Summary: modules search in help() crashes on insufficient file perms
Initial Comment:
In the python interpreter, in the interactive online
help, typing modules
throws a permission denied error (Errno 13) and dumps
the user back to the main interpreter if the user has
insufficient permission to read any .py file from the
site-packages directory.
Example:
~:$ ls -l /usr/lib/python2.4/site-packages/pygtk.py
-rw-r- 1 root root 2619 2005-02-20 14:18
/usr/lib/python2.4/site-packages/pygtk.py
~:$ python
>>> help()
help> modules html
Here is a list of matching modules. Enter any module
name to get more help.
HTMLParser - A parser for HTML and XHTML.
htmlentitydefs - HTML character entity references.

declarations in HTML and XHTML.

for interactive use.

That patch sounds pretty-much right, but I think it should
print some feedback to stderr instead of silently swallowing
the exception.

Could this just be silently skipped? i.e returning None if
the user does not have the corrept permissions to access a
particular file?
Just wrap the 'file = open(filename)' in pydoc.py: line 182
in a try: except block returning None if there's an error
(such as permission denied).
I have written a patch I can supply if anyone wants it and
if this is the Right Thing To Do (TM).

My apologies. The tageditor.py file had the same permissions
for my test as pygtk.py. The particular file is irrelevant
in this case, it only matters that a user has insufficient
permissions for any file in the site-packages directory.
