Earlier we marked that this patch-id test is leak-sanitizer clean,
but if we read the test script carefully, it is merely because we
have too many invocations of commands in the "git log" family on the
upstream side of the pipe, hiding breakages from them.
Split the pipeline so that breakages from these commands can be
caught (not limited to aborts due to leak-sanitizer) and unmark
the script as not passing the test with leak-sanitizer in effect.

"git worktree add" showed "Preparing worktree" message to the
standard output stream, but when it failed, the message from die()
went to the standard error stream. Depending on the order the

messages to the standard error stream.

The sparse_dir_matches_path() method compares a cache entry that is a
sparse directory entry against a 'struct traverse_info *info' and a
'struct name_entry *p' to see if the cache entry has exactly the right
name for those other inputs.
This method was introduced in 523506d (unpack-trees: unpack sparse
directory entries, 2021-07-14), but included a significant mistake. The
path comparisons used 'info->name' instead of 'info->traverse_path'.
Since 'info->name' only stores a single tree entry name while
'info->traverse_path' stores the full path from root, this method does
not work when 'info' is in a subdirectory of a directory. Replacing the
right strings and their corresponding lengths make the method work
properly.
The previous change included a failing test that exposes this issue.
That test now passes. The critical detail is that as we go deep into
unpack_trees(), the logic for merging a sparse directory entry with a
tree entry during 'git checkout' relies on this
sparse_dir_matches_path() in order to avoid calling
traverse_trees_recursive() during unpack_callback() in this hunk:
if (!is_sparse_directory_entry(src[0], names, info) &&
traverse_trees_recursive(n, dirmask, mask & ~dirmask,
names, info) < 0) {
return -1;
}
For deep paths, the short-circuit never occurred and
traverse_trees_recursive() was being called incorrectly and that was
causing other strange issues. Specifically, the error message from the
now-passing test previously included this:
error: Your local changes to the following files would be overwritten by checkout:
deep/deeper1/deepest2/a
deep/deeper1/deepest3/a
Please commit your changes or stash them before you switch branches.
Aborting
These messages occurred because the 'current' cache entry in
twoway_merge() was showing as NULL because the index did not contain
entries for the paths contained within the sparse directory entries. We
instead had 'oldtree' given as the entry at HEAD and 'newtree' as the
entry in the target tree. This led to reject_merge() listing these
paths.
Now that sparse_dir_matches_path() works the same for deep paths as it
does for shallow depths, the rest of the logic kicks in to properly
handle modifying the sparse directory entries as designed.

Extend the repository data in the setup of t1092 to include more
directories within two parent directories. This reproduces a bug found
by users of the sparse index feature with suitably-complicated
sparse-checkout definitions.
Add a failing test that fails in its first 'git checkout deepest' run in
the sparse index case with this error:
error: Your local changes to the following files would be overwritten by checkout:
deep/deeper1/deepest2/a
deep/deeper1/deepest3/a
Please commit your changes or stash them before you switch branches.
Aborting
The next change will fix this error, and that fix will make it clear why
the extra depth is necessary for revealing this bug. The assignment of
the sparse-checkout definition to include deep/deeper1/deepest as a
sibling directory is important to ensure that deep/deeper1 is not a
sparse directory entry, but deep/deeper1/deepest2 is.

The order in which the stdout and stderr streams are flushed is not
guaranteed to be the same across platforms or `libc` implementations.
This lack of determinism can lead to anomalous and potentially confusing
output if normal (stdout) output is flushed after error (stderr) output.
For instance, the following output which clearly indicates a failure due
to a fatal error:
% git worktree add ../foo bar
Preparing worktree (checking out 'bar')
fatal: 'bar' is already checked out at '.../wherever'
has been reported[1] on Microsoft Windows to appear as:
% git worktree add ../foo bar
fatal: 'bar' is already checked out at '.../wherever'
Preparing worktree (checking out 'bar')
which may confuse the reader into thinking that the command somehow
recovered and ran to completion despite the error.
This problem crops up because the "chatty" status message "Preparing
worktree" is sent to stdout, whereas the "fatal" error message is sent
to stderr. One way to fix this would be to flush stdout manually before
git-worktree reports any errors to stderr.
However, common practice in Git is for "chatty" messages to be sent to
stderr. Therefore, a more appropriate fix is to adjust git-worktree to
conform to that practice by sending its "chatty" messages to stderr
rather than stdout as is currently the case.
There may be concern that relocating messages from stdout to stderr
could break existing tooling, however, these messages are already
internationalized, thus are unstable. And, indeed, the "Preparing
worktree" message has already been the subject of somewhat significant
changes in 2c27002a0a (worktree: improve message when creating a new
worktree, 2018-04-24). Moreover, there is existing precedent, such as
68b939b2f0 (clone: send diagnostic messages to stderr, 2013-09-18) which
likewise relocated "chatty" messages from stdout to stderr for
git-clone.

We have some tests that read from files in .git/logs/ hierarchy
when checking if correct reflog entries are created, but that is
too specific to the files backend. Other backends like reftable
may not store its reflog entries in such a "one line per entry"
format.
Update for-each-reflog-ent test helper to produce output that
is identical to lines in a reflog file files backend uses.
That way, (1) the current tests can be updated to use the test
helper to read the reflog entries instead of (parts of) reflog
files, and perform the same inspection for correctness, and (2)
when the ref backend is swapped to another backend, the updated
test can be used as-is to check the correctness.
Adapt t1400 to use the for-each-reflog-ent test helper.

BAIL_OUT() is meant to abort the whole test run and print a message with
a standard prefix that can be parsed to stdout. Since for every test the
normal fd`s are redirected in test_eval_ this output would not be seen
when used within the context of a test or prereq like we do in
test_have_prereq(). To make this function work in these contexts we move
the setup of the fd aliases a few lines up before the first use of
BAIL_OUT() and then have this function always print to the alias.

"zdiff3" is identical to ordinary diff3 except that it allows compaction
of common lines on the two sides of history at the beginning or end of
the conflict hunk. For example, the following diff3 conflict:
1
2
3
4
<<<<<<
A
B
C
D
E
||||||
5
6
======
A
X
C
Y
E
>>>>>>
7
8
9
has common lines 'A', 'C', and 'E' on the two sides. With zdiff3, one
would instead get the following conflict:
1
2
3
4
A
<<<<<<
B
C
D
||||||
5
6
======
X
C
Y
>>>>>>
E
7
8
9
Note that the common lines, 'A', and 'E' were moved outside the
conflict. Unlike with the two-way conflicts from the 'merge'
conflictStyle, the zdiff3 conflict is NOT split into multiple conflict
regions to allow the common 'C' lines to be shown outside a conflict,
because zdiff3 shows the base version too and the base version cannot be
reasonably split.
Note also that the removing of lines common to the two sides might make
the remaining text inside the conflict region match the base text inside
the conflict region (for example, if the diff3 conflict had '5 6 E' on
the right side of the conflict, then the common line 'E' would be moved
outside and both the base and right side's remaining conflict text would
be the lines '5' and '6'). This has the potential to surprise users and
make them think there should not have been a conflict, but there
definitely was a conflict and it should remain.

The `--exec <cmd>` is documented as
Append "exec <cmd>" after each line creating a commit in the final
history.
...
If --autosquash is used, "exec" lines will not be appended for the
intermediate commits, and will only appear at the end of each
squash/fixup series.
Unfortunately, it would also add exec commands after non-pick
operations, such as 'no-op', which could be seen for example with
git rebase -i --exec true HEAD
todo_list_add_exec_commands() intent was to insert exec commands after
each logical pick, while trying to consider a chains of fixup and squash
commits to be part of the pick before it. So it would keep an 'insert'
boolean tracking if it had seen a pick or merge, but not write the exec
command until it saw the next non-fixup/squash command. Since that
would make it miss the final exec command, it had some code that would
check whether it still needed to insert one at the end, but instead of a
simple
if (insert)
it had a
if (insert || <condition that is always true>)
That's buggy; as per the docs, we should only add exec commands for
lines that create commits, i.e. only if insert is true. Fix the
conditional.
There was one testcase in the testsuite that we tweak for this change;
it was introduced in 54fd3243da ("rebase -i: reread the todo list if
`exec` touched it", 2017-04-26), and was merely testing that after an
exec had fired that the todo list would be re-read. The test at the
time would have worked given any revision at all, though it would only
work with 'HEAD' as a side-effect of this bug. Since we're fixing this
bug, choose something other than 'HEAD' for that test.
Finally, add a testcase that verifies when we have no commits to pick,
that we get no exec lines in the generated todo list.
