* On Windows, make sure SocketType is the same as socket. (SF bugGuido van Rossum2002-08-221-1/+1

* Change the binary operators |, &, ^, - to return NotImplemented ratherGuido van Rossum2002-08-221-14/+40
| | | | | | | | | | | | | | | | | | | | 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.

* Ouch. The test suite *really* needs work!!!!! There were severalGuido van Rossum2002-08-211-46/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Patch #595014: Cygwin tempfile patchJason Tishler2002-08-141-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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 follows: $ ./python -E -tt ../Lib/test/regrtest.py -l test_tempfile test_tempfile test test_tempfile failed -- Traceback (most recent call last): File "/home/jt/src/PythonCvs/Lib/test/test_tempfile.py", line 689, in test_has_no_name self.failOnException("rmdir", ei) File "/home/jt/src/PythonCvs/Lib/test/test_tempfile.py", line 33, in failOnException self.fail("%s raised %s: %s" % (what, ei[0], ei[1])) File "/home/jt/src/PythonCvs/Lib/unittest.py", line 260, in fail raise self.failureException, msg AssertionError: rmdir raised exceptions.OSError: [Errno 90] Directory not empty: '/mnt/c/DOCUME~1/jatis/LOCALS~1/Temp/tmpM_z8nj'

| | | | | | | | | | | | | do bizarre things to get a temp file, I changed it to use mkstemp instead of NamedTemporaryFile. This tried to leave the file open while passing its name to execfile(). On Win2K (but not Win9X), though, a file created with O_TEMPORARY cannot be opened again, so the test failed with a permission error when execfile tried to open it. Closer to the truth: a file created with O_TEMPORARY can be opened again, but only if the file is also created with SHARE_DELETE access via the Win32 CreateFile() function. There's no way to get at that from MS's version of libc, though (we'd have to ditch the "std" C file functions in favor of Win32 API calls).
