From f245194f9a13d5108c3a59fd4ab1770ae9fd5b65 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 22 May 2009 12:45:29 -0700 Subject: diff: change semantics of "ignore whitespace" options Traditionally, the --ignore-whitespace* options have merely meant to tell the diff output routine that some class of differences are not worth showing in the textual diff output, so that the end user has easier time to review the remaining (presumably more meaningful) changes. These options never affected the outcome of the command, given as the exit status when the --exit-code option was in effect (either directly or indirectly). When you have only whitespace changes, however, you might expect git diff -b --exit-code to report that there is _no_ change with zero exit status. Change the semantics of --ignore-whitespace* options to mean more than "omit showing the difference in text". The exit status, when --exit-code is in effect, is computed by checking if we found any differences at the path level, while diff frontends feed filepairs to the diffcore engine. When "ignore whitespace" options are in effect, we defer this determination until the very end of diffcore transformation. We simply do not know until the textual diff is generated, which comes very late in the pipeline. When --quiet is in effect, various diff frontends optimize by breaking out early from the loop that enumerates the filepairs, when we find the first path level difference; when --ignore-whitespace* is used the above change automatically disables this optimization.

As a side effect, because there is no point showing one change that we happened to have found first, it also enables NO_OUTPUT and EXIT_WITH_STATUS options, making the end result look quiet. Rename the internal option to QUICK to reflect this better; it also makes grepping the source tree much easier, as there are other kinds of QUIET option everywhere.

If you added 96 blank lines, a non-blank line, and then 3 blank lines at the end, only the last 3 lines should trigger the error, not the earlier 96 blank lines. We need to also make sure that the lines are after the last non-blank line in the postimage as well before deciding to paint them.

This function knows two sets of helpers (one for line-oriented diff, another for word diff), and each set has various functions to be called at certain places (e.g. hunk header, context, ...). The function's role is to inspect the incoming line, and dispatch appropriate helpers to produce either line- or word- oriented diff output." * introduce fn_out_consume_word_diff() that is "this is called every time a line worth of diff becomes ready from the lower-level diff routine, and here is what we do to prepare word oriented diff using that line." without touching fn_out_consume() at all. * Do neither of the above, and keep fn_out_consume() to "this is called every time a line worth of diff becomes ready from the lower-level diff routine, and here is what we do to output line oriented diff using that line." but sprinkle a handful of 'are we in word-diff mode? if so do this totally different thing' at random places. This patch is to at least abstract the details of "this totally different thing" out from the main codepath, in order to improve readability. We can later refactor it by introducing fn_out_consume_word_diff(), taking the second route above, but that is a separate topic.

This lets non-core porcelains store arbitrary information in the config file, and it means that configuration files can be shared between new and old versions of git (the old versions might simply ignore certain configuration). The one exception to this is color configuration; if we encounter a color.{diff,branch,status}.$slot variable, we die if it is not one of the recognized slots (presumably as a safety valve for user misconfiguration). This behavior has existed since 801235c (diff --color: use $GIT_DIR/config, 2006-06-24), but hasn't yet caused a problem. No porcelain has wanted to store extra colors, and we once a color area (like color.diff) has been introduced, we've never changed the set of color slots. However, that changed recently with the addition of color.diff.func. Now a user with color.diff.func in their config can no longer freely switch between v1.6.6 and older versions; the old versions will complain about the existence of the variable. This patch loosens the check to match the rest of git-config; unknown color slots are simply ignored. This doesn't fix this particular problem, as the older version (without this patch) is the problem, but it at least prevents it from happening again in the future.

Running through the shell is useful because the user can provide a program with command line arguments, like "antiword -f". It also makes textconv more consistent with other parts of git, most of which run their helpers using the shell. The downside is that textconv helpers with shell metacharacters (like space) in the filename will be broken.

When unpack_callback() is fed a set of tree entries from trees, it inspects the name of the entry and checks if the an index entry with the same name could be hiding behind the current index entry, and (1) if the name appears in the index as a leaf node, it is also fed to the n_way_merge() callback function; (2) if the name is a directory in the index, i.e. there are entries in that are underneath it, then nothing is fed to the n_way_merge() callback function; (3) otherwise, if the name comes before the first eligible entry in the index, the index entry is first unpacked alone. When traverse_trees_recursive() descends into a subdirectory, the cache_bottom pointer is moved to walk index entries within that directory. All of these are omitted for diff-index, which does not even want to be fed an index entry and a tree entry with D/F conflicts. This fixes 3-way read-tree and exposes a bug in other parts of the system in t6035, test #5. The test prepares these three trees: O = HEAD^ 100644 blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 a/b-2/c/d 100644 blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 a/b/c/d 100644 blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 a/x A = HEAD 100644 blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 a/b-2/c/d 100644 blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 a/b/c/d 100644 blob 587be6b4c3f93f93c489c0111bba5596147a26cb a/x B = master 120000 blob a36b77384451ea1de7bd340ffca868249626bc52 a/b 100644 blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 a/b-2/c/d 100644 blob e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 a/x With a clean index that matches HEAD, running git read-tree -m -u --aggressive $O $A $B now yields 120000 a36b77384451ea1de7bd340ffca868249626bc52 3 a/b 100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 0 a/b-2/c/d 100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 1 a/b/c/d 100644 e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 2 a/b/c/d 100644 587be6b4c3f93f93c489c0111bba5596147a26cb 0 a/x which is correct. "master" created "a/b" symlink that did not exist, and removed "a/b/c/d" while HEAD did not do touch either path. Before this series, read-tree did not notice the situation and resolved addition of "a/b" and removal of "a/b/c/d" independently. If A = HEAD had another path "a/b/c/e" added, this merge should conflict but instead it silently resolved "a/b" and then immediately overwrote it to add "a/b/c/e", which was quite bogus.

The information we got from scanning the whole submodule tree the first time can be reused instead. New parameters have been added to diff_change() and diff_addremove(), the information is stored in a new member of struct diff_filespec. Its value is then reused instead of calling is_submodule_modified() again. When no explicit "-dirty" is needed in the output the call to is_submodule_modified() is not necessary when the submodules HEAD already disagrees with the ref of the superproject, as this alone marks it as modified. To achieve that, get_stat_data() got an extra argument.

The argument is a colorbool: "always", "never", or "auto". If no argument is given, "always" is used; --no-color is an alias for --color=never. This makes the command-line interface consistent with other GNU tools, such as `ls' and `grep', and with the git-config color options. Note that, without an argument, --color and --no-color work exactly as before. To implement this, two internal changes were made: 1. Allow the first argument of git_config_colorbool() to be NULL, in which case it returns -1 if the argument isn't "always", "never", or "auto". 2. Add OPT_COLOR_FLAG(), OPT__COLOR(), and parse_opt_color_flag_cb() to the option parsing library. The callback uses git_config_colorbool(), so color.h is now a dependency of parse-options.c.

This always resulted in printing "new commits" for submodules that contained untracked or modified content, even if they did not contain new commits. The reason was that match_stat_with_submodule() did set the "changed" flag for dirty submodules, resulting in two->sha1 being set to the null_sha1 at the call sites, which indicates that new commits are present. This is changed so that when no new commits are present, the same object names are in the sha1 field for both sides of the filepair, and the working tree side will have the "dirty_submodule" flag set when appropriate. For a submodule to be seen as modified even when it just has a dirty work tree, some conditions had to be extended to also check for the "dirty_submodule" flag.

It's particularly bad for a large file which needs to be spooled to disk, but even for small files, the fork+exec overhead can add up for something like "git log -p". This patch uses the notes-cache mechanism to keep a fast cache of textconv output. Caches are stored in refs/notes/textconv/$x, where $x is the userdiff driver defined in gitattributes. Caching is enabled only if diff.$x.cachetextconv is true. In my test repo, on a commit with 45 jpg and avi files changed and a textconv to show their exif tags: [before] $ time git show >/dev/null real 0m13.724s user 0m12.057s sys 0m1.624s [after, first run] $ git config diff.mfo.cachetextconv true $ time git show >/dev/null real 0m14.252s user 0m12.197s sys 0m1.800s [after, subsequent runs] $ time git show >/dev/null real 0m0.352s user 0m0.148s sys 0m0.200s So for a slight (3.8%) cost on the first run, we achieve an almost 40x speed up on subsequent runs.

Long ago, this was sensible as we would need to look at the blobs eventually. These days, however, we may not ever want those blobs if we end up using a textconv cache, and for large binary files (exactly the sort for which you might have a textconv cache), just retrieving the objects can be costly. This patch just pushes the fill_mmfile call a bit later, so we can avoid populating the filespec in some cases. There is one thing to note that looks like a bug but isn't. We push the fill_mmfile down into the first branch of a conditional. It seems like we would need it on the other branch, too, but we don't; fill_textconv does it for us (in fact, before this, we were just writing over the results of the fill_mmfile on that branch). Here's a timing sample on a commit with 45 changed jpgs and avis. The result is fully textconv cached, but we still wasted a lot of time just pulling the blobs from storage. The total size of the blobs (source and dest) is about 180M. [before] $ time git show >/dev/null real 0m0.352s user 0m0.148s sys 0m0.200s [after] $ time git show >/dev/null real 0m0.009s user 0m0.004s sys 0m0.004s And that's on a warm cache. On a cold cache, the "after" case is not much worse, but the "before" case has to do an extra 180M of I/O.

however, for binary files, they store file sizes. Since we store and print these values as ints, a diffstat on a file larger than 2G can show a negative size. Instead, let's use uintmax_t, which should be at least 64 bits on modern platforms.

It makes sure that the smallest possible diff is produced, but that takes quite some time if there are lots of differences that can be expressed in multiple ways. This flag makes a difference for only 0.1% of the non-merge commits in the git repo of Linux, both in terms of diff size and execution time. The patches there are mostly nice and small. SungHyun Nam however reported a case in a different repo where a diff took more than 20 times longer to generate with XDF_NEED_MINIMAL than without. Rebasing became really slow. This patch removes this flag from all callers. The default of xdiff is saner because it has minimal to no impact in the normal case of small diffs and doesn't incur that much of a speed penalty for large ones. A follow-up patch may introduce a command line option to set the flag if the user needs it, similar to GNU diff's -d/--minimal.

And this may happen when we run 'git log --follow' with hard copies finding. That is, the try_to_follow_renames() will run diffcore_std to find the copies, and then 'git log' will issue another diffcore_std, which will reduce 'src->rename_used' and recognize this copy as a rename. This is not what we want. So, I think we really don't need to run diffcore_std more than one time.

The -r option would be an alternative but has problems with lines that are longer than the screen. Therefore stick to the idiom to color each line separately. The problem is, that the result of ill_metainfo() will also be used as an parameter to an external diff driver, so we need to disable coloring in this case. Because coloring is now done inside fill_metainfo() we can simply add this string to the diff header and therefore keep the last newline in the extended header. This results also into the fact that the external diff driver now gets this last newline too. Which is a change in behavior but a good one.

These provide hints that can be used to reconstruct a 3-way merge when applying the patch (see the --3way option to 'git am' for more details). In order for this to work, however, the blob SHA1s must not be abbreviated into ambiguity. This patch eliminates the possible ambiguity by using find_unique_abbrev() to produce the abbreviated SHA1s (instead of blind abbreviation by way of "%.*s").

This may happen e.g. when the submodule is not under the developers control and not all build generated files have been added to .gitignore by the upstream developers. Using the "untracked" parameter for the "--ignore-submodules" option disables checking for untracked content and lets git diff report them as changed only when they have new commits or modified content. Sometimes it is not wanted to have submodules show up as changed when they just contain changes to their work tree. An example for that are scripts which just want to check for submodule commits while ignoring any changes to the work tree. Also users having large submodules known not to change might want to use this option, as the - sometimes substantial - time it takes to scan the submodule work tree(s) is saved.
