underlying dictionaries, there were no reasonable use cases (lexicographic
sorting of a list of sets is somewhat esoteric). Frees the operators
for other uses (such as strict subset and superset comparisons).
Updated documentation and test suite accordingly.
the inplace operators. The strategy is to have the operator overloading
code do the work and then to define equivalent method calls which rely on
the operators. The changes facilitate proper application of TypeError
and NonImplementedErrors.
Added corresponding tests to the test suite to make sure both the operator
and method call versions get exercised.
Add missing tests for difference_update().
immediately after the comparison, there in no use in caching the hashcode.
The test, 'if self._hashcode is None', never fails. Removing the caching
saves a few lines and a little time.
2. Replaced calls to Set([]) with Set() -- Timbot's suggestion
3. Fixed subtle bug in sets of sets:
The following code did not work (will add to test suite):
d = Set('d')
s = Set([d]) # Stores inner set as an ImmutableSet
s.remove(d) # For comparison, wraps d in _TemporarilyImmutableSet
The comparison proceeds by computing the hash of the
_TemporarilyImmutableSet and finding it in the dictionary.
It then verifies equality by calling ImmutableSet.__eq__()
and crashes from the binary sanity check.
The problem is that the code assumed equality would be checked
with _TemporarilyImmutableSet.__eq__().
The solution is to let _TemporarilyImmutableSet derive from BaseSet
so it will pass the sanity check and then to provide it with the
._data element from the wrapped set so that ImmutableSet.__eq__()
will find ._data where it expects.
Since ._data is now provided and because BaseSet is the base class,
_TemporarilyImmutableSet no longer needs .__eq__() or .__ne__().
Note that inheriting all of BaseSet's methods is harmless because
none of those methods (except ones starting with an underscore)
can mutate the .data element. Also _TemporarilyImmutableSet is only
used internally as is not otherwise visible.
wrong thing for a unicode subclass when there were zero string
replacements. The example given in the SF bug report was only one way
to trigger this; replacing a string of length >= 2 that's not found is
another. The code would actually write outside allocated memory if
replacement string was longer than the search string.
(I wonder how many more of these are lurking? The unicode code base
is full of wonders.)
Bugfix candidate; this same bug is present in 2.2.1.

methods that used to have a loop-over-subcases. Much simpler.
Rename perennial temp variable 't' to 'text'.

than raising TypeError when the other argument is not a BaseSet. This
made it necessary to separate the implementation of e.g. __or__ from
the union method; the latter should not return NotImplemented but
raise TypeError. This is accomplished by making union(self, other)
return self|other, etc.; Python's binary operator machinery will raise
TypeError.
The idea behind this change is to allow other set implementations with
an incompatible internal structure; these can provide union (etc.) with
standard sets by implementing __ror__ etc.
I wish I could do this for comparisons too, but the default comparison
implementation allows comparing anything to anything else (returning
false); we don't want that (at least the test suite makes sure
e.g. Set()==42 raises TypeError). That's probably fine; otherwise
other set implementations would be constrained to implementing a hash
that's compatible with ours.

Remove all imports from the compile() function; these are
now done at the top of the module ("Python normal form"),
and define a helper based on the platform instead of
testing the platform in the compile() function.
superficial errors and one deep one that aren't currently caught. I'm
headed for bed after this checkin.
- Fixed several typos introduced by Raymond Hettinger (through
cut-n-paste from my template): it's _as_temporarily_immutable, not
_as_temporary_immutable, and moreover when the element is added, we
should use _as_immutable.
- Made the seq argument to ImmutableSet.__init__ optional, so we can
write ImmutableSet() to create an immutable empty set.
- Rename the seq argument to Set and ImmutableSet to iterable.
- Add a Set.__hash__ method that raises a TypeError. We inherit a
default __hash__ implementation from object, and we don't want that.
We can then catch this in update(), so that
e.g. s.update([Set([1])]) will transform the Set([1]) to
ImmutableSet([1]).
- Added the dance to catch TypeError and try _as_immutable in the
constructors too (by calling _update()). This is needed so that
Set([Set([1])]) is correctly interpreted as
Set([ImmutableSet([1])]). (I was puzzled by a side effect of this
and the inherited __hash__ when comparing two sets of sets while
testing different powerset implementations: the Set element passed
to a Set constructor wasn't transformed to an ImmutableSet, and then
the dictionary didn't believe the Set found in one dict it was the
same as ImmutableSet in the other, because the hashes were
different.)
- Refactored Set.update() and both __init__() methods; moved the body
of update() into BaseSet as _update(), and call this from __init__()
and update().
- Changed the NotImplementedError in BaseSet.__init__ to TypeError,
both for consistency with basestring() and because we have to use
TypeError when denying Set.__hash__. Together those provide
sufficient evidence that an unimplemented method needs to raise
TypeError.
2045, section 5.2 states that if the Content-Type: header is
syntactically invalid, the default type should be text/plain.
Implement minimal sanity checking of the header -- it must have
exactly one slash in it. This closes SF patch #597593 by Skip, but in
a different way.
Note that these methods used to raise ValueError for invalid ctypes,
but now they won't.
get the MIME main and sub types, instead of getting the whole ctype
and splitting it here. The two more specific methods now correctly
implement RFC 2045, section 5.2.
Jeremy reported that this is not allowed by RFC 2396; however,
other tools support unescaped @'s so we should also.
Apply SF patch 596581 closing bug 581529.
Also, don't call gettempdir() in the default expression for the 'dir'
argument to various functions; use 'dir=None' for the default and
insert 'if dir is None: dir = gettemptir()' in the bodies. That way
the work done by gettempdir is postponed until needed.
Loosened the acceptable 'start' and 'stop' arguments so that any
Python (bounded) ints can be used. So, e.g., randrange(-sys.maxint-1,
sys.maxint) no longer blows up.

Although Cygwin attempts to be as Posix compliant
as possible, it has difficulties unlinking open
files. This is not surprising given that Cygwin is
dependent on Win32 which in turn has this problem
itself.
The attached tempfile patch acknowledges this
Cygwin limitation. Without this patch, Cygwin
fails test_tempfile (i.e., test_has_no_name) as
