2018-08-29convert "oidcmp() == 0" to oideq()Jeff King1-1/+1
Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

"git diff" compares the index and the working tree. For paths added with intent-to-add bit, the command shows the full contents of them as added, but the paths themselves were not marked as new files. They are now shown as new by default. "git apply" learned the "--intent-to-add" option so that an otherwise working-tree-only application of a patch will add new paths to the index marked with the "intent-to-add" bit. * nd/diff-apply-ita: apply: add --intent-to-add t2203: add a test about "diff HEAD" case diff: turn --ita-invisible-in-index on by default diff: ignore --ita-[in]visible-in-index when diffing worktree-to-tree

2018-04-11treewide: replace maybe_tree with accessor methodsDerrick Stolee1-1/+1
In anticipation of making trees load lazily, create a Coccinelle script (contrib/coccinelle/commit.cocci) to ensure that all references to the 'maybe_tree' member of struct commit are either mutations or accesses through get_commit_tree() or get_commit_tree_oid().

2018-04-11treewide: rename tree to maybe_treeDerrick Stolee1-1/+1
Using the commit-graph file to walk commit history removes the large cost of parsing commits during the walk. This exposes a performance issue: lookup_tree() takes a large portion of the computation time, even when Git never uses those trees. In anticipation of lazy-loading these trees, rename the 'tree' member of struct commit to 'maybe_tree'. This serves two purposes: it hints at the future role of possibly being NULL even if the commit has a valid tree, and it allows for unambiguous transformation from simple member access (i.e. commit->maybe_tree) to method access.

2017-05-24diff: use blob path for blob/file diffsJeff 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).

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: pass whole pending entry in blobinfoJeff 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 repositoryJeff 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-indexJeff 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_argvAlexander 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 defaultMatthieu 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.

2012-07-29diff: do not use null sha1 as a sentinel valueJeff King1-2/+6
The diff code represents paths using the diff_filespec struct. This struct has a sha1 to represent the sha1 of the content at that path, as well as a sha1_valid member which indicates whether its sha1 field is actually useful. If sha1_valid is not true, then the filespec represents a working tree file (e.g., for the no-index case, or for when the index is not up-to-date). The diff_filespec is only used internally, though. At the interfaces to the diff subsystem, callers feed the sha1 directly, and we create a diff_filespec from it. It's at that point that we look at the sha1 and decide whether it is valid or not; callers may pass the null sha1 as a sentinel value to indicate that it is not. We should not typically see the null sha1 coming from any other source (e.g., in the index itself, or from a tree). However, a corrupt tree might have a null sha1, which would cause "diff --patch" to accidentally diff the working tree version of a file instead of treating it as a blob. This patch extends the edges of the diff interface to accept a "sha1_valid" flag whenever we accept a sha1, and to use that flag when creating a filespec. In some cases, this means passing the flag through several layers, making the code change larger than would be desirable. One alternative would be to simply die() upon seeing corrupted trees with null sha1s. However, this fix more directly addresses the problem (while bogus sha1s in a tree are probably a bad thing, it is really the sentinel confusion sending us down the wrong code path that is what makes it devastating). And it means that git is more capable of examining and debugging these corrupted trees. For example, you can still "diff --raw" such a tree to find out when the bogus entry was introduced; you just cannot do a "--patch" diff (just as you could not with any other corrupted tree, as we do not have any content to diff).

2012-06-15fix pager.diff with diff --no-indexJeff King1-7/+17
git-diff does not rely on the git wrapper to setup its pager; instead, it sets it up on its own after seeing whether --quiet or --exit-code has been specified. After diff_no_index was split off from cmd_diff, commit b3fde6c (git diff --no-index: default to page like other diff frontends, 2008-05-26) duplicated the one-liner from cmd_diff to turn on the pager. Later, commit 8f0359f (Allow pager of diff command be enabled/disabled, 2008-07-21) taught the the version in cmd_diff to respect the pager.diff config, but the version in diff_no_index was left behind. This meant that git -c pager.diff=0 diff a b would not use a pager, but git -c pager.diff=0 diff --no-index a b would. Let's fix it by factoring out a common function. While we're there, let's update the antiquated comment, which claims that the pager interferes with propagating the exit code; this has not been the case since ea27a18 (spawn pager via run_command interface, 2008-07-22).

2012-03-01diff --stat: use the full terminal widthZbigniew Jędrzejewski-Szmek1-0/+3
Default to the real terminal width for diff --stat output, instead of the hard-coded 80 columns. Some projects (especially in Java), have long filename paths, with nested directories or long individual filenames. When files are renamed, the filename part in stat output can be almost useless. If the middle part between { and } is long (because the file was moved to a completely different directory), then most of the path would be truncated. It makes sense to detect and use the full terminal width and display full filenames if possible. The are commands like diff, show, and log, which can adapt the output to the terminal width. There are also commands like format-patch, whose output should be independent of the terminal width. Since it is safer to use the 80-column default, the real terminal width is only used if requested by the calling code by setting diffopts.stat_width=-1. Normally this value is 0, and can be set by the user only to a non-negative value, so -1 is safe to use internally. This patch only changes the diff builtin to use the full terminal width.

All of the "do we want color" flags default to -1 to indicate that we don't have any color configured. This value is handled in one of two ways: 1. In porcelain, we check early on whether the value is still -1 after reading the config, and set it to the value of color.ui (which defaults to 0). 2. In plumbing, it stays untouched as -1, and want_color defaults it to off. This works fine, but means that every porcelain has to check and reassign its color flag. Now that want_color gives us a place to put this check in a single spot, we can do that, simplifying the calling code.

2011-02-07diff: support --cached on unborn branchesNguyễn Thái Ngọc Duy1-2/+5
"git diff --cached" (without revision) used to mean "git diff --cached HEAD" (i.e. the user was too lazy to type HEAD). This "correctly" failed when there was no commit yet. But was that correctness useful? This patch changes the definition of what particular command means. It is a request to show what _would_ be committed without further "git add". The internal implementation is the same "git diff --cached HEAD" when HEAD exists, but when there is no commit yet, it compares the index with an empty tree object to achieve the desired result.

This was the only occurence of that usage, and square brackets are sufficient and already well-established for that purpose. Signed-off-by: Štěpán Němec <stepnem@gmail.com> Acked-by: Sverre Rabbelier <srabbelier@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-08-09Submodules: Use "ignore" settings from .gitmodules too for diff and statusJens Lehmann1-0/+2
The .gitmodules file is parsed for "submodule.<name>.ignore" entries before looking for them in .git/config. Thus settings found in .git/config will override those from .gitmodules, thereby allowing the local developer to ignore settings given by the remote side while also letting upstream set defaults for those users who don't have special needs.

2010-02-22Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds1-0/+425
This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
