i did as you said, the problem didnt go, but the memory consumtion was only  150K. then what i tried was to make only one static object of the class inside the module CMOpFuncionalidad.py, and put it right there, so my while-cycle script now is:
 
import sys
 
try:
 i = sys.path.index("scripts")
except:
 sys.path.append("scripts")
 

import CMOpFuncionalidad
 

try:
 #pyop = CMOpFuncionalidad.PyOperador()
 pyop = CMOpFuncionalidad.pyop
 
 if not pyop.variablesInicializadas:
  pyop.colocaOpBD(cmop, dba, connID)
 pyop.atiendeCM()
 #pyop.liberaRecursos()
 pyop = None
except:
 if pyop != None:
  #pyop.liberaRecursos()
  pyop = None
 
 raise
 
I.e. i initialize the object and the internal variables only once,  and now it only consumes 150 bytes each time. It seems IP beta was not able to GC the pyop object and the related variables, even no references were left for it (and the internal variables were cleaned inside the method pyop.liberaRecursos(). Now i dont know where the 150 bytes are being left, perhaps local variables memory isnt cleaned up neither (just a wild guess here :) ) ??
 
 
    Cheers...

The real problem is that by directly interfacing w/ the Engine APIs you’re not doing a simple import.  There is actually an Import API but that’s only going to import the code into the “default module” and not provide you w/ a convenient way to execute it.

    PS. The module the script loads with import (CMOpFuncionalidad.py) has 15 global-module variables, but with import the module loads only once...doesnt it ??

How are you executing the script file?  If you’re creating a new optimized module each time we won’t be able to collection the optimized module code.  If on the other hand you’re just compiling it as a helper method then when it’s done running we can collect the code.

 

In pre-RC1 we had a leak where creating a new PythonEngine would result in a leak of a SystemState and ClrModule which were being hung onto by an event rooted in the app domain.  So if you’re re-creating the engine each time you might be seeing that.  Also, now that I’ve mentioned events, you might want to check your own C# code if you’re using events:  It’s easy to forget to unhook one and leak memory because the event handler stays alive forever.

 

If none of those turn out to be the problem an option here would be to download the free CLR Profiler and look at the object type that is consuming the increased memory.  It’ll give you a nice graphical display w/ a block view of what’s referencing what.

    Hi....

 

    I have an IP-Embedded C# application (IP version IronPython 1.0.60523 (Beta) on .NET 2.0.50727.42, Yeah i know, im out of date, but i havent make the change to latest version because i saw there were some API changes :) ), i create one PyEngine, set some global variables and inside a while block i execute this little script every time:

 

import sys

 

try:
 i = sys.path.index("scripts")
except:
 sys.path.append("scripts")

 


import CMOpFuncionalidad

 


try:
 pyop = CMOpFuncionalidad.PyOperador(cmop, dba, connID)
 pyop.atiendeCM()
 pyop.liberaRecursosBD()
 pyop = None
except:
 pyop.liberaRecursosBD()
 pyop = None
 raise

 

The module CMOpFuncionaliad is an IPython script i wrote, it contains a class definition. Inside the scripts i use components defined in some assemblies i made (these are already loaded into the CLR). The problem is, after the Engine takes the usual 12M+- of memory it needs, every time the script executes it consumes 2M more, i dont have a clue why is this...Does this version of IP have memory problems ? Or what else could be ?? If you need to see CMOpFuncionalidad.py let me know and ill send it....

 

   

    Thanks for your help....

 

    Greetings...
