[REBOL] Another view recycling problem with images
From: roland::hadinger::arcor::de at: 14-Jun-2003 16:25
I just discovered the life2d.r demo has a problem with the garbage
Hard to explain, so here is a smaller version of the problem and
my preliminary workaround:
;; (tested with REBOL/view 1.2.1 and 1.2.8 on Windows XP Pro).
f1: make face [size: 1x1 edge: none]
f2: make face [size: 1x1 edge: none]
view layout [
box 50x50 rate 1 feel [
engage: func [f a e] [
if a = 'time [
loop 1000 [
f2/image: to-image f1
f1/image: to-image f2
loop 1000 [recycle] ; argh !!!!!!!!!!!!
The code above runs without crashing.
Now, in the line that is commented with the genuine rendition of
the scream that could be heard throughout my house (the "argh" :),
decrease the loop count to 1 (or even 0) and run the script again.
Much faster now! But after some time, the operating system will
run out of memory and crash.
This line is the workaround, but I don't quite understand it :)
Could anyone explain what I'm missing here?
