During Git 2.35 timeframe, daf1d828 (reflog expire: don't use
lookup_commit_reference_gently(), 2021-12-22) replaced a call to
lookup_commit_reference_gently() with a call to lookup_commit().
What it failed to consider was that our refs do not necessarily
point at commits (most notably, we have annotated and signed tags),
and more importantly that lookup_commit() does not dereference a tag
to return a commit; instead it returns NULL when a tag is given.
Since the commit returned is used as a starting point for the
reachability check, this ejected the commits that are reachable only
by an annotated tag out of the set of reachable commits, breaking
the computation to correctly implement the "--expire-unreachable"
option. We also started giving an error message that the API
function expected to be fed a commit object.
This problem hasn't been reported or noticed for a long time,
probably because the "refs/tags/" hierarchy by default is not
covered by reflogs, as nobody usually moves tags.
Revert the change to correctly find the commit pointed at by the ref
to restore the previous behaviour, but do so only in a more modern
codebase, as we had significant code churn since then and it is not
grave enough to worry about for older maintenance tracks.

While the git-reflog(1) command has subcommands to show reflog entries
or check for reflog existence, it does not have any subcommands that
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.
Introduce a new subcommand `git reflog list` that lists all reflogs the
repository knows of to fill this gap.

Another step to deprecate test_i18ngrep.
* jc/test-i18ngrep:
tests: teach callers of test_i18ngrep to use test_grep
test framework: further deprecate test_i18ngrep
They are equivalents and the former still exists, so as long as the
only change this commit makes are to rewrite test_i18ngrep to
test_grep, there won't be any new bug, even if there still are
callers of test_i18ngrep remaining in the tree, or when merged to
other topics that add new uses of test_i18ngrep.
This patch was produced more or less with
git grep -l -e 'test_i18ngrep ' 't/t[0-9][0-9][0-9][0-9]-*.sh' |
xargs perl -p -i -e 's/test_i18ngrep /test_grep /'
and a good way to sanity check the result yourself is to run the
above in a checkout of c4603c1c (test framework: further deprecate
test_i18ngrep, 2023-10-31) and compare the resulting working tree
contents with the result of applying this patch to the same commit.
You'll see that test_i18ngrep in a few t/lib-*.sh files corrected,
in addition to the manual reproduction.

33d7bdd645 (builtin/reflog.c: use parse-options api for expire, delete
subcommands, 2022-01-06) broke the option --single-worktree of git
reflog expire and added a non-printable short flag for it, presumably by
accident. While before it set the variable "all_worktrees" to 0, now it
sets it to 1, its default value. --no-single-worktree is required now
to set it to 0.
Fix it by replacing the variable with one that has the opposite meaning,
to avoid the negation and its potential for confusion. The new variable
"single_worktree" directly captures whether --single-worktree was given.
Also remove the unprintable short flag SOH (start of heading) because it
is undocumented, hard to use and is likely to have been added by mistake
in connection with the negation bug above.

Whenever a user runs `git reflog expire --stale-fix`, the most likely
reason is that their repository is at least _somewhat_ corrupt. Which
means that it is more than just possible that some objects are missing.
If that is the case, that can currently let the command abort through
the phase where it tries to mark all reachable objects.
Instead of adding insult to injury, let's be gentle and continue as best
as we can in such a scenario, simply by ignoring the missing objects and

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \

We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\

When gc.reflogExpire and gc.reflogExpireUnreachable are set to "never"

pointlessly looping over all the reflogs.
However, as an earlier change to add a test for the "points nowhere"
warning shows even in such a mode we might want to print out a
warning.
So while it's conceivable to implement this, I don't think it's worth
it. It's going to be too easy to inadvertently add some flag that'll
make the expiry happen anyway, and even with "never" we'd like to see
all the lines we're going to keep.

Using 'test_must_be_empty' is shorter and more idiomatic than
>empty &&
test_cmp empty out
as it saves the creation of an empty file. Furthermore, sometimes the
expected empty file doesn't have such a descriptive name like 'empty',
and its creation is far away from the place where it's finally used
for comparison (e.g. in 't7600-merge.sh', where two expected empty
files are created in the 'setup' test, but are used only about 500
lines later).
These cases were found by instrumenting 'test_cmp' to error out the
test script when it's used to compare empty files, and then converted
manually.
Note that even after this patch there still remain a lot of cases
where we use 'test_cmp' to check empty files:
- Sometimes the expected output is not hard-coded in the test, but
'test_cmp' is used to ensure that two similar git commands produce
the same output, and that output happens to be empty, e.g. the
test 'submodule update --merge - ignores --merge for new
submodules' in 't7406-submodule-update.sh'.
- Repetitive common tasks, including preparing the expected results
and running 'test_cmp', are often extracted into a helper
function, and some of this helper's callsites expect no output.
- For the same reason as above, the whole 'test_expect_success'
block is within a helper function, e.g. in 't3070-wildmatch.sh'.
- Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update
(-p)' in 't9400-git-cvsserver-server.sh'.

If a repository contains more than one root commit, then its HEAD
reflog may contain multiple "creation events", i.e. entries whose
"from" value is the null sha1. Listing such a reflog currently stops
prematurely at the first such entry, even when the reflog still
contains older entries. This can scare users into thinking that their
reflog got truncated after 'git checkout --orphan'.
Continue walking the reflog past such creation events based on the
preceeding reflog entry's "new" value.
The test 'symbolic-ref writes reflog entry' in t1401-symbolic-ref
implicitly relies on the current behavior of the reflog walker to stop
at a root commit and thus to list only the reflog entries that are
relevant for that test. Adjust the test to explicitly specify the
number of relevant reflog entries to be listed.

git reflog (ab)uses the log machinery to display its list of log
entries. To do so it must fake commit parent information for the log
walker.
For refs in refs/heads this is no problem, as they should only ever
point to commits. Tags and other refs however can point to anything,
thus their reflog may contain non-commit objects.
To avoid segfaulting, we check whether reflog entries are commits before
feeding them to the log walker and skip any non-commits. This means that
git reflog output will be incomplete for such refs, but that's one step
up from segfaulting. A more complete solution would be to decouple git
reflog from the log walker machinery.

The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.
The backquoted form is the traditional method for command
substitution, and is supported by POSIX. However, all but the
simplest uses become complicated quickly. In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.
The patch was generated by:
for _f in $(find . -name "*.sh")
do
perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}"
done
and then carefully proof-read.

Alternate refs backends might store reflogs somewhere other than
.git/logs. Change most test code that directly accesses .git/logs to
instead use git reflog commands.
There are still a few tests which need direct access to reflogs: to
check reflog permissions, to manually create reflogs from scratch, to
save/restore reflogs, to check the format of raw reflog data, and to
remove not just reflog contents, but the reflogs themselves. All cases
which don't need direct access have been modified.

The code that reads the reflog from the newer to the older entries
did not handle an entry that crosses a boundary of block it uses to
read them correctly.
* jk/for-each-reflog-ent-reverse:
for_each_reflog_ent_reverse: turn leftover check into assertion
for_each_reflog_ent_reverse: fix newlines on block boundaries
When we read a reflog file in reverse, we read whole chunks
of BUFSIZ bytes, then loop over the buffer, parsing any
lines we find. We find the beginning of each line by looking
for the newline from the previous line. If we don't find
one, we know that we are either at the beginning of
the file, or that we have to read another block.
In the latter case, we stuff away what we have into a
strbuf, read another block, and continue our parse. But we
missed one case here. If we did find a newline, and it is at
the beginning of the block, we must also stuff that newline
into the strbuf, as it belongs to the block we are about to
read.
The minimal fix here would be to add this special case to
the conditional that checks whether we found a newline.
But we can make the flow a little clearer by rearranging a
bit: we first handle lines that we are going to show, and
then at the end of each loop, stuff away any leftovers if
necessary. That lets us fold this special-case in with the
more common "we ended in the middle of a line" case.

Two tests recently added to t1410 create branches "a" and
"a/b" to test d/f conflicts on reflogs. Earlier, unrelated
tests in that script create the path "A/B" in the working
tree. There's no conflict on a case-sensitive filesystem,
but on a case-insensitive one, "git log" will complain that
"a/b" is both a revision and a working tree path.
We could fix this by using a "--" to disambiguate, but we
are probably better off using names that are less confusing
to make it more clear that they are unrelated to the working
tree files. This patch turns "a/b" into "one/two".

Corner-case bugfixes for "git fetch" around reflog handling.
* jk/fetch-reflog-df-conflict:
ignore stale directories when checking reflog existence
fetch: load all default config at startup
When we update a ref, we have two rules for whether or not
we actually update the reflog:
1. If the reflog already exists, we will always append to
it.
2. If log_all_ref_updates is set, we will create a new
reflog file if necessary.
We do the existence check by trying to open the reflog file,
either with or without O_CREAT (depending on log_all_ref_updates).
If it fails, then we check errno to see what happened.
If we were not using O_CREAT and we got ENOENT, the file
doesn't exist, and we return success (there isn't a reflog
already, and we were not told to make a new one).
If we get EISDIR, then there is likely a stale directory
that needs to be removed (e.g., there used to be "foo/bar",
it was deleted, and the directory "foo" was left. Now we
want to create the ref "foo"). If O_CREAT is set, then we
catch this case, try to remove the directory, and retry our
open. So far so good.
But if we get EISDIR and O_CREAT is not set, then we treat
this as any other error, which is not right. Like ENOENT,
EISDIR is an indication that we do not have a reflog, and we
should silently return success (we were not told to create
it). Instead, the current code reports this as an error, and
we fail to update the ref at all.
Note that this is relatively unlikely to happen, as you
would have to have had reflogs turned on, and then later
turned them off (it could also happen due to a bug in fetch,
but that was fixed in the previous commit). However, it's
quite easy to fix: we just need to treat EISDIR like ENOENT
for the non-O_CREAT case, and silently return (note that
this early return means we can also simplify the O_CREAT
case).
Our new tests cover both cases (O_CREAT and non-O_CREAT).
The first one already worked, of course.

Change checkout.c to check if a ref exists instead of checking if a loose ref
file exists when deciding if to delete an orphaned log file. Otherwise, if a
ref only exists as a packed ref without a corresponding loose ref for the
currently checked out branch, we risk that the reflog will be deleted when we
switch to a different branch.
Update the reflog tests to check for this bug.
The following reproduces the bug:
$ git init-db
$ git config core.logallrefupdates true
$ git commit -m Initial --allow-empty
[master (root-commit) bb11abe] Initial
$ git reflog master
[8561dcb master@{0}: commit (initial): Initial]
$ find .git/{refs,logs} -type f | grep master
[.git/refs/heads/master]
[.git/logs/refs/heads/master]
$ git branch foo
$ git pack-refs --all
$ find .git/{refs,logs} -type f | grep master
[.git/logs/refs/heads/master]
$ git checkout foo
$ find .git/{refs,logs} -type f | grep master
... reflog file is missing ...
$ git reflog master
... nothing ...

Breaks in a test assertion's && chain can potentially hide
failures from earlier commands in the chain.
Commands intended to fail should be marked with !, test_must_fail, or
test_might_fail. The examples in this patch do not require that.
