diff: move doc to diff.h and diffcore.h

2019-11-18T06:21:28Z

Move the documentation from Documentation/technical/api-diff.txt to both diff.h and diffcore.h as it's easier for the developers to find the usage information beside the code instead of looking for it in another doc file. Also documentation/technical/api-diff.txt is removed because the information it has is now redundant and it'll be hard to keep it up to date and synchronized with the documentation in the header files. There are three members documented in the doc file that weren't found in the header files, assuming the doc wasn't up to date and the members no longer exist: touched_flags, COLOR_DIFF_WORDS and QUIET.

diff: export diffstat interface

2019-11-14T02:10:04Z

Make the diffstat interface (namely, the diffstat_t struct and compute_diffstat) no longer be internal to diff.c and allow it to be used by other parts of git. This is helpful for code that may want to easily extract information from files using the diff machinery, while flushing it differently from how the show_* functions used by diff_flush() do it. One example is the builtin implementation of git-add--interactive's status.

patch-id: convert to use the_hash_algo

Convert the two separate patch-id implementations to use the_hash_algo in their implementation. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

range-diff: suppress line count in outer diff

2019-07-11T21:29:27Z

The line count in the outer diff's hunk headers of a range diff is not all that interesting. It merely shows how far along the inner diff are on both sides. That number is of no use for human readers, and range-diffs are not meant to be machine readable. In a subsequent commit we're going to add some more contextual information such as the filename corresponding to the diff to the hunk headers. Remove the unnecessary information, and just keep the "@@" to indicate that a new hunk of the outer diff is starting. Signed-off-by: Thomas Gummerer Signed-off-by: Junio C Hamano

Merge branch 'sb/format-patch-base-patch-id-fix'

2019-06-13T20:18:46Z

The "--base" option of "format-patch" computed the patch-ids for prerequisite patches in an unstable way, which has been updated to compute in a way that is compatible with "git patch-id --stable". * sb/format-patch-base-patch-id-fix: format-patch: make --base patch-id output stable format-patch: inform user that patch-id generation is unstable

Merge branch 'nd/diff-parseopt'

2019-05-30T17:50:44Z

A brown-paper-bag bugfix to a change already in 'master'. * nd/diff-parseopt: parse-options: check empty value in OPT_INTEGER and OPT_ABBREV diff-parseopt: restore -U (no argument) behavior diff-parseopt: correct variable types that are used by parseopt

diff-parseopt: correct variable types that are used by parseopt

2019-05-29T18:04:30Z

Most number-related OPT_ macros store the value in an 'int' variable. Many of the variables in 'struct diff_options' have a different type, but during the conversion to using parse_options() I failed to notice and correct. The problem was reported on s360x which is a big-endian architechture. The variable to store '-w' option in this case is xdl_opts, 'long' type, 8 bytes. But since parse_options() assumes 'int' (4 bytes), it will store bits in the wrong part of xdl_opts. The problem was found on little-endian platforms because parse_options() will accidentally store at the right part of xdl_opts. There aren't much to say about the type change (except that 'int' for xdl_opts should still be big enough, since Windows' long is the same size as 'int' and nobody has complained so far). Some safety checks may be implemented in the future to prevent class of bugs. Reported-by: Todd Zullinger Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

format-patch: make --base patch-id output stable

2019-05-08T10:27:43Z

We weren't flushing the context each time we processed a hunk in the patch-id generation code in diff.c, but we were doing that when we generated "stable" patch-ids with the 'patch-id' tool. Let's port that similar logic over from patch-id.c into diff.c so we can get the same hash when we're generating patch-ids for 'format-patch --base=' types of command invocations.

Merge branch 'nd/diff-parseopt-4'

2019-04-25T07:41:12Z

Fourth batch to teach the diff machinery to use the parse-options API. * nd/diff-parseopt-4: am: avoid diff_opt_parse() diff --no-index: use parse_options() instead of diff_opt_parse() range-diff: use parse_options() instead of diff_opt_parse() diff.c: allow --no-color-moved-ws diff-parseopt: convert --color-moved-ws diff-parseopt: convert --[no-]color-moved diff-parseopt: convert --inter-hunk-context diff-parseopt: convert --no-prefix diff-parseopt: convert --line-prefix diff-parseopt: convert --[src|dst]-prefix diff-parseopt: convert --[no-]abbrev diff-parseopt: convert --diff-filter diff-parseopt: convert --find-object diff-parseopt: convert -O diff-parseopt: convert --pickaxe-all|--pickaxe-regex diff-parseopt: convert -S|-G diff-parseopt: convert -l diff-parseopt: convert -z diff-parseopt: convert --ita-[in]visible-in-index diff-parseopt: convert --ws-error-highlight
