Under normal circumstances, it shouldn't ever happen that a repository
has no HEAD reference. In fact, git-update-ref(1) would fail any request
to delete the HEAD reference, and a newly initialized repository always
pre-creates it, too.
We have however changed git-clone(1) to partially initialize the
refdb just up to the point where remote helpers can find the
repository. With that change, we are going to run into a situation
where repositories have no refs at all.
Now there is a very particular edge case in this situation: when
preparing an empty ref transacton, we end up returning whatever value
`read_ref_without_reload()` returned to the caller. Under normal
conditions this would be fine: "HEAD" should usually exist, and thus the
function would return `0`. But if "HEAD" doesn't exist, the function
returns a positive value which we end up returning to the caller.
Fix this bug by resetting the return code to `0` and add a test.

In 18c9cb7524 (builtin/clone: create the refdb with the correct object
format, 2023-12-12), we have changed git-clone(1) so that it delays
creation of the refdb until after it has learned about the remote's
object format. This change was required for the reftable backend, which
encodes the object format into the tables. So if we pre-initialized the
refdb with the default object format, but the remote uses a different
object format than that, then the resulting tables would have encoded
the wrong object format.
This change unfortunately breaks remote helpers which try to access the
repository that is about to be created. Because the refdb has not yet
been initialized at the point where we spawn the remote helper, we also
don't yet have "HEAD" or "refs/". Consequently, any Git commands ran by
the remote helper which try to access the repository would fail because
it cannot be discovered.
This is essentially a chicken-and-egg problem: we cannot initialize the
refdb because we don't know about the object format. But we cannot learn
about the object format because the remote helper may be unable to
access the partially-initialized repository.
Ideally, we would address this issue via capabilities. But the remote
helper protocol is not structured in a way that guarantees that the
capability announcement happens before the remote helper tries to access
the repository.
Instead, fix this issue by partially initializing the refdb up to the
point where it becomes discoverable by Git commands.

The reason why we require the <git-compat-util.h> file to be the
first header file to be included is because it insulates other
header files and source files from platform differences, like which
system header files must be included in what order, and what C
preprocessor feature macros must be defined to trigger certain
features we want out of the system.
We tried to clarify the rule in the coding guidelines document, but
the wording was a bit fuzzy that can lead to misinterpretations like
you can include <xdiff/xinclude.h> only to avoid having to include
<git-compat-util.h> even if you have nothing to do with the xdiff
implementation, for example. "You do not have to include more than
one of these" was also misleading and would have been puzzling if
you _needed_ to depend on more than one of these approved headers
(answer: you are allowed to include them all if you need the
declarations in them for reasons other than that you want to avoid
including compat-util yourself).
Instead of using the phrase "approved headers", enumerate them as
exceptions, each labeled with its intended audiences, to avoid such
misinterpretations. The structure also makes it easier to add new
exceptions, so add the description of "t/unit-tests/test-lib.h"
being an exception only for the unit tests implementation as an
example.

The FSMonitor client code trusts the spelling of the pathnames in the
FSEvents received from the FSMonitor daemon. On case-insensitive file
systems, these OBSERVED pathnames may be spelled differently than the
EXPECTED pathnames listed in the .git/index. This causes a miss when
using `index_name_pos()` which expects the given case to be correct.
When this happens, the FSMonitor client code does not update the state
of the CE_FSMONITOR_VALID bit when refreshing the index (and before
starting to scan the worktree).
This results in modified files NOT being reported by `git status` when
there is a discrepancy in the case-spelling of a tracked file's

The previous commit special-cased get_oid_basic()'s handling of ref@{n}
for a reflog with n entries. But its special case doesn't work for
ref@{0} in an empty reflog, because read_ref_at() dies when it notices
the empty reflog!
We can make this work by special-casing this in read_ref_at(). It's
somewhat gross, for two reasons:
1. We have no reflog entry to describe in the "msg" out-parameter. So
we have to leave it uninitialized or make something up.
2. Likewise, we have no oid to put in the "oid" out-parameter. Leaving
it untouched is actually the best thing here, as all of the callers
will have initialized it with the current ref value via
repo_dwim_log(). This is rather subtle, but it is how things worked
in 6436a20284 (refs: allow @{n} to work with n-sized reflog,
2021-01-07) before we reverted it.
The key difference from 6436a20284 here is that we'll return "1" to
indicate that we _didn't_ find the requested reflog entry. Coupled with
the special-casing in get_oid_basic() in the previous commit, that's
enough to make looking up ref@{0} work, and we can flip 6436a20284's
test back to expect_success.
It also means that the call in show-branch which segfaulted with
6436a20284 (and which is now tested in t3202) remains OK. The caller
notices that we could not find any reflog entry, and so it breaks out of
its loop, showing nothing. This is different from the current behavior
of producing an error, but it's just as reasonable (and is exactly what
we'd do if you asked it to walk starting at ref@{1} but there was only 1
entry).
Thus nobody should actually look at the reflog entry info we return. But
we'll still put in some fake values just to be on the safe side, since
this is such a subtle and confusing interface. Likewise, we'll document
what's going on in a comment above the function declaration. If this
were a function with a lot of callers, the footgun would probably not be
worth it. But it has only ever had two callers in its 18-year existence,
and it seems unlikely to grow more. So let's hold our noses and let
users enjoy the convenience of a simulated ref@{0}.

The goal of 6436a20284 (refs: allow @{n} to work with n-sized reflog,
2021-01-07) was that if we have "n" entries in a reflog, we should still
be able to resolve ref@{n} by looking at the "old" value of the oldest
entry.
Commit 6436a20284 tried to put the logic into read_ref_at() by shifting
its idea of "n" by one. But we reverted that in the previous commit,
since it led to bugs in other callers which cared about the details of
the reflog entry we found. Instead, let's put the special case into the
caller that resolves @{n}, as it cares only about the oid.
read_ref_at() is even kind enough to return the "old" value from the
final reflog; it just returns "1" to signal to us that we ran off the
end of the reflog. But we can notice in the caller that we read just
enough records for that "old" value to be the one we're looking for, and
use it.
Note that read_ref_at() could notice this case, too, and just return 0.
But we don't want to do that, because the caller must be made aware that
we only found the oid, not an actual reflog entry (and the call sites in
show-branch do care about this).
There is one complication, though. When read_ref_at() hits a truncated
reflog, it will return the "old" value of the oldest entry only if it is
not the null oid. Otherwise, it actually returns the "new" value from
that entry! This bit of fudging is due to d1a4489a56 (avoid null SHA1 in
oldest reflog, 2008-07-08), where asking for "ref@{20.years.ago}" for a
ref created recently will produce the initial value as a convenience
(even though technically it did not exist 20 years ago).
But this convenience is only useful for time-based cutoffs. For
count-based cutoffs, get_oid_basic() has always simply complained about
going too far back:
$ git rev-parse HEAD@{20}
fatal: log for 'HEAD' only has 16 entries
and we should continue to do so, rather than returning a nonsense value
(there's even a test in t1508 already which covers this). So let's have
the d1a4489a56 code kick in only when doing timestamp-based cutoffs.

This reverts commit 6436a20284.
The idea of that commit is that if read_ref_at() is counting back to the
Nth reflog but the reflog is short by one entry (e.g., because it was
pruned), we can find the oid of the missing entry by looking at the
"before" oid value of the entry that comes after it (whereas before, we
looked at the "after" value of each entry and complained that we
couldn't find the one from before the truncation).
This works fine for resolving the oid of ref@{n}, as it is used by
get_oid_basic(), which does not look at any other aspect of the reflog
we found (e.g., its timestamp or message). But there's another caller of
read_ref_at(): in show-branch we use it to walk over the reflog, and we
do care about the reflog entry. And so that commit broke "show-branch
--reflog"; it shows the reflog message for ref@{0} as ref@{1}, ref@{1}
as ref@{2}, and so on.
For example, in the new test in t3202 we produce:
! [branch@{0}] (0 seconds ago) commit: three
! [branch@{1}] (0 seconds ago) commit: three
! [branch@{2}] (60 seconds ago) commit: two
! [branch@{3}] (2 minutes ago) reset: moving to HEAD^
instead of the correct:
! [branch@{0}] (0 seconds ago) commit: three
! [branch@{1}] (60 seconds ago) commit: two
! [branch@{2}] (2 minutes ago) reset: moving to HEAD^
! [branch@{3}] (2 minutes ago) commit: one
But there's another bug, too: because it is looking at the "old" value
of the reflog after the one we're interested in, it has to special-case
ref@{0} (since there isn't anything after it). That's why it doesn't
show the offset bug in the output above. But this special-case code
fails to handle the situation where the reflog is empty or missing; it
returns success even though the reflog message out-parameter has been
left uninitialized. You can't trigger this through get_oid_basic(), but
"show-branch --reflog" will pretty reliably segfault as it tries to
access the garbage pointer.
Fixing the segfault would be pretty easy. But the off-by-one problem is
inherent in this approach. So let's start by reverting the commit to
give us a clean slate to work with.
This isn't a pure revert; all of the code changes are reverted, but for
the tests:
1. We'll flip the cases in t1508 to expect_failure; making these work
was the goal of 6436a2028, and we'll want to use them for our
replacement approach.
2. There's a test in t3202 for "show-branch --reflog", but it expects
the broken output! It was added by f2463490c4 (show-branch: show
reflog message, 2021-12-02) which was fixing another bug, and I
think the author simply didn't notice that the second line showed
the wrong reflog.
Rather than fixing that test, let's replace it with one that is
more thorough (while still covering the reflog message fix from
that commit). We'll use a longer reflog, which lets us see more
entries (thus making the "off by one" pattern much more clear). And
we'll use a more recent timestamp for "now" so that our relative
dates have more resolution. That lets us see that the reflog dates
are correct (whereas when you are 4 years away, two entries that
are 60 seconds apart will have the same "4 years ago" relative
date). Because we're adjusting the repository state, I've moved
this new test to the end of the script, leaving the other tests
undisturbed.
We'll also add a new test which covers the missing reflog case;
previously it segfaulted, but now it reports the empty reflog).

This can be seen in several test cases in 't5530-upload-pack-error.sh'

The reason for this is that the abort message is defined as a string

Since caching is just an optimization, it's OK for us to skip it.
However, the current behavior is much worse: we call notes_cache_init()
which tries to look up the ref, and the low-level ref code hits a BUG(),
killing the program. Instead, we should notice before setting up the

1c56fc2084 (name-rev: pre-size buffer in get_parent_name(), 2020-02-04)
got a big performance boost in an unusual repository by calculating the
name length in advance. This is a bit awkward, as it references the

Use a memory pool to store the strings for the struct rev_name member
tip_name. Using mem_pool_strfmt() allows efficient allocation without
explicit size calculation. This simplifies the formatting part of the
code without giving up performance:
Benchmark 1: ./git_2.44.0 -C ../chromium/src name-rev --all
Time (mean ± σ): 1.231 s ± 0.013 s [User: 1.082 s, System: 0.136 s]

Don't bother discarding the memory pool just before exiting. The effort
for that would be very low, but actually measurable in the above
example, with no benefit to users. At least UNLEAK it to calm down leak

Add a function for building a string, printf style, using a memory pool.
It uses the free space in the current block in the first attempt. If
that suffices then the result can already be used without copying or
reformatting.
For strings that are significantly shorter on average than the block
size (ca. 1 MiB by default) this is the case most of the time, leading
to a better perfomance than a solution that doesn't access mem-pool
internals.

Using strncmp() and strlen() to check whether a string starts with
another one requires repeating the prefix candidate. Use starts_with()
instead, which reduces repetition and is more readable.

These two header files are included from ordinary source files that
already include <git-compat-util.h> as the first header file as they
should. There is no need to include the compat-util in these
headers.
"make hdr-check" is not affected, as it is designed to assume that
what <git-compat-util.h> offers is available to everybody without
being included.

In af626ac0e0 (pack-bitmap: enable reuse from all bitmapped packs,
2023-12-14), the documentation for `pack.allowPackReuse` was amended to
include its effect when set to "multi".
This split the documentation into two paragraphs, but did not de-dent
the second paragraph on the right-hand side of a line-continuation
marker. This causes the rendered documentation to appear oddly, where
the second paragraph is treated as a <pre> block when rendered as HTML.
Fix this by correctly removing the indentation on the second paragraph.
