2020-12-21diff-merges: do not imply -p for new optionsLibravatar Sergey Organov2-8/+13
Add 'combined_imply_patch' field and set it only for old --cc/-c options, then imply -p if this flag is set instead of implying -p whenever 'combined_merge' flag is set. We don't want new --diff-merge options to imply -p, to make it possible to enable output of diffs for merges independently from non-merge commits. At the same time we want to preserve behavior of old --c/-c/-m options and their interactions with --first-parent, to stay backward-compatible. This patch is first step in this direction: it separates old "--cc/-c imply -p" logic from the rest of the options.

2020-12-21diff-merges: implement new values for --diff-mergesLibravatar Sergey Organov1-3/+16
We first implement new options as exact synonyms for their original counterparts, to get all the infrastructure right, and keep functional improvements for later commits. The following values are implemented: --diff-merges= old equivalent first|first-parent = --first-parent (only format implications) sep|separate = -m comb|combined = -c dense| dense-combined = --cc Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-12-21diff-merges: make -m/-c/--cc explicitly mutually exclusiveLibravatar Sergey Organov1-0/+3
-c/--cc got precedence over -m only because of external logic where corresponding flags are checked before that for -m. This is too error-prone, so add code that explicitly makes these 3 options mutually exclusive, so that the last option specified on the command-line gets precedence.

2020-12-21diff-merges: refactor opt settings into separate functionsLibravatar Sergey Organov1-22/+41
To prepare introduction of new options some of which will be synonyms to existing options, let every option handling code just call corresponding function. Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-12-21diff-merges: get rid of now empty diff_merges_init_revs()Libravatar Sergey Organov3-7/+0
After getting rid of 'ignore_merges' field, the diff_merges_init_revs() function became empty. Get rid of it. Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-12-21diff-merges: group diff-merge flags next to each other inside 'rev_info'Libravatar Sergey Organov1-2/+3
The relevant flags were somewhat scattered over definition of 'struct rev_info'. Rearrange them to group them together. Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-12-21diff-merges: split 'ignore_merges' fieldLibravatar Sergey Organov3-26/+23
'ignore_merges' was 3-way field that served two distinct purposes that we now assign to 2 new independent flags: 'separate_merges', and 'explicit_diff_merges'. 'separate_merges' tells that we need to output diff format containing separate diff for every parent (as opposed to 'combine_merges'). 'explicit_diff_merges' tells that at least one of diff-merges options has been explicitly specified on the command line, so no defaults should apply.

2020-12-21diff-merges: fix -m to properly override -c/--ccLibravatar Sergey Organov2-2/+3
Logically, -m, -c, --cc specify 3 different formats for representing merge commits, yet -m doesn't in fact override -c or --cc, that makes no sense. Fix -m to properly override -c/--cc, and change the tests accordingly. Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-12-21diff-merges: revise revs->diff flag handlingLibravatar Sergey Organov1-3/+1
Do not set revs->diff when we encounter an option that needs it, as it'd be impossible to undo later. Besides, some other options than what we handle here set this flag as well, and we'd interfere with them trying to clear this flag later. Rather set revs->diff, if finally needed, in diff_merges_setup_revs(). As an additional bonus, this also makes our code shorter.

2020-12-21diff-merges: handle imply -p on -c/--cc logic for log.cLibravatar Sergey Organov2-4/+5
Move logic that handles implying -p on -c/--cc from log_setup_revisions_tweak() to diff_merges_setup_revs(), where it belongs. Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-12-21diff-merges: introduce revs->first_parent_merges flagLibravatar Sergey Organov3-2/+5
This new field allows us to separate format of diff for merges from 'first_parent_only' flag which primary purpose is limiting history traversal. This change further localizes diff format selection logic into the diff-merges.c file. Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2020-12-21diff-merges: new function diff_merges_set_dense_combined_if_unset()Libravatar Sergey Organov4-8/+24

2020-12-21diff-merges: new function diff_merges_suppress()Libravatar Sergey Organov4-4/+21
This function sets all the relevant flags to disabled state, so that no code that checks only one of them get it wrong. Then we call this new function everywhere where diff merges output suppression is needed. Signed-off-by: Sergey Organov <sorganov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2020-12-21diff-merges: move checks for first_parent_only out of the moduleLibravatar Sergey Organov3-9/+11
The checks for first_parent_only don't in fact belong to this module, as the primary purpose of this flag is history traversal limiting, so get it out of this module and rename the diff_merges_first_parent_defaults_to_enable() to diff_merges_default_to_enable() to match new semantics.
