a463aefa35 test-terminal: set output terminals to raw mode
Not setting them to raw mode causes funny things to happen, such as
\n -> \r\n translation:

  0000000: 666f 6f0d 0a                             foo..

(Notice the added 0d.)

To avoid this, set the (pseudo)terminal to raw mode.  Note that the
IO::Pty docs recommend doing it on both master and slave.

f032d66ddb request-pull: do not emit "tag" before the tagname
The whole point of the recent update to allow "git pull $url $tagname" is
so that the integrator does not have to store the (signed) tag that is
used to convey authenticity to be recorded in the resulting merge in the
local repository's tag namespace.  Asking for a merge be made with "git
pull $url tag $tagname" defeats it.

Note that the request can become ambiguous if the requestor has a branch
with the same name as the tag, but that is not a new problem limited to
pulling. I wouldn't mind if somebody wants to add disambiguation to the
find_matching_ref logic in the script as a separate patch, though.

02f7914734 remote-curl: don't pass back fake refs
When receive-pack advertises its list of refs, it generally hides the
capabilities information after a NUL at the end of the first ref.

However, when we have an empty repository, there are no refs, and
therefore receive-pack writes a fake ref "capabilities^{}" with the
capabilities afterwards.

On the client side, git reads the result with get_remote_heads(). We pick
the capabilities from the end of the line, and then call check_ref() to
make sure the ref name is valid. We see that it isn't, and don't bother
adding it to our list of refs.

However, the call to check_ref() is enabled by passing the REF_NORMAL flag
to get_remote_heads. For the regular git transport, we pass REF_NORMAL in
get_refs_via_connect() if we are doing a push (since only receive-pack
uses this fake ref).  But in remote-curl, we never use this flag, and we
accept the fake ref as a real one, passing it back from the helper to the
parent git-push.

Most of the time this bug goes unnoticed, as the fake ref won't match our
refspecs. However, if "--mirror" is used, then we see it as remote cruft
to be pruned, and try to pass along a deletion refspec for it. Of course
this refspec has bogus syntax (because of the ^{}), and the helper
complains, aborting the push.

Let's have remote-curl mirror what the builtin get_refs_via_connect() does
(at least for the case of using git protocol; we can leave the dumb
info/refs reader as it is).

This also fixes pushing with --mirror to a smart-http remote that uses
alternates. The fake ".have" refs the server gives to avoid unnecessary
network transfer has a similar bad interactions with the machinery.

bf71009e53 t3502, t3510: clarify cherry-pick -m failure
The "cherry-pick persists opts correctly" test in t3510
(cherry-pick-sequence) can cause some confusion, because the command
actually has two points of failure:

1. "-m 1" is specified on the command-line despite the base commit
   "initial" not being a merge-commit.
2. The revision range indicates that there will be a conflict that
   needs to be resolved.

Although the former error is trapped, and cherry-pick die()s with the
exit status 128, the reader may be distracted by the latter.  Fix this
by changing the revision range to something that wouldn't cause a
conflict.  Additionally, explicitly check the exit code in
"cherry-pick a non-merge with -m should fail" in t3502
(cherry-pick-merge) to reassure the reader that this failure has
nothing to do with the sequencer itself.

c6b7c7f305 t3510 (cherry-pick-sequencer): use exit status
All the tests asserting failure use 'test_must_fail', which simply
checks for a non-zero exit status, potentially hiding underlying bugs.
So, replace instances of 'test_must_fail' with 'test_expect_code' to
check the exit status explicitly, where appropriate.

6bc1a235b1 revert: make commit subjects in insn sheet optional
Change the instruction sheet format subtly so that the subject of the
commit message that follows the object name is optional.  As a result,
an instruction sheet like this is now perfectly valid:

  pick 7362160f

While at it, also fix a bug introduced by 5a5d80f4 (revert: Introduce
--continue to continue the operation, 2011-08-04) that failed to read
lines that are too long to fit on the commit-id-shaped buffer we
currently use; eliminate the need for the buffer altogether.  In
addition to literal SHA-1 hexes, you can now safely use expressions
like the following in the instruction sheet:

37576c1443 commit_tree(): refuse commit messages that contain NULs
Current implementation sees NUL as terminator. If users give a message
with NUL byte in it (e.g. editor set to save as UTF-16), the new commit
message will have NULs. However following operations (displaying or
amending a commit for example) will not keep anything after the first NUL.

Stop user right when they do this. If NUL is added by mistake, they have
their chance to fix. Otherwise, log messages will no longer be text "git
log" and friends would grok.

781f76b158 test-lib: redirect stdin of tests
We want to run tests in a predictable, sterile environment
so we can get repeatable results.  They should take as
little input as possible from the environment outside the
test script. We already sanitize environment variables, but
leave stdin untouched. This means that scripts can
accidentally be impacted by content on stdin, or whether
stdin isatty().

Furthermore, scripts reading from stdin can be annoying to
outer loops which care about their stdin offset, like:

  while read sha1; do
      make test
  done

A test which accidentally reads stdin would soak up all of
the rest of the input intended for the outer shell loop.

Let's redirect stdin from /dev/null, which solves both
of these problems. It won't detect tests accidentally
reading from stdin, but since doing so now gives a
deterministic result, we don't need to consider that an
error.

We'll also leave file descriptor 6 as a link to the original
stdin. Tests shouldn't need to look at this, but it can be
convenient for inserting interactive commands while
debugging tests (e.g., you could insert "bash <&6 >&3 2>&4"
to run interactive commands in the environment of the test
script).

0d16451943 test: errors preparing for a test are not special
This script uses the following idiom to start each test in a known
good state:

	test_expect_success 'some commands use a pager' '
		rm -f paginated.out || cleanup_fail &&
		test_terminal git log &&
		test -e paginated.out
	'

where "cleanup_fail" is a function that prints an error message and
errors out.

That is bogus on three levels:

 - Cleanup commands like "rm -f" and "test_unconfig" are designed not
   to fail, so this logic would never trip.

 - If they were to malfunction anyway, it is not useful to set apart
   cleanup commands as a special kind of failure with a special error
   message.  Whichever command fails, the next step is to investigate
   which command that was, for example by running tests with
   "prove -e 'sh -x'", and fix it.

 - Relying on left-associativity of mixed &&/|| lists makes the code
   somewhat cryptic.

The fix is simple: drop the "|| cleanup_fail" in each test and the
definition of the "cleanup_fail" function so no new callers can arise.

a4ddbc33d7 http-push: enable "proactive auth"
Before commit 986bbc08, git was proactive about asking for
http passwords. It assumed that if you had a username in
your URL, you would also want a password, and asked for it
before making any http requests.

However, this could interfere with the use of .netrc (see
986bbc08 for details). And it was also unnecessary, since
the http fetching code had learned to recognize an HTTP 401
and prompt the user then. Furthermore, the proactive prompt
could interfere with the usage of .netrc (see 986bbc08 for
details).

Unfortunately, the http push-over-DAV code never learned to
recognize HTTP 401, and so was broken by this change. This
patch does a quick fix of re-enabling the "proactive auth"
strategy only for http-push, leaving the dumb http fetch and
smart-http as-is.

0521710a8b t5540: test DAV push with authentication
We don't currently test this case at all, and instead just
test the DAV mechanism over an unauthenticated push. That
isn't very realistic, as most people will want to
authenticate pushes.

Two of the tests expect_failure as they reveal bugs:

  1. Pushing without a username in the URL fails to ask for
     credentials when we get an HTTP 401. This has always
     been the case, but it would be nice if it worked like
     smart-http.

  2. Pushing with a username fails to ask for the password
     since 986bbc0 (http: don't always prompt for password,
     2011-11-04). This is a severe regression in v1.7.8, as
     authenticated push-over-DAV is now totally unusable

1e7ba0f9ca fetch-pack: match refs exactly
When we are determining the list of refs to fetch via
fetch-pack, we have two sets of refs to compare: those on
the remote side, and a "match" list of things we want to
fetch. We iterate through the remote refs alphabetically,
seeing if each one is wanted by the "match" list.

Since def88e9 (Commit first cut at "git-fetch-pack",
2005-07-04), we have used the "path_match" function to do a
suffix match, where a remote ref is considered wanted if
any of the "match" elements is a suffix of the remote
refname.

This enables callers of fetch-pack to specify unqualified
refs and have them matched up with remote refs (e.g., ask
for "A" and get remote's "refs/heads/A"). However, if you
provide a fully qualified ref, then there are corner cases
where we provide the wrong answer. For example, given a
remote with two refs:

   refs/foo/refs/heads/master
   refs/heads/master

asking for "refs/heads/master" will first match
"refs/foo/refs/heads/master" by the suffix rule, and we will
erroneously fetch it instead of refs/heads/master.

As it turns out, all callers of fetch_pack do provide
fully-qualified refs for the match list. There are two ways
fetch_pack can get match lists:

  1. Through the transport code (i.e., via git-fetch)

  2. On the command-line of git-fetch-pack

In the first case, we will always be providing the names of
fully-qualified refs from "struct ref" objects. We will have
pre-matched those ref objects already (since we have to
handle more advanced matching, like wildcard refspecs), and
are just providing a list of the refs whose objects we need.

In the second case, users could in theory be providing
non-qualified refs on the command-line. However, the
fetch-pack documentation claims that refs should be fully
qualified (and has always done so since it was written in
2005).

Let's change this path_match call to simply check for string
equality, matching what the callers of fetch_pack are
expecting.

e9d866e32c t5500: give fully-qualified refs to fetch-pack
The fetch-pack documentation is very clear that refs given
on the command line are to be full refs:

  <refs>...::
          The remote heads to update from. This is relative to
          $GIT_DIR (e.g. "HEAD", "refs/heads/master").  When
          unspecified, update from all heads the remote side has.

and this has been the case since fetch-pack was originally documented in
8b3d9dc ([PATCH] Documentation: clone/fetch/upload., 2005-07-14).

Let's follow our own documentation to set a good example,
and to avoid breaking when this restriction is enforced in
the next patch.

861444f6d7 t: add test harness for external credential helpers
We already have tests for the internal helpers, but it's
nice to give authors of external tools an easy way to
sanity-check their helpers.

If you have written the "git-credential-foo" helper, you can
do so with:

  GIT_TEST_CREDENTIAL_HELPER=foo \
  make t0303-credential-external.sh

This assumes that your helper is capable of both storing and
retrieving credentials (some helpers may be read-only, and
they will fail these tests).

If your helper supports time-based expiration with a
configurable timeout, you can test that feature like this:

  GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
  make t0303-credential-external.sh

This is like "cache", except that we actually put the

This is not unlike using .netrc to store entries, but it's a

218b65fbf9 revert: do not remove state until sequence is finished
As v1.7.8-rc0~141^2~4 (2011-08-04) explains, git cherry-pick removes
the sequencer state just before applying the final patch.  In the
single-pick case, that was a good thing, since --abort and --continue
work fine without access to such state and removing it provides a
signal that git should not complain about the need to clobber it ("a
cherry-pick or revert is already in progress") in sequences like the
following:

	git cherry-pick foo
	git read-tree -m -u HEAD; # forget that; let's try a different one
	git cherry-pick bar

After the recent patch "allow single-pick in the middle of cherry-pick
sequence" we don't need that hack any more.  In the new regime, a
traditional "git cherry-pick <commit>" command never looks at
.git/sequencer, so we do not need to cripple "git cherry-pick
<commit>..<commit>" for it any more.

So now you can run "git cherry-pick --abort" near the end of a
multi-pick sequence and it will abort the entire sequence, instead of
misbehaving and aborting just the final commit.

Since 7e2bfd3f (revert: allow cherry-picking more than one commit,

commits to be cherry-picked or reverted using commit_argc and

Future callers as other commands are built in (am, rebase, sequencer)
may find it easier to pass rev-list options to this machinery in

093a309136 revert: allow cherry-pick --continue to commit before resuming
When "git cherry-pick ..bar" encounters conflicts, permit the operator
to use cherry-pick --continue after resolving them as a shortcut for
"git commit && git cherry-pick --continue" to record the resolution
and carry on with the rest of the sequence.

This improves the analogy with "git rebase" (in olden days --continue
was the way to preserve authorship when a rebase encountered
conflicts) and fits well with a general UI goal of making "git cmd
--continue" save humans the trouble of deciding what to do next.

Example: after encountering a conflict from running "git cherry-pick
foo bar baz":

	CONFLICT (content): Merge conflict in main.c
	error: could not apply f78a8d98c... bar!
	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'

We edit main.c to resolve the conflict, mark it acceptable with "git
add main.c", and can run "cherry-pick --continue" to resume the
sequence.

	$ git cherry-pick --continue
	[editor opens to confirm commit message]
	[master 78c8a8c98] bar!
	 1 files changed, 1 insertions(+), 1 deletions(-)
	[master 87ca8798c] baz!
	 1 files changed, 1 insertions(+), 1 deletions(-)

This is done for both codepaths to pick multiple commits and a single
commit.

e2770979fe credentials: add "cache" helper
If you access repositories over smart-http using http
authentication, then it can be annoying to have git ask you
for your password repeatedly. We cache credentials in
memory, of course, but git is composed of many small
programs. Having to input your password for each one can be
frustrating.

This patch introduces a credential helper that will cache
passwords in memory for a short period of time.

a78fbb4fb6 credential: make relevance of http path configurable
When parsing a URL into a credential struct, we carefully
record each part of the URL, including the path on the
remote host, and use the result as part of the credential
context.

This had two practical implications:

  1. Credential helpers which store a credential for later
     access are likely to use the "path" portion as part of
     the storage key. That means that a request to

       https://example.com/foo.git

     would not use the same credential that was stored in an
     earlier request for:

       https://example.com/bar.git

  2. The prompt shown to the user includes all relevant
     context, including the path.

In most cases, however, users will have a single password
per host. The behavior in (1) will be inconvenient, and the
prompt in (2) will be overly long.

This patch introduces a config option to toggle the
relevance of http paths. When turned on, we use the path as
before. When turned off, we drop the path component from the
context: helpers don't see it, and it does not appear in the
prompt.

This is nothing you couldn't do with a clever credential
helper at the start of your stack, like:

  [credential "http://"]
	helper = "!f() { grep -v ^path= ; }; f"
	helper = your_real_helper

But doing this:

  [credential]
	useHttpPath = false

is way easier and more readable. Furthermore, since most
users will want the "off" behavior, that is the new default.
Users who want it "on" can set the variable (either for all
credentials, or just for a subset using
credential.*.useHttpPath).

118250728e credential: apply helper config
The functionality for credential storage helpers is already
there; we just need to give the users a way to turn it on.
This patch provides a "credential.helper" configuration
variable which allows the user to provide one or more helper
strings.

Rather than simply matching credential.helper, we will also
compare URLs in subsection headings to the current context.
This means you can apply configuration to a subset of
credentials. For example:

  [credential "https://example.com"]
	helper = foo

would match a request for "https://example.com/foo.git", but
not one for "https://kernel.org/foo.git".

This is overkill for the "helper" variable, since users are
unlikely to want different helpers for different sites (and
since helpers run arbitrary code, they could do the matching
themselves anyway).

However, future patches will add new config variables where
this extra feature will be more useful.

148bb6a7b4 http: use credential API to get passwords
This patch converts the http code to use the new credential
API, both for http authentication as well as for getting
certificate passwords.

Most of the code change is simply variable naming (the
passwords are now contained inside the credential struct)
or deletion of obsolete code (the credential code handles
URL parsing and prompting for us).

The behavior should be the same, with one exception: the
credential code will prompt with a description based on the
credential components. Therefore, the old prompt of:

  Username for 'example.com':
  Password for 'example.com':

now looks like:

  Username for 'https://example.com/repo.git':
  Password for 'https://user@example.com/repo.git':

Note that we include more information in each line,
specifically:

  1. We now include the protocol. While more noisy, this is
     an important part of knowing what you are accessing
     (especially if you care about http vs https).

  2. We include the username in the password prompt. This is
     not a big deal when you have just been prompted for it,
     but the username may also come from the remote's URL
     (and after future patches, from configuration or
     credential helpers).  In that case, it's a nice
     reminder of the user for which you're giving the
     password.

  3. We include the path component of the URL. In many
     cases, the user won't care about this and it's simply
     noise (i.e., they'll use the same credential for a
     whole site). However, that is part of a larger
     question, which is whether path components should be
     part of credential context, both for prompting and for
     lookup by storage helpers. That issue will be addressed
     as a whole in a future patch.

Similarly, for unlocking certificates, we used to say:

  Certificate Password for 'example.com':

and we now say:

  Password for 'cert:///path/to/certificate':

Showing the path to the client certificate makes more sense,
as that is what you are unlocking, not "example.com".

abca927dbe introduce credentials API
There are a few places in git that need to get a username
and password credential from the user; the most notable one
is HTTP authentication for smart-http pushing.

Right now the only choices for providing credentials are to
put them plaintext into your ~/.netrc, or to have git prompt
you (either on the terminal or via an askpass program). The
former is not very secure, and the latter is not very
convenient.

Unfortunately, there is no "always best" solution for
password management. The details will depend on the tradeoff
you want between security and convenience, as well as how
git can integrate with other security systems (e.g., many
operating systems provide a keychain or password wallet for
single sign-on).

This patch provides an abstract notion of credentials as a
data item, and provides three basic operations:

  - fill (i.e., acquire from external storage or from the
    user)

  - approve (mark a credential as "working" for further
    storage)

  - reject (mark a credential as "not working", so it can
    be removed from storage)

These operations can be backed by external helper processes
that interact with system- or user-specific secure storage.

We could try to parse the command-line ourselves and figure

- Use test_expect_code() in preference to checking the exit status of

- Guard commands that prepare test input for individual tests in the
  same test_expect_success, so that their scope is clearer and errors
  at that stage can be caught.

- Use <<-\EOF in preference to <<EOF to save readers the trouble of

- Include "setup" in the titles of test assertions that prepare for
  later ones to make it more obvious which tests can be skipped.

create a bogus branch "--help", so run it under 'test_might_fail'.

1af524eba1 t7501 (commit): modernize style
Put the opening quote starting each test on the same line as the
test_expect_* invocation.  While at it:

- guard commands that prepare test input for individual tests in
  the same test_expect_success, so their scope is clearer and
  errors at that stage can be caught;
- use the compare_diff_patch helper function when comparing patches;
- use single-quotes in preference to double-quotes and <<\EOF in
  preference to <<EOF, to save readers the trouble of looking for
  variable interpolations;
- lift the setting of the $author variable used throughout the
  test script to the top of the test script;
- include "setup" in the titles of test assertions that prepare for
  later ones to make it more obvious which tests can be skipped;
- use test_must_fail instead of "if ...; then:; else false; fi",
  for clarity and to catch segfaults when they happen;
- break up some pipelines into separate commands that read and write
  to ordinary files, and test the exit status at each stage;
- chain commands with &&.  Breaks in a test assertion's && chain can
  potentially hide failures from earlier commands in the chain;
- combine two initial tests that do not make as much sense alone.

67a612c4e5 test: remove a porcelain test that hard-codes commit names
The rev-list output in this test depends on the details of test_tick's
dummy dates and the choice of hash function.  Worse, it depends on the
order and nature of commits made in the earlier tests, so adding new
tests or rearranging existing ones breaks it.

It would be nice to check that "git commit" and commit-tree name
objects consistently and that commit objects' text is as documented,
but this particular test checks everything at once and hence is not a
robust test for that.  Remove it.

11c8a74a64 commit: write cache-tree data when writing index anyway
In prepare_index(), we refresh the index, and then write it to disk if
this changed the index data.  After running hooks we re-read the index
and compute the root tree sha1 with the cache-tree machinery.

This gives us a mostly free opportunity to write up-to-date cache-tree
data: we can compute it in prepare_index() immediately before writing
the index to disk.

If we do this, we were going to write the index anyway, and the later
cache-tree update has no further work to do.  If we don't do it, we
don't do any extra work, though we still don't have have cache-tree
data after the commit.

The only case that suffers badly is when the pre-commit hook changes
many trees in the index.  I'm writing this off as highly unusual.

4eb0346fb8 Test the current state of the cache-tree optimization
The cache-tree optimization originally helped speed up write-tree
operation.  However, many commands no longer properly maintain -- or
use an opportunity to cheaply generate -- the cache-tree data.  In
particular, this affects commit, checkout and reset.  The notable
examples that *do* write cache-tree data are read-tree and write-tree.

This sadly means most people no longer benefit from the optimization,
as they would not normally use the plumbing commands.

Document the current state of affairs in a test file, in preparation
for improvements in the area.

5e9637c629 i18n: add infrastructure for translating Git with gettext
Change the skeleton implementation of i18n in Git to one that can show
localized strings to users for our C, Shell and Perl programs using
either GNU libintl or the Solaris gettext implementation.

This new internationalization support is enabled by default. If
gettext isn't available, or if Git is compiled with
NO_GETTEXT=YesPlease, Git falls back on its current behavior of
showing interface messages in English. When using the autoconf script
we'll auto-detect if the gettext libraries are installed and act
appropriately.

This change is somewhat large because as well as adding a C, Shell and
Perl i18n interface we're adding a lot of tests for them, and for
those tests to work we need a skeleton PO file to actually test
translations. A minimal Icelandic translation is included for this
purpose. Icelandic includes multi-byte characters which makes it easy
to test various edge cases, and it's a language I happen to
understand.

The rest of the commit message goes into detail about various
sub-parts of this commit.

= Installation

Gettext .mo files will be installed and looked for in the standard
$(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to
override that, but that's only intended to be used to test Git itself.

= Perl

Perl code that's to be localized should use the new Git::I18n
module. It imports a __ function into the caller's package by default.

Instead of using the high level Locale::TextDomain interface I've
opted to use the low-level (equivalent to the C interface)
Locale::Messages module, which Locale::TextDomain itself uses.

Locale::TextDomain does a lot of redundant work we don't need, and
some of it would potentially introduce bugs. It tries to set the
$TEXTDOMAIN based on package of the caller, and has its own
hardcoded paths where it'll search for messages.

I found it easier just to completely avoid it rather than try to
circumvent its behavior. In any case, this is an issue wholly
internal Git::I18N. Its guts can be changed later if that's deemed
necessary.

See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for
a further elaboration on this topic.

= Shell

Shell code that's to be localized should use the git-sh-i18n
library. It's basically just a wrapper for the system's gettext.sh.

If gettext.sh isn't available we'll fall back on gettext(1) if it's
available. The latter is available without the former on Solaris,
which has its own non-GNU gettext implementation. We also need to
emulate eval_gettext() there.

If neither are present we'll use a dumb printf(1) fall-through
wrapper.

= About libcharset.h and langinfo.h

We use libcharset to query the character set of the current locale if
it's available. I.e. we'll use it instead of nl_langinfo if
HAVE_LIBCHARSET_H is set.

The GNU gettext manual recommends using langinfo.h's
nl_langinfo(CODESET) to acquire the current character set, but on
systems that have libcharset.h's locale_charset() using the latter is
either saner, or the only option on those systems.

GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either,
but MinGW and some others need to use libcharset.h's locale_charset()
instead.

=Credits

cc64b318f2 builtin/apply.c: report error on failure to recognize input
When git apply is passed something that is not a patch, it does not produce
an error message or exit with a non-zero status if it was not actually
"applying" the patch i.e. --check or --numstat etc were supplied on the
command line.

Fix this by producing an error when apply fails to find any hunks whatsoever
while parsing the patch.

This will cause some of the output formats (--numstat, --diffstat, etc) to
produce an error when they formerly would have reported zero changes and
exited successfully.  That seems like the correct behavior though.  Failure
to recognize the input as a patch should be an error.

Plus, add a test.

The third test "apply --build-fake-ancestor in a subdirectory" has been
broken since it was introduced.  It intended to modify a tracked file named
'sub/3.t' and then produce a diff which could be git apply'ed, but the file
named 'sub/3.t' does not exist.  The file that exists in the repo is called
'sub/3'.  Since no tracked files were modified, an empty diff was produced,
and the test succeeded.

Correct this test by supplying the intended name of the tracked file,
'sub/3.t', to test_commit in the first test.

1838685780 fast-import: Fix incorrect fanout level when modifying existing notes refs
This fixes the bug uncovered by the tests added in the previous two patches.

When an existing notes ref was loaded into the fast-import machinery, the
num_notes counter associated with that ref remained == 0, even though the
true number of notes in the loaded ref was higher. This caused a fanout
level of 0 to be used, although the actual fanout of the tree could be > 0.
Manipulating the notes tree at an incorrect fanout level causes removals to
silently fail, and modifications of existing notes to instead produce an
additional note (leaving the old object in place at a different fanout level).

This patch fixes the bug by explicitly counting the number of notes in the
notes tree whenever it looks like the num_notes counter could be wrong (when
num_notes == 0). There may be false positives (i.e. triggering the counting
when the notes tree is truly empty), but in those cases, the counting should
not take long.

The previous patch exposed a bug in fast-import where _removing_ an existing

(subject to the same circumstances).

d1075414dc t9301: Fix testcase covering up a bug in fast-import's notes fanout handling
There is a bug in fast-import where the fanout levels of an existing notes
tree being loaded into the fast-import machinery is disregarded. Instead, any
tree loaded is assumed to have a fanout level of 0. If the true fanout level
is deeper, any attempt to remove a note from that tree will silently fail
(as the note will not be found at fanout level 0).

However, this bug was covered up by the way in which the t9301 testcase was
written: When generating the fast-import commands to test mass removal of
notes, we appended these commands to an already existing 'input' file which
happened to already contain the fast-import commands used in the previous
subtest to generate the very same notes tree. This would normally be harmless
(but suboptimal) as the notes created were identical to the notes already
present in the notes tree. But the act of repeating all the notes additions
caused the internal fast-import data structures to recalculate the fanout,
instead of hanging on to the initial (incorrect) fanout (that causes the bug
described above). Thus, the subsequent removal of notes in the same 'input'
file would succeed, thereby covering up the bug described above.

This patch creates a new 'input' file instead of appending to the file from
the previous subtest. Thus, we end up properly testing removal of notes that
were added by a previous fast-import command. As a side effect, the notes
removal can no longer refer to commits using the marks set by the previous
fast-import run, instead the commits names must be referenced directly.

The underlying fast-import bug is still present after this patch, but now we
have at least uncovered it. Therefore, the affected subtests are labeled as
expected failures until the underlying bug is fixed.

b15aa973b2 revert --abort: do not leave behind useless sequencer-old directory
The "git cherry-pick --abort" command currently renames the
.git/sequencer directory to .git/sequencer-old instead of removing it
on success due to an accident.  cherry-pick --abort is designed to
work in three steps:

 1) find which commit to roll back to
 2) call "git reset --merge <commit>" to move to that commit
 3) remove the .git/sequencer directory

But the careless author forgot step 3 entirely.  The only reason the
command worked anyway is that "git reset --merge <commit>" renames the
.git/sequencer directory as a secondary effect --- after moving to
<commit>, or so the logic goes, it is unlikely but possible that the
caller of git reset wants to continue the series of cherry-picks that
was in progress, so git renames the sequencer state to
.git/sequencer-old to be helpful while allowing the cherry-pick to be
resumed if the caller did not want to end the sequence after all.

By running "git cherry-pick --abort", the operator has clearly
indicated that she is not planning to continue cherry-picking.  Remove
the (renamed) .git/sequencer directory as intended all along.
