[Bug 1030278] Re: Quantal failed to install: ubiquity crashed in apt/progress/text.py in pulse: OverflowError: Python int too large to convert to C long

[Barry Warsaw]

Okay, this is clearly a problem in StrSizeToStr() and I think both bugs
are related to this.  First, StrSizeToStr() never checks whether an
exception occurs during conversion, so that's likely the problem of the
bogus traceback.  Second, StrSizeToStr() needs to PyLong_Check()
*before* it PyInt_Check()s because in Python 3, the latter is aliased to
the former, however, if the object is an *actual* PyLong, it will be
convertable to a double (as per PyLong_AsDouble()) for more values than
it will be convertable to a long (as per PyInt_AsLong(), a.k.a. in
Python 3, PyLong_asLong()).

The attached diff should fix both problems.  I've tested it with various
values in an i386 chroot and it seems to work correctly now.

Just don't try to convert 21474836480000000000000000000.  I guess
SizeToStr() can't handle anything over thousands of yottabytes.  Darn, I
might have to return my new hard drive.  This patch doesn't do much
about that.
