All builtins receive a "prefix" parameter, but it is only useful if they
need to adjust filenames given by the user on the command line. For
builtins that do not even call parse_options(), they often don't look at
the prefix at all, and -Wunused-parameter complains.
Let's annotate those to silence the compiler warning. I gave a quick
scan of each of these cases, and it seems like they don't have anything
they _should_ be using the prefix for (i.e., there is no hidden bug that
we are missing). The only questionable cases I saw were:
- in git-unpack-file, we create a tempfile which will always be at the
root of the repository, even if the command is run from a subdir.
Arguably this should be created in the subdir from which we're run
(as we report the path only as a relative name). However, nobody has
complained, and I'm hesitant to change something that is deep
plumbing going back to April 2005 (though I think within our
scripts, the sole caller in git-merge-one-file would be OK, as it
moves to the toplevel itself).
- in fetch-pack, local-filesystem remotes are taken as relative to the
project root, not the current directory. So:
git init server.git
[...put stuff in server.git...]
git init client.git
cd client.git
mkdir subdir
cd subdir
git fetch-pack ../../server.git ...
won't work, as we quietly move to the top of the repository before
interpreting the path (so "../server.git" would work). This is
weird, but again, nobody has complained and this is how it has
always worked. And this is how "git fetch" works, too. Plus it
raises questions about how a configured remote like:
git config remote.origin.url ../server.git
should behave. I can certainly come up with a reasonable set of
behavior, but it may not be worth stirring up complications in a
plumbing tool.
So I've left the behavior untouched in both of those cases. If anybody
really wants to revisit them, it's easy enough to drop the UNUSED
marker. This commit is just about removing them as obstacles to turning
on -Wunused-parameter all the time.

Apply "index-compatibility.pending.cocci" rule to "builtin/*", but
exclude those where we conflict with in-flight changes.
As a result some of them end up using only "the_index", so let's have
them use the more narrow "USE_THE_INDEX_VARIABLE" rather than
"USE_THE_INDEX_COMPATIBILITY_MACROS".
Manual changes not made by coccinelle, that were squashed in:
* Whitespace-wrap argument lists for repo_hold_locked_index(),
repo_read_index_preload() and repo_refresh_and_write_index(), in cases
where the line became too long after the transformation.
* Change "refresh_cache()" to "refresh_index()" in a comment in
"builtin/update-index.c".
* For those whose call was followed by perror("<macro-name>"), change
it to perror("<function-name>"), referring to the new function.

Mostly apply the part of "index-compatibility.pending.cocci" that
renames the global variables like "active_nr", which are a shorthand
to referencing (in that case) a struct member as "the_index.cache_nr".
In doing so move more of "index-compatibility.pending.cocci" to
"index-compatibility.cocci".
In the case of "active_nr" we'd have a textual conflict with
"ab/various-leak-fixes" in "next"[1]. Let's exclude that specific case
while moving the rule over from "pending".

Replace the remaining calls of run_command_v_opt() with run_command()
calls and explict struct child_process variables. This is more verbose,
but not by much overall. The code becomes more flexible, e.g. it's easy
to extend to conditionally add a new argument.
Then remove the now unused function and its own flag names, simplifying
the run-command API.

Since we will likely be introducing a new hash function at some point,
and that hash function might be longer than 40 hex characters, use the
constant GIT_MAX_HEXSZ, which is designed to be suitable for
allocations, instead of GIT_SHA1_HEXSZ. This will ease the transition
down the line by distinguishing between places where we need to allocate
memory suitable for the largest hash from those where we need to handle
the current hash.

Before sha1_to_hex_r() existed, a simple way to get hex
sha1 into a buffer was with:
strcpy(buf, sha1_to_hex(sha1));
This isn't wrong (assuming the buf is 41 characters), but it
makes auditing the code base for bad strcpy() calls harder,
as these become false positives.
Let's convert them to sha1_to_hex_r(), and likewise for
some calls to find_unique_abbrev(). While we're here, we'll
double-check that all of the buffers are correctly sized,
and use the more obvious GIT_SHA1_HEXSZ constant.

We sometimes sprintf into fixed-size buffers when we know
that the buffer is large enough to fit the input (either
because it's a constant, or because it's numeric input that
is bounded in size). Likewise with strcpy of constant
strings.
However, these sites make it hard to audit sprintf and
strcpy calls for buffer overflows, as a reader has to
cross-reference the size of the array with the input. Let's
use xsnprintf instead, which communicates to a reader that
we don't expect this to overflow (and catches the mistake in
case we do).

I attempted to make index_state->cache[] a "const struct cache_entry **"
to find out how existing entries in index are modified and where. The
question I have is what do we do if we really need to keep track of on-disk
changes in the index. The result is
- diff-lib.c: setting CE_UPTODATE
- name-hash.c: setting CE_HASHED
- preload-index.c, read-cache.c, unpack-trees.c and
builtin/update-index: obvious
- entry.c: write_entry() may refresh the checked out entry via
fill_stat_cache_info(). This causes "non-const struct cache_entry
*" in builtin/apply.c, builtin/checkout-index.c and
builtin/checkout.c
- builtin/ls-files.c: --with-tree changes stagemask and may set
CE_UPDATE
Of these, write_entry() and its call sites are probably most
interesting because it modifies on-disk info. But this is stat info
and can be retrieved via refresh, at least for porcelain
commands. Other just uses ce_flags for local purposes.
So, keeping track of "dirty" entries is just a matter of setting a
flag in index modification functions exposed by read-cache.c. Except
unpack-trees, the rest of the code base does not do anything funny
behind read-cache's back.
The actual patch is less valueable than the summary above. But if
anyone wants to re-identify the above sites. Applying this patch, then
this:

There are two different static functions and one global function,
all of them called "merge_file()", with different signatures and
purposes. Rename them all to reduce confusion in "git grep" output:
* Rename the static one in merge-index to "merge_one_path(const char
*path)" as that function is about asking an external command to
resolve conflicts in one path.
* Rename the global one in merge-file.c that is only used by
merge-tree to "merge_blobs()", as the function takes three blobs and
returns the merged result only in-core, without doing anything to
the filesystem.
* Rename the one in merge-recursive to "merge_one_file()", just to be
fair.
Also rename merge-file.[ch] to merge-blobs.[ch].

This shrinks the top-level directory a bit, and makes it much more
pleasant to use auto-completion on the thing. Instead of
[torvalds@nehalem git]$ em buil<tab>
Display all 180 possibilities? (y or n)
[torvalds@nehalem git]$ em builtin-sh
builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c
builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o
[torvalds@nehalem git]$ em builtin-shor<tab>
builtin-shortlog.c builtin-shortlog.o
[torvalds@nehalem git]$ em builtin-shortlog.c
you get
[torvalds@nehalem git]$ em buil<tab> [type]
builtin/ builtin.h
[torvalds@nehalem git]$ em builtin [auto-completes to]
[torvalds@nehalem git]$ em builtin/sh<tab> [type]
shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o
[torvalds@nehalem git]$ em builtin/sho [auto-completes to]
[torvalds@nehalem git]$ em builtin/shor<tab> [type]
shortlog.c shortlog.o
[torvalds@nehalem git]$ em builtin/shortlog.c
which doesn't seem all that different, but not having that annoying
break in "Display all 180 possibilities?" is quite a relief.
NOTE! If you do this in a clean tree (no object files etc), or using an
editor that has auto-completion rules that ignores '*.o' files, you
won't see that annoying 'Display all 180 possibilities?' message - it
will just show the choices instead. I think bash has some cut-off
around 100 choices or something.
So the reason I see this is that I'm using an odd editory, and thus
don't have the rules to cut down on auto-completion. But you can
simulate that by using 'ls' instead, or something similar.
