* Patch #588564: _locale library patchJason Tishler2002-08-141-1/+6
| | | | | | | This patch enables setup.py to find gettext routines when they are located in libintl instead of libc. Although I developed this patch for Cygwin, I hope that it can be easily updated to support other platforms (if necessary). I tested this patch under Cygwin and Red Hat Linux 7.1.

| | | | | | | | | | | | | 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).
* mkstemp(): Repaired error in docstring (the sense of the 'binary' flagTim Peters2002-08-141-2/+2

* mkstemp(): The optional "binary" argument is clearly intended to be aTim Peters2002-08-131-1/+1

* k_mul(): The fix for (ah+al)*(bh+bl) spilling 1 bit beyond the allocatedTim Peters2002-08-131-8/+44
| | | | | | | | | | space is no longer needed, so removed the code. It was only possible when a degenerate (ah->ob_size == 0) split happened, but after that fix went in I added k_lopsided_mul(), which saves the body of k_mul() from seeing a degenerate split. So this removes code, and adds a honking long comment block explaining why spilling out of bounds isn't possible anymore. Note: ff we end up spilling out of bounds anyway <wink>, an assert in v_iadd() is certain to trigger.
* Regress Guido's change of 2002/08/06 to check for the zlib versionBarry Warsaw2002-08-131-4/+13
| | | | | 1.1.4. Redhat hasn't upgraded but does provide a patched 1.1.3 package, so checking for 1.1.4 just makes life difficult.

* Bug #556025: list(xrange(1e9)) --> seg faultJason Tishler2002-08-131-0/+5
| | | | | | | | | Close the bug report again -- this time for Cygwin due to a newlib bug. See the following for the details: http://sources.redhat.com/ml/newlib/2002/msg00369.html Note that this commit is only a documentation (i.e., comment) change.
* Add an improvement wrinkle to Neil Schemenauer's change to int_mulGuido van Rossum2002-08-131-2/+4
| | | | | | | (rev. 2.86). The other type is only disqualified from sq_repeat when it has the CHECKTYPES flag. This means that for extension types that only support "old-style" numeric ops, such as Zope 2's ExtensionClass, sq_repeat still trumps nb_multiply.
* test_division(): Added one larger digits value, to ensure that theTim Peters2002-08-131-1/+2
| | | | "lopsided Karatsuba" driver also gets some exercise.
* Machines-- and Python --are a lot faster in relevant ways since thisTim Peters2002-08-131-3/+5
| | | | | | test was written. So boosted the number of "digits" this generates, and also beefed up the "* / divmod" test to tickle numbers big enough to trigger the Karatsuba algorithm. It takes about 2 seconds now on my box.
* Fix comment for PyLong_AsUnsignedLong() to say that the return valueGuido van Rossum2002-08-131-1/+1

| | | | | | | | k_mul() when inputs have vastly different sizes, and a little more efficient when they're close to a factor of 2 out of whack. I consider this done now, although I'll set up some more correctness tests to run overnight.

* k_mul(): Moved an assert down. In a debug build, interrupting aTim Peters2002-08-121-2/+2

* k_mul(): White-box testing turned up that (ah+al)*(bh+bl) can, in rareTim Peters2002-08-121-3/+11
| | | | | | | | | cases, overflow the allocated result object by 1 bit. In such cases, it would have been brought back into range if we subtracted al*bl and ah*bh from it first, but I don't want to do that because it hurts cache behavior. Instead we just ignore the excess bit when it appears -- in effect, this is forcing unsigned mod BASE**(asize + bsize) arithmetic in a case where that doesn't happen all by itself.

* Refactor how __dict__ and __weakref__ interact with __slots__.Guido van Rossum2002-08-121-55/+147
| | | | | | | | | | | | | | | | | | | | | | | 1. You can now have __dict__ and/or __weakref__ in your __slots__ (before only __weakref__ was supported). This is treated differently than before: it merely sets a flag that the object should support the corresponding magic. 2. Dynamic types now always have descriptors __dict__ and __weakref__ thrust upon them. If the type in fact does not support one or the other, that descriptor's __get__ method will raise AttributeError. 3. (This is the reason for all this; it fixes SF bug 575229, reported by Cesar Douady.) Given this code: class A(object): __slots__ = [] class B(object): pass class C(A, B): __slots__ = [] the class object for C was broken; its size was less than that of B, and some descriptors on B could cause a segfault. C now correctly inherits __weakrefs__ and __dict__ from B, even though A is the "primary" base (C.__base__ is A). 4. Some code cleanup, and a few comments added.
* x_mul(): Made life easier for C optimizers in the "grade school"Tim Peters2002-08-121-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | algorithm. MSVC 6 wasn't impressed <wink>. Something odd: the x_mul algorithm appears to get substantially worse than quadratic time as the inputs grow larger: bits in each input x_mul time k_mul time ------------------ ---------- ---------- 15360 0.01 0.00 30720 0.04 0.01 61440 0.16 0.04 122880 0.64 0.14 245760 2.56 0.40 491520 10.76 1.23 983040 71.28 3.69 1966080 459.31 11.07 That is, x_mul is perfectly quadratic-time until a little burp at 2.56->10.76, and after that goes to hell in a hurry. Under Karatsuba, doubling the input size "should take" 3 times longer instead of 4, and that remains the case throughout this range. I conclude that my "be nice to the cache" reworkings of k_mul() are paying.
