Richard Grenville 0d6724385e Feature: Issue #29: Alternative shadow blacklist implementation
- 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.

Richard Grenville 8724101c0a Bug fix: Detect and mark WM windows as active
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.

Richard Grenville 778a8b177c Improvement: Change fading mechanism
- 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.

Richard Grenville e7da88890d Bug fix: Issue #23, notify-osd not rendered
More details in the issue report.

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

Richard Grenville 1437e406c7 Improvement: Defer shadow picture generation
- 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.

Richard Grenville cdf7db750d Improvement: Change painting sequence
- 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().

Richard Grenville dfde67255f Improvement: Change generating process of alpha_pict, etc.
- 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.
2012-09-17 12:41:41 +08:00
Richard Grenville 64d53f6534 Misc: Clean up
- 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.

Richard Grenville 4293a4626a Bug fix: Issue #43, better client window lookup
More details on the issue report.

- 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.

Richard Grenville 271d894eae Bug fix: Segfault when meeting FocusIn/Out from destoryed windows
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.

Richard Grenville 18b3a96d0b Improvement: Use find_toplevel() to find WM frame
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.

Richard Grenville d0399313fc Improvement: Do not track focus changes unless necessary
Stop tracking focus changes unless either inactive_opacity or
inactive_dim is enabled, small performance boost in certain cases.

Richard Grenville 3abeb58690 Bug fix: Issue #40: -z does not work as expected
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.

Richard Grenville 6f079af2f0 Bug fix: Double free when XQueryTree() fails
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.

- Add a switch --inactive-dim that dims inactive windows.

- The window dimming feature is implemented in a pretty ugly way.
  Improve it if possible.

Richard Grenville f280750a03 Debug: Enhanced debugging capability

  possible to directly enable debugging options with CFLAGS
  (-DDEBUG_XXX).

- Print timestamp before event debugging messages.

More details in the bug report.

  _NET_WM_OPACITY.
