Hi guys -
If I execute the following:
###
from System.Diagnostics import Process
M = 1024 * 1024
import bigmodule
for i in range(1000):
m = reload(bigmodule)
print i, Process.GetCurrentProcess().PrivateMemorySize64 / M
###
(in IP 1.1.1), I see steadily increasing memory usage - the assemblies
created by reloading each module are not being garbage collected.
Talking to Giles (the boss here), he remembered a conversation with
someone at the Languages.NET conference about how some assemblies aren't
collectable, while others that are generated without debugging
information can be collected.
Looking at the source for PythonEngine I can see the
EngineOptions.ClrDebuggingEnabled property, with a comment saying
essentially the same thing.
However, when I try to use this with the following code, I still get
increasing memory usage.
###
from textwrap import dedent
from IronPython.Hosting import PythonEngine, EngineOptions
from System.Diagnostics import Process
M = 1024 * 1024
o = EngineOptions()
o.ClrDebuggingEnabled = False
p = PythonEngine(o)
p.Sys.path.append('.')
for i in range(1000):
p.Execute(dedent('''\
import bigmodule
reload(bigmodule)
'''))
print i, Process.GetCurrentProcess().PrivateMemorySize64 / M
###
So the assemblies generated from compiling the imported module are still
not collectable. (I've also tried running the first script in an
interpreter (with ClrDebuggingEnabled off) embedded in a C# application,
to make sure there's nothing untoward happening because of nested
PythonEngines, but I see the same behaviour).
Is there any way to have these modules collected? Is the situation the
same in IP 2.*?
Thanks,
Christian
