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).

The textconv caching system uses git-notes to store its cache entries.
But if you're using "diff --no-index" outside of a repository, then
obviously that isn't going to work.
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
cache that it there's no repository, and just silently skip it.

While the git-reflog(1) command has subcommands to show reflog entries

would allow the user to enumerate all existing reflogs. This makes it
quite hard to discover which reflogs a repository has. While this can
be worked around with the "files" backend by enumerating files in the
".git/logs" directory, users of the "reftable" backend don't enjoy such
a luxury.

The ref and reflog iterators share much of the same underlying code to
iterate over the corresponding entries. This results in some weird code
because the reflog iterator also exposes an object ID as well as a flag
to the callback function. Neither of these fields do refer to the reflog
though -- they refer to the corresponding ref with the same name. This
is quite misleading. In practice at least the object ID cannot really be
implemented in any other way as a reflog does not have a specific object
ID in the first place. This is further stressed by the fact that none of
the callbacks except for our test helper make use of these fields.
Split up the infrastucture so that ref and reflog iterators use separate
callback signatures. This allows us to drop the nonsensical fields from
the reflog iterator.
Note that internally, the backends still use the same shared infra to
iterate over both types. As the backends should never end up being
called directly anyway, this is not much of a problem and thus kept
as-is for simplicity's sake.

We use a directory iterator to return reflogs via the reflog iterator.
This iterator returns entries in the same order as readdir(3P) would and
will thus yield reflogs with no discernible order.
Set the new `DIR_ITERATOR_SORTED` flag that was introduced in the
preceding commit so that the order is deterministic. While the effect of
this can only been observed in a test tool, a subsequent commit will

The `--trust-exit-code` option for git-diff-tool(1) was introduced via
2b52123fcf (difftool: add support for --trust-exit-code, 2014-10-26).
When set, it makes us return the exit code of the invoked diff tool when
diffing multiple files. This patch didn't change the code path where
`--dir-diff` was passed because we already returned the exit code of the
diff tool unconditionally in that case.
This was changed a month later via c41d3fedd8 (difftool--helper: add
explicit exit statement, 2014-11-20), where an explicit `exit 0` was
added to the end of git-difftool--helper.sh. While the stated intent of
that commit was merely a cleanup, it had the consequence that we now
to ignore the exit code of the diff tool when `--dir-diff` was set. This
change in behaviour is thus very likely an unintended side effect of
this patch.
Now there are two ways to fix this:
- We can either restore the original behaviour, which unconditionally
returned the exit code of the diffing tool when `--dir-diff` is
passed.
- Or we can make the `--dir-diff` case respect the `--trust-exit-code`
flag.
The fact that we have been ignoring exit codes for 7 years by now makes
me rather lean towards the latter option. Furthermore, respecting the
flag in one case but not the other would needlessly make the user
interface more complex.
Fix the bug so that we also honor `--trust-exit-code` for dir diffs and
adjust the documentation accordingly.

Commit 97e9d0b78a (trailer: find the end of the log message, 2023-10-20)
combined two code paths for finding the end of the log message. For the
"no_divider" case, we used to use find_trailer_end(), and that has now
been rolled into find_end_of_log_message(). But there's a regression;
that function returns early when no_divider is set, returning the whole
string.
That's not how find_trailer_end() behaved. Although it did skip the
"---" processing (which is what "no_divider" is meant to do), we should
still respect ignored_log_message_bytes(), which covers things like
comments, "commit -v" cut lines, and so on.
The bug is actually in the interpret-trailers command, but the obvious
way to experience it is by running "commit -v" with a "--trailer"
option. The new trailer will be added at the end of the verbose diff,
rather than before it (and consequently will be ignored entirely, since
everything after the diff's intro scissors line is thrown away).
I've added two tests here: one for interpret-trailers directly, which
shows the bug via the parsing routines, and one for "commit -v".
The fix itself is pretty simple: instead of returning early, no_divider
just skips the "---" handling but still calls ignored_log_message_bytes().

Our lib-credential.sh library comes with a "clean" function that removes
all of the credentials used in its tests (to avoid leaving cruft in
system credential storage). But it's easy to add a test that uses a new
credential but forget to add it to the clean function. E.g., the case
fixed by 83e6eb7d7a (t/lib-credential: clean additional credential,
2024-02-15).
We should be able to catch this automatically, but it's a little tricky.
We can't just compare the contents of the helper's storage before and
after the test run, because there isn't a way to ask a helper to dump
all of its storage. And in most cases we don't have direct access to the
underlying storage (since the whole point of the helper is to abstract
that away). We can work around that by using our own "store" helper,
since we can directly inspect its state by looking at its on-disk file.
But there's a catch: the "store" helper doesn't support features like
caching or expiration, so using it naively fails tests (and skipping
those tests would give us incomplete coverage). Implementing all of
those features would be non-trivial. But we can hack around that by
overriding the "check" function used by the tests to turn most requests
into noop success (except for "approve" requests, which actually store
things).
And then at the end we can check that running the "clean" function takes
us back to an empty state.
Note that because we've skipped any tests that erase credentials
(because of our noop check function), the state we see at cleanup time
may be larger than it would be normally. That's OK. The point of the
clean function is to clean up any cruft we _might_ have left in place,
so we're just being doubly thorough.
The way this is bolted onto t0303 feels a little messy. But it's really
the best place to do it, because then we know that it is running the
exact sequence of tests that we'd use for testing a real external
helper. In a normal run of "make test" it currently does nothing (the
idea is that you run it manually after pointing it at some helper
program). But now with this patch, "make test" will sanity-check the
script itself.

Some of the tests in t1404 exercise whether Git correctly aborts
transactions when there is a directory/file conflict with ref names.
While these tests are all marked to require the "files" backend, they do
in fact apply to the "reftable" backend as well.
This may not make much sense on the surface: D/F conflicts only exist
because the "files" backend uses the filesystem to store loose refs, and
thus the restriction theoretically shouldn't apply to the "reftable"
backend. But for now, the "reftable" backend artificially restricts the
creation of such conflicting refs so that it is a drop-in replacement
for the "files" backend. This also ensures that the "reftable" backend
can easily be used on the server side without causing issues for clients
which only know to use the "files" backend.
The only difference between the "files" and "reftable" backends is a
slightly different error message. Adapt the tests to accomodate for this
difference and remove the REFFILES prerequisite so that we start testing
with both backends.

* vn/rebase-with-cherry-pick-authorship:
sequencer: unset GIT_CHERRY_PICK_HELP for 'exec' commands
The sequencer machinery does not use the ref API and instead
records names of certain objects it needs for its correct operation
in temporary files, which makes these objects susceptible to loss
by garbage collection. These temporary files have been added as
starting points for reachability analysis to fix this.
* pw/gc-during-rebase:
prune: mark rebase autostash and orig-head as reachable
The helper functions test_path_is_* provide better debugging
information than test -d/-e/-f.
Replace "if ! test -d then <error message>" and "test -d" with
"test_path_is_dir" at places where we check for existent directories.
Replace "test -f" with "test_path_is_file" at places where we check
for existent files.
Replace "test ! -e" and "if test -d then <error message>" with
"test_path_is_missing" where we check for non-existent directories.

"git stash" sometimes was silent even when it failed due to
unwritable index file, which has been corrected.
* ps/report-failure-from-git-stash:
builtin/stash: report failure to write to index
"git diff --no-index file1 file2" segfaulted while invoking the
external diff driver, which has been corrected.
* jk/diff-external-with-no-index:
diff: handle NULL meta-info when spawning external diff
"git diff --no-rename A B" did not disable rename detection but did
not trigger an error from the command line parser.
* rs/parse-options-with-keep-unknown-abbrev-fix:
parse-options: simplify positivation handling
parse-options: fully disable option abbreviation with PARSE_OPT_KEEP_UNKNOWN
Rename detection logic ignored the final line of a file if it is an
incomplete line.
* en/diffcore-delta-final-line-fix:
diffcore-delta: avoid ignoring final 'line' of file
Update to a new feature recently added, "git show-ref --exists".
* tc/show-ref-exists-fix:
builtin/show-ref: treat directory as non-existing in --exists
The mechanism to report the filename in the source code, used by
the unit-test machinery, assumed that the compiler expanded __FILE__
to the path to the source given to the $(CC), but some compilers
give full path, breaking the output. This has been corrected.
* jc/unit-tests-make-relative-fix:
unit-tests: do show relative file paths on non-Windows, too
