There has never been a show_date_human() function on the "master"
branch in git.git. This declaration was added in b841d4ff438 (Add
`human` format to test-tool, 2019-01-28).
A look at the ML history reveals that it was leftover cruft from an
earlier version of that commit[1].

When "git fetch --prune" failed to prune the refs it wanted to
prune, the command issued error messages but exited with exit
status 0, which has been corrected.

When pruning refs fails, we print an error to stderr, but still
exit 0 from 'git fetch'. Since this is a genuine error, fetch
should be exiting with some non-zero exit code. Make it so.
The --prune option was introduced in f360d844de ("builtin-fetch: add
--prune option", 2009-11-10). Unfortunately it's unclear from that
commit whether ignoring the exit code was an oversight or
intentional, but it feels like an oversight.

Remove the now-unused "failure_errno" parameter from the
refs_resolve_ref_unsafe() signature. In my recent 96f6623ada0 (Merge
branch 'ab/refs-errno-cleanup', 2021-11-29) series we made all of its
callers explicitly request the errno via an output parameter.
As that series shows all but one caller ended up passing in a
boilerplate "ignore_errno", since they only cared about whether the
return value was NULL or not, i.e. if the ref could be resolved.
There was one small issue with that series fixed with a follow-up in
31e39123695 (Merge branch 'ab/refs-errno-cleanup', 2022-01-14) a small
bug in that series was fixed.
After those two there was one caller left in sequencer.c that used the
"failure_errno', but as of the preceding commit it uses a boilerplate
"ignore_errno" instead.
This leaves the public refs API without any use of "failure_errno" at
all. We could still do with a bit of cleanup and generalization
between refs.c and refs/files-backend.c before the "reftable"
integration lands, but that's all internal to the reference code
itself.
So let's remove this output parameter. Not only isn't it used now, but
it's unlikely that we'll want it again in the future. We'd like to
slowly move the refs API to a more file-backend independent way of
communicating error codes, having it use a "failure_errno" was only
the first step in that direction. If this or any other function needs
to communicate what specifically is wrong with the requested "refname"
it'll be better to have the function set some output enum of
well-defined error states than piggy-backend on "errno".

Change code that was faithfully migrated to the new "resolve_errno"
API in ed90f04155d (refs API: make resolve_ref_unsafe() not set errno,
2021-10-16) to stop caring about the errno at all.
When we fail to resolve "HEAD" after the sequencer runs it doesn't
really help to say what the "errno" value is, since the fake backend
errno may or may not reflect anything real about the state of the
".git/HEAD". With the upcoming reftable backend this fakery will
become even more pronounced.
So let's just die() instead of die_errno() here. This will also help
simplify the refs_resolve_ref_unsafe() API. This was the only user of
it that wasn't ignoring the "failure_errno" output parameter.

The current way we generate random file names is by taking the seconds
and microseconds, plus the PID, and mixing them together, then encoding
them. If this fails, we increment the value by 7777, and try again up
to TMP_MAX times.
Unfortunately, this is not the best idea from a security perspective.
If we're writing into TMPDIR, an attacker can guess these values easily
and prevent us from creating any temporary files at all by creating them
all first. Even though we set TMP_MAX to 16384, this may be achievable
in some contexts, even if unlikely to occur in practice.
Fortunately, we can simply solve this by using the system
cryptographically secure pseudorandom number generator (CSPRNG) to
generate a random 64-bit value, and use that as before. Note that there
is still a small bias here, but because a six-character sequence chosen
out of 62 characters provides about 36 bits of entropy, the bias here is
less than 2^-28, which is acceptable, especially considering we'll retry
several times.
Note that the use of a CSPRNG in generating temporary file names is also
used in many libcs. glibc recently changed from an approach similar to
ours to using a CSPRNG, and FreeBSD and OpenBSD also use a CSPRNG in
this case. Even if the likelihood of an attack is low, we should still
be at least as responsible in creating temporary files as libc is.

There are many situations in which having access to a cryptographically
secure pseudorandom number generator (CSPRNG) is helpful. In the
future, we'll encounter one of these when dealing with temporary files.
To make this possible, let's add a function which reads from a system
CSPRNG and returns some bytes.
We know that all systems will have such an interface. A CSPRNG is
required for a secure TLS or SSH implementation and a Git implementation
which provided neither would be of little practical use. In addition,
POSIX is set to standardize getentropy(2) in the next version, so in the
(potentially distant) future we can rely on that.
For systems which lack one of the other interfaces, we provide the
ability to use OpenSSL's CSPRNG. OpenSSL is highly portable and
functions on practically every known OS, and we know it will have access
to some source of cryptographically secure randomness. We also provide
support for the arc4random in libbsd for folks who would prefer to use
that.
Because this is a security sensitive interface, we take some
precautions. We either succeed by filling the buffer completely as we
requested, or we fail. We don't return partial data because the caller
will almost never find that to be a useful behavior.
Specify a makefile knob which users can use to specify one or more
suitable CSPRNGs, and turn the multiple string options into a set of
defines, since we cannot match on strings in the preprocessor. We allow
multiple options to make the job of handling this in autoconf easier.
The order of options is important here. On systems with arc4random,
which is most of the BSDs, we use that, since, except on MirBSD and
macOS, it uses ChaCha20, which is extremely fast, and sits entirely in
userspace, avoiding a system call. We then prefer getrandom over
getentropy, because the former has been available longer on Linux, and
then OpenSSL. Finally, if none of those are available, we use
/dev/urandom, because most Unix-like operating systems provide that API.
We prefer options that don't involve device files when possible because
those work in some restricted environments where device files may not be
available.
Set the configuration variables appropriately for Linux and the BSDs,
including macOS, as well as Windows and NonStop. We specifically only
consider versions which receive publicly available security support
here. For the same reason, we don't specify getrandom(2) on Linux,
because CentOS 7 doesn't support it in glibc (although its kernel does)
and we don't want to resort to making syscalls.
Finally, add a test helper to allow this to be tested by hand and in
tests. We don't add any tests, since invoking the CSPRNG is not likely
to produce interesting, reproducible results.

Doc and test update around the eol attribute.

The documentation for the eol attribute states that it is "effectively
setting the text attribute". However, this implies that it forces the
text attribute to always be set, which has not been the case since
6523728499 ("convert: unify the "auto" handling of CRLF", 2016-06-28).
Let's avoid confusing users (and the present author when trying to
describe Git's behavior to others) by clearly documenting in which
cases the "eol" attribute has effect.
Specifically, the attribute always has an effect unless the file is
explicitly set as -text, or the file is set as text=auto and the file is
detected as binary.

Right now, it isn't clear what the behavior is when the eol attribute is
set in .gitattributes but the text attribute is not. Let's add some
tests to document this behavior in our code, which happens to be that
the behavior is as if we set the text attribute implicitly. This will
make sure we don't accidentally change the behavior, which somebody is
probably relying on, and serve as documentation to developers.

mem_pool_alloc uses sizeof(uintmax_t) as a proxy for what should be
_Alignof(max_align_t) in C11. On most architectures this is sufficient
(though on m68k it is in fact overly strict, since the de-facto ABI,
which differs from the specified System V ABI, has the maximum alignment
of all types as 2 bytes), but on CHERI, and thus Arm's Morello
prototype, it is insufficient for any type that stores a pointer, which
must be aligned to 128 bits (on 64-bit architectures extended with
CHERI), whilst uintmax_t is a 64-bit integer.
Fix this by introducing our own approximation for max_align_t and a
means to compute _Alignof it without relying on C11. Currently this
union only contains uintmax_t and void *, but more types can be added as
needed.

In 61feddcdf28 (tests: disable GIT_TEST_SPLIT_INDEX for sparse index
tests, 2021-08-26), it was already called out that the split index
feature is incompatible with the sparse index feature, and its commit
message wondered aloud whether more checks would be required to ensure
that the split index and sparse index features aren't enabled at the
same time.
We are about to introduce such additional checks, and indeed, t1091
would utterly fail with them. Therefore, let's preemptively disable the
split index for the entirety of t1091.
This partially reverts above-mentioned patch because it covered only one
test case whereas we want to cover the entire test script.

In 6e773527b6b (sparse-index: convert from full to sparse, 2021-03-30),
we introduced initial support for a sparse index, and were careful to
avoid converting to a sparse index in the presence of a split index.
However, when we _just_ read a freshly-initialized index, it might not
contain a split index even if _writing_ it will add one by virtue of
being asked for via the `GIT_TEST_SPLIT_INDEX` variable.
We did not notice any problems with checking _only_ for `split_index`
(and not `GIT_TEST_SPLIT_INDEX`) right until both
`vd/sparse-sparsity-fix-on-read` _and_ `vd/sparse-reset` were merged.
Those two topics' interplay triggers a bug in conjunction with running
t1091.15 when `GIT_TEST_SPLIT_INDEX=true` in the following way:
`vd/sparse-sparsity-fix-on-read` ensures that the index is made sparse
right after reading, and `vd/sparse-reset` ensures that the index is
made non-sparse again unless running in the `--soft` mode. Since the
split index feature is incompatible with the sparse index feature, we
see a symptom like this:
fatal: position for replacement 4 exceeds base index size 4
Let's fix this by avoiding the conversion to a sparse index when
`GIT_TEST_SPLIT_INDEX=true`.

Cloning from a repository that does not yet have any branches or

error", which has been corrected.

When cloning a branchless and tagless but not refless remote using
protocol v0 or v1, Git calls transport_fetch_refs() with an empty ref
list. This makes the clone fail with the message "remote transport
reported error".
Git should have refrained from calling transport_fetch_refs(), just like
it does in the case that the remote is refless. Therefore, teach Git to
do this.
In protocol v2, this does not happen because the client passes
ref-prefix arguments that filter out non-branches and non-tags in the
ref advertisement, making the remote appear empty.
Note that this bug concerns logic in builtin/clone.c and only affects
cloning, not fetching.

"git sparse-checkout init" failed to write into $GIT_DIR/info

been corrected to auto-create it.

sparse-checkout: create leading directory

When creating the sparse-checkout file, Git does not create the leading
directory, "$GIT_DIR/info", if it does not exist. This causes problems
if the repository does not have that directory. Therefore, ensure that
the leading directory is created.
This is the only "open" in builtin/sparse-checkout.c that does not have
a leading directory check. (The other one in write_patterns_and_update()
does.)
Note that the test needs to explicitly specify a template when running
"git init" because the default template used in the tests has the
"info/" directory included.

There were two commit_lists created in cmd_merge() that were only

The documentation for merge_incore_recursive(), modelled after
merge_recursive(), notes that
merge_bases will be consumed (emptied) so make a copy if you need it
However, in merge_ort_internal() (which merge_incore_recursive() calls),
it runs
merged_merge_bases = pop_commit(&merge_bases);
...
for (iter = merge_bases; iter; iter = iter->next) {
...
}
In other words, it only consumes the *first* entry of merge_bases, and
the rest it iterates through. If it iterated through all of them, the
caller could be responsible for free'ing the memory. If it consumed all
of them, the current documentation would be correct and the callers
would need to do nothing. The current middle ground makes it impossible
for callers to avoid memory leaks, since any attempt to use the
merge_bases it passes in would result in a use-after-free.
It turns out this part of the code was copied from merge-recursive.c,
which has had the same bug for 15.5 years. However, since we are trying
to keep merge-recursive.c stable as we sunset it, let's just fix the
leak in in merge_ort_internal() by having it actually consume all the
elements of the merge_bases commit_list.
Testing this commit against t6404 (the first testcase specifically
about recursive merges) under valgrind shows that this patch fixes
the following leak:

This removes the last direct user of "run_hook_ve()" outside of

Instead of duplicating the behavior of run-command.h:run_hook_le() in
Python, we can directly call 'git hook run'. We emulate the existence
check with the --ignore-missing flag.
We're dropping the "verbose" handling added in 9f59ca4d6af (git-p4:
create new function run_git_hook, 2020-02-11), those who want
diagnostic output about how hooks are run are now able to get that via
e.g. the trace2 facility and GIT_TRACE=1.

Change the "sendmail-validate" hook to be run via the "git hook run"
wrapper instead of via a direct invocation.
This is the smallest possibly change to get "send-email" using "git
hook run". We still check the hook itself with "-x", and set a
"GIT_DIR" variable, both of which are asserted by our tests. We'll
need to get rid of this special behavior if we start running N hooks,
but for now let's be as close to bug-for-bug compatible as possible.

For certain one-shot hooks we'd like to optimistically run them, and
not complain if they don't exist.
This was already supported by the underlying hook.c library, but had
not been exposed via "git hook run". The command version of this will
be used by send-email in a subsequent commit.
