Richard Grenville 2e6fb0203d Improvement: --blur-kern
- Add blur convolution kernel customization, --blur-kern. The format is
  a bit tricky so be sure to read the description in `compton -h`. Not
  much tests received.

- GLX backend: Tolerate missing GLSL uniforms for strangely shaped
  convolution kernel.

- Fix a memory leak that blur-background blacklist is not freed.

Richard Grenville 4a4f857cc2 Misc: Fix wrong description & DEBUG_GLX_ERR
- Fix description of "opengl" VSync.

- Add DEBUG_GLX_ERR to check for OpenGL errors.

- Update man page.
2013-04-25 09:27:14 +08:00
Richard Grenville 85e7d18803 Improvement: --glx-swap-method & --fade-exclude
- GLX backend: Add --glx-swap-method, to reduce painting region if the
  driver uses exchange or copy buffer swaps. Untested.

- Add --fade-exclude, to disable fading on specific windows based on
  some conditions. Untested.

- Expose GLX backend options through configuration file. Add fetching of
  GLX backend options through D-Bus.

- Use NULL pointer instead of element count to delimit string arrays in
  parse_vsync()/parse_backend()/parse_glx_swap_method().

- Add documentation about "wintypes" section in configuration file.

Richard Grenville a053c0ac64 Bug fix: GLX: Fix dim and blur with --glx-no-stencil
- GLX backend: Fix broken dim and blur with --glx-no-stencil when
  dealing with shaped windows.

- GLX backend: Cache region contents and do a local region intersection
  instead of using XFixesIntersectRegion(). Drastic reduction in CPU
  usage for --glx-no-stencil. Now --glx-no-stencil substantially
  outperforms (~15%) normal mode.

- Use macros to reuse paint-in-region code in opengl.c . Add new type
  "reg_data_t" to store XserverRegion cache.
2013-04-06 20:21:38 +08:00
Richard Grenville e3a15d5f94 Improvement: GLX: Cache region contents & --glx-no-rebind-pixmap
- Cache region contents in is_region_empty(), mostly useful only for GLX
  backend to save one roundtrip to X.

- GLX backend: Add --glx-no-rebind-pixmap, which prevents rebinding of
  GLX texture to pixmap on content change. It doesn't work on some
  drivers, but it saves some CPU on those where it does.

- Wrap XFree() with a new function cxfree() since its man page claims
  NULL pointers are not acceptable (although in fact it does...).

- Use macro to save some code in get_cfg(). Code clean-up.
2013-04-05 21:05:19 +08:00
Richard Grenville 6ef23e066f Misc: Workaround for some missing definitions
- Add workarounds for missing GL_TEXTURE_RECTANGLE and PictOpDifference
  definitions in broken GL headers / old X Composite headers.

Richard Grenville dfd4dd1122 Feature #4: Default active window opacity
- Add default active window opacity (--active-opacity). (#4)

Richard Grenville 9e607b2543 Bug fix: GLX: Fix --inactive-dim & fix color inversion
- GLX backend: Fix broken --inactive-dim.

- GLX backend: Fix bugs when inverting colors of windows. Thanks to
  madsy and neure for help.

- GLX backend: Lift `glx_no_stencil` restriction from glx_init_blur().
  It still probably won't work, but the user can try.

- XRender backend: Use XRenderFillRectangles() instead of
  XRenderComposite() to do dimming.
2013-03-25 11:36:39 +08:00
Richard Grenville 75912d23f3 Improvement: --blur-background-exclude #98 & MESA_swap_control & others
- Add --blur-background-exclude. (#98)

- Add `opengl-mswc` VSync, which uses MESA_swap_control instead of
  SGI_swap_control. I don't expect it to perform better than
  SGI_swap_control, though.

- Update CMakeLists.txt .

- Add a few targets for D-Bus `win_get`. Misc changes.

- Known issue: Apparently I've forgotten implementing --inactive-dim on
  GLX backend... Silly me.
2013-03-23 22:06:41 +08:00
Richard Grenville 65cda415dd Bug fix: Incorrect handling when a window is placed on bottom
- Fix a bug that ConfigureNotify placing a window in bottom
  (ConfigureNotify with .new_above == 0) is not correctly handled,
  introduced in 1a88e3d0c5.
2013-03-22 16:44:03 +08:00
Richard Grenville 4b734c1fa1 Improvement: --glx-use-copysubbuffermesa
- GLX backend: Add --glx-use-copysubbuffermesa, to use
  MESA_copy_sub_buffer to do partial screen update. Huge performance
  boost on mesa drivers for partial screen updates, but does not work
  for nvidia-drivers and may break VSync. Automagically overrides
  --glx-copy-from-front.

- Add rect_is_fullscreen() to reuse code. Misc changes.
2013-03-21 13:05:56 +08:00
Richard Grenville 8208ec6dc8 Feature #69: GLX: Blur background
- GLX backend: Add blur background support using a GLSL shader. Only
  tested with nvidia-drivers-313.26. Known to cause quite some decrease
  in performance (~10%?).

- Detach shaders in glx_create_program(). Misc changes.
2013-03-20 17:29:45 +08:00
Richard Grenville 725bc40a65 Improvement: --glx-copy-from-front & benchmark mode
- GLX backend: Add --glx-copy-front, which copies all unmodified regions
  from front buffer to back buffer instead of redrawing the whole
  screen. Unfortunately, probably because glCopyPixels() isn't usually
  well-optimized on graphic cards, this option appears very unstable in
  its effect: Over 20% boost in performance when only 1/4 of the screen
  is modified, but 10% decrease when the whole screen is. Thus, not
  enabled by default.

- GLX backend: Add glx_blur_dst(), to prepare for the background blur
  feature. It currently is capable to modify background in the desired
  way, but the core blur shader is absent. glConvolution2D() seemingly
  relies entirely on CPU and has horrifying performance. I've hesitating
  about whether I should use ARB assembly language or GLSL for the
  shader.

- GLX backend: Invert y-axis GL matrix. It's upside-down previously
  because that's what dcompmgr uses. Seemingly a "normal" y-axis is
  required for glCopyPixels() to operate correctly.

- GLX backend: Fix some GLX_TEXTURE_RECTANGLE compatibility issues.
  Still, not actually tested.

- Add benchmark mode (--benchmark & --benchmark-wid).

- Misc changes.
2013-03-19 20:58:55 +08:00
Richard Grenville a41f05ea92 Improvement: GLX: Use SCISSOR_TEST instead of STENCIL_TEST when possible
- GLX backend: Use GL_SCISSOR_TEST instead of STENCIL_TEST if there's
  only one rectangle in glx_set_clip(). Profiling with gDebugger shows a
  10% performance improvement.

- Add .desktop installation rules. (#97)
2013-03-18 19:01:18 +08:00
Richard Grenville 1a88e3d0c5 Bug fix: GLX: ARGB texture too dark & Jitter when resize & others
- GLX backend: Fix a bug that ARGB windows / shadows are rendered too
  dark. Thanks to derhass in FreeNode/##opengl for help.

- GLX backend: Fix a problem that during window resize the content looks
  jittering, by letting compton fetch pixmap sizes with XGetGeometry()
  instead of relying on window width/height, which could be inaccurate
  during window resize. Negative effect on performance. Thanks to M4he
  for reporting. (#7)

- Add .desktop file. Thanks to quequotion for providing it. (#97)

- Avoid checking presence of window pixmap, because they may not exist
  with very old X Composite implementations.

- Add workaround for a strange window restack issue when compton
  receieves a ConfigureNotify with non-existent new above window.

- Add debugging function hexdump(). Extra sanity checks on various
  places.
2013-03-18 13:29:14 +08:00
Richard Grenville b6a99334ce Bug fix: GLX backend incompatibility with VirtualBox & others
- GLX backend: Fix a bug that window content does not get updated on
  VirtualBox, by rebinding texture when window content changes. This may
  have a negative effect on performance.

- GLX backend: Add --glx-no-stencil to restore the old clipping method,
  just in case.

- GLX backend: Apply stricter checks on texture-pixmap binding.

- GLX backend: Fix a bug that glx_set_clip() behaves incorrectly when
  None is passed in.

- GLX backend: Use glEnable()/glDisable() to toggle stencil tests, in
  hope to increase performance.

- Move window pixmap/picture fetching to win_paint_win(), in hope to
  increase performance.

- Intersect shadow painting region with its bounding rectangle, in hope
  to increase performance.
2013-03-17 12:14:00 +08:00
Richard Grenville 66be1f2fe1 Bug fix: GLX backend incompatibility with mesa & others
- Fix a bug that glx_bind_pixmap() doesn't work with mesa drivers.
  Thanks to Janhouse and mkraemer for reporting. (#7)

- Use stencil buffer to attempt to eliminate potential double-paint
  issue in glx_render(). X Fixes doesn't guarantee the rectangles in a
  region do not overlap, and this may cause some regions to be painted
  twice, which would be a problem if we are painting transparent things.
  Now the target window must have a stencil buffer. Compiz uses its own
  region implementation to deal with this, but as a lightweight
  compositor we can't really do the same. It may have a positive or
  negative effort over performance. Callgrind result indicates basically
  no change in performance, but this may or may not be true.

- Correctly distinguish GL extensions and GLX extensions. Sorry. :-D

- Handle screen size. Thanks to tsmithe for reporting. (#7)

- Rename OpenGL backend to GLX backend, because, we might have a EGL
  backend someday.

- Add configuration file option `backend` to specify backend. Add
  `backend` to D-Bus `opts_get`.

- Add OpenGL shader compilation code, but currently unused.

- Minor adjustments.

- Known issue: Window content doesn't get updated in VirtualBox,
  probably because its OpenGL implementation requires constant rebinding
  of texture. But that's really slow...

- Known issue: Blur feature is still unimplemented in GLX backend.
2013-03-16 22:54:43 +08:00
Richard Grenville 8ffcf1c1e8 Feature: OpenGL backend
- Add experimental OpenGL backend (--opengl). --blur-background is
  currently not possible with this backend, because I'm still trying to
  find a proper way to do blur with OpenGL. Flipping backend on-the-fly
  is really hard, so it isn't supported right now. No configuration file
  option exists to enable this, because it isn't stable enough.

- Add `opengl-swc` VSync method that uses SGI_swap_control to control
  buffer swap, with OpenGL backend. (#7)

- Fix a potential read-from-freed-memory issue in paint_all().

- Correctly reattach GLX context after fork.

- Dump error text in error(). Add GLX error code handling.

- Code clean-up.

- Known issues: Region operations take a lot of time in glx_render().
  I'm hesitating about what to do.

Richard Grenville b3652f6746 Bug fix #93: Assertion failure when window reparented
- Fix an assertion failure that occurs when a window is reparented to
  the root window then immediately to another window. Thanks to smlx for
  reporting.

- Add extra debugging info for ReparentNotify.

Richard Grenville e3eca7ac61 Bug fix #91: Using pkg-config to find drm.h & OpenGL changes
- #91: Use pkg-config to find drm.h to avoid issues on FreeBSD. Thanks
  to hun7err for pointing out and providing patch.

- #89: Add default shadow exclusion rule for notify-osd. Thanks to
  DanielRS.

- Check for abundant positional arguments.

- Use paint target window (root window / overlay window) instead of
  ps->reg_win to create GLXContext. (May have negative effects on OpenGL
  VSync.) Add new OpenGL helpers functions, to prepare for the new
  OpenGL backend.

- Dump more info of a PropertyNotify with DEBUG_EVENTS.

Richard Grenville 218250546e Misc #86: Compatibility with BSD install
- Make Makefile compatible with BSD install, by dropping -D.

- Make CFG independent in Makefile, to allow people to specify CFLAGS
  as a parameter to make.

- Correct location of .clang_complete.
2013-02-05 16:59:36 +08:00
Richard Grenville 8e34736c19 Improvement: Change VSync mode with D-Bus & Makefile update & Misc
- Add on-the-fly VSync option modification via D-Bus, as requested by
  kunitoki (#80). Expose parse_vsync(), create vsync_init() and
  ensure_glx_context().

- Change default value of ps->drm_fd to -1.

- Update Makefile. Change the install/uninstall rules and add doc
  installation, requested by hasufell in #85.

- Mark window not damaged in map_win(). It helps in reducing flickering
  with inverted window color, but I'm not completely sure if it's safe.

- Avoid modifying w->invert_color when window is unmapped.

- Update documentation. Thanks to hasufell for pointing out.
2013-01-31 22:56:54 +08:00
Richard Grenville 1b5273c819 Improvement #7: Add GLX_OML_sync_control VSync support
- Add "vsync-oml" VSync method, using GLX_OML_sync_control. Untested,
  because it's not supported by my driver.

- Unredirect ps->reg_win, because DRI wiki says it's related to the
  behavior of OpenGL VSync extensions.

- Add glFlush() and glXWaitX() calls, in hope they are slightly helpful
  for VSync.

- Change a few functions to make error handling more graceful. Make some
  errors fatal. Code clean-up.

- Add unused function make_text_prop().
2013-01-30 13:41:08 +08:00
Richard Grenville 42e17cb4e9 Improvement: Improve color inversion performance & Validate pixmap
- Try to improve the performance of color inversion by applying clipping
  region during color inversion. (#75)

- Validate pixmap on window unmap/destruction. Probably slightly helpful
  for #52.

- Change the design of unmap_win() and destroy_win(), a bit.

- Add warning message to help messages about features disabled at
  compile time, instead of dropping their description completely. (#85)

- Silence some warnings. Code clean-up.

Richard Grenville 6d36ef2d0f Feature #16: Advanced window matching
- 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.
2013-01-28 21:39:38 +08:00
Richard Grenville 00424b1082 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().
2013-01-24 13:38:03 +08:00
Richard Grenville 58c0ecec40 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).
2013-01-19 20:20:27 +08:00
Richard Grenville e60fe72dcb Bug fix #75: --invert-color-include not working & others
- Fix a small bug that breaks --invert-color-include if no other
  blacklists are present. Thanks to MaskRay and xiaq for reporting.

- Disable --unredir-if-possible for multi-screen setups.

- Fix a bug that causes --no-fading-openclose to have no effect in some
  cases. Add w->in_openclose to keep track of window open/close state.
2013-01-13 13:44:05 +08:00
Richard Grenville 2165c42d27 Feature #75: Invert window color
- Add window color inversion (--invert-color-include). It means 2-3
  times extra painting, so performance issues are likely to appear.  I
  hope I could find a faster way to invert colors.

- Rename some functions.

- Fix update of some window properties after window type/data change.
  Hopefully this will be helpful for #73.

- Split win_build_picture() from win_blur_background().

- Correct memory leak of ps->focus_blacklist during reinitialization.

- Add win_upd_t and win_upd_run(), to reduce duplicate window property
  updates. But is unused right now.

- Limited tests are done overall. Bugs to be expected.
2013-01-12 22:44:46 +08:00
Richard Grenville 57c5854fd0 Improvement: Use select() for main loop
- Back to using select() for main loop. Thus we are not longer relying
  on libevent.

- Add generic timeout system (untested) to prepare for D-Bus support.

- Drop troff man pages. Revise Makefile to improve documentation
  building, fix double LDFLAGS inclusion, and re-add -lrt. This turns
  asciidoc into a build time dependency.

- Change fading time calculation.

- Add --logpath and ostream_reopen() for debugging with -b.

- Drop unused lceil_ntimes() and other helper functions.

- Only very limited tests are done. Bugs to be expected.
2013-01-11 21:31:02 +08:00
Richard Grenville 7188054825 Bug fix #77 incorrect border_width handling & #73 window data issue
- (Hopefully) fix all incorrect handling of w->a.border_width in compton
  (#77). Thanks to baskerville for reporting.

- Attempt to fix #73 by correcting a mistake that window data is fetched
  from the wrong function. Thanks to zakkak.

- Add git commit/tag detection to Makefile for automatic versioning.

- Change -lGL linking order, to fix a segmentation fault caused by
  something in nvidia-drivers under FreeBSD, mentioned in #74. Thanks
  for the report from DachiChang.

- Link to -levent_core instead of -levent in Makefile. We might move to
  libev soon, though.

- Increase SWOPTI_TOLERANCE to handle the extraordinary delay of
  kqueue() under FreeBSD. Thanks for DachiChang's report.

- Add helper function dump_drawable() for debugging.

- Replace XInternAtom() calls with get_atom().

- Remove -lrt as it's unneeded.
2013-01-09 20:41:18 +08:00
Richard Grenville 3521f10a97 Improvement #74: Use libevent for main loop
- Use libevent for main loop. I will explain the reasons in #56 later.
  The preferred libevent version is 2.x, yet 1.4.x should work as well.

- As a result, compton now should build fine on *BSD. Thanks to
  DachiChang for the FreeBSD build issue report.

- Another consequence is we now use microsecond-level timing all the
  way. Nanosecond-level code will be dropped soon. Start using long
  instead of unsigned long to represent time in milliseconds, as both
  can't hold the full epoch time in ms, anyway, and a signed type
  requires less care in subtraction. Wrap the epoch time in ms to 15
  days.

- Fix broken NO_VSYNC_DRM and NO_VSYNC_OPENGL compile-time options.

- Use git revision number for versioning in Makefile, and other small
  improvements.

- Reorganize struct _win. Drop unused w->damaged_sequence. w->damaged is
  turned to bool.

- Add type and format to winprop_t, as preparation for the new condition
  format.

- Add w->shadow_force and w->focus_force, to prepare for D-Bus support.

- Rename wid_get_prop() to wid_get_prop_adv() with more options. Add
  wrapper function wid_get_prop().

- Add some extra helper functions, for D-Bus support later.

- Make some functions return a bool value to indicate if it's
  successful.

- Modify add_win(), use a static const structure to initialize the new
  struct _win.

- Add some helper macros, like printf_err(f)(q). Make some errors fatal.

- Rename some types, constants, and functions. Code clean-up.

- Check for time disorder in paint_preprocess() when calculating fading
  steps.

- Rename evpoll() to swopti_handle_timeout(), and partially rewrite it.

- Make -h / --help legal.

- Known issue: compton segfaults on FreeBSD with nvidia-drivers, unless
  NO_VSYNC_OPENGL is used. Will look into it later. Thamls to DachiChang
  for reporting.

Richard Grenville 1bfe21efb5 Improvement: Dynamic blur strength & improved frame blur performance
- Remove the region expansion design in win_blur_background(). I must be
  sleep-walking when I wrote that!

- Improve performance of blurring when a window is opaque but its frame
  is transparent.

- Adjust blur strength according to window opacity.
  --blur-background-fixed restores the old behavior.

- Add "use_offset" parameter to a few functions for convenience. Code
  clean-up.
2012-12-15 20:07:45 +08:00
Richard Grenville 22cabf7c89 Feature #69: Blur window background
- Add window background blur support (--blur-background &
  --blur-background-frame), with X Render convolution filter.
  The performance sucks. The performance when the window is opaque but
  frame is transparent could be improved, but there are two possible
  ways and I'm hesitating.

- Known issue: The blurring effect looks very ungraceful during fading.
  I could partially fix the problem, but it probably isn't easy to fix
  it completely.
2012-12-14 20:32:46 +08:00
Richard Grenville a77aaf0718 Misc: Code cleanup
- Move some long functions to ./src/compton.c .

- Add DEBUG_LEADER.

Richard Grenville 848687b853 Feature #65: Auxiliary window detection
- Add auxiliary window detection (--detect-transient &
  --detect-client-leader). Thanks to SmilingHorse for inspiring me. The
  implementation is not too speed-efficient, and bugs are to be
  expected.

- Known issue: auxiliary window detection may not work too well with
  windows that are never mapped, for example as client leader.

Richard Grenville 33171e8933 Feature: Wintype-based focus exclusion
- Add "focus" to the wintypes settings in compton.conf, to mark windows
  of certain window types to be always focused. Replaces the ugly
  is_normal_win().

- Add a ON/OFF/UNSET switch_t type, but it's unused currently.

- Mark client_win if the window client detection hasn't been performed
  when we detect WM_STATE's presence in ev_property_notify(), for
  performance.

Richard Grenville 7d70f3dc13 Bug fix #68: Second attempt to fix client window detection
- Attempt to fix client window detection when WM_STATE property is not
  yet set when the window is mapped. Thanks to kinclma1 for reporting.

- Apply stricter checks for whether window is mapped in
  determine_evmask() and win_mark_client().

Richard Grenville 812ba93516 Bug fix #68: Possible fix for failure in client window detection
- Note I'm not in the best state today (bad cold & sleep-deprived). This
  commit is likely to introduce bugs.

- Attempt to fix client window detection failures happening when compton
  searches for client window before it's ready.

- Fix build failure with <libpcre-8.20. Thanks to @pvanek for reporting
  in #51.

- Move client window detection to a new function win_recheck_client().

- Add win_unmark_client(), which unmarks a client window.

- Rename a few functions.

- Split fetching of values of type-Window properties to a new function
  wid_get_prop_window().

- Add extra safety checks and assert calls to various functions, to
  expose potential bugs.

- Fix a memory leak that w->role is not freed on window destruction.

Richard Grenville a7189263e1 Feature: WM_WINDOW_ROLE matching
- Add support of matching WM_WINDOW_ROLE value. Thanks to Vladimir A.
  Pavlov!

- Thanks to Vladimir A. Pavlov for reporting the issues caused by
  missing client window, fixed in the last commit!

- Fix a memory leak in wid_get_text_prop() and wid_get_name(). Xlib
  documentation did not mention how to free the value XGetTextProperty()
  returns, so my fix could lead to troubles.

- Set focus out in unmap_win(), and add w->leader, to prepare for
  subsidiary window detection.

- Abstract update of a single string window property to
  win_get_prop_str().

- Change wid_get_name() to rely on wid_get_text_prop() as much as
  possible.

- Correct a typo in win_get_prop_str() that could cause unnecessary
  update of shadow state and window focus.

Richard Grenville 983803aa9f Bug fix: Dynamic inactive dim & client window changes
- Make inactive_dim opacity change according to window opacity by
  default, so it looks better when fading. --inactive-dim-fixed restores
  the old behavior.

- Make client window default to the window itself. Add w->wmwin to
  represent whether the window looks like a WM window instead. A side
  effect is, the window type of WM windows are changed from unknown to
  normal, making it necessary to use --mark-wmwin-active to avoid
  considering them unfocused.

- Add check of PointerRoot to recheck_focus() to avoid BadWindow errors
  when the root window is focused.

- Add a few macros to simplify debugging code.

- Add DEBUG_FRAME.

Richard Grenville 9e66fd5b3f Misc: Man page updates
Update Asciidoc man page.
2012-12-04 22:34:24 +08:00
Richard Grenville 72c18b6219 Feature #65: --focus-exclude
- Add --focus-exclude, which should be used with a list of conditions to
  set certain windows to always be considered focused.

- Change focus determination process, with a newly added w->focused_real
  that reflects whether the window is actually focused, while w->focused
  represents whether compton considers it focused. The primary
  difference is now when a window considered focused because of
  --mark-wmwin-focused or --mark-ovredir-focused receives a FocusOut
  event, it's still considered focused by compton.

- Change opacity target and dim state calculation so that it's done at
  most once every paint.

- Split window opacity property fetching from calc_opacity() to a new
  function win_update_opacity_prop().

- Silence a warning in wid_get_prop_wintype().

- Rename a few functions. Code clean-up.

- My time is very limited currently, few tests are done, so this commit
  may very well introduce bugs.

- Known issue: Dim picture opacity does not change based on window
  opacity, causing somehow annoying effects when a window fades off.
