From 3521f10a978d5a82234eec2b24f92a4144014ec6 Mon Sep 17 00:00:00 2001 From: Richard Grenville Date: Tue, 8 Jan 2013 08:50:58 +0800 Subject: [PATCH] Improvement #74: Use libevent for main loop - Use libevent for main loop. I will explain the reasons in #56 later. The preferred libevent version is 2.x, yet 1.4.x should work as well. - As a result, compton now should build fine on *BSD. Thanks to DachiChang for the FreeBSD build issue report. - Another consequence is we now use microsecond-level timing all the way. Nanosecond-level code will be dropped soon. Start using long instead of unsigned long to represent time in milliseconds, as both can't hold the full epoch time in ms, anyway, and a signed type requires less care in subtraction. Wrap the epoch time in ms to 15 days. - Fix broken NO_VSYNC_DRM and NO_VSYNC_OPENGL compile-time options. - Use git revision number for versioning in Makefile, and other small improvements. - Reorganize struct _win. Drop unused w->damaged_sequence. w->damaged is turned to bool. - Add type and format to winprop_t, as preparation for the new condition format. - Add w->shadow_force and w->focus_force, to prepare for D-Bus support. - Rename wid_get_prop() to wid_get_prop_adv() with more options. Add wrapper function wid_get_prop(). - Add some extra helper functions, for D-Bus support later. - Make some functions return a bool value to indicate if it's successful. - Modify add_win(), use a static const structure to initialize the new struct _win. - Add some helper macros, like printf_err(f)(q). Make some errors fatal. - Rename some types, constants, and functions. Code clean-up. - Check for time disorder in paint_preprocess() when calculating fading steps. - Rename evpoll() to swopti_handle_timeout(), and partially rewrite it. - Make -h / --help legal. - Known issue: compton segfaults on FreeBSD with nvidia-drivers, unless NO_VSYNC_OPENGL is used. Will look into it later. Thamls to DachiChang for reporting. --- Makefile | 72 +++++-- README.md | 1 + src/compton.c | 513 +++++++++++++++++++++++++++++++------------------- src/compton.h | 314 ++++++++++++++++++++++-------- 4 files changed, 614 insertions(+), 286 deletions(-) diff --git a/Makefile b/Makefile index 10e6f179..ba477696 100644 --- a/Makefile +++ b/Makefile @@ -1,3 +1,6 @@ +# Use tab to indent recipe lines, spaces to indent other lines, otherwise +# GNU make may get unhappy. + CC ?= gcc PREFIX ?= /usr @@ -8,44 +11,79 @@ PACKAGES = x11 xcomposite xfixes xdamage xrender xext xrandr LIBS = -lm -lrt INCS = -# Parse configuration flags +# === Configuration flags === CFG = +# ==== libevent ==== +# Seemingly, libevent1 has no pkg-config file! +# FreeBSD 9.1 probably has issues handling --atleast-version in pkg-config. +ifeq "$(shell pkg-config --modversion --print-errors libevent)" "" + $(warning libevent-2.0 not found, assuming libevent-1.4.x.) + CFG += -DCONFIG_LIBEVENT_LEGACY + LIBS += -levent +else + # Using pkg-config for linking with libevent will result in linking with + # libevent.so instead of the smaller libevent_core.so.
