Convert submodule subcommand 'summary' to a builtin and call it via
'git-submodule.sh'.
The shell version had to call $diff_cmd twice, once to find the modified
modules cared by the user and then again, with that list of modules
to do various operations for computing the summary of those modules.
On the other hand, the C version does not need a second call to
$diff_cmd since it reuses the module list from the first call to do the
aforementioned tasks.
In the C version, we use the combination of setting a child process'
working directory to the submodule path and then calling
'prepare_submodule_repo_env()' which also sets the 'GIT_DIR' to '.git',
so that we can be certain that those spawned processes will not access
the superproject's ODB by mistake.
A behavioural difference between the C and the shell version is that the
shell version outputs two line feeds after the 'git log' output when run
outside of the tests while the C version outputs one line feed in any
case. The reason for this is that the shell version calls log with
'--pretty=format:<fmt>' whose output is followed by two echo
calls; 'format' does not have "terminator" semantics like its 'tformat'
counterpart. So, the log output is terminated by a newline only when
invoked by the user and not when invoked from the scripts. This results
in the one & two line feed differences in the shell version.
On the other hand, the C version calls log with '--pretty=<fmt>'
which is equivalent to '--pretty:tformat:<fmt>' which is then
followed by a 'printf("\n")'. Due to its "terminator" semantics the
log output is always terminated by newline and hence one line feed in
any case.
Also, when we try to pass an option-like argument after a non-option
argument, for instance:
git submodule summary HEAD --foo-bar
(or)
git submodule summary HEAD --cached
That argument would be treated like a path to the submodule for which
the user is requesting a summary. So, the option ends up having no
effect. Though, passing '--quiet' is an exception to this:
git submodule summary HEAD --quiet
While 'summary' doesn't support '--quiet', we don't get an output for
the above command as '--quiet' is treated as a path which means we get
an output only if a submodule whose path is '--quiet' exists.
The error message in case of computing a summary for non-existent
submodules in the C version is different from that of the shell version.
Since the new error message is not marked for translation, change the
'test_i18ngrep' in t7421.4 to 'grep'.

test_description='Summary support for submodules, adding them using git submodule add
|
|
|
|
This test script tries to verify the sanity of summary subcommand of git submodule
|
|
while making sure to add submodules using `git submodule add` instead of
|
|
`git add` as done in t7401.
