a6d7eb2c7a pull: optionally rebase submodules (remote submodule changes only)
Teach pull to optionally update submodules when '--recurse-submodules'
is provided.  This will teach pull to run 'submodule update --rebase'
when the '--recurse-submodules' and '--rebase' flags are given under
specific circumstances.

On a rebase workflow:
=====================

1. Both sides change the submodule
 ------------------------------
Let's assume the following history in a submodule:

  H---I---J---K---L local branch
       \
        M---N---O---P remote branch

and the following in the superproject (recorded submodule in parens):

  A(H)---B(I)---F(K)---G(L)  local branch
          \
           C(N)---D(N)---E(P) remote branch

In an ideal world this would rebase the submodule and rewrite
the submodule pointers that the superproject points at such that
the superproject looks like

  A(H)---B(I)              F(K')---G(L')  rebased branch
           \                /
           C(N)---D(N)---E(P) remote branch

and the submodule as:

        J---K---L (old dangeling tip)
       /
  H---I               J'---K'---L' rebased branch
       \             /
        M---N---O---P remote branch

And if a conflict arises in the submodule the superproject rebase
would stop at that commit at which the submodule conflict occurs.

Currently a "pull --rebase" in the superproject produces
a merge conflict as the submodule pointer changes are
conflicting and cannot be resolved.

2. Local submodule changes only
 -----------------------
Assuming histories as above, except that the remote branch
would not contain submodule changes, then a result as

  A(H)---B(I)               F(K)---G(L)  rebased branch
           \                /
           C(I)---D(I)---E(I) remote branch

is desire-able. This is what currently happens in rebase.

If the recursive flag is given, the ideal git would
produce a superproject as:

  A(H)---B(I)              F(K')---G(L')  rebased branch (incl. sub rebase!)
           \                /
           C(I)---D(I)---E(I) remote branch

and the submodule as:

        J---K---L (old dangeling tip)
       /
  H---I               J'---K'---L' locally rebased branch
       \             /
        M---N---O---P advanced branch

This patch doesn't address this issue, however
a test is added that this fails up front.

3. Remote submodule changes only
 ----------------------
Assuming histories as in (1) except that the local superproject branch
would not have touched the submodule the rebase already works out in the
superproject with no conflicts:

  A(H)---B(I)               F(P)---G(P)  rebased branch (no sub changes)
           \                 /
           C(N)---D(N)---E(P) remote branch

The recurse flag as presented in this patch would additionally
update the submodule as:

  H---I              J'---K'---L' rebased branch
       \            /
        M---N---O---P remote branch

As neither J, K, L nor J', K', L' are referred to from the superproject,
no rewriting of the superproject commits is required.

Conclusion for 'pull --rebase --recursive'
 -----------------------------------------
If there are no local superproject changes it is sufficient to call
"submodule update --rebase" as this produces the desired results. In case
of conflicts, the behavior is the same as in 'submodule update --recursive'
which is assumed to be sane.

This patch implements (3) only.

On a merge workflow:
====================

We'll start off with the same underlying DAG as in (1) in the rebase
workflow. So in an ideal world a 'pull --merge --recursive' would
produce this:

  H---I---J---K---L----X
       \              /
        M---N---O---P

with X as the new merge-commit in the submodule and the superproject
as:

  A(H)---B(I)---F(K)---G(L)---Y(X)
          \                  /
           C(N)---D(N)---E(P)

However modifying the submodules on the fly is not supported in git-merge
such that Y(X) is not easy to produce in a single patch. In fact git-merge
doesn't know about submodules at all.

However when at least one side does not contain commits touching the
submodule at all, then we do not need to perform the merge for the
submodule but a fast-forward can be done via checking out either L or P
in the submodule.  This strategy is implemented in 68d03e4a6e (Implement
automatic fast-forward merge for submodules, 2010-07-07) already, so
to align with the rebase behavior we need to also update the worktree
of the submodule.

4ddb1354e8 status: contextually notify user about an initial commit
The existing message, "Initial commit", makes sense for the commit template
notifying users that it's their initial commit, but is confusing when
merely checking the status of a fresh repository (or orphan branch)
without having any commits yet.

Change the output of "status" to say "No commits yet" when "git
status" is run on a fresh repo (or orphan branch), while retaining the
current "Initial commit" message displayed in the template that's
displayed in the editor when the initial commit is being authored.

Correspondingly change the output of "short status" to "No commits yet
on " when "git status -sb" is run on a fresh repo (or orphan branch).

A few alternatives considered were,

 * Waiting for initial commit
 * Your current branch does not have any commits
 * Current branch waiting for initial commit

The most succint one among the alternatives was chosen.

[with help on tests from Ævar]

d85d7ecb80 add--interactive: quote commentChar regex
Since c9d961647 (i18n: add--interactive: mark
edit_hunk_manually message for translation, 2016-12-14),
when the user asks to edit a hunk manually, we respect
core.commentChar in generating the edit instructions.
However, when we then strip out comment lines, we use a
simple regex like:

  /^$commentChar/

If your chosen comment character is a regex metacharacter,
then that will behave in a confusing manner ("$", for
instance, would only eliminate blank lines, not actual
comment lines).

We can fix that by telling perl not to respect
metacharacters.

look like paths) and later ones are the other way around.  A
pathspec with "magic" (e.g. ":/p/a/t/h" that matches p/a/t/h from
the top-level of the working tree, no matter what subdirectory you
are working from) are conservatively judged as "not a path", which
required disambiguation more often.  The command line parser
learned to say "it's a pathspec" a bit more often when the syntax
looks like so.

    b9c8e7f2fb prefix_ref_iterator: don't trim too much, 2017-05-22

It makes more sense (and agrees better with the documentation of
`--bisect`) for the callers to receive the full reference names. So

* Add a new function, `for_each_fullref_in_submodule()`, to the refs
  API. This plugs a gap in the existing functionality, analogous to
  `for_each_fullref_in()` but accepting a `submodule` argument.

* Change `for_each_bad_bisect_ref()` to call the new function rather
  than `for_each_ref_in_submodule()`.

* Add a test.

6eced3ec5e date: use localtime() for "-local" time formats
When we convert seconds-since-epochs timestamps into a
broken-down "struct tm", we do so by adjusting the timestamp
according to the known offset and then using gmtime() to
break down the result. This means that the resulting struct
"knows" that it's in GMT, even though the time it represents
is adjusted for a different zone. The fields where it stores
this data are not portably accessible, so we have no way to
override them to tell them the real zone info.

For the most part, this works. Our date-formatting routines
don't pay attention to these inaccessible fields, and use
the same tz info we provided for adjustment. The one
exception is when we call strftime(), whose %Z format
reveals this hidden timezone data.

We solved that by always showing the empty string for %Z.
This is allowed by POSIX, but not very helpful to the user.
We can't make this work in the general case, as there's no
portable function for setting an arbitrary timezone (and
anyway, we don't have the zone name for the author zones,
only their offsets).

But for the special case of the "-local" formats, we can
just skip the adjustment and use localtime() instead of
gmtime(). This makes --date=format-local:%Z work correctly,
showing the local timezone instead of an empty string.

The new test checks the result for "UTC", our default
test-lib value for $TZ. Using something like EST5 might be
more interesting, but the actual zone string is
system-dependent (for instance, on my system it expands to
just EST). Hopefully "UTC" is vanilla enough that every
system treats it the same.

22280d7ee7 t0006: check --date=format zone offsets
We already test that "%z" and "%Z" show the right thing, but
we don't actually check that the time we display is the
correct one. Let's add two new tests:

  1. Test that "format:" shows the time in the author's
     timezone, just like the other time formats.

  2. Test that "format-local:" shows time in the local
     timezone. We don't want to use our normal UTC for this,
     because its offset is zero (so the result would be
     "correct" even if the code forgot to apply the offset
     or applied it in the wrong direction).

     We'll use the EST5 zone, which is already used
     elsewhere in the script (and so is assumed to be
     available everywhere).

c3fbf81a85 strbuf: let strbuf_addftime handle %z and %Z itself
There is no portable way to pass timezone information to strftime.  Add
parameters for timezone offset and name to strbuf_addftime and let it
handle the timezone-related format specifiers %z and %Z internally.

Callers can opt out for %Z by passing NULL as timezone name.  %z is
always handled internally -- this helps on Windows, where strftime would
expand it to a timezone name (same as %Z), in violation of POSIX.
Modifiers are not handled, e.g. %Ez is still passed to strftime.

Use an empty string as timezone name in show_date (the only current
caller) for now because we only have the timezone offset in non-local
mode.  POSIX allows %Z to resolve to an empty string in case of missing
information.

a9bcf6586d alias: use the early config machinery to expand aliases
Instead of discovering the .git/ directory, reading the config and then
trying to painstakingly reset all the global state if we did not find a
matching alias, let's use the early config machinery instead.

It may look like unnecessary work to discover the .git/ directory in the
early config machinery and then call setup_git_directory_gently() in the
case of a shell alias, repeating the very same discovery *again*.
However, we have to do this as the early config machinery takes pains
*not* to touch any global state, while shell aliases expect a possibly
changed working directory and at least the GIT_PREFIX and GIT_DIR
variables to be set.

This change also fixes a known issue where Git tried to read the pager
config from an incorrect path in a subdirectory of a Git worktree if an
alias expanded to a shell command.

3f9c5dfb71 t7006: demonstrate a problem with aliases in subdirectories
When expanding aliases, the git_dir is set during the alias expansion
(by virtue of running setup_git_directory_gently()).

This git_dir may be relative to the current working directory, and
indeed often is simply ".git/".

When the alias expands to a shell command, we restore the original
working directory, though, yet we do not reset git_dir.

As a consequence, subsequent read_early_config() runs will mistake the
git_dir to be populated properly and not find the correct config.

Demonstrate this problem by adding a test case.

We are about to change the way aliases are expanded, to use the early

This machinery reports errors in a slightly different manner than the

e2e1425107 config: report correct line number upon error
When get_value() parses a key/value pair, it is possible that the line
number is decreased (because the \n has been consumed already) before the
key/value pair is passed to the callback function, to allow for the
correct line to be attributed in case of an error.

However, when git_parse_source() asks get_value() to parse the key/value
pair, the error reporting is performed *after* get_value() returns.

Which means that we have to be careful not to increase the line number
in get_value() after the callback function returned an error.

17f2f88c9c t: move "git add submodule" into test blocks
Some submodule tests do some setup outside of a test_expect
block. This is bad because we won't actually check the
outcome of those commands. But it's doubly so because "git
add submodule" now produces a warning to stderr, which is
not suppressed by the test scripts in non-verbose mode.

This patch does the minimal to fix the annoying warnings.
All three of these scripts could use more cleanup of related
setup.

532139940c add: warn when adding an embedded repository
It's an easy mistake to add a repository inside another
repository, like:

  git clone $url
  git add .

The resulting entry is a gitlink, but there's no matching
.gitmodules entry. Trying to use "submodule init" (or clone
with --recursive) doesn't do anything useful. Prior to
v2.13, such an entry caused git-submodule to barf entirely.
In v2.13, the entry is considered "inactive" and quietly
ignored. Either way, no clone of your repository can do
anything useful with the gitlink without the user manually
adding the submodule config.

In most cases, the user probably meant to either add a real
submodule, or they forgot to put the embedded repository in
their .gitignore file.

Let's issue a warning when we see this case. There are a few
things to note:

  - the warning will go in the git-add porcelain; anybody
    wanting to do low-level manipulation of the index is
    welcome to create whatever funny states they want.

  - we detect the case by looking for a newly added gitlink;
    updates via "git add submodule" are perfectly reasonable,
    and this avoids us having to investigate .gitmodules
    entirely

  - there's a command-line option to suppress the warning.
    This is needed for git-submodule itself (which adds the
    entry before adding any submodule config), but also
    provides a mechanism for other scripts doing
    submodule-like things.

We could make this a hard error instead of a warning.
However, we do add lots of sub-repos in our test suite. It's
not _wrong_ to do so. It just creates a state where users
may be surprised. Pointing them in the right direction with
a gentle hint is probably the best option.

There is a config knob that can disable the (long) hint. But
I intentionally omitted a config knob to disable the warning
entirely. Whether the warning is sensible or not is
generally about context, not about the user's preferences.
If there's a tool or workflow that adds gitlinks without
matching .gitmodules, it should probably be taught about the
new command-line option, rather than blanket-disabling the
warning.
