Re: [IronPython] Django 1.1 on IronPython 2.6rc2 findings
Intro... I, together with Mark Rees, wrote most of adonet-dbapi code in 2006. 2009/10/28 Markus Törnqvist m...@nysv.org: Here's the connect function (in its entirety) from mssql.py def connect(connstr): relevant_parts = [part for part in connstr.split(';') if not part.upper().startswith('PROVIDER')] connstr = ';'.join(relevant_parts) #return generic_connect(System.Data, System.Data.SqlClient.SqlConnection, connstr) Way too hacky for my taste but it gets the job kinda done. Indeed. The question is, what underlying Python DB-API 2 driver does django-mssql use? Is it http://pymssql.sourceforge.net/ ? Argument to connect() function in Python DB-API 2 compliant drivers is not standardized. In case of pymssql, it receives keyword arguments, so it should be handled in a manner similar to MySQLdb.py wrapper in adonet-dbapi. But from your hack it seems django-mssql's underlying Python DB-API 2 driver expects a string argument, so django-mssql is building string by itself -- this is ungood. Read psycopg.py wrapper in adonet-dbapi to see how to handle this. On the other hand, as I understand, Django does not handle paramstyle difference in DB-API 2 drivers, so this is kind of a lost cause. How do other Django DB backends deal with the issue? SQLAlchemy, fortunately, handles paramstyle difference by itself. -- Seo Sanghyeon ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

[IronPython] FePy status update
FePy seems to be dead, right? Sorry about that. This is a brief status update. And I could use it later as a changelog. How convinient. 1. I am now testing IronPython with CPython 2.6 standard library. FePy used 2.4 so far. Be sure to check collections.py issue Dave mentions here: http://knowbody.livejournal.com/13271.html 2. NAnt build system has been updated to the latest source layout change. My goal still is to do away with NAnt and improve Mono's implementation of MSBuild to build IronPython out of the box, but that hasn't progressed a bit, sorry. Dave wrote about the source layout change here: http://knowbody.livejournal.com/13980.html 3. ExtensionAttribute problem mentioned in the last December is gone. Mono bug on reference equality with generic constraints mentioned in March is still there. FePy trunk patches/latest has a workaround for this. Net result is that latest IronPython source drops from CodePlex compiles and runs with Mono! And no compiler warnings! (This has been my pet peeve, you know.) And I had no problem keeping it that way for some time. I updated IronPython on Mono reports page with relevant mails. http://fepy.sourceforge.net/doc/ironpython-mono-report.html 4. There is an IronPython bug that manifests only on Mono due to newline difference. The symptom is that expressions are not printed in interactive console. This took some time to debug, but there is a fix now. http://lists.ironpython.com/pipermail/users-ironpython.com/2009-April/010140.html 5. Current build on my local system generally works. It imports urllib and urllib2. This is quite a stress test... Not just import, but downloading webpages work too. On the other hand, importing decimal crashes Mono in segmentation fault!

[IronPython] IronPython 2.0 RC 2 on Mono
Currently you need Mono SVN (both to run and to compile). Using SVN r120972 below. The binary runs fine. IronPython includes its own copy of ExtensionAttribute, but this doesn't seem to work with Mono C# compiler: that is, extension methods don't get recognized as extension methods. This causes trouble where MetaObject is defined in Microsoft.Scripting.Core.dll, and its extensions are defined in MetaObjectExtensions in Microsoft.Scripting.dll. My hack below copies MetaObjectExtensions and its dependencies to Microsoft.Scripting.Core and patch it to be a partial class instead of a static class housing extension methods. Any better idea? Also there are some unused files in the source distribution. Below are steps I used to compile the source on Mono. Download source from http://www.codeplex.com/IronPython/Release/ProjectReleases.aspx?ReleaseId=19841 $ unzip IronPython-2.0-Src.zip $ cd IronPython-2.0 Some hacks... $ svn co -r 597 https://fepy.svn.sourceforge.net/svnroot/fepy/trunk/patches/latest build This deletes unused files and does copying mentioned above $ sh build/pre.sh Copies NAnt build file: it uses noconfig to avoid pulling System.Core.dll $ cp build/IronPython.build Src Patches $ patch -p1 build/patch-exthack $ patch -p1 build/patch-console Build $ cd Src $ nant -- Seo Sanghyeon ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

[IronPython] An issue with using System.Xml as a Python DOM implementation
I am not sure to whom this mail should be addressed. Please help if you know. I am considering the idea of using System.Xml as a Python DOM implementation again. After some experimentation, one issue is this: an idiomatic way to check for the type of DOM node in Python is: if node.nodeType == node.ELEMENT_NODE: nodeType is spelled NodeType with capital N in .NET, but that's fine. I can translate naming convention. The problem is that .NET's XmlNode type does not have attributes for DOM node types, that is, ELEMENT_NODE, ATTRIBUTE_NODE, etc. Instead, these attributes ara available under XmlNodeType enumeration, with wholly different names, like Element, Attribute, etc. My question is, why is this blatant incompatibility? DOM level 1 Core standard http://www.w3.org/TR/REC-DOM-Level-1/level-one-core.html seems to clearly say that Node interface should have constants like ELEMENT_NODE, ATTRIBUTE_NODE, etc. defined. -- Seo Sanghyeon ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

Re: [IronPython] Python Standard Library in IronPython
2008/10/29 Kenneth Miller [EMAIL PROTECTED]: I know I can access just about everything in the python standard library by simply adding it to the ironpython path, however this is not a good solution when writing dynamic applications in Silverlight. I can include the standard library with my silverlight application, but this bloats the package and causes horrible load times. I started writing some abstractions last night to do common path operations using whatever library is present (.Net vs cpy) when it dawned on me to simply re-map common functions in the python standard library to the .Net equivalent. Has something like this already been done? If not, does anyone have any interest in doing this? This is a good idea, and I actually planned to do this for path manipulation some time ago, named clipath (analogy to ntpath, posixpath, etc.). Another obvious candidate is clidom, reusing .NET's DOM classes. -- Seo Sanghyeon ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

CPython has (in addition to Global Interpreter Lock, since imported module can be a C extension) a lock around its importer: see imp.acquire_lock and imp.release_lock.

[IronPython] My takes on C Extensions for IronPython
The discussion is getting very confusing, so here are some of my takes on the issues. On the issue of P/Invoke declarations for Python/C API, Paolo Molaro wrote: The python API requires a couple dozen structure definitions plus a few dozen dllimport declarations. This can be about 200 lines of trivial to write declarative stuff. It's certainly more than 200 lines, and it's not completely trivial because some parts of Python/C API are C macros, not C functions. (Reference counting is the most important, but also getting type(=vtable) of Python objects and like.) The good news is that this part is already developed, debugged, and pretty much finished -- for Python 2.3 to 2.6, and for wide and narrow unicode builds of Python. Get it here (~ 1600 lines): http://pythonnet.svn.sourceforge.net/svnroot/pythonnet/trunk/pythonnet/src/runtime/runtime.cs Assuming that ZPL (which is OSI-certified) is okay, it would be strange not to use this. On the issue of compiling C or C++ to CLI, Keith J. Famer wrote: My impression was that they're working under the assumption that you cannot get C++ code to compile to pure managed (False, use C++/CLI as recommended on the Mono site), and that it must *compile* under Mono (laudable, but I doubt it's necessary -- I've never bothered to recompile the Python Libraries). Readers not familiar with the issue should read Mono documentation mentioned: http://www.mono-project.com/CPlusPlus I understand MC++ or Managed C++ is used to refer related technologies, but in the narrow sense it is a compiler that shipped with .NET 1.x which produced mix of managed and x86 code. I believe .NET 2.x compiler, i.e. C++/CLI is what is currently discussed. It would be nice to be able to compile without Microsoft tools, but I don't think it's essential. If assembly compiled with C++/CLI / clr:pure can be made to run on Mono that's fine. Also Mono page doesn't mention this, but GCC backend to emit CLI code *is* complete and working. It's available right now from GCC SVN. But it's yet another project, not Google Summer of Code attempts. This project is backed by STMicroelectronics, a big corporation, probably for its own use. http://gcc.gnu.org/projects/cli.html Remember, Mono doesn't need to be the sole provider of non-Microsoft CLI tools. :) I believe GCC/CLI can be made to help this project.
