Commit 8db2dad7a0 (parse_object(): check on-disk type of suspected blob,
2022-11-17) simplified the conditional for checking if we might have a
blob. But we can simplify it further. In:
!obj || (obj && obj->type == OBJ_BLOB)
the short-circuit "OR" means "obj" will always be true on the right-hand
side. The compiler almost certainly optimized that out anyway, but
dropping it makes the conditional easier to understand for humans.

This is because "git-push" will run in a tty in this case, and the

For a lot of uses of UNLEAK() it would be quite tricky to release the
memory involved, or we're missing the relevant *_(release|clear)()
functions. But in these cases we have them already, and can just
invoke them on the variable(s) involved, instead of UNLEAK().
For "builtin/worktree.c" the UNLEAK() was also added in [1], but the
struct member it's unleaking was removed in [2]. The only non-"int"
member of that structure is "const char *keep_locked", which comes to
us via "argv" or a string literal[3].
We have good visibility via the compiler and
tooling (e.g. SANITIZE=address) on bad free()-ing, but none on
UNLEAK() we don't need anymore. So let's prefer releasing the memory
when it's easy.
For "bugreport", "worktree" and "config" we need to start using a "ret
= ..." return pattern. For "builtin/bugreport.c" these UNLEAK() were
added in [4], and for "builtin/config.c" in [1].
For "config" the code seen here was the only user of the "value"
variable. For "ACTION_{RENAME,REMOVE}_SECTION" we need to be sure to
return the right exit code in the cases where we were relying on
falling through to the top-level.
I think there's still a use-case for UNLEAK(), but hat it's changed
since then. Using it so that "we can see the real leaks" is
counter-productive in these cases.
It's more useful to have UNLEAK() be a marker of the remaining odd
cases where it's hard to free() the memory for whatever reason. With
this change less than 20 of them remain in-tree.

At this point we could get several more tests leak-free by free()-ing

supposedly owns it, but sometimes we don't call it. I have a fix for

Fix a leak in the recent 6159e7add4 (rebase --abort: improve reflog
message, 2022-10-12). Before that commit we'd strbuf_release() the
reflog message we were formatting, but when that code was refactored
to use "ropts.head_msg" the strbuf_release() was omitted.
Ideally the three users of "ropts" in cmd_rebase() should use
different "ropts" variables, in practice they're completely separate,
as this and the other user in the "switch" statement will "goto
cleanup", which won't touch "ropts".
The third caller after the "switch" is then unreachable if we take
these two branches, so all of them are getting a "{ 0 }" init'd
"ropts".
So it's OK that we're leaving a stale pointer in "ropts.head_msg",
cleaning it up was our responsibility, and it won't be used again.

When "read_strategy_opts()" is called we may have populated the
"opts->strategy" before, so we'll need to free() it to avoid leaking
memory.
We populate it before because we cal get_replay_opts() from within
"rebase.c" with an already populated "opts", which we then copy. Then
if we're doing a "rebase -i" the sequencer API itself will promptly
clobber our alloc'd version of it with its own.
If this code is changed to do, instead of the added free() here a:
if (opts->strategy)
opts->strategy = xstrdup("another leak");
We get a couple of stacktraces from -fsanitize=leak showing how we
ended up clobbering the already allocated value, i.e.:

This can be seen in e.g. the 4th test of
"t3404-rebase-interactive.sh".
In the larger picture the ownership of the "struct replay_opts" is
quite a mess, e.g. in this case rebase.c's static "get_replay_opts()"
function partially creates it, but nothing in rebase.c will free()
it. The structure is "mostly owned" by the sequencer API, but it also
expects to get these partially populated versions of it.
It would be better to have rebase keep track of what it allocated, and
free() that, and to pass that as a "const" to the sequencer API, which
would copy what it needs to its own version, and to free() that.
But doing so is a much larger change, and however messy the ownership
boundary is here is consistent with what we're doing already, so let's
just free() this to fix the leak.

The read_cache() in prepare_to_commit() would end up clobbering the
pointer we had for a previously populated "the_index.cache_tree" in
the very common case of "git commit" stressed by e.g. the tests being
changed here.
We'd populate "the_index.cache_tree" by calling
"update_main_cache_tree" in prepare_index(), but would not end up with
a "fully prepared" index. What constitutes an existing index is
clearly overly fuzzy, here we'll check "active_nr" (aka
"the_index.cache_nr"), but our "the_index.cache_tree" might have been
malloc()'d already.
Thus the code added in 11c8a74a64 (commit: write cache-tree data when
writing index anyway, 2011-12-06) would end up allocating the
"cache_tree", and would interact here with code added in
7168624c35 (Do not generate full commit log message if it is not
going to be used, 2007-11-28). The result was a very common memory

* For those whose call was followed by perror("<macro-name>"), change
it to perror("<function-name>"), referring to the new function.

In a preceding commit we fully applied the
"index-compatibility.pending.cocci" rule to "t/helper/*".
Let's now stop defining "USE_THE_INDEX_COMPATIBILITY_MACROS" in
test-tool.h itself, and instead instead define
"USE_THE_INDEX_VARIABLE" in the individual test helpers that need
it. This mirrors how we do the same thing in the "builtin/" directory.

Split up the "USE_THE_INDEX_COMPATIBILITY_MACROS" into that setting
and a more narrow "USE_THE_INDEX_VARIABLE". In the case of these
built-ins we only need "the_index" variable, but not the compatibility
wrapper for functions we're not using.
Let's then have some users of "USE_THE_INDEX_COMPATIBILITY_MACROS" use
this more narrow and descriptive define.
For context: The USE_THE_INDEX_COMPATIBILITY_MACROS macro was added to
test-tool.h in f8adbec9fe (cache.h: flip
NO_THE_INDEX_COMPATIBILITY_MACROS switch, 2019-01-24).

Apply the "index-compatibility.pending.cocci" rule to the "t/helper/*"
directory, a subsequent commit will extend cache.h to further narrow
down the use of "USE_THE_INDEX_COMPATIBILITY_MACROS" in this area.

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".

Apply a selection of rules in "index-compatibility.pending.cocci"
tree-wide, and in doing so migrate them to
"index-compatibility.cocci".
As in preceding commits the only manual changes here are the macro
removals in "cache.h", and the update to the '*.cocci" rules. The rest
of the C code changes are the result of applying those updated rules.
Move rules for some rarely used cache compatibility macros from
"index-compatibility.pending.cocci" to "index-compatibility.cocci" and
apply them.

Add a coccinelle rule which covers the rest of the macros guarded by
"USE_THE_INDEX_COMPATIBILITY_MACROS" cache.h. If the result of this
were applied it can be reduced down to just:
#ifdef USE_THE_INDEX_COMPATIBILITY_MACROS
extern struct index_state the_index;
#endif
But that patch is just under 2000 lines, so let's first add this as a
"pending", and then incrementally pick changes from it in subsequent
commits. In doing that we'll migrate rules from this
"index-compatibility.pending.cocci" to the "index-compatibility.cocci"
created in a preceding commit.

The discard_index() function has not returned non-zero since
7a51ed66f6 (Make on-disk index representation separate from in-core
one, 2008-01-14), but we've had various code in-tree still acting as
though that might be the case.

Since 4aab5b46f4 (Make read-cache.c "the_index" free., 2007-04-01)
we've been undergoing a slow migration away from these macros, but
haven't made much progress since f8adbec9fe (cache.h: flip
NO_THE_INDEX_COMPATIBILITY_MACROS switch, 2019-01-24).
Let's move forward a bit by changing the users of those macros that
are rare enough that we can convert them in one go, and then remove
the compatibility shim.
The only manual change to the C code here is to "cache.h", the rest is
all the result of applying the new "index-compatibility.cocci".
Even though it's a one-off, let's keep the coccinelle rules for
now. We'll extend them in subsequent commits, and this will help
anything that's in-flight or out-of-tree to migrate.

Adding "USE_THE_INDEX_COMPATIBILITY_MACROS" to these two appears to
have been unnecessary from the start, as going back and compiling
f8adbec9fe (cache.h: flip NO_THE_INDEX_COMPATIBILITY_MACROS switch,
2019-01-24) without that addition works.
Let's not have these ask for the compatibility macros from cache.h
that they don't need.

The "active_alloc" macro added in 228e94f935 (Move index-related
variables into a structure., 2007-04-01) has not been used since
4aab5b46f4 (Make read-cache.c "the_index" free., 2007-04-01). Let's
remove it.
The rest of these are likewise unused, so let's not keep them
around. E.g. 12cd0bf9b0 (dir: stop using the index compatibility
macros, 2017-05-05) is the last use of "cache_dir_exists".
