailer_info() is in better shape to supersede format_trailers(),
which we'll do in the next commit.

This is another preparatory refactor to unify the trailer formatters.
In the last patch we made format_trailer_info() use trailer_item objects
instead of the "trailers" string array. This means that the call to
unfold_value() here is redundant because the trailer_item objects are

caller, format_trailers_from_commit().

In git-restore we need to free the pathspec and pathspec_from_file
values from the struct checkout_opts.
A simple fix could be to free them in cmd_restore, after the call to

cmd_checkout.
However, we can do even better.
We have git-switch and git-restore, both of them spin-offs[3][4] of
git-checkout. All three are implemented as thin wrappers around
checkout_main. Considering this, it makes a lot of sense to do the
cleanup closer to checkout_main.
Move the cleanups, including the new_branch_info variable, to
checkout_main.
As a consequence, mark: t2070, t2071, t2072 and t6418 as leak-free.

When using "git checkout" to recreate merge conflicts or merge
uncommitted changes when switching branch "--conflict" sensibly implies
"--merge". Unfortunately the way this is implemented means that "git
checkout --conflict=diff3 --no-merge" implies "--merge" violating the
usual last-one-wins rule. Fix this by only overriding the value of
opts->merge if "--conflicts" comes after "--no-merge" or "-[-no]-merge"
is not given on the command line.
The behavior of "git checkout --merge --no-conflict" is unchanged and
will still merge on the basis that the "-[-no]-conflict" options are
primarily intended to affect the conflict style and so "--no-conflict"
should cancel a previous "--conflict" but not override "--merge".
Of the four new tests the second one tests the behavior change
introduced by this commit, the other three check that this commit does
not regress the existing behavior.

Passing an invalid conflict style name such as "--conflict=bad" gives
the error message
error: unknown style 'bad' given for 'merge.conflictstyle'
which is unfortunate as it talks about a config setting rather than
the option given on the command line. This happens because the
implementation calls git_xmerge_config() to set the conflict style
using the value given on the command line. Use the newly added
parse_conflict_style_name() instead and pass the value down the call
chain to override the config setting. This also means we can avoid
setting up a struct config_context required for calling
git_xmerge_config().
The option is now parsed in a callback to avoid having to store the
option name. This is a change in behavior as now
git checkout --conflict=bad --conflict=diff3
will error out when parsing "--conflict=bad" whereas before this change
it would succeed because it would only try to parse the value of the
last "--conflict" option given on the command line.

It was reported that git-clone(1) started to fail in Git v2.44 when
cloning via HTTPS when the config contains an "includeIf.*.onbranch"
condition:
$ git clone https://example.com/repo.git
Cloning into 'repo'...
BUG: refs.c:2083: reference backend is unknown
error: git-remote-https died of signal 6
This regression was bisected to 0fcc285c5e (refs: refactor logic to look
up storage backends, 2023-12-29). This commit tightens the logic to look
up ref backends such that we now die when the backend has not yet been
detected by reading the gitconfig.
Now on its own, this commit wouldn't have caused the failure. But in
18c9cb7524 (builtin/clone: create the refdb with the correct object
format, 2023-12-12) we have also changed how git-clone(1) initializes
the refdb such that it happens after the remote helper is spawned, which
is required so that we can first learn about the object format used by
the remote repository before initializing the refdb. Starting with this
change, the remote helper will be unable to detect the repository right
from the start and thus have an unconfigured ref backend. Consequently,
when we try to resolve the "includeIf.*.onbranch" condition, we will now
fail to look up the refdb and die.
This regression has already been fixed via 199f44cb2e (builtin/clone:
allow remote helpers to detect repo, 2024-02-27), where we now
pre-initialize a partial refdb so that the remote helper can detect the
repository right from the start. But it's clear that we're lacking test
coverage of this functionality.
Add a test to avoid regressing in the future. Note that this test stops
short of defining the desired behaviour for the "onbranch" condition
during a clone. It's not quite clear how exactly it should behave, so
this is a leftover bit for the future.

Now that all of the code handles multi-byte comment characters, it's
safe to allow users to set them.
There is one special case I kept: we still will not allow an empty
string for the commentChar. While it might make sense in some contexts
(e.g., output where you don't want any comment prefix), there are plenty
where it will behave badly (e.g., all of our starts_with() checks will
indicate that every line is a comment!). It might be reasonable to
assign some meaningful semantics, but it would probably involve checking
how each site behaves. In the interim let's forbid it and we can loosen
things later.
Likewise, the "commentChar cannot be a newline" rule is now extended to
"it cannot contain a newline" (for the same reason: it can confuse our
parsing loops).
Since comment_line_str is used in many parts of the code, it's hard to
cover all possibilities with tests. We can convert the existing
double-semicolon prefix test to show that "git status" works. And we'll
give it a more challenging case in t7507, where we confirm that
git-commit strips out the commit template along with any --verbose text
when reading the edited commit message back in. That covers the basics,
though it's possible there could be issues in more exotic spots (e.g.,
the sequencer todo list uses its own code).

entries in comment_line_str.

In wt_longstatus_print_tracking() we may conditionally show a comment
prefix based on the wt_status->display_comment_prefix flag. We handle
that by creating a local "comment_line_string" that is either the empty
string or the comment character followed by a space.
For a single-byte comment, the maximum length of this string is 2 (plus
a NUL byte). But to handle multi-byte comment characters, it can be
arbitrarily large. One way to handle this is to just call
xstrfmt("%s ", comment_line_str), and then free it when we're done.
But we can simplify things further by just conditionally switching
between our prefix string and an empty string when formatting. We
couldn't just do that with the previous code, because the comment
character was a single byte. There's no way to have a "%c" format switch
between some character and "no character at all". Whereas with "%s" you
can switch between some string and the empty string. So now that we have
a comment string and not a comment char, we can just use it directly
when formatting. Do note that we have to also conditionally add the
trailing space at the same time.

We already match multi-byte comment characters in parse_insn_line(),
thanks to the previous commit, yielding a TODO_COMMENT entry. But in
todo_list_to_strbuf(), we may call command_to_char() to convert that
back into something we can output.
We can't just return comment_line_char anymore, since it may require
multiple bytes. Instead, we'll return "0" for this case, which is the
same thing we'd return for a command which does not have a single-letter
abbreviation (e.g., "revert" or "noop"). There is only a single caller
of command_to_char(), and upon seeing "0" it falls back to outputting
the full name via command_to_string(). So we can handle TODO_COMMENT
there, returning the full string.
Note that there are many other callers of command_to_string(), which
will now behave differently if they pass TODO_COMMENT. But we would not
expect that to happen; prior to this commit, the function just calls
die() in this case. And looking at those callers, that makes sense;
e.g., do_pick_commit() will only be called when servicing a pick
command, and should never be called for a comment in the first place.
