Dennis Kaarsemaker [EMAIL PROTECTED] added the comment:

pydoc.py from head actually does work around it in some places, but not
all. Will send a patch.

[issue2519] Typing 'modules' in the interactive help system fails when imports fail

2008-03-31 Thread Dennis Kaarsemaker 

New submission from Dennis Kaarsemaker [EMAIL PROTECTED]:

If a certain module cannot be imported, this error is not caught and
warned about by pydoc, but will cause 'modules' to fail. This could be
considered a bug in the module but it would still be nice if 3rd party
modules cannot break pydoc. Example:

[EMAIL PROTECTED]:~$ python
Python 2.5.2 (r252:60911, Mar 12 2008, 13:36:25) 
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu4)] on linux2
Type help, copyright, credits or license for more information.
 help()

Welcome to Python 2.5!  This is the online help utility.
[... snip ...]

help modules

Please wait a moment while I gather a list of all available modules...

Traceback (most recent call last):
  File stdin, line 1, in module
  File /usr/lib/python2.5/site.py, line 342, in __call__
return pydoc.help(*args, **kwds)

for importer, modname, ispkg in pkgutil.walk_packages():
  File /usr/lib/python2.5/pkgutil.py, line 125, in walk_packages
for item in walk_packages(path, name+'.', onerror):

[... snip -- the actual error isn't important ...]
OperationalError: no such table: falcon_configurationkey

 

I think it would be relatively easy to work around such bugs in 3rd
party modules by passing a callable to walk_packages that will give a
warning when an import fails instead of breaking.
