ead74601c6 tests: don't assume a .git/info for .git/info/sparse-checkout
Change those tests that assumed that a .git/info directory would be
created for them when writing .git/info/sparse-checkout to explicitly
create the directory by setting "TEST_CREATE_REPO_NO_TEMPLATE=1"
before sourcing test-lib.sh, and using the "--template=" argument to
"git clone".

f172556b89 cherry-pick: use better advice message
"git cherry-pick", upon seeing a conflict, says:

hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'

as if running "git commit" to conclude the resolution of
this single step were the end of the story.  This stems from
the fact that the command originally was to pick a single
commit and not a range of commits, and the message was
written back then and has not been adjusted.

When picking a range of commits and the command stops with a
conflict in the middle of the range, however, after
resolving the conflict and (optionally) recording the result
with "git commit", the user has to run "git cherry-pick
--continue" to have the rest of the range dealt with,
"--skip" to drop the current commit, or "--abort" to discard
the series.

Suggest use of "git cherry-pick --continue/--skip/--abort"
so that the message also covers the case where a range of
commits are being picked.

Similarly, this optimization can be applied to git revert,
suggest use of "git revert --continue/--skip/--abort" so
that the message also covers the case where a range of
commits are being reverted.

It is worth mentioning that now we use advice() to print
the content of GIT_CHERRY_PICK_HELP in print_advice(), each
line of output will start with "hint: ".

1108cea7f8 tests: remove most uses of test_i18ncmp
As a follow-up to d162b25f95 (tests: remove support for
GIT_TEST_GETTEXT_POISON, 2021-01-20) remove most uses of test_i18ncmp
via a simple s/test_i18ncmp/test_cmp/g search-replacement.

I'm leaving t6300-for-each-ref.sh out due to a conflict with in-flight
changes between "master" and "seen", as well as the prerequisite
itself due to other changes between "master" and "next/seen" which add
new test_i18ncmp uses.

334afbc76f tests: mark tests relying on the current default for init.defaultBranch
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 -- \
		t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
		t/t1011-read-tree-sparse-checkout.sh \
		t/t1305-config-include.sh t/t1309-early-config.sh \
		t/t1402-check-ref-format.sh t/t1450-fsck.sh \
		t/t2024-checkout-dwim.sh \
		t/t2106-update-index-assume-unchanged.sh \
		t/t3040-subprojects-basic.sh t/t3301-notes.sh \
		t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \
		t/t3436-rebase-more-options.sh \
		t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \
		t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \
		t/t5511-refspec.sh t/t5526-fetch-submodules.sh \
		t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \

		t/t7508-status.sh t/t7606-merge-custom.sh \
		t/t9302-fast-import-unpack-limit.sh

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\
	' t/t980[0167]*.sh t/t9811*.sh

7d056deace sequencer: avoid garbled merge machinery messages due to commit labels
sequencer's get_message() exists to provide good labels on conflict
hunks; see commits
  d68565402a ("revert: clarify label on conflict hunks", 2010-03-20)
  bf975d379d ("cherry-pick, revert: add a label for ancestor", 2010-03-20)
  043a4492b3 ("sequencer: factor code out of revert builtin", 2012-01-11).
for background on this function.  These labels are of the form
  <commitID>... <commit summary>
or
  parent of <commitID>... <commit summary>
These labels are then passed as branch names to the merge machinery.
However, these labels, as formatted, often also serve to confuse.  For
example, if we have a rename involved in a content merge, then it
results in text such as the following:

    <<<<<<<< HEAD:foo.c
      int j;
    ========
      int counter;
    >>>>>>>> b01dface... Removed unnecessary stuff:bar.c

Or in various conflict messages, it can make it very difficult to read:

    CONFLICT (rename/delete): foo.c deleted in b01dface... Removed
    unnecessary stuff and renamed in HEAD.  Version HEAD of foo.c left
    in tree.

    CONFLICT (file location): dir1/foo.c added in b01dface... Removed
    unnecessary stuff inside a directory that was renamed in HEAD,
    suggesting it should perhaps be moved to dir2/foo.c.

Make a minor change to remove the ellipses and add parentheses around
the commit summary; this makes all three examples much easier to read:

    <<<<<<<< HEAD:foo.c
      int j;
    ========
      int counter;
    >>>>>>>> b01dface (Removed unnecessary stuff):bar.c

    CONFLICT (rename/delete): foo.c deleted in b01dface (Removed
    unnecessary stuff) and renamed in HEAD.  Version HEAD of foo.c left
    in tree.

    CONFLICT (file location): dir1/foo.c added in b01dface (Removed
    unnecessary stuff) inside a directory that was renamed in HEAD,
    suggesting it should perhaps be moved to dir2/foo.c.

c76b84a121 t: don't spuriously close and reopen quotes
In the test scripts, the recommended style is, e.g.:

    test_expect_success 'name' '
        do-something somehow &&
        do-some-more testing
    '

When using this style, any single quote in the multi-line test section
is actually closing the lone single quotes that surround it.

It can be a non-issue in practice:

    test_expect_success 'sed a little' '
        sed -e 's/hi/lo/' in >out # "ok": no whitespace in s/hi/lo/
    '

Or it can be a bug in the test, e.g., because variable interpolation
happens before the test even begins executing:

    v=abc

    test_expect_success 'variable interpolation' '
        v=def &&
        echo '"$v"' # abc
    '

Change several such in-test single quotes to use double quotes instead
or, in a few cases, drop them altogether. These were identified using
some crude grepping. We're not fixing any test bugs here, but we're
hopefully making these tests slightly easier to grok and to maintain.

There are legitimate use cases for closing a quote and opening a new
one, e.g., both '\'' and '"'"' can be used to produce a literal single
quote. I'm not touching any of those here.

In t9401, tuck the redirecting ">" to the filename while we're touching
those lines.

b07d9bfd17 commit/reset: try to clean up sequencer state
When cherry-picking or reverting a sequence of commits and if the final
pick/revert has conflicts and the user uses `git commit` to commit the
conflict resolution and does not run `git cherry-pick --continue` then
the sequencer state is left behind. This can cause problems later. In my
case I cherry-picked a sequence of commits the last one of which I
committed with `git commit` after resolving some conflicts, then a while
later, on a different branch I aborted a revert which rewound my HEAD to
the end of the cherry-pick sequence on the previous branch. Avoid this
potential problem by removing the sequencer state if we're committing or
resetting the final pick in a sequence.

2b75fb601c merge-recursive: preserve skip_worktree bit when necessary
merge-recursive takes any files marked as unmerged by unpack_trees,
tries to figure out whether they can be resolved (e.g. using renames
or a file-level merge), and then if they can be it will delete the old
cache entries and writes new ones.  This means that any ce_flags for
those cache entries are essentially cleared when merging.

Unfortunately, if a file was marked as skip_worktree and it needs a
file-level merge but the merge results in the same version of the file
that was found in HEAD, we skip updating the worktree (because the
file was unchanged) but clear the skip_worktree bit (because of the
delete-cache-entry-and-write-new-one).  This makes git treat the file
as having a local change in the working copy, namely a delete, when it
should appear as unchanged despite not being present.  Avoid this
problem by copying the skip_worktree flag in this case.

261f315beb merge & sequencer: turn "Conflicts:" hint into a comment
Just like other hints such as "Changes to be committed" we show in
the editor to remind the committer what paths were involved in the
resulting commit to help improving their log message, this section
is merely a reminder.

Traditionally, it was not made into comments primarily because it
has to be generated outside the wt-status infrastructure, and also
because it was meant as a bit stronger reminder than the others
(i.e. explaining how you resolved conflicts is much more important
than mentioning what you did to every paths involved in the commit).

But that still does not make this hint a part of the log message
proper, and not showing it as a comment is inviting mistakes.

Note that we still notice "Conflicts:" followed by list of indented
pathnames as an old-style cruft and insert a new Signed-off-by:
before it.  This is so that "commit --amend -s" adds the new S-o-b
at the right place when used on an older commit.

ed727b192b cherry-pick: No advice to commit if --no-commit
When cherry-pick fails it offers a helpful hint about how to
proceed.  The hint tells the user how to do the cleanup
needed by the conflicted cherry-pick and finish the job after
conflict resolution.  In case of cherry-pick --no-commit, the
hint goes too far. It tells the user to finish up with
'git commit'.  That is not what this git-cherry-pick was
trying to do in the first place.

Restrict the hint in case of --no-commit to avoid giving this
extra advice.

Also, add a test verifying the reduced hint for the --no-commit
version of cherry-pick.

82433cdf4d revert: write REVERT_HEAD pseudoref during conflicted revert
When conflicts are encountered while reverting a commit, it can be
handy to have the name of that commit easily available.  For example,
to produce a copy of the patch to refer to while resolving conflicts:

	$ git revert 2eceb2a8
	error: could not revert 2eceb2a8... awesome, buggy feature
	$ git show -R REVERT_HEAD >the-patch
	$ edit $(git diff --name-only)

Set a REVERT_HEAD pseudoref when "git revert" does not make a commit,
for cases like this.  This also makes it possible for scripts to
distinguish between a revert that encountered conflicts and other
sources of an unmerged index.

After successfully committing, resetting with "git reset", or moving
to another commit with "git checkout" or "git reset", the pseudoref is
no longer useful, so remove it.

9fa8aecdeb revert.c: defer writing CHERRY_PICK_HEAD till it is safe to do so
do_pick_commit() writes out CHERRY_PICK_HEAD before invoking merge (either
via do_recursive_merge() or try_merge_command()) on the assumption that if
the merge fails it is due to conflict. However, if the tree is dirty, the
merge may not even start, aborting before do_pick_commit() can remove
CHERRY_PICK_HEAD.

Instead, defer writing CHERRY_PICK_HEAD till after merge has returned.
At this point we know the merge has either succeeded or failed due
to conflict. In either case, we want CHERRY_PICK_HEAD to be written
so that it may be picked up by the subsequent invocation of commit.

Note that do_recursive_merge() aborts if the merge cannot start, while
try_merge_command() returns a non-zero value other than 1.

cb6aeb22ac i18n: git-revert split up "could not revert/apply" message
Split up the "could not %s %s... %s" message into "could not revert
%s... %s" and "could not apply %s... %s". This makes it easier for
translators to understand the message.

37f7a85793 Teach commit about CHERRY_PICK_HEAD
Previously the user was advised to use commit -c CHERRY_PICK_HEAD after
a conflicting cherry-pick. While this would preserve the original
commit's authorship, it would sadly discard cherry-pick's carefully
crafted MERGE_MSG (which contains the list of conflicts as well as the
original commit-id in the case of cherry-pick -x).

On the other hand, if a bare 'commit' were performed, it would preserve
the MERGE_MSG while resetting the authorship.

In other words, there was no way to simultaneously take the authorship
from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.

This change fixes that situation. A bare 'commit' will now take the
authorship from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
If the user wishes to reset authorship, that must now be done explicitly
via --reset-author.

A side-benefit of passing commit authorship along this way is that we
can eliminate redundant authorship parsing code from revert.c.

(Also removed an unused include from revert.c)

d7e5c0cbfb Introduce CHERRY_PICK_HEAD
When a cherry-pick conflicts git advises:

 $ git commit -c <original commit id>

to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:

  $ git commit -c CHERRY_PICK_HEAD

A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

2161da1039 t3507: introduce pristine-detach helper
All the tests in t3507 (cherry-pick with conflicts) begin with the
same checkout + read-tree + clean incantation to ensure a predictable
starting point.  Factor out a function for that so the interesting
part of the tests is easier to read.

The "update-index --refresh" and "diff-index --exit-code HEAD" are not
necessary as the point of this testsuite is not about testing
"read-tree --reset".

314eeb6e48 cherry-pick/revert: Use advise() for hints
When cherry-pick fails after picking a large series of commits, it can
be hard to pick out the error message and advice.  Prefix the advice
with “hint: ” to help.

Before:

    error: could not apply 7ab78c9... foo
      After resolving the conflicts,
    mark the corrected paths with 'git add <paths>' or 'git rm <paths>'
    and commit the result with:

            git commit -c 7ab78c9a7898b87127365478431289cb98f8d98f

After:

    error: could not apply 7ab78c9... foo
    hint: after resolving the conflicts, mark the corrected paths
    hint: with 'git add <paths>' or 'git rm <paths>'
    hint: and commit the result with 'git commit -c 7ab78c9'

bf975d379d cherry-pick, revert: add a label for ancestor
When writing conflict hunks in ‘diff3 -m’ format, also add a label to
the common ancestor.  Especially in a cherry-pick, it is not immediately
obvious without such a label what the common ancestor represents.

git rerere does not have trouble parsing the new output and its preimage
ids are unchanged since it includes its own code for recreating conflict
hunks.  No other code in git parses conflict hunks.

d68565402a revert: clarify label on conflict hunks
When reverting a commit, the commit being merged is not the commit
to revert itself but its parent.  Add “parent of” to the conflict
hunk label to make this more clear.

The conflict hunk labels are all pieces of a single string written in
the new get_message() function.  Avoid some complication by using
mempcpy to advance a pointer as the result is written.

Also free the corresponding temporary buffer (it was leaked before).
This is not important because it is a small one-time allocation.  It
would become a memory leak if unnoticed when libifying revert.

This patch uses calls to strlen() instead of integer constants in some
places.  GCC will compute the length at compile time; I am not sure
about other compilers, but this is not performance-critical anyway.
