* Fix for http://sourceforge.net/bugs/?func=detailbug&bug_id=111866&group_id=5470.Tim Peters2000-08-151-1/+1
| | | | | | | | | | | This was a misleading bug -- the true "bug" was that hash(x) gave an error return when x is an infinity. Fixed that. Added new Py_IS_INFINITY macro to pyport.h. Rearranged code to reduce growing duplication in hashing of float and complex numbers, pushing Trent's earlier stab at that to a logical conclusion. Fixed exceedingly rare bug where hashing of floats could return -1 even if there wasn't an error (didn't waste time trying to construct a test case, it was simply obvious from the code that it *could* happen). Improved complex hash so that hash(complex(x, y)) doesn't systematically equal hash(complex(y, x)) anymore.

* Cray J90 fixes for long ints.Tim Peters2000-07-081-5/+8
| | | | | | | | | | | | | | | | This was a convenient excuse to create the pyport.h file recently discussed! Please use new Py_ARITHMETIC_RIGHT_SHIFT when right-shifting a signed int and you *need* sign-extension. This is #define'd in pyport.h, keying off new config symbol SIGNED_RIGHT_SHIFT_ZERO_FILLS. If you're running on a platform that needs that symbol #define'd, the std tests never would have worked for you (in particular, at least test_long would have failed). The autoconfig stuff got added to Python after my Unix days, so I don't know how that works. Would someone please look into doing & testing an auto-config of the SIGNED_RIGHT_SHIFT_ZERO_FILLS symbol? It needs to be defined if & only if, e.g., (-1) >> 3 is not -1.
* The tail end of x_sub implicitly assumed that an unsigned shortTim Peters2000-07-081-0/+1

* Got RID of redundant coercions in longobject.c (as spotted by GregTim Peters2000-07-081-6/+3
| | | | | | | Stein -- thanks!). Incidentally removed all the Py_PROTO macros from object.h, as they prevented my editor from magically finding the definitions of the "coercion", "cmpfunc" and "reprfunc" typedefs that were being redundantly applied in longobject.c.

* Trent Mick <trentm@ActiveState.com>:Fred Drake2000-06-011-2/+2
| | | | | | | This patch correct bounds checking in PyLong_FromLongLong. Currently, it does not check properly for negative values when checking to see if the incoming value fits in a long or unsigned long. This results in possible silent truncation of the value for very large negative values.
* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-1/+1
| | | | | | | | | | For more comments, read the patches@python.org archives. For documentation read the comments in mymalloc.h and objimpl.h. (This is not exactly what Vladimir posted to the patches list; I've made a few changes, and Vladimir sent me a fix in private email for a problem that only occurs in debug mode. I'm also holding back on his change to main.c, which seems unnecessary to me.)
* Simple optimization by Christian Tismer, who gives credit to LennyGuido van Rossum2000-04-101-0/+9
| | | | | Kneler for reporting this issue: long_mult() is faster when the smaller argument is on the left. Swap the arguments accordingly.

Checkin messages: New Unicode support for int(), float(), complex() and long(). - new APIs PyInt_FromUnicode() and PyLong_FromUnicode() - added support for Unicode to PyFloat_FromString() - new encoding API PyUnicode_EncodeDecimal() which converts Unicode to a decimal char* string (used in the above new APIs) - shortcuts for calls like int(<int object>) and float(<float obj>) - tests for all of the above Unicode compares and contains checks: - comparing Unicode and non-string types now works; TypeErrors are masked, all other errors such as ValueError during Unicode coercion are passed through (note that PyUnicode_Compare does not implement the masking -- PyObject_Compare does this) - contains now works for non-string types too; TypeErrors are masked and 0 returned; all other errors are passed through Better testing support for the standard codecs. Misc minor enhancements, such as an alias dbcs for the mbcs codec. Changes: - PyLong_FromString() now applies the same error checks as does PyInt_FromString(): trailing garbage is reported as error and not longer silently ignored. The only characters which may be trailing the digits are 'L' and 'l' -- these are still silently ignored. - string.ato?() now directly interface to int(), long() and float(). The error strings are now a little different, but the type still remains the same. These functions are now ready to get declared obsolete ;-) - PyNumber_Int() now also does a check for embedded NULL chars in the input string; PyNumber_Long() already did this (and still does) Followed by: Looks like I've gone a step too far there... (and test_contains.py seem to have a bug too). I've changed back to reporting all errors in PyUnicode_Contains() and added a few more test cases to test_contains.py (plus corrected the join() NameError).
* long_format(): Now takes a third parameter, addL; iff true, aFred Drake1999-12-231-9/+19

Remove incorrect statement about external use of this function from elsewhere; it's static! long_str(): Handler for the tp_str slot in the type object. Identical to long_repr(), but passes false as the addL parameter of long_format().

* Patch by Mark Hammond to support 64-bit ints on MS platforms.Guido van Rossum1998-08-251-22/+22
| | | | | | The MS compiler doesn't call it 'long long', it uses __int64, so a new #define, LONG_LONG, has been added and all occurrences of 'long long' are replaced with it.
* Two patches by Jason Harper:Guido van Rossum1998-08-111-37/+96
| | | | | | - Faster conversion to string for binary bases: linear instead of quadratic! - Allocate smaller result for certain masking ops, e.g. (1L<<30000) & 1.

OverflowError: long int too long to convert >>> 2) If C does not sign-extend, some genuine overflows won't be caught. The attached should repair both, and, because I installed a new disk and a C compiler today, it's even been compiled this time <wink>.
