* Ka-Ping Yee <ping@lfw.org>:Fred Drake2000-10-241-2/+2
| | | | | | Changes to error messages to increase consistency & clarity. This (mostly) closes SourceForge patch #101839.
* SF bug 115831 and Ping's SF patch 101751, 0.0**-2.0 returns inf rather thanTim Peters2000-10-061-28/+35
| | | | | | | | | | raise ValueError. Checked in the patch as far as it went, but also changed all of ints, longs and floats to raise ZeroDivisionError instead when raising 0 to a negative number. This is what 754-inspired stds require, as the "true result" is an infinity obtained from finite operands, i.e. it's a singularity. Also changed float pow to not be so timid about using its square-and-multiply algorithm. Note that what math.pow does is unrelated to what builtin pow does, and will still vary by platform.
* Rationalize use of limits.h, moving the inclusion to Python.h.Fred Drake2000-09-261-30/+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.
* Replace SIGFPE paranoia around strtod and atof. I don't believe theseTim Peters2000-09-251-0/+4
| | | | | fncs are allowed to raise SIGFPE (see the C std), but OK by me if people using --with-fpectl want to pay for checking anyway.
* Fix for SF bug 110624: float literals behave inconsistently.Tim Peters2000-09-231-16/+44
| | | | | | | | | | | | | | | | | | | | | | | | I fixed the specific complaint but left the (many) large issues untouched. See the (very long) bug report discussion for why: http://sourceforge.net/bugs/?func=detailbug&group_id=5470&bug_id=110624 Note that while I left the interface to the undocumented public API function PyFloat_FromString alone, its 2nd argument is useless. From a comment block in the code: RED_FLAG 22-Sep-2000 tim PyFloat_FromString's pend argument is braindead. Prior to this RED_FLAG, 1. If v was a regular string, *pend was set to point to its terminating null byte. That's useless (the caller can find that without any help from this function!). 2. If v was a Unicode string, or an object convertible to a character buffer, *pend was set to point into stack trash (the auto temp vector holding the character buffer). That was downright dangerous. Since we can't change the interface of a public API function, pend is still supported but now *officially* useless: if pend is not NULL, *pend is set to NULL.

* PyFloat_FromString(): Move s_buffer[] up to the top-level functionBarry Warsaw2000-08-181-2/+1

* Fix for http://sourceforge.net/bugs/?func=detailbug&bug_id=111866&group_id=5470.Tim Peters2000-08-151-38/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | The common technique for printing out a pointer has been to cast to a long and use the "%lx" printf modifier. This is incorrect on Win64 where casting to a long truncates the pointer. The "%p" formatter should be used instead. The problem as stated by Tim: > Unfortunately, the C committee refused to define what %p conversion "looks > like" -- they explicitly allowed it to be implementation-defined. Older > versions of Microsoft C even stuck a colon in the middle of the address (in > the days of segment+offset addressing)! The result is that the hex value of a pointer will maybe/maybe not have a 0x prepended to it. Notes on the patch: There are two main classes of changes: - in the various repr() functions that print out pointers - debugging printf's in the various thread_*.h files (these are why the patch is large) Closes SourceForge patch #100505.
* This patch addresses two main issues: (1) There exist some non-fatalFred Drake2000-06-291-10/+11
| | | | | | | | | | | | | | | | | | | | errors in some of the hash algorithms. For exmaple, in float_hash and complex_hash a certain part of the value is not included in the hash calculation. See Tim's, Guido's, and my discussion of this on python-dev in May under the title "fix float_hash and complex_hash for 64-bit *nix" (2) The hash algorithms that use pointers (e.g. func_hash, code_hash) are universally not correct on Win64 (they assume that sizeof(long) == sizeof(void*)) As well, this patch significantly cleans up the hash code. It adds the two function _Py_HashDouble and _PyHash_VoidPtr that the various hashing routine are changed to use. These help maintain the hash function invariant: (a==b) => (hash(a)==hash(b))) I have added Lib/test/test_hash.py and Lib/test/output/test_hash to test this for some cases.
* Vladimir Marangozov's long-awaited malloc restructuring.Guido van Rossum2000-05-031-8/+6
| | | | | | | | | | 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.)
* Marc-Andre's third try at this bulk patch seems to work (except thatGuido van Rossum2000-04-051-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | his copy of test_contains.py seems to be broken -- the lines he deleted were already absent). 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).

* Tim Peters writes:Guido van Rossum1999-05-061-7/+19
| | | | | | | | | | 1. Fixes float divmod so that the quotient it returns is always an integral value. 2. Fixes float % and float divmod so that the remainder always gets the right sign (the current code uses a "are the signs different?" test that doesn't work half the time <wink> when the product of the divisor and the remainder underflows to 0).
* Fix a problem with Vladimir's PyFloat_Fini code: clear the free list; ifGuido van Rossum1999-03-191-5/+17

* OK, try again. Vladimir gave me a fix for the alignment bus error,Guido van Rossum1999-03-121-7/+56
