- Add stoppaint_force option, controlled via D-Bus, to stop painting
completely, which may look better than unredirecting the screen,
sometimes. (#41)
- Add x2, y2 matching targets.
- Update documentation.

|
|
|
|
|
|

- Add "redirected_force" to D-Bus opts_get to forcefully
redirect/unredirect windows.
- Add D-Bus method "repaint", to, namely, repaint the screen.

- Add --paint-exclude to prevent certain windows from being painted, for
debugging purposes.
- Add predefined matching target "x", "y", "width", "height", "widthb",
"heightb", "border_width", and "fullscreen".

- Add --shadow-exclude-reg, which excludes certain regions on the screen
to have shadows painted in. (#116)
- Adjust session initialization order. Now X root and screen info and
basic X extensions are available in configuration parsing step.

- 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 DEBUG_GLX_MARK, to add GL marks around functions with
glStringMarkerGREMEDY(), and mark frame termination with
glFrameTerminatorGREMEDY().
- Print output of `compton -h` to stdout. (#110)
- GLX backend: Strip out elements with factor 0 in GLSL blur code.
Thanks to jrfonseca for guides. (#107)

- Fix GL_TEXTURE_RECTANGLE support. Thanks to amonakov for guides.
(#107)
- Enhance --glx-copy-from-front to improve performance and make it work
with --glx-swap-method, copied from kwin patch. Thanks to bwat47 for
info. (#107)
- Add texture2Doffset() support in blur GLSL shader. Thanks to amonakov
for advice. No visible benefit here, though. (#107)

Pixmap as well.
- Update README.md and man page.

- Add a few predefined blur kernels, requested by jerri in #104.
- Add compton-convgen.py to generate blur kernels.

- Fix --resize-damage. I forgot to shrink the painting region back when
actually copying to destination.
- Include extra pixels around the blur texture to avoid some possible
small issues, if --resize-damage is positive.
- Known issue: Line artifacts may still appear with --dbe (X Render
backend) or --glx-swap-method (GLX backend). I doubt if there's way to
fix this without very inefficient mechanisms.
|
|

- Add --resize-damage to enlarge/shrink repaint region by a specific
number of pixels, used for solving the line corruption issue with
blur. Thanks to Nuck and jerri in #104 for reporting.
- Fix the memory leak of blur shader string.
|
|
|
|

Fix gcc compilation error about "initializer element is not constant".
|
|
|
|
|

- Enhance --glx-swap-method to support longer buffers ages (3-6), and
automatic buffer age detection via GLX_EXT_buffer_age.
|
|
|
|
|
|
|
|
|
|

- Add blur convolution kernel customization, --blur-kern. The format is
a bit tricky so be sure to read the description in `compton -h`. Not
much tests received.
- GLX backend: Tolerate missing GLSL uniforms for strangely shaped
convolution kernel.
- Fix a memory leak that blur-background blacklist is not freed.
|

- GLX backend: Add --glx-swap-method, to reduce painting region if the
driver uses exchange or copy buffer swaps. Untested.
- Add --fade-exclude, to disable fading on specific windows based on
some conditions. Untested.
- Expose GLX backend options through configuration file. Add fetching of
GLX backend options through D-Bus.
- Use NULL pointer instead of element count to delimit string arrays in
parse_vsync()/parse_backend()/parse_glx_swap_method().
- Add documentation about "wintypes" section in configuration file.

- GLX backend: Fix broken dim and blur with --glx-no-stencil when
dealing with shaped windows.
- GLX backend: Cache region contents and do a local region intersection
instead of using XFixesIntersectRegion(). Drastic reduction in CPU
usage for --glx-no-stencil. Now --glx-no-stencil substantially
outperforms (~15%) normal mode.
- Use macros to reuse paint-in-region code in opengl.c . Add new type
"reg_data_t" to store XserverRegion cache.

- Cache region contents in is_region_empty(), mostly useful only for GLX
backend to save one roundtrip to X.
- GLX backend: Add --glx-no-rebind-pixmap, which prevents rebinding of
GLX texture to pixmap on content change. It doesn't work on some
drivers, but it saves some CPU on those where it does.
- Wrap XFree() with a new function cxfree() since its man page claims
NULL pointers are not acceptable (although in fact it does...).
- Use macro to save some code in get_cfg(). Code clean-up.
|
|

- Add workarounds for missing GL_TEXTURE_RECTANGLE and PictOpDifference
definitions in broken GL headers / old X Composite headers.

- GLX backend: Fix broken --inactive-dim.
- GLX backend: Fix bugs when inverting colors of windows. Thanks to
madsy and neure for help.
- GLX backend: Lift `glx_no_stencil` restriction from glx_init_blur().
It still probably won't work, but the user can try.
- XRender backend: Use XRenderFillRectangles() instead of
XRenderComposite() to do dimming.

- Add --blur-background-exclude. (#98)
- Add `opengl-mswc` VSync, which uses MESA_swap_control instead of
SGI_swap_control. I don't expect it to perform better than
SGI_swap_control, though.
- Update CMakeLists.txt .
- Add a few targets for D-Bus `win_get`. Misc changes.
- Known issue: Apparently I've forgotten implementing --inactive-dim on
GLX backend... Silly me.

- Fix a bug that ConfigureNotify placing a window in bottom
(ConfigureNotify with .new_above == 0) is not correctly handled,
introduced in 1a88e3d0c5.

- 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.
|
|
|
|
|
|
|
|
| |
- GLX backend: Add blur background support using a GLSL shader. Only
tested with nvidia-drivers-313.26. Known to cause quite some decrease
in performance (~10%?).
- Detach shaders in glx_create_program(). Misc changes.

- GLX backend: Add --glx-copy-front, which copies all unmodified regions
from front buffer to back buffer instead of redrawing the whole
screen. Unfortunately, probably because glCopyPixels() isn't usually
well-optimized on graphic cards, this option appears very unstable in
its effect: Over 20% boost in performance when only 1/4 of the screen
is modified, but 10% decrease when the whole screen is. Thus, not
enabled by default.
- GLX backend: Add glx_blur_dst(), to prepare for the background blur
feature. It currently is capable to modify background in the desired
way, but the core blur shader is absent. glConvolution2D() seemingly
relies entirely on CPU and has horrifying performance. I've hesitating
about whether I should use ARB assembly language or GLSL for the
shader.
- GLX backend: Invert y-axis GL matrix. It's upside-down previously
because that's what dcompmgr uses. Seemingly a "normal" y-axis is
required for glCopyPixels() to operate correctly.
- GLX backend: Fix some GLX_TEXTURE_RECTANGLE compatibility issues.
Still, not actually tested.
- Add benchmark mode (--benchmark & --benchmark-wid).
- Misc changes.

|
|
|

- GLX backend: Use GL_SCISSOR_TEST instead of STENCIL_TEST if there's
only one rectangle in glx_set_clip(). Profiling with gDebugger shows a
10% performance improvement.
- Add .desktop installation rules. (#97)

- GLX backend: Fix a bug that ARGB windows / shadows are rendered too
dark. Thanks to derhass in FreeNode/##opengl for help.
- GLX backend: Fix a problem that during window resize the content looks
jittering, by letting compton fetch pixmap sizes with XGetGeometry()
instead of relying on window width/height, which could be inaccurate
during window resize. Negative effect on performance. Thanks to M4he
for reporting. (#7)
- Add .desktop file. Thanks to quequotion for providing it. (#97)
- Avoid checking presence of window pixmap, because they may not exist
with very old X Composite implementations.
- Add workaround for a strange window restack issue when compton
receieves a ConfigureNotify with non-existent new above window.
- Add debugging function hexdump(). Extra sanity checks on various
places.

- GLX backend: Fix a bug that window content does not get updated on
VirtualBox, by rebinding texture when window content changes. This may
have a negative effect on performance.
- GLX backend: Add --glx-no-stencil to restore the old clipping method,
just in case.
- GLX backend: Apply stricter checks on texture-pixmap binding.
- GLX backend: Fix a bug that glx_set_clip() behaves incorrectly when
None is passed in.
- GLX backend: Use glEnable()/glDisable() to toggle stencil tests, in
hope to increase performance.
- Move window pixmap/picture fetching to win_paint_win(), in hope to
increase performance.
- Intersect shadow painting region with its bounding rectangle, in hope
to increase performance.

- Fix a bug that glx_bind_pixmap() doesn't work with mesa drivers.
Thanks to Janhouse and mkraemer for reporting. (#7)
- Use stencil buffer to attempt to eliminate potential double-paint
issue in glx_render(). X Fixes doesn't guarantee the rectangles in a
region do not overlap, and this may cause some regions to be painted
twice, which would be a problem if we are painting transparent things.
Now the target window must have a stencil buffer. Compiz uses its own
region implementation to deal with this, but as a lightweight
compositor we can't really do the same. It may have a positive or
negative effort over performance. Callgrind result indicates basically
no change in performance, but this may or may not be true.
- Correctly distinguish GL extensions and GLX extensions. Sorry. :-D
- Handle screen size. Thanks to tsmithe for reporting. (#7)
- Rename OpenGL backend to GLX backend, because, we might have a EGL
backend someday.
- Add configuration file option `backend` to specify backend. Add
`backend` to D-Bus `opts_get`.
- Add OpenGL shader compilation code, but currently unused.
- Minor adjustments.
- Known issue: Window content doesn't get updated in VirtualBox,
probably because its OpenGL implementation requires constant rebinding
of texture. But that's really slow...
- Known issue: Blur feature is still unimplemented in GLX backend.

- Add experimental OpenGL backend (--opengl). --blur-background is
currently not possible with this backend, because I'm still trying to
find a proper way to do blur with OpenGL. Flipping backend on-the-fly
is really hard, so it isn't supported right now. No configuration file
option exists to enable this, because it isn't stable enough.
- Add `opengl-swc` VSync method that uses SGI_swap_control to control
buffer swap, with OpenGL backend. (#7)
- Fix a potential read-from-freed-memory issue in paint_all().
- Correctly reattach GLX context after fork.
- Dump error text in error(). Add GLX error code handling.
- Code clean-up.
- Known issues: Region operations take a lot of time in glx_render().
I'm hesitating about what to do.

- Create OpenGL context only after initializing overlay, which fixes a
bug that --paint-on-overlay does not work with OpenGL VSync. Thanks to
tsmithe for reporting. (#7)

- Make it possible to enable focus tracking on-the-fly with D-Bus
method.

- #91: Use pkg-config to find drm.h to avoid issues on FreeBSD. Thanks
to hun7err for pointing out and providing patch.
- #89: Add default shadow exclusion rule for notify-osd. Thanks to
DanielRS.
- Check for abundant positional arguments.
- Use paint target window (root window / overlay window) instead of
ps->reg_win to create GLXContext. (May have negative effects on OpenGL
VSync.) Add new OpenGL helpers functions, to prepare for the new
OpenGL backend.
- Dump more info of a PropertyNotify with DEBUG_EVENTS.

- 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 "vsync-oml" VSync method, using GLX_OML_sync_control. Untested,
because it's not supported by my driver.
- Unredirect ps->reg_win, because DRI wiki says it's related to the
behavior of OpenGL VSync extensions.
- Add glFlush() and glXWaitX() calls, in hope they are slightly helpful
for VSync.
- Change a few functions to make error handling more graceful. Make some
errors fatal. Code clean-up.
- Add unused function make_text_prop().

- Try to improve the performance of color inversion by applying clipping
region during color inversion. (#75)
- Validate pixmap on window unmap/destruction. Probably slightly helpful
for #52.
- Change the design of unmap_win() and destroy_win(), a bit.
- Add warning message to help messages about features disabled at
compile time, instead of dropping their description completely. (#85)
- Silence some warnings. Code clean-up.

- Add advanced window matching system, capable of matching against
arbitrary window properties as well as a series of internal
properties, with 4 additional operators (>, <, >=, <=) useful for
integer targets, and support of logical operators. The old matching
system is removed, but compatibility with the format is retained.
- As the new matching system is pretty complicated, and I have no past
experience in writing a parser, it's pretty possible that bugs are
present. It also has inferior performance, but I hope it doesn't
matter on modern CPUs.
- It's possible to disable matching system at compile time with NO_C2=1
now.
- Add ps->o.config_file to track which config file we have actually
read. Queryable via D-Bus.
- Parse -d in first pass in get_cfg() as c2 needs to query X to get
atoms during condition parsing.
- Fix a bug in wid_get_prop_adv() that 0 == rformat is not handled
correctly.
- Fix incompatibility with FreeBSD sed in dbus-examples/cdbus-driver.sh
.
- Add recipe to generate .clang_complete in Makefile, used by Vim
clang_complete plugin.
- Add DEBUG_C2 for debugging condition string parsing. DEBUG_WINMATCH is
still used for match debugging.
- Rename win_on_wdata_change() to win_on_factor_change().
- Extra malloc() failure checks. Add const to matching cache members in
session_t. Code clean-up. Documentation update.

- Fix a bug that root window is not repainted on wallpaper change unless
an Expose X event is received. Seemingly, if there's no mapped window
on a screen, X will not send an Expose event when the wallpaper
changes. Thanks to baskerville for reporting.
- Fix a X Pixmap leak when there's no existing wallpaper pixmap found.
- Fix a bug in mstrncpy() that null character is not added to the end of
the copied string.
- Make VSYNC_STRS public, for use in src/dbus.c. Adjust the type of
WINTYPES array. Add NUM_VSYNC.
- Add more targets for various D-Bus methods. Add "bad_target" D-Bus
error. Improve error handling. Add more helper functions to append
arguments to a D-Bus message. Add Introspect method to D-Bus
introspection reply.
- Add public declarations of things in the new condition format code to
common.h. Move definitions of some inline functions from compton.h to
common.h. Make some functions public. Move wid_get_prop_adv() to
compton.c. The primary code files of the new format src/c2.{c,h} will
be published when ready.
- Add support for dumping version string in Makefile (make version), to
make snapshot generation easier.
- Add repeated inclusion protection to common.h.
- Update documentation.
- Use gsed instead of sed in dbus-examples/cdbus-driver.sh if possible,
as some BSD systems does not come with GNU sed by default. Thanks to
DaChiChang for reporting.
- Code clean-up. Small type changes in register_cm() to silence
warnings. Quit on failure in parse_vsync(). Apply stricter checks in
force_repaint().

- 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).

- Fix a small bug that breaks --invert-color-include if no other
blacklists are present. Thanks to MaskRay and xiaq for reporting.
- Disable --unredir-if-possible for multi-screen setups.
- Fix a bug that causes --no-fading-openclose to have no effect in some
cases. Add w->in_openclose to keep track of window open/close state.
