diff*: fix worktree setup

2008-08-29T03:50:10Z

This fixes "git diff", "git diff-files" and "git diff-index" to work correctly under worktree setup. Because diff* family works in many modes and not all of them require worktree, Junio made a nice summary (with a little modification from me): * diff-files is about comparing with work tree, so it obviously needs a work tree; * diff-index also does, except "diff-index --cached" or "diff --cached TREE" * no-index is about random files outside git context, so it obviously doesn't need any work tree; * comparing two (or more) trees doesn't; * comparing two blobs doesn't; * comparing a blob with a random file doesn't; Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

Make usage strings dash-less

2008-07-13T21:12:48Z

When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version. For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh generates a dash-less usage string now. Signed-off-by: Stephan Beyer Signed-off-by: Junio C Hamano

Provide git_config with a callback-data parameter

2008-05-14T19:34:44Z

git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables. With this patch, every callback gets a void * parameter, and it is hoped that this will help the libification effort. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

add a "basic" diff config callback

2008-01-05T00:05:23Z

The diff porcelain uses git_diff_ui_config to set porcelain-ish config options, like automatically turning on color. The plumbing specifically avoids calling this function, since it doesn't want things like automatic color or rename detection. However, some diff options should be set for both plumbing and porcelain. For example, one can still turn on color in git-diff-files using the --color command line option. This means we want the color config from color.diff.* (so that once color is on, we use the user's preferred scheme), but _not_ the color.diff variable. We split the diff config into "ui" and "basic", where "basic" is suitable for use by plumbing (so _most_ things affecting the output should still go into the "ui" part).

diff --check: minor fixups

2007-12-14T07:40:27Z

There is no reason --exit-code and --check-diff must be mutually exclusive, so assign different bits to different results and allow them to be returned from the command. Introduce diff_result_code() to factor out the common code to decide final status code based on diffopt settings and use it everywhere. Update tests to match the above fix. Turning pager off when "diff --check" is used is a regression. Signed-off-by: Junio C Hamano

"diff --check" should affect exit status

2007-12-14T07:05:42Z

"git diff" has a --check option that can be used to check for whitespace problems but it only reported by printing warnings to the console. Now when the --check option is used we give a non-zero exit status, making "git diff --check" nicer to use in scripts and hooks. Signed-off-by: Wincent Colaiuta Signed-off-by: Junio C Hamano

Make the diff_options bitfields be an unsigned with explicit masks.

reverse_diff was a bit-value in disguise, it's merged in the flags now. Signed-off-by: Pierre Habouzit Signed-off-by: Junio C Hamano

War on whitespace

2007-06-07T07:04:01Z

This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

Allow git-diff exit with codes similar to diff(1)

2007-03-14T23:21:19Z

This introduces a new command-line option: --exit-code. The diff programs will return 1 for differences, return 0 for equality, and something else for errors. Signed-off-by: Alex Riesen Signed-off-by: Junio C Hamano

run_diff_{files,index}(): update calling convention.

They used to open and read index themselves, but they now expect their callers to do so. Signed-off-by: Junio C Hamano
