* SF bug 705836: struct.pack of floats in non-native endian orderTim Peters2003-03-201-12/+37
| | | | | | | | | | | | | | pack_float, pack_double, save_float: All the routines for creating IEEE-format packed representations of floats and doubles simply ignored that rounding can (in rare cases) propagate out of a long string of 1 bits. At worst, the end-off carry can (by mistake) interfere with the exponent value, and then unpacking yields a result wrong by a factor of 2. In less severe cases, it can end up losing more low-order bits than intended, or fail to catch overflow *caused* by rounding. Bugfix candidate, but I already backported this to 2.2. In 2.3, this code remains in severe need of refactoring.
* (Most of) SF patch 601369 (Christos Georgiou): obmalloc,structmodule:Guido van Rossum2002-09-031-27/+54
| | | | | | | 64bit, big endian (issue 2 only). This adds a bunch of memcpy calls via a temporary variable to avoid alignment errors. That's needed for some platforms.

* The 'p' (Pascal string) pack code acts unreasonably when the string sizeTim Peters2001-09-151-0/+2
| | | | | and count exceed 255. Changed to preserve as much of the string as possible (instead of count%256 characters).
* SF bug #442520: test_struct fails on SPARC.Tim Peters2001-07-181-4/+10
| | | | | | | | The ob_sval member of a string object isn't necessarily aligned to better than a native long, so the new "q" and "Q" struct codes can't get away w/ casting tricks on platforms where LONG_LONG requires stricter-than-long alignment. After I thought of a few elaborate workarounds, Guido bashed me over the head with the obvious memcpy approach, herewith implemented.
* The new {b,l}p_{u,}longlong() didn't check get_pylong()'s return for NULL.Tim Peters2001-06-131-0/+8
| | | | Repaired that, and added appropriate tests for it to test_struct.py.
* Added q/Q standard (x-platform 8-byte ints) mode in struct module.Tim Peters2001-06-121-55/+137
| | | | | | | | | | | | | | This completes the q/Q project. longobject.c _PyLong_AsByteArray: The original code had a gross bug: the most-significant Python digit doesn't necessarily have SHIFT significant bits, and you really need to count how many copies of the sign bit it has else spurious overflow errors result. test_struct.py: This now does exhaustive std q/Q testing at, and on both sides of, all relevant power-of-2 boundaries, both positive and negative. NEWS: Added brief dict news while I was at it.
* Trimmed trailing whitespace.Tim Peters2001-06-111-3/+3

* Simplify some convolution by simply not recognizing 'q' and 'Q' at allTim Peters2001-06-111-33/+0
| | | | in native mode on platforms that don't HAVE_LONG_LONG.
* Make clear in the docstring that "std" applies to both size and alignment,Tim Peters2001-06-111-6/+6
| | | | | | not just to alignment. Spotted by Guido. Bugfix candidate.
* Initial support for 'q' and 'Q' struct format codes: for now, only inTim Peters2001-06-101-1/+186
| | | | | | | | | | | | | | | | | | native mode, and only when config #defines HAVE_LONG_LONG. Standard mode will eventually treat them as 8-byte ints across all platforms, but that likely requires a new set of routines in longobject.c first (while sizeof(long) >= 4 is guaranteed by C, there's nothing in C we can rely on x-platform to hold 8 bytes of int, so we'll have to roll our own; I'm thinking of a simple pair of conversion functions, Python long to/from sized vector of unsigned bytes; that may be useful for GMP conversions too; std q/Q would call them with size fixed at 8). test_struct.py: In addition to adding some native-mode 'q' and 'Q' tests, got rid of unused code, and repaired a non-portable assumption about native sizeof(short) (it isn't 2 on some Cray boxes). libstruct.tex: In addition to adding a bit of 'q'/'Q' docs (more needed later), removed an erroneous footnote about 'I' behavior.
* Repair portability of sign extension when reading signed ints on boxesTim Peters2001-04-081-10/+6
| | | | | | | | | | where sizeof(long)==8. This *was* broken on boxes where signed right shifts didn't sign-extend, but not elsewhere. Unfortunately, apart from the Cray T3E I don't know of such a box, and Guido has so far refused to buy me any Cray machines for home Python testing <wink>. More immediately interesting would be if someone could please test this on *any* sizeof(long)==8 box, to make sure I didn't break it.
* 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

* REMOVED all CWI, CNRI and BeOpen copyright markings.Guido van Rossum2000-09-011-9/+0

* 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 ;)

* 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.
