2017-05-24diff: use blob path for blob/file diffsLibravatar Jeff King1-1/+2
When we diff a blob against a working tree file like: git diff HEAD:Makefile Makefile we always use the working tree filename for both sides of the diff. In most cases that's fine, as the two would be the same anyway, as above. And until recently, we used the "name" for the blob, not the path, which would have the messy "HEAD:" on the beginning. But when they don't match, like: git diff HEAD:old_path new_path it makes sense to show both names. This patch uses the blob's path field if it's available, and otherwise falls back to using the filename (in preference to the blob's name, which is likely to be garbage like a raw sha1).

2017-05-24diff: use pending "path" if it is availableLibravatar Jeff King1-1/+6
There's a subtle distinction between "name" and "path" for a blob that we resolve: the name is what the user told us on the command line, and the path is what we traversed when finding the blob within a tree (if we did so). When we diff blobs directly, we use "name", but "path" is more likely to be useful to the user (it will find the correct .gitattributes, and give them a saner diff header). We still have to fall back to using the name for some cases (i.e., any blob reference that isn't of the form tree:path). That's the best we can do in such a case.

2017-05-24diff: use the word "path" instead of "name" for blobsLibravatar Jeff King1-7/+7

2017-05-24diff: pass whole pending entry in blobinfoLibravatar Jeff King1-23/+15
When diffing blobs directly, git-diff picks the blobs out of the rev_info's pending array and copies the relevant bits to a custom "struct blobinfo". But the pending array entry already has all of this information (and more, which we'll use in future patches). Let's just pass the original entry instead. In practice, these two blobs are probably adjacent in the revs->pending array, and we could just pass the whole array. But the current code is careful to pick each blob out separately and put it into another array, so we'll continue to do so and make our own array-of-pointers.

2016-09-13diff: always try to set up the repositoryLibravatar Jeff King1-2/+2
If we see an explicit "--no-index", we do not bother calling setup_git_directory_gently() at all. This means that we may miss out on reading repo-specific config. It's arguable whether this is correct or not. If we were designing from scratch, making "git diff --no-index" completely ignore the repository makes some sense. But we are nowhere near scratch, so let's look at the existing behavior: 1. If you're in the top-level of a repository and run an explicit "diff --no-index", the config subsystem falls back to reading ".git/config", and we will respect repo config. 2. If you're in a subdirectory of a repository, then we still try to read ".git/config", but it generally doesn't exist. So "diff --no-index" there does not respect repo config. 3. If you have $GIT_DIR set in the environment, we read and respect $GIT_DIR/config, 4. If you run "git diff /tmp/foo /tmp/bar" to get an implicit no-index, we _do_ run the repository setup, and set $GIT_DIR (or respect an existing $GIT_DIR variable). We find the repo config no matter where we started, and respect it. So we already respect the repository config in a number of common cases, and case (2) is the only one that does not. And at least one of our tests, t4034, depends on case (1) behaving as it does now (though it is just incidental, not an explicit test for this behavior). So let's bring case (2) in line with the others by always running the repository setup, even with an explicit "--no-index". We shouldn't need to change anything else, as the implicit case already handles the prefix. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2016-09-13diff: skip implicit no-index check when given --no-indexLibravatar Jeff King1-12/+13
We can invoke no-index mode in two ways: by an explicit request from the user, or implicitly by noticing that we have two paths, and at least one is outside the repository. If the user already told us --no-index, there is no need for us to do the implicit test at all. However, we currently do, and downgrade our "explicit" to DIFF_NO_INDEX_IMPLICIT. This doesn't have any user-visible behavior, though it's not immediately obvious why. We only trigger the implicit check when we have exactly two non-option arguments. And the only code that cares about implicit versus explicit is an error message that we show when we _don't_ have two non-option arguments. However, it's worth fixing anyway. Besides being slightly more efficient, it makes the code easier to follow, which will help when we modify it in future patches.

2016-05-13diff: run arguments through precompose_argvLibravatar Alexander Rinass1-0/+1
When running diff commands, a pathspec containing decomposed unicode code points is not converted to precomposed unicode form under Mac OS X, but we normalize the paths in the index and the history to precomposed form on that platform. As a result, the pathspec would not match and no diff is shown. Unlike many builtin commands, the "diff" family of commands do not use parse_options(), which is how other builtin commands indirectly call precompose_argv() to normalize argv[] into precomposed form on Mac OSX. Teach these commands to call precompose_argv() themselves. Note that precomopose_argv() normalizes not just paths but all command line arguments, so things like "git diff -G $string" when $string has the decomposed form would first be normalized into the precomposed form and would stop hitting the same string in the decomposed form in the diff output with this change. It is not a problem per-se, as "log" family of commands already use parse_options() and call precompose_argv()--we can think of this change as making the "diff" family of commands behave in a similar way as the commands in the "log" family.

2016-02-25diff: activate diff.renames by defaultLibravatar Matthieu Moy1-0/+1
Rename detection is a very convenient feature, and new users shouldn't have to dig in the documentation to benefit from it. Potential objections to activating rename detection are that it sometimes fail, and it is sometimes slow. But rename detection is already activated by default in several cases like "git status" and "git merge", so activating diff.renames does not fundamentally change the situation. When the rename detection fails, it now fails consistently between "git diff" and "git status". This setting does not affect plumbing commands, hence well-written scripts will not be affected.

git diff --no-index ... currently reads the index, during setup, when calling gitmodules_config(). This results in worse performance when the index is not actually needed. This patch avoids calling gitmodules_config() when the --no-index option is given. The times for executing "git diff --no-index" in the WebKit repository are improved as follows: Test HEAD~3 HEAD ------------------------------------------------------------------ 4001.1: diff --no-index 0.24(0.15+0.09) 0.01(0.00+0.00) -95.8% An additional improvement of this patch is that "git diff --no-index" no longer breaks when the index file is corrupt, which makes it possible to use it for investigating the broken repository. To improve the possible usage as investigation tool for broken repositories, setup_git_directory_gently() is also not called when the --no-index option is given. Also add a test to guard against future breakages, and a performance test to show the improvements.

2013-12-12diff: move no-index detection to builtin/diff.cLibravatar Thomas Gummerer1-3/+49
Currently the --no-index option is parsed in diff_no_index(). Move the detection if a no-index diff should be executed to builtin/diff.c, where we can use it for executing diff_no_index() conditionally. This will also allow us to execute other operations conditionally, which will be done in the next patch. There are no functional changes.

2013-11-20diff: restrict pathspec limitations to diff b/f case onlyLibravatar Nguyễn Thái Ngọc Duy1-10/+7
builtin_diff_b_f() needs a path, not pathspec. Other modes in diff can deal with pathspec just fine. But because of the current GUARD_PATHSPEC() location, other modes also reject :(glob) and :(icase). Move GUARD_PATHSPEC(), and the "path" assignment statement, which is the reason of this GUARD_PATHSPEC(), inside builtin_diff_b_f().

2013-07-15guard against new pathspec magic in pathspec matching codeLibravatar Nguyễn Thái Ngọc Duy1-0/+2
GUARD_PATHSPEC() marks pathspec-sensitive code, basically all those that touch anything in 'struct pathspec' except fields "nr" and "original". GUARD_PATHSPEC() is not supposed to fail. It's mainly to help the designers catch unsupported codepaths. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
