- Let window type detection start with the client window if there's one,
in hope to enhance performance.
- Change get_wintype_prop() to fetch the property only once.
- Default to WINTYPE_UNKNOWN instead of WINTYPE_NORMAL if
_NET_WM_WINDOW_TYPE is missing.
- Fix a mistake in calc_opacity().
- Add some items to .gitignore.
- Fix a typo in usage().

- Add shadow blacklist feature, but a different implementation from
nicklan's. 5 matching modes (exact, starts-with, contains, wildcard,
PCRE) and 3 matching targets (window name, window class instance,
window general class). Not extensively tested, bugs to be expected.
It's slower for exact matching than nicklan's as it uses linear search
instead of hash table. Also, PCRE's JIT optimization may cause issues
on PaX kernels.
- Add dependency to libpcre. Could be made optional if we have a
graceful way to handle that in Makefile.
- Some matching functions are GNU extensions of glibc. So this version
may have troubles running on platforms not using glibc.
- Fix a bug that access freed memory blocks in set_fade_callcack() and
check_fade_fin(). valgrind found it out.
- Use WM_CLASS to detect client windows instead of WM_STATE. Some client
windows (like notification windows) have WM_CLASS but not WM_STATE.
- Mark the extents as damaged if shadow state changed in
determine_shadow().
- Rewrite wid_get_name(). Code clean-up.
- Two debugging options: DEBUG_WINDATA and DEBUG_WINMATCH.
- As the matching system is ready, it should be rather easy to add other
kinds of blacklists, like fading blacklist.

See chjj's comments on issue #39:
https://github.com/chjj/compton/issues/39#issuecomment-8533360
- Add a switch --mark-wmwin-focused that try to detect WM windows and
mark them active.
- Fix a bug that causes BadDrawable, etc. if a window is mapped then
immediately unmapped.
- Fix a bug in determine_evmask().
- Add a debug option DEBUG_CLIENTWIN.
- Force window repaint on window frame extent change.
- Code cleanup.

- Change fading mechanism for better modularity. Remove fade queue and
use members in struct _win to record fading data. In contrast to
previous commits, this one actually could make the program slower (but
very slightly, hardly noticeable if your CPU is anywhere close to AMD
K7). As this commit changes lots of things, bugs are to be expected.
- Currently -F does not do its job. -f actually equals -fF. (While in
the past -F equals nothing and -f is just -f.) A fix will be made
soon. I suppose it isn't hard.
- Add a preprocessor function paint_preprocess() and move all
preprocessing code in paint_all() to it.
- Add window flag support but currently unused.
- Add DamageNotify handling to ev_window().
- I'm considering removing HAS_NAME_WINDOW_PIXMAP = 0 support as I
couldn't see what it is good for. Nor do I know what CAN_DO_USABLE
does. Basically all my changes ignore these cases.

- Add ClientMessage detection to ev_name() and ev_window(), although we
don't actually handle the event.

- Defer shadow picture generation to minimize interactions with X,
hoping to boost performance.
- Fix a rendering issue caused by clip_changed in configure_win().
Remove clip_changed altogether.
- Split generation of shadow picture from calculating its geometry.
- Cache width/height including borders in struct _win as it's frequently
used.

- Now compton paints windows from the lowest to the highest. Warning:
I'm not completely certain that the change won't introduce unexpected
glitches. This commit may be revoked in the future.
- Remove w->border_clip since it's no longer needed.
- Correct a mistake in find_toplevel2(). (clang --analyze found it out.)
- Change "func_name()" prototypes to "func_name(void)". If I remember
correctly, "func_name()" means you are remaining silent about this
function's parameters instead of stating it has no parameter in ANSI
C.
- Add timestamps to error messages.
- Suppress error messages caused by free_damage().

- Change how w->alpha_pict is generated, in hope to boost performance,
slightly, and as a step to eventually move handling code of most resources
used when painting to paint_preprocess().
- Remove alpha_pict parameter of shadow_picture() as it's not
necessary.
- Let window opacity affect frame opacity.
- Rename some members of struct _win.
|
| |
|
|
|
|
|
|

- Add 4 helper free functions that free XserverRegion, Damage, Picture,
and Pixmap.
- Rename w->shadow to w->shadow_pict. Add a bool member w->shadow to
prepare for a future change.

- Look up the client window of a WM frame when it's mapped instead of when
it's created, for better reliability.
- Fix a warning when building.

I found compton segfaults sometimes when starting from .xinitrc.
Debugging reveals my conky window was just reparented to a fvwm's
frame window before compton picked up a FocusOut event on this conky
window that has just been destroyed in the event queue. find_win()
call in ev_focus_in/out() returned a NULL pointer. When it tried to
use the pointer segfault happens.
- Add extra check to ev_focus_in/out() to stop the segfault.
- Reset window event mask on window reparenting to a non-root window to
minimize wrong events.
- More abstraction for determining window event mask.

Use find_toplevel() to find out the WM frame of a client window. I
didn't noticed it beforehand. Fallback to the old method as compton does
not always get correct client windows.
- Clean up find_client_win() a bit. A BFS search algorithm could be more
optimal yet it requires a queue implementation.
|
| |
|
|
|
| |
Stop tracking focus changes unless either inactive_opacity or
inactive_dim is enabled, small performance boost in certain cases.
|
| |
|
|
|
|
|
|
|
| |
More information in the issue report.
- Let window opacity affect the opacity of its shadow and frames even if
-z is enabled.
- Check for the range of -o to eliminate potential segfault.

Take care of failure of XQueryTree() to prevent it from causing a
double-free crash. This usually happens when X is initializing and windows
are constantly changing.
|
| |
|
|
|
| |
More info in the issue description. This also fixes the problem for
--inactive-dim.
|
| |
|
|
|
|
|
| |
- Add a switch --inactive-dim that dims inactive windows.
- The window dimming feature is implemented in a pretty ugly way.
Improve it if possible.
|
| |
|
|
|
|
|
|
| |
- Change all #if DEBUG_XXX directives to #ifdef, thus making it
possible to directly enable debugging options with CFLAGS
(-DDEBUG_XXX).
- Print timestamp before event debugging messages.

I didn't read the documentation of getopt_long() carefully.
|
| |
|
|
|
|
|
|
|
|
| |
More details in the bug report.
- Rewritten much of the opacity calculation, code cleanup.
- Commandline switch --inactive_opacity_override to restore the old
behavior in which inactive_opacity has higher priority than
_NET_WM_OPACITY.
|
| |
|
|
|
|
|
| |
- Use getopt_long() instead of getopt() for argument parsing, making
long options possible.
- Add support of colored shadows with 3 commandline switches.

More descriptions on issue #36.
- Listens ShapeNotify event to get around the Chromium window painting
issues.
- Adds dependency on X Shape extension.
- Adds a few functions for convenience, so a bit code clean up.
- Better event debug support, adds restack_win() debug.
