* SF patch #998993: The UTF-8 and the UTF-16 stateful decoders now supportWalter Dörwald2004-09-071-0/+21
| | | | | | | | | | | decoding incomplete input (when the input stream is temporarily exhausted). codecs.StreamReader now implements buffering, which enables proper readline support for the UTF-16 decoders. codecs.StreamReader.read() has a new argument chars which specifies the number of characters to return. codecs.StreamReader.readline() and codecs.StreamReader.readlines() have a new argument keepends. Trailing "\n"s will be stripped from the lines if keepends is false. Added C APIs PyUnicode_DecodeUTF8Stateful and PyUnicode_DecodeUTF16Stateful.

* SF patch 936813: fast modular exponentiationTim Peters2004-08-301-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | This checkin is adapted from part 2 (of 3) of Trevor Perrin's patch set. BACKWARD INCOMPATIBILITY: SHIFT must now be divisible by 5. AFAIK, nobody will care. long_pow() could be complicated to worm around that, if necessary. long_pow(): - BUGFIX: This leaked the base and power when the power was negative (and so the computation delegated to float pow). - Instead of doing right-to-left exponentiation, do left-to-right. This is more efficient for small bases, which is the common case. - In addition, if the exponent is large (more than FIVEARY_CUTOFF digits), precompute [a**i % c for i in range(32)], and go left to right 5 bits at a time. l_divmod(): - The signature changed so that callers who don't want the quotient, or don't want the remainder, can pass NULL in the slot they don't want. This saves them from having to declare a vrbl for unwanted stuff, and remembering to decref it. long_mod(), long_div(), long_classic_div(): - Adjust to new l_divmod() signature, and simplified as a result.
* SF patch 936813: fast modular exponentiationTim Peters2004-08-291-1/+1
| | | | | | | | | | | | | | | | | | This checkin is adapted from part 1 (of 3) of Trevor Perrin's patch set. x_mul() - sped a little by optimizing the C - sped a lot (~2X) if it's doing a square; note that long_pow() squares often k_mul() - more cache-friendly now if it's doing a square KARATSUBA_CUTOFF - boosted; gradeschool mult is quicker now, and it may have been too low for many platforms anyway KARATSUBA_SQUARE_CUTOFF - new - since x_mul is a lot faster at squaring now, the point at which Karatsuba pays for squaring is much higher than for general mult

* * drop the unreasonable list invariant that ob_item should never come backArmin Rigo2004-07-291-3/+1
| | | | | | | | | | | | | | | | | | | | | to NULL during the lifetime of the object. * listobject.c nevertheless did not conform to the other invariants, either; fixed. * listobject.c now uses list_clear() as the obvious internal way to clear a list, instead of abusing list_ass_slice() for that. It makes it easier to enforce the invariant about ob_item == NULL. * listsort() sets allocated to -1 during sort; any mutation will set it to a value >= 0, so it is a safe way to detect mutation. A negative value for allocated does not cause a problem elsewhere currently. test_sort.py has a new test for this fix. * listsort() leak: if items were added to the list during the sort, AND if these items had a __del__ that puts still more stuff into the list, then this more stuff (and the PyObject** array to hold them) were overridden at the end of listsort() and never released.
* Fix obscure breakage (relative to 2.3) in listsort: the test for listTim Peters2004-07-291-0/+3
| | | | | | | | | | | | mutation during list.sort() used to rely on that listobject.c always NULL'ed ob_item when ob_size fell to 0. That's no longer true, so the test for list mutation during a sort is no longer reliable. Changed the test to rely instead on that listobject.c now never NULLs-out ob_item after (if ever) ob_item gets a non-NULL value. This new assumption is also documented now, as a required invariant in listobject.h. The new assumption allowed some real simplification to some of the hairier code in listsort(), so is a Good Thing on that count.

* SF bug 994255: Py_RETURN_NONE causes too much warningsTim Peters2004-07-222-3/+3
| | | | | | | | | | Rewrote Py_RETURN_{NONE, TRUE, FALSE} to expand to comma expressions rather than "do {} while(0)" thingies. The OP complained because he likes using MS /W4 sometimes, and then all his uses of these things generate nuisance warnings about testing a constant expression (in the "while(0)" part). Comma expressions don't have this problem (although it's a lucky accident that comma expressions suffice for these macros!).

* Make weak references subclassable:Fred Drake2004-07-021-1/+6
| | | | | | | | | | | | | | | | | | | | | | - weakref.ref and weakref.ReferenceType will become aliases for each other - weakref.ref will be a modern, new-style class with proper __new__ and __init__ methods - weakref.WeakValueDictionary will have a lighter memory footprint, using a new weakref.ref subclass to associate the key with the value, allowing us to have only a single object of overhead for each dictionary entry (currently, there are 3 objects of overhead per entry: a weakref to the value, a weakref to the dictionary, and a function object used as a weakref callback; the weakref to the dictionary could be avoided without this change) - a new macro, PyWeakref_CheckRefExact(), will be added - PyWeakref_CheckRef() will check for subclasses of weakref.ref This closes SF patch #983019.
* SF Bug #215126: Over restricted type checking on eval() functionRaymond Hettinger2004-07-021-1/+1
| | | | | | The builtin eval() function now accepts any mapping for the locals argument. Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing down the normal case. My timings so no measurable impact.

| | | | | | | | | | | New include file timefuncs.h exports private API function _PyTime_DoubleToTimet() from timemodule.c. timemodule should export some other functions too (look for painful bits in datetimemodule.c). Added insane-argument checking to datetime's assorted fromtimestamp() and utcfromtimestamp() methods. Added insane-argument tests of these to test_datetime, and insane-argument tests for ctime(), localtime() and gmtime() to test_time.

| | | | | | | | | | | | | | (Code contributed by Jiwon Seo.) The documentation portion of the patch is being re-worked and will be checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's rationale for the design decisions on binding behavior (as described in in his patch comments and in discussions on python-dev). The test file, test_genexps.py, is written in doctest format and is meant to exercise all aspects of the the patch. Further additions are welcome from everyone. Please stress test this new feature as much as possible before the alpha release.
