[PATCH v2] commit: support commit.verbose and --no-verbose

Incorporated changes from Duy Nguyen and Jeremiah Mahler.

Jeremiah, I didn't make the changes about `<<-EOF` or `test_expect_success`
because I'm guessing that keeping the local style of the code intact is more
important than using those. Do you think it makes sense to refactor the rest of
the test file (t/t7507-commit-verbose.sh) to use those? I could also change the
other `git config` calls to use `test_config`.

Duy, you were right about `-V`. Do you know of a simple way to add that
shortened flag? `OPT_BOOL('v', "verbose", ...)` gives me `-v`, `--verbose`, and
`--no-verbose`, but no `-V` as a shortened form of `--no-verbose`.

    commit: support commit.verbose and --no-verbose

    Add a new configuration variable commit.verbose to implicitly pass
    `--verbose` to `git-commit`. Add `--no-verbose` to commit to negate that
    setting.

Why is there two spaces between "diff  at"?
Needs a space between "the`comm" -> "the `comm".

Me personally, I would leave it like that for now, since that is
the style being used nearby.  We'll see what others have to say.

I certainly wouldn't convert all the other cases to use
test_expect_success.  Leave that for another patch.

I like those better with 'test_config' instead of 'git config', good.

Keep working on it, it is looking better :-)

This test case doesn't appear to be checking for the verbose output.
No commit is made so it can't check for the presence of a diff.
"check_message message" passes as it did in the test above this (not shown).

No, I don't think parse_options() allows something like that. And we
probably don't want -V for --no-verbose unless it's very often used.

As a courtesy to reviewers, it is helpful to provide a pointer to the
previous submission to give context for the new submission. For
instance, like this [1].

Generally speaking, it is important to respect local style, however,
it is also appropriate to include one or more cleanup patches before
your primary changes in order to bring the code in line with current
practices. Conversion to test_config could be such a cleanup patch.

At this point, after your email commentary but before the actual
patch, you should have a scissor line -->8-- so that "git am" can
extract your patch automatically from the email.

Drop this line. It has no meaning outside of your local repository.

Ditto for the date.

The commit message would read just as well or better without the backquotes.

Considering that the code in this patch has changed since v1, it's
probably not appropriate to add these Reviewed-by: lines.

This is not a new problem, but since you copied and modified the
test_set_editor invocation for your own test (below), it can be
mentioned that $(pwd) should be used rather than $PWD. See discussion
of $(pwd) in t/README. A preparatory patch which fixes this would not
be unwelcome.

write_script (from test-lib-functions.sh) would be a more appropriate
and modern way to compose this script. If you're concerned about style
consistency, a cleanup patch before this one could employ write_script
for the check-for-diff script, as well.

Also, since this script is used by only the one test, current practice
suggests that script creation should be done within the test itself.

Is your intention to add more content to 'file'? If so, use '>>'.

As Jeremiah pointed out, this test is not actually testing if
commit.verbose=true worked since it's not invoking git-commit. In
fact, check_message is testing something unrelated. You probably meant
"git commit --amend" rather than "check_message message"

> +'

> +test_expect_success 'commit does not show verbose diff with --no-verbose' '

As this is the only test which needs check-for-no-diff, it would be
appropriate to move script creation (via write_script) here into the
test itself (unless you plan on adding more tests which invoke the
script).

> +       echo morecontent >file &&

Again, since you're using '>' rather than '>>', you haven't actually
changed the content of the file since the last test, so this code
serves no purpose.

> +       test_config commit.verbose true &&
> +       test_set_editor "$PWD/check-for-no-diff" &&

As noted above, use $(pwd) rather than $PWD.

This invocation of test_set_editor potentially breaks tests following
this one (including tests which may be added in the future) since it
changes the global state established by test_set_editor near the top
of the script. To avoid such a problem, you could invoke
test_set_editor and git-commit in a subshell.

Alternately, current practice would suggest that each test which
requires a particular editor should be responsible for setting it. As
such, a preparatory patch could drop the global test_set_editor and
invoke it instead in each test which requires it. (In fact, there are
a couple tests which are still setting EDITOR manually, and these
could be converted to test_set_editor.)

> +       git commit --amend --no-verbose

You're missing some potential tests, such as:

commit.verbose = <unset> (optional)
commit.verbose = false
--verbose overrides commit.verbose=false

[PATCH v3 0/5] commit: support commit.verbose and --no-verbose

[Caleb Thompson]

This patch allows people to set commit.verbose to implicitly send
--verbose to git-commit. It also introduces --no-verbose to
override the configuration setting.

This version incorporates changes suggested by Eric Sunshine, Duy
Nguyen, and Jeremiah Mahler.

It introduces several cleanup patches to t/t7505-commit-verbose.sh to
bring it closer to the current state of the tests as Eric has explained
them to me, then adds the verbose config and --no-verbose flag.

Why? I see no benefit. Both $PWD and $(pwd) work fine everywhere,
including Windows, and the former is faster, particularly on Windows.

Poor advice on my part when reviewing the previous round. When I had
read in git/t/README (in the distant past):

    When a test checks for an absolute path that a git command
    generated, construct the expected value using $(pwd) rather than
    $PWD, $TEST_DIRECTORY, or $TRASH_DIRECTORY. It makes a difference
    on Windows, where the shell (MSYS bash) mangles absolute path
    names.  For details, see the commit message of 4114156ae9.

I must have missed the word "check" in the first sentence.

I don't know the technical details of why this change is needed.
But someone felt it was important enough to put in t/README.

That someone was I. I appreciate that people study t/README and do not
ignore the sentence.

However, it does not apply to the situation because the path to the editor
is not "generated by a git command and checked for by a test".

That said, it is not wrong to use $(pwd) with test_set_editor, it's just
unnecessarily slow.

Any shell that knows $(...) is pretty sure to have pwd as a built-in.
I don't think Git will run on those kind of ancient shells reverting to
/bin/pwd here.

The autoconf manual (info "(autoconf) Limitations of Builtins") states

'pwd'
     With modern shells, plain 'pwd' outputs a "logical" directory name,
     some of whose components may be symbolic links.  These directory
     names are in contrast to "physical" directory names, whose
     components are all directories.

     Posix 1003.1-2001 requires that 'pwd' must support the '-L'
     ("logical") and '-P' ("physical") options, with '-L' being the
     default.  However, traditional shells do not support these options,
     and their 'pwd' command has the '-P' behavior.

     Portable scripts should assume neither option is supported, and
     should assume neither behavior is the default.  Also, on many hosts
     '/bin/pwd' is equivalent to 'pwd -P', but Posix does not require
     this behavior and portable scripts should not rely on it.

     Typically it's best to use plain 'pwd'.  On modern hosts this
     outputs logical directory names, which have the following
     advantages:

        * Logical names are what the user specified.
        * Physical names may not be portable from one installation host
          to another due to network file system gymnastics.
        * On modern hosts 'pwd -P' may fail due to lack of permissions
          to some parent directory, but plain 'pwd' cannot fail for this
          reason.

     Also please see the discussion of the 'cd' command.

So $PWD is pretty much guaranteed to be the same as $(pwd) and pretty
much guaranteed to _not_ be "unnecessarily slow" when not run in an
inner loop.

However, looking at (info "(autoconf) Special Shell Variables") I see

'PWD'
     Posix 1003.1-2001 requires that 'cd' and 'pwd' must update the
     'PWD' environment variable to point to the logical name of the
     current directory, but traditional shells do not support this.
     This can cause confusion if one shell instance maintains 'PWD' but
     a subsidiary and different shell does not know about 'PWD' and
     executes 'cd'; in this case 'PWD' points to the wrong directory.
     Use '`pwd`' rather than '$PWD'.

Ok, probably Git relies on Posix 1003.1-2001 in other respects so it's
likely not much of an actual issue.

Food for thought:

The original code used <<EOF since it needed $SHELL_PATH to be
evaluated at script creation time, and took special care to escape $1
in the 'grep' invocation since $1 should be evaluated only at script
execution time.

With the change to write_script(), nothing within the here-doc
requires evaluation, yet you are still using the evaluating <<-EOF
form (and manually escaping $1). The intent might be clearer if you
switch to <<-\EOF which suppresses evaluation (and drop the manual
escaping of $1).

The same observation applies to the new write_script() invocation to
create check-for-no-diff in patch 5.

Very good comments.  Thanks.

[PATCH v3 4/5] commit test: test_set_editor in each test

[Caleb Thompson]

t/t7507-commit-verbose.sh was using a global test_set_editor call to
build its environment.

Rather than building global state with test_set_editor at the beginning
of the file, move test_set_editor calls into each test.

Besides being inline with current practices, it also allows the tests
which required GIT_EDITOR=cat to avoid using a subshell and simplify
their logic.

Rather than repeating in prose what the patch itself says more
concisely and precisely, explain the reason for this change. For
instance, you might replace the above two sentences with something
like this (or better):

    Improve robustness against global state changes by having each
    test set up the test-editor it requires rather than relying upon
    the editor set once at script start.

"required" sounds odd here. Perhaps:

    ...which set GIT_EDITOR=cat manually...

This test does not invoke the test-editor at all, so it's misleading
to insert test_set_editor here.

Ditto.

Unnecessary. The editor isn't invoked until the test_must_fail line,
and by then you've already overridden it with 'test_set_editor cat'.

[PATCH v3 5/5] commit: support commit.verbose and --no-verbose

[Caleb Thompson]

Add a new configuration variable commit.verbose to implicitly pass
`--verbose` to `git-commit`. Add `--no-verbose` to commit to negate that
setting.

It appears that these tests still aren't checking to see if the
"verbose" output appears in the commit message.

The editors, `check-for-diff` and `check-for-no-diffs`, are grepping for the
output and lack thereof, respectively.

OK, got it.  The editor, set by test_set_editor, is run as part of
the commit.  Thanks for explaining that.

Some minor style nits...

Use a consistent naming convention for your tests.  verbose=false looks
different than commit.verbose=false at first glance.  Also, since
"commit.verbose=false" is an invalid syntax for a config option, I would
remove the '=' and just make it "commit.verbose false".

Other than the minor style issue I pointed out in another email, it looks
good, and the patch set works properly on my machine.

Great, thanks Jeremiah!

I made that change, and will send up another patch version in the next day or so
while I wait on others who may have input.

I'm really appreciative of everyone's feedback!
