The failure case which occurs on teaching git is taught the '-' shorthand is when there exists no branch pointed to by '@{-1}'. But, if there is a file named - in the working tree, the user can be unambiguously assumed to be referring to it while issuing this command. The ambiguous case occurs when the @{-1} branch exists and file named '-' also exists in the working tree. This are also treated as a failure case but here the user is given advice as to how he can proceed. Another potentially tricky case is when the file '@{-1}' exists. In this case, the command should succeed as the user doesn't mention the file '@{-1}' and can be safely assumed to be referring to the @{-1} branch. Add tests to check the handling of these cases. Also add a test to verify that reset - behaves like reset @{-1} when none of the above cases are true.

I have made modifications suggested by you. I have also acted on Matthieu's suggestions on the archive. Please let me know if there is something else I should add. I have also removed one irrelevant test from which we come to know of nothing new. t/t7102-reset.sh | 75 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 75 insertions(+) diff --git a/t/t7102-reset.sh b/t/t7102-reset.sh index 98bcfe2..f5a8e76 100755 --- a/t/t7102-reset.sh +++ b/t/t7102-reset.sh @@ -568,4 +568,79 @@ test_expect_success 'reset --mixed sets up work tree' ' test_cmp expect actual ' +test_expect_success 'reset - with no @{-1} branch should fail' ' + test_when_finished rm -rf new && + git init new && + ( + cd new && + test_must_fail git reset - 2>../actual + ) && + test_i18ngrep "bad flag" actual +' + +test_expect_success 'reset - with no @{-1} branch and file named - should succeed' ' + test_when_finished rm -rf new && + >expected && + git init new && + ( + cd new && + echo "Hello" >- && + git add - && + git reset - >../actual + ) && + test_cmp expected actual +' + +test_expect_success 'reset - with @{-1} branch and file named - should fail' ' + test_when_finished rm -rf new && + git init new && + ( + cd new && + echo "Hello" >- && + git add - && + git commit -m "first_commit" && + git checkout -b new_branch && + >- && + git add - && + test_must_fail git reset - 2>../actual + ) && + test_i18ngrep "ambiguous argument" actual +' + +test_expect_success 'reset - with @{-1} branch and file named @{-1} should succeed' ' + test_when_finished rm -rf new && + git init new && + ( + cd new && + echo "Hello" >@{-1} && + git add @{-1} && + git commit -m "first_commit" && + git checkout -b new_branch && + >@{-1} && + git add @{-1} && + git reset - >../actual + ) && + test_i18ngrep "Unstaged" actual +' + +test_expect_success 'reset - with @{-1} branch and no file named - should succeed' ' + test_when_finished rm -rf new && + git init new && + ( + cd new && + echo "Hey" >new_file && + git add new_file && + git commit -m "first_commit" && + git checkout -b new_branch && + >new_file && + git add new_file && + git reset - && + git status -uno >actual && + git add new_file && + git reset @{-1} && + git status -uno >expected && + test_cmp actual expected + ) +' + test_done -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
