From 364c3d6f019a26e68f2bfb9594d6bc599a947be2 Mon Sep 17 00:00:00 2001 From: N-R-K Date: Wed, 1 Jun 2022 01:40:49 +0000 Subject: avoid doing dynamic allocation for bar buffers (#279) just use a static buffer since the size is constant and doesn't change. as opposed to using malloc, this also sets the buffer's initial memory region to 0 by default. also remove BAR_{L,R}_LEN from nsxiv.h, not needed after commit b4268fbf38d1f8433c73999466e116e68c7f81e7 --- nsxiv.h | 5 ----- window.c | 16 ++++++++-------- 2 files changed, 8 insertions(+), 13 deletions(-) diff --git a/nsxiv.h b/nsxiv.h index 55041bd..1b11cba 100644 --- a/nsxiv.h +++ b/nsxiv.h @@ -366,11 +366,6 @@ spawn_t spawn(const char*, char *const [], unsigned int); #include #endif -enum { - BAR_L_LEN = 512, - BAR_R_LEN = 64 -}; - enum { ATOM_WM_DELETE_WINDOW, ATOM__NET_WM_NAME, diff --git a/window.c b/window.c index 69c7b66..1e1ac59 100644 --- a/window.c +++ b/window.c @@ -106,11 +106,13 @@ void win_init(win_t *win) { win_env_t *e; const char *win_bg, *win_fg, *mrk_fg; + char *res_man; + XrmDatabase db; #if HAVE_LIBFONTS const char *bar_fg, *bar_bg, *f; + + static char lbuf[512 + 3], rbuf[64 + 3]; #endif - char *res_man; - XrmDatabase db; memset(win, 0, sizeof(win_t)); @@ -148,13 +150,11 @@ void win_init(win_t *win) f = win_res(db, RES_CLASS ".bar.font", DEFAULT_FONT); win_init_font(e, f); - win->bar.l.size = BAR_L_LEN; - win->bar.r.size = BAR_R_LEN; + win->bar.l.buf = lbuf; + win->bar.r.buf = rbuf; /* 3 padding bytes needed by utf8_decode */ - win->bar.l.buf = emalloc(win->bar.l.size + 3); - win->bar.l.buf[0] = '\0'; - win->bar.r.buf = emalloc(win->bar.r.size + 3); - win->bar.r.buf[0] = '\0'; + win->bar.l.size = sizeof(lbuf) - 3; + win->bar.r.size = sizeof(rbuf) - 3; win->bar.h = options->hide_bar ? 0 : barheight; win->bar.top = TOP_STATUSBAR; #endif /* HAVE_LIBFONTS */ -- cgit v1.2.3
