Guido van Rossum 919cf1aff1 New, better hash for floating point and complex 1997-01-11 19:26:21 +00:00
Guido van Rossum 80dd9b6672 Subtle change to hex/oct formatting so the largest negative number 
does not receive a minus sign.
 1997-01-10 17:39:30 +00:00
Guido van Rossum 541cdd84ac Fix overflow test for multiply to catch some cases it missed. 
Added warning about dependency of float/complex hash on int hash.
 1997-01-06 22:53:20 +00:00
Guido van Rossum 53756b1097 Added PyLong_FromUnsignedLong() and PyLong_AsUnsignedLong(). 1997-01-03 17:14:46 +00:00
Guido van Rossum babab6869f Removed all traces of accessobject.c. 1996-12-25 19:22:49 +00:00
Barry Warsaw f90eddef5d PySequence_Index(): set exception when object is not found in 
sequence, otherwise

operator.indexOf([4, 3, 2, 1], 9) would raise a SystemError!

Note: it might be wise to double check all these functions.  I haven't
done that yet.
 1996-12-18 19:32:18 +00:00
Guido van Rossum 0969ad213d Better tuple hash function. 1996-12-16 17:55:46 +00:00
Guido van Rossum cc15b42e59 Change comment about MINSIZE -- 10 is optimal for Python. 1996-12-16 03:32:39 +00:00
Guido van Rossum 3176bb1df2 Some more tuning of quicksort: use pointers instead of indexing. 1996-12-11 23:57:39 +00:00
Guido van Rossum 3f236dee3a Added new quicksort implementation, tailored to sorting arrays of 
object pointers.  Should be a bit faster than the C library's qsort(),
and doesn't have the prohibition on recursion that Solaris qsort() has
in the threaded version of their C library.

Thanks to discussions with Tim Peters.
 1996-12-10 23:55:39 +00:00

Guido van Rossum da9c2710c7 Make gcc -Wall happy 1996-12-05 21:58:58 +00:00
Guido van Rossum 472c04f18f Fix newlongobject so it will work for 64-bit as well as 32-bit hardware 
(although for 32-bit hardware it's a bit slower than it was).

Make gcc -Wall happy.
 1996-12-05 21:57:21 +00:00
Guido van Rossum a0a69b8b42 Experimental new implementation of dictionary comparison. This 
defines that a shorter dictionary is always smaller than a longer one.
For dictionaries of the same size, the smallest differing element
determines the outcome (which yields the same results as before,
without explicit sorting).
 1996-12-05 21:55:55 +00:00
Guido van Rossum 685a38ea94 Make gcc -Wall happy. 1996-12-05 21:54:17 +00:00

Make gcc -Wall happy.
 1996-12-05 21:52:32 +00:00
Guido van Rossum 3c5936afc5 Added missing PySequence_List. 
Correct typo in error msg (expec[t]ed).
Make gcc -Wall happy.
 1996-12-05 21:51:24 +00:00

Guido van Rossum fde7a75b78 Fixed compare function to do first char comparison in unsigned mode, 
for consistency with the way other characters are compared.
 1996-10-23 14:19:40 +00:00
Guido van Rossum 8bcf369cf9 Support passing in an empty dictionary of keywords to newinstanceobject. 1996-10-21 15:12:32 +00:00
Guido van Rossum e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should 
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
 1996-10-11 16:25:41 +00:00
Guido van Rossum 336c699236 Fix subtle bug detected by Jim F. 1996-09-30 22:00:50 +00:00

long, float.

Raise exception instead of dumping core for remainder and divmod.

code by using abstract.c:PyObject_GetItem().
 1996-05-21 22:44:20 +00:00
Guido van Rossum 6dabc98400 Added __name__ attribute to class instance method objects.

Sjoerd Mullender 6f011d7ad5 Get ordering right for TRACE_REFS/COUNT_ALLOCS combination (otherwise 
may get inc_count sanity check abort).
 1995-09-18 10:49:04 +00:00
Sjoerd Mullender 6ec3c653da Implemented two new functions in sys: 
getcounts() returns a list of counts of allocations and
		deallocations for all different object types.
	getobjects(n [, type ]) returns a list of recently allocated
		and not-yet-freed objects of the given type (all
		objects if no type given).  Only the n most recent
		(all if n==0) objects are returned.
getcounts is only available if compiled with -DCOUNT_ALLOCS,
getobjects is only available if compiled with -DTRACE_REFS.  Note that
everything must be compiled with these options!

	documentation strings to classes and methods
 1995-01-07 12:35:18 +00:00
Guido van Rossum cab650db8e * Objects/methodobject.c: changed drastically, the object now

	static); added attributes __name__, __doc__ and __self__
 1995-01-07 12:34:58 +00:00

Guido van Rossum bb3c5f7406 fix comparison of instances without _-cmp__ 1994-11-10 22:31:02 +00:00
Sjoerd Mullender b9a6d12498 Comparison of two class instances without __cmp__ or __rcmp__ methods 
was broken.
 1994-10-19 15:11:52 +00:00
Guido van Rossum 03093a248d * Include/classobject.h, Objects/classobject.c, Python/ceval.c: 
entirely redone operator overloading.  The rules for class
	instances are now much more relaxed than for other built-in types
	(whose coerce must still return two objects of the same type)

	* Objects/floatobject.c: add overflow check when converting float
	to int and implement truncation towards zero using ceil/float

	* Objects/longobject.c: change ValueError to OverflowError when
	converting to int

	* Objects/rangeobject.c: modernized

	* Objects/stringobject.c: use HAVE_LIMITS instead of __STDC__

	* Objects/xxobject.c: changed to use new style (not finished?)

env at configure time and will then be put in all Makefiles as
	default

Guido van Rossum 91ab4a8353 If an attribute is deleted, __setattr__ is called with 2 instead of 3 
arguments (adding __delattr__ was deemed too much overhead)

Guido van Rossum 0b7d02a36f New patches by Andrew to fix various problems 1994-08-12 12:52:35 +00:00
Guido van Rossum e149fa2a1e * Objects/classobject.c, Include/classobject.h: added __getattr__ 
and __setattr__ support to override getattr(x, name) and
	setattr(x, name, value) for class instances.  This uses a special
	hack whereby the class is supposed to be static: the __getattr__
	and __setattr__ methods are looked up only once and saved in the
	instance structure for speed

Guido van Rossum 455b87d457 New file 1993-12-20 11:43:21 +00:00
Guido van Rossum 590baa4a7a * import.c (get_module): pass .py filename to parse_file, not .pyc filename! 
* funcobject.c (func_repr): don't call getstringvalue(None) for anonymous
  functions.
* bltinmodule.c: removed lambda (which is now a built-in function);
  removed implied lambda for string arg to filter/map/reduce.
* Grammar, graminit.[ch], compile.[ch]: replaced lambda as built-in
  function by lambda as grammar entity: instead of "lambda('x: x+1')" you
  write "lambda x: x+1".
* Xtmodule.c (checkargdict): return 0, not NULL, for error.

Guido van Rossum b376a4ad18 * timemodule.c: Add hack for Solaris 2. 
* posixmodule.c: don't prototype getcwd() -- it's not portable...
* mappingobject.c: double-check validity of last_name_char in
  dict{lookup,insert,remove}.
* arraymodule.c: need memmove only for non-STDC Suns.
* Makefile: comment out HTML_LIBS and XT_USE by default
* pythonmain.c: don't prototype getopt() -- it's not standardized
* socketmodule.c: cast flags arg to {get,set}sockopt() and addrbuf arg to
  recvfrom() to (ANY*).
* pythonrun.c (initsigs): fix prototype, make it static
* intobject.c (LONG_BIT): only #define it if not already defined
* classobject.[ch]: remove all references to unused instance_convert()
* mappingobject.c (getmappingsize): Don't return NULL in int function.
