From 02468296c42cf3d0fd972596f4ebeebc8f37741a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ingo=20B=C3=BCrk?= Date: Wed, 14 Oct 2015 20:49:52 +0200 Subject: [PATCH] Introduce switch for the drawing backend This commit restores the old XCB drawing code paths while keeping the cairo drawing available via a compile-time switch (I3BAR_CAIRO). This is necessary as cairo currently has a bug that breaks i3bar for users without the RENDER extension, which might be the case, e.g., for VNC users. For more context, see #1989 and the discussions about its fix. Once the cairo fix is available in a stable release, i3 can depend on that version and remove the XCB drawing code paths. fixes #1989 --- i3bar/include/common.h | 2 +- i3bar/include/{cairo_util.h => draw_util.h} | 42 +++---- i3bar/include/outputs.h | 2 +- i3bar/src/{cairo_util.c => draw_util.c} | 74 ++++++++--- i3bar/src/xcb.c | 129 ++++++++++---------- libi3/font.c | 5 - 6 files changed, 142 insertions(+), 112 deletions(-) rename i3bar/include/{cairo_util.h => draw_util.h} (59%) rename i3bar/src/{cairo_util.c => draw_util.c} (66%) diff --git a/i3bar/include/common.h b/i3bar/include/common.h index 50d1c7b9..131412c1 100644 --- a/i3bar/include/common.h +++ b/i3bar/include/common.h @@ -80,4 +80,4 @@ TAILQ_HEAD(statusline_head, status_block) statusline_head; #include "config.h" #include "libi3.h" #include "parse_json_header.h" -#include "cairo_util.h" +#include "draw_util.h" diff --git a/i3bar/include/cairo_util.h b/i3bar/include/draw_util.h similarity index 59% rename from i3bar/include/cairo_util.h rename to i3bar/include/draw_util.h index fe2d06ff..9bac72ca 100644 --- a/i3bar/include/cairo_util.h +++ b/i3bar/include/draw_util.h @@ -3,13 +3,16 @@ * * © 2015 Ingo Bürk and contributors (see also: LICENSE) * - * cairo_util.h: Utility for operations using cairo. + * draw.h: Utility for drawing. * */ #pragma once +#ifdef I3BAR_CAIRO #include +#endif +#ifdef I3BAR_CAIRO /* We need to flush cairo surfaces twice to avoid an assertion bug.
