- 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).
