I thought restricted mode had been removed from Python but it seems to be active for Python 2.3.5 +.
I'm using the JEP product which allows integration of Java with Python (see http://jepp.sourceforge.net) via starting a Python interpreter in the same process as the JVM. This integrates with python via the C interface, allowing the user to 'eval' python code (amongst other features). It seems that since Python 2.3.5 any threads (using the threading module) created via code that has been evaluated through the jep.eval() interface (i.e.Python C interface )are executed in restricted mode and cannot, for example, create files. Code that is just evaled (i.e not in a subthread) thread has no restrictions. The error reported is: IOError: file() constructor not accessible in restricted mode (see http://sourceforge.net/forum/forum.php? thread_id=1247793&forum_id=376782) - I've given a JEP specific example here. There seems to be a similar problem with mod_python (see http://www.modpython.org/pipermail/mod_python/2005- January/017129.html) Reading through the release notes for Python 2.3.5 I see: Bug #754449: threading.Thread will no longer mask exceptions raised during interpreter shutdown with another exception caused by attempting to output the initial exception. This fix also includes a backport of rev. 1.41 from HEAD. This might be the problem as it seems to involve the porting of 2.4 threading code back to the 2.3 tree. The error output is: Exception in thread Thread-1: Traceback (most recent call last): File "C:\Python24\Lib\threading.py", line 442, in __bootstrap File "<string>", line 5, in run IOError: file() constructor not accessible in restricted mode 2.4.1c1 (#63, Mar 10 2005, 10:36:41) [MSC v.1310 32 bit (Intel)] Creating file from main thread... Done Creating file from sub thread... Done Has anyone got any ideas about this? Thanks in advance, Max -- http://mail.python.org/mailman/listinfo/python-list
