yuuri ed94f549 2021-05-01T20:26:49 diff:add option to ignore blank line changes
Edward Thomson 1d95b59b 2021-04-14T15:47:27 utf8: refactor utf8 functions Move the utf8 functions into a proper namespace `git_utf8` instead of being in the namespaceless `git__` function group. Update them to have out-params first and use `char *` instead of `uint8_t *` to match our API treating strings as `char *` (even if they truly contain `uchar`s inside).
Edward Thomson f673e232 2018-12-27T13:47:34 git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.
Stan Hu 9d83a2b0 2018-02-22T22:55:50 Sanitize the hunk header to ensure it contains UTF-8 valid data The diff driver truncates the hunk header text to 80 bytes, which can truncate 4-byte Unicode characters and introduce garbage characters in the diff output. This change sanitizes the hunk header before it is displayed. This mirrors the test in git: https://github.com/git/git/blob/master/t/t4025-hunk-header.sh Closes https://github.com/libgit2/rugged/issues/716
Carlos Martín Nieto 7e3faf58 2017-10-29T15:05:28 diff: expose the "indent heuristic" in the diff options We default to off, but we might want to consider changing `GIT_DIFF_NORMAL` to include it.
Patrick Steinhardt 0c7f49dd 2017-06-30T13:39:01 Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
Edward Thomson 909d5494 2016-12-29T12:25:15 giterr_set: consistent error messages Error messages should be sentence fragments, and therefore: 1. Should not begin with a capital letter, 2. Should not conclude with punctuation, and 3. Should not end a sentence and begin a new one
Edward Thomson 8d44f8b7 2015-11-24T15:19:59 patch: `patch_diff` -> `patch_generated`
Edward Thomson 804d5fe9 2015-09-11T08:37:12 patch: abstract patches into diff'ed and parsed Patches can now come from a variety of sources - either internally generated (from diffing two commits) or as the results of parsing some external data.

Russell Belfer 96869a4e 2013-12-03T16:45:39 Improve GIT_EUSER handling This adds giterr_user_cancel to return GIT_EUSER and clear any error message that is sitting around. As a result of using that in places, we need to be more thorough with capturing errors that happen inside a callback when used internally. To help with that, this also adds giterr_capture and giterr_restore so that when we internally use a foreach-type function that clears errors and converts them to GIT_EUSER, it is easier to restore not just the return value, but the actual error message text.
Russell Belfer 25e0b157 2013-12-06T15:07:57 Remove converting user error to GIT_EUSER This changes the behavior of callbacks so that the callback error code is not converted into GIT_EUSER and instead we propagate the return value through to the caller. Instead of using the giterr_capture and giterr_restore functions, we now rely on all functions to pass back the return value from a callback. To avoid having a return value with no error message, the user can call the public giterr_set_str or some such function to set an error message. There is a new helper 'giterr_set_callback' that functions can invoke after making a callback which ensures that some error message was set in case the callback did not set one. In places where the sign of the callback return value is meaningful (e.g. positive to skip, negative to abort), only the negative values are returned back to the caller, obviously, since the other values allow for continuing the loop. The hardest parts of this were in the checkout code where positive return values were overloaded as meaningful values for checkout. I fixed this by adding an output parameter to many of the internal checkout functions and removing the overload. This added some code, but it is probably a better implementation. There is some funkiness in the network code where user provided callbacks could be returning a positive or a negative value and we want to rely on that to cancel the loop. There are still a couple places where an user error might get turned into GIT_EUSER there, I think, though none exercised by the tests.
Nick Hengeveld d8e7ffc2 2013-11-18T14:03:25 Add content offset to git_diff_line For additions and deletions, external consumers like subversion can make use of the content offset to generate diffs in their proprietary formats.
Russell Belfer 5de4ec81 2013-10-21T15:36:38 Implement patience and minimal diff flags It seems that to implement these options, we just have to pass the appropriate flags through to the libxdiff code taken from core git. So let's do it (and add a test).

Russell Belfer 3b5f7954 2013-10-21T13:42:42 Create git_diff_line and extend git_diff_hunk Instead of having functions with so very many parameters to pass hunk and line data, this takes the existing git_diff_hunk struct and extends it with more hunk data, plus adds a git_diff_line. Those structs are used to pass back hunk and line data instead of the old APIs that took tons of parameters. Some work that was previously only being done for git_diff_patch creation (scanning the diff content for exact line counts) is now done for all callbacks, but the performance difference should not be noticable.
Russell Belfer 10672e3e 2013-10-15T15:10:07 Diff API cleanup This lays groundwork for separating formatting options from diff creation options. This groups the formatting flags separately from the diff list creation flags and reorders the options. This also tweaks some APIs to further separate code that uses patches from code that just looks at git_diffs.
Russell Belfer 3ff1d123 2013-10-11T14:51:54 Rename diff objects and split patch.h This makes no functional change to diff but renames a couple of the objects and splits the new git_patch (formerly git_diff_patch) into a new header file.
Russell Belfer 360f42f4 2013-06-12T14:18:09 Fix diff header naming issues This makes the git_diff_patch definition private to diff_patch.c and fixes a number of other header file naming inconsistencies to use `git_` prefixes on functions and structures that are shared between files.
Russell Belfer 5dc98298 2013-06-11T11:22:22 Implement regex pattern diff driver This implements the loading of regular expression pattern lists for diff drivers that search for function context in that way. This also changes the way that diff drivers update options and interface with xdiff APIs to make them a little more flexible.
Russell Belfer 114f5a6c 2013-06-10T10:10:39 Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.
