| * | | | diff.c: color moved lines differently, plain modeStefan Beller2017-06-301-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the 'plain' mode for move detection of code. This omits the checking for adjacent blocks, so it is not as useful. If you have a lot of the same blocks moved in the same patch, the 'Zebra' would end up slow as it is O(n^2) (n is number of same blocks). So this may be useful there and is generally easy to add. Instead be very literal at the move detection, do not skip over short blocks here. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

To that end, color blocks that are moved within the same patch differently. For example (OM, del, add, and NM are different colors): [OM] -void sensitive_stuff(void) [OM] -{ [OM] - if (!is_authorized_user()) [OM] - die("unauthorized"); [OM] - sensitive_stuff(spanning, [OM] - multiple, [OM] - lines); [OM] -} void another_function() { [del] - printf("foo"); [add] + printf("bar"); } [NM] +void sensitive_stuff(void) [NM] +{ [NM] + if (!is_authorized_user()) [NM] + die("unauthorized"); [NM] + sensitive_stuff(spanning, [NM] + multiple, [NM] + lines); [NM] +} However adjacent blocks may be problematic. For example, in this potentially malicious patch, the swapping of blocks can be spotted: [OM] -void sensitive_stuff(void) [OM] -{ [OMA] - if (!is_authorized_user()) [OMA] - die("unauthorized"); [OM] - sensitive_stuff(spanning, [OM] - multiple, [OM] - lines); [OMA] -} void another_function() { [del] - printf("foo"); [add] + printf("bar"); } [NM] +void sensitive_stuff(void) [NM] +{ [NMA] + sensitive_stuff(spanning, [NMA] + multiple, [NMA] + lines); [NM] + if (!is_authorized_user()) [NM] + die("unauthorized"); [NMA] +} If the moved code is larger, it is easier to hide some permutation in the code, which is why some alternative coloring is needed. This patch implements the first mode: * basic alternating 'Zebra' mode This conveys all information needed to the user. Defer customization to later patches. First I implemented an alternative design, which would try to fingerprint a line by its neighbors to detect if we are in a block or at the boundary. This idea iss error prone as it inspected each line and its neighboring lines to determine if the line was (a) moved and (b) if was deep inside a hunk by having matching neighboring lines. This is unreliable as the we can construct hunks which have equal neighbors that just exceed the number of lines inspected. (Think of 'AXYZBXYZCXYZD..' with each letter as a line, that is permutated to AXYZCXYZBXYZD..'). Instead this provides a dynamic programming greedy algorithm that finds the largest moved hunk and then has several modes on highlighting bounds. A note on the options '--submodule=diff' and '--color-words/--word-diff': In the conversion to use emit_line in the prior patches both submodules as well as word diff output carefully chose to call emit_line with sign=0. All output with sign=0 is ignored for move detection purposes in this patch, such that no weird looking output will be generated for these cases. This leads to another thought: We could pass on '--color-moved' to submodules such that they color up moved lines for themselves. If we'd do so only line moves within a repository boundary are marked up. It is useful to have moved lines colored, but there are annoying corner cases, such as a single line moved, that is very common. For example in a typical patch of C code, we have closing braces that end statement blocks or functions. While it is technically true that these lines are moved as they show up elsewhere, it is harmful for the review as the reviewers attention is drawn to such a minor side annoyance. For now let's have a simple solution of hardcoding the number of moved lines to be at least 3 before coloring them. Note, that the length is applied across all blocks to find the 'lonely' blocks that pollute new code, but do not interfere with a permutated block where each permutation has less lines than 3.

| * | | | diff.c: buffer all output if asked toStefan Beller2017-06-301-2/+107

It is set internally in diff.c when necessary. We'll have a new struct 'emitted_string' in diff.c which will be used to buffer each line. The emitted_string will duplicate the memory of the line to buffer as that is easiest to reason about for now. In a future patch we may want to decrease the memory usage by not duplicating all output for buffering but rather we may want to store offsets into the file or in case of hunk descriptions such as the similarity score, we could just store the relevant number and reproduce the text later on. This approach was chosen as a first step because it is quite simple compared to the alternative with less memory footprint. emit_diff_symbol factors out the emission part and depending on the diff_options->emitted_symbols the emission will be performed directly when calling emit_diff_symbol or after the whole process is done, i.e. by buffering we have add the possibility for a second pass over the whole output before doing the actual output. In 6440d34 (2012-03-14, diff: tweak a _copy_ of diff_options with word-diff) we introduced a duplicate diff options struct for word emissions as we may have different regex settings in there. When buffering the output, we need to operate on just one buffer, so we have to copy back the emissions of the word buffer into the main buffer. Unconditionally enable output via buffer in this patch as it yields a great opportunity for testing, i.e. all the diff tests from the test suite pass without having reordering issues (i.e. only parts of the output got buffered, and we forgot to buffer other parts). The test suite passes, which gives confidence that we converted all functions to use emit_string for output.

Only DIFF_SYMBOL_SUBMODULE_PIPETHROUGH contains color, the other symbols are for embedding the submodule output into the superprojects output. Remove the colors from the function signatures, as all the coloring decisions will be made either inside the child process or the final emit_diff_symbol, but not in the functions driving the submodule diff.

There are different approaches to buffer all output such as: * Buffering on the char level, i.e. we'd have a char[] which would grow at approximately 80 characters a line. This would keep the output completely unstructured, but might be very easy to implement, such as redirecting all output to a temporary file and working off that. The later passes over the buffer are quite complicated though, because we have to parse back any output and then decide if it should be modified. * Buffer on a line level. As the output is mostly line oriented already, this would make sense, but it still is a bit awkward as we'd have to make sense of it again by looking at the first characters of a line to decide what part of a diff a line is. * Buffer semantically. Imagine there is a formal grammar for the diff output and we'd keep the symbols of this grammar around. This keeps the highest level of structure in the buffered data, such that the actual memory requirements are less than say the first option. Instead of buffering the characters of the line, we'll buffer what we intend to do plus additional information for the specifics. An output of diff --git a/new.txt b/new.txt index fa69b07..412428c 100644 Binary files a/new.txt and b/new.txt differ could be buffered as DIFF_SYMBOL_DIFF_START + new.txt DIFF_SYMBOL_INDEX_MODE + fa69b07 412428c "non-executable" flag DIFF_SYMBOL_BINARY_FILES + new.txt This and the following patches introduce the third option of buffering by first moving any output to emit_diff_symbol, and then introducing the buffering in this function.

It also added a facility to define a custom callback function to make it possible to extend it to non UTF-8 encodings. During the following 8 1/2 years, nobody found need for this custom callback facility. A custom callback function is a wrong design to use here anyway---if your contents need support for non UTF-8 encoding, you shouldn't have to write a custom function and recompile Git to plumb it in. A better approach would be to extend sane_truncate_line() function and have a new member in emit_callback to conditionally trigger it. Signed-off-by: Junio C Hamano <gitster@pobox.com>

When we introduced color.ui, we put it in the same boat: commands had to manually respect it by using git_color_config() or its git_color_default_config() convenience wrapper. But in 4c7f1819b (make color.ui default to 'auto', 2013-06-10), that changed. Since then, we default color.ui to auto in all programs, meaning that even plumbing commands like "git diff-tree --pretty" might colorize the output. Nobody seems to have complained in the intervening years, presumably because the "is stdout a tty" check does a good job of catching the right cases. But that leaves an interesting curiosity: color.ui defaults to auto even in plumbing, but you can't actually _disable_ the color via config. So if you really hate color and set "color.ui" to false, diff-tree will still show color (but porcelain like git-diff won't). Nobody noticed that either, probably because very few people disable color. One could argue that the plumbing should _always_ disable color unless an explicit --color option is given on the command line. But in practice, this creates a lot of complications for scripts which do want plumbing to show user-visible output. They can't just pass "--color" blindly; they need to check the user's config and decide what to send. Given that nobody has complained about the current behavior, let's assume it's a good path, and follow it to its conclusion: supporting color.ui everywhere. Note that you can create havoc by setting color.ui=always in your config, but that's more or less already the case. We could disallow it entirely, but it is handy for one-offs like: git -c color.ui=always foo >not-a-tty when "foo" does not take a --color option itself.

In some other places, it's just less code (not as clearly a win as the previous case but still is). The only slight regresssion is in remote-testsvn, where we don't report the file class (marks files) in the error messages anymore.

Quite the opposite, all feedback we got was positive. Turn it on by default. Users who dislike the feature can turn it off by setting diff.indentHeuristic (which also configures plumbing commands, see prior patches). The change to t/t4051-diff-function-context.sh is needed because the heuristic shifts the changed hunk in the patch. To get the same result regardless of the heuristic configuration, we modify the test file differently: We insert a completely new line after line 2, instead of simply duplicating it.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This heuristic was originally introduced as an experimental feature, and therefore part of the UI configuration. But the user often sees diffs generated by plumbing commands like diff-tree. Moving the indent heuristic into diff's basic configuration prepares the way for diff plumbing commands to respect the setting. The heuristic itself merely makes the diffs more aesthetically pleasing, without changing their correctness. Scripts that rely on the diff plumbing commands should not care whether or not the heuristic is employed.
