We try to write "|| return 1" (or "|| exit 1" in a subshell) at the
end of a sequence of &&-chained command in a loop of our tests, so
that a failure of any step during the earlier iteration of the loop
can properly be caught.
There is one loop in this test script that is used to compute the
expected result, that will be later compared with an actual output
produced by the "test-tool pack-mtimes" command. This particular
loop, however, is placed on the upstream side of a pipe, whose
non-zero exit code does not get noticed.
Emit a line that will never be produced by the "test-tool pack-mtimes"
to cause the later comparison to fail. As we use test_cmp to compare
this "expected output" file with the "actual output", the "error
message" we are emitting into the expected output stream will stand
out and shown to the tester.

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

This test wants to verify that `git blame` errors out when asked to
blame a file _not_ in the sparse checkout. However, the very first file
it asks to blame _is_ present in the checkout, thus `test_must_fail git
blame $file` gives an unexpected result (the "blame" succeeds). This
problem went unnoticed because the test invokes `test_must_fail git
blame $file` in loop but forgets to break out of the loop early upon
failure, thus the failure gets swallowed.
Fix the test by having it not ask to blame a file present in the sparse
checkout, and instead only blame files not present, as intended. While
at it, also add the missing `|| return 1` which allowed this bug to go
unnoticed.

The breaks in the &&-chain in this test went unnoticed because the

recognizes broken &&-chains at the top-level; it does not work within
`{...}` groups, `(...)` subshells, `$(...)` substitutions, or within
bodies of compound statements, such as `if`, `for`, `while`, `case`,
etc. Furthermore, `chainlint.sed` detects broken &&-chains only in

The entry point to the patience-diff algorithm takes two mmfile_t
structs with the original file contents, but it doesn't actually do
anything useful with them. This is similar to the case recently cleaned
up in the histogram code via f1d019071e (xdiff: drop unused mmfile
parameters from xdl_do_histogram_diff(), 2022-08-19), but there's a bit
more subtlety going on.
We pass them into the recursive patience_diff(), which in turn passes
them into fill_hashmap(), which stuffs the pointers into a struct. But
the only thing which reads the struct fields is our recursion into
patience_diff()!
So it's unlikely that something like -Wunused-parameter could find this
case: it would have to detect the circular dependency caused by the
recursion (not to mention tracing across struct field assignments).
But once found, it's easy to have the compiler confirm what's going on:
1. Drop the "file1" and "file2" fields from the hashmap struct
definition. Remove the assignments in fill_hashmap(), and
temporarily substitute NULL in the recursive call to
patience_diff(). Compiling shows that no other code touched those
fields.
2. Now fill_hashmap() will trigger -Wunused-parameter. Drop "file1"
and "file2" from its definition and callsite.
3. Now patience_diff() will trigger -Wunused-parameter. Drop them
there, too. One of the callsites is the recursion with our
NULL values, so those temporary values go away.
4. Now xdl_do_patience_diff() will trigger -Wunused-parameter. Drop
them there. And we're done.

Traditionally, reflog messages were never translated, in particular not
on storage.
Due to the switch of more parts of git to the sequencer, old changes in
the sequencer code may lead to recent changes in git's behaviour. E.g.:
c28cbc5ea6 ("sequencer: mark action_name() for translation", 2016-10-21)
marked several uses of `action_name()` for translation. Recently, this
lead to a partially translated reflog:
`rebase: fast-forward` is translated (e.g. in de to `Rebase: Vorspulen`)
whereas other reflog entries such as `rebase (pick):` remain
untranslated as they should be.
Change the relevant line in the sequencer so that this reflog entry
remains untranslated, as well.

Commit 66b209b86a ("merge-ort: implement CE_SKIP_WORKTREE handling with
conflicted entries", 2021-03-20) added some code for merge-ort to handle
conflicted and skip_worktree entries in general. Included in this was
an ugly hack for dealing with present-despite-skipped entries and a
testcase (t6428.2) specific to that hack, since at that time users could
accidentally get files into that state when using a sparse checkout.
However, with the merging of 82386b4496 ("Merge branch
'en/present-despite-skipped'", 2022-03-09), that class of problems was
addressed globally and in a much cleaner way. As such, the
present-despite-skipped hack in merge-ort is no longer needed and can
simply be removed.
No additional testcase is needed here; t6428.2 was written to test the
necessary functionality and is being kept. The fact that this test
continues to pass despite the code being removed shows that the extra
code is no longer necessary.

Make the search for repository and enlistment root in
'setup_enlistment_directory()' more constrained to simplify behavior and
adhere to 'GIT_CEILING_DIRECTORIES'.
Previously, 'setup_enlistment_directory()' would check whether the provided
path (or current working directory) '<dir>' or its subdirectory '<dir>/src'
was a repository root. If not, the process would repeat on the parent of
'<dir>' until the repository was found or it reached the root of the
filesystem. This meant that a user could specify a path *anywhere* inside an
enlistment (including paths not in the repository contained within the
enlistment) and it would be found.
The downside to this process is that the search would not account for
'GIT_CEILING_DIRECTORIES', so the upward search could result in modifying
repository contents past 'GIT_CEILING_DIRECTORIES'. Similarly, operations
like 'scalar delete' could end up unintentionally deleting the parent of a
repo if its root was named 'src'.
To make this 'setup_enlistment_directory()' both adhere to
'GIT_CEILING_DIRECTORIES' and avoid unwanted deletions, the search for an
enlistment directory is simplified to:
- if '<dir>/src' is a repository root, '<dir>' is the enlistment root
- if '<dir>' is either the repository root or contained within a repository,
the repository root is the enlistment root
Now, only 'setup_git_directory()' (called by 'setup_enlistment_directory()')
searches upwards from the 'scalar' specified path, enforcing
'GIT_CEILING_DIRECTORIES' in the process. Additionally, 'scalar delete
<dir>/src' will not delete '<dir>' (if users would like to delete it, they
can still specify the enlistment root with 'scalar delete <dir>'). This is
true of any 'scalar' operation; users can invoke 'scalar' on the enlistment
root, but paths must otherwise be inside the repository to be valid.
To help clarify the updated behavior, new tests are added to
't9099-scalar.sh'.
Finally, this change leaves 'strbuf_parent_directory()' with only a single,
WIN32-specific caller in 'delete_enlistment()'. Rather than wrap
'strbuf_parent_directory()' in '#ifdef WIN32' to avoid the "unused function"
compiler error, move the contents of 'strbuf_parent_directory()' into
'delete_enlistment()' and remove the function.
