Various subcommands of the "git submodule" command exited with 0
status even though the path given by the user did not exist.
The reason behind that was that they all pipe the output of
module_list into the while loop which then does the action on the
paths specified by the commandline. Since the exit code of the
command on the upstream side of the pipe is ignored by the shell,
the status code of "ls-files --error-unmatch" nor "module_list" was
not propagated.
In case ls-files returns with an error code, we write a special
string that is not possible in non error situations, and no other
output, so that the downstream can detect the error and die with an
error code.
The error message that there is an unmatched pathspec comes through
stderr directly from ls-files. So the user still gets a hint whats going
on.

There are three ways to specify an external diff command:
GIT_EXTERNAL_DIFF in the environment, diff.external in the
config, or a "diff" gitattribute. The current order of
precedence is:
1. gitattribute
2. GIT_EXTERNAL_DIFF
3. diff.external
Usually our rule is that environment variables should take
precedence over on-disk config (i.e., option 2 should come
before option 1). However, this situation is trickier than
some, because option 1 is more specific to the individual
file than option 2 (which affects all files), so it might be
preferable. So the current behavior can be seen as
implementing "do the specific thing if we can, but fall back
to this general thing".
This is probably not what we would do if we were writing git
from scratch, but it has been this way for several years,
and is not worth changing. So let's at least document that
this is the way it's supposed to work with a test.
While we're there, let's also make sure that diff.external
(which was not previously tested at all) works by running it
through the same tests as GIT_EXTERNAL_DIFF.

Upon seeing a type-change filepair, "diff --no-ext-diff" does not
show the usual "deletion followed by addition" split patch and does
not run the external diff driver either.
This is because the logic to disable external diff was placed at a
wrong level in the callchain. run_diff_cmd() decides to show the
split patch only when external diff driver is not configured or
specified via GIT_EXTERNAL_DIFF environment, but this is done before
checking if --no-ext-diff was given. To make things worse,
run_diff_cmd() checks --no-ext-diff and disables the output for such
a filepair completely, as the callchain below it (e.g. builtin_diff)
does not want to handle typechange filepairs.

Since 69c3051 (submodules: refactor computation of relative gitdir path)
cloning a submodule recursively fails for nested submodules when a
symbolic link is part of the path to the work tree of the superproject.
This happens when module_clone() tries to find the relative paths between
the work tree and the git dir. When a symbolic link in current $PWD points
to a directory that is at a different level, then determining the number
of "../" needed to traverse to the superproject's work tree leads to a
wrong result.
As there is no portable way to say "pwd -P", use cd_to_toplevel to remove
the link from $PWD, which fixes this problem.
A test for this issue has been added to t7406.

When we do not have any pathspec, we typically disallow an
explicit "--only", because it makes no sense (your commit
would, by definition, be empty). But since 6a74642
(git-commit --amend: two fixes., 2006-04-20), we have
allowed "--amend --only" with the intent that it would amend
the commit, ignoring any contents staged in the index.
However, while that commit allowed the combination, we never
actually implemented the logic to make it work. The current
code notices that we have no pathspec and assumes we want to
do an as-is commit (i.e., the "--only" is ignored).
Instead, we must make sure to follow the partial-commit
code-path. We also need to tweak the list_paths function to
handle a NULL pathspec.

"git commit --amend" used on a commit with an empty message fails
unless -m is given, whether or not --allow-empty-message is
specified.
Allow it to proceed to the editor with an empty commit message.
Unless --allow-empty-message is in force, it will still abort later
if an empty message is saved from the editor (this check was
already necessary to prevent a non-empty commit message being edited
to an empty one).
Add a test for --amend --edit of an empty commit message which fails
without this fix, as it's a rare case that won't get frequently
tested otherwise.

Only "diff --no-index -" does. Bolting the logic into the low-level
function diff_populate_filespec() was a layering violation from day
one. Move populate_from_stdin() function out of the generic diff.c
to its only user, diff-index.c.
Also make sure "-" from the command line stays a special token "read
from the standard input", even if we later decide to sanitize the
result from prefix_filename() function in a few obvious ways,
e.g. removing unnecessary "./" prefix, duplicated slashes "//" in
the middle, etc.

A path containing a space must be quoted when used as an
argument to either the copy or rename commands (because
unlike other commands, the path is not the final thing on
the line for those commands).
Commit 6280dfdc3b (fast-export: quote paths in output,
2011-08-05) previously attempted to fix fast-export's
quoting by passing all paths through quote_c_style().
However, that function does not consider the space to be a
character which requires quoting, so let's special-case the
space inside print_path(). This will cause space-containing
paths to also be quoted in other commands where such quoting
is not strictly necessary, but it does not hurt to do so.
The test from 6280dfdc3b did not detect this because, while
it does introduce renames in the export stream, it does not
actually turn on rename detection, so they were presented as
pairs of deletions/adds. Using "-M" reveals the bug.

When running 'git diff --quiet <file1> <file2>', if file1 or file2
is outside the repository, it will exit(0) even if the files differ.
It should exit(1) when they differ.
This happens because 'diff_no_index' looks at the 'found_changes'
member from 'diff_options' to determine if changes were made. This
is the wrong thing to do, since it is only set if xdiff is actually
run and it finds a change (the diff machinery will optimize out the
xdiff call when it is not necessary) and in that case HAS_CHANGED
flag needs to be taken into account.
Use diff_result_code() that knows all these details for the correct
exit value instead.

The logic of git-show has remained largely unchanged since around
5d7eeee (git-show: grok blobs, trees and tags, too, 2006-12-14): start
a revision walker with no_walk=1, look at its pending objects and
handle them one-by-one. For commits, this means stuffing them into a
new queue all alone, and running the walker.
Then Linus's f222abd (Make 'git show' more useful, 2009-07-13) came
along and set no_walk=0 whenever the user specifies a range. Which
appears to work fine, until you actually prod it hard enough, as the
preceding commit shows: UNINTERESTING commits will be marked as such,
but not walked further to propagate the marks.
Demonstrate this with the main tests of this patch: 'showing a range
walks (Y shape)'. The Y shape of history ensures that propagating the
UNINTERESTING marks is necessary to correctly exclude the main1
commit. The only example I could find actually requires that the
negative revisions are listed later, and in this scenario a dotted
range actually works. However, it is easy to find examples in git.git
where a dotted range is wrong, e.g.
$ git show v1.7.0..v1.7.1 | grep ^commit | wc -l
1297
$ git rev-list v1.7.0..v1.7.1 | wc -l
702
While there, also test a few other things that are not covered so far:
the -N way of triggering a range (added in 5853cae, DWIM 'git show -5'
to 'git show --do-walk -5', 2010-06-01), and the interactions of tags,
commits and ranges.

verify_filename() can be called in two different contexts. Either we
just tried to interpret a string as an object name, and it fails, so
we try looking for a working tree file (i.e. we finished looking at
revs that come earlier on the command line, and the next argument
must be a pathname), or we _know_ that we are looking for a
pathname, and shouldn't even try interpreting the string as an
object name.
For example, with this change, we get:
$ git log COPYING HEAD:inexistant
fatal: HEAD:inexistant: no such path in the working tree.
Use '-- <path>...' to specify paths that do not exist locally.
$ git log HEAD:inexistant
fatal: Path 'inexistant' does not exist in 'HEAD'

diagnose_invalid_sha1_path() is meant to be called to diagnose a
misspelt <treeish>:<pathname> when <pathname> does not exist in
<treeish>. However, the code may call it if <treeish>:<pathname> is
invalid (which triggers another call with only_to_die == 1), but for
another reason. This happens when calling e.g.
git log existing-file HEAD:existing-file
because existing-file is a path and not a revision, the code
verifies that the arguments that follow to be paths. This leads to
an incorrect message like "existing-file does not exist in HEAD",
even though the path exists in HEAD.
Check that the search for <pathname> in <treeish> fails before
triggering the diagnosis.
