* _PyLong_Sign(): remove an assert that needed a variable ndigits thatGuido van Rossum2003-02-031-3/+2
| | | | | | | | | wasn't used outside the assert (and hence caused a compiler warning about an unused variable in NDEBUG mode). The assert wasn't very useful any more. _PyLong_NumBits(): moved the calculation of ndigits after asserting that v != NULL.
* long_from_binary_base(): Sped this a little by computing the # of bitsTim Peters2003-02-021-6/+6
| | | | needed outside the first loop.

* long(string, base) now takes time linear in len(string) when base is aTim Peters2003-02-021-15/+108
| | | | | power of 2. Enabled the tail end of test_long() in pickletester.py because it no longer takes forever when run from test_pickle.py.
* cPickle.c: Full support for the new LONG1 and LONG4. Added comments.Tim Peters2003-02-021-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assorted code cleanups; e.g., sizeof(char) is 1 by definition, so there's no need to do things like multiply by sizeof(char) in hairy malloc arguments. Fixed an undetected-overflow bug in readline_file(). longobject.c: Fixed a really stupid bug in the new _PyLong_NumBits. pickle.py: Fixed stupid bug in save_long(): When proto is 2, it wrote LONG1 or LONG4, but forgot to return then -- it went on to append the proto 1 LONG opcode too. Fixed equally stupid cancelling bugs in load_long1() and load_long4(): they *returned* the unpickled long instead of pushing it on the stack. The return values were ignored. Tests passed before only because save_long() pickled the long twice. Fixed bugs in encode_long(). Noted that decode_long() is quadratic-time despite our hopes, because long(string, 16) is still quadratic-time in len(string). It's hex() that's linear-time. I don't know a way to make decode_long() linear-time in Python, short of maybe transforming the 256's-complement bytes into marshal's funky internal format, and letting marshal decode that. It would be more valuable to make long(string, 16) linear time. pickletester.py: Added a global "protocols" vector so tests can try all the protocols in a sane way. Changed test_ints() and test_unicode() to do so. Added a new test_long(), but the tail end of it is disabled because it "takes forever" under pickle.py (but runs very quickly under cPickle: cPickle proto 2 for longs is linear-time).

* Provide __module__ attributes for functions defined in C and Python.Jeremy Hylton2003-01-312-6/+68
| | | | | | | | | | | | | | __module__ is the string name of the module the function was defined in, just like __module__ of classes. In some cases, particularly for C functions, the __module__ may be None. Change PyCFunction_New() from a function to a macro, but keep an unused copy of the function around so that we don't change the binary API. Change pickle's save_global() to use whichmodule() if __module__ is None, but add the __module__ logic to whichmodule() since it might be used outside of pickle.
* Change the treatment of positions returned by PEP293Walter Dörwald2003-01-311-9/+17
| | | | | | | | | | | | | | | | error handers in the Unicode codecs: Negative positions are treated as being relative to the end of the input and out of bounds positions result in an IndexError. Also update the PEP and include an explanation of this in the documentation for codecs.register_error. Fixes a small bug in iconv_codecs: if the position from the callback is negative *add* it to the size instead of substracting it. From SF patch #677429.
* _PyLong_NumBits(): The definition of this was too specific to the quirkyTim Peters2003-01-311-8/+17
| | | | | | | | | needs of pickling longs. Backed off to a definition that's much easier to understand. The pickler will have to work a little harder, but other uses are more likely to be correct <0.5 wink>. _PyLong_Sign(): New teensy function to characterize a long, as to <0, ==0, or >0.
* Implement appropriate __getnewargs__ for all immutable subclassable builtinGuido van Rossum2003-01-297-4/+72
| | | | | | | | types. The special handling for these can now be removed from save_newobj(). Add some testing for this. Also add support for setting the 'fast' flag on the Python Pickler class, which suppresses use of the memo.
* Added new private API function _PyLong_NumBits. This will be used at theTim Peters2003-01-281-0/+35
| | | | | | | start for the C implemention of new pickle LONG1 and LONG4 opcodes (the linear-time way to pickle a long is to call _PyLong_AsByteArray, but the caller has no idea how big an array to allocate, and correct calculation is a bit subtle).
* Fix SF bug# 676155, RuntimeWarning with tp_compareNeal Norwitz2003-01-281-1/+4
| | | | Check return value of PyLong_AsDouble(), it can return an error.
* Recursive compare machinery: The code that intended to exempt tuplesTim Peters2003-01-201-9/+14
| | | | | | | | | | | | was broken because new-in-2.3 code added a tp_as_mapping slot to tuples. Repaired that. Added basic docs to check_recursion(). The code that intended to exempt tuples and strings was also broken here, and in 2.2: these should use PyXYZ_CheckExact(), not PyXYZ_Check() -- we can't know whether subclass instances are immutable. This part (and this part alone) is a bugfix candidate.

* Fix charmapencode_lookup(), so that a None value in the mappingWalter Dörwald2003-01-081-0/+2

* GvR's idea to use memset() for the most common special case of repeatingRaymond Hettinger2003-01-061-1/+5
| | | | | a single character. Shaves another 10% off the running time by avoiding the lg2(N) loops and cache effects for the other cases.
* Optimize string_repeat.Raymond Hettinger2003-01-061-2/+11
| | | | | | | | | | | Christian Tismer pointed out the high cost of the loop overhead and function call overhead for 'c' * n where n is large. Accordingly, the new code only makes lg2(n) loops. Interestingly, 'c' * 1000 * 1000 ran a bit faster with old code. At some point, the loop and function call overhead became cheaper than invalidating the cache with lengthy memcpys. But for more typical sizes of n, the new code runs much faster and for larger values of n it runs only a bit slower.
* PyCFunction_Call(): Combined two switch cases w/ identical bodies.Tim Peters2003-01-051-4/+2

* SF Patch #661440: Refactor and streamline PyCFunction_CallRaymond Hettinger2003-01-041-31/+41
| | | | | | | | | | | | | | Refactor code in PyCFunction_Call giving a modest (tiny) speed boost, a slight improvement in semantics (now detects invalid flag combinations), and (arguably) improved clarity (making it blindingly clear which flag combinations are allowed). All this comes at a cost of a few lines of code duplication. * Folded test for METH_KEYWORDS into the switch/case. * Deferred testing for an empty dictionary until when and where needed. * Make a similar deferral for filling the "size" variable. * Inverted the dictionary test so that the common case falls though instead of making a jump.

* Fix an out-of-bound index in pmerge() discovered by Zooko (SF bugGuido van Rossum2002-12-311-1/+2
| | | | | | | 645404). I'm not 100% sure this is the right fix, so I'll keep the bug report open for Samuele, but this fixes the index error and passes the test suite (and I can't see why it *shouldn't* be the right fix :-).

* SF #561244, Micro optimizationsNeal Norwitz2002-12-302-19/+36
| | | | | | Initialize the small integers and __builtins__ in startup. This removes some if conditions. Change XDECREF to DECREF for values which shouldn't be NULL.

* SF patch #659536: Use PyArg_UnpackTuple where possible.Raymond Hettinger2002-12-298-12/+12
| | | | | | | Obtain cleaner coding and a system wide performance boost by using the fast, pre-parsed PyArg_Unpack function instead of PyArg_ParseTuple function which is driven by a format string.

* SF # 654974, fix unchecked return values in structseqNeal Norwitz2002-12-181-2/+6
| | | | | | | Check return values after memory allocation. Also use Py_True instead of PyInt_FromLong(1) for bool value. Backport candidate.
* * Objects/fileobject.cGustavo Niemeyer2002-12-171-1/+1
| | | | | (file_read): Replaced assertion with mixed sign operation by a simple comment (thank you Raymond). The algorithm is clear enough in that point.
* This is Richie Hindle's patchMichael W. Hudson2002-12-171-1/+259
| | | | | | | | [ 643835 ] Set Next Statement for Python debuggers with a few tweaks by me: adding an unsigned or two, mentioning that not all jumps are allowed in the doc for pdb, adding a NEWS item and a note to whatsnew, and AuCTeX doing something cosmetic to libpdb.tex.
* Fixed bugGustavo Niemeyer2002-12-161-3/+30
| | | | | | | | | | | | | | | | | [#521782] unreliable file.read() error handling * Objects/fileobject.c (file_read): Clear errors before leaving the loop in all situations, and also check if some data was read before exiting the loop with an EWOULDBLOCK exception. * Doc/lib/libstdtypes.tex * Objects/fileobject.c Document that sometimes a read() operation can return less data than what the user asked, if running in non-blocking mode. * Misc/NEWS Document the fix.

* Patch #650653: Raise always value error if the table is not 256 bytes long.Martin v. Löwis2002-12-121-6/+6
|
* Change issubclass() so that recursive tuples (directly or indirectlyWalter Dörwald2002-12-122-5/+6
| | | | | | containing class objects) are allowed as the second argument. This makes issubclass() more similar to isinstance() where recursive tuples are allowed too.
* Enhance issubclass() and PyObject_IsSubclass() so that a tuple isWalter Dörwald2002-12-122-28/+49
| | | | | | | | | | | supported as the second argument. This has the same meaning as for isinstance(), i.e. issubclass(X, (A, B)) is equivalent to issubclass(X, A) or issubclass(X, B). Compared to isinstance(), this patch does not search the tuple recursively for classes, i.e. any entry in the tuple that is not a class, will result in a TypeError. This closes SF patch #649608.
