IOBox Memory Issue

vvvv beta general
1

Helo
Just discovered a memory issue.

To reproduce please:

*close vvvv and restart 40beta16
*open taks manager to observe memory usage of vvvv.exe
*only add one IObox (Value Advanced)
*change the value of the iobox by dragging the right mouse button
*the memory usage of vvvv.exe increases
*but does not fall back.

can somebody reproduce?

the quicker you patch the safer your patch. hehe!

btw. same behavior with IObox (Color)

I think it is the Undo stuff that fills up memory? But a few kb for 1 value… hmzz…

might be. mabe one of the devvvv gurus has an answer. ??

oh well i think west is right.
every action is put into the history and when dragging at an iobox there might be added some entries per second.
each history entry is a object structure representing an xml snippet.

  • PATCH nodename=“C:\bar\foo.v4p”
    • NODE id=“8”
      • PIN pinname=“secretparameterHACK!” slicecount=“1” values=“17.331”

(xml not supported by tiki?)

something like that. each tag or attribute is internally represented by an object to be able to be faster in case of undo/redo.

in the taksmanager it looks like 3KB or so for a single value change (when editing by keyboard). that could be the size of such a object structure. so i think that would be the explanation already.

thank you! maybe it would make sense to restrict the undo steps via commandline?
