- 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)
- 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.
- 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 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 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 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).
