* Improvement: Enhance --glx-swap-methodRichard Grenville2013-04-261-5/+1
| | | | | - Enhance --glx-swap-method to support longer buffers ages (3-6), and automatic buffer age detection via GLX_EXT_buffer_age.
* Improvement: --glx-swap-method & --fade-excludeRichard Grenville2013-04-211-0/+12
| | | | | | | | | | | | | | | | - 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.
* Feature #4: Default active window opacityRichard Grenville2013-03-301-0/+18
| | | | | | - Add default active window opacity (--active-opacity). (#4) - Add win_focusin and win_focusout D-Bus signals.
* Improvement: --blur-background-exclude #98 & MESA_swap_control & othersRichard Grenville2013-03-231-0/+5
| | | | | | | | | | | | | | | - 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.
* Bug fix: GLX backend incompatibility with mesa & othersRichard Grenville2013-03-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.
* Improvement: ARGB window matching & Enable track_focus with D-BusRichard Grenville2013-03-101-0/+12
| | | | | | | - Add predefined matching target "argb" to match ARGB windows. - Make it possible to enable focus tracking on-the-fly with D-Bus method.
* Improvement: Change VSync mode with D-Bus & Makefile update & MiscRichard Grenville2013-01-311-0/+19
| | | | | | | | | | | | | | | | | | - 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.
* Feature #16: Advanced window matchingRichard Grenville2013-01-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.
* Bug fix #84: Root window not repainted sometimes on wallpaper changeRichard Grenville2013-01-241-15/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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().
* Feature #80: D-Bus supportRichard Grenville2013-01-191-0/+920
- 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).
