Feature #80: D-Bus support - 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).

Bug fix #84: Root window not repainted sometimes on wallpaper change - 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().

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.

Bug fix #84: Root window not repainted sometimes on wallpaper change - 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().

Bug fix #84: Root window not repainted sometimes on wallpaper change - 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().

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).

Bug fix #84: Root window not repainted sometimes on wallpaper change - 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().
