From 59482d00f33cd971691fc858689415a28f9c62a5 Mon Sep 17 00:00:00 2001 From: Hojun-Cho Date: Fri, 14 Aug 2026 22:46:42 +0900 Subject: [PATCH] fix(engine): compare logical transition state Avoid reading inactive Str storage when deciding whether to publish a redraw. Keep the focused engine suite compact by retaining one case for each page, navigation, and empty-result invariant. --- strans.c | 41 ++++++++++++-- tests/engine_test.c | 134 +++++++++++++------------------------------- 2 files changed, 77 insertions(+), 98 deletions(-) diff --git a/strans.c b/strans.c index 510b911..ca26959 100644 --- a/strans.c +++ b/strans.c @@ -835,6 +835,41 @@ transition(u32int ks, u32int mod, Str *com) return n; } +static int +samestate(Im *a, Search *as, Im *b, Search *bs) +{ + int i; + + if(a->l != b->l || scmp(&a->pre, &b->pre) != 0 || + scmp(&a->raw, &b->raw) != 0 || a->nkouho != b->nkouho || + a->sel != b->sel || as->lang != bs->lang || + scmp(&as->raw, &bs->raw) != 0 || scmp(&as->text, &bs->text) != 0) + return 0; + for(i = 0; i < a->nkouho; i++) + if(scmp(&a->kouho[i], &b->kouho[i]) != 0) + return 0; + return 1; +} + +static void +savestate(Im *p, Search *s) +{ + int i; + + memset(p, 0, sizeof *p); + memset(s, 0, sizeof *s); + p->l = im.l; + sappend(&p->pre, &im.pre); + sappend(&p->raw, &im.raw); + p->nkouho = im.nkouho; + p->sel = im.sel; + for(i = 0; i < im.nkouho; i++) + sappend(&p->kouho[i], &im.kouho[i]); + s->lang = search.lang; + sappend(&s->raw, &search.raw); + sappend(&s->text, &search.text); +} + static int keystrokeforce(u32int ks, u32int mod, Str *com, int force) { @@ -842,13 +877,11 @@ keystrokeforce(u32int ks, u32int mod, Str *com, int force) Search oldsearch; int eaten, ncom; - oldim = im; - oldsearch = search; + savestate(&oldim, &oldsearch); ncom = com->n; eaten = transition(ks, mod, com); if(force || eaten || com->n != ncom || - memcmp(&oldim, &im, sizeof im) != 0 || - memcmp(&oldsearch, &search, sizeof search) != 0) + !samestate(&oldim, &oldsearch, &im, &search)) redraw(); return eaten; } diff --git a/tests/engine_test.c b/tests/engine_test.c index f2f41da..02fa826 100644 --- a/tests/engine_test.c +++ b/tests/engine_test.c @@ -742,32 +742,20 @@ engine_candidate_page_metadata(struct ct *t) int shown; int local; } cases[] = { + { 1, 0, 0, 1, 0 }, { 9, 8, 0, 9, 8 }, { 10, 8, 0, 9, 8 }, { 10, 9, 9, 1, 0 }, { 18, 8, 0, 9, 8 }, { 18, 17, 9, 9, 8 }, + { 19, 0, 0, 9, 0 }, { 32, 8, 0, 9, 8 }, { 32, 17, 9, 9, 8 }, { 32, 26, 18, 9, 8 }, { 32, 31, 27, 5, 4 }, }; - Drawcmd dc; int i; - /* A clearing draw is the observable zero-candidate snapshot. */ - candidatebegin(1); - redraw(); - draindraw(nil); - setcandidates(0); - redraw(); - if(CT_CHECK(t, draindraw(&dc) > 0)){ - CT_EQ_INT(t, 0, dc.nkouho); - CT_EQ_INT(t, -1, dc.sel); - CT_EQ_INT(t, 0, dc.first); - CT_EQ_INT(t, 0, dc.total); - } - for(i = 0; i < nelem(cases); i++){ candidatebegin(cases[i].total); im.sel = cases[i].sel; @@ -779,19 +767,19 @@ engine_candidate_page_metadata(struct ct *t) void engine_candidate_page_snapshots(struct ct *t) { - static int totals[] = { 0, 1, 9, 10, 18, 19, 32 }; - int i, n; + Drawcmd dc; - for(i = 0; i < nelem(totals); i++){ - candidatebegin(totals[i]); - CT_EQ_INT(t, totals[i] == 0 ?
