diff: teach diff to display submodule difference with an inline diff Teach git-diff and friends a new format for displaying the difference of a submodule. The new format is an inline diff of the contents of the submodule between the commit range of the update. This allows the user to see the actual code change caused by a submodule update. Add tests for the new format and option. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

tests: use 'test_must_be_empty' instead of 'test_cmp <empty> <out>' 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'.

tests: use 'test_must_be_empty' instead of '! test -s' Using 'test_must_be_empty' is preferable to '! test -s', because it gives a helpful error message if the given file is unexpectedly not empty, while the latter remains completely silent. Furthermore, it also catches cases when the given file unexpectedly does not exist at all. This patch was basically created by: sed -i -e 's/! test -s/test_must_be_empty/' t[0-9]*.sh with the following notable exceptions: - The '! test -s' check in '.gitmodules ignore=dirty suppresses submodules with untracked content' in 't7508-status.sh' is left as-is, because it's bogus and, therefore, it's subject of a dedicated patch. - The '! test -s' checks in 't9131-git-svn-empty-symlink.sh' and 't9135-git-svn-moved-branch-empty-file.sh' are immediately preceeded by a 'test -f' to ensure that the files exist in the first place. 'test_must_be_empty' ensures that as well, so those 'test -f' commands are removed as well. Signed-off-by: SZEDER Gábor <szeder.dev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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.

diff: submodule inline diff to initialize env array. David reported: > When I try to run `git diff --submodule=diff` in a submodule which has > it's own submodules that have changes I get the error: fatal: bad > object. This happens, because we do not properly initialize the environment in which the diff is run in the submodule. That means we inherit the environment from the main process, which sets environment variables. (Apparently we do set environment variables which we do not set when not in a submodules, i.e. the .git directory is linked) This commit, just like fd47ae6a5b (diff: teach diff to display submodule difference with an inline diff, 2016-08-31) introduces bad test code (i.e. hard coded hash values), which will be cleanup up in a later patch.
