Summary: keyword and topic help broken in Pythonwin IDE
Initial Comment:
Using ActivePython 2.4.3 on Windows XP
While in the Pythonwin IDE, if I seek keyword help by
issuing the following command:
>>>help ('while')
I get:
Sorry, topic and keyword documentation is not available
because the Python HTML documentation files could not
be found. If you have installed them, please set the
environment variable PYTHONDOCS to
indicate their location.
My PYTHONDOCS variable is set to:
c:\python24\Doc\Python-Docs-2.4.2\ref
which appears to be correct (ie the help html files are
installed
there).
Searching this group, I found someone else complaining
about the same behavior with no clear resolution.

Since you are using the Pythonwin IDE, which was written and
is supported by Mark Hammond via the pywin32 project,
perhaps you should be visiting his project page instead:

Summary: Carbon.CF.CFMutableArray hangs interpreter
Initial Comment:
$ /opt/python2.4/bin/python
Python 2.4a1+ (#1, Jul 30 2004, 20:22:17)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin
Type "help", "copyright", "credits" or "license" for more
information.
>>> from Carbon.CF import *
>>> c = CFArrayCreateMutable(0)
>>> isinstance(c, CFMutableArrayRef)
True
>>> del c
The interpreter hangs after deleting c. This also happens when the
call to isinstance is left out.

I've just fixed it again in the trunk, and the bug is present in 2.4.3 as wel.
Very
strange...

Ronald,
I think I fixed this in CVS just before my holidays. Could you please
check?

It's infinite recursion...
- CF.CFMutableArrayRef has is a subtype of CF.CFArrayRef
- Both tp_del's call 'self->ob_type->tp_base->tp_dealloc' to deallocate
the instance.
- When the instance is an CFMutableArrayRef self->ob_type->tp_base
is CFArrayRef, which means we get:
1. Object refcount is 0, call tp_dealloc
2. Enter CFMutableArrayRefObj_dealloc
3. Call self->ob_type->tp_dealloc
4. Enter CFArrayRefObj_dealloc
5. Call self->ob_type->tp_dealloc
6. Enter CFArrayRefObj_dealloc
7. ...
I guess the right change is in Tools/bgen/bgen/bgenObjectDefinition.py:
outputDealloc.
Near line 138 this prints the problematic 'self->ob_type->tp_base-
>tp_dealloc'. I'd change this to:
Output("%s.tp_dealloc((PyObject*)self);"%(self.basetype,))

when I use gdb to check where the program hangs I always end up in
CFArrayRefObj_dealloc. This also happens when I continue to program
and break again later on.
It doesn't seem to be infinite recursion, the stack is 8 levels deep with
the code mentioned earlier.
However:
