* use SWAP macroRené Scharfe2017-01-30
| | | | | | | | | | | | Apply the semantic patch swap.cocci to convert hand-rolled swaps to use the macro SWAP. The resulting code is shorter and easier to read, the object code is effectively unchanged. The patch for object.c had to be hand-edited in order to preserve the comment before the change; Coccinelle tried to eat it for some reason.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * diff: skip implicit no-index check when given --no-indexJeff King2016-09-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

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).

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).

* | diff --stat: use the full terminal widthZbigniew Jędrzejewski-Szmek2012-03-01
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* use struct sha1_array in diff_tree_combined()René Scharfe2011-12-17
| | | | | | | | | Maintaining an array of hashes is easier using sha1_array than open-coding it. This patch also fixes a leak of the SHA1 array in diff_tree_combined_merge(). Signed-off-by: René Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* cast variable in call to free() in builtin/diff.c and submodule.cÆvar Arnfjörð Bjarmason2011-11-06
| | | | | | | | | | | | | | | | | | | | | Both of these free() calls are freeing a "const unsigned char (*)[20]" type while free() expects a "void *". This results in the following warning under clang 2.9: builtin/diff.c:185:7: warning: passing 'const unsigned char (*)[20]' to parameter of type 'void *' discards qualifiers free(parent); ^~~~~~ submodule.c:394:7: warning: passing 'const unsigned char (*)[20]' to parameter of type 'void *' discards qualifiers free(parents); ^~~~~~~ This free()-ing without a cast was added by Jim Meyering to builtin/diff.c in v1.7.6-rc3~4 and later by Fredrik Gustafsson in submodule.c in v1.7.7-rc1~25^2.

* want_color: automatically fallback to color.uiJeff King2011-08-19
| | | | | | | | | | | | | | | | | | | | | 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.
