[IronPython] 2.6 Beta 1 Bug: help() requires _getframe support which is now optional

2009-05-23 Thread Mike Krell 
With 2.6 beta 1 and without -X:frames:
 help()
Traceback (most recent call last):
File stdin, line 1, in module
File C:\Program Files\IronPython 2.6\Lib\site.py, line 428, in __call__
File C:\Program Files\IronPython 2.6\Lib\pydoc.py, line 53, in
C:\Program Files\IronPython 2.6\Lib\pydoc.py
File C:\Program Files\IronPython 2.6\Lib\inspect.py, line 950, in
C:\Program Files\IronPython 2.6\Lib\inspect.py
AttributeError: 'module' object has no attribute '_getframe'

This is now item 22640 on CodePlex.

[IronPython] Performance of dir

2009-05-23 Thread Michael Foord 

Hello all,

On IronPython 2.0.1 the last line of this code takes ~4 seconds the 
first time it is executed:


 import clr
 clr.AddReference('System.Windows.Forms')
 from System.Windows.Forms import *
 dir(Form)

Form.__dict__.keys() (which for a .NET type is equivalent) takes ~1 
second or less. What extra work is dir doing? (Is it pulling in the xml 
docstrings?)


Thanks

Michael

Actually they're not equivalent, my bad:

 len(Form.__dict__)
287
 len(dir(Form))
540

Thanks
