commit-reach: free temporary list in get_octopus_merge_bases()
t6700: mark test as leak-free
We call repo_get_merge_bases(), which allocates a commit_list, but never
free the result, causing a leak.
The obvious solution is to free it, but we need to look at the contents
of the first item to decide whether to leave the loop. One option is to
free it in both code paths. But since the commit that the list points to
is longer-lived than the list itself, we can just dereference it
immediately, free the list, and then continue with the existing logic.
This is about the same amount of code, but keeps the list management all
in one place.
This lets us mark a number of merge-related test scripts as leak-free.

Extract the commonly used initialization of the --stat-width=<width>,
--stat-name-width=<width> and --stat-graph-with=<width> parameters to their
internal default values into a helper function, to avoid repeating the same
initialization code in a few places.
Add a couple of tests to additionally cover existing configuration options
diff.statNameWidth=<width> and diff.statGraphWidth=<width> when used by
git-merge to generate --stat outputs. This closes the gap that existed
previously in the --stat tests, and reduces the chances for having any
regressions introduced by this commit.
While there, perform a small bunch of minor wording tweaks in the improved
unit test, to improve its test-level consistency a bit.

Add new configuration option diff.statNameWidth=<width> that is equivalent
to the command-line option --stat-name-width=<width>, but it is ignored
by format-patch. This follows the logic established by the already
existing configuration option diff.statGraphWidth=<width>.
Limiting the widths of names and graphs in the --stat output makes sense
for interactive work on wide terminals with many columns, hence the support
for these configuration options. They don't affect format-patch because
it already adheres to the traditional 80-column standard.
Update the documentation and add more tests to cover new configuration
option diff.statNameWidth=<width>. While there, perform a few minor code
and whitespace cleanups here and there, as spotted.

The option_parse_strategy() callback does not look at opt->value;
instead it calls append_strategy(), which manipulates the global
use_strategies array directly. But the OPT_CALLBACK declaration assigns
"&use_strategies" to opt->value.
One could argue this is good, as it tells the reader what we generally
expect the callback to do. But it is also bad, because it can mislead
you into thinking that swapping out "&use_strategies" there might have
any effect. Let's switch it to pass NULL (which is what every other
"does not bother to look at opt->value" callback does). If you want to
know what the callback does, it's easy to read the function itself.

The previous commit argued that parse-options callbacks should try to
use opt->value rather than touching globals directly. In some cases,
however, that's awkward to do. Some callbacks touch multiple variables,
or may even just call into an abstracted function that does so.
In some of these cases we _could_ convert them by stuffing the multiple
variables into a single struct and passing the struct pointer through
opt->value. But that may make other parts of the code less readable,
as the struct relationship has to be mentioned everywhere.
Let's just accept that these cases are special and leave them as-is. But
we do need to mark their "opt" parameters to satisfy -Wunused-parameter.

The "-n" option is implemented by an option callback, as it is really a
"reverse bool". If given, it sets show_diffstat to 0. In theory, when
negated, it would set the same flag to 1. But it's not possible to
trigger that, since short options cannot be negated.
So in practice this is really just a SET_INT to 0. Let's use that
instead, which shortens the code.
Note that negation here would do the wrong thing (as with any SET_INT
with a value of "0"). We could specify PARSE_OPT_NONEG to future-proof
ourselves against somebody adding a long option name (which would make
it possible to negate). But there's not much point:
1. Nobody is going to do that, because the negated form already
exists, and is called "--stat" (which is defined separately so that
"--no-stat" works).
2. If they did, the BUG() check added by 3284b93862 (parse-options:
disallow negating OPTION_SET_INT 0, 2023-08-08) will catch it (and
that check is smart enough to realize that our short-only option is
OK).

The "xopts" variable uses a custom array with ALLOC_GROW(). Using a
strvec simplifies things a bit. We need fewer variables, and we can also
ditch our custom parseopt callback in favor of OPT_STRVEC().
As a bonus, this means that "--no-strategy-option", which was previously
a silent noop, now does something useful: like other list-like options,
it will clear the list of -X options seen so far. This matches the
behavior of revert/cherry-pick, which made the same change in fb60b9f37f
(sequencer: use struct strvec to store merge strategy options,
2023-04-10).

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

The wrapping of some argument lists is likewise manual, as coccinelle
