Sjoerd Mullender 3bb8a05947 Several optimizations and speed improvements.
cstubs: Use Matrix type instead of float[4][4].
1993-10-22 12:04:32 +00:00
Sjoerd Mullender 842d2ccdcd intobject.c: Save references to small integers, so that they can be
shared.  The default is to save references to the integers in
	the range -1..99.  The lower limit can be set by defining
	NSMALLNEGINTS (absolute value of smallest integer to be saved)
	and NSMALLPOSINTS (1 more than the largest integer to be
	saved).
tupleobject.c: Save a reference to the empty tuple to be returned
	whenever a tuple of size 0 is requested.  Tuples of size 1
	upto, but not including, MAXSAVESIZE (default 20) are put in
	free lists when deallocated.  When MAXSAVESIZE equals 1, only
	share references to the empty tuple, when MAXSAVESIZE equals
	0, don't include the code at all and revert to the old
	behavior.
object.c: Print some more statistics when COUNT_ALLOCS is defined.

Sjoerd Mullender a9c3c22c33 * Extended X interface: pixmap objects, colormap objects visual objects,
image objects, and lots of new methods.
* Added counting of allocations and deallocations of builtin types if
  COUNT_ALLOCS is defined.  Had to move calls to NEWREF down in some
  files.
* Bug fix in sorting lists.
1993-10-11 12:54:31 +00:00
Guido van Rossum ed18fdc9fc * accessobject.c (ownercheck): allow a base class access to protected
objects of its derived classes; allow anything that has an attribute
  named "__privileged__" access to anything.
* object.[ch]: added hasattr() -- test whether getattr() will succeed.
1993-07-11 19:55:34 +00:00
Guido van Rossum 6ac258d381 * pythonrun.c: Print exception type+arg *after* stack trace instead of
before it.
* ceval.c, object.c: moved testbool() to object.c (now extern visible)
* stringobject.c: fix bugs in and rationalize string resize in formatstring()
* tokenizer.[ch]: fix non-working code for lines longer than BUFSIZ
1993-05-12 08:24:20 +00:00
Guido van Rossum 9bfef44d97 * Changed all copyright messages to include 1993.
* Stubs for faster implementation of local variables (not yet finished)
* Added function name to code object.  Print it for code and function
  objects.  THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version
  number has changed accordingly)
* Print address of self for built-in methods
* New internal functions getattro and setattro (getattr/setattr with
  string object arg)
* Replaced "dictobject" with more powerful "mappingobject"
* New per-type functio tp_hash to implement arbitrary object hashing,
  and hashobject() to interface to it
* Added built-in functions hash(v) and hasattr(v, 'name')
* classobject: made some functions static that accidentally weren't;
  added __hash__ special instance method to implement hash()
* Added proper comparison for built-in methods and functions
1993-03-29 10:43:31 +00:00
Guido van Rossum 7066dd75c5 * Makefile: added IMGFILE; moved some stuff around.
* flmodule.c: added some missing functions; changed readonly flags of
  some data members based upon FORMS documentation.
* listobject.c: fixed int/long arg lint bug (bites PC compilers).
* several: removed redundant print methods (repr is good enough).
* posixmodule.c: added (still experimental) process group functions.

Guido van Rossum 2e8f6140ff If a type has a repr function but no print function, printing it now
calls the repr function.  When the refcount is bad, don't print
the object at all (chances of crashes).
Changes to checking and printing of references: the consistency
check is somewhat faster; don't print strings referenced once
(most occur in function's name lists).
