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().

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 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).

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.

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().

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().

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.

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).
