the onscreen cursor shows the cursor of the current
focused window or the window it points at. if there
is no window, then we set the default cursor (nil).

- use free running unsigned indeces for window kbdq
- emalloc() vs malloc() in xfid

kbdfs already provides a /dev/kbdin file for the system, rio does
not need to provide one for the onscreen keyboard anymore.

xfidflush() now uses a simpler way to flush another xfid.
when we can send to Xfid.c channel, we know that the
xfid is completed. so all xfidflush() needs todo is to
do an alt sending to both Xfid.c and Xfid.flushc.
once the send to Xfid.c succeeds, we know the xfid is gone
and we can respond to the flush request.
theres no need to keep track of flush state anymore. so
Xfid.active and Xfid.flushing can be removed.
note, that it is ok to respond normally to a currently
flushed request.

flushing isnt optional for concurrently handled requests.
we need to ensure that Rflush is replied *after* the
origianl request.
so we assign the flushtag for *every* xfid in xfidctl(),
and filsysrespond() checks if the xfid was flushed
*after* replying and wakes up the flushing xfid.
|
|
when multiple flushes are send, they need to be replied
in order. we ensure this by having the flush xfid taking
over the flushtag (synchronized with a new fs->csyncflush
channel) so the next flush will flush the previous flush.

dont rely on postnote to shutdown client. instead, make reads on
cons, kbd and mouse error. when we mount a window system over
exportfs, the pid useless and even dangerous! pid should be
only used by clients forked by rio itself.
fix bug in resized(), goodrect() takes rect in screen coordinates!
make rectonscreen() fix window size if the window doesnt fit
on the screen.
improve goodrect() to check for windows outside of the screen or
bigger than screen without borders visible.

or was replied
due to the xfid handlers clearing flushtag too early, xfidflush might respond too early
causing spurious replies send later by the handler. now, we clear the flushtag in
filsysrespond *after* the reply was send. xfidflush will wait for us on the active
qlock.

we can't really change the Window *input from
outside the winctl() thread. the problem is
that the window might end up reading the
mouse (scroll, select) which makes the w->cctl
channel block once you try to talk to the
window again (from the mousethread). this also
means we have to coordinate window switchin
from the winctl proc waiting for the current
window to release the input and then take over.
thers a new Winctl message Topped that basically
does that now using Wakeup and a chan to
synchronize.

wrepaint() used to also set the cursor for the window
if it was current. this reset the corner cursors on
bandresize when one tried to attempt to size a window
that was not current. make repaint just repaint the
window and border. set cursor explicitely for hold
toggle.

use notefd in killprocs() insead of postnote() as the process
might'v exited. the notefd stays valid even if the particular
process it was originaly opend on exited. remove the Window.pid
field as its not needed.
dup() the notefd for interruptproc as the window might'v gone
away and closed the notefd file descriptor, resulting in us
writing to the wrong thing.
use snprint() instead of sprint() for safety.
fix bogus debug fprint().
add missing "visible" flushimage() after Reshaped winctl message
got handled. i assumed wsetname()/nameimage() would be enough,
it but does a invisible flush so softscreen doesnt get updated
immidiately.
do not make allocimage() failure in scrtemps() fatal. it wont
draw the window properly, but it gives the user a chance to
delete some windows to recover.

allocate all the colors in iconinit(), remove unused ones
like grey. rename darkgrey to paletextcol because thats
what it is used for. new approach to window image allocation.
we allocate the window with DNofill and let the window fill
itself. this reduces flickering especially with (-b) option
and makes rio resize feel a lot faster.
wrefresh() didnt work. now fixed.
|

resize. instead, use screen and omit the file if provided by the enviroment. allow unaligned reads.
