Test fixes.
* sg/test-must-be-empty:
tests: use 'test_must_be_empty' instead of 'test_cmp <empty> <out>'
tests: use 'test_must_be_empty' instead of 'test_cmp /dev/null <out>'
tests: use 'test_must_be_empty' instead of 'test ! -s'
tests: use 'test_must_be_empty' instead of '! test -s'
|

Using 'test_must_be_empty' is shorter and more idiomatic than
>empty &&
test_cmp empty out
as it saves the creation of an empty file. Furthermore, sometimes the
expected empty file doesn't have such a descriptive name like 'empty',
and its creation is far away from the place where it's finally used
for comparison (e.g. in 't7600-merge.sh', where two expected empty
files are created in the 'setup' test, but are used only about 500
lines later).
These cases were found by instrumenting 'test_cmp' to error out the
test script when it's used to compare empty files, and then converted
manually.
Note that even after this patch there still remain a lot of cases
where we use 'test_cmp' to check empty files:
- Sometimes the expected output is not hard-coded in the test, but
'test_cmp' is used to ensure that two similar git commands produce
the same output, and that output happens to be empty, e.g. the
test 'submodule update --merge - ignores --merge for new
submodules' in 't7406-submodule-update.sh'.
- Repetitive common tasks, including preparing the expected results
and running 'test_cmp', are often extracted into a helper
function, and some of this helper's callsites expect no output.
- For the same reason as above, the whole 'test_expect_success'
block is within a helper function, e.g. in 't3070-wildmatch.sh'.
- Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update
(-p)' in 't9400-git-cvsserver-server.sh'.

"git mergetool" (without any pathspec on the command line) that is
not run from the top-level of the working tree no longer works in
Git v2.11, failing to get the list of unmerged paths from the output
of "git rerere remaining". This regression was introduced by
57937f70a0 ("mergetool: honor diff.orderFile", 2016-10-07).
This is because the pathnames output by the 'git rerere remaining'
command are relative to the top-level directory but the 'git diff
--name-only' command expects its pathname arguments to be relative
to the current working directory. To make everything consistent,
cd_to_toplevel before running 'git diff --name-only' and adjust any
relative pathnames.

Test code clean-up.
* ak/lazy-prereq-mktemp:
t7610: clean up foo.XXXXXX tmpdir
|
|
The lazy prereq for MKTEMP uses "mktemp -t" to see if
mergetool's internal mktemp call will be able to run. But
unlike the call inside mergetool, we do not ever bother to
clean up the result, and the /tmp of git developers will
slowly fill up with "foo.XXXXXX" directories as they run the
test suite over and over. Let's clean up the directory
after we've verified its creation.
Note that we don't use test_when_finished here, and instead
just make rmdir part of the &&-chain. We should only remove
something that we're confident we just created. A failure in
the middle of the chain either means there's nothing to
clean up, or we are very confused and should err on the side
of caution.

test_config uses test_when_finished to reset the configuration after the

Currently using "git rm" on a submodule removes the submodule's work tree
from that of the superproject and the gitlink from the index. But the
submodule's section in .gitmodules is left untouched, which is a leftover
of the now removed submodule and might irritate users (as opposed to the
setting in .git/config, this must stay as a reminder that the user showed
interest in this submodule so it will be repopulated later when an older
commit is checked out).
Let "git rm" help the user by not only removing the submodule from the
work tree but by also removing the "submodule.<submodule name>" section
from the .gitmodules file and stage both. This doesn't happen when the
"--cached" option is used, as it would modify the work tree. This also
silently does nothing when no .gitmodules file is found and only issues a
warning when it doesn't have a section for this submodule. This is because
the user might just use plain gitlinks without the .gitmodules file or has
already removed the section by hand before issuing the "git rm" command
(in which case the warning reminds him that rm would have done that for
him). Only when .gitmodules is found and contains merge conflicts the rm
command will fail and tell the user to resolve the conflict before trying
again.
Also extend the man page to inform the user about this new feature. While
at it promote the submodule sub-section to a chapter as it made not much
sense under "REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM".
In t7610 three uses of "git rm submod" had to be replaced with "git rm
--cached submod" because that test expects .gitmodules and the work tree
to stay untouched. Also in t7400 the tests for the remaining settings in
the .gitmodules file had to be changed to assert that these settings are
missing.

* da/mergetool-custom:
mergetool--lib: Allow custom commands to override built-ins
|
|
Allow users to override the default commands provided by the
mergetools/* scriptlets.
Users occasionally run into problems where they expect to be
able to override the built-in tool names. The documentation
does not explicitly mention that built-ins cannot be overridden,
so it's easy to assume that it should work.
Lift this restriction so that built-in tools are handled the
same way as user-configured tools. Add tests to guarantee this
behavior.
A nice benefit of this change is that it protects users from
having future versions of git trump their custom configuration
with a new built-in tool.

"stash apply" directly calls a backend merge function which does not

Add a test to make sure that a conflicted "stash apply" invokes
rerere to record the conflicts and resolve the the files it can
(the current code doesn't, so the test is marked as failing).
Without correct state recorded for rerere, mergetool may be
confused, causing it to think no files have conflicts even though
they do. This condition is not verified by this test since a
subsequent commit will change the behavior to enable rerere for
stash conflicts.
Also, the next test expected us to finish up with a reset, which is
impossible to do if we fail (as we must) and it's an unreasonable
expectation anyway. Begin the next test with a reset of its own
instead.

Some merge tools cannot cope when $LOCAL, $BASE, or $REMOTE are missing.
$BASE can be missing when two branches independently add the same
filename.
Provide an empty file to make these tools happy.
When a delete/modify conflict occurs, $LOCAL and $REMOTE can also be
missing. We have special case code to handle such case so this change
may not affect that codepath, but try to be consistent and create an

Mergetool now treats its path arguments as a pathspec (like other git
subcommands), restricting action to the given files and directories.
Files matching the pathspec are filtered so mergetool only acts on
unmerged paths; previously it would assume each path argument was in an
unresolved state, and get confused when it couldn't check out their
other stages.
Running "git mergetool subdir" will prompt to resolve all conflicted
blobs under subdir.

When the index has conflicted submodules, mergetool used to mildly
clobber the module, renaming it to mymodule.BACKUP.nnnn, then failing to
copy it non-recursively.
Recognize submodules and offer a resolution instead:
Submodule merge conflict for 'Shared':
{local}: submodule commit ad9f12e3e6205381bf2163a793d1e596a9e211d0
{remote}: submodule commit f5893fb70ec5646efcd9aa643c5136753ac89253
Use (l)ocal or (r)emote, or (a)bort?
Selecting a commit will stage it, but not update the submodule (as git
does had there been no conflict). Type changes are also supported,
should the path be a submodule on one side, and a file, symlink,
directory, or deleted on the other.

Since bb0a484 (mergetool: Skip autoresolved paths, 2010-08-17),
mergetool uses different ways of figuring out the list of files with
merge conflicts depending on whether rerere is active. If rerere is
active, mergetool will use 'git rerere status' to list the files with
remaining conflicts. However, the output from that command does not
list conflicts of types that rerere does not handle, such as
modify/remove conflicts.
Another problem with solely relying on the output from 'git rerere
status' is that, for new conflicts that are not yet known to rerere,
the output from the command will list the files even after adding them
to the index. This means that if the conflicts in some files have been
resolved and 'git mergetool' is run again, it will ask the user
something like the following for each of those files.
file1: file does not need merging
Continue merging other unresolved paths (y/n) ?
Solve both of these problems by replacing the call to 'git rerere
status' with a call to the new 'git rerere remaining' that was
introduced in the previous commit.

When mergetool is run without path limiters it loops
over each entry in 'git ls-files -u'. This includes
autoresolved paths.
Teach mergetool to only merge files listed in 'rerere status'
when rerere is enabled.
There are some subtle but harmless changes in behavior.
We now call cd_to_toplevel when no paths are given.
We do this because 'rerere status' paths are always relative
to the root. This is beneficial for the non-rerere use as
well in that mergetool now runs against all unmerged files
regardless of the current directory.
This also slightly tweaks the output when run without paths
to be more readable.
The old output:
Merging the files: foo
bar
baz
The new output:
Merging:
foo
bar
