a5bb10fd5e config: avoid fixed-sized buffer when renaming/deleting a section
When renaming (or deleting) a section of configuration, Git uses the
function `git_config_copy_or_rename_section_in_file()` to rewrite the
configuration file after applying the rename or deletion to the given
section.

To do this, Git repeatedly calls `fgets()` to read the existing
configuration data into a fixed size buffer.

When the configuration value under `old_name` exceeds the size of the
buffer, we will call `fgets()` an additional time even if there is no
newline in the configuration file, since our read length is capped at
`sizeof(buf)`.

If the first character of the buffer (after zero or more characters
satisfying `isspace()`) is a '[', Git will incorrectly treat it as
beginning a new section when the original section is being removed. In
other words, a configuration value satisfying this criteria can
incorrectly be considered as a new secftion instead of a variable in the
original section.

Avoid this issue by using a variable-width buffer in the form of a
strbuf rather than a fixed-with region on the stack. A couple of small
points worth noting:

  - Using a strbuf will cause us to allocate arbitrary sizes to match
    the length of each line.  In practice, we don't expect any
    reasonable configuration files to have lines that long, and a
    bandaid will be introduced in a later patch to ensure that this is
    the case.

  - We are using strbuf_getwholeline() here instead of strbuf_getline()
    in order to match `fgets()`'s behavior of leaving the trailing LF
    character on the buffer (as well as a trailing NUL).

    This could be changed later, but using strbuf_getwholeline() changes
    the least about this function's implementation, so it is picked as
    the safest path.

  - It is temping to want to replace the loop to skip over characters
    matching isspace() at the beginning of the buffer with a convenience
    function like `strbuf_ltrim()`. But this is the wrong approach for a
    couple of reasons:

    First, it involves a potentially large and expensive `memmove()`
    which we would like to avoid. Second, and more importantly, we also
    *do* want to preserve those spaces to avoid changing the output of
    other sections.

In all, this patch is a minimal replacement of the fixed-width buffer in
`git_config_copy_or_rename_section_in_file()` to instead use a `struct
strbuf`.

29198213c9 t1300: demonstrate failure when renaming sections with long lines
When renaming a configuration section which has an entry whose length
exceeds the size of our buffer in config.c's implementation of
`git_config_copy_or_rename_section_in_file()`, Git will incorrectly
form a new configuration section with part of the data in the section
being removed.

In this instance, our first configuration file looks something like:

    [b]
      c = d <spaces> [a] e = f
    [a]
      g = h

Here, we have two configuration values, "b.c", and "a.g". The value "[a]
e = f" belongs to the configuration value "b.c", and does not form its
own section.

However, when renaming the section 'a' to 'xyz', Git will write back
"[xyz]\ne = f", but "[xyz]" is still attached to the value of "b.c",
which is why "e = f" on its own line becomes a new entry called "b.e".

A slightly different example embeds the section being renamed within
another section.

Demonstrate this failure in a test in t1300, which we will fix in the
following commit.

9db05711c9 apply --reject: overwrite existing .rej symlink if it exists
The `git apply --reject` is expected to write out `.rej` files in case
one or more hunks fail to apply cleanly. Historically, the command
overwrites any existing `.rej` files. The idea being that
apply/reject/edit cycles are relatively common, and the generated `.rej`
files are not considered precious.

But the command does not overwrite existing `.rej` symbolic links, and
instead follows them. This is unsafe because the same patch could
potentially create such a symbolic link and point at arbitrary paths
outside the current worktree, and `git apply` would write the contents
of the `.rej` file into that location.

Therefore, let's make sure that any existing `.rej` file or symbolic
link is removed before writing it.

aabfdc9514 branch, for-each-ref, tag: add option to omit empty lines
If the given format string expands to the empty string, a newline is
still printed. This makes using the output linewise more tedious. For
example, git update-ref --stdin does not accept empty lines.

Add options to "git branch", "git for-each-ref", and "git tag" to
not print these empty lines.  The default behavior remains the same.

4e33535ea9 clone: error specifically with --local and symlinked objects
6f054f9fb3 (builtin/clone.c: disallow --local clones with
symlinks, 2022-07-28) gives a good error message when "git clone
--local" fails when the repo to clone has symlinks in
"$GIT_DIR/objects". In bffc762f87 (dir-iterator: prevent top-level
symlinks without FOLLOW_SYMLINKS, 2023-01-24), we later extended this
restriction to the case where "$GIT_DIR/objects" is itself a symlink,
but we didn't update the error message then - bffc762f87's tests show
that we print a generic "failed to start iterator over" message.

This is exacerbated by the fact that Documentation/git-clone.txt
mentions neither restriction, so users are left wondering if this is
intentional behavior or not.

Fix this by adding a check to builtin/clone.c: when doing a local clone,
perform an extra check to see if "$GIT_DIR/objects" is a symlink, and if
so, assume that that was the reason for the failure and report the
relevant information. Ideally, dir_iterator_begin() would tell us that
the real failure reason is the presence of the symlink, but (as far as I
can tell) there isn't an appropriate errno value for that.

Also, update Documentation/git-clone.txt to reflect that this
restriction exists.

fd72637423 t2024: fix loose/strict local base branch DWIM test
Test 'loosely defined local base branch is reported correctly' in
t2024-checkout-dwim.sh, which was introduced in [1] compares output of
two invocations of "git checkout", invoked with two different branches
named "strict" and "loose".  As per description in [1], the test is
validating that output of tracking information for these two branches.
This tracking information is printed to standard output:

    Your branch is behind 'main' by 1 commit, and can be fast-forwarded.
      (use "git pull" to update your local branch)

The test assumes that the names of the two branches (strict and loose)
are in that output, and pipes the output through sed to replace names of
the branches with "BRANCHNAME".  Command "git checkout", however,
outputs the branch name to standard error, not standard output -- see
message "Switched to branch '%s'\n" in function "update_refs_for_switch"
in "builtin/checkout.c".  This means that the two invocations of sed do
nothing.

Redirect both the standard output and the standard error of "git
checkout" for these assertions.  Ensure that compared files have the
string "BRANCHNAME".

In a series of piped commands, only the return code of the last command
is used.  Thus, all other commands will have their return codes masked.
Avoid piping of output of git directly into sed to preserve the exit
status code of "git checkout", while we're here.

    defined branch.*.merge, 2014-10-14)

05106aa198 rebase: remove a couple of redundant strategy tests
Remove a test in t3402 that has been redundant ever since 80ff47957b
(rebase: remember strategy and strategy options, 2011-02-06).  That
commit added a new test, the first part of which (as noted in the old
commit message) duplicated an existing test.

Also remove a test t3418 that has been redundant since the merge backend
was removed in 68aa495b59 (rebase: implement --merge via the interactive
machinery, 2018-12-11), since it now tests the same code paths as the
preceding test.

4960e5c7bd rebase -m: fix serialization of strategy options
To store the strategy options rebase prepends " --" to each one and
writes them to a file. To load them it reads the file and passes the
contents to split_cmdline(). This roughly mimics the behavior of the
scripted rebase but has a couple of limitations, (1) options containing
whitespace are not properly preserved (this is true of the scripted
rebase as well) and (2) options containing '"' or '\' are incorrectly
parsed and may cause the parser to return an error.

Fix these limitations by quoting each option when they are stored so
that they can be parsed correctly. Now that "--preserve-merges" no
longer exist this change also stops prepending "--" to the options when
they are stored as that was an artifact of the scripted rebase.

These changes are backwards compatible so the files written by an older
version of git can still be read. They are also forwards compatible,
the file can still be parsed by recent versions of git as they treat the
"--" prefix as optional.

4a8bc9860a rebase -m: cleanup --strategy-option handling
When handling "--strategy-option" rebase collects the commands into a
struct string_list, then concatenates them into a string, prepending "--"
to each one before splitting the string and removing the "--" prefix.
This is an artifact of the scripted rebase and the need to support
"rebase --preserve-merges". Now that "--preserve-merges" no-longer
exists we can cleanup the way the argument is handled.

The tests for a bad strategy option are adjusted now that
parse_strategy_opts() is no-longer called when starting a rebase. The
fact that it only errors out when running "git rebase --continue" is a
mixed blessing but the next commit will fix the root cause of the
parsing problem so lets not worry about that here.

be39144954 userdiff: support regexec(3) with multi-byte support
Since 1819ad327b (grep: fix multibyte regex handling under macOS,
2022-08-26) we use the system library for all regular expression
matching on macOS, not just for git grep.  It supports multi-byte
strings and rejects invalid multi-byte characters.

This broke all built-in userdiff word regexes in UTF-8 locales because
they all include such invalid bytes in expressions that are intended to
match multi-byte characters without explicit support for that from the
regex engine.

"|[^[:space:]]|[\xc0-\xff][\x80-\xbf]+" is added to all built-in word
regexes to match a single non-space or multi-byte character.  The \xNN
characters are invalid if interpreted as UTF-8 because they have their
high bit set, which indicates they are part of a multi-byte character,
but they are surrounded by single-byte characters.

Replace that expression with "|[^[:space:]]" if the regex engine
supports multi-byte matching, as there is no need to have an explicit
range for multi-byte characters then.  Check for that capability at
runtime, because it depends on the locale and thus on environment
variables.  Construct the full replacement expression at build time
and just switch it in if necessary to avoid string manipulation and
allocations at runtime.

Additionally the word regex for tex contains the expression
"[a-zA-Z0-9\x80-\xff]+" with a similarly invalid range.  The best
replacement with only valid characters that I can come up with is
"([a-zA-Z0-9]|[^\x01-\x7f])+".  Unlike the original it matches NUL
characters, though.  Assuming that tex files usually don't contain NUL
this should be acceptable.
