Using an existing Python installation
by Mike Casaday 25 Feb '04

25 Feb '04

Python for .NET is really cool! Here's something I found out while trying to get it to work with my existing Python 2.3 installation. The README says: > **Can I use it with my existing Python installation?** > > Yes, at least on win32 systems. Just copy the files > Python.Runtime.dll and CLR.dll from the PythonNet directory to the > root directory of your python installation. > This answer comes with one caveat in my experience. For some reason you have to 'import CLR' before trying to import anything else from the .NET runtime. This isn't the case if I use the Python executable included in PythonNet-1.0-beta1.tgz, only if I use my existing Python installation. So this fails: from CLR.System.Reflection import Assembly Assembly.LoadWithPartialName('SomeNamespace') import CLR.SomeNamespace as SomeNamespace But this works: import CLR from CLR.System.Reflection import Assembly Assembly.LoadWithPartialName('SomeNamespace') import CLR.SomeNamespace as SomeNamespace Is it possible I'm doing something wrong (more than likely)? Is this a bug? Is this expected behavior? ZODB requires you to 'import ZODB' before you do certain things, so I wouldn't be surprised... ______________ mike P.S. I'm now playing around with the TrueVision3D game engine using Python, something that I couldn't really do until now. I'm happy I saw a link to this project from Daily Python-URL.

RE: [Python.NET] Problem whith DirectX device creation under pythonnet

[Copying the list on this as well, as it is probably relevant to everyone sooner or later...] Looking at this, I see what the issue is but I'm not sure how to address it, other than by documentation. The problem is the distinction between value types and reference types and how that distinction affects you when writing in Python. To take a boiled-down version of your example: items = CLR.System.Array.CreateInstance(Point, 3) for i in range(3): items[i] = Point(0, 0) items[0].X = 1 # won't work!! While the spelling of 'items[0].X = 1' is the same in C# and Python, there is an important and subtle semantic difference. In C# (and other compiled-to-IL languages), the compiler knows that Point is a value type and can do the Right Thing here, changing the value in place. In Python however, "everything's a reference", and there is really no spelling or semantic to allow it to do the right thing dynamically. The specific reason that items[0] itself doesn't change is that when you say 'items[0]', that getitem operation creates a Python object that holds a reference to the object at items[0] via a GCHandle. That causes a ValueType (like Point) to be boxed, so the following setattr ('.X = 1') *changes the state of the boxed value, not the original unboxed value*. Because there are no value type semantics or syntax in Python, there's not much the runtime can do about this :( The workaround is to do what you did, which is to make all of your changes to the boxed copy and then set (or re-set) the item in the array. This is not unlike some of the cases you can find in C# where you have to know about boxing behavior to avoid similar kinds of 'lost update' problems (generally because an implicit boxing happened that was not taken into account in the code). This is the same thing, just the manifestation is a little different in Python. The rule in Python is essentially: "the result of any attribute or item access is a boxed value", and as your example shows that can be important in how you approach your code. I've added a TODO to put a section about this into the docs - I'm sure it will be a FAQ. Brian Lloyd brian(a)zope.com V.P.

Python.Net affected by currently somewhat broken .Net Multithreading?
by Martin Kretschmar 10 Jan '04

10 Jan '04

Hello, the well respected german computer magazine c't reports in an article of its release 26/03 on page 214, that the .Net multithreading support currently suffers from several strangeness factors. The class ThreadPool suffers from several anomalies: The thread pool of a process is limited by 25 threads per processor. GetMaxThreads() and GetAvailableThreads() deliver the values 25/25 with .Net 1.0 and 25/1000 with .Net 1.1. The new threads obey to a pretty ackward activation pattern, new threads are started with individual offsets of 500ms to each other! The garbage collector starts after one minute after the demise of a thread. If new threads are requested in between, one again suffers the 500ms penalties from above. Further experiments trying to start all required threads in advance suffered from being queued automatically from thread 25 on, so this didn't help so much either. Running one thread under full load, makes the system take up to 5 seconds to start another thread. Attempts to work without ThreadPool suffered also from several anomalies and could even crash the .Net executive: The executive is quiet sensitive when one tries to Resume() an already running process etc, which might mean some extra private bookkeeping. Attempts with subclassing BaseThread worked but occasionally resulted in a termination with return code 0 with .Net 1.0 and a reported stack overflow with .Net 1.1. Closing a window while one owns homemade background thread is running creates a zombie thread. Altogether the authors hope, that further releases of .Net like .Net 2.0 will help to improve the situation. Regards, Martin

Initial Script Directory?
by Michael Reitzenstein 09 Jan '04

09 Jan '04

I have almost finished my first full project using .Net & Python, however when trying the program out on other computers I have hit a problem when importing modules. I couldn't figure out how to set the directory that Python should search to import modules when I first started integrating Python into my application, so I did a kludge-y method where I copied the script into the program's main directory, ran it, and then deleted the script and its compiled equivalent once it had been ran. This works fine on my machine - but I sent it to my friend to test out, and it wouldn't work. The scripts would copy over fine into the program's main directory, but an exception would be tripped when attempting to import the module. I am guessing that the directory that Python searches in is incorrect (not defined?) on their machine. I attempted the following at the very start of my program: string Dir = System.Windows.Forms.Application.ExecutablePath; System.Environment.CurrentDirectory = Dir.Replace( "Buildmeister.exe", "" ); ProgramDir = System.Environment.CurrentDirectory; Python.Runtime.PythonEngine.Initialize( ); Python.Runtime.PythonEngine.RunSimpleString( "sys.path[ 0 ] = '" + ProgramDir + "'" ); Python.Runtime.PythonEngine.RunSimpleString( "chdir( '" + ProgramDir + "'" ); ...But it doesn't work! Is there any simple way to set the directory that python searches for modules? --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
