* long_format(): Now takes a third parameter, addL; iff true, aFred Drake1999-12-231-9/+19
| | | | | | | | | | | | | | | trailing 'L' is appended to the representation, otherwise not. All existing call sites are modified to pass true for addL. 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().

* Changes for long file support by Steve Clift.Guido van Rossum1999-01-061-18/+0
| | | | (Really: moved a bunch of defs to longobject.h.)

* Patches from Greg Stein to support 'P' format in struct module'sGuido van Rossum1998-09-181-0/+55
| | | | | native format, as void* (translated to Python int or long). Also adds PyLong_FromVoidPtr and PyLong_AsVoidPtr to longobject.c.
* Undo victim of careless global substitute ("long long_hash" wasGuido van Rossum1998-09-131-1/+1
| | | | | changed to "LONG_LONG_hash" in the list of forward decls). Discovered by Jason Harper.
* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: "Tim Peters" <tim_one@email.msn.com> To: "Guido van Rossum" <guido@CNRI.Reston.VA.US> Date: Sat, 23 May 1998 21:45:53 -0400 Guido, the overflow checking in PyLong_AsLong is off a little: 1) If the C in use sign-extends right shifts on signed longs, there's a spurious overflow error when converting the most-negative int: Python 1.5.1 (#0, Apr 13 1998, 20:22:04) [MSC 32 bit (Intel)] on win32 Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam >>> x = -1L << 31 >>> x -2147483648L >>> int(x) Traceback (innermost last): File "<stdin>", line 1, in ? 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>.
