COMMENTED ISSUE: str() or unicode() setting up unicode string, exception occurs.

orestis — Fri, 09 May 2008 13:13:44 GMT

String representation of the object to obtain a unicode() function tries to use. (C#: obj.ToString())

>>> a = 'A'
>>> a
'A'
>>> unicode(a)
'A'
>>> a = 'Ａ' # \uff21
>>> a
u'\uff21'
>>> unicode(a)
Traceback (most recent call last):
File , line unknown, in ##41
UnicodeEncodeError: ('unknown', '\x00', 0, 1, '')
>>> str(a)
Traceback (most recent call last):
File , line unknown, in ##42
UnicodeEncodeError: ('unknown', '\x00', 0, 1, '')

# CPython2.5.1 unicode () provides an exception occurs.
Comments: ** Comment from web user: orestis **

A simpler reproduction is:

== IronPython 2.0 B2 ==
>>> "\u039f"
'\\u039f'
>>> u"\u039f"
u'\u039f'
>>> unicode("\u039f")
'\\u039f'
>>> unicode(u"\u039f")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: ('unknown', '\x00', 0, 1, '')

== CPython 2.5.2 ==

>>> "\u039f"
'\\u039f'
>>> u"\u039f"
u'\u039f'
>>> unicode(u"\u039f")
u'\u039f'
>>> unicode("\u039f")
u'\\u039f'

COMMENTED ISSUE: SyntaxError(...).dict is not a dict

dinov — Thu, 08 May 2008 17:36:48 GMT

<Thanks>Michael Foord</Thanks>
<Test>Needed</Test>

Hello guys,

Attempting to access the '__dict__' attribute of a SyntaxError exception in IP2a8 *returns* an 'OperationFailed' object.

The codeop module (Python standard library) compiles source code and
*compares* the __dict__ attribute of SyntaxError exception instances...

(I can work around this bug for the interactive interpreter...)

It looks like this got fixed in beta 2 w/ some new type work (I thought it was still broken, but I guess not).

COMMENTED ISSUE: ToString(format) does not work with python long

Eloff — Thu, 08 May 2008 13:13:44 GMT

Perhaps it would be enough to implement it by converting the long to System.Decimal, and just using it's ToString(format) which works perfectly.

def ToString(self, format):
d = Decimal.TryParse(str(self))
return d[1].ToString(format)

I can't think of anyplace you'd want long.ToString(format) to be different to Decimal.ToString(format)
Comments: ** Comment from web user: Eloff **

I was wondering about that. No shortcuts here I guess.

COMMENTED ISSUE: ToString(format) does not work with python long

sanxiyn — Thu, 08 May 2008 09:20:16 GMT

Since Decimal has a finite precision and Python long an arbitrary precision, some Python long values can not be converted to Decimal.

CREATED ISSUE: dir() of a AssemblyBuilder instance shows the members of Assembly

COMMENTED ISSUE: metaclass not called when constructing classes that inherit from another class first

dinov — Tue, 06 May 2008 03:00:28 GMT

This one's a bit brain-melting.

class MetaClass(type):
def __init__(cls, clsname, bases, dict):
setattr(cls, "attr_%s" % clsname, "attribute set on %s by MetaClass" % clsname)
super(MetaClass, cls).__init__(clsname, bases, dict)

class Mixin(object):
__metaclass__ = MetaClass

class Parent(object):
pass

class Child(Parent, Mixin):
pass

>>> Child.attr_Child
# py> no error: attribute set on Child by MetaClass
# ip> AttributeError: 'type' object has no attribute 'attr_Child'
Comments: ** Comment from web user: dinov **

There's a couple of issues lurking here. First off type(Child) == type in IronPython and == MetaClass in CPython. But if instead you do:

Child = type('Child', (Parent, Mixin), {})
type(Child)

we both get to type(Child) == MetaClass. This reflects that we have 2 divergent code paths for creating classes. PythonType.__new__ does the correct meta-class search but PythonOps.MakeClass doesn't. Those should be unified. But we still don't get the attribute access correct!

COMMENTED ISSUE: PythonType.HasGetAttribute property does not detect inherited implementation.

dinov — Tue, 06 May 2008 02:40:26 GMT

IronPython 2.0 Alpha 8

Reproduce :

Install CPython 2.5
Install Bazaar 1.2
Start IronPythonConsole in debug mode from VS
execute

import sys
sys.path.append(r"c:\python25\lib")
sys.path.append(r"c:\python25\lib\site-packages")
import bzrlib

Without a debugger attached, the process now goes into an infinite loop. With debugger attached, code breaks in IronPython.Runtime.Operations.UserTypeOps.MakeGetMemberRule<T>, where sdo.PythonType.HasGetAttribute is checked.

The type in question is ImportReplacer from bzrlib.lazy_import ; it's parent type has __getattribute__ but this is not registered.

You can work around this by patching ImportReplacer with an explicit call to the parent type.

def __getattribute__(self, attr):
return ScopeReplacer.__getattribute__(self, attr)

bzrlib then successfully imports.
Comments: ** Comment from web user: dinov **

Fixed in beta 2 w/ the type work. HasGetAttribute is gone!

This appears to be fixed - it also appears to be the same issue at yield statements being broken at the console. I'm not sure what the underlying cause was but it could have been a DLR regression that was fixed.

COMMENTED TASK: Support interop between serialization and pickle

sanxiyn — Sun, 04 May 2008 08:22:36 GMT

Currently pickle and .NET serialization are completely independent. We should build a bridge between then so serializable classes can be pickled / unpickled and pickable classes can be seriailized / deserialized.
Comments: ** Comment from web user: sanxiyn **

One workaround is to use Python's copy_reg module to inject .NET serialization behavior to pickle. FePy has an example.

f_locals is critical for running Trac; it does some metaprogramming voodoo with it in the implementation of half its classes. SCons uses it as well; I'm not sure how critical it is there.

CREATED ISSUE: No signal module

IronPython (as of 2.0b2) does not implement the signal module. I don't know how easy it would be to actually implement but it would be nice to have it stubbed out so that applications that use it don't fail unnecessarily.

CREATED ISSUE: os.chmod followed by os.unlink fails

This is a weird one:
{{
IronPython 2.0 Beta (2.0.0.2000) on .NET 2.0.50727.1434
Copyright (c) Microsoft Corporation. All rights reserved.
>>> import os
>>> os.chmod('test.txt', 0777)
>>> os.unlink('test.txt')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
WindowsError: (13, "[Errno 13] Access to the path '...\\test.txt' is denied.")
>>>
}}

>>> import os
>>> os.chmod('test.txt', 0777)

}}

os.unlink (without a preceding os.chmod) works just fine on both. SCons uses this pattern while storing its signature files.

CREATED ISSUE: unicode.name == str.name == 'str'

Eloff — Sat, 03 May 2008 03:44:09 GMT

I just spent some time debugging a python module that breaks on IPY 2b1, and it boils down to the fact that unicode.__name__ is 'str' when it should be 'unicode'.

I understand IPY doesn't actually have byte strings, it just uses unicode strings for everything, so I don't know if this is easily fixable, or even if it should be fixed.
