ob_type in shared memory

Hello, I am writing an extension using shared memory. I need a data type that is able to reassign its 'ob_type' field depending on what process is calling it. Object 'A' is of type 'Ta'. When process 'P' is looking at it, it needs to have an 'ob_type' that is 'Ta' as process 'P' sees it. When

Find the location of a loaded module

I'm running into a problem that's rapidly reaching keyboard-smashing levels. I'm trying to import a module into Python, but it seems like Python is almost randomly loading the module from an entirely different directory, one that shouldn't be in the module search path. When I tell Python to load a

Re: Find the location of a loaded module

es, eventually it loads the module from the proper directory ('act2'). Then, I'll go back to the first directory, and find that it too will be loading the module from 'act2'. I'll refresh, and it'll load from 'act1' again. I'll refresh a couple times, and suddenly it's loading from 'act2' again. I'm seriously going insane. If anyone has any insight, please, please share it with me. Aaron -- http://mail.python.org/mailman/listinfo/python-list

Re: Find the location of a loaded module

Here's another clue: if I'm trying to run the script from the directory 'act1', but it's loading the module from 'act2', if I rename the module directory in 'act2' and refresh, the module still reports that it's running from '/home/www/---/docs/act2/story/game.pyc'... even though that files no long

And finally, an epilogue. So, the problem lies with how Python cached the modules in memory. Yes, the modules were in two different locations and yes, the one that I specified using its direct path should be the one loaded. The problem is, the module isn't always loaded -- if it's already in memor
