[REBOL] [view] crashing...
From: moliad::aei::ca at: 14-Mar-2004 14:31
I've been working hard on glayout, and its now entering clean-up stage. I had
noticed a wild memory leak : EVERY new window would gobble up 6MB... even
closed... only 300kb would come back.
that when I noticed that I was re-creating a new style for every window...
somehow, that is staying in ram even though the window is not visible and all of
its reference (that I control) are set to none.
I have changed method, Now, and am creating the style once and re-using it on
Now with the shared style, opening a new window is about 50 times faster, but I
loose 1 MB per window. Even when using vid direcly, I noticed a rather large
200-300 kb memory hole...
glayout, had NEVER crashed once within the two weeks of operation, and now,
since my style is shared, I can make rebol crash just by opening several
windows EVERY time it gets started ... when it crashes is upon opening or
closing a window. The actual number or windows I can open before a crash is
completely variable , but I am guessing that its whenever a garbage collection
Furthermore I still get a memory leak ON EACH window but... its already better
since only 1MB is leaking ... not that its great... but better.
if it where only a fact that a function block keeps a reference to the last
window opened, I should be getting a leak only the first time IMO... maybe it is
view or layout themselves which have a leak, and since I am calling vid several
times, it eventually creates larger leakeage...
I am using v1.2.10...
has anyone had bad experiences like this one, or know of any specific issues
with styles (using the stylize function) ?
note that as part of glayout, VID is automatically relaunched several times
within the same layout...
any help appreciated.
