Richard Grenville 35c9e44de2 Improvement: Try to reduce reg_ignore regenerations
- Try to reduce regenerations of reg_ignore. Highly experimental and
  could lead to very obscure bugs. More testing needed.

- Introduce to_paint in struct _win to keep track of whether this window
  was painted last time.

- Drop CAN_DO_USABLE support. Its usage looks pretty limited.

- Fix a bug that possibly causes rendering issues on frame width changes
  if frame_opacity is enabled.

- Detect other borders (instead of only top border) when determining
  frame opacity.

- Change the type of w->mode from int to an enumeration type.

- Ignore ShapeNotify if the window is not mapped, to avoid loss of
  w->border_size in some cases, which breaks the fading out process of
  shaped windows.

- Stop rendering a window if its picture is lost and it's unmapped, to
  avoid a series of X errors and possible rendering problems.

Richard Grenville 56e181309e Misc: Small adjustments
- Minor change of code in configure_win() for a slight performance boost
  in some cases.

- Discovered there are a lot of X errors that I basically cannot fix, caused by
  the asynchronous nature of Xlib...

- Correct the position of the timestamps in DEBUG_REPAINT. This might
  have negative effects for debugging X errors, though.

Richard Grenville 853d20ef56 Bug fix: Fading blocks in rare circumstances
- In very rare circumstances, poll() to the X connection returns 1 but
  no events are read out, causing XNextEvent() in the main loop to wait
  infinitely until another event comes, typically affecting fading
  process only, causing fading to appear somehow stopped. This commit
  adds a (possible) fix.

- Listen to Expose events of the X Composite overlay window if we are
  painting to it, to avoid making some parts of the screen blank when
  switching out of X screen in --paint-on-overlay mode.

- Drop "fade_fin" member of struct _win, because it's pretty useless.

- Drop unused "root" parameter of expose_root(), move get_time_ms() to
  compton.h, etc.

Richard Grenville 9b61999cae Merge branch 'master' into richardgv-dev
Merged the documentation changes. Program code unchanged.

Richard Grenville 40178702ef Improvement: Change clear_shadow implementation
- Implement clear_shadow with painting region limitation instead of
  calculation in shadow image, to make it work correctly on windows with
  rounded corners, requested by funeral1988. This might cause more load
  on CPU, but could mean less load for GPU. The original implementation
  is kept but commented out.

- Code cleanup.

Richard Grenville f83ed19e14 Bug fix #57: Fix incorrect handling of InputOnly windows
- Stop rendering InputOnly windows. In the past I've misunderstood the
  whole thing, I guess, sorry. Thanks to garfilth and funeral1988 for
  reporting and providing valuable information.

- Fix a possible segfault in DDEBUG_EVENTS.

- Add "dbe" as a configuration file option.

- Attempt to slightly reduce the rendering delay after VSync in non-DBE
  mode. I don't think, however, that this would be greatly helpful for
  the tearing issue.

Richard Grenville 66e615775b Bug fix #7: Correct a possible issue in VSync
- I realized I might have fundamentally misunderstood VSync. This commit
  tries to fix the possible problem, or at least move the tearing line
  close to the top of the screen.

- Software VSync is replaced by --sw-opti (software optimization), as
  I guess it isn't possible at all to do VSync without driver support.

- Add "vsync" and "sw-opti" as configuration file options.
2012-10-26 11:28:38 +08:00
Richard Grenville 049621bed7 Improvement: Add painting on overlay support
- Add support for painting on X Composite overlay window instead of root
  window (--paint-on-overlay). I intended to use this to fix the
  conflict between conky (own-window off) and compton, but it's
  unsuccessful. Will have to ask somebody to figure out how to solve
  this problem.

- Rename a few variables to avoid confusion.

- Slightly change how root window content (wallpaper) change is
  detected.

- Slightly improve window name detection in DEBUG_EVENTS.

Richard Grenville 5dd544d29d Improvement #7: Add double buffering
Add double buffering with X DBE extension in hope to get rid of the
tearing issue. Thanks to cairo-compmgr for providing hints. Could be
enabled with --dbe. Only very limited tests have been done, I don't know
if it actually solves the tearing issue. My estimation is it is harmful
for performance, but I found no clear evidence. Experimental, so no
configuration file option is available for it.

MONITOR_REPAINT is broken if --dbe is turned on, this is intended for
testing whether DBE is actually working.

Richard Grenville fe2146f1a5 Misc: Drop support for old versions of libXcomposite
Basically dropping support for HAS_NAME_PIXMAP = 0 because I don't think
there are many people using it, and I cannot maintain it. CAN_DO_USABLE
support is under evaluation.

Richard Grenville b78ab316fd Improvement: Stop painting on regions of higher windows
Sort of reverts cdf7db750d, but implements in a different way. (Well,
maybe the pre-cdf7db750d way is actually better, if I'm willing to
sacrifice some precious code reusability.) Basically, trading CPU for
GPU, in an attempt to solve farseerfc and ichi-no-eda's problems. Highly
experimental, could be revoked at any moment.
2012-10-21 20:49:34 +08:00
Richard Grenville 07e4420ab4 Improvement: Pregenerate alpha pictures
Pregenerate alpha pictures to save time when painting. Add --alpha-step
to control the step of alpha picture generation (the opacity difference
between two consecutively generated alpha pictures).
2012-10-13 19:11:25 +08:00
Richard Grenville 72ea4b5f47 Misc: Code clean-up
- Fix a memory leak in register_cm().

- Print a warning message if argument of --vsync is invalid.

- Known bug: compton will probably freeze X if another compositing
  window manager is running and --vsync opengl is enabled, with
  nvidia-drivers-304.51. Probably an issue on the driver. I could see no
  workaround.
2012-10-10 21:17:48 +08:00
Richard Grenville b59e592588 Feature: #7: VSync
- Add VSync feature. 3 possible VSync methods available: "sw" (software,
  not too reliable, but at least you have something to fallback to),
  "drm" (using DRM_IOCTL_WAIT_VBLANK, should work only on DRI drivers),
  "opengl" (using SGI_swap_control extension OpenGL, might work on more
  drivers than the DRM method). "sw" and "opengl" are briefly tested,
  "drm" received utterly no test (because I use the nVidia binary blob).
  They are enabled with "--vsync sw" / "--vsync drm" / "--vsync opengl".

- Add --refresh-rate to let user specify a refresh rate for software
  VSync, in case the automatic refresh rate detection does not work
  well.

- Seemingly the automatic refresh rate detection using X RandR in
  software VSync detects refresh rate incorrectly. Need further investigation.

- Fix a few bugs in fading timing.

- Add a workaround for client window detection on Fluxbox, as Fluxbox
  (incorrectly?) sets the override-redirect flag upon all frame
  windows.

- Software VSync adds dependency on librt (a part of glibc) for
  nanosecond-level timing functions, and libXrandr for automatic refresh
  rate detection; DRM VSync adds dependency on libdrm to use its drm.h,
  but does not link to libdrm; OpenGL VSync adds dependency on libGL.

- Print timing information on DEBUG_REPAINT.

Richard Grenville 1306b1591f Improvement: Support reading _NET_WM_OPACITY from client windows
- Some WMs don't respect Keith Packard's proposal of
  _NET_WM_WINDOW_OPACITY, and do not copy _NET_WM_OPACITY attribute of a
  client window to its frame windows, thus cause opacity set by
  non-override-redirect windows to have no effect. This commit adds
  support for reading _NET_WM_OPACITY from client windows if running
  with --detect-client-opacity. Thanks to pvanek for reporting.

- Change Makefile logic to determine options from 3 variables
  (NO_LIBCONFIG, NO_REGEX_PCRE, NO_REGEX_PCRE_JIT) instead of CFG to
  ensure compatibility when we add new options. CFG variable is no
  longer been respected.
2012-10-03 21:21:43 +08:00
Richard Grenville b8f3d22a32 Misc: #49: Add CMake support
Add CMakeLists.txt to support building with CMake, as @pvanek requests.
The old Makefile system and CPackConfig.cmake are still usable. (Of
course, make sure you don't overwrite them by executing cmake.) There
must be a bunch of bugs in CMakeLists.txt. :-) Let chjj decide which one
he will choose, here I keep both.

Richard Grenville ff50322b27 Misc: #49: Add CPack configuration
Add CPackConfig.cmake for generating binary packages (.tar.bz2, .deb,
.rpm) automatically. Pretty ugly, but mostly working.
CPackSourceConfig.cmake isn't ready yet.
2012-10-02 22:01:22 +08:00
Richard Grenville f95093358e Improvement: Change in client window lookup & wintype detection
- Revert to WM_STATE for client window lookup, as WM_CLASS is
  unreliable, either, but set the client window of an override-redirect
  window to itself.

- Conform to EWMH to make assumptions about window types when
  _NET_WM_WINDOW_TYPE is not available.

- Remove determine_wintype() and completely rely on client window for
  window type detection.

Richard Grenville 2f0417cd74 Feature: #27: Detect shaped windows and disable shadow on them
- Optionally detect shaped windows using X Shape extension and disable
  shadow on them with --shadow-ignore-shaped.

- Some windows are bounding-shaped just to support rounded corners, like
  Chromium windows (when system titlebar is disabled in its settings).
  Add --detect-rounded-corners to treat them as non-shaped windows (thus
  enable shadow on them). The algorithm I use is not perfect and wrong
  detection results are pretty possible to appear.

- Many windows don't use X Shape extensions to add shapes but use ARGB
  background instead. These windows could only be blacklisted with
  --shadow-blacklist.

- Rename a few functions. Code clean up.

Richard Grenville 8d7d6405b6 Improvement: Wait infinitely for events when idling
Wait infinitely for events when idling, instead of always calling
paint_preprocess(), to reduce CPU usage in the case. Thanks to valr for
help.
2012-09-29 22:53:57 +08:00
Richard Grenville 5a3dfbc064 Improvement: Split shadow_pict to shadow_pict & shadow_alpha_pict
Split w->shadow_pict to w->shadow_pict and w->shadow_alpha_pict, so that
the whole w->shadow_pict need not to be rebuild on shadow opacity
change. This greatly reduces CPU usage of compton when a window with
shadow is fading. (My test shows the CPU usage of compton process
dropped from 1.15% to 0.35% when constantly fading in and out a window.)
It uses a rather painful and slow method in shadow_picture() to get
around the limitation of PictStandardA8 to make colored shadows work. I
wonder if there's a better approach.

- Merge variables gsize and cgsize as they seemingly represent the same
  thing.

Richard Grenville 9139d038c2 Bug fix: #48: Compilation failure with old libconfig/libpcre
- Fix compilation failure with <libpcre-8.20 and <libconfig-1.4. Tested
  with libpcre-8.12 and libconfig-1.3.2, but not extensively tested.
  libconfig-1.3* probably has more limitations on configuration file
  syntax (enforces comma at the end of a setting?) and does not support
  @include.

- Make it possible to turn off PCRE and libconfig support using
  environment variable "CFG". Not well tested. CMake might provide a
  better solution.

Richard Grenville 69513d6231 Bug fix: Issue #47: Locale cause problems with float arguments

Richard Grenville 75ebe94bb6 Feature: --no-fading-openclose to partially simulate -F
-F hasn't being working for long. This commit adds a switch
--no-fading-openclose (and a configuration file option of the same name)
to simulate the behavior when only -F is enabled, which disables fading
when opening/closing windows, and makes -F an alias for -f.

Enable by using --mark-ovredir-focused.
2012-09-26 19:48:36 +08:00
Richard Grenville 606e2d7061 Misc: Code clean-up
- Change some members of options_t. Clean up wrongly replaced option
  names in comments. Rename "options" to "opts", to avoid breaking line
  width too much, and to minimize typing as it's so frequently used.
  :-)

- Let general options in commandline arguments override wintype-specific
  options in a configuration file, which could be a more natural
  behavior.

Richard Grenville 564e55e22c Feature: Wintype-specific options in configuration files
- Add support of window-type-specific options (fade, shadow, and
  opacity) in configuration file parsing. Syntax shown in
  compton.sample.conf.

- Replace wintype_name() with an array of window type names. Code
  clean-up.
2012-09-25 21:08:54 +08:00
Richard Grenville ee9e90efec Feature: Configuration file parsing
- Add support for parsing configuration files using libconfig.
  (Dependency on libconfig could be made optional once we get some
  better building system.) Few tests has been done, bugs to be expected.
  compton searches for a configuration file mostly according to the XDG
  standard. Firstly the configuration file requested by --config, then
  $XDG_CONFIG_HOME/compton.conf (~/.config/compton.conf, usually), then
  ~/.compton.conf, then compton.conf under $XDG_DATA_DIRS (often
  /etc/xdg/compton.conf). A sample configuration file is supplied as
  compton.sample.conf. Configuration file syntax may change in the
  future.  Commandline switches has higher priority than configuration
  file, except for --shadow-exclude. Use --config /dev/null to
  temporarily disable configuration file.

- Fix a bug that causes windows to disappear or be partially rendered on
  opacity changes.

- Fix a bug that causes some windows to ignore -i (inactive_opacity) and
  --inactive-dim, caused by the default window type change in
  a5d9955ca4.

Richard Grenville ce51d564d5 Misc: Fix two memory leaks
- Fix two small memory leaks. valgrind detects another memory leak

  couldn't fix that one.

- Use predefined atoms in Xatom.h to replace a few XInternAtom() calls.

Richard Grenville a5d9955ca4 Improvement: Change window type detection
- 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().
2012-09-22 20:59:26 +08:00
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.
2012-09-20 14:11:50 +08:00
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.

  used.

- Now compton paints windows from the lowest to the highest.  Warning:

  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().
2012-09-17 16:04:04 +08:00
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,
