After resolving a conflicting patch, a user may wish to sign off the
patch to declare that the patch has been modified. As such, the user
will expect that running "git am --signoff --continue" will append the
signoff to the commit message.
However, the --signoff option is only taken into account during the
mail-parsing stage. If the --signoff option is set, then the signoff
will be appended to the commit message. Since the mail-parsing stage
comes before the patch application stage, the --signoff option, if
provided on the command-line when resuming, will have no effect at all.
We cannot move the append_signoff() call to the patch application stage
as the applypatch-msg hook and interactive mode, which run before patch
application, may expect the signoff to be there.
Fix this by taking note if the user explictly set the --signoff option
on the command-line, and append the signoff to the commit message when
resuming if so.

When resuming, git-am mistakenly ignores command-line options.
For instance, when a patch fails to apply with "git am patch",
subsequently running "git am --3way" would not cause git-am to fall
back on attempting a threeway merge. This occurs because by default
the --3way option is saved as "false", and the saved am options are
loaded after the command-line options are parsed, thus overwriting
the command-line options when resuming.
Fix this by moving the am_load() function call before parse_options(),
so that command-line options will override the saved am options.
The purpose of supporting this use case is to enable users to "wiggle"
that one conflicting patch. As such, it is expected that the
command-line options do not affect subsequent applied patches. Implement
this by calling am_load() once we apply the conflicting patch
successfully.

When resuming, git-am detects if we are trying to feed it patches or not
by checking if stdin is a TTY.
However, the test library redirects stdin to /dev/null. This makes it
difficult, for instance, to test the behavior of "git am -3" when
resuming, as git-am will think we are trying to feed it patches and
error out.
Support this use case by extending test-terminal.perl to create a
pseudo-tty for the child process' standard input as well.
Note that due to the way the code is structured, the child's stdin
pseudo-tty will be closed when we finish reading from our stdin. This
means that in the common case, where our stdin is attached to /dev/null,
the child's stdin pseudo-tty will be closed immediately. Some operations
like isatty(), which git-am uses, require the file descriptor to be
open, and hence if the success of the command depends on such functions,
test_terminal's stdin should be redirected to a source with large amount
of data to ensure that the child's stdin is not closed, e.g.
test_terminal git am --3way </dev/zero

The add_to_alternates_file function blindly uses
hold_lock_file_for_append to copy the existing contents, and
then adds the new line to it. This has two minor problems:
1. We might add duplicate entries, which are ugly and
inefficient.
2. We do not check that the file ends with a newline, in
which case we would bogusly append to the final line.
This is quite unlikely in practice, though, as we call
this function only from git-clone, so presumably we are
the only writers of the file (and we always add a
newline).
Instead of using hold_lock_file_for_append, let's copy the
file line by line, which ensures all records are properly
terminated. If we see an extra line, we can simply abort the
update (there is no point in even copying the rest, as we
know that it would be identical to the original).
As a bonus, we also get rid of some calls to the
static-buffer mkpath and git_path functions.

The early part of this test is rather old, and does not
follow our usual style guidelines. In particular:
- the tests liberally chdir, and expect out-of-test "cd"
commands to return them to a sane state
- test commands aren't indented at all
- there are a lot of minor formatting nits, like the
opening quote of the test block on the wrong line,
spaces after ">", etc
This patch fixes the style issues, and uses a few helper
functions, along with subshells and "git -C", to avoid
changing the cwd of the main script.

If the URI contains a port number and the URI's path component is
empty we fail to guess a sensible directory name. E.g. cloning a
repository 'ssh://example.com:2222/' we guess a directory name
'2222' where we would want the hostname only, e.g. 'example.com'.
We need to take care to not drop trailing port-like numbers in
certain cases. E.g. when cloning a repository 'foo/bar:2222.git'
we want to guess the directory name '2222' instead of 'bar'.
Thus, we have to first check the stripped URI for path separators
and only strip port numbers if there are path separators present.
This heuristic breaks when cloning a repository 'bar:2222.git',
though.

The naive way of just adding '@' as a path separator would break
cloning repositories like 'foo/bar@baz.git' (which would

Instead fix this by first dropping the scheme and then greedily
scanning for an '@' sign until we find the first path separator.

Commit 7e837c6 (clone: simplify string handling in
guess_dir_name(), 2015-07-09) changed clone to use
strip_suffix instead of hand-rolled pointer manipulation.
However, strip_suffix will strip from the end of a
NUL-terminated string, and we may have already stripped some
characters (like directory separators, or "/.git"). This
leads to commands like:
git clone host:foo.git/
failing to strip the ".git".
We must instead convert our pointer arithmetic into a
computed length and feed that to strip_suffix_mem, which will
then reduce the length further for us.
It would be nicer if we could drop the pointer manipulation
entirely, and just continually strip using strip_suffix. But
that doesn't quite work for two reasons:
1. The early suffixes we're stripping are not constant; we
need to look for is_dir_sep, which could be one of
several characters.
2. Mid-way through the stripping we compute the pointer
"start", which shows us the beginning of the pathname.
Which really give us two lengths to work with: the
offset from the start of the string, and from the start
of the path. By using pointers for the early part, we
can just compute the length from "start" when we need
it.

When we run "git clone $url", clone guesses from the $url
what to name the local output directory. We don't have any
test coverage of this, so let's add some basic tests.
This reveals a few problems:
- cloning "foo.git/" does not properly remove the ".git";
this is a recent regression from 7e837c6 (clone:
simplify string handling in guess_dir_name(), 2015-07-09)
- likewise, cloning foo/.git does not seem to handle the
bare case (we should end up in foo.git, but we try to
use foo/.git on the local end), which also comes from
7e837c6.
- cloning the root is not very smart about URL parsing,
and usernames and port numbers may end up in the
directory name
All of these tests are marked as failures.

The "-x" test-script option turns on the shell's "-x"
tracing, which can help show why a particular test is
failing. Unfortunately, this can create false negatives in
some tests if they invoke a shell function with its stderr
redirected. t5512.10 is such a test, as it does:
test_must_fail git ls-remote refs*master >actual 2>&1 &&
test_cmp exp actual
The "actual" file gets the "-x" trace for the test_must_fail
function, which prevents it from matching the expected
output.
There's no way to avoid this without managing the
trace flag inside each sub-function, which isn't really a
workable solution. But unless you specifically care about
t5512.10, we can work around it by enabling tracing only for
the specific tests we want.
You can already do:
./t5512-ls-remote.sh -x --verbose-only=16
to see the trace only for a specific test. But that doesn't
_disable_ the tracing in the other tests; it just sends it
to /dev/null. However, there's no point in generating a
trace that the user won't see, so we can simply disable
tracing whenever it doesn't have a matching verbose flag.
The normal case of just "./t5512-ls-remote.sh -x" stays the
same, as "-x" already implies "--verbose" (and
"--verbose-only" overrides "--verbose", which is why this
works at all). And for our test, we need only check
$verbose, as maybe_setup_verbose will have already
set that flag based on the $verbose_only list).

Now that GIT_TEST_CHAIN_LINT is on by default, running:
./t0000-basic.sh -x --verbose-only=1
starts with:
expecting success:
find .git/objects -type f -print >should-be-empty &&
test_line_count = 0 should-be-empty
+ exit 117
error: last command exited with $?=117
+ find .git/objects -type f -print

ok 1 - .git/objects should be empty after git init in an empty repo
This is confusing, as the "exit 117" line and the error line
(which is printed in red, no less!) are not part of the test
at all, but are rather in the separate chain-lint test_eval.
Let's unset the "trace" variable when eval-ing the chain
lint check, which avoids this.

If you hide a hierarchy of refs using the transfer.hideRefs
config, there is no way to later override that config to
"unhide" it. This patch implements a "negative" hide which
causes matches to immediately be marked as unhidden, even if
another match would hide it. We take care to apply the
matches in reverse-order from how they are fed to us by the
config machinery, as that lets our usual "last one wins"
config precedence work (and entries in .git/config, for
example, will override /etc/gitconfig).
So you can now do:
$ git config --system transfer.hideRefs refs/secret
$ git config transfer.hideRefs '!refs/secret/not-so-secret'
to hide refs/secret in all repos, except for one public bit
in one specific repo. Or you can even do:
$ git clone \
-u "git -c transfer.hiderefs="!refs/foo" upload-pack" \
remote:repo.git
to clone remote:repo.git, overriding any hiding it has
configured.
There are two alternatives that were considered and
rejected:
1. A generic config mechanism for removing an item from a
list. E.g.: (e.g., "[transfer] hideRefs -= refs/foo").
This is nice because it could apply to other
multi-valued config, as well. But it is not nearly as
flexible. There is no way to say:
[transfer]
hideRefs = refs/secret
hideRefs = refs/secret/not-so-secret
Having explicit negative specifications means we can
override previous entries, even if they are not the
same literal string.
2. Adding another variable to override some parts of
hideRefs (e.g., "exposeRefs").
This solves the problem from alternative (1), but it
cannot easily obey the normal config precedence,
because it would use two separate lists. For example:
[transfer]
hideRefs = refs/secret
exposeRefs = refs/secret/not-so-secret
hideRefs = refs/secret/not-so-secret/no-really-its-secret
With two lists, we have to apply the "expose" rules
first, and only then apply the "hide" rules. But that
does not match what the above config intends.
Of course we could internally parse that to a single
list, respecting the ordering, which saves us having to
invent the new "!" syntax. But using a single name
communicates to the user that the ordering _is_
important. And "!" is well-known for negation, and
should not appear at the beginning of a ref (it is
actually valid in a ref-name, but all entries here
should be fully-qualified, starting with "refs/").
