* Rationalize use of limits.h, moving the inclusion to Python.h.Fred Drake2000-09-261-1/+0
| | | | | | | | Add definitions of INT_MAX and LONG_MAX to pyport.h. Remove includes of limits.h and conditional definitions of INT_MAX and LONG_MAX elsewhere. This closes SourceForge patch #101659 and bug #115323.
* Use symbolic constants for allowable short ranges.Martin v. Löwis2000-09-151-4/+7

* Check range for bytes and shorts. Closes bug #110845.Martin v. Löwis2000-09-151-2/+42

* REMOVED all CWI, CNRI and BeOpen copyright markings.Guido van Rossum2000-09-011-9/+0
| | | | This should match the situation in the 1.6b1 tree.
* merge Include/my*.h into Include/pyport.hPeter Schneider-Kamp2000-07-311-1/+0
| | | | marked my*.h as obsolete
* Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',Thomas Wouters2000-07-211-1/+1
| | | | | | | | | | | | | | | | | | and a couple of functions that were missed in the previous batches. Not terribly tested, but very carefully scrutinized, three times. All these were found by the little findkrc.py that I posted to python-dev, which means there might be more lurking. Cases such as this: long func(a, b) long a; long b; /* flagword */ { and other cases where the last ; in the argument list isn't followed by a newline and an opening curly bracket. Regexps to catch all are welcome, of course ;)

* Michael Hudson <mwh21@cam.ac.uk>:Fred Drake2000-06-011-1/+2
| | | | | Removed PyErr_BadArgument() calls and replaced them with more useful error messages.

* Patches from Greg Stein to support 'P' format in struct module'sGuido van Rossum1998-09-181-0/+31
| | | | | native format, as void* (translated to Python int or long). Also adds PyLong_FromVoidPtr and PyLong_AsVoidPtr to longobject.c.

* Oops, left in a non-standard multi-line doc string that GCC finds okayGuido van Rossum1997-12-211-4/+4

* Fix due to Bill Noon for problem discovered by Ken Manheimer: packingGuido van Rossum1997-11-041-2/+2
| | | | 0.0 as float or double would yield the representation for 1.0!
* Apply two changes, systematically:Guido van Rossum1997-10-011-5/+3
| | | | | | | | | | | | | | | | | (1) Use PyErr_NewException("module.class", NULL, NULL) to create the exception object. (2) Remove all calls to Py_FatalError(); instead, return or ignore the errors -- the import code now checks PyErr_Occurred() after calling a module's init function, so it's no longer a fatal error for the initialization to fail. Also did some small cleanups, e.g. removed unnecessary test for "already initialized" from initfpectl(), and unified initposix()/initnt(). I haven't checked this very thoroughly, so while the changes are pretty trivial -- beware of untested code!
* Contribution by Hannu Krosing (with some changes).Guido van Rossum1997-09-051-0/+38
| | | | | | | Added 'p' format character for Pascal string (i.e. leading length byte). This uses the count prefix line 's' does, except that the count includes the length byte; i.e. '10p' takes 10 bytes packed but has space for a length byte and 9 data bytes.
* Ignore whitespace between formats (not internal to a count+format).Guido van Rossum1997-08-261-0/+7

* Keep Microsoft VC happy.Guido van Rossum1997-04-111-8/+8

* Changed the ``add/sub_offset'' hacks for dealing with C's unsignedGuido van Rossum1997-01-031-112/+14
| | | | | | | int/long types, and use the new PyLong_FromUnsignedLong() and PyLong_AsUnsignedLong() interfaces instead. Semantic change: the 'I' format will now always return a long int.
* Fill pad bytes with zeros (fixing a bug dating from the very first version!).Guido van Rossum1997-01-031-2/+5

* Scratch the ears of gcc -Wall.Barry Warsaw1997-01-031-1/+1

* Ok, ok, I've fixed gradual underflow on packing too.Guido van Rossum1997-01-021-45/+47
| | | | | | Still don't know what to do with Inf/NaN, so I raise an exception on pack(), and something random decided by ldexp() will happen on unpack().
* Oops -- unpack float/double didn't do the right thing if e==0.Guido van Rossum1997-01-021-4/+14
|
* Support float and double in non-native formats.Guido van Rossum1997-01-021-2/+365
| | | | | These use the ANSI/IEEE standard, which is also used by XDR; so the _xdr module may become obsolete.
* Added better handling of unsigned longs -- a Python long returned byGuido van Rossum1996-12-311-27/+163
| | | | unpack('L', ...) is now acceptable to pack('L', ...).
* Fix the first bugs... treatment of 0 count was wrong, and memchr()Guido van Rossum1996-12-311-6/+6

* Pretty much rewritten to fulfull several long-standing wishes:Guido van Rossum1996-12-311-226/+572
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -- The whole implementation is now more table-driven. -- Unsigned integers. Format characters 'B', 'H', 'I' and 'L' mean unsigned byte, short, int and long. For 'I' and 'L', the return value is a Python long integer if a Python plain integer can't represent the required range (note: this is dependent on the size of the relevant C types only, not of the sign of the actual value). -- A new format character 's' packs/unpacks a string. When given a count prefix, this is the size of the string, not a repeat count like for the other format characters; e.g. '10s' means a single 10-byte string, while '10c' means 10 characters. For packing, the string is truncated or padded with null bytes as appropriate to make it fit. For unpacking, the resulting string always has exactly the specified number of bytes. As a special case, '0s' means a single, empty string (while '0c' means 0 characters). -- Various byte order options. The first character of the format string determines the byte order, size and alignment, as follows: First character Byte order size and alignment '@' native native '=' native standard '<' little-endian standard '>' big-endian standard '!' network (= big-endian) standard If the first character is not one of these, '@' is assumed. Native byte order is big-endian or little-endian, depending on the host system (e.g. Motorola and Sun are big-endian; Intel and DEC are little-endian). Native size and alignment are determined using the C compiler's sizeof expression. This is always combined with native byte order. Standard size and alignment are as follows: no alignment is required for any type (so you have to use pad bytes); short is 2 bytes; int and long are 4 bytes. In this mode, there is no support for float and double. Note the difference between '@' and '=': both use native byte order, but the size and alignment of the latter is standardized. The form '!' is available for those poor souls who can't remember whether network byte order is big-endian or little-endian. There is no way to indicate non-native byte order (i.e. force byte-swapping); use the appropriate choice of '<' or '>'.

* * Changed all copyright messages to include 1993.Guido van Rossum1993-03-291-2/+2
| | | | | | | | | | | | | | | | | * Stubs for faster implementation of local variables (not yet finished) * Added function name to code object. Print it for code and function objects.
