Add a new option "--format" that outputs index entries
informations in a custom format, taking inspiration
from the option with the same name in the `git ls-tree`
command.
"--format" cannot used with "-s", "-o", "-k", "-t",
" --resolve-undo","--deduplicate" and "--eol".

Previously, if the user:
* Had no local changes before starting the merge
* A merge strategy makes changes to the working tree/index but returns
with exit status 2
Then we'd call restore_state() to clean up the changes and either let
the next merge strategy run (if there is one), or exit telling the user
that no merge strategy could handle the merge. Unfortunately,
restore_state() did not clean up the changes as expected; that function
was a no-op if the stash was a null, and the stash would be null if
there were no local changes before starting the merge. So, instead of
"Rewinding the tree to pristine..." as the code claimed, restore_state()
would leave garbage around in the index and working tree (possibly
including conflicts) for either the next merge strategy or for the user
after aborting the merge. And in the case of aborting the merge, the
user would be unable to run "git merge --abort" to get rid of the
unintended leftover conflicts, because the merge control files were not
written as it was presumed that we had restored to a clean state
already.
Fix the main problem by making sure that restore_state() only skips the
stash application if the stash is null rather than skipping the whole
function.
However, there is a secondary problem -- since merge.c forks
subprocesses to do the cleanup, the in-memory index is left out-of-sync.
While there was a refresh_cache(REFRESH_QUIET) call that attempted to
correct that, that function would not handle cases where the previous
merge strategy added conflicted entries. We need to drop the index and
re-read it to handle such cases.
(Alternatively, we could stop forking subprocesses and instead call some
appropriate function to do the work which would update the in-memory
index automatically. For now, just do the simple fix.)
Also, add a testcase checking this, one for which the octopus strategy
fails on the first commit it attempts to merge, and thus which it
cannot handle at all and must completely bail on (as per the "exit 2"
code path of commit 98efc8f3d8 ("octopus: allow manual resolve on the
last round.", 2006-01-13)).

Merge strategies can:
* succeed with a clean merge
* succeed with a conflicted merge
* fail to handle the given type of merge
If one is thinking in terms of automatic mergeability, they would use
the word "fail" instead of "succeed" for the second bullet, but I am
focusing here on ability of the merge strategy to handle the given
inputs, not on whether the given inputs are mergeable. The third
category is about the merge strategy failing to know how to handle the
given data; examples include:
* Passing more than 2 branches to 'recursive' or 'ort'
* Passing 2 or fewer branches to 'octopus'
* Trying to do more complicated merges with 'resolve' (I believe
directory/file conflicts will cause it to bail.)
* Octopus running into a merge conflict for any branch OTHER than
the final one (see the "exit 2" codepath of commit 98efc8f3d8
("octopus: allow manual resolve on the last round.", 2006-01-13))
That final one is particularly interesting, because it shows that the
merge strategy can muck with the index and working tree, and THEN bail
and say "sorry, this strategy cannot handle this type of merge; use
something else".
Further, we do not currently expect the individual strategies to clean
up after themselves, but instead expect builtin/merge.c to do so. For
it to be able to, it needs to save the state before trying the merge
strategy so it can have something to restore to. Therefore, remove the
shortcut bypassing the save_state() call.
There is another bug on the restore_state() side of things, so no
testcase will be added until the next commit when we have addressed that
issue as well.

There are multiple issues at play here:
1) If `git merge` is invoked with staged changes, it should abort
without doing any merging, and the user's working tree and index
should be the same as before merge was invoked.
2) Merge strategies are responsible for enforcing the index == HEAD
requirement. (See 9822175d2b ("Ensure index matches head before
invoking merge machinery, round N", 2019-08-17) for some history
around this.)
3) Merge strategies can bail saying they are not an appropriate
handler for the merge in question (possibly allowing other
strategies to be used instead).
4) Merge strategies can make changes to the index and working tree,
and have no expectation to clean up after themselves, *even* if
they bail out and say they are not an appropriate handler for
the merge in question. (The `octopus` merge strategy does this,
for example.)
5) Because of (3) and (4), builtin/merge.c stashes state before
trying merge strategies and restores it afterward.
Unfortunately, if users had staged changes before calling `git merge`,
builtin/merge.c could do the following:
* stash the changes, in order to clean up after the strategies
* try all the merge strategies in turn, each of which report they
cannot function due to the index not matching HEAD
* restore the changes via "git stash apply"
But that last step would have the net effect of unstaging the user's
changes. Fix this by adding the "--index" option to "git stash apply".
While at it, also squelch the stash apply output; we already report
"Rewinding the tree to pristine..." and don't need a detailed `git
status` report afterwards. Also while at it, switch to using strvec
so folks don't have to count the arguments to ensure we avoided an
off-by-one error, and so it's easier to add additional arguments to
the command.

builtin/merge is setup to allow multiple strategies to be specified,
and it will find the "best" result and use it. This is defeated if
some of the merge strategies abort early when they cannot handle the
merge. Fix the logic that calls recursive and ort to not do such an
early abort, but instead return "2" or "unhandled" so that the next
strategy can try to handle the merge.
Coming up with a testcase for this is somewhat difficult, since
recursive and ort both handle nearly any two-headed merge (there is
a separate code path that checks for non-two-headed merges and
already returns "2" for them). So use a somewhat synthetic testcase
of having the index not match HEAD before the merge starts, since all
merge strategies will abort for that.

As noted in the last commit and the links therein (especially commit
9822175d2b ("Ensure index matches head before invoking merge machinery,
round N", 2019-08-17), we have had a very long history of problems with
failing to enforce the requirement that index matches HEAD when starting
a merge.
The "trivial merge" logic in builtin/merge.c is yet another such case
we previously missed. Add a check for it to ensure it aborts if the
index does not match HEAD, and add a testcase where this fix is needed.
Note that the fix here would also incidentally be an alternative fix
for the testcase added in the last patch, but the fix in the last patch
is still needed when multiple merge strategies are in use, so tweak the
testcase from the previous commit so that it continues to exercise the
codepath added in the last commit.

As noted in commit 9822175d2b ("Ensure index matches head before
invoking merge machinery, round N", 2019-08-17), we have had a very
long history of problems with failing to enforce the requirement that
index matches HEAD when starting a merge. One of the commits
referenced in the long tale of issues arising from lax enforcement of
this requirement was commit 55f39cf755 ("merge: fix misleading
pre-merge check documentation", 2018-06-30), which tried to document
the requirement and noted there were some exceptions. As mentioned in
that commit message, the `resolve` strategy was the one strategy that
did not have an explicit index matching HEAD check, and the reason it
didn't was that I wasn't able to discover any cases where the
implementation would fail to catch the problem and abort, and didn't
want to introduce unnecessary performance overhead of adding another
check.
Well, today I discovered a testcase where the implementation does not
catch the problem and so an explicit check is needed. Add a testcase
that previously would have failed, and update git-merge-resolve.sh to
have an explicit check. Note that the code is copied from 3ec62ad9ff
("merge-octopus: abort if index does not match HEAD", 2016-04-09), so
that we reuse the same message and avoid making translators need to
translate some new message.

When the index does not match HEAD, the merge strategies are responsible
to detect that condition and abort. The merge-ort-wrappers had code to
implement this and meant to copy the error message from merge-recursive
but deviated in two ways, both due to the message in merge-recursive
being processed by another function that made additional changes:
* It added an implicit "error: " prefix
* It added an implicit trailing newline
We can get these things by making use of the error() function.

When callers are using `cat-file` via one of the stdin-driven `--batch`
modes, all input is newline-delimited. This presents a problem when
callers wish to ask about, e.g. tree-entries that have a newline
character present in their filename.
To support this niche scenario, introduce a new `-z` mode to the
`--batch`, `--batch-check`, and `--batch-command` suite of options that
instructs `cat-file` to treat its input as NUL-delimited, allowing the
individual commands themselves to have newlines present.
The refactoring here is slightly unfortunate, since we turn loops like:
while (strbuf_getline(&buf, stdin) != EOF)
into:
while (1) {
int ret;
if (opt->nul_terminated)
ret = strbuf_getline_nul(&input, stdin);
else
ret = strbuf_getline(&input, stdin);
if (ret == EOF)
break;
}
It's tempting to think that we could use `strbuf_getwholeline()` and
specify either `\n` or `\0` as the terminating character. But for input
on platforms that include a CR character preceeding the LF, this
wouldn't quite be the same, since `strbuf_getline(...)` will trim any
trailing CR, while `strbuf_getwholeline(&buf, stdin, '\n')` will not.
In the future, we could clean this up further by introducing a variant
of `strbuf_getwholeline()` that addresses the aforementioned gap, but
that approach felt too heavy-handed for this pair of uses.
Some tests are added in t1006 to ensure that `cat-file` produces the
same output in `--batch`, `--batch-check`, and `--batch-command` modes
with and without the new `-z` option.

A future commit will want to ensure that various `--batch`-related
options produce the same output whether their input is newline
terminated, or NUL terminated (and a to-be-implemented `-z` option
exists).
To prepare for this, extract the given input(s) into separate variables
to that their LF characters can easily be converted into NUL bytes when
testing the new `-z` mode.
This is consistent with other tests in t1006 (which these days is no
longer a shining example of our CodingGuidelines).

If there is no index file, e.g., because the repository has just been
created, we return zero early (unless `must_exist` makes us die
instead.)
This early return means we do not set up `istate->repo`. With
`core.untrackedCache=true`, the recent e6a653554b ("untracked-cache:
support '--untracked-files=all' if configured", 2022-03-31) will
eventually pass down `istate->repo` as a null pointer to
`repo_config_get_string()`, causing a segmentation fault.
If we do hit this early return, set up `istate->repo` similar to when we
actually read the index.

The error handling code path is meant to be triggered when the loop does
not exit early via "break". This fails, as the boolean variable "found",
which is used to track whether the loop was exited early, is initialized
incorrectly.
It would be possible to fix this issue by correcting the initialization,
but Python supports a for:-else: control flow construct for this exact
use case (executing code if a loop does not exit early), so it is more
idiomatic to remove the tracking variable entirely.
In addition, the error message no longer refers to a variable that does
not exist.

Perforce silently replaces LF with CR LF for "utf16" files if the client
is a native Windows client. Since git's autocrlf logic does not undo
this transformation for UTF-16 encoded files, git-p4 replaces CR LF with
LF during the sync if the file type "utf16" is detected and the Perforce
client platform indicates that this conversion is performed.
Windows only runs on little-endian architectures, therefore the encoding
of the byte stream received from the Perforce client is UTF-16-LE and
the relevant byte sequence is 0D 00 0A 00.

To test this output, we need to be very careful to format the expected
error to drop the leading tab characters. Also, we need to be aware that
the verbose output from 'git rebase' is writing progress lines which
don't use traditional newlines but clear the line after every progress
item is complete. When opening the error file in an editor, these lines
are visible, but when looking at the diff in a terminal those lines
disappear because of the characters that delete the previous characters.
Use 'sed' to clear those progress lines and clear the tabs so we can get
an exact match on our expected output.

An interactive rebase provides opportunities for the user to edit the
todo list. The --update-refs option initializes the list with some
'update-ref <ref>' steps, but the user could add these manually.
Further, the user could add or remove these steps during pauses in the
interactive rebase.
Add a new method, todo_list_filter_update_refs(), that scans a todo_list
and compares it to the stored update-refs file. There are two actions
that can happen at this point:
1. If a '<ref>/<before>/<after>' triple in the update-refs file does not
have a matching 'update-ref <ref>' command in the todo-list _and_ the
<after> value is the null OID, then remove that triple. Here, the
user removed the 'update-ref <ref>' command before it was executed,
since if it was executed then the <after> value would store the
commit at that position.
2. If a 'update-ref <ref>' command in the todo-list does not have a
matching '<ref>/<before>/<after>' triple in the update-refs file,
then insert a new one. Store the <before> value to be the current
OID pointed at by <ref>. This is handled inside of the
init_update_ref_record() helper method.
We can test that this works by rewriting the todo-list several times in
the course of a rebase. Check that each ref is locked or unlocked for
updates after each todo-list update. We can also verify that the ref
update fails if a concurrent process updates one of the refs after the
rebase process records the "locked" ref location.
To help these tests, add a new 'set_replace_editor' helper that will
replace the todo-list with an exact file.

The previous change introduced the 'git rebase --update-refs' option
which added 'update-ref <ref>' commands to the todo list of an
interactive rebase.
Teach Git to record the HEAD position when reaching these 'update-ref'
commands. The ref/before/after triple is stored in the
$GIT_DIR/rebase-merge/update-refs file. A previous change parsed this
file to avoid having other processes updating the refs in that file
while the rebase is in progress.
Not only do we update the file when the sequencer reaches these
'update-ref' commands, we then update the refs themselves at the end of
the rebase sequence. If the rebase is aborted before this final step,
then the refs are not updated. The 'before' value is used to ensure that
we do not accidentally obliterate a ref that was updated concurrently
(say, by an older version of Git or a third-party tool).
Now that the 'git rebase --update-refs' command is implemented to write
to the update-refs file, we can remove the fake construction of the
update-refs file from a test in t2407-worktree-heads.sh.

When working on a large feature, it can be helpful to break that feature
into multiple smaller parts that become reviewed in sequence. During
development or during review, a change to one part of the feature could
affect multiple of these parts. An interactive rebase can help adjust
the multi-part "story" of the branch.
However, if there are branches tracking the different parts of the
feature, then rebasing the entire list of commits can create commits not
reachable from those "sub branches". It can take a manual step to update
those branches.
Add a new --update-refs option to 'git rebase -i' that adds 'update-ref
<ref>' steps to the todo file whenever a commit that is being rebased is
decorated with that <ref>. At the very end, the rebase process updates
all of the listed refs to the values stored during the rebase operation.
Be sure to iterate after any squashing or fixups are placed. Update the
branch only after those squashes and fixups are complete. This allows a
--fixup commit at the tip of the feature to apply correctly to the sub
branch, even if it is fixing up the most-recent commit in that part.
This change update the documentation and builtin to accept the
--update-refs option as well as updating the todo file with the
'update-ref' commands. Tests are added to ensure that these todo
commands are added in the correct locations.
This change does _not_ include the actual behavior of tracking the
updated refs and writing the new ref values at the end of the rebase
process. That is deferred to a later change.

The 'merge' command description for the todo list documentation in an
interactive rebase has multiple lines. The lines other than the first
one start with dots ('.') while the similar multi-line documentation for
'fixup' does not. This description only appears in the comment text of
the todo file during an interactive rebase.
The 'merge' command was documented when interactive rebase was first
ported to C in 145e05ac44b (rebase -i: rewrite append_todo_help() in C,
2018-08-10). These dots might have been carried over from the previous
shell implementation.
The 'fixup' command was documented more recently in 9e3cebd97cb (rebase
-i: add fixup [-C | -c] command, 2021-01-29).
Looking at the output in an editor, my personal opinion is that the dots
are unnecessary and noisy. Remove them now before adding more commands
with multi-line documentation.

The branch_checked_out() helper helps commands like 'git branch' and
'git fetch' from overwriting refs that are currently checked out in
other worktrees.
A future update to 'git rebase' will introduce a new '--update-refs'
option which will update the local refs that point to commits that are
being rebased. To avoid collisions as the rebase completes, we want to
make the future data store for these refs to be considered by
branch_checked_out().
The data store is a plaintext file inside the 'rebase-merge' directory
for that worktree. The file lists refnames followed by two OIDs, each on
separate lines. The OIDs will be used to store the original values of
the refs and the to-be-written values as the rebase progresses, but can
be ignored at the moment.
Create a new sequencer_get_update_refs_state() method that parses this
file and populates a struct string_list with the ref-OID pairs. We can
then use this list to add to the current_checked_out_branches strmap
used by branch_checked_out().
To properly navigate to the rebase directory for a given worktree,
extract the static strbuf_worktree_gitdir() method to a public API
method.
We can test that this works without having Git write this file by
artificially creating one in our test script, at least until 'git rebase
--update-refs' is implemented and we can use it directly.

The tests in t2407 that verify the branch_checked_out() helper in the
case of bisects and rebases were added by 9347303db89 (branch: check for
bisects and rebases, 2022-06-08). However, that commit failed to check
for rebases that are using the 'apply' backend.
Add a test that checks the apply backend. The implementation was already
correct here, but it is good to have regression tests before modifying
the implementation further.

The tests added by d2ba271aad0 (branch: check for bisects and rebases,
2022-06-14) modified hidden state to verify the branch_checked_out()
helper. While this indeed checks that the method implementation is _as
designed_, it doesn't show that it is _correct_. Specifically, if 'git
bisect' or 'git rebase' change their back-end for preserving refs, then
these tests do not demonstrate that drift as a bug in
branch_checked_out().
Modify the tests in t2407 to actually rely on a paused bisect or rebase.
This requires adding the !SANITIZE_LEAK prereq for tests using those
builtins. The logic is still tested for leaks in the final test which
does set up that back-end directly for an error state that should not be
possible using Git commands.

The word "whitelist" has cultural implications that are not inclusive.
Thankfully, it is not difficult to reword and avoid its use.
The GIT_ALLOW_PROTOCOL environment variable was referred to as a
"whitelist", but the word "allow" is already part of the variable.
Replace "whitelist" with "allow_list" in these cases to demonstrate that
we are processing a list of allowed protocols.

Focus on changes in the test scripts, since most of the changes are in
comments and test names. The renamed test_allow_var helper is only used
once inside the widely-used test_proto helper.

The documentation for GIT_ALLOW_PROTOCOL has a sentence that adds no
value, since it repeats the meaning from the previous sentence (twice!).
The word "whitelist" has cultural implications that are not inclusive,
which brought attention to this sentence.

The documentation and error messages for git-cvsserver include some
references to a "whitelist" that is not otherwise included in the
documentation. When different parts of the documentation do not use
common language, this can lead to confusion as to how things are meant
to operate.
Further, the word "whitelist" has cultural implications that make its
use non-inclusive. Thankfully, we can remove it while increasing
clarity.
Update Documentation/git-cvsserver.txt in a similar way to the previous
change to Documentation/git-daemon.txt. The optional '<directory>...'
list can specify a list of allowed directories. We refer to that list
directly inside of the documentation for the GIT_CVSSERVER_ROOT
environment variable.
While modifying this documentation, update the environment variables to
use a list format. We use the modern way of tabbing the description of
each variable in this section. We do _not_ update the description of
'<directory>...' to use tabs this way since the rest of the items in the
OPTIONS list do not use this modern formatting.
A single error message in the actual git-cvsserver.perl code refers to
the whitelist during argument parsing. Instead, refer to the directory
list that has been clarified in the documentation.
