Summary: decimal.Decimal("trash") produces informationless exception

Initial Comment:
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import decimal
>>> decimal.Decimal("-$123,456.78")
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\python25\lib\decimal.py", line 614, in __new__
self._sign, self._int, self._exp = context._raise_error(ConversionSyntax)
  File "C:\python25\lib\decimal.py", line 2325, in _raise_error
raise error, explanation
decimal.InvalidOperation

It should do something like float does ... better message, and show the 
offending arg:

>>> float("-$123,456.78")
Traceback (most recent call last):
  File "", line 1, in 
ValueError: invalid literal for float(): -$123,456.78
>>>

Summary: cStringIO no longer accepts array.array objects

Initial Comment:
It worked fine in 2.5 and 2.4.4

Python 2.5.1 (r251:54863, Jun  2 2007, 19:09:15) 
Type "copyright", "credits" or "license" for more information.

In [1]: from cStringIO import StringIO

In [2]: from array import array

In [3]: a = array('B', [0,1,2])

In [4]: StringIO(a)
---
 Traceback (most recent call last)

/Users/reedobrien/ in ()

: expected a character buffer object


Recompiling with the 2.5 cStringIO.c it works.

Python 2.5.1 (r251:54863, Jun  2 2007, 20:06:12) 
Type "copyright", "credits" or "license" for more information.

In [1]: from array import array

In [2]: from cStringIO import StringIO

In [3]: a = array('B', [0,1,2])

In [4]: StringIO(a)
Out[4]: 



I blame Visual Studio. 
I don't know enough c to fix it.

It appears this is the change that broke it.
http://svn.python.org/view/python/branches/release25-maint/Modules/cStringIO.c?rev=52302&r1=51333&r2=52302

This is the log entry from that changeset:
Bug #1548891: The cStringIO.StringIO() constructor now encodes unicode
arguments with the system default encoding just like the write()
method does, instead of converting it to a raw buffer.
 (backport from rev. 52301)


Perhaps the cPickle module should be used instead...

BUT at first glance the following seems to make both work:
  if (PyUnicode_Check(s)) 
{
if (PyObject_AsCharBuffer(s, (const char **)&buf, &size) != 0)
{
PyErr_Format(PyExc_TypeError, "expected character 
buffer, %.200s
found",
s->ob_type->tp_name); 
return NULL;
}
}
  else
{
if (PyObject_AsReadBuffer(s, (const void **)&buf, &size) != 0)
return NULL;
}

But the more I think about it the more I think cPickle is more appropriate
for this purpose.  In that case I should make a blurb for the docs about
not storing arbitrary data in cStringIO. 

Either way I am attaching the cStringIO.c file that worked for me...
File Added: cStringIO.c

[ python-Bugs-1770416 ] Decimal.int overflows for large values

Summary: Decimal.__int__ overflows for large values

Initial Comment:
This also affects Decimal.__hash__, since it [indirectly] calls Decimal.__int__.

>>> from decimal import Decimal as D
>>> e = D("1e1234567890987654321")
>>> int(e)
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.5/decimal.py", line 1501, in __int__
s = ''.join(map(str, self._int)) + '0'*self._exp
OverflowError: cannot fit 'long' into an index-sized integer
>>> e = D("1e1234567890")
>>> int(e)
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.5/decimal.py", line 1501, in __int__
s = ''.join(map(str, self._int)) + '0'*self._exp
MemoryError

Also, for values that do work this is incredibly slow if they are still fairly 
large.

Interesting problem! Mac_ver() basically uses gestalt() with a selector of
'sysv' and this will return '9' for the micro-version if it is 9 or
greater.
It could be fixed, according to
 by using three
calls to gestalt() with selectors 'sys1', 'sys2' and 'sys3', which will
return the three numbers correctly.

I'm not sure whether these selectors are always available, will
investigate.

Initial Comment:
Here is a list of chinese characters that can be read from a file [in GB18030 
encoding], but unable to encode to GB18030 encoding

detailed:
used codecs.open(r'file name', encoding='GB18030') to read the characters from 
a file, and try to encode them word by word into GB18030 with 
word.encode('GB18030'). The action caused an exception with 'illegal multibyte 
sequence'

the attachment is also the list.
