When we detect that a `merge` can be skipped because the merged commit
is already an ancestor of HEAD, we do not need to commit, therefore
writing the MERGE_HEAD file is useless.
It is actually worse than useless: a subsequent `git commit` will pick
it up and think that we want to merge that commit, still.
To avoid that, move the code that writes the MERGE_HEAD file to a
location where we already know that the `merge` cannot be skipped.

When calling `merge` on a branch that has already been merged, that
`merge` is skipped quietly, but currently a MERGE_HEAD file is being
left behind and will then be grabbed by the next `pick` (that did
not want to create a *merge* commit).

When setting

"gcc (Raspbian 6.3.0-18+rpi1+deb9u1) 6.3.0 20170516" errors out with
"comparison is always false due to limited range of data type"
"[-Werror=type-limits]"
It turns out that the function xcurl_off_t() has 2 flavours:
- It gives a warning 32 bit systems, like Linux
- It takes the signed ssize_t as a paramter, but the only caller is using
a size_t (which is typically unsigned these days)
The original motivation of this function is to make sure that sizes > 2GiB
are handled correctly. The curl documentation says:
"For any given platform/compiler curl_off_t must be typedef'ed to a 64-bit
wide signed integral data type"
On a 32 bit system "size_t" can be promoted into a 64 bit signed value
without loss of data, and therefore we may see the
"comparison is always false" warning.
On a 64 bit system it may happen, at least in theory, that size_t is > 2^63,
and then the promotion from an unsigned "size_t" into a signed "curl_off_t"
may be a problem.
One solution to suppress a possible compiler warning could be to remove
the function xcurl_off_t().
However, to be on the very safe side, we keep it and improve it:
- The len parameter is changed from ssize_t to size_t
- A temporally variable "size" is used, promoted int uintmax_t and the compared
with "maximum_signed_value_of_type(curl_off_t)".
Thanks to Junio C Hamano for this hint.

When printing variables which contain a size, today "unsigned long"
is used at many places.
In order to be able to change the type from "unsigned long" into size_t
some day in the future, we need to have a way to print 64 bit variables
on a system that has "unsigned long" defined to be 32 bit, like Win64.
Upcast all those variables into uintmax_t before they are printed.
This is to prepare for a bigger change, when "unsigned long"
will be converted into size_t for variables which may be > 4Gib.

Change the GETTEXT_POISON compile-time + runtime GIT_GETTEXT_POISON
test parameter to only be a GIT_TEST_GETTEXT_POISON=<non-empty?>
runtime parameter, to be consistent with other parameters documented
in "Running tests with special setups" in t/README.
When I added GETTEXT_POISON in bb946bba76 ("i18n: add GETTEXT_POISON
to simulate unfriendly translator", 2011-02-22) I was concerned with
ensuring that the _() function would get constant folded if NO_GETTEXT
was defined, and likewise that GETTEXT_POISON would be compiled out
unless it was defined.
But as the benchmark in my [1] shows doing a one-off runtime
getenv("GIT_TEST_[...]") is trivial, and since GETTEXT_POISON was
originally added the GIT_TEST_* env variables have become the common
idiom for turning on special test setups.
So change GETTEXT_POISON to work the same way. Now the
GETTEXT_POISON=YesPlease compile-time option is gone, and running the
tests with GIT_TEST_GETTEXT_POISON=[YesPlease|] can be toggled on/off
without recompiling.
This allows for conditionally amending tests to test with/without
poison, similar to what 859fdc0c3c ("commit-graph: define
GIT_TEST_COMMIT_GRAPH", 2018-08-29) did for GIT_TEST_COMMIT_GRAPH. Do
some of that, now we e.g. always run the t0205-gettext-poison.sh test.
I did enough there to remove the GETTEXT_POISON prerequisite, but its
inverse C_LOCALE_OUTPUT is still around, and surely some tests using
it can be converted to e.g. always set GIT_TEST_GETTEXT_POISON=.
Notes on the implementation:
* We still compile a dedicated GETTEXT_POISON build in Travis
CI. Perhaps this should be revisited and integrated into the
"linux-gcc" build, see ae59a4e44f ("travis: run tests with
GIT_TEST_SPLIT_INDEX", 2018-01-07) for prior art in that area. Then
again maybe not, see [2].
* We now skip a test in t0000-basic.sh under
GIT_TEST_GETTEXT_POISON=YesPlease that wasn't skipped before. This
test relies on C locale output, but due to an edge case in how the
previous implementation of GETTEXT_POISON worked (reading it from
GIT-BUILD-OPTIONS) wasn't enabling poison correctly. Now it does,
and needs to be skipped.
* The getenv() function is not reentrant, so out of paranoia about
code of the form:
printf(_("%s"), getenv("some-env"));
call use_gettext_poison() in our early setup in git_setup_gettext()
so we populate the "poison_requested" variable in a codepath that's
won't suffer from that race condition.
* We error out in the Makefile if you're still saying
GETTEXT_POISON=YesPlease to prompt users to change their
invocation.
* We should not print out poisoned messages during the test
initialization itself to keep it more readable, so the test library
hides the variable if set in $GIT_TEST_GETTEXT_POISON_ORIG during
setup. See [3].
See also [4] for more on the motivation behind this patch, and the
history of the GETTEXT_POISON facility.

When git.rc is compiled into git.res, the result is actually dependent
on the architecture. That is, you cannot simply link a 32-bit git.res
into a 64-bit git.exe.
Therefore, to allow 32-bit and 64-bit builds in the same directory, we
let git.res depend on GIT-PREFIX so that it gets recompiled when
compiling for a different architecture (this works because the exec path
changes based on the architecture: /mingw32/libexec/git-core for 32-bit
and /mingw64/libexec/git-core for 64-bit).

When we see a time like "noon", we pass "12" to our date_time() helper,
which sets the hour to 12pm. If the current time is before noon, then we
wrap around to yesterday using date_yesterday(). But unlike the normal
calls to date_yesterday() from approxidate_alpha(), we pass a NULL "num"
parameter. Since c27cc94fad (approxidate: handle pending number for
"specials", 2018-11-02), that causes a segfault.
One way to fix this is by checking for NULL. But arguably date_time() is
abusing our helper by passing NULL in the first place (and this is the
only case where one of these "special" parsers is used this way). So
instead, let's have it just do the 1-day subtraction itself. It's still
just a one-liner due to our update_tm() helper.
Note that the test added here is a little funny, as we say "10am noon",
which makes the "10am" seem pointless. But this bug can only be
triggered when it the currently-parsed hour is before the special time.
The latest special time is "tea" at 1700, but t0006 uses a hard-coded
TEST_DATE_NOW of 1900. We could reset TEST_DATE_NOW, but that may lead
to confusion in other tests. Just saying "10am noon" makes this test
self-contained.

A git push process runs several processes during its run, but one
includes git send-pack which calls git pack-objects and passes
the known have/wants into stdin using object ids. However, the
default setting for core.warnAmbiguousRefs requires git pack-objects
to check for ref names matching the ref_rev_parse_rules array in
refs.c. This means that every object is triggering at least six
"file exists?" queries. When there are a lot of refs, this can
add up significantly! I observed a simple push spending three
seconds checking these paths.
The fix here is similar to 4c30d50 "rev-list: disable object/refname
ambiguity check with --stdin". While the get_object_list() method
reads the objects from stdin, turn warn_on_object_refname_ambiguity
flag (which is usually true) to false. Just for code hygiene, save
away the original at the beginning and restore it once we are done.

We usually just forward the --verify-signatures option along to
git-merge, and trust it to do the right thing. However, when we are on
an unborn branch (i.e., there is no HEAD yet), we handle this case
ourselves without even calling git-merge. And in this code path, we do
not respect the verification option at all.
It may be more maintainable in the long run to call git-merge for the
unborn case. That would fix this bug, as well as prevent similar ones in
the future. But unfortunately it's not easy to do. As t5520.3
demonstrates, there are some special cases that git-merge does not
handle, like "git pull .. master:master" (by the time git-merge is
invoked, we've overwritten the unborn HEAD).

When git-merge sees that we are on an unborn branch (i.e., there is no
HEAD), it follows a totally separate code path than the usual merge
logic. This code path does not know about verify_signatures, and so we
fail to notice bad or missing signatures.
This has been broken since --verify-signatures was added in efed002249
(merge/pull: verify GPG signatures of commits being merged, 2013-03-31).
In an ideal world, we'd unify the flow for this case with the regular
merge logic, which would fix this bug and avoid introducing similar
ones. But because the unborn case is so different, it would be a burden
on the rest of the function to continually handle the missing HEAD. So
let's just port the verification check to this special case.

This is correct, but we can be a bit more defensive. If there were ever

When we define a parse-options callback, the flags we put in the option
struct must match what the callback expects. For example, a callback
which does not handle the "unset" parameter should only be used with
PARSE_OPT_NONEG. But since the callback and the option struct are not
defined next to each other, it's easy to get this wrong (as earlier
patches in this series show).
Fortunately, the compiler can help us here: compiling with
-Wunused-parameters can show us which callbacks ignore their "unset"
parameters (and likewise, ones that ignore "arg" expect to be triggered
with PARSE_OPT_NOARG).
But after we've inspected a callback and determined that all of its
callers use the right flags, what do we do next? We'd like to silence
the compiler warning, but do so in a way that will catch any wrong calls
in the future.
We can do that by actually checking those variables and asserting that
they match our expectations. Because this is such a common pattern,
we'll introduce some helper macros. The resulting messages aren't
as descriptive as we could make them, but the file/line information from
BUG() is enough to identify the problem (and anyway, the point is that
these should never be seen).
Each of the annotated callbacks in this patch triggers
-Wunused-parameters, and was manually inspected to make sure all callers
use the correct options (so none of these BUGs should be triggerable).

Running "git pack-objects --no-index-version" will segfault, since the
callback is not prepared to handle the "unset" flag.
In theory this might be used to counteract an earlier "--index-version",
or override a pack.indexversion config setting. But the semantics aren't
immediately obvious, and it's unlikely anybody wants this. Let's just
disable the broken option for now.

Running "git ls-files --no-exclude" will currently segfault, as its
option callback does not handle the "unset" parameter.
In theory this could be used to clear the exclude list, but it is not
clear how that would interact with the other exclude options, nor is the
current code capable of clearing the list. Let's just disable the broken
option.
Note that --no-exclude-from will similarly segfault, but
--no-exclude-standard will not. It just silently does the wrong thing
(pretending as if --exclude-standard was specified).
