Hello, I have a question about the "subprocess" module. I am unable to "import subprocess" in my scripts. Will IronPython will support this in the future, or, perhaps is it intentionally not supported? (Or perhaps I am doing something stupid, and it should work?)
I recently began using IronPython because I had both Python scripts and .Net classes that I needed to use together. So far I have been pretty pleased with how well everything is working. My biggest problem has been that the os.system() call does not work in IronPython. I notice that this was raised as an issue in Sep '06 (http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=2982). While hunting around for an alternative, I found the following text in the library reference (http://docs.python.org/lib/module-subprocess.html): "The subprocess module ... intends to replace several other, older modules and functions, such as: os.system os.spawn* os.popen* popen2.* commands.*" For this reason, I thought that perhaps "os.system" was going to become deprecated in favor of "subprocess", and that might explain why this issue has not been addressed. However, I am unable to "import subprocess" in IronPython. When I do so, an exception is raised because, "No module named fcntl". Digging into this a bit, I notice the following variable defined within subprocess.py (this is from ActivePython 2.5): mswindows = (sys.platform == "win32") And then many conditional statements of the form: if mswindows: ...#Windows specific code else ...#Non-windows code, presumably IronPython fails this check because sys.platform = 'cli', and thus is lead into using modules that are (I would guess) meant for Unix-based systems. Further, this behavior seems to be known - I noticed that this seemed to be accounted for in (what appears to be) the automatic test-suite code located here: http://www.codeplex.com/IronPython/SourceControl/FileView.aspx?itemId=296023 &changeSetId=21805 What's strange to me is that I couldn't find a single reference to using subprocess in IronPython anywhere. So perhaps this issue is widely understood by everybody but me (I'm relatively new to Python), or simply not an issue for anybody but me? Anyway, I was hoping somebody on this mailing list might have some insight to share. Thanks, Matt _______________________________________________ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
