[issue7309] crasher in str(Exception())

[Armin Rigo]

New submission from Armin Rigo :

The __str__ method of some exception classes reads attributes without
typechecking them.  Alternatively, the issue could be that the user is
allowed to set the value of these attributes directly, without
typecheck.  The typechecking is only done when we create the exception,
but not later.  Example:

>>> u=UnicodeTranslateError(u'x', 1, 5, 'bah')
>>> u.reason = 0x345345345345345345  
>>> str(u)
"can't translate characters in position 1-4: E\x03"

The 'E\x03' comes from PyString_AS_STRING(reason).  By playing enough it
is probably possible to come up with a real crasher.

[issue7310] Unhelpful __repr__() in os.environ

[Kent Johnson]

New submission from Kent Johnson :

In Python 2.x, os.environ extends UserDict.IterableUserDict and
therefore os.environ.__repr__() shows the environment. This makes it
easy and intuitive to view the entire environment in the interactive
interpreter.

In Python 3.1, os.environ extends _abcoll.MutableMapping and uses
object.__repr__(). This is a much less useful representation.

I suggest adding this __repr__() method to class os._Environ (os.py line
380):

def __repr__(self): return repr(self.data)

[issue7311] Bug on regexp of HTMLParser

[Chiyuan Zhang]

New submission from Chiyuan Zhang :

Hi all,

I'm using BeautifulSoup to parsing an HTML page and find it refused to
parse the page. By looking at the backtrace, I found it is a problem
with the python built-in HTMLParser.py. In fact, the web page I'm
parsing is with some Chinese characters. there is a tag like  , note this is legacy html page where the
attributes are not quoted. However, the regexp defined in
HTMLParser.py is :

 attrfind = re.compile(
r'\s*([a-zA-Z_][-.:a-zA-Z_0-9]*)(\s*=\s*'
r'(\'[^\']*\'|"[^"]*"|[-a-zA-Z0-9./,:;+*%?!&$\(\)_...@]*))?')

Note that the Chinese character (also any other non-english
characters), so it fire an error parsing this. I'm not sure whether
the HTML standard allow un-quoted non-ASCII characters in the
attributes. If it allows, this seems to be a bug. and the regexp to
better be [^>\s] IMHO.

BTW: It seems something like :

[issue7312] Run some tests in a loop until failure

[Antoine Pitrou]

New submission from Antoine Pitrou :

It can be useful to run one or several of the regression tests in a
loop, until one of the tests fail. Here is a patch to do that.

(interesting thing, by the way: you can combine it with -j, in order to
run several instance of the test at once)

The patch generally looks good to me, but I think you overlooked line
507, where you do a pending.clear() in case of keyboard interrupt in -j
mode.  I tested it on trunk and it seems to work great, except when I
press ctl-C :)

[issue1294] Management of KeyboardInterrupt in cmd.py

[Ilya Sandler]

Ilya Sandler  added the comment:

> But currently, CTRL-C terminates the session instead of propagating
upstream

I am not sure I understand: currently Ctrl-C generates a
KeyboardInterrupt, which can be caught by the  application which can
then decide how to proceed (in particular it  can start another command
loop or exit with a meaningful message or anything else).

This patch would suppress KeyboardInterrupt and thus interfere with such
applications. Or am I missing something?
