- 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.
- Silence a FORTIFY_SOURCE warning. Thanks to @smlx for reporting.
- Add -O2 -D_FORTIFY_SOURCE=2 to default CFLAGS in Makefile.
- Use a cleaner way to resolve the writing-to-freed-memory issue
mentioned in last commit.
Add Asciidoc man pages. The old man page is still kept, and you need to
run "make docs" to generate the new man pages and a HTML version of it.
An Asciidoc man page for compton-trans is not added yet.
- Fix a memory leak in register_cm().
- Print a warning message if argument of --vsync is invalid.
- Known bug: compton will probably freeze X if another compositing
window manager is running and --vsync opengl is enabled, with
nvidia-drivers-304.51. Probably an issue on the driver. I could see no
workaround.
- Add VSync feature. 3 possible VSync methods available: "sw" (software,
not too reliable, but at least you have something to fallback to),
"drm" (using DRM_IOCTL_WAIT_VBLANK, should work only on DRI drivers),
"opengl" (using SGI_swap_control extension OpenGL, might work on more
drivers than the DRM method). "sw" and "opengl" are briefly tested,
"drm" received utterly no test (because I use the nVidia binary blob).
They are enabled with "--vsync sw" / "--vsync drm" / "--vsync opengl".
- Add --refresh-rate to let user specify a refresh rate for software
VSync, in case the automatic refresh rate detection does not work
well.
- Seemingly the automatic refresh rate detection using X RandR in
software VSync detects refresh rate incorrectly. Need further investigation.
- Fix a few bugs in fading timing.
- Add a workaround for client window detection on Fluxbox, as Fluxbox
(incorrectly?) sets the override-redirect flag upon all frame
windows.
- Software VSync adds dependency on librt (a part of glibc) for
nanosecond-level timing functions, and libXrandr for automatic refresh
rate detection; DRM VSync adds dependency on libdrm to use its drm.h,
but does not link to libdrm; OpenGL VSync adds dependency on libGL.
- Print timing information on DEBUG_REPAINT.
- Some WMs don't respect Keith Packard's proposal of
_NET_WM_WINDOW_OPACITY, and do not copy _NET_WM_OPACITY attribute of a
client window to its frame windows, thus cause opacity set by
non-override-redirect windows to have no effect. This commit adds
support for reading _NET_WM_OPACITY from client windows if running
with --detect-client-opacity. Thanks to pvanek for reporting.
- Change Makefile logic to determine options from 3 variables
(NO_LIBCONFIG, NO_REGEX_PCRE, NO_REGEX_PCRE_JIT) instead of CFG to
ensure compatibility when we add new options. CFG variable is no
longer been respected.
- Fix compilation failure with <libpcre-8.20 and <libconfig-1.4. Tested
with libpcre-8.12 and libconfig-1.3.2, but not extensively tested.
libconfig-1.3* probably has more limitations on configuration file
syntax (enforces comma at the end of a setting?) and does not support
@include.
- Make it possible to turn off PCRE and libconfig support using
environment variable "CFG". Not well tested. CMake might provide a
better solution.
- Add support for parsing configuration files using libconfig.
(Dependency on libconfig could be made optional once we get some
better building system.) Few tests has been done, bugs to be expected.
compton searches for a configuration file mostly according to the XDG
standard. Firstly the configuration file requested by --config, then
$XDG_CONFIG_HOME/compton.conf (~/.config/compton.conf, usually), then
~/.compton.conf, then compton.conf under $XDG_DATA_DIRS (often
/etc/xdg/compton.conf). A sample configuration file is supplied as
compton.sample.conf. Configuration file syntax may change in the
future. Commandline switches has higher priority than configuration
file, except for --shadow-exclude. Use --config /dev/null to
temporarily disable configuration file.
- Fix a bug that causes windows to disappear or be partially rendered on
opacity changes.
- Fix a bug that causes some windows to ignore -i (inactive_opacity) and
--inactive-dim, caused by the default window type change in
a5d9955ca4.
- Add shadow blacklist feature, but a different implementation from
nicklan's. 5 matching modes (exact, starts-with, contains, wildcard,
PCRE) and 3 matching targets (window name, window class instance,
window general class). Not extensively tested, bugs to be expected.
It's slower for exact matching than nicklan's as it uses linear search
instead of hash table. Also, PCRE's JIT optimization may cause issues
on PaX kernels.
- Add dependency to libpcre. Could be made optional if we have a
graceful way to handle that in Makefile.
- Some matching functions are GNU extensions of glibc. So this version
may have troubles running on platforms not using glibc.
- Fix a bug that access freed memory blocks in set_fade_callcack() and
check_fade_fin(). valgrind found it out.
- Use WM_CLASS to detect client windows instead of WM_STATE. Some client
windows (like notification windows) have WM_CLASS but not WM_STATE.
- Mark the extents as damaged if shadow state changed in
determine_shadow().
- Rewrite wid_get_name(). Code clean-up.
- Two debugging options: DEBUG_WINDATA and DEBUG_WINMATCH.
- As the matching system is ready, it should be rather easy to add other
kinds of blacklists, like fading blacklist.
More descriptions on issue #36.
- Listens ShapeNotify event to get around the Chromium window painting
issues.
- Adds dependency on X Shape extension.
- Adds a few functions for convenience, so a bit code clean up.
- Better event debug support, adds restack_win() debug.
