Category: Python Library Group: Python 2.3 Status: Open Resolution: None Priority: 5 Submitted By: Thomas Heller (theller) Assigned to: Just van Rossum (jvr) Summary: Unbounded recursion in modulefinder
Initial Comment: modulefinder goes into unbounded recursion when a module named 'path.py', containing 'import os', is on sys.path.
Last part of the traceback: File "c:\python23\lib\modulefinder.py", line 255, in import_module m = self.load_module(fqname, fp, pathname, stuff) File "c:\python23\lib\modulefinder.py", line 285, in load_module self.scan_code(co, m) File "c:\python23\lib\modulefinder.py", line 342, in scan_code self._safe_import_hook(name, m, fromlist) File "c:\python23\lib\modulefinder.py", line 300, in _safe_import_hook self.import_hook(name, caller) File "c:\python23\lib\modulefinder.py", line 124, in import_hook q, tail = self.find_head_package(parent, name) File "c:\python23\lib\modulefinder.py", line 166, in find_head_package q = self.import_module(head, qname, parent) File "c:\python23\lib\modulefinder.py", line 237, in import_module self.msgin(3, "import_module", partname, fqname, parent) RuntimeError: maximum recursion depth exceeded
Running modulefinder with the '-x os.path' command line option prevents the recursion.
This is not really a contrived situation, there's a possibly useful path.py module from Jason Orendorff at <http://www.jorendorff.com/articles/python/path>

It has something to do with os.path. Adding 'os.path' to the excludes list, the problem does not appear.
Adding print statements it seems that mf is looking for os.os.os.os.os.......something, it seems that it recurses without noting that something failed.
If I had to fix this myself, I probably had to first step through these imports with the C debugger, and then through mf.

Hm, not really. Do you have any idea what's causing it?

<ping> Just, do you have time to look into this?
