Introduce commit.gpgsign configuration variable to force every
commit to be GPG signed. The variable cannot be overriden from the
command line of some of the commands that create commits except for
"git commit" and "git commit-tree", but I am not convinced that it
is a good idea to sprinkle support for --no-gpg-sign everywhere,
which in turn means that this configuration variable may not be
such a good idea.

- when commit.gpgsign is true, "git commit --no-gpg-sign" creates
unsigned commits
- when commit.gpgsign is true, "git rebase -f" creates signed commits

When QUICK is set (i.e. with --quiet) we try to do as little work as
possible, stopping after seeing the first change. stat-dirty is
considered a "change" but it may turn out not, if no actual content is
changed. The actual content test is performed too late in the process
and the shortcut may be taken prematurely, leading to incorrect return
code.
Assume we do "git diff --quiet". If we have a stat-dirty file "a" and
a really dirty file "b". We break the loop in run_diff_files() and
stop after "a" because we have got a "change". Later in
diffcore_skip_stat_unmatch() we find out "a" is actually not
changed. But there's nothing else in the diff queue, we incorrectly
declare "no change", ignoring the fact that "b" is changed.
This also happens to "git diff --quiet HEAD" when it hits
diff_can_quit_early() in oneway_diff().
This patch does the content test earlier in order to keep going if "a"
is unchanged. The test result is cached so that when
diffcore_skip_stat_unmatch() is done in the end, we spend no cycles on
re-testing "a".

where "correct paths" stands for paths that are different to all

Up until now, we were testing combined diff only on one file, or on
several files which were all different (t4038-diff-combined.sh).
As recent thinko in "simplify intersect_paths() further" showed, and
also, since we are going to rework code for finding paths different to
all parents, lets write at least basic tests.

This patch activates the DO_MATCH_DIRECTORY code in m_p_i(), which
makes "git diff HEAD submodule/" and "git diff HEAD submodule" produce
the same output. Previously only the version without trailing slash
returns the difference (if any).
That's the effect of new ce_path_match(). dir_path_match() is not
executed by the new tests. And it should not introduce regressions.
Previously if path "dir/" is passed in with pathspec "dir/", they
obviously match. With new dir_path_match(), the path becomes
_directory_ "dir" vs pathspec "dir/", which is not executed by the old
code path in m_p_i(). The new code path is executed and produces the
same result.
The other case is pathspec "dir" and path "dir/" is now turned to
"dir" (with DO_MATCH_DIRECTORY). Still the same result before or after
the patch.
So why change? Because of the next patch about clean.c.

The previous code only checked out branches in cmd_add. This commit
moves the branch-checkout logic into module_clone, where it can be
shared by cmd_add and cmd_update. I also update the initial checkout
command to use 'reset' to preserve branches setup during module_clone.
With this change, folks cloning submodules for the first time via:
$ git submodule update ...
will get a local branch instead of a detached HEAD, unless they are
using the default checkout-mode updates. This is a change from the
previous situation where cmd_update always used checkout-mode logic
(regardless of the requested update mode) for updates that triggered
an initial clone, which always resulted in a detached HEAD.
This commit does not change the logic for updates after the initial
clone, which will continue to create detached HEADs for checkout-mode
updates, and integrate remote work with the local HEAD (detached or
not) in other modes.
The motivation for the change is that developers doing local work
inside the submodule are likely to select a non-checkout-mode for
updates so their local work is integrated with upstream work.
Developers who are not doing local submodule work stick with
checkout-mode updates so any apparently local work is blown away
during updates. For example, if upstream rolls back the remote branch
or gitlinked commit to an earlier version, the checkout-mode developer
wants their old submodule checkout to be rolled back as well, instead
of getting a no-op merge/rebase with the rolled-back reference.
By using the update mode to distinguish submodule developers from
black-box submodule consumers, we can setup local branches for the
developers who will want local branches, and stick with detached HEADs
for the developers that don't care.
Testing
=======
In t7406, just-cloned checkouts now update to the gitlinked hash with
'reset', to preserve the local branch for situations where we're not
on a detached HEAD.
I also added explicit tests to t7406 for HEAD attachement after
cloning updates, showing that it depends on their update mode:
* Checkout-mode updates get detached HEADs
* Everyone else gets a local branch, matching the configured
submodule.<name>.branch and defaulting to master.
The 'initial-setup' tag makes it easy to reset the superproject to a
known state, as several earlier tests commit to submodules and commit
the changed gitlinks to the superproject, but don't push the new
submodule commits to the upstream subprojects. This makes it
impossible to checkout the current super master, because it references
submodule commits that don't exist in the upstream subprojects. For a
specific example, see the tests that currently generate the
'two_new_submodule_commits' commits.
Documentation
=============
I updated the docs to describe the 'submodule update' modes in detail.
The old documentation did not distinguish between cloning and
non-cloning updates and lacked clarity on which operations would lead
to detached HEADs, and which would not. The new documentation
addresses these issues while updating the docs to reflect the changes
introduced by this commit's explicit local branch creation in
module_clone.
I also add '--checkout' to the usage summary and group the update-mode
options into a single set.

Sometimes when working with a large repository it can be useful to try
out a merge and only check out conflicting files to disk (for example as
a speed optimization on a server). Until v1.7.7-rc1~28^2~20
(merge-recursive: When we detect we can skip an update, actually skip
it, 2011-08-11), it was possible to do so with the following idiom:
# Prepare a temporary index and empty work tree.
GIT_INDEX_FILE="$PWD/tmp-$$-index" &&
export GIT_INDEX_FILE &&
GIT_WORK_TREE="$PWD/tmp-$$-work" &&
export GIT_WORK_TREE &&
mkdir "$GIT_WORK_TREE" &&
# Convince the index that our side is on disk.
git read-tree -i -m $ours &&
git update-index --ignore-missing --refresh &&
# Merge their side into our side.
bases=$(git merge-base --all $ours $theirs) &&
git merge-recursive $bases -- $ours $theirs &&
tree=$(git write-tree)
Nowadays, that still works and the exit status is the same, but
merge-recursive produces a diagnostic if "our" side renamed a file:
error: addinfo_cache failed for path 'dst'
Add a test to document this regression.

In smart http, upload-pack adds new shallow lines at the beginning of
each rpc response. Only shallow lines from the first rpc call are
useful. After that they are thrown away. It's designed this way
because upload-pack is stateless and has no idea when its shallow
lines are helpful or not.
So after refs are negotiated with multi_ack_detailed and the server
thinks it learned enough, it sends "ACK obj-id ready", terminates the
rpc call and waits for the final rpc round. The client sends "done".
The server sends another response, which also has shallow lines at
the beginning, and the last "ACK obj-id" line.
When no-done is active, the last round is cut out, the server sends
"ACK obj-id ready" and "ACK obj-id" in the same rpc
response. fetch-pack is updated to recognize this and not send
"done". However it still tries to consume shallow lines, which are
never sent.
Update the code, make sure to skip consuming shallow lines when
no-done is enabled.

We set the default apache port for each of the httpd tests
to the 4-digit test number of the test script. We want these
to remain unique so that the tests do not conflict with each
other when run in parallel.
Instead of doing it manually in each test script, let's just
set it from the test name at run time. This is simpler, and
is one less thing to be updated when test scripts are
renamed (e.g., when being re-rolled or when conflicting
after being merged with another topic).
Incidentally, this fixes a case where t5537 and t5538 used
the same port number (5537), and could conflict with each
other when run in parallel.

The prefix_path_gently() function currently applies real_path to
everything if given an absolute path, dereferencing symlinks both
outside and inside the work tree.
This causes most high-level functions to misbehave when acting on
symlinks given via absolute paths. For example
$ git add /dir/repo/symlink
attempts to add the target of the symlink rather than the symlink
itself, which is usually not what the user intends to do.
In order to manipulate symlinks in the work tree using absolute paths,
symlinks should only be dereferenced outside the work tree.
Modify the prefix_path_gently() to first normalize the path in order to
make sure path levels are separated by '/', then pass the result to
'abspath_part_inside_repo' to find the part inside the work tree
(without dereferencing any symlinks inside the work tree).
For absolute paths, prefix_path_gently() did not, nor does now do, any
actual prefixing, hence the result from abspath_part_in_repo() is
returned as-is.
Fixes t0060-82 and t3004-5.

One edge-case that isn't currently checked in the tests is the beginning
of the path matching the work tree, despite the target not actually
being the work tree, for example:
path = /dir/repoa
work_tree = /dir/repo
should fail since the path is outside the repo. However, if /dir/repoa
is in fact a symlink that points to /dir/repo, it should instead
succeed.

t7501.9 tries to check that "git commit" will fail when the
index is unchanged. It relies on previous tests not to have
modified the index. When it was originally written, this was
always the case. However, commit c65dc35 (t7501: test the
right kind of breakage, 2012-03-30) changed earlier tests (4
and 5) to leave a modification in the index.
We never noticed, however, because t7501.7, between the two,
clears the index state as a side effect. However, that test
depends on the PERL prerequisite, and so it does not always
run. Therefore if NO_PERL is set, we do not run the
intervening test, the index is left unclean, and t7501.9
fails.
We could fix this by moving t7501.9 up in the script.
However, this patch instead leaves it in place and adds a
"git reset" before the commit. This makes the test more
explicit about its preconditions, and will future-proof it
against any other changes in the test state.
