Topic: Bug: ZIPE not freeing up memory / closing stream after usage?

Hi!

In my "Pocket Radio Player" I have a memory leak when I use the stream functions of your module a lot.
It also seems that the zip file is still "locked", even when I already have opened another one.

Example line:
ButtoIco_stop:TIconstrip=LoadIconStrip("zipe::skins\"+filename+"::prp_stop.png")

Is there a way to force the wrapper to close the stream / zip file and free the memory allocated?
The bmx Garbage Collector doesn't help here at all.

Thanks.

Grisu

Re: Bug: ZIPE not freeing up memory / closing stream after usage?

Here's a quick example.

Just read out an image of a zip file constantly and the task mananger memory usage will go up like crazy while the GC Collector stays the same?

I have already posted that issue in the BMX bug forum. But no one could help so far.

If you have any idea or wild guess, please let me know.

Framework brl.Jpgloader
Import brl.PNGloader
Import brl.Pixmap
Import gman.zipengine

SuperStrict 

Global MinMemUsage:Long=GCMemAlloced()
Global MaxMemUsage:Long=GCMemAlloced()
Global TempMemUsage:Long=0

While True <> False ' Endless loop!

Local ButtoIco_exit:TPixmap=LoadPixmap("zipe::skins\prp_red_win7.skn::prp_about.png")  ' Just an ordinary image file
TempMemUsage:Long=GCMemAlloced() 
If TempMemUsage > MaxMemUsage Then MaxMemUsage=tempMemUsage

Print "Min: "+MinMemUsage
Print "Max: "+MaxMemUsage
Print ""
Delay (10) ' free a little CPU time

Wend
End
