Hi list, I am not sure who to go to with this...
We have a large legacy CPython library set that makes extensive use of the pywin32 extensions Mark Hammond wrote. I would like to use IronPython to build a RESTful service around the use of this code, but have discovered that this will be problematic at best, and impossible at worst. I saw through some net searching that William Reade managed to get some portions of win32api to work last year using ironclad (http://www.mail-archive.com/users@lists.ironpython.com/msg08921.html) So I thought I'd try to see how far I could get with some of the win32 stuff... I managed to get win32api to import with a zillion warnings, but when I tried to import pythoncom, I got errors nesting down to a problem with the import of pywintypes. Looking into the code, it assumes that sys.platform startswith("win32") must be True if it's windows; this isn't the case with ipy; instead it's "cli". Ok, easy to modify, to get to the next issue in the onion, which I'm stumped on... 'import pythoncom' fails. I've worked through the code enough to track down the source of this to problems importing from the pywintypes dll. It turns out that in cpython: C:\> c:\Python26\python.exe Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] on win32 >>> import imp >>> imp.load_dynamic('pywintypes', r'C:\Windows\system32\pywintypes26.dll') <module 'pywintypes' from 'C:\Windows\system32\pywintypes26.dll'> That is, imp.load_dynamic() returns a module object for this. In ipy : C:\> C:\Program Files (x86)\IronPython 2.6\ipy.exe IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.4062 >>> import sys >>> sys.path.append(r'c:\ironclad-v2.6.0rc1-bin') >>> import ironclad >>> import imp >>> imp.load_dynamic('pywintypes', r'C:\Windows\system32\pywintypes26.dll') >>> That is, in ipy, the imp.load_dynamic() *doesn't* return a module, and raises no exception or anything that would indicate why this was the case. Which leads to the following questions: 1) Can anyone tell me why this is? 2) Is this an ironclad issue, an ipy bug, an incompatible change in imp's behavior in ipy, or something else? 3) Is this a path worth pursuing? 4) If not, can anyone give me any recommendations for what to use instead of ipy? 5) Also, as an aside, will ironpython ever support .pth files to augment the module search path?
