- 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.
- 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.
- Move some long functions to ./src/compton.c .
- Fix a small potential issue in win_set_focused() when a window with
neither leader nor client window is focused.
- Add DEBUG_LEADER.
- 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.
Add kompmgr settings reload method to twin DCOP
Fix up kompmgr kcontrol module
Make default TDM login screen appearance more like the rest of the TDE login system
- 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.
- 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().
- 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.
- 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.
- 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.
- 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.
- Fix a bug that causes wrong focus detection result in Awesome and
maybe other window managers, when --use-ewmh-active-win is enabled and
_NET_ACTIVE_WINDOW changes before the newly-focused window is mapped.
- Fix a typo that causes more than one window to stay focused after a
window destruction with --use-ewmh-active-win.
- Fix a bug that find_clientwin() incorrectly returns a window when
window ID 0 is passed to it.
- Check for window ID 0 in update_ewmh_active_win().
- Create a session_t structure, to get rid of most global variables and
let information pass in/out mostly through parameters. Huge changes,
so bugs may very well appear. I'm worried about resource leakages, in
particular.
- Add gcc attributes on various functions.
- Add Doxygen configuration.
- Replace much Xlib Bool with C99 bool.
- Add and adjust some comments.
- Drop unused parameters from some functions.
- Cache default Visual and Depth, mainly to shorten code.
- Rename some types, variables, and functions.
- Add win_ev_stop() and set_ignore_next() for convenience.
- Modify wid_get_prop_wintype() and wid_get_opacity_prop() to use
wid_get_prop().
- Rename --respect-attr-shadow to --respect-prop-shadow.
- Fix a memory leak in --respect-prop-shadow.
- Many other small changes.
- Optionally unredirect windows when there's a fullscreen opaque window on
the top of the stack (--unredir-if-possible). Experimental. Known
issues:
* Screen flickers when redirecting/unredirecting windows.
--paint-on-overlay seemingly minimizes it (Thanks for hints from
mutter), but still noticeable.
* It probably does not play well with vdpau in some cases.
- A debug option DEBUG_REDIR is added.
- Fix a bug that reg_ignore are not expired when a CirculateNotify is
received.
- Add extra safe guards in some places, which could be bad for
performance.
- Remove some abundant code.
- Add support for reading _COMPTON_SHADOW property from windows
(--respect-attr-shadow). Presently the only defined behavior is, if
_COMPTON_SHADOW is set on the highest ancestor below root window of a
window (usually the WM frame), it's format is 32-bit, type is CADINAL,
value is 0, the window will not get a shadow. The format and behavior
could change in the future without prior notification.
- Fix an issue in fork_after() that may cause some streams to remain
open. My mistake.
- Attempt to reduce determine_shadow() calls from map_win() by
separating some raw handler functions out.
- Fix a bug that causes rendering issues if a opaque window changes
shape.
- Remove abundant handling code in paint_preprocess() when generating
border_size as border_size() is no longer relying on
XFixesCreateRegionFromWindow() right now by default.
- Add extra code to print backtrace in DEBUG_ALLOC_REG.
- Move initialization of fade_time closer to first paint.
- Fix a bug that window content and some borders are not rendered if the
window has no border on particular sides when -e (frame-opacity) is
enabled, introduced in 66d3f30978. Just as what I said in the commit
message of the commit, "bugs are to be expected". :-S
- Fix a potential segfault in win_match().
- Slightly update CPackConfig.cmake to add dependency to libdrm.
- Silence a FORTIFY_SOURCE warning. Thanks to @smlx for reporting.
- Add -O2 -D_FORTIFY_SOURCE=2 to default CFLAGS in Makefile.
- Use a cleaner way to resolve the writing-to-freed-memory issue
mentioned in last commit.
- Add support for using _NET_WM_ACTIVE_WINDOW to track focus (rather
than using FocusIn/Out events) as --use-ewmh-active-win.
- Add wid_get_attr() and use it in place of XGetWindowProperty() in
various places.
- Remove dpy parameter from find_win() and find_toplevel() as it's unused.
- Fix a writing-to-freed-memory issue in paint_preprocess().
