Thank you.

I agree with Johannes Schindelin once said "a signoff _has_ to be a conscious
act, or else  it will lose its meaning."
I think I shouldn't add this configuration variable.

When add configuration variable for sign-off to format-patch have some 
discussion:

There is more discussion about this at
https://public-inbox.org/git/1482946838-28779-1-git-send-email-ehabk...@redhat.com/
specifically
https://public-inbox.org/git/xmqqtw9m5s5m@gitster.mtv.corp.google.com/

Not sure if there was any other reasons and discussions brought up
since then, but that discussion seems to not favor patches that
add .signoff options.

Thanks,
Stefan

I just skimmed this, but just to this question. I don't think we need to
worry about 2 v.s. 6 tests having an impact on Windows performance, it's
just massive amounts of tests like my in-flight wildmatch test series
that really matter.

But if we are worring about 2 v.s. 6 there's always my in-flight
EXPENSIVE_ON_WINDOWS prereq :)

This commentary explains why this feature is desirable, therefore it
would be a good idea to include this in the commit message itself.

The bodies of these test are quite noisy, doing a lot of work that isn't
really necessary, which makes it difficult to figure out what is really
being tested. Other tests in this script already check that the commit
message is properly formatted when Signed-off-by: is inserted so you
don't need to repeat all that boilerplate here.

Instead, you are interested only in whether or not Signed-off-by: has
been added to the message. For that purpose, you can use a simple 'grep'
expression.

The amount of copy/paste code in these six tests is also unfortunate.
Rather than merely repeating the same code over and over, you could
instead parameterize the test. For instance, you could run all six tests
via a simple for-loop:

--- >8 ---
for cfg in true false
do
for opt in '' --signoff --no-signoff
do
case "$opt:$cfg" in
--signoff:*|:true) expect= ;;
--no-signoff:*|:false) expect=! ;;
esac
test_expect_success "commit.signoff=$cfg & ${opt:---signoff omitted}" '
git -c commit.signoff=$cfg commit --allow-empty -m x $opt &&
eval "$expect git log -1 --format=%B | grep ^Signed-off-by:"
'
done
done
--- >8 ---

A final consideration is that tests run slowly on Windows, and although
it's nice to be thorough by testing all six combinations, you can
probably exercise the new code sufficiently by instead testing just two
combinations. For instance, instead of all six combinations, test just
these two:

--- >8 ---
test_expect_success 'commit.signoff=true & --signoff omitted' '
git -c commit.signoff=true commit --allow-empty -m x &&
git log -1 --format=%B | grep ^Signed-off-by:
'

test_expect_success 'commit.signoff=true & --no-signoff' '
git -c commit.signoff=true commit --allow-empty -m x --no-signoff &&
! git log -1 --format=%B | grep ^Signed-off-by:
'

[GSoC][PATCH] commit: add a commit.signOff config variable

2018-02-03 Thread Chen Jingpiao 
Add the commit.signOff configuration variable to use the -s or --signoff
option of git commit by default.

Signed-off-by: Chen Jingpiao 
---

Though we can configure signoff using format.signOff variable. Someone like to
add Signed-off-by line by the committer.
