merge: add merge.renames config setting

2018-05-08T07:19:41Z

Add the ability to control rename detection for merge via a config setting. This setting behaves the same and defaults to the value of diff.renames but only applies to merge.

Merge branch 'nd/diff-stat-with-summary'

2018-03-14T19:01:02Z

"git diff" and friends learned "--compact-summary" that shows the information usually given with the "--summary" option on the same line as the diffstat output of the "--stat" option (which saves vertical space and keeps info on a single path at the same place). * nd/diff-stat-with-summary: diff: add --compact-summary diff.c: refactor pprint_rename() to use strbuf

diff: add --compact-summary

2018-02-27T23:22:47Z

Certain information is currently shown with --summary, but when used in combination with --stat it's a bit hard to read since info of the same file is in two places (--stat and --summary). On top of that, commits that add or remove files double the number of display lines, which could be a lot if you add or remove a lot of files. --compact-summary embeds most of --summary back in --stat in the little space between the file name part and the graph line, e.g. with commit 0433d533f1: Documentation/merge-config.txt | 4 + builtin/merge.c | 2 + ...-pull-verify-signatures.sh (new +x) | 81 ++++++++++++++ t/t7612-merge-verify-signatures.sh | 45 ++++++++ 4 files changed, 132 insertions(+) It helps both condensing information and saving some text space. What's new in diffstat is: - A new 0644 file is shown as (new) - A new 0755 file is shown as (new +x) - A new symlink is shown as (new +l) - A deleted file is shown as (gone) - A mode change adding executable bit is shown as (mode +x) - A mode change removing it is shown as (mode -x) Note that --compact-summary does not contain all the information --summary provides. Rewrite percentage is not shown but it could be added later, like R50% or C20%. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

Merge branch 'sb/diff-blobfind-pickaxe'

2018-01-23T21:16:37Z

"diff" family of commands learned "--find-object=" option to limit the findings to changes that involve the named object. * sb/diff-blobfind-pickaxe: diff: use HAS_MULTI_BITS instead of counting bits manually diff: properly error out when combining multiple pickaxe options diffcore: add a pickaxe option to find a specific blob diff: introduce DIFF_PICKAXE_KINDS_MASK diff: migrate diff_flags.pickaxe_ignore_case to a pickaxe_opts bit diff.h: make pickaxe_opts an unsigned bit field

diffcore: add a pickaxe option to find a specific blob

2018-01-04T23:02:40Z

Sometimes users are given a hash of an object and they want to identify it further (ex.: Use verify-pack to find the largest blobs, but what are these? or [1]) One might be tempted to extend git-describe to also work with blobs, such that `git describe ` gives a description as ':'. This was implemented at [2]; as seen by the sheer number of responses (>110), it turns out this is tricky to get right. The hard part to get right is picking the correct 'commit-ish' as that could be the commit that (re-)introduced the blob or the blob that removed the blob; the blob could exist in different branches. Junio hinted at a different approach of solving this problem, which this patch implements. Teach the diff machinery another flag for restricting the information to what is shown. For example: $ ./git log --oneline --find-object=v2.0.0:Makefile b2feb64309 Revert the whole "ask curl-config" topic for now 47fbfded53 i18n: only extract comments marked with "TRANSLATORS:" we observe that the Makefile as shipped with 2.0 was appeared in v1.9.2-471-g47fbfded53 and in v2.0.0-rc1-5-gb2feb6430b. The reason why these commits both occur prior to v2.0.0 are evil merges that are not found using this new mechanism.

diff: introduce DIFF_PICKAXE_KINDS_MASK

2018-01-04T23:02:40Z

Currently the check whether to perform pickaxing is done via checking `diffopt->pickaxe`, which contains the command line argument that we want to pickaxe for. Soon we'll introduce a new type of pickaxing, that will not store anything in the `.pickaxe` field, so let's migrate the check to be dependent on pickaxe_opts. It is not enough to just replace the check for pickaxe by pickaxe_opts, because flags might be set, but pickaxing was not requested ('-i'). To cope with that, introduce a mask to check only for the bits indicating the modes of operation. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

diff: migrate diff_flags.pickaxe_ignore_case to a pickaxe_opts bit

2018-01-04T23:02:40Z

Currently flags for pickaxing are found in different places. Unify the flags into the `pickaxe_opts` field, which will contain any pickaxe related flags. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

diff.h: make pickaxe_opts an unsigned bit field

2018-01-04T23:02:40Z

This variable is used as a bit field[1], and as we are about to add more fields, indicate its usage as a bit field by making it unsigned.

diff: support anchoring line(s)

2017-11-28T01:40:04Z

Teach diff a new algorithm, one that attempts to prevent user-specified lines from appearing as a deletion or addition in the end result. The end user can use this by specifying "--anchored=" one or more times when using Git commands like "diff" and "show". Signed-off-by: Jonathan Tan Signed-off-by: Junio C Hamano

Merge branch 'bw/diff-opt-impl-to-bitfields'

2017-11-09T05:31:27Z

A single-word "unsigned flags" in the diff options is being split into a structure with many bitfields. * bw/diff-opt-impl-to-bitfields: diff: make struct diff_flags members lowercase diff: remove DIFF_OPT_CLR macro diff: remove DIFF_OPT_SET macro diff: remove DIFF_OPT_TST macro diff: remove touched flags diff: add flag to indicate textconv was set via cmdline diff: convert flags to be stored in bitfields add, reset: use DIFF_OPT_SET macro to set a diff flag
