As we'll address in subsequent commits the "DC_SHA1=YesPlease" is not
on by default on OSX, instead we use Apple Common Crypto's SHA-1
implementation.
In 6beb2688d33 (fsmonitor: relocate socket file if .git directory is
remote, 2022-10-04) the build was broken with "DC_SHA1=YesPlease" (and
probably other non-"APPLE_COMMON_CRYPTO" SHA-1 backends).
So let's extract the fix for this from [1] to get the build working
again with "DC_SHA1=YesPlease". In addition to the fix in [1] we also
need to replace "SHA_DIGEST_LENGTH" with "GIT_MAX_RAWSZ".

The compiler may eliminate "str" as a stack variable, and just leave it
in a register. The register is preserved through most of the function,
including across the call to some_func(), since we'd eventually need to
free it. But because die() is marked with NORETURN, the compiler knows
that it doesn't need to save registers, and just clobbers it.
When die() eventually exits, the leak-checker runs. It looks in
registers and on the stack for any reference to the memory allocated by
str (which would indicate that it's not leaked), but can't find one. So
it reports it as a leak.
Neither system is wrong, really. The C standard (mostly section 5.1.2.3)
defines an abstract machine, and compilers are allowed to modify the
program as long as the observable behavior of that abstract machine is
unchanged. Looking at random memory values on the stack is undefined
behavior, and not something that the optimizer needs to support. But
there really isn't any other way for a leak checker to work; it
inherently has to do undefined things like scouring memory for pointers.
So the two things are inherently at odds with each other. We can't fix
it by changing the code, because from the perspective of the program
running in an abstract machine, there is no leak.
This has caused real false positives in the past, like:
This patch makes those go away by forcing -O0 when compiling with LSan.
There are a few ways we could do this:
- we could just teach the linux-leaks CI job to set -O0. That's the
smallest change, and means we wouldn't get spurious CI failures. But
it doesn't help people looking for leaks manually or in a specific
test (and because the problem depends on the vagaries of the
optimizer, investigating these can waste a lot of time in
head-scratching as the problem comes and goes)
- we default to -O2 in CFLAGS; we could pull this out to a separate
variable ("-O$(O)" or something) and modify "O" when LSan is in use.
This is the most flexible, in that you could still build with "make
O=2 SANITIZE=leak" if you really wanted to (say, for experimenting).
But it would also fail to kick in if the user defines their own
CFLAGS variable, which again leads to head-scratching.
- we can just stick -O0 into BASIC_CFLAGS when enabling LSan. Since
this comes after the user-provided CFLAGS, it will override any
previous -O setting found there. This is more foolproof, albeit less
flexible. If you want to experiment with an optimized leak-checking
build, you'll have to put "-O2 -fsanitize=leak" into CFLAGS
manually, rather than using our SANITIZE=leak Makefile magic.
Since the final one is the least likely to break in normal use, this
patch uses that approach.
The resulting build is a little slower, of course, but since LSan is
already about 2x slower than a regular build, another 10% slowdown isn't
that big a deal.

grep.c: remove "extended" in favor of "pattern_expression", fix segfault
Since 79d3696cfb4 (git-grep: boolean expression on pattern matching.,
2006-06-30) the "pattern_expression" member has been used for complex
queries (AND/OR...), with "pattern_list" being used for the simple OR
queries. Since then we've used both "pattern_expression" and its
associated boolean "extended" member to see if we have a complex
expression.
Since f41fb662f57 (revisions API: have release_revisions() release
"grep_filter", 2022-04-13) we've had a subtle bug relating to that: If
we supplied options that were only used for "complex queries", but
didn't supply the query itself we'd set "opt->extended", but would
have a NULL "pattern_expression". As a result these would segfault as
we tried to call "free_grep_patterns()" from "release_revisions()":
The root cause of this is that we were conflating the state management
we needed in "compile_grep_patterns()" itself with whether or not we
had an "opt->pattern_expression" later on.
In this cases as we're going through "compile_grep_patterns()" we have
no "opt->pattern_list" but have "opt->no_body_match" or
"opt->all_match". So we'd set "opt->extended = 1", but not "return" on
"opt->extended" as that's an "else if" in the same "if" statement.
That behavior is intentional and required, as the common case is that
we have an "opt->pattern_list" that we're about to parse into the
"opt->pattern_expression".
But we don't need to keep track of this "extended" flag beyond the
state management in compile_grep_patterns() itself. It needs it, but
once we're out of that function we can rely on
"opt->pattern_expression" being non-NULL instead for using these
extended patterns.
As 79d3696cfb4 itself shows we've assumed that there's a one-to-one
mapping between the two since the very beginning. I.e. "match_line()"
would check "opt->extended" to see if it should call "match_expr()",
and the first thing we do in that function is assume that we have a
"opt->pattern_expression". We'd then call "match_expr_eval()", which
would have died if that "opt->pattern_expression" was NULL.
The "die" was added in c922b01f54c (grep: fix segfault when "git grep
'('" is given, 2009-04-27), and can now be removed as it's now clearly
unreachable. We still do the right thing in the case that prompted
that fix:
git grep '('
fatal: unmatched parenthesis
Arguably neither the "--invert-grep" option added in [1] nor the
earlier "--all-match" option added in [2] were intended to be used
stand-alone, and another approach[3] would be to error out in those
cases. But since we've been treating them as a NOOP when given without
--grep for a long time let's keep doing that.
We could also return in "free_pattern_expr()" if the argument is
non-NULL, as an alternative fix for this segfault does [4]. That would
be more elegant in making the "free_*()" function behave like
"free()", but it would also remove a sanity check: The
"free_pattern_expr()" function calls itself recursively, and only the
top-level is allowed to be NULL, let's not conflate those two
conditions.

CodingGuidelines: mention C99 features we can't use
The C99 section of the CodingGuidelines is a good overview of what we
can use, but is sorely lacking in what we can't use. Something that
comes up occasionally is the portability of %z.
Per [1] we couldn't use it for the longest time due to MSVC not
supporting it, but nowadays by requiring C99 we rely on the MSVC
version that does, but we can't use it yet because a C library that
MinGW uses doesn't support it.
CodingGuidelines: allow declaring variables in for loops
Since 44ba10d6712 (revision: use C99 declaration of variable in for()
loop, 2021-11-14) released with v2.35.0 we've had a variable declared
with in a for loop.
Since then we've had inadvertent follow-ups to that with at least cb2607759e2 (merge-ort: store more specific conflict information,
2022-06-18) released with v2.38.0.
As November 2022 is within the window of this upcoming release,
let's update the guideline to allow this. We can have the promised
"revisit" discussion while this patch cooks, and drop it if it turns
out that it is still premature, which is not expected to happen at

CodingGuidelines: mention dynamic C99 initializer elements
The first use of variables in initializer elements appears to have
been 2b6854c863a (Cleanup variables in cat-file, 2007-04-21) released
with v1.5.2.
Some of those caused portability issues, and e.g. that "cat-file" use
was changed in 66dbfd55e38 (Rewrite dynamic structure initializations
to runtime assignment, 2010-05-14) which went out with v1.7.2.
But curiously 66dbfd55e38 missed some of them, e.g. an archive.c use
added in d5f53d6d6f2 (archive: complain about path specs that don't
match anything, 2009-12-12), and another one in merge-index.c (later
builtin/merge-index.c) in 0077138cd9d (Simplify some instances of
run_command() by using run_command_v_opt()., 2009-06-08).
As far as I can tell there's been no point since 2b6854c863a in 2007
where a compiler that didn't support this has been able to compile
git. Presumably 66dbfd55e38 was an attempt to make headway with wider
portability that ultimately wasn't completed.
In any case, we are thoroughly reliant on this syntax at this point,

config.mak.dev: disable suggest braces error on old clang versions
Add the "-Wno-missing-braces" option when building with an old version

2 errors generated.
This example compiles without error/warning with updated versions of
clang. Since this is an obsolete error, use the -Wno-missing-braces
option to silence the warning when using an older compiler. This
avoids the need to update the code to use "{{0}}" style
initializations.

symbolic-ref: teach "--[no-]recurse" option
Suppose you are managing many maintenance tracks in your project,

Further imagine that your project recently tagged the official 2.38
release, which means you would need to start maint-2.38 track soon,

So far, so good. But it also is reasonable to want not to have to
worry about which maintenance track is the latest, by pointing a
more generic-sounding 'maint' branch at it, by doing:
It is arguably better to say that we are on 'maint-2.38' rather than
on 'maint', and "git merge/pull" would record "into maint-2.38" and
not "into maint", so I think what we have is a good behaviour.
One thing that is slightly irritating, however, is that I do not
think there is a good way (other than "cat .git/HEAD") to learn that
you checked out 'maint' to get into that state. Just like the output
of "git branch --show-current" shows above, "git symbolic-ref HEAD"
would report 'refs/heads/maint-2.38', bypassing the intermediate
symbolic ref at 'refs/heads/maint' that is pointed at by HEAD.
The internal resolve_ref() API already has the necessary support for
stopping after resolving a single level of a symbolic-ref, and we
can expose it by adding a "--[no-]recurse" option to the command.

git-compat-util.h: GCC deprecated message arg only in GCC 4.5+
https://gcc.gnu.org/gcc-4.5/changes.html says
The deprecated attribute now takes an optional string argument, for
example, __attribute__((deprecated("text string"))), that will be
printed together with the deprecation warning.
While GCC 4.5 is already 12 years old, git checks for even older
versions in places. Let's not needlessly break older compilers when
a small and simple fix is readily available.

"git" built with RUNTIME_PREFIX flag turned on could figure out
gitexecdir and other paths as relative to "git" executable.
However, in the section specifies gitexecdir, RUNTIME_PREFIX wasn't
mentioned, thus users may wrongly assume that "git" always locates
gitexecdir as relative path to the executable.
Let's clarify that only "git" built with RUNTIME_PREFIX will locate
gitexecdir as relative path.

gc: simplify maintenance_task_pack_refs()
Pass a constant string array directly to run_command_v_opt() instead of
copying it into a strvec first. This shortens the code and avoids heap
allocations.
