- Fix OpenGL 3.0 compatibility by changing glFramebufferTexture() to
glFramebufferTexture2D(). Thanks to danfe for suggestion!
- Add notification about DocBook toolchina dependencies. Thanks to
danfe. (#121)
- Add --opacity-rule, which sets opacity based on conditions, as
requested by zabbal. (#113)
- Add a data field for each condition.
- Correct the FAQ link in README.md. Silly me.
- Code clean-up.
- Add multipass blur support. Note GLX Framebuffer support is required.
My benchmark shows multipass blur brings 5% performance boost for X
Render backend (3x3box). On GLX backend it brings 10% performance
boost for 5x5box but negatively affects performance for 3x3box. Thanks
to jrfonseca for advice. (#107)
- GLX backend: Cache blur texture for each window, for a 12% performance
boost.
- Add D-Bus fading control. Thanks to yulan6248 for testing. (#112)
- Fix FAQ link in README.md. Thanks to lorenzos for report. (#111)
- Correctly deinitialize VSync on on-the-fly VSync method switch.
- X Render backend: Normalize blur kernel.
- Code clean-up.
- Known issue: Linear corruption on border of a window may appear with X
Render multi-pass blur. Possible to fix but probably not worthwhile.
- GLX backend: Add --glx-use-copysubbuffermesa, to use
MESA_copy_sub_buffer to do partial screen update. Huge performance
boost on mesa drivers for partial screen updates, but does not work
for nvidia-drivers and may break VSync. Automagically overrides
--glx-copy-from-front.
- Add rect_is_fullscreen() to reuse code. Misc changes.
- Add on-the-fly VSync option modification via D-Bus, as requested by
kunitoki (#80). Expose parse_vsync(), create vsync_init() and
ensure_glx_context().
- Change default value of ps->drm_fd to -1.
- Update Makefile. Change the install/uninstall rules and add doc
installation, requested by hasufell in #85.
- Mark window not damaged in map_win(). It helps in reducing flickering
with inverted window color, but I'm not completely sure if it's safe.
- Avoid modifying w->invert_color when window is unmapped.
- Update documentation. Thanks to hasufell for pointing out.
- Add D-Bus support. Currently 7 methods are available: "reset" (same as
SIGUSR1), "list_win" (list the windows compton manages), "win_get"
(get a property of the window), "win_set" (set a property of the
window), "find_win" (find window based on client window / focus),
"opts_get" (get the value of a compton option), and "opts_set" (set
the value of a compton option), together with 4 signals: "win_added",
"win_destroyed", "win_mapped", "win_unmapped".
- D-Bus support depends on libdbus.
- As there are many items and my time is tight, no much tests are done.
Bugs to be expected.
- Create a new header file `common.h` that contains shared content.
- Fix some bugs in timeout handling.
- Update file headers in all source files.
- Re-enable --unredir-if-possible on multi-screen set-ups, as the user
could turn if off manually anyway.
- Check if the window is mapped in `repair_win()`.
- Add ps->track_atom_lst and its handlers, to prepare for the new
condition format.
- Known issue 1: "win_get", "win_set", "opts_get", "opts_set" support a
very limited number of targets only. New ones will be added gradually.
- Known issue 2: Accidental drop of D-Bus connection is not handled.
- Known issue 3: Introspection does not reveal all available methods,
because some methods have unpredictable prototypes. Still hesitating
about what to do...
- Known issue 4: Error handling is not finished yet. Compton does not
always reply with the correct error message (but it does print out the
correct error message, usually).
- Back to using select() for main loop. Thus we are not longer relying
on libevent.
- Add generic timeout system (untested) to prepare for D-Bus support.
- Drop troff man pages. Revise Makefile to improve documentation
building, fix double LDFLAGS inclusion, and re-add -lrt. This turns
asciidoc into a build time dependency.
- Change fading time calculation.
- Add --logpath and ostream_reopen() for debugging with -b.
- Drop unused lceil_ntimes() and other helper functions.
- Only very limited tests are done. Bugs to be expected.
- 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.
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.
- 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.
- 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.
